Abstract: Provided herein are organic solvent-based processes for the removal of rubber from non-Hevea plants such as guayule shrubs. By the use of the processes, solid purified rubber can be obtained that contains 0.05-0.5 weight % dirt, 0.2-1.5 weight % ash, and 0.1-4 weight % resin (when it has been dried so as to contain 0.8 weight % volatile matter).

Abstract: A method for forming a polymer-filler composite having advantageous bound filler content, the method comprising (a) providing a guayule cement; (b) introducing particulate filler to the guayule cement to form a solution masterbatch; and (c) desolventizing the solution masterbatch to form a polymer-filler composite.

Abstract: A gas delivery system is provided comprising an electrical backplane, a system controller operatively coupled to the electrical backplane, and a plurality of mass flow controllers. Each mass flow controller includes respective mass flow control circuitry operatively coupled to the electrical backplane. The system controller and each mass flow control circuitry are physically mounted on the electrical backplane. The gas delivery system further comprises a pump/purge system to help eliminate pressure build up in the system and provide a quick stop to a flow process in the system. Accordingly, a row associated with a flow process may be evaluated so that a mass flow controller may be swapped out as needed.

Abstract: A fluid mass flow controller, particularly adapted for controlling mass flow rates of toxic and reactive gases used in semiconductor device fabrication, includes a control circuit connected to pressure sensors for sensing the differential pressure across a flow restrictor in the mass flow controller for controlling a valve to control the fluid mass flow rate to a setpoint. The control circuit compares the differential pressure with the downstream pressure at a measured temperature with a data set of a gas passing through the flow controller for a range of differential pressures and downstream pressures and adjusts the flow control rate accordingly. The flow controller is mechanically uncomplicated including a two part body for supporting the pressure sensors, a remotely controllable flow control valve and the flow restrictor.

Abstract: The new fabric according to the present invention provides a great advance over conventional tent fabrics of both the types discussed above and others. In particular, the fabric, according to the present invention, possesses improved strength and durability for withstanding the external and internal forces placed upon it while still maintaining an economical cost of manufacturing and a light enough weight to be maneuverable. The fabric advantageously possesses multiple nonwoven axes that bear the load placed on them by external and internal forces.

Abstract: This invention is a guard for preventing the vandalism of the keypad of a telephone. If the telephone is a pay telephone, the invention further prevents, thus preventing entry into the telephone money box from the upper housing area. The telephone guard, composed of an upper housing guard and a keypad guard, is secured by high strength visible fasteners to the upper housing of a pay telephone. The upper housing guard and keypad guard are mated tightly to prevent vandals from prying off the keypad guard. The thickness of the keypad guard is greater than the throw length of the push buttons of the keypad. Thus, the force of a blow to the keypad will be absorbed by the front of the guard rather than the push buttons.

Abstract: A process mass flow instrument for measuring the mass flow rate of a process fluid including a fluid inlet, a fluid outlet, a flow passage connecting the fluid inlet and the fluid outlet, a fluid flow sensor which provides a raw output signal corresponding to an unknown mass flow rate and a processor which contains an empirically derived conversion routine for converting the raw output signal to an adjusted signal indicating the mass flow rate of the process fluid. A method for determining an unknown mass flow using an empirically derived conversion function, the function being derived by correlating the output signals of a mass flow instrument sensing the flow of a calibration fluid with the output signals of the mass flow instrument sensing the flow of the process fluid.

Abstract: A scoop for picking up lubricant from the inner cylindrical surface of a peripheral ring of a disc or a shaft dipping into a sump of lubricant in which a deflector (32) is rockable between two positions. In the position illustrated in FIG. 1, the tip (37) of one arm of the deflector is adjacent the cylindrical surface (27) while the inner surface (38) of the other arm seals against the surface (28) on the body (14), a passage (44) being provided for the flow of lubricant. In the other position, for the opposite direction of rotation, the tip (35) is adjacent the surface (27) and the surfaces (30) and (40) provide a seal.

Abstract: A bearing, particularly a heavy duty bearing, in which lubrication is effected by lubricant being picked up on a disc (27,28) mounted on the bearing shaft (21), the disc having, at its periphery, an axially extending ring (35) on the inner and outer surface of which the lubricant forms a film. During start-up, lubricant on the outer surface is scraped off by an external scraper (57) and falls under gravity onto the bearing surface and as the speed increases, lubricant on the inner surface is picked up by a scoop (38,39) to produce a pressure head sufficient to pump the lubricant to a reservoir from which it flows to the bearing surface under gravity. The lubricant is pumped to the reservoir through an external cooler (62) and an external filter (66).

Abstract: A device for controlling the amount of time players occupy each of a plurality of tennis courts, while showing waiting players how long they must wait and which of the waiting players is to get the next available court. A central board has two dials for each court, one dial being set for the time when play is begun and the other dial being set for the time that the court will become available. The board has a sloping rack into which a tennis racket is placed by a member of each group waiting to play. Gravity tends to draw the sequentially placed rackets downward with the racket occupying the most downward position signifying the identity of the person who is to get the next available court. By inspection of the dials, the waiting players can tell when each of the courts is to become available.
