Abstract: MINERAL FILLED SEALS FOR GALVANIC CELLS                 ABSTRACT        Mineral filled polypropylene (as a preferred embodiment, but also filled thermoplastic material that is inert to electrolyte, such as poly-propylene, polyethylene, copolymers thereof, and nylon) is used  for injection molded seals for galvanic cells.  The mineral is generally talc, (anhydrous magnesium silicate) but may be calcium carbonate or mica, or other electrolyte-inert material.  The use of such material provides a seal through which hydrogen generated as a result of internal corrosion in the cell will permeate; and particularly so as to provide better molding conditions and wider tolerances of mechanical design.  At the same time, since the bursting or rupture strength of a membrane of filled thermo-plastic material is lower and can be more easily predicted and controlled, and since a filled thermoplastic membrane will stretch less before rupture, a lower membrane bursting headroom may be designed for, and a larger volume of active material may be installed in the cell.  Due to the lower coefficient of linear thermal expansion and the higher compressive strength of filled thermoplastic material, the cells may be more effec-tively sealed.

Abstract: ABSTRACT            A pipe of thermoplastic polymer, e.g. polyvinylchloride is extruded by an extruder comprising an extrusion die  (2) having a moulding end part (2a) with heating elements(11)located about said end part. The wall thickness of the pipe is controlled in order to obtain a pipe of a substantially even wall thickness. For said control the wall thickness of the extruded pipe is measured at 360 points equally distributed over the circumference and moreover the average is determined in eight measuring sectors comprising 45 measuring points per sector. The average of the measuring values of one measuring sector is compared with the circumferential average of the 360 points, the deviation o  the desired wall thickness in said one sector being counter balanced by the action of the heating elements. In a prefered  embodiment a polyvinylchloride pipe obtained by means of an  two screw extruder presents an even wall thickness over the circumference.

Abstract: ABSTRACT OF THE DISCLOSURE         In a communication system, the user can be instructed by a speech message to execute an operation according to the procedure for each of various different services.  The switching system within the communication system identifies the kind of service which the user wants and then supplies speech information in a conversational mode to the communication terminal device, thereby instructing the user to execute an operation procedure for the service on the communication terminal device.  Therefore, the user can enjoy a desired service even if he has no preliminary knowledge of the operation procedure  for the service.

Abstract: SURGICAL STAPLING INSTRUMENT         WITH JAW CLAMPING MECHANISM     Abstract A surgical stapling instrument suitable for performing a gastrointestinal anastomosis is provided.          The stapling instrument incorporates a jaw clamping mechanism which applies clamping forces to its jaw members to resist the forces exerted on the anvil and staple cartridge carrying portions of the jaw members when the staples are formed.  Preferably, the stapling instrument includes a pair of elongate jaw members, one of which supports a staple cartridge adapted to receive at least two laterally spaced longitudinal rows of staples, and the other provided with an anvil adapted to form the staples.  A pusher bar and knife blade assembly is slidable longitudinally relative to the jaw members to sequentially drive the staples from the cartridge and form the staples against the anvil to produce a pair of laterally spaced rows in the tissue.  The pusher bar and knife blade assembly includes a knife blade for cutting the tissue along a line between the longitudinal staple rows.  A latching mechanism is provided for latching the jaw members together at an intermediate position therealong adjacent to the staple cartridge and the anvil.  In addition, a cam mechanism is provided for urging the jaw members apart at a position remote from the latching mechanism to resist the forces exerted on the staple cartridge and anvil when the pusher bar and knife blade assembly is actuated to staple and cut the tissue gripped between the jaw members.

Abstract: F. 0285-169 IMPROVED VIDEO ENCRYPTION SYSTEM                             Abstract of the Disclosure An encrypted video distribution system includes a signal originating station which distributes television signals in a format unrecoverable by a standard television receiver.  In particular, the normally occurring vertical and horizonal synchronizing pulses are deleted and, optionally also, video information is selectively inverted about a voltage reference potential intermediate the black and white levels.  To permit synchronization restoration, a keying pulse is transmitted once each video field, and a synchronizing digital code burst transmitted once each frame - all at a fixed, predetermined intra-frame timed relationship.   At each authorized subscriber location, the keying pulse and digital code burst are employed to lock a receiver frame clock which derivatively gives rise to all requisite recep-tion-permitting synchronizing pulses.  The transmitted information also contains information sufficient to restore the inverted video program content.

Abstract: ABSTRACT OF THE DISCLOSURE        An  improved  offshore  terminal is described, of the  type  that includes a riser loosely anchored at the sea  floor  so  its  upper  end  can  extend from a deep underwater  level up to the surface to moor a tanker and transfer  hydrocarbons  to  it.  A weight hangs from the lower  end  of  the  column  to improved dynamic mooring and,  where  the riser is disconnected to limit the sink depth  of  the  riser.    For  movement  to the deployed positon,  the  riser  is  lifted  by  extending  a  line downwardly  from  a  winch  on  the  vessel,  through  a central  hole  in the connector frame down to the top of the  riser,  the  line  being  pulled to raise the riser until  its upper end lies within the central hole of the connector frame.    A  perforated  upper portion of the riser  then  is  in  fluid  communication with the inner portion  of  a  fluid  swivel,  so that hydrocarbons can pass  out  of  a  conduit  within the riser and into the swivel.

Abstract: Abstract of the Disclosure Apparatus for filling containers with two pro-ducts from different sources, using a rotating volumetric filler which picks up first one product then the other, and discharges them both simultaneously into a container.          The filler uses a pair of concentric pistons, the central one of which is retracted to pick up the first product as it rotates over an arcuate slot beneath which the first product is stored; the outer, cylindrical piston is then retracted to pick up the second product as it rotates over another arcuate slot beneath which the second slot is located.  Both pistons are later extended simultan-eously to discharge the combined product into the con-tainer.  Since the two products picked up by the succes-sive retractions of the two pistons are held beside each other, a more uniform mixture of the two products is ob-tained than if they are picked up one above the other by a single piston.
