Patent CA-1299539-C (CA)
Title: Universal cup holder
Inventor: WRIGHT WILLIAM T
IPC: B60N3/10
Filed: 1986-07-29
Granted: 1992-04-28
Abstract: Abstract of the Disclosure A universal holder of the top loading type for accommodating and safely supporting a drink container of any of a wide variety of sizes and configurations, comprising a vertical backbone member that supports a pair of highly flexible, symmetrically configured arms each possessing substantial curvature. The two arms together form a generally circular configuration, with the tips of the arms being in general alignment, but not coming into contact with each other during normal use of the holder.  The arms preferably are of non-constant cross section, possessing substantially smaller vertical dimension at their tips than adjacent the location of their attachment to the vertical backbone member.  Importantly, the uppermost surfaces of the arms are flared somewhat outwardly to facilitate the downward insertion of a drink container therebetween, with the arms being sufficiently flexible as to accommodate drink containers of many different diameters, and up to a maximum diameter of at least four inches.  The arms clasp the drink container sufficiently tightly in each instance as to prevent dislodgment of the drink container from the holder, but not so tightly as to crush a drink container made from paper or foam plastic.  The variation of vertical dimension of the arms from their attachment point to their tips may be in a ratio of approximately 3.125 to 1, and two external surfaces of the holder are substantially flat to accept one or more strips of VelcroTM to be utilized for mounting the holder to either a substantially horizontal, or to a substantially vertical surface.  Quite obviously, our invention is not to be construed as being limited to holding drink container

Title: D.c. power control for d.c. solenoid actuators
Inventor: D ONOFRIO ANTHONY
IPC: H01H47/32

Granted: 1991-05-07
Abstract: Patent Case No. m30-04331-U.S.        APPLICATION OF                     ANTHONY D'ONOFRIO                   D.C. POWER CONTROL FOR                   D.C. SOLENOID ACTUATORS         ABSTRACT   A D.C. power control for a D.C. solenoid actuator which may be used for a D.C. solenoid operated valve uses a timer circuit for switching from an initial high pull-in power after a predetermined delay to a low hold power for the valve solenoid utilizing a pulse control where the valve "on" time is held constant and the "off" time is varied.          The pulses are  high frequency to prevent the valve from switching with each of the pulses while enabling the average current in the valve solenoid coil to be controlled independently between the pull-in and hold current values.

Patent CA-1287346-C (CA)
Title: Joint sleeve for pipe
Inventor: DANA WILLIAM R
IPC: F16L21/02
Filed: 1987-08-21
Granted: 1991-08-06
Abstract: JOINT SLEEVE FOR PIPE         Abstract of the Disclosure A joint sleeve is set forth for sealing the ends of adjacent pipe sections.  Each pipe section end has a compressible sealing gasket encircling it proximate its end and a shoulder remote its end.  The joint sleeve consists of a body able to encircle the pipe section ends and to compress the sealing gaskets so that an adequate seal is provided when the sleeve is disposed about adjacent pipe section ends.  To resist the force imposed upon the sleeve by the rolled gasket which tends to urge the sleeve from the pipe end, the joint sleeve has an inner surface with a flared portion.  When the sleeve is positioned on one pipe section end for storage and transport, the compressed gasket by virtue of the flared portion produces an axial force urging the joint sleeve body in a direction opposite the force imposed by the rolled gasket and against the shoulder to hold the sleeve on the one pipe section end.         To assemble the pipe sections, the end of the other pipe section is inserted into the sleeve which also results in a force urging the sleeve against the shoulder.  Due to the weight of the pipe sections, the reaction forces from the gaskets are ineffective to displace the pipe sections.

Title: Dispenser pump
Inventor: WASS ANTHONY
IPC: B65D47/34
Filed: 1987-12-15
Granted: 1993-07-06
Abstract: ABSTRACT     LIQUID DOSING DEVICE     A dispenser pump comprises a pump chamber having a flexible wall for altering the volume of the chamber.  The flexible wall is a polygonal pyramid, preferably five-sided, with facets interrupted by respective cylindrical surface portions inclined to the facet so as to induce bending thereof when the wall is flexed on actuation of the pump, thereby producing a force tending to restore the flexible wall to its rest condition.  An inoperative condition of the pump may be achieved by relative rotation of two body parts of the pump about the axis of a slidable telescopic guide connection between the flexible wall and a relatively fixed body part, a discharge nozzle of the pump being out of register with an outlet port of the pump in the inoperative condition.  The flexible wall, an essentially rigid boundary portion thereof, an essentially rigid guide member that moves with it and the discharge nozzle may be formed together as a one-piece integral part of e.g. polypropylene.

Title: Suction accumulator having slide valve
Inventor: GANNAWAY EDWIN L
IPC: F25B43/00
Filed: 1988-05-03
Granted: 1992-03-17
Abstract: ABSTRACT    A suction accumulator for the compressor of a refrigeration system is disclosed in which a suction tube (30) connected to the outlet of the accumulator extends vertically within the accumulator vessel (14) and has liquid metering openings (44) located adjacent to the bottom of the vessel and a gas inlet openings (40) located adjacent to the top of the vessel between the liquid metering openings and the accumu-lator outlet along the length of the suction tube.  A float valve member (46) surrounds the suction tube and is slidable along the vertical length thereof. In response to the accumulation of liquid refrigerant, the valve member (46) covers the gas inlet openings (40) to prevent introduction of liquid refrigerant therethrough.  Extension of the gas inlet opening along the vertical length of the suction tube provides progressive opening and closing by the valve member in response to changes in liquid accumulation.

Title: Optical displacement sensor
Inventor: CORPRON GARY P

Filed: 1988-05-13
Granted: 1991-11-26
Abstract: ABSTRACT OF THE DISCLOSURE       The    optical     displacement   sensor modulates intensity of the light   beam as a function of the physical displacement.   The sensor includes a reflector        positioned in a path of the light beam between a slight source          and a light detector .  The reflector         has a non-reflective portion         surrounded by a reflective portion .  Relative movement (displacement) of the beam and the reflector occurs as a function of a parameter which is being sensed.  In a normal (no displacement) condition, the non-reflective portion   can be positioned with respect to the light beam so that intensity of the light beam received by the detector is at a minimum, and the sensor         is operating in a darkfield mode.  Displacement from the normal position causes an increase in the light intensity received by the detector.

Abstract: CATALYTIC DEWAXING PROCESS USING BINDER-FREE CATALYST                                ABSTRACT          A catalytic dewaxing process in which a waxy hydrocarbon feed is dewaxed over  binder-free zeolite dewaxing catalyst.  The absence of binder reduces catalyst aging especially when operating at controlled space velocities in the range of 0.25 to 1.5 LHSV. The process is especially useful with lube oil stocks where aging problems are particularly severe, typically highly waxy stocks or stocks containing high levels of nitrogen.  Preferred catalysts are the intermediate pore size zeolites such as ZSM-5, ZSM-11 and ZSM-23.

Abstract: ABSTRACT     This invention relates to the automatic control of work platforms and in particular to a circuit means that provides a safe operation and automatic relevelling of a work platform that is being raised and lowered by electrically powered hoists.    Angle sense means are used to detect out of level orientations of the platform either along the longitudinal or transverse axis of the platform. When the angle sense means signals are interpreted by the circuit means appropriate hoist control signals stop the travel of the platform for a pre-determined period, control the hoists to bring the lowest portion of the platform up into a substantially level position, stop the travel of the platform for a pre-determined period and recommence the direction of travel of the platform.
