Title: "s-a-v-e" (the short-aspirated-vortex-engine)
Inventor: SHORT FREDERICK J H
IPC: F02G1/00
Filed: 1991-08-16
Abstract: ABSTRACT             On the subject of 'Heat Engines' it has long been accepted that the 4stroke "OTTO" cycle heat engine is very much less efficient than the "Carnot" maximum efficiency percentage equation for heat engines allows.           I have built a "CARNOTTO" apparatus so named because it projects both Sadi Carnot's and Dr. Otto's ideas Using this apparatus to design a real working engine using conventional components found in our common current Heat Engines which invention I now refer to as "S-A-V-E " defined using my surname as the "SHORT-ASPIRATED-VORTEX-ENGINE".           I am submitting a basic three cylinder version though any combination of sets of three cylinders are optional Basically my invention allows compounding of the heat energy, redirecting such heat energy through additional useful working paths to create increased overall efficiency with less emissions.           The major extra heat energy path comprises a cylinder positioned between a left and a right 'PILOT" cylinder that alternatively discharge surplus heat energy onto the centre cylinder's piston 'crown' better described as a "SLAVE" in as much it obediently moves as the "MASTER" 'PILOT'cylinders input dictates.         Now in addition to my claims for greater overall efficiency, this "SLAVE" cylinder invites further improvements,namely injection of powdered solids, liquids or gases not solely to produce additional power but also to chemically change the products of combustion into environmental friendly emissions.
Patent CA-2051565-A1 (CA)
Inventor: BALLANTYNE RONALD
IPC: B30B15/24
Filed: 1991-09-17
Abstract: ABSTRACT OF THE DISCLOSURE   Press platens are maintained parallel in critical central regions proximate to a mold between the platens. Leveling cylinders acting between the platens to resist downward action of a central ram on a movable platen. Data identifying expected local platen deflection in response to various operating pressures of the leveling cylinders are recorded. For each leveling cylinder, the current operating pressure is determined and the relative spacing of the platens proximate to the leveling cylinder is sensed. The operating pressures of the cylinders are controlled in response to the sensed relative spacing of the platens and in response to the expected local platen deflection for each leveling cylinder at its current operating pressure to maintain a substantially parallel relationship between the platens proximate to the mold. The platen deflection data required for each leveling cylinder are obtained in a preliminary process involving operation of the platens to compress the mold, operating the leveling cylinders at their various operating pressures, and sensing and recording local platen deflection that results.

Title: Apparatus for making a torsion spring
Inventor: KETELAARS WILLIAM P
IPC: B21F35/00
Filed: 1991-09-26
Abstract: ABSTRACT OF THE DISCLOSURE          An  apparatus  for  making  double  coil  torsion  springs such as  ones  found  in reclining office  chairs  to  return  the chair to the upright position.  The spring has two coils on the same axis connected by an arm.  The problem in manufacturing the spring is that to wind both coils around a mandrel at the same time, the spring must be held between the coils during winding, and  once  winding  is  complete,  the  coils are  trapped  on  the mandrel by whatever is holding the spring between the coils.  A conventional  solution  is  to wind  the  coils  separately,  slide them off the end of the mandrel, and bend to bring them together to  form  the  spring.   This  is  slower  than  winding  both simultaneously and difficulties occur matching the ends of the coils,   Thus,  the  invention provides  an  apparatus  that  winds both  coils  at  the  same  time  and  allows  for  release  of  the spring.   The apparatus comprises,  a catch plate for retention and  winding  of  a  U-shaped  wire  blank  around  mandrels  held relative  to  and  driving  the  catch  plate.   The  mandrels  are retractable  to  release  the  wound  double  torsion  coil  spring allowing removal of the spring from the apparatus.

Title: Battery construction and method of connecting terminals to electrodes
Inventor: MIX RENARD E
IPC: H01M50/553
Filed: 1992-06-22
Abstract: CONNECTING TERMINALS TO ELECTRODES     Abstract Of The Disclosure A bi-polar battery has terminals of an electrically conductive lead based or other low melt point metal with connector straps fused to the rows of lead based lugs of electrode plates, that extend from the interior of a heat sensitive battery case of plastics material through slotted pockets formed in the case walls that contain beds of glass beads which effectively isolate the electrode plates from the straps while providing support for the lugs.  The ends of the battery case have insulator and positioning sections into which premolded terminals are fitted so that they can be subsequently heated into a melt for amalgamation to the lugs without heat damage to the case and so that the terminals are precisely located on the ends of the battery case.  A lug-terminal amalgamation process is disclosed in which the glass beads are fed into a first slotted pocket in a one wall of the battery case through which the lugs of a first set of electrode plates extend so that a sealing and heat insulating bed is provided between the connector strap of the terminal and the body of the electrode plates within the case.  Flux is applied to the lugs and the strap in the fusing areas, and the strap is subsequently installed over the lugs which protects the lugs from heat damage.  An induction coil is then placed over the strap and energized for a given period of time so that the strap changes to a molten state and flows onto the bed and between the lugs to fuse therewith.  The coil is removed and the terminal and lugs are cooled so that the molten metal solidifies to complete the terminal connection.  The process is repeated for joining a second terminal to a second set of electrode plates of different polarity than the first set.
