Title: Improvements in and relating to a process and apparatus for the production of thin deposits upon a support by decomposition of a gaseous material
IPC: C23C16/44
Filed: 1953-06-10
Abstract: 760,328. Coating with metals. ERIE RESISTOR, Ltd., and DREWETT, A. F. June 4 1954 [June 10 1953], No. 15988/53. Class 82(2) [Also in Group XXXVI] In a process for the production of a thin deposit upon a support by decomposition of a gaseous material at low pressure the rate of flow of said material for decomposition is controlled by means of a porous diaphragm, disc or plug of non-fibrous material which is chemically inert to said gaseous material. The invention is described with reference to producing cracked-on carbon, &c. resistors. In Fig. 1 vacuum tube electric furnace 25 is charged with ceramic rods and fed with hydrocarbon vapour (e.g. heptane, benzene or methane), through sintered glass disc 15, Fig. 2 fused in glass tube feed channel 16. The required rate of flow of the hydrocarbon vapour may be obtained by using a single disc 15 with part obstructed as at 21 by resin, dental cement, wax or paint or by using two discs in series 17, 18 or in parallel 19, 20. Throughout the coating period the furnace tube 25 is rocked by cam/lever 27/28 from motor 29 and the direction of flow of the hydrocarbon vapour through tube 25 is reversed from time to time by operating twoway valves 40, 42. The hydrocarbon may be introduced into the middle of tube 25 as at 45. Two or more loaded furnace tubes 25 may operate together fed from common hydrocarbon source 10 with vaporizing by heater chamber 14. If carbon-boron deposit is required the tube 25 also receives boron trichloride vapour from suitably duplicated source/control 50. The coated ceramic rods are withdrawn, e.g. after 10/120 minutes at 1000‹C., and further processed into completed resistors.

Title: Improvements relating to Apparatus for Making an Exposure on a Photosensitive Sheet.
IPC: G03G15/26
Filed: 1968-04-03
Abstract: 1,199,525. Exposing photo-sensitive sheets. ADDRESSOGRAPH-MULTIGRAPH CORP. April 3, 1968 [April 3, 1967], No.16077/68. Headings G2A and G2H. Apparatus for making an exposure on a photosensitive sheet comprises a copyboard 10 having a table 11 on which an original or several originals to be copied are centred; means (not shown) for moving the table and the originals thereon to the vertical exposure position shown in chain dot lines, Fig.1; an optical projection system - lens 19 and mirror 33 - for projecting an image of the original on to a horizontal image plane located above the exposure position; and transport means for delivering a photo-sensitive sheet 46, 47 or 48 into an exposure position on the image plane, the sheet being supported face downwards from the back, the transport means also causing the delivered sheet to dwell during exposure and then removing the sheet from the exposure position. As shown, the apparatus is suitable for electrostatic copying, being provided with a charging station 50, a developing station 64 and a fusing station 75, but the apparatus may be adapted for copying on to silver halide photo-sensitive sheets. In use, an operator selects the size sheet to be used, and this positions a probe carriage 53 relative to the mirror 33. The apparatus may be used for reducing, one-to-one copying, or enlarging, the position of the lens 19 being adjusted relative to a rod rail 30. Adjustment of the lens position automatically moves the mirror 33 and its associated probe carriage 53. The sheet of the selected size is conveyed to its exposure position on the image plane by a belt carriage 41. This comprises spaced belts which traverse the underside of a vacuum chamber housing 42 having a perforated bottom wall 43 against which the selected sheet is held by suction. The leading end of the sheet trips a micro-switch 54 mounted on the probe carriage 53 and the belts stop instantaneously while the exposure is made. For electrostatic copiers, excess developer may be brushed away by hand at a correction station 70 at which the developed sheet is stopped. Movement of the probe carriage relative to the mirror means that a sheet to be exposed will always be correctly centred relative to the mirror and hence with respect to the original.

Class 40(3) [Also in Group XL(a)] In an instrument for measuring the dose or dose power of X-ray, gamma ray or neutron radiation, two hollow electrodes positioned one inside the other and made of materials having different charge carrier emission when exposed to radioactive radiation are connected to an electrometer which measures the electromotive force produced when the electrodes are irradiated. In use as a pocket dosimeter the instrument comprises two sphere shaped electrodes 1 and 2 arranged concentrically and a filament electrometer 5, 16, which are housed in an evacuated cylindrical casing 6. The rate at which the capacity formed by the electrodes 1 and 2 and the electrometer is charged is determined by the radiation intensity and the travel of the filament 5 relative to a measuring scale 8 is observed via a magnifying lens 7. A shell 20 surrounding the electrodes is formed of a material in which the hard components of the primary radiation (neutron or gamma radiation) release a secondary radiation to which the electrodes can respond. A turning movement of a magnet 18, attached to a cap 17 which is rotatable about the end of the casing 6, is repeated inside the casing by a corresponding movement of a magnet 15. By this means the filament of the electrometer may be earthed or one of a number of resistors may be selectively connected across the electrometer to enable the instrument to perform dose-power measurements.
