Title: Downhole pump
Inventor: MENDEZ LUIS
IPC: E21B23/08
Filed: 1990-01-19
Abstract: DOWNHOLE PUMP                   ABSTRACT OF THE DISCLOSURE         A downhole pump is provided having characteristics that permit it to be installed in a subterranean well in order to pump well fluids at a substantial pressure to operate a downhole tool, such as an inflatable packer.  The pump is mechanically driven by motor means whose diameter permits insertion through the well and whose output characteristics are suitable for driving the pump means.  A single mounting bracket supports the motor means in a housing and prevents counter rotation of the motor stators.  The motor means are immersed in a clean fluid inserted at the well surface and the clean fluid is maintained at the well hydrostatic pressure by a compensating piston.

Title: Cryogenic energy motor process
Inventor: SCHLOENDORF DELMER
IPC: B60K8/00
Filed: 1990-01-22
Abstract: ABSTRACT            Many motors and mechanical devices are powered by compressed air but are stationary due to the dependance to the air compressor.  Most other motor vehicles and mechanical devices are dependant on internal combustion type motors which cause a major pollution problem as do electrically powered vehicles and the batteries of such have a long recharging time. I have found that the use of a thermal tank of cryogenic liquid which flows to a vaporizer then expands greatly in volume giving us an increased volume of energy.  The use of this process can be used to power mechanical devices such as motor vehicles.  It is pollution free and returns the gas (air) back to the atmosphere.
Patent CA-2008700-A1 (CA)
Title: Hybrid seed production
Inventor: BRIDGES IAN G
IPC: C12N15/81
Filed: 1990-01-26
Abstract: Male sterility is imparted to a plant by a cascade of gene sequences which expresses a protein which disrupts the biosynthesis of viable pollen.      Expression of the disrupter protein is restricted to male parts of the plant by an upstream promoter sequence which is specific to male flowers, the male specific promoter being under control of an operator sequence. The cascade also includes a gene encoding a repressor protein specific for that operator. Expression of the repressor protein is under control of a chemically inducible promoter which is inducible by the application to the plant by, spraying or like process, of an exogenous chemical. In the absence of the exogenous chemical inducer, no repressor protein is expressed, resulting in expression of the disrupter protein and, consequently, male sterility. Fertility may be restored to the plant, when required for maintenance of the line, by spraying with the inducer, resulting in expression of the repressor which binds the operator and inhibits expression of the disrupter protein.

IPC: F16J15/02
Filed: 1990-07-26
Abstract: Abstract An annular seat ring in an engine has a metallic body located between the upper surface of a cylinder head retainer and the lower surface of the cylinder head flange to limit the wear thereof and seal between them.  A first annular seal groove in the seat ring upper side is spaced radially inwardly from the outer side of the seat ring and radially outwardly from the inner side of the seat ring. A first elastomeric seal member disposed in the first seal groove has a volume less than the volume of the first seal groove.  A second annular seal groove in the seat ring lower side is spaced radially inwardly from the outer side of the seat ring and radially outwardly from the inner side of the seat ring.  A second elastomeric seal member disposed in the second seal groove has a volume less than the volume of the second seal groove.  The seal members have projecting portions which block the flow of hot lubricating oil between the head retainer and the head flange.  The seal members are mechanically interconnected by connectors, formed integrally with the seal members, which extend through openings in the metal annulus.  A chemical bond, although optional, is not necessary.  The mechanical bond is a positive bond and is not subject to the inherent difficulties of chemical bonding.

Patent CA-2030144-A1 (CA)
IPC: H04N9/73
Filed: 1990-11-16
Abstract: 64 regions are set on an image sensed picture of a video camera, where each evaluating values rij, bij, and yij are obtained by averaging color difference signals R-Y and B-Y and luminance signal Y obtained from an image sensed signal over 1 field period for each region.  When determination is made that luminance evaluating value yij out of these evaluating values exceeds a predetermined value, the color evaluating values of the corresponding region are attenuated by a predetermined amount, in producing gain control signals regarding color difference signals.  As a result, the effect of an object of high luminance towards white balance adjustment is reduced.

Title: Gas separation apparatus
Inventor: SADKOWSKI PIOTR J
IPC: B01D65/02
Filed: 1991-01-18
Abstract: ABSTRACT               GAS SEPARATION APPARATUS   A membrane gas separation apparatus, typically for separating air, includes a gas separation all 14 containing an array of membranes in the form of hollow fibres 18.  The cell 14 has a first gas port 16 and a second gas port 20. Flow of gas to and from the ports 16 and 20 is controlled by a four-port, two-position valve 12.  In one position, the valve 12 admits incoming air to the port 16 and allows product nitrogen to flow out of the port 20.  In the other position the roles of the ports 16 and 20 are reversed and hence the direction of flow of the gas is reversed.  During prolonged operation, there is a tendency for contaminants to affect disproportionately the feed gas inlet and of the membrane fibres 18.  By periodically changing the position of the valve 12, different ends of the membrane fibres 18 are presented to the feed gas, and thus the operating life of the membranes 18 is lengthened.

Title: Non-resealable dispenser cap construction
Inventor: STULL GENE
IPC: B65D47/12
Filed: 1991-03-21
Abstract: The invention relates to a non-resealable dispenser cap construction having an elongate tapered, stepped hollow spout member with an exterior shoulder intermediate its ends, and a discharge orifice. A closure cap member having a transverse closure wall is mounted on the spout member with the wall engaging and closing over the discharge orifice. For such condition the closure wall is distorted and biased by engagement with the wall of the orifice. One of the members is formed with two opposite frangible tabs which overlie and are permanently attached to the other member. Each tab has a zone of weakness which ruptures under opposing rotative forces applied to the members. Removal of the cap member exposes the orifice. Re-sealing of the cap member on the spout member is prevented by a lack of retentive cooperable parts on the members.

Inventor: TANAKA MUTUO
IPC: G08B25/08
Filed: 1991-08-09
Abstract: A monitoring system has a sensor, a video camera, at least two MODEMs, and a display.  The video camera videos a monitored object as a motion picture sensed by the sensor.  Then the first MODEM compresses data representing the motion picture and transmits the data via the public line, such as a telephone line or an integrated services digital network line, to the second MODEM. The second MODEM restores the data compressed by the first MODEM into the original data, and outputs the original data to the display.  Lastly, the display displays the motion picture of the monitored object based on the original data transmitted from the second MODEM.  Since the monitoring system according to the present invention uses a public line, the cost of the monitoring system is less expensive than those which use a leased line.  The MODEM may be based on the V.42 specified by Comité Consultatif International Télégraphique et Téléphonique (CCITT).

A ball valve is disposed in the path of the flow channel to regulate the sauce flow. The socket has a built-in tamper-proof seal provided which is broken by a pulling ring. The outer periphery of the upper end of the socket is provided with male threads, so that a female-threaded cap can be placed thereon for the closure of the bottle, after the seal is broken and/or when the sauce is not in use. Cord means are provided for connecting the brush head assembly onto the neck of the sauce bottle for carrying along when the brush assembly is detached from the bottle and the bottle is capped.
