Abstract: ABSTRACT      A central element for a filter press electrolysis cell which incorporates into a single cast unit made from a castable metal a planar barrier portion between the peripheral boundaries for the adjacent anolyte compartment and adjacent catholyte compartment of two electrolysis cells located on opposite sides of the planar barrier portion.  Also incorporated into the central cell element are anode bosses and cathode bosses extending outwardly from opposite sides of the planar barrier portion.  These bosses not only serve as mechanical supports for their respective anode and cathode but also serve as stand-off means and electrical current collectors. Simplicity of design coupled with incorporation of many functional elements into a single cast part eliminates cell warpage problems, inherent high voltage problems and membrane "hot spot" problems.

Abstract: ABSTRACT     A press for severing the meat adhering to bones from these bones has a press cavity provided with a press piston and a counter-piston, the mass of meat and bones introduced into the press cavity being pressed between said both pistons.          Passage openings formed of a perforated filter are provided in the wall of the press cavity, noting that the meat having been brought into the pasty condition by the press pressure can pass through this openings,  whereas the bones are re-tained. Both pistons have cylindrical sections and can be shifted in axial direction of the press cavity within this press cavity. The dimensions of the pistons are, as seen in radial direction, smaller than that of the press cavity. Both pistons have blunt, preferably slightly bomb-shaped front surfaces. One of the pistons releases during its retracting movement a discharge opening for discharging the pressed bones out of the press cavity. At least one of the pistons is provided with at least one abrading edge for the passage openings formed by the  perforated filter. The stroke of this piston provided with the abrading edge preferably extends over all passage openings of the perforated filter.

Abstract: IMPROVED ACCESS-ARBITRATIOM SCHEME            Abstract In a processing system that utilizes daisy-chain arbitration for controlling access to a shared resource by a plurality of using devices, a using device is allowed to issue an access request signal onto a request signal line shared in common with the other using devices only when it senses that the request line is idle.  Sensing is done during one clock period and issuance of the request signal is done during the next clock period.  The clock period exceeds the signal propagation delay across the request line.  Receipt by the arbitrator of a request signal is delayed by a clock period.  Access grant signals are daisy-chained by a grant line between the using devices, without synchronization at each device of issuance of the request signal and receipt of the grant signal, and without multiple sampling at each device of the grant signal.          Following receipt of a grant signal, a using device ceases to issue its request signal only upon detecting the end of the grant signal.

Abstract: ABSTRACT OF THE DISCLOSURE      An eyeglass assembly having removable temple pieces.  A spring arm has on one end a hinge pin and on the other end means for mounting the arm on the temple piece.  The arm is shiftable between an advanced position wherein the pin unites the knuckles to form a hinged connection, thereby attaching the temple pieces to the front frame piece, and a retracted position wherein the pin is removed from the knuckles.  This detaches the temple pieces from the front frame piece and enables use of the latter separately, for example, in a gas mask where the temple pieces would interfere with the proper placement of the mask.

Abstract: ABSTRACT OF THE DISCLOSURE         An  unmanned  vehicle  is  so  controlled  as  to travel along a guide line in response to command signals transmitted  from  a  fixed  host computer.   The steering misalignment  (offset)  of  the vehicle is corrected by a steering DC motor driven by an AC current, the duty ratio of which is adjusted by a steering motor chopper circuit. Since  dead  zones within  which  the  misalignment  is  no longer corrected and duty ratio calculating expression on which  chopper  duty  ratio  is determined according to a detected offset are both classified by vehicl speed, it is possible to stably correct vehicle steering misalignment at high response speed even when the vehicle is travelling at high speed along the guide line.   Further, when the dead  zone  and  the  calculating  expression  are  both classified by discriminating an initial offset from the succeeding offset, it is possible to not only to prevent the vehicle from travelling zigzag along the guide line, but also to reduce the number of rush currents generated in the chopper circuit.
