ABSTRACTThis system “MICROCONTROLLER BASED AUTOMATIC HAND DRYER SYSTEM” comprises of many modules which are: The Sensor/Input Unit, Microcontroller Unit and the Output Interface. The sensor detects when the hand approaches the nozzle. Once the approaching hand is detected, the hand dryer produces a very hot to dry the hand as well as displaying “busy” on the display unit of the design. Once the hand is removed, the hot air automatically stops and the display unit displays “idle”. ...
INTRODUCTION This project presents the design and construction of a computer based program used to control office appliance. It is based on a Graphic user interface (GUI) programming language (Visual Basic 6.0), Parallel Port Interactive Mode, Opto-Coupler Isolation of the computer from the appliance to prevent damage to the system should a fault develop in the appliance. The implementation was based on the interaction of the computer with electronic appliance via the 25 Pin Centronic...
This work is based on automatic changeover switch. If there is failure in main power supply it will automatically change to auxiliary power supply such as generator. This project is based on electromechanical changeover with the use of magnetic contractors, relay,and circuit breaker.
ABSTRACT This project involves the development of a console that allows multiple inputs (3 inputs) and a single output to a screen through the use of software. The micro controller which serves as the ‘heart’ of the hardware was encoded using C programming language. These lines of code enable the micro controller to switch to the selected signal when the remote is pressed or one of the buttons is pushed.
Abstract Petroleum based detergents are neither soluble nor biodegradable; they are so stable such that when they flow into the soil, sewer or surface waters, they remain unchanged, resisting conversion into less complex and more soluble substances. In this work methyl ester sulphonate (MES) was produced by transesterification followed by sulphonation of ricinoleic acid, a main constituent of castor oil. A detergent was produced from transesterification followed by sulphonation of castor oil ...
ABSTRACT Deregulation is the removal or simplification of government rules and regulations that constrain the operation of market force. In course of studying the effect of deregulation, various economic model will be applied to data gotten from the Nigerian National Petroleum Corporation NNPC for efficient and workable economic policy that will bring a sustainable development to both the sector and the country as a whole. This work analyzes the various implications removal of subsidy wil...
ABSTRACT Industrial waste water treatment covers the mechanisms and process used to treat water that have been contaminated in some way by anthropogenic industrial or commercial activities prior to its release into the environment or its re-use. Water is a natural and inorganic solvent with the composition of hydrogen and oxygen only (H20). When there is addition of other organic or inorganic, substances (high levels of nutrients, nitrogen and phosphorous) in water which may come as a re...
ABSTRACT The production and analysis of “Ngu” extract for temperature and water requirement for leaching of caustic alkali is the basic objective of this project. The production was carried out by using unit operations and also using the female inflorescence of a palm fruit (Eleasis Guineesis) as raw material. The female inflorescence of palm fruit was size reduced from original dimensions to maintain particle size characteristics. The size reduced bunches were dried at room temper...
ABSTRACT This project “production of plane mirror using local raw material” is meant to study the possibility of producing plane mirror using sand rich in silica as its major local raw material.Plane mirror is produced by casting one side of a sheet glass. Presently in Nigeria, sheet glass is not used easily produce and as such, the local raw material used in the in the production of plane mirror in this product backing paint. The facilities for the production include spraying gu...
ABSTRACT This project is aimed at producing black and brown polish of good quality. For clearity, polish is a substance rubbed on the surface of materials to make them smooth and shiny. Polish has being of immense importance in protecting leather surfaces and enhancing their beauty.To produce a standard polish, hard waxes such as carnduba wax, candelhla wax and palm wax; semi-hard waxes which include, paraffin wax and ozokerite; solvents like tupentine and naphtha; dyes and dryers are esse...
ABSTRACT This report aimed at determining the presence and removal of mercaptan sulphur in kerosene using colour indicator method. It is known that impurities such as free sulphur, sulphur dioxide, mercapters, funing materials etc. are found in petroleum products. Consequently,absorbents like molecular sieve, calcium oxide and even activated carbon could be used to trap these impurities, thereby making the product impurity free.The afficac of the absorption using calc...
ABSTRACT Interface on petroleum product in multi-purpose pipeline system refers to as the zone of demarcation between two products where mixing occurs. Generally, interface is a boundary layer, so the boundary between two products when they are pumped in succession is known as interface.In Nigeria Petroleum Industries like NNPC (PPMC) make use of multi-purpose pipeline system. This is where interface comes in petroleum products. Interface as defined above plays a lot of economics impor...
ABSTRACT Blender is an electric machine for size reducing soft food or liquid mixture. Blender is some time called liquidizer consists of a glass jar or jug containing a steel blade assembly at the base driven by a small electric motor. Construction of blender was done based on the principle of size of reduction using electric motor as the major driver force. During the construction of blender, we adopted different stages which includes: i.The production of preliminary drawings with deta...
ABSTRACT Adhesive is a substance that holds materials together by surface attachment, while wood adhesive is a substance that is used to hold plywood for furniture works. This substance is essential and has universal applications. Thus the aim of this research work is to produce it using cassava starch as a base binder. Starch is also used in industries to produce ethanol and glucose for textile industries, laundry and paper adhesive industries.It is of great importance to paper, wood and fu...
INTRODUCTION Planned maintenance apart from programming inspection, should include monitoring, logging, periodic checks and tests of system as to guarantee correct day-today hitch free functioning and control of “closed circuit” water systems to maintain trouble-free operations.This first requirement for any maintenance system planned or otherwise is to compile an inventory of all plants and equipment to be maintained. Besides, additional information must be readily obtained from the manu...
