Filed: 1971-04-19
Abstract: 1284049 Cartridge-actuated fastener driving tools IMPEX-ESSEN VERTRIEB VON WERKZEUGEN GmbH 19 April 1971 [30 May 1970] 26783/71 Heading B4C A cartridge-actuated fastener driving tool comprises a thrust plunger 2 displaceable by the combustion gases from a detonated cartridge 3, the thrust plunger 2 having its rearward end arranged to be received in a propulsion chamber 1<SP>1</SP>. A cartridge chamber 5 issues into the propulsion chamber 1<SP>1</SP> and receives a cartridge 3. The base 3<SP>1</SP> of the cartridge faces towards the propulsion chamber 1<SP>1</SP> so that the cartridge case is ejected into the propulsion chamber by gas pressure after detonation. Desired rupture areas for the cartridge case in the form of three inclined slots 2<SP>1</SP> are provided in the wall of the cartridge chamber adjacent to the propulsion chamber, so that internal/external pressure can be quickly equalized when the tool is operated. One side wall 2<SP>11</SP> of each slot 2<SP>1</SP> meets the cartridge chamber wall to form a sharp edge, and the other side wall 2<SP>111</SP> meets the chamber wall in a smooth curve. The cartridge thus ruptures along the sharp edge and further splitting and disintegration are prevented.

Title: Improvements in or relating to the treatment of mats for use in the casting of stereotype plates
IPC: B41D1/00
Filed: 1931-09-25
Abstract: 385,371. Printing-surfaces. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Goss Printing Press Co. ; 1535, South Paulina Street, Chicago, U.S.A.) Sept. 25, 1931, No. 26792. [Class 100 (ii).] Stereotype.-A method of producing a set of matrices for casting multicolour stereotype plates includes applying gauging devices to the set and making in registered position on each matrix a mark which is produced in the casting of the plate and which mark serves to position uniformly all the cast plates of the set in a finishing machine. The matrices m<1> .. m<4> are laid in serial order upon the table of the apparatus to receive a number of registration marks applied by means of a gauging device. This latter consists of a frame 11, mounted for slidable movement along a rod 15 about which it also pivots. Along guideways 20, 21 on the frame 11, blocks 28, 29, 54, 55 slide, to carry rods 27, 53 to any desired position transversely of the table, the blocks being clamped in position by screws 35. The rods 27, 53 support sliding blocks 39, 40, 51, 52 which may be clamped in any desired position on the rods by screws 45. The blocks 39, 40, 51, 52 carry spring-biased centrepunch-like devices 43, which when actuated by hand will impress marks on each of the matrices which will be reproduced on the cast plates. In order that any one of a series of matrices may be shrunk by heat, electric heating elements 59 are provided each set being governed by a separate switch 60. Right-angled slots 63 .. 66 enable the corners of the matrices to be marked for trimming purposes. Hand-operated spring- biased punches 75, at three of the corners, enable perforations to be punched through the matrices to ensure accurate mutual positioning of each matrix in the stereotype casting- chamber. The co-operating die-block for each punch 75 is preferably pivotally connected to the table so that it may be swung into an inoperative position. Spring-biased punches 90 may also be provided to punch holes in the matrices, which will produce designs on the cast plates for use in registering all the plates of a set in a finishing-machine preparatory to trimming and shaping. In order that a record for future reference of the position of all the gauging means for a particular set of matrices may be kept, a portion of a roll of transparent paper &c. 97 is drawn across the frame, each of the punches producing a mark in the paper &c. which is then rolled on to a roller 105 and filed away. Specification 385,678 is referred to.

Abstract: <PICT:0866333/III/1> In a method of providing a glass sheet with a non-uniform metal oxide film by spraying on to the sheet heated to a temperature above 400 DEG F. and below the softening temperature of the sheet a film forming composition capable of producing a metal oxide film thereon, the sheet is oriented in a fixed plane, the spray is applied from a point of origin spaced from the plane of the sheet to a portion of the sheet, the spray is maintained about a central p axis having a fixed oblique angular relationship to the plane of the sheet and relative motion is provided between the heated oriented sheet and the spray transverse to a line which is the projection of the central axis of the spray on the sheet so that a film of non-uniform thickness is formed on the sheet, the thickness varying from a minimum along the line of intersection from an edge of said spray traversing the shortest possible straight line distance from the origin of the spray to the coated portion and increasing to a maximum along an edge of the sheet included in the portion directly exposed to the spray.  A preferred filming composition is one which produces a film containing cobalt oxide as a major ingredient with optionally nickel oxide, iron oxide, and tin oxide as minor ingredients.  As shown, apparatus for carrying out the process comprises a pair of spray guns 30, Fig. 2, carried on vertical posts 32.  The spray guns are urged upwardly by springs 34 against a curved cam rail 46 forming part of the carriage 40 conveying the sheet past the spray guns.  Preferably one of the spray guns is directed upwards at an angle of about 30 degrees to the plane of the glass sheet and the other spray gun at an angle less than 30 degrees.  Each gun carries a shield 38 to delineate one boundary of the spray.  The shape of the cam rail 46 is such that the boundary produced when the sheet is subsequently bent will be approximately a straight line.  In an alternative form of apparatus, Fig. 5, the glass sheet 10 is horizontal and the spray is applied thereto at an acute angle.  A baffle sheet 66 is used to prevent drippings from the spray guns contacting the sheet.  Specifications 704,793 and 822,295 also are referred to.

Abstract: 414,918. Separating gases by liquefaction. AIR REDUCTION CO., Inc., 60, East 42nd Street, New York, U.S.A.- (Assignees of Nuys, C. C. Van ; Cranford, New Jersey, U.S.A.) Oct. 3, 1933, No. 27226. Convention date, Oct. 27, 1932. [Class 8 (ii).] In the separation and recovery of ethylene from gas mixtures, the mixture, after cooling in an exchanger 8 by the separated outflowing products, passes into the lower part of a column 5 wherein it is partly liquefied, the liquid collecting in the bottom and the vapour rising through tubes 14 wherein further condensation of less volatile constituents occurs and passing off by a pipe 16 to the second column 6. The liquid containing ethylene passes to a separator 43 wherein some vaporization occurs, the residual liquid being delivered through a valved pipe 50 to the upper rectifying portion of column 5 while the vapour is led in part through a valved pipe 45 to a condenser 48 in this rectifier and in part through a pipe 44 to the corresponding rectifying portion of column 6. The vapour entering at the lower part of column 6 is partly liquefied with " backward return " in pipes 18 ; the vaporous porton flows through pipe 20, exchanger 27 and condenser 29 to a valved pipe 34 delivering it as liquid to the top of the second rectifier. The liquid portion flows through an exchanger 22 and a valved pipe to the bottom of the rectifier. Ethylene liquid freed from more volatile constituents collects around the base of the pipes 18, and the more volatile gases flow off at the top of the column where after cooling the exchangers 31, 27, 22 they pass off through exchanger 8. The liquid ethylene or its vapour is drawn off by a pipe 52 or 54 and delivered after expansion to the first rectifier, from the top of which ethylene flows off as gas through pipe 57. A portion of this gas may be recompressed in a compressor 62, cooled in exchanger 60 and delivered to condenser 48.

Abstract: 722,713. Electric dynamometer. HEENAN & FROUDE, Ltd. Nov. 24, 1952 [Nov. 22, 1951], No. 27381/51. Class 40 (1) An absorption dynamometer D (Fig. 1) measures torque by controlling the current in a coil c attached to the end of an arm A rotating with the dynamometer drum, by varying the capacity between two plates F, M, one of which F is fixed, and the other M is attached to the arm A, the current in the coil c being measured by the force exerted on a spring- loaded armature S<SP>1</SP> attached to a spring balance S. The system is initially balanced with full exciting current in the coil c. Movement of the arm A due to an applied torque decreases the capacity between the plates M, F, thereby increasing the voltage fed by a crystal-controlled oscillator V 1 , V 2  (Fig. 3) to a balanced amplifier V 3 -V 5 , the  double triode output valve V, controlling the grid-cathode relationship of a thyratron V., whereby the nett current through coil c is reduced, to compensate for the applied torque, and is indicated on the spring balance S: Damping is produced mechanically by a dashpot D', and electrically by a pick-up coil F'. To increase the range, the torque to be measured may be partly counterbalanced by weights D<SP>1</SP>.

[Also in Group XXII] In a machine tool, power is supplied to resist the traverse movement of a slide to eliminate backlash in the traverse drive. In a broaching- machine, a slide 10 bearing a rack 12 is driven on its working stroke P by a motor 30 driving through a controllable-torque clutch 31, reduction gearing 32 and a pinion 13 and on its idle stroke R by a motor 40, a similar clutch 41, reduction gearing 42 and a pinion 14. Both motors 30 and 40 are run continuously unidirectionally. Auxiliary controllable - torque clutches ARD, BRD are provided so that, on the working stroke, the motor 40 may be used to provide a controlled resisting force to eliminate backlash. On the idle stroke, the motor 30 may be used to eliminate any resistance to the movement of the slide. The motor 40 is used during a working stroke either to reduce the drag of the idle stroke drive by engagement of the clutch BRD, or if the resistance provided by the idle stroke drive is insufficient even with the clutch BRD disengaged, to provide a positive reverse drive by engagement of the clutch 41. The clutches may be of the hysteresis or magnetic type or controllable electrical, mechanical or hydraulic type.
