Abstract: ABSTRACT        A  bracket  assembly  for  supporting  a  cylindrical canister, such as a fire extinguisher, includes a base unit having a longitudinally extending, transversely concave, front surface  for cradling the canister therein and a separate flexible strap member which can be wrapped around the canister to hold it against the base unit.   The base unit includes opposing cutouts in the sides thereof into which a central section of the strap can be pressed before mounting on the wall so as to interlock the strap member with the base unit.  One end of the strap has a hook member thereon for engaging the other end of the strap by way of a selected one of a plurality of mating apertures therethrough.  The back surface of the base unit  is  transversely  concave  and  the  strap  member  has rearwardly projecting wedge members which engage the wall during mounting and preset the strap to conform generally to the shape of the back surface.   The bracket assembly is inexpensive to produce, provides support for a canister, is universal in nature in that it will accommodate different canister sizes and configurations, and it is capable of quick release if necessary.

Title: Power transfer circuit including a sympathetic resonator
Inventor: BOSSI BURT J
IPC: B42D15/10
Filed: 1989-02-28
Granted: 1994-03-15
Abstract: Abstract A power transfer circuit includes first and second windings sharing a common magnetic core. Each winding has associated with it a parallel capacitor to thus form a pair of "tank" circuits. The first winding is connected at one end to a voltage supply and, at the other end, to ground through an FET switch. The switch is turned on and off at a predetermined frequency and at a 50% duty cycle. The second winding and associated capacitor achieves parallel resonance at the predetermined frequency. Similarly the combined first and second windings and associated capacitors achieve parallel resonance at said predetermined frequency. The second winding need not be electrically connected to the first winding which transfers energy to it through the magnetic core. The transfer circuit efficiently couples power across a dielectric interface to a pickup coil. One particularly good application of the power transfer circuit is in connection with a contactless Smart Card.

Abstract: ABSTRACT     An improved planetary gear box for a heavy duty truck jack which includes a planetary gear box that provides high torque and in-line input and output shafts and a high gear ratio and a compact package which does not require many precision machine parts.  The invention uses parts formed by stamping rather than machining and uses a floating ring gear which can move relative to the housing, thus, allowing a stamped ring gear to be utilized.  Floating planetary gears are used by providing slotted carriers which allow the planet gears to float which eliminates concentric problems with the planet gears and the carrier assembly.  The invention allows the use of a stamped housing and the rear carrier of the planet gears is staked to the drive pilot of the jack screw.  The invention results in an improved and less expensive jack than utilized in the prior art.

Title: Peripheral device power activation circuit and method therefor

Granted: 1992-06-23
Abstract: ABSTRACT OF THE DISCLOSURE           A first embodiment of the present invention has toroidal current transformer having its outputs connected across full-wave bridge rectifier.  The induced, rectified current produced by full-wave rectifier is converted to a voltage by a load resistor.  This voltage is compared to a reference signal, the magnitude of which corresponds to a quiescent current level, by a comparator.  When the load resistor voltage exceeds that of the reference voltage, a current surge is detected.          The output of the comparator is directed to a retriggerable monostable multivibrator which produces an activation pulse of a selectable and known duration.  The activation pulse is directed to an electromagnetic or solid-state relay which activates peripheral device by connacting it to its power supply.  The second embodiment of the present invention has a line sensor electro-magnetically coupled to a power supply line.  The output of the sensor is integrated by an integrator.  The integrated signal is then digitized by a digitizer and input into a selector.  A crossover detector and a line voltage sensor are operably connected to a power supply line to monitor the crossover points and voltage level of the supply.  The monitored voltage is digitized by a digitizer and input into a selector.  The selector alternatively supplies a microcontroller with the digitized line current and voltage level values.  The microcontroller compares the relative values of the line current and voltage level to detect current surges in a power supply line due to increased activity of the parent device.  The microcontroller then activates  a solid-state relay, thereby activating a peripheral device.

Abstract: A tamperproof identification card such as a passport or credit card is provided. A diazo photosensitive composition is intimately mixed with a thermo-adhesive resin and is carefully deposited as a uniformly thin layer in one or more zones on a plastic support material. The zones of the photosensitive compositions are developed to reproduce identifying information such as a photograph, identification number, etc. A plastic protective film is then laminated to the support to protect the identifying information. Since the adhesive resin material is intimately mixed throughout the photosensitive composition, the protective plastic film cannot be removed without destroying the information.

Abstract: Particulate catalyst which has been used in a hydrocarbon conversion process such as catalytic reforming is regenerated in a moving bed regeneration zone (12). The catalyst being regenerated is passed into the top of the zone (12) and slowly moves downward as a dense bed (14, 19, 20) which is contacted successively with an oxygen-containing gas stream (31), a temperature-adjusting gas stream (30) and either a drying gas stream (37) or a chlorination gas stream (39) or both at different elevations within the regeneration zone (12). A key feature involves employing a portion of relatively hot combustion gas (26) withdrawn from one portion of the zone (12) as the temperature-adjusting gas stream (30) in a different portion of the zone after compression, with the remainder of the compressed combustion gas (27) being cooled (32) and recycled to the combustion zone as the gas stream (31). This eliminates the need to employ a heater to provide a suitable heating gas stream.

Abstract: A pressure diffuser (10) includes in a liquid-tight pressurized vessel (12) a vertical screen (24) which defines with a vessel wall (14) first and second interior volumes (26, 29) for transmitting pulp from a pulp inlet to a pulp outlet and receiving displacement (e.g. wash or bleach) liquid transmitted from headers (28) through the pulp. The screen ends around housing members (20, 22) have different cross-sectional areas, and quick movement of the screen effects backflushing. The volumes (26, 29) are segregated by the vertical, generally cylindrical, screen (24). A chamber (42) is provided in communication on opposite sides of a piston (44) therein with the pulp adjacent the pulp inlet (16), and the extracted liquid (in 29). By displacing the piston with a cylinder (50) immediately prior to rapidly moving the screen vertically with a hydraulic cylinder (50) to effect backflushing through the screen, the pulp pressure on the screen is reduced and at the same time shocks and compaction of the pulp adjacent the inlet caused by the movement of the screen are avoided.
