Title: Method for forming a composite resin seal
IPC: F16J15/32
Filed: 1984-11-27
Granted: 1990-04-24
Abstract: ABSTRACT     A method for forming a fluid seal for a liquid and gas-filled damper mechanism.  The seal includes a casing unit and a primary sealing ring subdivided into two portions, one portion being adapted to provide a fluid seal with an associated reciprocable rod, and the other to provide a one-way relief valve action to bleed fluid from one side of the lip body to the other when higher pressure is on the rod side; and to increase the sealing force when the higher pressure is on the other side of the sealing ring opposite the rod.  The method includes cutting the sealing ring in frusto-conical form from a resinous material, and supporting the ring while bonding this to the casing unit by molding an elastomeric collar which unites both of the parts.

Title: Self-contained rv sanitary systems
Inventor: SARGENT CHARLES L
IPC: B65D25/02
Filed: 1987-03-23
Granted: 1991-10-22
Abstract: ABSTRACT OF THE DISCLOSURE          A self-contained sanitary fixture, particularly for a recreational vehicle, comprises a bench supported on a base co-operatively defining a stowage compartment.  The bench contains a bowl having an outlet which connects to a tank in the stowage compartment.  A valve on the tank controls passage between the bowl and the tank.  The valve is itself operated from a knob on the bench through a coupling mechanism.  Waste water from the bowl is collected in the tank and is disposed of by sliding the tank out of the stowage compartment through an opening in the RV's sidewall and carrying the tank to a suitable disposal site.  The tank incorporates a rotatable pourspout and vent valve to facili-tate pouring waste contents out of the tank.  The connections between the bowl outlet and the tank and between the knob and valve automatically disconnect upon removal of the tank from the stowage compartment.  Similarly they automatically reconnect when the tank is inserted back into the stowage compartment.  There are numerous features to the invention including those in the fixture and its various parts and in relationships to the installation in the recreational vehicle.

Title: Translinear static memory cell with bipolar and mos devices
Inventor: HEALD RAYMOND A
IPC: G11C11/41
Filed: 1987-04-16
Granted: 1991-03-05
Abstract: ABSTRACT OF THE DISCLOSURE A translinear static memory cell employs both bipolar and metal-oxide-semiconductor technologies.  Bipolar transistors are employed as switching devices, whereas MOS transistors provide power supply and coupling functions.  Among other advantages, the bipolar transistors provide large changes in output current for small changes in input voltage, thereby enabling high level read signals to be obtained.
