Patent CA-2153274-A1 (CA)
Title: Power-out reset system
Inventor: HOANG CHINH L
IPC: G01R31/40
Filed: 1995-07-05
Abstract: A power-out reset circuit includes reference voltage and current generators to generate a reference voltage and a reference current which are essentially independent of temperature variations over a useful temperature range, a delay/disable circuit, over and under voltage detectors and output logic circuitry.  This circuit detects when the voltage level of a supply voltage source (+VDD) exceeds preselected limits.  The reference voltage, which is related to the silicon band gap voltage, is connected to a first input of a comparator of each of the voltage detectors.  The reference current, which is derived from the silicon band gap voltage, is connected to a current source of each of the detectors.  Each detector has a hysteresis circuit which changes the point at which the comparator switches in the event that +VDD crosses into or outside of a preselected operating range.  The delay/disable circuit ensures that the reference voltage is stable before the voltage detectors are activated, and that the voltage detectors are disabled when the supply voltage source falls below a minimum value which causes the reference voltage to be invalid (i.e., to be outside the preselected operating range.  Outputs of the comparators are coupled to the output logic circuitry.  The output logic circuitry includes a two input EXCLUSIVE OR logic circuit, a delay circuit, a two input OR logic gate, a transistor, a two input NOR logic gate, and an inverter.

Title: Ground source heat pump system comprising modular subterranean heat exchange units with multiple parallel secondary conduits
Inventor: RAWLINGS JOHN P
IPC: F24V50/00
Filed: 1994-02-08
Abstract: An improved ground source heat pump system wherein the subterranean piping installation comprises modular heat exchange units. Each modular heat exchange unit (36, 38, 40) comprises a plurality of parallel secondary or branch conduits (54, 56, 58, 54A). The use of multiple parallel secondary conduits significantly increases the heat exchange capacity of the system. Because of the increased efficiency of such a system, less piping is required, which in turn reduces the cost of labor and materials to install such a system and the area of land mass required to contain it. Moreover, because the heat exchange units are modular, they can be prefabricated at a remote site and then conveniently transported to construction  site and installed much more quickly than the extended lengths of conventional piping.

Title: Sealing apparatus for packaging containers
Inventor: OHLSSON PER
IPC: B31B50/66
Filed: 1994-07-15
Abstract: A sealing apparatus for packaging containers includes an anvil (23) for supporting a sealing fin portion (21), a horn (35) composed of a columnar portion and a converging portion (35b), and means for pressing said sealing fin portion (21) against the anvil (23) through the tip of the horn (35) and for transmitting ultrasonic vibration to the sealing fin portion (21).  Ultrasonic vibration is transmitted to the packaging material through the horn (35) so that each pair of opposing sealant layers is fused and sealed.  In addition, means for absorbing ultrasonic vibration is disposed between the tip of the horn (35) and an edge portion (25) of the sealing fin portion (21) so that ultrasonic vibration is absorbed.  When ultrasonic vibration is transmitted to the sealing fin portion (21), the sealing fin portion (21) is excited to transmit the vibration toward the edge portion (25).          However, since the ultrasonic vibration is absorbed by the means for absorbing ultrasonic vibration, the ultrasonic vibration is not transmitted to the edge portion (25).  Accordingly, it is possible to prevent the generation of dust from an end surface of the paper substrate which is exposed at the edge portion (25) of the sealing fin portion (21) .

Filed: 1996-02-09
Abstract: The method of fabricating a tank connector assembly comprising the steps of first providing a metal spud member having an internally threaded portion and a cylindrical wall portion. Producing a sub-assembly comprised of an insert member having an internal groove therein and made from a polymer material and an expandable band member positioned in the groove. The next step is to assembly the sub-assembly of the insert member and expandable band member with the spud member. Thc sub-assembly is positioned inside the cylindrical wall portion of the spud member. The next step is to apply an expansion force to the expandable band causing the band to deform slightly and thereby force the insert member into tight sealing contact with the depending wall portion of the spud member. The metal spud member is welded in an opening in the wall of a steel tank. A polymer material is introduced into the interior of the steel tank and the tank is then subjccted to a rotational casting movement in the presence of heat to cause the polymer material in the tank to be uniformly distributed over the internal surface of the tank. The heat applied during the rotational casting step serves to cause the inner tank to become bonded to the insert member.

Title: Prenatal diagnosis by isolation of fetal granulocytes from maternal blood
Inventor: BIANCHI DIANA W
IPC: C12Q1/6804
Filed: 1994-09-23
Abstract: A method for detecting presence or absence of a nucleic acid of interest in fetal nucleic acid derived from a sample of peripheral blood obtained from a pregnant woman is described.  The method involves obtaining a sample of peripheral blood from a pregnant woman, treating the sample of peripheral blood such that fetal nucleic acid present in fetal granulocytes is made available for detection and detecting presence or absence of a nucleic acid of interest in the available fetal nucleic acid. The proportion of fetal granulocytes present in the sample of peripheral blood can be increased relative to the sample of peripheral blood forming a sample enriched in fetal granulocytes prior to the detection step. The nucleic acid of interest can be detected by treating the peripheral blood sample such that fetal granulocytes nucleic acid present in the sample is made available for hybridization with a nucleic acid probe and subsequently contacting the available fetal nucleic acid with a nucleic acid probe hybridizable to a nucleic acid of interest under hybridization conditions.  The presence or absence of hybridization between the nucleic acid probe and the nucleic acid of interest is detected as an indication of the presence or absence of the nucleic acid of interest in the fetal nucleic acid.

Title: Coiled tubing deployed inflatable stimulation tool
Inventor: DECKER KENNETH L
IPC: E21B23/00
Filed: 1996-05-02
Abstract: A resettable well stimulation tool is lowerable into a well bore on a length of tubing through which pressurized fluid may be forced into the tool to inflate a packer portion carried by the tool and then discharge a stimulation fluid into a portion of the well bore sealed off by the packer portion.  During the inflation cycle of the tool pressurized fluid is forced downwardly into an annular tool body inflation chamber that communicates with an inflatable packer carried by the tool body.  A perforated tube member coaxially carried in the inflation chamber serves to vertically distribute the inflation pressure along the length of the packer and assure its even inflation.  In a straddle packer embodiment of the tool inflation and stimulation passages extend internally through the tool and are sealingly separated by an internal crossover structure, with the inflation passage being in communication with upper and lower packer members. The internal inflation  passage  eliminates   the  previous   necessity  of communicating the upper and lower packers with inflation tubing externally  coiled around  the  tool  body.    A  longitudinally intermediate portion of the tool body has a telescoping expansion joint portion to compensate for the longitudinal forces exerted on the body by inflation of the packers.   The expansion joint is biased, by both mechanical spring pressure and internal fluid pressure, toward a retracted position thereof.
