Patent GB-1403067-A (GB)
Title: Data transmission systems
Inventor: CAMERON IAN R F
IPC: H04L12/40
Filed: 1972-10-17
Abstract: 1403067 Digital transmissions; polling systems INTERNATIONAL BUSINESS MACHINES CORP 17 Oct 1972 47723/72 Heading H4P Two-way communication between a central processor 1 (Fig. 3) and a remote station 19 is through at least one intermediate station 17 or 18 which itself establishes data communication with the processor when it receives an end-oftransmission signal from the remote station 19. Thus each station in a chain 19, 18, 17 may transmit successively to the processor 1 over a single channel 8, in response to a single poll signal from 1 sent to remote station 19. In another chain of stations 12, 21, 13, 14, connected by a modem 15 to the channel 8, the station 21 is accorded a higher level of priority by making it responsive to end-of-transmission signals from either of the two end stations 13, 14, while making the latter responsive only to unique address and poll signals. Each station 21 (or 17, 18, 19) includes an outgoing transmitter and receiver (30, 28, Fig. 4, not shown) to pass the polling signal from the processor to the furthest station, and a return transmitter and receiver (38, 36) conveying to the processor the data transmitted by the remote station in response to the poll. When eventually the end-of-transmission signal from the adjacent downstream station is received (by 36) and identified by a decoder (42), a buffer register (24) is caused (by unit 26) to convey data (from 22) to a gate (44) and transmitter (38). When the station (21) is addressed by the processor to receive data therefrom, a decoder (34) recognizes the address and causes the unit (26) to make a gate (32) pass this data to the register (24) and the input-output device (22). In the event of failure, an emergency shunt (46) by-passes the station. If a downstream station fails, its "ready" signal (on line TR) disappears causing this station (21) to assume the role of end station.

Title: Control System for Vapour-Deposition Coating apparatus
IPC: C23C14/56
Filed: 1966-11-01
Abstract: 1,168,813. Automatic control of coating. UNITED STATES STEEL CORP. Nov.1, 1966 [Nov.10, 1965], No.48945/66. Heading G3R. In a system for coating a moving strip of material in a vacuum, the intensity of an electron beam heating metal in a crucible adjacent to the path of the strip is automatically controlled in dependence on the speed of the strip to keep the coating thickness constant. In Fig.1, strip 14 passing through an evacuated chamber 10 is coated on both sides with metal deposited from vapour generated by crucibles 17, 18. The crucibles are heated by beams from electron guns 19 which are suitably deflected by electromagnets 20. Each crucible has five electron beams arranged transversely relative to the direction of strip travel, those further from the centre of the strip being of greater power so as to produce a uniform coating. This distribution of power is produced by suitably biasing magnetic amplifiers controlling the supply to the gun filaments. Deviations of coating thickness are detected by gauges 23 which control, through systems including servos 60, three potentiometers, Fig. 1a (not shown), adjusting the HT and filament supplies and the rate of feed of wire 21 associated with the appropriate crucible. The automatically controlled quantities are suitably modified to suit the speed of the strip by applying the output of a tachometer generator 24 to the system controlling the three potentiometers. Manually adjusted potentiometers 63, 64 further modify the automatically controlled quantities in accordance with the width of strip and thickness of coating desired. Selector switches (not shown) are provided for modifying the automatically controlled quantities to suit the number of crucibles in use. One of the three servo-controlled potentiometers adjusts, through a saturable reactor, the datum of a closed loop system controlling the total HT power supplied to all five guns. A second potentiometer adjusts the datum of closed loop systems controlling the current supplies to the gun filaments. A Zener diode is arranged so that HT variations outside a predetermined range modify the filament currents. The third potentiometer adjusts the datum of a closed loop speed control system associated with a motor 56 so that wire 21 is fed to the crucible at a suitable rate. A current regulator 67 associated with electromagnets 20 is automatically varied in dependence on the HT power supplied to the guns. Tachometer generator 24 also modifies the "off" time of a photocell-operated timer 65 so that servo 60 is interrupted for periods sufficient to permit corrections at the crucible to be detected by gauge 23. The strip is pre-heated to a desired temperature by electron guns 15 the different powers of which are automatically controlled by a temperature detector 22 arranged in a control system similar to those provided for controlling the crucibles.

Title: Method and apparatus for fabricating cylindrical thermoplastic  sleeves
IPC: B29C65/00
Filed: 1974-04-24
Abstract: 1474622 Making cylindrical plastics sleeve; searing OWENS ILLINOIS Inc 24 April 1974 [25 April 1973] 50892/76 Headings B5A and B5K A cylindrical sleeve of plastics material is made by wrapping a sheet around a mandrel with the ends of the sheet overlapping, directing hot air between the overlapped ends to soften their facing surfaces, diverting the air away from the ends after softening has occurred, and finally pressing the ends into engagement to form a longitudinally extending seam by means of a sealing bar. The sleeve thus formed may be used in a process and apparatus for the manufacture of containers as disclosed in Specification 1,474,621. In the above mentioned application rectangular blanks are cut from a continuous sheet, separated, and fed to an assembly for making sleeves. The sleeves are transferred to a series of mandrels which form a station at which discs are applied to the ends of the mandrels. The mandrels subsequently pass a heating station, a station at which the discs are sealed to the ends of the sleeves which have been heat shrunk on to the mandrels, a station at which the containers thus formed are removed from the mandrels and rimmed, a pre-heating station, before returning to the sleeve applying station for a new cycle (see Fig. 5, not shown). In the preferred embodiment, the leading end of a blank 18 (or 118) is held by a vacuum slot 35 on a rotating mandrel 31 (131), rotation of the mandrel through 540 degrees causing the blank to wrap around the mandrel with its ends overlapping as in Fig. 8. During the wrapping operation the blank is held firm against the mandrel by a roller 436 and at the end of the wrapping operation hot air is directed from an elongated nozzle 427a (427) between the overlapped ends. Finally the hot air is diverted and a cold sealing bar 429 forwarded to effect a seal. A series of mandrels are located on a rotating turret and after a sleeve has been formed on each mandrel the turret moves the mandrel to a path coinciding with the path of mandrels upon which the sleeves are shrunk to shape. The nozzle 427 associated with each mandrel 131 is located at the upper end of a vertical hot air duct 428 and has an air diverting opening 427b selectively opened and closed by a pivoted cover 428 actuated by a spring biased link system 428h actuated by a follower 428m which runs around a fixed cam 428n. Each roller 436 and sealing bar 429 is mounted in a carriage assembly 435 carried at the end of a forwardly spring biased piston rod 430 the rear end of which engages a fixed cam 430b through a cam follower 430a. The roller is biased forwardly of the bar relative to the carriage assembly by a spring 437 so that when the carriage assembly is first forwarded only the roller contacts the sleeve and when the assembly is further forwarded the pressure of the roller is increased and the sealing bar is brought into operative contact with the sleeve.
