Title: Wobble plate type refrigerant compressor having a ball-and-socket joint lubricating mechanism
Inventor: ONO TOKIHITO
IPC: F16N7/28
Filed: 1991-02-12
Granted: 1997-03-04
Abstract: A wobble plate type refrigerant compressor having a lubricating mechanism provided at a ball-and-socket joint between a wobble plate and a piston rod is disclosed.  A wobble plate type refrigerant compres-sor includes a compressor housing having a cylinder block.  A plurality of cylinders are formed around the periphery of the cylinder block and a piston is slidably fitted within each of the cylinders and is recipro-cated by a drive mechanism.  A crankcase is formed between the cylin-der block and a front end plate of the compressor housing.  The drive mechanism includes a drive shaft, a rotor fixed to the drive shaft and a wobble plate disposed on an inclined surface of the rotor.  The piston rod connects the wobble plate to the piston.  A ball at one end of the rod is received in a socket formed at the wobble plate to form a ball-and-socket joint.  A hole is formed at the wobble plate to link one end surface of the wobble plate to the friction surface of the ball-and-socket joint.  A pair of grooves extending from one opening of the hole and terminating near the outer periphery of the wobble plate are formed at one end surface of the wobble plate.  Thereby, the lubri-cating oil adhering to one end surface of the wobble plate is effectively led to the friction surface of the ball-and-socket joint.

Title: Fixing device for image forming equipment
Inventor: ARIYAMA KENZO
IPC: G03G15/20
Filed: 1991-03-22
Granted: 1996-04-02
Abstract: A fixing device applicable to image forming equipment and cable of controlling the amount of silicone oil to be applied to a heat roller. Silicone oil is applied to the heat roller via applicator felt, a second application roller and a first application roller.

Title: Multi-hull boat
Inventor: TOLLET DANIEL
IPC: B63B1/10
Filed: 1991-05-06
Granted: 1996-07-16
Abstract: A multi-hulled boat has at least three hulls, with the outside hulls extending forward beyond the central or inside hull or hulls.  The hulls are tapered with a cross-sectional configuration that increases in size front to rear, thus forming a channel or tunnel between adjacent hulls which decreases in cross-sectional size front to rear.  Air entering the tunnels is compressed, thus imparting a lifting force to the hulls lifting the hulls partially out of the water to decrease the hydraulic drag on the hulls.  The hulls have identical cross-sectional areas at identical transverse planar sections thereof.  The bottom of each hull is flat and inclined at an angle with the horizontal.  The hull bottoms join the hull sides at a chamfer which increases in size front to rear.  Shutters or flaps may be used to partially or fully close off the tunnels between the hulls to control airflow or to trap water-borne material to be collected and recycled.

Title: Fault detection apparatus for a transformer isolated transistor drive circuit for a power device
Inventor: SCHNEIDER ERIC DUANE
IPC: H03K17/082
Filed: 1992-06-17
Granted: 1997-10-28
Abstract: A protection circuit which electrically isolates logic level and high-side circuits and detects high side power device fault conditions at the isolated, logic level side of the circuit.  When an overvoltage or overcurrent condition occurs at the power switching device, a protection circuit disables the conduction of current through the current carrying terminals of the switching device, preventing damage from occurring to the device.  Activation of the protection circuit effects an increased current flow in the secondary and primary coils of the isolation transformer between the low side and high side elements.  Voltage at the primary coil of the isolation transformer is monitored by low level circuitry to detect the rise in current, indicating a fault to the system controller upon detection.

Granted: 2001-07-17
Abstract: A driving connection between a hollow camshaft (1) and its driving shaft (5) located within it, the axes (3, 8) of these two members being parallel but laterally displaceable to vary the characteristics of rotation of the camshaft in response to constant-speed rotation of the driving shaft. The camshaft supports a slideway (11) in which moves a slider (12) which makes a rotary joint with the end of an arm (15) carried by the driving shaft. The geometry of the arm is such that the centre of rotation (18) of the rotary joint lies within the outline of the periphery of the driving shaft (5) when viewed along its axis (8), thus promoting radial compactness. The essential component of the arm may be an item (15) of crescent-shaped cross-section, the concave surface (19) of the crescent registering with the surface of the driving shaft.

Title: Low nox aspirated burner apparatus
Inventor: CHMIELEWSKI KONRAD G
IPC: F23C3/00
Filed: 1993-04-28
Granted: 1998-06-16
Abstract: A low NOx burner assembly of a fuel-fired heating appliance is supplied with an air/fuel mixture having a substantially less than stoichiometric  air-to-fuel  ratio.    The  air-rich  mixture  is partially combusted to create primary combustion products disposed within an open inlet portion of a combustor structure having a catalytic converter operatively positioned within an open outlet portion thereof spaced apart from its open inlet portion.  A flow of  aspirating air is  introduced into the combustor structure between the inlet and outlet portions thereof.  The aspirating air mixes with the primary combustion products, cools them, and flows with  them  outwardly  through  the  catalytic  converter.    This essentially completes the combustion of the remaining fuel within the  cooled  primary  combustion  products,  and  does  so  at  a temperature not appreciably greater than the initial combustion flame temperature to thereby substantially reduce NOx emissions without the use of flame quenching techniques.  The burner assembly is representatively illustrated as being incorporated in several types of forced air heating furnaces, but could also be used in other types of fuel-fired heating appliances such as boilers and water heaters.

Title: Process for the production of ethylene and mixtures containing ethylene
Inventor: VISWANATHAN KRISHNAN
IPC: C07C5/327
Filed: 1991-11-27
Granted: 2002-02-19
Abstract: The present invention provides an efficient process for the production of ethylene or a mixture of ethylene and vinyl chlo-ride, in which some 1,2-dichloroethane (EDC) may also be produced, by reacting chlorine with ethane. The process is character-ized by a conversion of ethane per pass through the reactor of at least about 50 %, and a combined molar yield of ethylene and vinyl chloride of at least about 80 % based on the ethane consumed. In accordance with this invention, there is provided a process for preparing ethylene or a mixture of ethylene and vinyl chloride by the reaction of ethane and chlorine which comprise: a) pro-viding a stream of ethane feed gas and a stream of chlorine feed gas; b) preheating either said ethane stream only or both said ethane and chlorine streams; c) thoroughly mixing said ethane and chlorine feed gases within about one second and at a molar ratio of ethane to chlorine of at least about 0.9:1.0; d) said preheating being sufficient to enable the resultant mixture to have a temperature above the free radical formation temperature for chlorine; and e) permitting said ethane and chlorine in said mixture to react so that the reacted mixture has a temperature between about 600 °C and 800 °C; whereby the combined molar yield of ethylene and vinyl chloride is at least about 80 % of the ethane reacted.
