Abstract: A shut-off valve assembly for regulating the flow of fluid through or from a fluid line. The assembly comprises: a body attachable to or within a fluid line and having a chamber therein with inlets and an outlet for fluid from the fluid line; a valve seat that provides the outlet; a baffle arrangement including a baffle housing; a valve member having a sealing member movable between a shielded position, whereby the sealing member is substantially shielded by the baffle housing from a fluid stream moving from the inlets to outlet, and an unshielded position, whereby the sealing member can be forced by the fluid stream against the valve seat to seal the outlet; and a solenoid-spring drive for moving the sealing member between the shielded and unshielded positions.

Abstract: A rotary press is supported on a frame allowing liquid and solid receivers to be placed underneath the rotary press. The rotary press has an outer ring and an inner drum. The inner drum has an upper and lower flange with a stripper ring retained between these flanges. The flanges form two sides of the cavity where the pressing takes place. The flanges carry the solids away from the pressing zone to a discharge zone where the stripper ring expels the solids. By transporting the solids away from the pressing zone where liquids are expelled, reabsorption of the liquid is avoided. The stripper ring can move relative to the two flanges and is biased against the outer ring by the inner ring. The stripper ring applies pressure to the material to be processed and also pushes solid material from between the upper and lower flanges to fall into a receiver for the solids.

Abstract: A water treatment product comprising a mixture of at least one active ingredient and a first fluid, wherein the concentration in the product of the active ingredient is at least 50% on a weight basis and the viscosity of the product is at least 2,000 centipoise or 2 pascal seconds, the product adapted to be further diluted upon addition to a second fluid stream to be treated.

Abstract: A system and method for determining the absolute position of a linear or rotary actuator. A code plate having a series of digital words thereon is associated with the linear or rotary actuator. Each of the digital words consists of a plurality of bits, each bit consisting of a series of parallel encoder elements, each in the shape of a wedge. One or two optical sensor heads would be used in conjunction with a signal processor to determine the exact position of the code plate, and, in turn, the linear or rotary actuator. The exact position of each of the sensor heads with respect to the code plate is determined based upon the value of optical signals reflected off of the wedge-shaped elements and detected by each of the optical sensors.

Abstract: A medical valve includes a valve body having a central fluid passageway defined therein. A movable piston adapted in size and shape to be located within said central fluid passageway of said valve body. A sealing interface is defined between said movable piston and said central fluid passageway. An upper seal is located at an upper portion of said sealing interface. It is formed by a seal carried by said valve body. A lower seal is located at a lower portion of said sealing interface, and is formed by a seal carried by said movable piston. The lower seal remains intact until after said upper seal is broken.

Abstract: A jerky dehydrator comprises several baskets for receiving and retaining the product to be dehydrated and a racking grid for retaining several baskets in a vertical orientation. The racking grid is inserted into a metal tray, and the tray is inserted into the oven of a household range. The oven is preheated, prior to inserting the tray and its contents. Subsequently, the oven is maintained at a low temperature, about 200°, and the door of the oven is held open, slightly, to allow moisture to escape. Each basket comprises a first grate and a second grate, retained in pivotal relation by a pair of hinge clips. Tension springs, secured to an anchor on one grate and an extension on the other grate, urge the grates togther to form a basket and retain the jerky therebetween during the dehydration process. Receptacles at the trailing edge of one grate slip over upstanding pins on the racking grid and lock each basket in its vertical orientation.

Abstract: A testing harness for a design-under-test is modified to include a standalone implementation of an application programming interface used in developing the design-under-test. The standalone implementation is adapted to a target device, and is packaged with an executable application or MIDlet, together with any needed resource files. Either the package, or optionally a JAR and JAD file, is downloaded to a remote user for execution on the target device. Using the application programming interface and the other downloaded files, the remote user can test the target device, analyze the results, and even modify the test conditions without recourse to the testing harness. The arrangement provides a capability for a party who is not privileged to know details of the testing harness to practically evaluate and modify the design-under-test using a standalone testing application.
