Inventor: RUBENS LOUIS CHARLES
IPC: B29C59/00
Filed: 1982-11-22
Granted: 1986-07-10
Abstract: A method for decreasing the density of a substantially closed-cell thermoplastic resin foam material by the secondary expansion thereof. The method comprises increasing the gas pressure within the cells, retaining that elevated cell pressure for prolonged periods and then heating the foam material above its heat plastifying temperature to cause secondary expansion thereof. In an example, a low density polyethylene material was foamed to produce a foam with a density of approximately 0.085 grams per cubic centimeter. This foam was then pressurized with nitrogen and afterward secondarily expanded to produce a foam with a density of approximately 0.036 grams per cubic centimeter.

IPC: H01H9/10
Filed: 1983-06-23
Granted: 1990-04-05
Abstract: A reusable control module mountable to a power-cartridge-operated interrupting module which includes a normally closed switch in shunt with a fuse. The control module houses a control circuit which ignites the power cartridge to open the switch. The control module includes two conductive shells threaded together to enclose the circuit, thereby providing a Faraday cage for the circuit and shielding the circuit from the environment. A current transformer is mounted in an exterior pocket in one of the shells over a mounting terminal thereon which extends out of the pocket to act as a single-turn primary for the transformer. The output of the transformer is connected to an input of the circuit. Circuit boards of the circuit are mounted within the shells, in part by a plastic plug, one end of which passes through one of the shells coaxially with a mounting neck. The other end of the plug has slots which engage and hold one edge of the boards. The plug contains a conductor connected to the output of the circuit. When the modules are moutned together via the neck, the conductor at the one end of the plug is electrically connected to the power cartridge and the shells can now carry the current in a protected circuit to the switch and the fuse. The plug is located on the axis of rotation of the shells when the shells are threaded together so that its holding and signal-carrying functions are not compromised.

Title: Method and apparatus for editing and for replay of digital audio data recorded on a magnetic tape
Inventor: LAGADEC ROGER DR
IPC: G11B27/28
Filed: 1984-07-23
Granted: 1988-08-04
Abstract: In producing an edited tape (31) the lead-in material up to a first edit point is separated from the lead-out material running from a second edit point by a space containing unwanted material and accommodating the actual or notional splice. The unwanted material ensures correct operation of error protection for all of the wanted material on replay. The first and second edit points are marked by codes placed on the tape (31) by a code processor (43) and supplementary head (42). During replay the digital data recovered from the tape by a head (32) is entered into a random access buffer store (34) under control of a write address generator (38) and read out to output electronics (37) under control of a read address generator (39) running at the audio sampling rate. The write address generator (38) normally runs at a rate corresponding to tape speed but the code processor detects the codes for first and second edit points and a control unit (51) stops the write address generator (38) between such points so as to discard the unwanted material. The store is then replenished by speeding up the tape by a comparator (40) and speed control unit (10) in an arrangement which preserves a constant relationship between the read and write addresses, i.e. a constant degree of filling of the memory (34).

Abstract: A number of subscriber terminals are coupled to information signal receivers and/or transmitters. Each terminal has several signal connectors with several terminal clamps for two transmission paths with mutually opposite transmission directions. Thus in an interference-free state a transmission path connects sequentially all terminals, in which a synchroniser is incorporated. Each terminal has a monitoring detector for the signal flow. Each terminal has a synchroniser and, on detecting interference, the synchroniser is actuated to transmit a test signal, which is read by each of the remaining terminals. The detector then interconnects the terminals and/or the synchroniser in dependence on the test signal receiving terminals and the content of the test signal.
