Title: An apparatus for continuous treatment of a continuous-length material with low temperature plasma
IPC: B29D7/01
Filed: 1981-06-18
Abstract: The apparatus comprises a plasma chamber 1 and a front and a rear preparatory vacuum chambers 8 and 9 which serve to introduce the film material F into and to lead the material out of he plasma chamber without permitting air intrusion into the plasma chamber from the atmosphere, wherein the vacuum chambers 8 and 9 are each divided into at least two (e.g. four) sealing chambers 8a-8d and 9a-9d, each being provided with a pair of opposing sealing rollers 10a-10d and 11a-11d. The low temperature plasma is generated in the plasma chamber by applying high frequency electric power to the drum-like rotatable cathode 4 and a plurality of rod-like anodes 5 surrounding the cathode and the film material F is led into the space between the cathode and the anodes in contact with the cathode to be transferred as the cathode rotates, with the aid of guide rollers 7. The electrodes and guide rollers are held on one of the side walls of the plasma chamber in cantilever fashion, the side wall being demountable and mountable upside down, and the other side wall is made a removable cover of the plasma chamber so as to facilitate film setting up and inspection or cleaning of the inside of the chamber. <IMAGE>

Title: Improvements in or Relating to the Making of Printing Plates
IPC: G03F1/90
Filed: 1981-07-10
Abstract: The invention concerns assembling a montage of a plurality of individual films (12) for exposure of the films to a printing plate.

Title: Index card filing system
Inventor: WHITEHEAD JOHN
IPC: B42F17/02
Filed: 1981-07-24
Abstract: In an index card filing system (10), the separators (15) supporting respective sets of index cards (16) can be removed from a cabinet in units (19) of three each, unit by unit. By pivoting two feet (25, 26) the individual units can be made free- standing, whichever way the separator members (15) lean. An auxiliary separator member (27), having no index strip unlike separator members (15), supports the set of index cards on the outside of one of the three separator members (15). A base support member prevents the separator member (15 and 27) from falling right over instead of just leaning. The cabinet for units of index cards has rails to prevent the separator members (15 and 27) of remaining units 19 from falling right over instead of just leaning, by engaging protruberances arranged in the sides of the cabinet. <IMAGE>

Title: Production of acyl fluorides by carbonylation
Inventor: TRIVEDI BHUPENDRA C
IPC: C07C51/04
Filed: 1982-06-04
Abstract: An acyl fluoride, e.g., isobutyryl fluoride, is formed by reacting carbon monoxide, an organic compound (e.g., propylene) and anhydrous hydrogen fluoride, in a liquid mixture while feeding the carbon monoxide and organic compound (e.g., propylene) into the liquid mixture's vapor phase which is maintained above the supercritical temperature of the vapor mixture at substantially the same rate as the carbon monoxide, organic compound (propylene) and anhydrous acid (hydrogen fluoride) react. The temperature is 40 to 90 DEG C and the pressure 109-340 bars. The final mole ratio of anhydrous hydrogen fluoride to organic compound in the reacting mixture is 1 to 100 moles of anhydrous hydrogen fluoride to 1 mole of organic compound and the mole ratio of carbon monoxide to organic compound is from 1 to 25 moles of carbon monoxide to 1 mole of organic compound.

Patent GB-2105241-A (GB)
Title: Stapling machine
Inventor: SMITH KENNETH MALCOLM
IPC: B42B4/00
Filed: 1982-09-02
Abstract: A stapling machine has stapling heads (18), each pivotally mounted so as to rise and fall into co-operation with a respective anvil in a fixed knife edge formed on plate (36). Sheet material is advanced over a platform (60A, B) to a position between the stapling heads and the knife edge so that it can be stapled and creased along the spine by means of a pair of bars (38) spring-loaded towards each other and pivoted so that the bars can be brought down onto the sheet material and press it down around the knife edge. The lower end of the movement of the bars can trip a microswitch to electrically operate the stapling heads, or the stapling heads can be separately manually operated. The bars can be arranged to grip the folded spine of the sheet material on the return movement, so as to present the spine for manual removal from between the bars. <IMAGE>

Title: Digital computers
Inventor: DARLINGTON JOHN
IPC: G06F9/44
Filed: 1982-10-06
Abstract: A digital computer has an addressable store 1, which may comprise segments 1a, 1b, etc. and a plurality of independent digital processing units 3a, 3b, etc. all communicating with the store 1 through a communication facility 2. Addresses (or identifiers corresponding to such addresses) in store 1 containing packets of digital data which require processing are held in a group of identifier stores 4a, 4b, etc. to which group the processing units all have access. Where processing results in the generation of fresh packets of data, addresses available for the storing of such data in store 1 are held in a second group of identifier stores 5a, 5b to which the processing units also have access. Controllers 6a, 6b, etc. and 7a, 7b, etc. ensure even distribution of identifier address among the stores of a group and act as interfaces between the identifier stores and the processing units. <IMAGE>

Title: Securing devices for turn bolts for moving panels
Inventor: GROVES MICHAEL HOWARD
IPC: E05B15/02
Filed: 1982-12-01
Abstract: A securing device 10 for a turn bolt 11, e.g. for a window or door is in the form of a shell moulded from a resilient plastics material, the edge portions of which provide a base and the central portions 16 of which are raised.
