Abstract: ABSTRACT OF DISCLOSURE           An  air  cushion  restraint  system  (ACRS)  providing enhancements in the strength of the attachment between an air bag and  associated support  structure and  further providing improvements in the fabrication and assembly of such systems.          ACRS systems in accordance with this invention incorporate an air bag with  a  retainer  ring member which  reinforces  the inflation  or mounting  opening which  is  provided  to enable inflation gases to be vented into the bag and to mount the bag to the associated vehicle structure.  The retainer ring is sewn directly to  the  air  bag  at  the  inflation  opening  and  is preferably made  of  a  polymeric  material.   In  a  preferred embodiment the retainer ring features projecting post members which  enter  and  engage  with  apertures  in  a  corresponding mounting structure to prevent the air bag from pulling away from the attachment structures during deployment.

Title: Heating element and a method for manufacturing the same
Inventor: YAMASHITA KAZUO
IPC: H05B3/30
Filed: 1991-09-12
Abstract: ABSTRACT OF THE DISCLOSURE         A heating element for a cooking apparatus or a heating apparatus is manufactured by forming alumini-um layers on a nickel or nickel-base alloy base or forming nickel layers and then aluminium layers on a metal base, and by oxidizing the aluminium layers into an aluminium oxide layers.  At the oxidizing step, nickel-aluminium alloy layers with high corrosion resistance are also produced.  Only aluminium layers, not nickel layers, may be formed on a metal base and oxidized into aluminium oxide layers to obtain a heat-ing element with relatively low but practical corrosion resistance.  The resultant heating element by any of the above processes which does not require a cover or other protection against corrosion is formed into a sheet and heated to provide radiation of about 800°C.

Abstract: ABSTRACT OF THE DISCLOSURE      THICKNESS MEASUREMENT ON PRINTED PRODUCTS IN A SCALE FLOW     In a scale flow, particularly in A dense scale flow (54) of flat articles, e.g. printed products, the thickness of each individual element between a deflectable measurement part and a reference part is measured, in that the reference part in a timed movement for each measurement engages below that part of the scale which forms the surface of the scale flow.  In the preferred embodiment of the apparatus the reference part is constructed as an impeller (22), which is positioned laterally of the scale flow (54) in such a way that its vanes (22.1/2/3/4), if the impeller (22) is rotated about its spindle (23), are moved between the scale located on the surface and the remainder of the scale flow.  The deflectable measurement part is constructed as a sensing roll (21), which is pressed into an adjustable neutral position by a spring tension.  The deflection of the sensing roll (21) is measured and interrogated in timed manner.  The timed cycle of the movement of the reference part and the timed cycle of the interrogation of the measured value are synchronized and are matched to the speed of the scale flow and the reciprocal spacing of the scale flow elements.

Abstract: A system for preventing abnormal heating of a thermal head, which is configured with pure hardware.  In the system, when a temperature of the thermal head becomes an abnormally high temperature exceeding a predetermined temperature and/or an active time of a print-time setting signal cyclically issued from a microcomputer for activating the thermal head only for a time period necessary for printing of one line of picture image becomes abnormally long, a flip-flop is set so that three sorts of switch circuits are respectively operated in such a manner as follows, whereby the abnormal heating of the thermal head can be prevented at a very high reliability.    (1) The supply of a drive voltage to the thermal head for heating the thermal head is forcibly stopped.    (2) The input of the print-time setting signal to the thermal head is forcibly stopped.    (3) A picture image signal supplied from the microcomputer to the thermal head is cut off and, instead of the picture image signal from the microcomputer, a signal indicative of a non-printing picture image, e.g., all-white picture image, is forcibly supplied to the thermal head as the picture image signal.

Title: Spherical rotary pump
Inventor: ROSEBOROUGH TREVOR
IPC: F04C3/08
Filed: 1992-05-26
Abstract: ABSTRACT                  SPHERICAL ROTARY PUMP            In rotary pumps with positive displacement it is common to use moving vanes within the pump to create a seal to move the working fluid.  These vanes rub against the internal surfaces causing friction and the need for lubrication, which in turn limits the working temperature or requires cooling.   This invention uses two rotors within a spherical housing to move a working fluid with near positive displacement.  The rotors can rub against each other and the pump housing or can be supported by their bearings and turn on their shafts without actual contact and hence no friction or required lubrication.          Leakage around the sealing edges is offset by a very high shaft speed due to a rotary and frictionless pump.  Using a pump as compressor and another as a motor an engine similar to a turbine engine can be built but of a smaller size due to the near-positive displacement of the pump.
Patent CA-2069763-A1 (CA)
IPC: F16K3/02
Filed: 1991-05-31
Abstract: A gate plate assembly (20) has two aligned and connected body housing members (26) which each have a gate slot above a through passage which is above a seat portion slot. Gaskets (30) are compressed by the body housing members (26) to form a liquid-tight seal along the valve sides. Two resilient valve liners (24) are fitted between and compressed by the body housing members (26). Each valve liner (24) has a body with a planar front face (40) and a cylindricalthrough passage (44) which extends through the liner body. A seat portion (64) extends downwardly from the body of each liner (24) and increases in thickness as it extends from the body. The valve liners (24) are compressed within the body housing members (26) such that the planar front faces (46) are adjacent one another and the seat portions (64) are compressed within the seat portion slots (80) to produce a tight seal along the bottom of the valve assembly (20). A packing filled chamber (100) at the top of the assembly forms a tight seal at the top of the valve. An imperforate gate (22) is slidable through the gate slots toalternatively obstruct and permit fluid flow through the valve (20). The seat portions (64) extend to the bottom of the valve such that particles trapped between the seat portions (64) may be expelled form the valve between the seat portions (64).
