Title: Self-contained swab unit
Inventor: SNYDER THOMAS A
IPC: A61J1/06
Filed: 1981-03-06
Granted: 1984-01-24
Abstract: SELF-CONTAINED SWAB UNIT     ABSTRACT OF THE DISCLOSURE     A self-contained swab unit comprises a cylindrical plastic tube having a foam rubber swab capping one end. The tube is closed at the opposite end by a heating and crimping process.  A cleansing or sterilizing solution is loaded into the tube.  The tube is sealed by a generally conical plug having a base slightly lar-ger than the inside diameter of the cyl-inder, so that the solution is sealed away from the foam rubber swab when not in use.  Squeezing the tube causes the plug to pivot in relation to the side-walls of the tube so that the seal is broken and liquid may saturate the swab.  Releasing the squeeze pressure on the tube causes the plugs to pivot back into a partial seal so that the amount of fluid used in swabbing can be controlled.     ?381-5

Abstract: ABSTRACT OF THE DISCLOSURE:        This invention is directed to a method, a rubber skim stock and a product containing the skim stock having improved adhesion between a-metal member and contiguous rubber skim stock. The invention lies in the discovery that improved rubber-to-metal adhesion can be obtained by adding to an otherwise conventional rubber skim stock composition appropriate amounts of a tetracarboxylic dianhydride. The method of this invention comprises the steps of mixing a tetracarboxylic dianhydride into a rubber composition, bringing this composition into contiguous relationship with a metal member in an unvulcanized product and vulca-nizing the product to yield the end product.

Abstract: TWO STAGE CONTROL CIRCUIT FOR REVERSIBLE AIR CYCLE HEAT PUMP                     ABSTRACT OF THE DISCLOSURE          A two-stage circuit for controlling all operational functions of a reversible air cycle heat pump unit, including room thermostat functions and defrosting functions.  All user controllable functions are controlled via a remotely locatable thermostat-like control unit mounted on an inside wall of the room separate from the heat pump unit, and connected to the heat pump unit with only five conductors.  A number of desirable functions and features are provided.  For example, for optimum energy usage the control provides two stages in both beating and cooling modes of operation, with almost constant temperature differential between the two stages regardless of temperature setting, and almost constant hysteresis for each stage.  To facilitate compliance with Government-imposed regulations where applicable, heating and cooling limits are independently adjustable without any modification whatsoever for use in those public buildings where heating and cooling must be limited.

Abstract: CARBON-CAFFEINE SEPARATION ABSTRACT The object of the invention is to provide an improved process for recovering caffeine adsorbed on activated carbon. Caffeine removed from the commercial decaffeination of vegetable materials and extracts can be effectively removed from the extraction solvent, or can be purified, by the use of activated carbon. Unfortunately, the caffeine is tenaciously held by the carbon and none of the techniques currently available for removing the caffeine is wholly satisfactory. The recovery of caffeine from activated carbon is accomplished according to the present invention by employing a liquid food-grade caffeine solvent which comprises an organic acid or alcohol, and which is capable of competing for the active sites on the carbon occupied by the caffeine to displace at least a portion of the caffeine which is then dissolved in the solvent. After the desired period of contact, the caffeine is separated from the solvent. The solvent will preferably comprise glacial acetic acid or an acetic acid azeotrope, and contact will preferably be at a temperature above 100 C.

Abstract: STEAM TURBINE CONTROL APPARATUS     Abstract of the Disclosure Control apparatus is disclosed for limiting overspeed in a steam turbine following a sudden loss in load.  The apparatus includes at least one valve disposed in the steam conduit interconnecting higher and lower pressure sections of the turbine and an actuator for controlling operation of the valve between a fully open position and a pressure-relief position wherein the valve functions as a pressure relief valve.  During normal operation, the valve is maintained in the fully open position.  On receipt of a turbine overspeed signal, the valve is actuated to the pressure relief position and a volume of steam at a preselected pressure,  necessary to open the valve, is held back within the turbine stages, crossovers, and so forth.  This retained steam is thus prevented from adding energy to increase the speed of the turbine rotor.  During turbine startup, the valve is operated in its pressure relief position to permit preheating of the higher pressure sections of the turbine, avoiding long and costly startup procedures.
