Title: Vented valve for internal combustion engines
Inventor: HUFF REGGIE D
IPC: F01L3/00
Filed: 1990-02-09
Abstract: ABSTRACT:          A two part intake or exhaust valve comprising an inner and an outer valve, both circular in shape, with the inner valve having a longer stem of a smaller radius to extend above the outer valve. The outer valve has a hollow stem large enough to accept the inner valve, also a valve seat in the center of its bottom face to seat the inner valve, and the top side of its base is equipped with vents. Both valves have separate springs of appro-priate size affixed under valve spring retainers and retainers locked in place with retainer locks. The inner valve is equipped with a groove under the retainer to accept a heavy clip or stop disc. The purpose of this valve mechanism is to create a two stage event when atmosphere enters or exits a combustion chamber.          This will allow more atmosphere to enter or exit the combustion chamber than is possible with a single valve arrangement. In addition, this will cause two different speeds of atmospheric movement, creating low pressure in the center, via the inner valve, creating a vortexial storm or swirl effect. The result is more power and better fuel efficiency than can be realized with state of the art valve arrangements.

Title: Demand valve for a respirator
Inventor: LEWIS ROBERT D
IPC: B63C11/22
Filed: 1990-05-15
Abstract: AN IMPROVED DEMAND VALVE FOR A RESPIRATOR              Abstract of the Disclosure A demand valve for a respirator.   A fixed tube directs pressurized air flow from the source into an opening for a mask.   The venturi  effect  caused by directed air flow through the housing acts to draw the diaphragm toward the respirator face mask.  A portion of  the  air  directed  by  the  tube  escapes  and  is directed over the tube by a hinged three sided arm.          Air flow so directed by the arm creates a low pressure area within the arm thus pulling the arm toward the tube.   The arm is in engagement with the stem of an air valve which when the arm is drawn toward the tube opens the valve to provide continued air flow into the mask without continued effort on the user's behalf.

IPC: A61M5/32
Filed: 1990-09-17
Abstract: (57) Abstract A safety syringe for preventing "needle stick" injury and/or reuse of the syringe. The syringe comprises a body (2), a plunger (4) mounted within the body, connection means (24) for connecting the plunger (4) to a needle holder (6) carrying a needle at the end of an in-jection stroke of the plunger (4) whereby subse-quent retraction of the plunger (4) withdraws the needle holder (6) and the needle into a shielded position within the body (2). The with-drawal of the plunger (4) is effected by a vacu-um chamber (18) defined between the plunger (4) and the syringe body (2), vacuum being created within the chamber (18) by movement of the plunger (9) during the injection stroke and serving to withdraw the plunger (4), the needle holder (6) and needle after injection pressure is removed. The syringe may be pro-vided with braking means (20) to control the rate of withdrawal or the needle and/or to pre-vent withdrawal until the injection stroke of the plunger (4) has been completed.

Inventor: CIDECIYAN ROY D
IPC: G11B20/14
Filed: 1991-07-12
Abstract: For encoding a stream of k-bit data bytes into a stream of m-bit code bytes satisfying given constraints, a coding principle and coder apparatus are disclosed which allow pipelined and parallel handling of the byte stream. Each data byte DB and an associated coder state indicator S are together converted into a code byte CB. The coder state indicator S(i) to be associated with a databyte DB(i) is obtained by logically combining the coder state indicator S(i-1) of the preceding data byte DB(i-1) and a state transition indicator T(i-1) derived from the latter. This allows the simultaneous generation of all coder state indicators S for a whole group (a word) of data bytes thereby enabling the parallel and pipelined operation of the coder.
