Title: Improvements in or relating to vacuum deposition apparatus
Inventor: BRADLEY EDWARD MICHAEL
IPC: H01F41/20
Filed: 1962-05-30
Abstract: <PICT:1004739/C6-C7/1> Vacuum deposition apparatus includes a substrate support plate, a fluid-conduction path arranged in thermally-conductive relationship with the support plate, means causing heating of the support plate during a heating period, and means operable during a cooling period to pass a cood fluid through the fluid-conduction path to cool the support plate.  As shown in Fig. 3, the apparatus comprises a bell-jar 2 sealed on to a base 3, a support plate 4 for a substrate 5, a crucible 7 for the material to be deposited which is evaporated by heating and a vacuum pump 8 connected to the base 3 by a pipe 9 for evacuation of the bell-jar 2. Other devices, e.g. means for heating the crucible, means for supporting plate 4, vapour control shields, masks and gates, are also preferably included.  A copper tube 12 extends in serpentine fashion over the upper surface of the plate 4 and is connected thereto by brazing, the ends 14, 15 of the tube extending through vacuum seals 18, 19 in the base 3.  The end 14 of the tube 12 is vented to atmosphere and the end 15 is connected through a heat exchanger 31 and a valve 21 to a cylinder 20 of nitrogen. The heat exchanger 31 includes a helical electrical element 44 supported on an insulated former 43 and attached to a power supply 48, a switch 49 being provided ; a variable output controller may also be provided to vary the current.  In operation nitrogen heated in the heat-exchanger 31 is passed through the tube 12 to heat the plate 4 during a heating period and by opening the electrical switch 49 cool nitrogen will pass through the tube 12 during a following cooling period.  Other gases may be used in place of nitrogen or a liquid may be used, e.g. silicone oil.  In modifications the element 44 may remain energized during the deposition of a succession of films, a by-pass being provided at the heat exchanger 31.  The serpentine fashioned part of the tube 12 may be replaced by a covered channel formed in the plate. The tube 12 may form part of a recirculatory system in which the end 14 of the tube is connected to a pump supplying the other end of the tube, means for cooling the fluid before it reaches the pump being provided, e.g. a coil of finned piping or a refrigerating coil through which the fluid is passed.  In another embodiment, Fig. 1 (not shown), the heat exchanger 31 is dispensed with, the plate 4 being heated by an electric element formed by enclosing an insulated resistance wire within a copper tube which is brazed to the plate 4. In a modification, Fig. 2 (not shown), the electric element is not brazed to the plate 4 but is positioned between two copper plates which are clamped to the plate 4.  One of the copper plates may be omitted, the element being brazed to the remaining copper plate.

Title: Improvements in tabulating machine
Filed: 1947-07-31
Abstract: 642,920. Statistical apparatus. REMING- TON RAND, Inc. July 31, 1947, No. 20835. Convention date, Dec. 4, 1940. [Class 106 (i)] [Also in Group XVI] In a tabulating machine comprising a series of type-bars set by a series of card-sensing devices, each type-bar and each sensing device has a slide extending transversely thereto, the sensing device slides are arranged to cross the type-bar slides perpendicularly and in parallel planes and each sensing device slide is operatively associated with a selected type-bar slide by interchangeable rigid connecting means. A simplified type of tabulator is disclosed operated manually by a handle 78, Fig. 5, or, in a modification, by an electric motor 154, Fig. 7. The stack of cards 10 is clamped by a spring-urged plate 42 against a supporting-plate 35 which is grooved to receive a feeding slide 48. The slide 48, Fig. 4, is operated from a cam 74 on the driving-shaft 70, through a lever 66, link 64, and lever 58, a picker lug on the slide drawing a single card from the stack and entering it between guides 54, Fig. 5, on a carrier 32. During this movement the picker lug passes along the horizontal portion of an inverted L-shaped slot 52 in the carrier; when this movement is completed the data positions in the card are in register with corresponding holes 34, Fig. 4, in the card carrier. The card and carrier are now lifted in guides 30 by the action of a second cam on the shaft 70 operating through a lever 88, bell-crank 86, and link 84, and during this movement sensing-fingers 110, Fig. 5, enter perforations in the card and, with support from the perforated back-plate, are then displaced vertically distances depending on the positions of the card perforations. Each sensing finger is integral with a horizontal slide 98, guided by grooved plates 104, and interchangeable rigid connecting rods 120, Fig. 6, transmit the movements to a further series of horizontal slides 116 disposed at right angles to the lower set and integral with type-bars 82. Thus, the type on the upper portions of the bars 82, Fig. 4, is selected in accordance with the card sensed, for printing on a sheet passing over a platen roller 126. The platen is mounted between side-plates 128 pivoted on a shaft 130, and the printing action is brought about by eccentric pins 136 rocking the platen towards the type-bars, suitable inking means being provided. A ratchet-wheel adjacent the platen roller co-operates with a stationary pawl to feed the record sheet. During the upward movement of the card carrier 32 the picker lug on the slide 48 moves in the vertical portion of the L-shaped slot 52. As the carrier moves down again the sensing-fingers, by virtue of their shape, are cammed out of the perforations, the slide 48 is returned, and the feeding of the next card pushes .the first card edgewise out of the machine.
