CONSTRUCTION OF A BATTERY CHANGER USING SILICON CONTROLLED REGULATOR (SCR)

ABSTRACT  The practical importance of a battery charger in today world cannot be over emphasized. This is so as those batteries accumulators are immensely needed by out auto mobile and in science laboratories. This thesis describes the methodical approach to the design and construction of  any battery charger. However the procedure fro developed cover the construction  of battery charger for battery sizes ranging from 6 voltage to 24volatge (heavy duty) batteries. The prototype of a batter...

CONSTRUCTION OF 150 WATTS 162 AUDIO LOUDSPEAKER

ABSTRACT  Audio loudspeaker (output transducer) is on of the most essential and powerful device used in telecommunication system. This is device capable of converting electrical signal into sound and vice versa. It is made up of few time of non-magnetic wire wound on a light cylindrical former that is mounted so that it can move freely insides the magnetic field of a strong permanent magnet. The speaker cone it attached to the voice coil and attached with a flexible mounting to outer ting of...

THE FABRICATION OF A SINGLE FACE PRESSURIZED KEROSENE COOKER

ABSTRACT  This project is concerned with the fabrication of as a single face pressurized kerosene cooker. The report shows the possible way in which the above mentioned can be designed, fabricated and maintained.  Its also shows the strength and properties of the materials it is made of.  Defects of the equipment can come through inability to maintain and inability to use well.  It can be due to irregular cleaning of pressurized parts, exposure to rain, moisture and sunlight as well as i...

THE CONSTRUCTION AND FABRICATED OF A MOBILE DEEP FREEZER

ABSTRACT This work on the construction and fabrication of a mobile deep freezer revolves around the concept of refrigeration. The concept of refrigeration revolves around the reverse Carnot cycle. This is  a cycle involving isentropic expansion (at the throttling valve), isothermal expansion (at the evaporator), isentropic compression (at the compressor) and isothermal compressor ( at the condenser) Compression raises the temperatures of the refrigerant above that of its natural surrounding...

REPAIR AND REHABILITATION OF A FAULTY DEEP FREEZER

ABSTRACT  Mechanical Engineering Department of the named Institute has many non – operational malhiues. Sequel to the fact, maintenance was poorly excuted which resulted to the breakdown deep freezer. Quality and effectiveness of machine maintenance were well observed. Also, a minimized maintenance and a highly successful  repair was adopted. In other words during the repair and rehabilitation of the facility Deep Freezer, appropriate tools, cost and  quality of materials were well...

Design And Construction Of Metallic Bookshelf

ABSTRACT Books are used recoding of what is happening or event that has already taken place which can be storing information it is useful and for the information that such books contained not to cost it support to be properly kept and these can be done when those books are kept in a cool dry place and a place free from rodents and insects attacked  Therefore, our contribution to proper storage of books is the deigns and construction of a metallic bookshelf that will be economically cheap an...

AUTOMOBILE MOTOR VEHICLE CONSTRUCTION

ABSTRACT This work is an attempt evolve a quicker and easier method of achieving Transportation. This will no doubt save considering human labour and time wasted involved in traditional manual method of transportation. To achieve this, preliminary experiment was first carried out to determine the optimum speed of the motor vehicle. Various design alternative s for achieving the design solution were sythesized and a choice of an economic method which would satisfy the objective was made. Base...

ABSORPTION OF PALM OIL WITH SYNTHETIC ADSORBENT (COAL)

ABSTRACT This project was Carrie lent using sub-bituminous coal and crude palm oil.  The degree of bleaching of the palm oil was monitored with a spectorphoto meter.  The coal was collected in a lump from the mine.  It air-chiecl  to removed the   moisture content and thereafter, size reduced to a small particle size foe effective activation. The activation process was carried out in a fume cup board and phosphoric acid was used as an activated agent. In the treatment of palm oil, sodiu...

Water Purifcation Unit

ABSTRACT Water Purification Unit or filtration unit is designed in way that it will give a nice result. Like in our filtration, we have sand and carbon filter that were responded to separate the suspended solid particles, odour  and taste of the water, which will give a very nice filtered water at the end of the filtration. This unit has no chemical engineering operation, but a physical separation process that will separate the dead micro organisms and the task, colour odor of the water.  ...

THE USE OF LOCAL PIGMENTS AND EXTENDERS FOR FORMULATION & PRODUCTION OF EMULSION PAINT

ABSTRACT The major aim of this project research work is to produce emulsion paint from locally sourced pigment & extenders. The materials used for the production was of local source. The major raw materials used for the production of the emulsion paint: water, titanium iv oxide, calcium carbonate, kaoline, calgon, natrosol, biocide P.V.A, ammonia, deformer (Ginap) kerosene, yellow iron oxide and red iron oxide. Emulsion paint of two (2) samples was produced, and calcium carbonate locally obt...

THE REFURISHMENT OF FLUID FLOW DEMONSTRATION UNIT

ABSTRACT The refurbishment of the fluid flow demonstration unit was carried out in the Chemical Engineering pilot plant laboratory of the Institute of Management and Technology Enugu. The refurbishment process was carried out to ensure adequate functioning of the unit, to allow the continuous use of equipment in the pilot plant, so that student would use it in understanding the nature of the flow of fluid through pipe lines, these process was also for the development of the knowledge of ever...
