Abstract: This invention relates to a novel pressure sensitive adhesive formed of a liquid and solid rubber which is substantially resin free. Preferably the adhesive is formed of a weight ratio of solid rubber to liquid rubber of about 1:0.5 to about 1:7. These adhesives exhibit improved adhesion in cold weather and oily surface applications and other properties. The pressure sensitive adhesives can be used in health care, industrial and drug delivery systems.

Abstract: A tap to a process fluid line includes a pressure sensitive cap. The force necessary to remove the cap on the tap is directly proportional to the pressure buildup inside the cap so that an operator can take safety measures before removing the cap. The tap includes a base having a first set of reusable threads thereon and a cap having a second set of reusable threads therein which engage with the first set of threads on the base. A hollow fill tube communicates fluid from the process fluid line through a ball valve to a sample bottle when the cap is removed. The resistance provided by the reusable threads is linear and consistent throughout the entire threading and unthreading procedure. In this manner the force necessary to remove the cap is proportional to the pressure buildup inside of the cap. A helical spring is attachable by an anchor to the fill tube and can be employed to steady the mouth of the sample bottle as it is filled by the fill tube.

Abstract: The present invention relates to a burred fastener for forming a friction fit between the fastener and a driver. The friction fit retains the fastener in contact with the driver during insertion, tightening and loosening of the fastener into a work surface. Burrs are formed in the inner side surfaces of an indentation or slot formed in the fastener head. A method for forming the burred fasteners includes striking the screw head with a deformation object.

Abstract: An improved polyurethane is prepared by reacting a diol component and an organic diisocyanate with critical selection of the amount of water in the reaction mixture and the diol component. The diol component is a long chain polyoxyethylene glycol optionally mixed with a low molecular weight polyoxyethylene glycol. A tough gel can be formed by mixing the polyurethane in a diol or triol and water solution. The tough gel can be used in burn and wound dressings, electroconductive pads, high slip materials and surgical implants. An optically clear gel can also be formed. Solutions and emulsions can be formed of the polymer and can be combined with fillers to form face creams and antiperspirants. A film can cover one side of the gel for burn and wound applications. The gel can be used in squeeze tubes and in spray cans in burn wound care dressings and industrial applications and in bags and containers for use in plastic surgery implants.

Abstract: The present invention relates to a method and apparatus for forming a drinking vessel which is substantially free of contaminants. A consumable liquid is added to a container. The liquid is stirred while freezing the liquid allowing contaminants to flow towards the center of the liquid. A layer of ice forms on the inside of the container which is substantially free of contaminants to form the drinking vessel. In one embodiment, gas is bubbled into the liquid for stirring the liquid. Alternatively, a propeller can be used to agitate the liquid.

Abstract: This invention relates to a novel method and system for recovering water from fruit. Water is evaporated from juice during a concentration process. The water can be bottled and distributed to consumers. Water vapor is condensed and water is collected. Preferably, a distribution cone is used for evaporating the water vapor. The water produced has improved purity characteristics.

Abstract: The invention relates to vanadium/phosphorus oxide catalyst precursors useful in preparing catalysts useful in the oxidation of hydrocarbons containing 4 carbon atoms to maleic anhydride.

Abstract: The present invention is a device which can be portable and easily attachable and removable from existing dental work station tables. The apparatus comprises a work platform which can be removably connected to the work station table. A suction tube at the work station can communicate with the surface of the work platform. The suction tube can easily be connected and disconnected from the work platform for use in treating the patient, such as providing mouth suction. The apparatus preferably is supported by a mounting means on the work table with the work platform preferably horizontal. Preferably the platform is supported by a support means through which it is attached by the mounting means to the table. The work platform thereby provides both support for the article being worked on and suction to remove debris.

Abstract: Gel film-forming flexible collodion compositions can be improved by including one or more topically acceptable polymers in an amount sufficient to increase the resilience of the film formed. Suitable polymers include polyalkylenes and (meth)acrylate homo- or copolymers. The compositions can further include salicylic acid and a topically acceptable crystallization inhibitor in an amount sufficient to suppress the crystallization of dissolved salicylic acid from the composition.

Abstract: The present invention relates to a speaker recognition method and system which applies adaptive component weighting to each frame of speech for attenuating non-vocal tract components and normalizing speech components. A linear predictive all pole model is used to select frames for an adaptively weighted cepstrum. Frames with a predetermined number of resonances are selected for cepstrum analysis. An adaptively weighted cepstrum is determined from a new transfer function. A normalized cepstrum is determined having improved characteristics for speech components. From the improved speech components, improved speaker recognition over a channel is obtained.

Abstract: A water quick disconnect assembly for improving removal of cages from an outside water supply. The assembly automatically turns off a water supply and disconnects a cage from a cage rack system. A water line connector attaches to an outside water supply. A water valve positioned within a cage barrier is locked to the water line connector when water is supplied to the cage. A linking member pivotally attaches to the water line for closing the water line. A knob assembly attaches the linking member to a pull cable. When the pull cable is pulled away from the cage, the water line connector is pivoted in a clockwise direction for disconnecting the water supply to the cage. The knob assembly provides positive visual indication of whether the cage is connected to the water supply or disengaged from the water supply. The quick disconnect system is a positive unlocking system.

Abstract: The torsion beam for a suspension is formed of a hollow shaft having a cross section substantially of the shape of an inverted letter U. It, therefore, can be manufactured simply and is enabled to enjoy light weight and improved torsional rigidity. This torsional rigidity can be adjusted and the amount of offset of the joined parts of opposite wheel supporting members from the other component parts can be freely adjusted. The end plates are constructed of a plurality of mutually joined end plates and the torsion beam is joined by welding to the surface for mounting the beam after the end plates have been machined. Thus, the torsion beam type suspension is manufactured with a relatively simple equipment, with the result that cost of equipment and the cost of production are lowered.
