Abstract: 1431585 Multiplex data transmission INTERNATIONAL BUSINESS MACHINES CORP 3 July 1973 [10 July 1972] 31689/73 Headings H4P and H4L In a time multiplex data transmission system wherein information, transmitted in variable length frames, is distributed to selected terminals, each frame consists of a synchronizing character followed by address information, followed by one fixed length unit of information for each channel. Data received on line 1 is demodulated in MODEM 2 and is fed to a reception control unit 10 (detailed in Fig. 3, not shown). Each of the terminals, e.g. T i , to which data is to be passed includes a shift register 5 and by-pass switch 4, the registers of all terminals being connected in series to the unit 10. The address information of a frame is detected by unit 10, which produces signals to open the switch 4 in all terminals which are to receive data during that frame and this data is then shifted through the series connected registers, until each register contains its relevant data unit. A further control signal then reads out the contents of each register into its associated memory store 6. The contents of each memory are then serialized in unit 7 and fed to the related MODEM 8. For transmission in the reverse direction, data from the terminal lines, e.g. line 11, is fed via MODEM 8 the memory 13 to another register 14 shunted a further switch 15. The switches 15 of all registers 14 containing data are then opened by transmission unit 20 (detailed in Fig. 5, not shown) and their contents are read out and assembled into frames together with address signals and synchronizing signals.

[Also in Division H1] An apparatus for continuously treating a web of plastic film to improve the surface properties thereof for imprinting purposes comprises at least one pair of stationary electrodes disposed in parallel spaced relationship to provide a gap therebetween, means to produce high voltage stress, accompanied by corona discharge, in said gap and means to pass a film through said gap, the pair of electrodes including a first electrode and a second electrode presenting a smooth guide surface spaced with a gap from the first electrode to support the film and to make a firm and complete contact with the whole of one surface of the film passing through the gap with the free surface of the film at a predetermined spacing from the first electrode, whereby only the free surface of the film passing through the gap is subjected to the treatment. The second electrode includes a flat plate of dielectric material mounted in one of the electrodes to provide a smooth guide surface which deflects the film out of a linear path between a pair of guide means to ensure the firm and complete overall contact of one surface of the film with the guide surface and support of the film thereby. The dielectric material may be glass having smooth lead-in and lead-out edges for the film. The first electrode may present a flat face opposite the guide surface of dielectric material. The apparatus may be provided with guide means, e.g. rollers, to guide the film through the apparatus and the guide surface of the second electrode may deflect the film out of a linear path between a pair of such guide means to ensure the required contact of one surface of the film with guide surface and the support of the film by this surface. One electrode may be mounted on carrier means for swing movement of the electrode between its in-use position and an out-of-use position removed from proximity to the other electrode, e.g. to facilitate introduction of fresh film into the apparatus prior to starting up the treatment. The apparatus may be provided with two pairs of electrodes arranged in tandem to treat both surfaces of the film, one surface being treated after the other.

Title: A process and apparatus for producing homopolymers copolymers and telomers of ethylene
IPC: C08F10/00
Filed: 1959-09-22
Abstract: In the production of solid polyethylene (or a copolymer or telomer thereof) in a reactor at a temperature above 100 DEG C. and a pressure above 500 atmospheres, a physical parameter (e.g. temperature) is sensed successively in each of a plurality of zones in the reactor, and the product is directed away from the receiver when the parameter in any of the zones exceeds a predetermined value. This avoids contamination of the product with carbon due to decomposition if the temperature should rise excessively in any of the zones.  In an example, the reactor is a tube operating at 20,000-40,000 p.s.i.g. and maintained at 140 DEG -300 DEG C. by a fluid jacket.  The temperatures at points along the axis of the tube are sensed by thermocouples and displayed on a cathode-ray tube.  By means of an electrical circuit (see Group XXXVIII), a valve is operated to divert the product if the temperature at any of the thermocouples should exceed 500 DEG C., even momentarily.  The other constituents of the copolymers and telomers are listed. Specification 471,590 is referred to.
