    摘要： A microprocessor-based audiometer for use with children. A color visual display unit is used to display an image digitally stored in memory or on disk drive to attract the childs attention and hold its concentration during testing.The child activates a response switch upon detecting the tones produced by audiometer to the generator. Correct responses are reinforced by progressive alteration of the displayed image to increasingly desirable states.

    摘要： Splice closures can be readily sealed by wrapping the cables with a mastic and then forming an end for a performed closure by placing the halves of a split ring about the mastic and drawing the halves closed by a toggle fastener including an arcuate leg connected at one end to one half and joined intermediate the fulcrum and handle of a lever supported on the other half to squeeze the mastic about the cables as the halves are drawn together. The closure may be sealed to the ring by a rolling O-ring.

    摘要： An end seal assembly is adapted to seal the space between at least one cable and a closure to restrict fluid transfer through the seal. The end seal assembly includes an end seal having a body formed from an elastic, flexible material. The body includes a core portion and an extended tail portion. The core portion has an outer peripheral surface, spaced ends, and a wall forming at least one cylindrical opening through the core portion. The cylindrical opening extends between the spaced ends. The wall has two edges communicating with the outer peripheral surface of the core portion to define between the two edges an entrance slot to the at least one of the cylindrical openings. The extended tail portion is integral with and extends from the outer peripheral surface of the core portion. Moreover, the tail portion has a surface tangential to the wall forming the at least one opening. In addition, the tail portion has sufficient length to wrap about the outer peripheral surface of the core portion to form a wrapped end seal such that the tail portion covers the entrance slot of the at least one opening and a cable to be placed therein. The assembly further includes a rigid collar having first and second collar portions that are pivotably interconnected. The first and second portions have inner surfaces that conform to and enclose the wrapped end seal to form an inner cavity between the wrapped end seal and the first and second portions of the collar. The collar also has an outer surface adapted to sealingly abut an end of the closure. Furthermore, the assembly provides for injection of a sealant composition to fill the inner cavity and to bond together the wrapped end seal, the cable (which is placed in the opening), and the rigid collar.

    摘要： A fiber optic splice closure for protecting the splice made into a transmission cable, containing a plurality of fibers which are to remain unsevered, comprises a base to which the cable is anchored and in which slack fibers in the uncut cable are looped and stored free of transverse barriers. The seal is made with the cables and the base by a mating cover provided with a second area to receive splice trays and slack fibers selected from the cable for splicing.

    摘要： A vehicle brake system for operating a spring applied, fluid pressure released brake. In order to assure that the brake is fully released before the vehicle is operated, the system requires the operator to perform two operations. He must move a manually operated hydraulic valve to the brake release position and in addition must close a normally open, momentary contact switch which actuates a second solenoid operated valve in series with the first valve to the brake release position. When pressure has built up in the brake actuator sufficiently to assure that it is fully released, a pressure sensor causes a hold-in circuit for the solenoid operated valve to be energized whereupon the operator can then release the momentary contact switch.
