Abstract: ABSTRACT OF THE DISCLOSURE         A position indicator for automobiles, trucks, and other vehicles includes a numerical display of the vehicle position with respect to an interstate highway by providing a readout of the mile marker location of the vehicle.  The display is actuated by an electrical circuit including a presettable up/down counter in which the initial location of the vehicle with respect to a reference marker along the highway is stored.  Subsequent vehicle movement increments or decrements the stored count in response to the receipt of vehicle movement pulses from a pulse generator.  A calibration circuit is provided to accurately calibrate the system for different vehicles.  In one embodiment, a digital keyboard is provided for entering the initial vehicle position information.

Abstract: ABSTRACT OF THE DISCLOSURE                The gel range of acid-acting delayed-action gelling agents, such as sodium silicofluoride, in latex spread foam compounds which are to be gelled by subjecting them to a preliminary heat treatment prior to drying is substantially broadened by including a water-soluble ammonium or amine sulfamate in the compound.  At least 0.5 parts by weight of sulfamate should be used per 100 parts by weight of dry solids in the starting uncompounded latex.  It can be added to the latex at any time before or during the compounding step and it is preferably added with 0.5-1 part of a soap per part of sulfamate and also with sufficient ammonium hydroxide or other ammonium donor compound to maintain the pH of the compound latex composition at 9.5 or higher.

Abstract: ABSTRACT         A telephone switching system for telephone trunk and subscriber lines that carry voice and associated supervisory information signals.  The voice signals are received through one of a plurality of ports under the control of a port event pro-cessor, and are transferred through a switching arrangement under the control of a call processor for transmission through a second port.  The supervisory information is also received as sense supervisory information with the associated voice signals, and is sampled and stored in a port data store memory.  The call processor can retrieve or modify the supervisory information stored in the port data memory store, and can store control information in the port data store.   The port event processor enables the transfer of certain supervisory information as control supervisory information from the port data store for transmission with the associated voice signals through the respective port.  The port event processor also performs certain operations specified by the commands and supervisory information stored in the port data store memory.  The port event processor and port data store memory both operate under control of timing signals from a timing signal generator.  The timing signal generator generates timing signals of two frequencies.  The port data store memory samples the sense supervisory information signals at a rate dependent upon the higher frequency timing signal, and the port event processor controls the operation of the respective ports in response to the lower frequency timing signal.

Abstract: EXTENDABLE REACH-TYPE TRUCK TRAILER                 TONGUE HAVING INTERNALLY MOUNTED, PRESSURE-OPERATED FRICTION LOCKING APPARATUS                                       Abstract In an elongate truck trailer tongue assembly having hollow, inner and outer telescoping tongue members movable between shortened and extended tongue positions, a remotely controlled, pneumatically actuated friction shoe ismounted within the tongue to selectively lock the tongue members in either the shortened or extended position. The tongue members are tubular and have square-shaped cross sections, and the friction shoe is shaped and mounted so as to be supported by the inner tubular member and, when actuated, to bear against interior wall surfaces of the outer tubular member, frictionally locking the members against relative movement and rigidifying the tongue assembly so that it acts as a unitary structure between the trailer and towing tractor. Cooperating with the friction shoe is a pneumatically actuated, spring-biased safety pin assembly which is mounted on the inner tongue member and engages mating holes on the outer tongue member at the shortened and extended tongue positions, to provide a backup lock for the tongue assembly should there be a loss of air pressure to the pneumatically actuated friction shoe. The safety pin is normally held in a locked position by the spring bias and is withdrawn therefromwhenever the normally pressurized actuator of the friction shoe is vented to allow telescoping of the tongue members so as to adjust the tongue length. In analternative embodiment, the friction shoe is actuated by a pair of hydraulic cylinders powered by a hydraulic fluid that is pressurized via an air-to-hydraulic pressure converter mounted inside the hollow tongue members.
