Construction Of Metal Sharpening And Dulling Device

ABSTRACT  As  a result of modern development in Science and Technology, most of the large scale industrial used machine were now modernized to simple small and efficient machines. Some of these machines were either operated manually or the aid of electricity.  For this reason, big metal sharpening machine was here reduced to simple term, which can be operated manually such as file and grinding machine for production firms and homes.  This machine performs the same functions as the large i...

Design and Implementation of a Software Intercom on LAN

ABSTRACT In a developing economy like Nigeria financial resources are scarce commodity. Hence, cheaper means of accomplishing tasks even within the presence of scarce resources are always explored. This paper presents the design and implementation of a software intercom on local area network (LAN). The design provides a solution that eliminates the use of expensive hard-wired intercoms and Private Automatic Branch Exchange (PABX) by making use of only LAN and full multimedia computer allowing...

Design and Fabrication of an Ice Block Making Machine

ABSTRACT The aim of this paper is to get a best performance by an ice block/cube making machine of refrigeration with suitable time. In present day hotels, resort and bar require more ice in very less time. So, to solve this problem and control the required time to ice formation, we construct an ice cube making machine. In present days, in market this machine is available with very high cost. So we try to make it at optimum price. Ice making machine consists of four key components; the evapor...

Design and Performance Evaluation of an Ice Block Making Machine

ABSTRACT The ambient temperature of tropical countries like Nigeria is as high as 40oC during the dry season. This ultimately gives rise to increase in demand for ice which is used to reduce the temperature of water, soft-drinks as well as other uses. This increase in demand for ice block makes the design and construction of a machine which can be used for the production of ice within a short period of time in order to save energy and time imperative and a worthwhile venture. This paper prese...

Design and Construction of an Automatic Power Changeover Switch

Abstract Power failure or outage in general does not promote development to public and private sector. The investors do not feel secure to come into a country with constant or frequent power failure. These limit the development of industries. In addition there are processes that cannot be interrupted because of their importance, for instance surgery operation in hospitals, transfer of money between banks and lots more. This paper presents the design and construction of an automatic power chan...

Public Transportation: The Role Of Government And Private Enterprise

ABSTRACT Transportation is a requirement for every nation, regardless of its industrial capacity, population size or technological development. The Nigerian transport systems, right from inception, were poorly designed and are unable to scale up to meet greater demand, a design flaw which causes traffic congestion on roads, overstressed railways, faltering airfields, and mass-transport blind spots. Overall there appear to be market impediments which operate to limit the extent to which Nigeri...

Digitization of Television Broadcasting in Nigeria Review

ABSTRACT Information and Communication Technology (ICT) has opened up new and robust ways of sending and receiving information at global level. Any type of information including voice and video is sent to the diverse publics, who equally have variety of choices. Thus, the development of any nation is tied to efficient information dissemination. In Nigeria, television broadcasting started in 1959 with the establishment of the Western Nigeria Television (WNTV) by the opposition leader, Chief Ob...

The Production Of Yam Flour

ABSTRACT The project dealt on the production of yam flour from yam chips. The yams were peeled and washed, 100grams samples coded sample A to G were subjected to two different drying conditions. Some were dried using the sun drying method while the others were dried through oven drying method kept at constant temperature of 500C, sodium bi-carbonate was added to some of the samples, all these were done to obtain a flour with the best colour and texture quality. From the results obtained, it w...

The Effect Of Temperature On Hydrolysis Of Cellulose (Saw-Dust)

ABSTRACT The effect of concentration of hydrochloric acid on hydrolysis of cellulose (saw-dust) to glucose was studied on this research project and the steps obtained to achieve this project involved treatment of saw-dust (cellulose) with different concentrations of the acid at constant temperature of 80° (350k) for 30mins. This was followed by glucose analysis, some analysis or experiments were done on acid hydrolysis in order to study the effect of (HCL) acid on the hydrolysis of cellulose...

Design Of A Patient Heartbeat And Temperature Monitor Using RF

The major aim and objective of this design [of a patient heartbeat and temperature monitor using RF.] is to help the doctors and family members to keep track of the heartbeat condition of their loved ones [as well as their body temperature] in the case of an abnormality in the health condition (for those with heartbeat defects and those that run excessive high temperature beyond normal). If any varied change takes place, it is notified. This notification through RF. Channel would to take an a...

Home Control Switch Automation Using Gsm Communication

ABSTRACT The advantage of cellular communication like GSM technology is a potential solution for such remote controlling activities. GSM-SMS technology can be used to control household appliances from remote places. Remotely, the system allows the home owner to monitor and control his house appliances via his mobile phone set by sending commands in the form of SMS message and receiving the appliances status as well. This system provides ideal solution to the problems caused in situations when...

Head Loses In Horizontal And Vertical Orificemeter A Comparative Evaluation And Analyses With Apllication Of Statistical Method Of Data Reliability

ABSTRACT A comparative investigation was undertaken to determine the head loss coefficients for horizontally mounted and vertically mounted orifices using a Fluid mechanics and Heat transfer trainer developed in Nigeria. Experiments were carried out observing the procedure and the discharge of the flow of water was collected to obtain the volumetric flow rate and also read off the right and left limb of the horizontal and vertical manometers at different set points. The experimental measureme...

Design And Construction of Automatic Phase Selector

The scope of the project covers aspects like the features of automatic three phase selector, its applications, and its operations. Its advantages and its components. Finally, it covers the importance on the need of automatic three phase selector and contributions toward a greater sharing load balance and a better three phase power distribution and monitoring for domestics consumers. INTRODUCTION As the growing population of human race widens the gulf between energy supply and energy demand, ...

Design And Construction Of An Inverter Type Arc Welding Machine

The main aim and objective of this project is to design and build and arc welding machine that operates on 36vdc at variable frequency which of benefit to urban area. This reduces the weight and size of the transformer use for welding. To have an arc welding machine that is more efficient which produce neat welding. INTRODUCTION Welding is a way of heating pieces of metal using electricity or a flame so that they melt and stick together. It can simply be defined as the process of joining two...

Design And Construction Of 20 Watts Wireless Public Address System

ABSTRACT It has become inevitable that there would be communication and due to the inherent limitation of the human voice, the public address system came to being. A public address or “P.A SYSTEM” is an electronic amplification system with a mixer ,amplifier and loudspeakers, used to reinforce a given sound , e.g a person making a speech, pre-recorded music ,or message and distributing the sound throughout a venue . The voice signal is passed through a microphone , which converts the sou...
