Abstract: An asphalt release agent for preventing hot road asphalt, especially polymer-modified asphalt, from sticking to surfaces of delivery truck beds is provided. The release agent includes a water-based mixture of polycycloaliphatic amines and polyalkylene glycols. The release agent is applied onto the truck beds to create a slippery non-stick surface so that the road asphalt which comes in contact with such truck bed surfaces will not adhere.

Abstract: A pulse code modulation (PCM) unit is connected to a bus in a computer system. Also, connected to the bus is a processor and memory. The PCM unit is connected to transmit and receive telephone lines. The PCM unit reads uncompressed PCM data from the memory over the bus and compresses the PCM data for transmission over the telephone line in a cycle steal operation, wherein the bus is not being used by the processor. The PCM receives compressed PCM data from the receive telephone line, decompresses it, and writes the decompressed PCM data to the memory in a cycle steal operation. In addition, selectivity of either .mu.-Law or A-Law conversion, selectivity of even bit inversion for A-Law conversion, and selectivity between the compressed/decompressed PCM data or raw data is provided on a per channel basis. Selectable linear gain is also provided.

Abstract: A pulse code modulation (PCM) time division multiplex (TDM) telephone exchange to which n telephone lines are sequentially connected during n respective sequential time slots. An unlimited number of phones may be connected together for conference purposes by means of a summation memory in which each conference storage location is used for accumulating the sum of message samples from one or more lines during a write-in cycle and supplying the sum of the message samples to one or more of the lines during a subsequent read-out cycle. The summation memory is indirectly addressed by a connection control memory. A portion of each message sample stored in a sample memory is subtracted from each sum of message samples read out during the same time slot from the summation memory, so that a speaker hears an attenuated sidetone version of his own voice.

Abstract: An uninflated unmounted tire is supported in a frame of the apparatus for engagement with a sealant applicator head that contacts the interior tire liner after a bead spreading device on the frame spreads apart the tire beads, and an elevator member on the frame raises the tire. The applicator head has a tire engaging profile corresponding to that of the tire and an elongated opening for which highly viscous, sticky sealant is discharged onto the tire liner under the tread in a layer of predetermined cross section as the tire is rotated on the frame past the applicator head. A complete coating of sealant is applied during one revolution of the tire, with the sealant having a butt joint, or an overlapping splice formed when the elevator member is lowered a predetermined amount by a drop-off mechanism as the tire completes one revolution of sealant application.

Abstract: The switching circuitry topology is arranged so that the transistors operate in a 1E mode, that is, the voltage across the switching transistors is no greater than the input voltage (E) and at the same time the noise voltage normally generated in regulating circuit arrangements employing transistor switching is greatly reduced. A filter inductor in the primary switching circuit protects the switching transistors from sudden current changes during overload and enables operation of the transistors below the 2E mode. Power is regulated by pulse width control of the switching transistors. One pair of switching transistors is arranged to control the direction of current through the transformer primary winding. Another pair of transistors is arranged for controlling the current in accordance with the width of applied switching pulses.

Abstract: Standard configuration a.c. power transformer core sections are combined with standard configuration solenoid winding sections to provide a saturable core transformer which is arranged to be driven into saturation by applied alternating and direct current energy with the control of variations in flux changes up to saturation exercised by the direct current flow. A center tapped primary winding is arranged on an I-shaped stack of transformer iron laminations for full-wave excitation. A C-shaped stack of laminations is arranged adjacent to the I-shaped stack and separated by an air gap whereby the primary winding also serves as an input filter choke. The core structure is completed by an E-shaped stack of laminations arranged adjacent to the I-shaped stack and separated by another air gap. Two solenoid windings are arranged on the outer legs of the E-shaped stack and connected to a capacitor for resonating the overall ferroresonant transformer circuit arrangement.

Abstract: Multi-contact electrical connector for connecting terminal pads on one panel-like member to terminal pads on another panel-like member comprises a generally U-shaped contact terminal strip. The strip is made up of a strip of thin plastic having spaced-apart spring metal contact terminals adhered to one external surface thereof. The edges of the strip are mounted on an elongated mounting bar of insulating material. The connector is located between the panel-like members with the spring contacts in alignment with corresponding terminal pads. The panel-like members are clamped in a pre-determined relationship so that the terminals are flexed and portions of the terminals on opposite sides of the strip are resiliently urged against the pads.

Abstract: This disclosure is for an Audio-Visual training device having both a projectable film tape and an audio tape with control indicia on the audio tape in addition to recorded audio messages. The tape indicia are used to control a small processor which governs both tape and film movement. A keyboard on the device is used to enter replies to queries to a user from the tape and film and the processor will determine both tape and film movement in response to the answer to a query. The system is capable of multiway branching to present to the viewer the proper information pertaining to his answer. Several counters are available to count trials, correct or incorrect responses, etc., and to control tape and film movement in accordance with the counter readings. A proctor light may be turned on to call for personal assistance and to lock up the machine when a student is in trouble and the program does not have the proper branch to clear up the difficulty.
