Patent CA-1082759-A (CA)
Inventor: CARL DOUGLAS E
IPC: G05D23/275
Filed: 1979-10-12
Granted: 1980-07-29
Abstract: ABSTRACT OF THE DISCLOSURE            The invention consists of an electrical heating apparatus which provides for controlled fuel substitution in a heating system, particularly a forced-air central heating system.  The electrical heater assembly is mounted in the system and a device is provided to select electricity as the heating fuel when off-peak periods in electricity demand occur.          Since the cost of producing electrical energy during these off-peak periods is well known to be lower than during peak period times, the user of the invention will realize savings in total heating fuel costs through the substitution of electrical energy for the primary fuel, such as oil, wherever the off-peak price of electricity is sufficiently lower than the energy-equivalent price of the primary fuel.  Where fossil fuels, principally oil, are used as the primary heating fuel, the invention will further act to conserve increasingly scarce and increasingly costly fuel supplies.  Since the electrical heater is not used during peak demand periods, no increase in generating capacity is required for the invention to be utilized on a mass scale.

Title: Oil reclaimer and muffler assembly and system
Inventor: GEORGE PAUL R
IPC: B01D45/16
Filed: 1979-12-04
Granted: 1982-05-18
Abstract: ABSTRACT         A vacuum system can include a vacuum pump, means to provide a flow of lubricant to the vacuum pump, and an oil reclaimer and muffler assembly to remove oil that becomes entrained in the gas stream leaving the pump and to permit such oil to be resupplied to the means providing the flow of lubricant to the pump.  The oil reclaimer and muffler assembly includes an outer casing having an inlet opening for the gas stream from the vacuum pump.  Wall means are provided within the outer casing to form a passageway to circulate the gas stream adjacent the inner wall of the casing.  Entrained oil and water from the gas pump are collected on the inner walls of the assembly and flow under the influence of gravity to a collection pipe at one end of the assembly.  The inner wall means also forms a passageway from adjacent the bottom of the assembly to its top from which the cleansed gas passes.  The reclaimed oil and water that are collected within the assembly accumulate in an oil reservoir from which the collected oil can be withdrawn for use in lubricating the vacuum pump.

Abstract: ABSTRACT       A gas fired barbecue grill is provided with an electric spark type automatic gas igniter mounted on the bowl or basin of the grill in such a manner that only a sparking plug extends into the bowl while electrical and mechanical components for energizing the sparking plug are suspended outside of the bowl.  Specifically, a piezo-electric gas igniter has an exterior box or casing bolted to the basin containing a manually actuated hammer impar-ting a capsule containing a steel and metal sandwich to develop a voltage carried to a sparking plug on the box which projects into the basin close to the burner head of the grill for igniting the gas.  The box is insulated from the basin and is kept cool by air surrounding the basin.          The mounting accommodates separate or simultaneous ignition of a plurality of burners and the interior of the bowl is free from wires or the like components which might be damaged from the heat or pollution inside the basin.  The same bolts mounting the exterior box also mount an interior gas collecting cage or box around the plug to expedite ignition.

Abstract: RCA 73,530 Abstract A high sensitivity voltage comparator circuit, suitable for integration in monolithic form is disclosed. First and second p-channel field effect transistors, FETs, are arranged as a first cascode amplifier between a relatively positive supply potential and an output node. First and second n-channel FETs are arranged as a second cascode amplifier similar to the first which is connected between a source of relatively negative supply potential and the same output node.  Bias potentials are selectively applied to each of the gate electrodes of the FETs to balance the composite amplifier concurrently with application of a reference signal via input coupling capacitors to the amplifier inputs.  Subsequently signal potential is selectively applied to the amplifier inputs, to the exclusion of the reference potential.

Abstract: The danger of explosion due to decomposition of high-pressure industrial process gases, such as ethylene, is reduced by maintaining in an inert atmosphere at least part of an evacuation system included between a pressurized vessel within which the decomposition may take place, on the one hand, and the atmosphere, on the other. The evacuation system to the atmosphere for the gases contained in the high-pressure vessel, includes (1) an evacuation pipe adjacent to the vesel; (2) a safety means separating the evacuation pipe from the vessel; (3) a sealing means located in the evacuation path of the gases and occupying the entire cross-section of the evacuation pipe; (4) a first gas supply circuit connected by a pipe to that part of the evacuation pipe that is located between the safety means and the sealing means, and means for the first supply pipe to control the volume of gas supplied by the first supply circuit; and (5) a second gas supply circuit connected by a pipe to the sealing system, and means for the second supply pipe to control the volume of gas fed by the second supply circuit. The apparatus is useful for the recovery of decomposition products for the purpose of averting atmospheric pollution, as well as for reducing the risk of explosion.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a trench shoring assembly which includes a pair of spaced-apart side walls for vertical disposition within a trench. Spreader pipes and spreader collars interconnect the side walls and allow limited pivotal movement between the side walls.  Each side wall includes outer and inner metal plates connected to a horizontally extending hollow top beam which extends longitudinally along the top of the side wall, two intermediate beams parallel the hollow metal beam and a bottom beam.  A hardwood insert is disposed within the top beam to prevent the collapse of the hollow metal beam. A number of hollow beams extend perpendicularly to the horizontal beams and ribbed members extend perpendicularly to the horizontal beams.  The side walls of the assembly have a tapered bottom portion which defines a triangularly shaped pointed lower extremity extending between the ends of the bottom portion. A metallic bar is disposed at the pointed lower extremity and extends between the ends of the bottom portion and protects the bottom of the side wall against abrasion.  A U-shaped member is welded to the main frame, and, in turn, a spreader collar is welded to the U-shaped member so that a force applied to the spreader collar is transferred directly to the main frame.  Each spreader pipe spaces the side walls apart between two spreader collars to which the spreader pipe is attached by spreader pins.  Lifting rings are slidably attached to the spreader pipes for lifting the assembly.  A plurality of flanges extend from a spreader pipe and are connected by locking pins to mating flanges which extend from another spreader pipe of another vertically stacked trench shoring assembly.

Abstract: ABSTRACT OF THE DISCLOSURE          A multi-stage evaporator is used to remove water from the extracted distillation or stripper tower bottoms recycled as quench liquid to the quench tower of an acrylo-nitrile purification and recovery system.  This results in a significant decrease in the amount of waste quench tower bottoms produced by the system.  Use of a multi-effect evap-orator represents a significant energy savings as compared with other techniques for decreasing the water content of the recycle stream.
