Abstract: ABSTRACT OF THE DISCLOSURE      In equipment for wireless transmission of telephone calls between a stationary unit connected to a telephone line and a portable wireless telephone handset at a short distance from the stationary unit, all the pairs of units have access to a plurality of common duplex radio speech channels for transmitting the calls, and a common radio signalling channel for transmitting signals concerned with establishment and disconnection of the speech channels.          The radio speech channels are assigned after adaptive chan-nel scanning in that they are listened-into before a call and a channel is selected which is unoccupied.  A single speech channel is used for both transmission directions, which is enabled by time division and time compression.          The degree of time compression is adjustable in response to whether speech signals are present for transmission or not.          The equipment radio transmitters are adapted for either sending digital or analogue speech signals.  The equipment radio receivers are adapted for operation according to the homodyne principle.

Abstract: ABSTRACT A foam extrusion apparatus adapted to be positioned downstream of an extrusion die in an environmental control or vacuum chamber for remote monitoring of the thickness and profile of foam boards, planks and like extrudates soon after the extrudate exits the die and takes its final shape, is characterized by opposed, relatively narrow shoes on opposite sides of the extrudate path and respective carriages therefor which together are movable transversely with respect to the extrudate path by respective worms and translating nuts and a common worm drive. One shoe is operative to support the bottom surface of the extrudate in a predetermined position while the other shoe rides on the extrudate and is position monitored by a transducer operative then to provide an output signal representative of the spacing between the shoes, and thus the thickness of the extrudate passing between the shoes, to remote monitoring circuitry located outside of the vacuum chamber. Through operation of the common worm drive, extrudate thickness is measured at points along the width of the extrudate for overall thickness and profile monitoring. Quick and responsive die adjustments then are made in response to immediate readout of product thickness and profile data thereby to minimize off-specification or scrap product. Provision also is made for pivoting one of the shoes and respective carriage clear of the extrudate path such as in the case of a jam-up.

Abstract: ABSTRACT    A method of making a parallel programmed electronic matrix array includes forming at least one layer of a phase changeable material on a conductive substrate, the material preferably formed of amorphous material and having substan-tially nonconductive and comparatively high con-ductive states, and irradiating selected areas of the layer to convert them to the other state. Thereafter, in a preprogrammed embodiment, first and second sets of electrically conductive address lines are formed on respective opposite sides of the layer such that they cross each other at an angle to form a plurality of crossover points.  In a field programmable array, the selected areas are irradiated through one set of lines.     In accordance with another embodiment, the selected areas are irradiated through a mask.  One set of lines is preferably formed by removing portions of the conductive substrate.  The other can be formed by detecting the locations of the layer portions of one of the states and aligning the lines on the layer according to such detec-tion.     A diode structure can be formed with or in place of the phase changeable material.

Abstract: SLIDING DOOR LOCK                         Abstract A door lock for sliding doors of trucks, vans and the like includes an exterior handle assembly and an interior handle assembly for actuating components carried in an interior housing assembly.  The components include a pair of rotary latch bolts projecting  through  openings  formed  in  opposite  sides  of  the housing  assembly.   A pair  of  strikes  are  carried  on  spaced portions of a vehicle wall at locations on opposite sides of a vehicle access opening which is controlled by the door.   The door is movable between a latched-closed position wherein one of the latch bolts latchingly engages one of the strikes to hold the door closed, and a latched-open position wherein the other of the latch bolts latchingly engages the other of the strikes to hold the door open.  A thumb-operated lock control slide is carried  by  the  housing  assembly  and  provides one  means  for locking and unlocking the lock from inside the vehicle.  A key cylinder provides a means for moving the control slide between locked and unlocked positions  from outside  the vehicle.   The exterior handle assembly can be operated to unlatch the lock only when the control slide is in its unlocked position.  The interior  handle  assembly  can  be  operated  regardless  of  the position of  the  control  slide  to  release  latching engagement between either of the latch bolts and its associated strike.  A          "slam override" feature permits the lock bolts to be moved into latching engagement with the strikes regardless of the position of  the  lock  control  slide,  and  prevents  the  driver  from accidentally  locking  himself  out  of  his  vehicle  by  assuring that,  when either of the  latch bolts  engages  its  associated strike, the thumb-operated slide is maintained in or moved to its unlocked position.
