Abstract: ABSTRACT          * IMPROVEMENTS IN THE EXTRUSION OF PLASTIC MATERIAL *             Food products particularly of meat are extruded cased under pressure. The extrusion pressure, and the energy in the extrudate, makes the circular cross-section the only stable one on emergence from the extrusion head.             In accordance with the present invention two unstable shapes, D-shaped as described are extruded each cased from its own extrusion head.  The heads are disposed closely adjacent back to back to as to have a generally circular overall profile.  An outer casing is fitted over the two heads.  On extrusion the two D-shaped pieces abut one another and the outer casing to preserve their shapes until stabilised by freezing.

Abstract: DIGITAL RADIO WITH SECURITY SYSTEM FOR SELECTIVE      ENABLING SOFTWARE CONTROLLED OPTIONS              ABSTRACT OF THE DISCLOSURE Different digital radio transceiver front panel escutcheon plate modules are provided for different optional transceiver configurations.  A security circuit is provided in each module in addition to user controls and associated circuitry.  The security circuit is connected to communicate serial data signals to and from a digital signal controller which is part of the main transceiver circuitry.  The controller is capable of performing any of various basic and optional functions under control of program control instructions stored in an associated non-volatile memory.  Upon initial application of power to the transceiver, the controller transmits a sequence of digital signals to the security circuit.  The security circuit permutes the sequence of signals into a different sequence, the specific permutation used being arbitrarily complex -- and dependent on transceiver "option" features to be enabled.  The security circuit communicates the permuted signal sequence back to the controller.  The controller enables (executes) portions of the program control instructions stored in its associated non-volatile memory and disables (does not execute) other portions of the stored program control instructions in response to the sequence received from the security circuit.

Abstract: ABSTRACT      Counterbalancing  mechanism  for  a garage door or other device in which a torsion spring end member is fastened  to a second  member   to  which  it  is  connected  during  normal operation of  the counterbalance  by cooperating interfitting elements on  the members which allow longitudinal movement of the end of the  spring during  a spring  adjusting operation.          The counterbalance  hardware includes  a self-locking winding mechanism  for  winding  or  unwinding  one  or  more torsion springs which operates to fix one end of the spring connected thereto  against  movement  during  normal  operation  of the counterbalance.   The structure  connecting the  ends of each torsion spring into the hardware is such that each end of the spring  is  always  connected  for  rotation  with either the torsion  shaft  of  the  counterbalance  or  the self-locking mechanism including  during the  adjustment or setting of the torsion in the springs.   The  mechanism is  used in  a novel method  of  setting  or  adjusting  torsion spring tension in which the door is initially in a down position with  the door unlocked and  springs unwound.  The springs are then wound to initially partly lift the door and  then unwound  to seat the door to  establish the  proper tension  in the  springs.  Two springs  are  connected  to  the  winding  mechanism  and are adjusted simultaneously.

At least one of the sets of jaws is movable toward and away from the other set of jaws. The method is achieved by feeding a base tube into the pair of separately actuated carrier jaws. The jaws are then closed to clamp the base tube on either side of the cutting device. After the base tube has been cut, the cutoff part of the tube is moved away a predetermined distance to enable the double-acting deburring device to be introduced between the cut ends of the base tube and cutoff part. When the deburring device is in place between the ends, the movement of the cutoff part of the tube is then reversed, whereby it contacts the deburring device which in turn contacts the base tube. Simultaneous deburring of both cut ends takes place, the jaws are unclamped and a new cycle is commenced.
