    摘要： 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. The flow restrictor may comprise an orifice or nozzle but preferably comprises a sintered metal plug having a predetermined porosity for the expected materials and flow conditions to which the flow controller will be exposed. Process gases to be controlled by the flow controller are tested to provide data sets of mass flow rates at selected temperatures for a range of differential pressures across a flow restrictor and a range of downstream pressures.

    摘要： 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.

    摘要： 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).

    摘要： 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.

    摘要： 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.
