Title: Water and additives conservation system for water closets.
Inventor: ASFAR JAMAL J
IPC: E03D1/14
Filed: 1991-07-15
Abstract: ABSTRACT OF THE DISCLOSURE            The present invention WATER AND ADDITIVES CONSERVATION          SYSTEM FOR WATER CLOSETS relates to a water closet flushing system to reduce water usage in domestic and public toilets and to improve the utilization of additives.   The flushing system  can  utilize  the concepts of either a multiple compartment tank or the use of a tank with discharge points and/or valves positioned at different elevations within the tank.          Corresponding to the different volume usage required are actuators which can be levers, push buttons, push buttons with timers,  or some other electronically activated selection board.  Based on the quantity of water to be used for effective flushing designated actuators can be utilized.  For example, to utilize minimal volume for flushing to ensure an effective urine disposal a certain actuator is manipulated.  To energize a regular volume flush for solids disposal, another actuator may be depressed.          In cases where additives to the bowl such as cleansing solutions, disinfectants or deodorizers are utilized a small chamber within the tank is provided.   To introduce these solutions a separate release valve into the bowl can be used.  Also, the admitting valve from the additives chamber into the bowl can be activated with a time delay mechanism. After the flushing action is completed, the dispensed material stays within the toilet bowl and thus is not wasted by being flushed down into the sewer.

Title: Process for Inflating a Gas Cushion and Safety System of the Air Bag Type
Inventor: KETTERER DIETER
IPC: B60R21/26
Filed: 1991-01-29
Abstract: The motor vehicle is provided with an air-bag (110) to protect the occupants in the event of a crash. The air-bag is folded to a compact shape and fitted in a recess in the hub of the steering wheel. The folded air-bag surrounds a vessel (2) which contains the gas, or means to produce a gas, with which the air-bag is inflated. The gas or means to produce the gas are so chosen that the air-bag is inflated to the required size and pressure irrespective of the ambient temperature. This may be achieved by adding chemicals to the gas in order to heat it if necessary.

Filed: 1991-09-20
Abstract: An automatic gain control apparatus and method which optimally adjusts the gain of an amplifier (105) to compensate for time-varying energy levels of a received input signal (I/Q). A control input signal VCTL for adjusting the gain of the amplifier (105) is determined by the selective average energy level (305) of a present input signal (309), the transfer function characteristic of the amplifier (105) and a previous control signal. A fast loop response time maintains the energy level of the amplified output signal at a nominal level.

Inventor: DAWS GREGORY R
IPC: A01C7/08
Filed: 1991-09-26
Abstract: TITLE Apparatus and Methods For Selectively Creating Tramlines The selective creation of tramlines is disclosed where the metered seed normally delivered through the outlet hose (18b) of the row planter unit (20b) corresponding to the desired location of the tramline is diverted by a butterfly valve (26) to one or both of the row planter units (20a, 20c) located adjacent to and on opposite sides of the row planter unit (20b). The butterfly valve (26) includes an inlet conduit (28) which intersects with first and second outlet conduits (30, 32) and a butterfly element (34) which is pivoted by a solenoid actuator (40) against the bias of a spring (36) to selectively block one of the outlet conduits (30, 32). In the preferred form, the diverting hose (44, 54, 56) from the butterfly valve (26) may extend through the housings (24) and be in direct communication with adjacent row planter units (20a, 20c) or may be connected to Y-shaped connectors (46) having a passage (50) intersecting with the passage (48) that the metered seed for the adjacent row planter units (20a, 20c) would normally pass for mixing the metered seed. A divider (52) may be provided for dividing the metered seed diverted by the butterfly valve (26) between the two adjacent row planter units (20a, 20c). A preferred form of the butterfly valve (26) is also disclosed including first and second shoulders (90) formed in the walls (64) of the housing (58) adjacent to the inlet passageway for nesting of the free edge of the butterfly element (34). Additionally, the head portion (80) of the butterfly element (34) includes a semicylindrical portion (86) pivotal within a semicylindrical depression (72) formed in the V-shaped outlet wall (68) of the housing (58) and includes a V-shaped portion (88) extending from the semicylindrical portion (85) to the flat surfaces (84) of the dividing portion (82) of the butterfly element (34).

Filed: 1991-11-08
Abstract: A component with an unlock mechanism is unlock-ably locked with respect to another component by a re-silient snap tooth engaging in a hole defined in the other component.  To unlock the components from each other, the unlock mechanism is pulled between the components to force the snap tooth out of the hole against its resiliency.  The unlock mechanism has a slant surface that slides against a slant surface of the snap tooth to displace the snap tooth out of the hole in response to the movement of the unlock mechanism.

Title: Method for forming disposable garments with a waste containment pocket
Inventor: CUCUZZA CARL C
IPC: A61F13/15
Filed: 1991-12-04
Abstract: METHOD FOR FORMING DISPOSABLE GARMENTS WITH A WASTE CONTAINMENT POCKET            Abstract of the Disclosure A method is disclosed for forming a dispos-able garment with a waste containment pocket defined by a pair of barrier cuffs located on opposed sides of the centerline of the body contacting layer of the garment inboard of its elasticized leg openings.  Each barrier  cuff  is  formed  by  applying  a  pattern  of adhesive alongside of an elastic member maintained in tension on the body contacting layer or a separate strip of material, and then intermittently applying an adhesive pattern onto the elastic member so that it bonds to the body contacting layer or separate strip at longitudinally spaced locations therealong.  When the tension on the elastic member is released, gathers or folds are formed in the barrier cuff between those locations where the elastic member was adhered thereto which help the garment conform to the shape of the wearer and prevent the passage of body exudates to the elasticized leg openings.

Thereafter,  a rigid and relatively flat backing strip is provided and the extruded length is deflected to bring the back side of the tapered thickness end portion of the length into engagement with the backing strip.  The back side of the extruded length including the tapered thickness end portion is then bonded to the backing strip which maintains the strip in a relatively flat condition.
