Title: Positive displacement pump with rotating reciprocating piston and improved pulsation dampening
Inventor: GERLACH RICHARD C
IPC: F04B7/06
Filed: 1991-09-25
Abstract: POSITIVE DISPLACEMENT PUMP WITH ROTATING RECIPROCATING PISTON                ABSTRACT OF THE DISCLOSURE    A positive displacement pump especially designed for home use comprises a crankcase housing and a cylinder block joined thereto, the cylinder block containing a cylindrical bore whose longitudinal axis is at a predetermined angle relative to the longitudinal axis of the pump's drive shaft journaled in the crankcase housing.  A piston having a central longitudinal bore formed inward from one end thereof and which includes a timing window extending through its side surface, is fitted into the cylindrical bore and coupled to the drive shaft by a pin which is journaled in a spherical bearing.  A suction port is formed through the wall of the cylinder block on one side surface thereof and on the opposite side surface, 180° away, is a high pressure discharge port.  When the pump is driven, the piston both rotates and reciprocates causing the timing window in the piston to sweep by the inlet or suction port where a charge of liquid at low pressure is allowed to enter the hollow piston.  As the piston rotates, the timing window moves to a point where it is ultimately in line with the discharge port when the piston is at a top dead center position.  By canting the pin of the piston relative to its longitudinal axis compensation for the unequal hydraulic forces acting in the transverse direction on the piston results.   An improved lubrication system incorporating grease as the lubricant is also employed.

Patent CA-2069214-A1 (CA)
Inventor: WHITE CRAIG W
IPC: B60R21/16
Filed: 1992-05-22
Abstract: An air bag firing circuit comprises a firing path which includes in series a safing sensor, a squib, and a FET operated under microprocessor control  in response to the output  of  an  electronic  crash  sensor.    A  power  supply maintains a known voltage across the firing path sufficient to explode the squib upon simultaneous "closure" of both the safing sensor and the FET operated by the microprocessor in response to crash sensor output.  Normally, upon detection of a failure in the electronic crash sensor,  its supporting electronics,  or the FET actuated in response thereto,  the microprocessor reconfigures the firing threshold of the safing sensor, as by applying a current to its integral test coil to increasingly bias the sensor's inertial mass away from its switch contacts.  However, if a failure of the safing sensor is detected, reconfiguration of its threshold is inhibited notwithstanding the failure of other circuit components to prevent inadvertent deployment of the air bag.   Once the safing sensor is reconfigured, the microprocessor turns on another FET to pull one side of the squib to ground, thereby removing the inoperable FET from the firing path and ensuring continued protection of the vehicle passengers until  the sensor is serviced or replaced.

Abstract: ABSTRACT OF THE DISCLOSURE    A method is disclosed for extending an extender probe to produce a single stranded polydeoxynucleotide that is free of unreacted extender probe and has two segments that are non contiguous and complementary with each other.  The method comprises the steps of (1) providing in combination (a) a polynucleotide having two non-contiguous, non-complementary nucleotide sequence S1 and S2 wherein S2 is 5' of S1 and is at least ten deoxynucleotides long, (b) an extender probe comprised of two deoxynucleotide sequences, wherein the sequence at the 3'-end of the extender probe (EP1) is hybridizable with S1 and the other of the deoxynucleotide sequences (EP2) is substantially identical to S2 and (c) means for modifying the 3'-end of extender probe that does not  hybridize with the polynucleotide and (2) extending the extender probe along the polynucleotide wherein extender probe not hybridized to the polynucleotide become modified at its 3'-end.     A method is also disclosed for forming a polynucleotide sequence complementary to a single stranded target polynucleotide sequence ("target sequence"). In the method a polynucleotide primer having a 3'-terminus comprised of a nucleotide monophosphate, which has at least one phosphate-sulfur bond, is hybridized to the 3'-end of the target sequence.  The polynucleotide primer is extended along the target sequence and the extended polynucleotide primer is then dissociated from the target sequence. The method finds particular application in the area of nucleic acid amplification. 12492.01                     27410/27640-FF
