Abstract: ABSTRACT A separator, vertically movable upon the lengthwise shift of a cradle, effectuates joint action with a movable stop and pile pressing device in order to separate a sheet batch from a pile of sheets.  Simultaneously with rotraction of the movable stop, two batch pushers are actuated to feed the batch into a conveyor.  The motion of the cradle is achieved by means of a hydraulic cylinder.  The sheet pile is carried by a pile hoisting device and a new pile is maintained on a roller conveyor in order to ensure a continuous infeed of the sheet batches.  A roller conveyor allows the removal of the few sheets remaining after the last sheet batch of a pile has been fed in.  To this end, a flap controlled by a motor with an associated rack and pinion shifts a pallet perpendicularly to the direction of travel of the batches.

Abstract: PARISON MOLD-CORE APPARATUS                       ABSTRACT OF THE DISCLOSURE      Mold and core rod combination for forming a plastic parison for stretch/blowing into a plastic bottle com-prising a core rod with an end mated to the mold so as to permit formation of a parison  with a flat bottom wherein the bottom corners of the parison have a sharp taper.  The core rod is preferably shaped to include a shoulder having a substantially straight outer wall at the mouth end of the parison mold, and constructed and arranged with the mold to permit deposit of additional plastic at the inner wall of the shoulder of the parison.          The design of the mated mold and core rod combination is based on the recognition that in a continuous bottle forming process a particular area of the parison can be made hotter or cooler by increasing or decreasing the thickness of that area of the parison.  Parisons formed with the disclosed mold-core rod combination permit a deeper and longer stretch of the parison without tearing or deformation of the parison bottom or deformation or wrinkling at the shoulder of the finished bottle while providing essential wall strength.

Abstract: MULTIPLEX SECURITY SYSTEM USING REMOTE MICROPROCESSORS    ABSTRACT OF THE DISCLOSURE         A multiplex security system provides two-way data communications between a local panel and multiple microprocessor-based remote panels interconnected over a common data transmission line.  A second line provides two-way voice com-munications between the local and remote panels with automatic forwarding by an audio/data control selector to a central control unit via a single telephone line.  Two additional lines provide a common ground and transmit DC power from the local to the remote panels.  The remote panels include bus drivers connected to the communications line for transmitting both ASCII digital data messages and a higher voltage request or SRQ signal to the local panel when the remote panel has a message to transmit.  The local panel includes two separate receivers for distinguishing the request signal from digital data and a bus driver for transmitting data.  The local panel transmits a grant message which is superimposed over the request signal, reducing its voltage level to zero.  The remote panel has a receiver for receiving ASCII data from the local panel and for sensing the reduced voltage level to turn off the request signal.  The remote panels are assigned priorities by setting different switch numbers in each panel.   The switch numbers correspond to unique brief time slots in which each of  the  remote  panels  can  commence  transmitting.          Following a grant command, the remote panels count time  slots.   None  can  respond until  the  count equals its respective switch number, and then only if another panel has not already commenced trans-mitting.
