Title: Method of and apparatus for forming sheet metal blanks
IPC: B21D22/20
Filed: 1942-12-22
Abstract: 560,505. Cupping. MISFELDT, C. C. Dec. 22, 1942, No. 18201. [Class 83 (iv)] Sheets are cupped or drawn in a press with a step-by-step action. The upper die 16 is reciprocated with a short stroke by connecting rods 14 from eccentrics on the shaft 5 driven through the gear 7 connected to the shaft through a clutch designed to stop the press at the top of its stroke. The die plate 12 supports a series of cylinders 17 having pistons 21 connected by rods 22 to a draw ring 24. The spaces 18 are filled with oil and are separated from compressed air spaces 19 by floating pistons 20. The lower die 35 is supported by a flange 32 on a main piston 31 moving in a cylinder 30 formed in the base of the press. A fixed rod 47 extends up through the bottom of the main piston to a secondary piston 46 operating in a cylinder 42 formed in the main piston. A fixed partition 44 separates the cylinder 42 from an air cylinder 40 having a piston 39 that has rods 36 extending into recesses in the die that is not secured to the flange 32. A cam 65 driven by the shaft 5 opens valves 86, 63 during each upstroke of the die 16. Oil under pressure from a main pump P. passes by a four-way valve 71 and metering valves 67, 69 to the space above the piston 46 and the space 30 respectively. The step-bystep lifting of the die is mainly effected by the piston 46 the oil below the piston 31 being primarily for locking the die 35 in each advanced position. Air pockets 54 in the piston 31 act as a safety device in the event of the piston rising too high, and a relief valve 80 discharging at 81 to the sump prevents too high a pressure from developing in the supply line 72. The valve 83 is normally closed but opens when the line 61 is connected to pressure for the power return of the die 35 preparatory to afresh operation.. As the die 35 rises the draw ring rises with it, oil escaping from the cylinders 17 to the sump by a relief valve 93. The predetermined pressure is maintained by an auxiliary pump 96 ; is controlled by a four-way valve 95, that provides for raising the draw ring when required ; and is indicated at 92. The air chambers 40 and 19 are supplied from the air line 100 through valves 101, 103 and 105 and the floating pistons 20 assist in preventing excessive draw ring pressure. When the sheet is completely drawn the final press stroke imparts a bumping setting pressure on attainment of which a valve 87 operates a switch 89 to release the clutch and stop the press. The valves 71, 95, 86 and 63 are manually operated to re-set the press.

Title: Improvements in or relating to means for the estimation of small quantities of gaseous impurities in rare gases
Inventor: COCKETT ALFRED HORACE
IPC: F17C13/02
Filed: 1954-06-22
Abstract: 785,302. Photo-electric gas analyses. BRITISH OXYGEN CO., Ltd. June 22, 1955 [June 22, 1954; Sept. 30, 1954], Nos. 18289/54 and 28265/54. Drawings to Specification. Class 40 (3). [Also in Group XL (a) Small quantities of gaseous impurities in a rare gas are estimated by passing an electric discharge through the gas at low pressure and measuring photo-electrically the variation in colour and/or brightness of the discharge. The gas is passed through a discharge tube (see Group XL (a)) by using a vacuum pump connected to one end thereof, a fine adjustment valve being adapted to maintain the pressure within the tube at a predetermined low value. The photo-electric means comprises one or more photo-cells contained with the discharge tube in a light-tight casing, lined with reflecting or diffusing material and the output from the cell(s) is measured by a suitable instrument which may be calibrated so as to give a direct reading of the amount of impurity in the gas. Variable shunts may be employed to adjust the instrument sensitivity. The current generated in a cell by the passage of pure gas through the discharge tube may be neutralized by using a further cell, exact balance being obtained by adjusting a resistance in series. Compensation for temperature variation may be effected by connecting a thermistor in a Wheatstone bridge with three fixed resistance arms, applying to the bridge an e.m.f. proportional to the impurity concentration and adding the out-of-balance current to the photo-cell output. Sensitivity may be increased by adding to the rare gas a small known amount of another impurity.

In either arrangement, the arms at the ends of the shafts may be operated through a lost motion linkage, successively or differentially. The arms may be on one or both ends of the shafts. Alternate shafts may be linked at one side of the vehicle and connected with a corresponding wheel and the intermediate shafts may be linked and connected with a wheel at the other side.

Abstract: 1510884 Vehicle headlamps ROBERT BOSCH GmbH 6 May 1975 [19 Dec 1974] 18852/75 Heading F4R A light/dark boundary ABEF in the beam from a headlamp reduces dazzle to on-coming motorists and is produced by a mask 20, a refractive diffusing screen and a reflector 10 which is a paraboloid deformed to exhibit a substantially elliptical lateral cross-section. As shown in Fig. 2, the major axes of the ellipses in the reflector cross-sections lie in a plane 21 at 45 degrees to the vertical plane 13. The deformation of the paraboloid may be permanent or it may be produced by a force acting from either the rim of the diffusing screen or a tensioning wire which also supports the screen. Positioning of the light sources 30, 31 for dipped and main beam behind an asymmetrical mask 20 in such a deformed paraboloidal reflector produces a beam with displaced, horizontal light/dark boundary sections AB and EF with a separating shadow (Fig. 6, not shown). The shadow is illuminated by displacing images 35, 36, Fig. 8, of the light source by refracting prisms in the diffusing screen (Figs. 10, 12, 13, not shown) which results in the shaping section BE of the light/dark boundary. The beam shape would be laterally inverted for left hand driving.

Title: Improvements in or relating to the production of pictorial and other designs
IPC: B44F1/04
Filed: 1924-08-09
Abstract: 246,883. Kent, F. W. Aug. 9, 1924. Ornamenting.-In the production of pictorial and other designs for advertising &c. purposes. wherein the design or a part thereof is treated with transparent colours and backed by a metallic or other opaque lustrous background, the background is formed with an irregular or granular surface by rolling, embossing, or other treatment so that the design stands out with great brilliancy throughout a considerable angular range of view. In one method of production, a portion of the design is printed by a lithographic plate, half-tone, line, or other block in multi-colour or monochrome on a paper or card base. The part of the design which is to have a brilliant appearance is printed on a separate base having a lustrous surface such as silver leaf, treated with transparent colours, and mounted in its proper position.on the paper or card base either on the surface thereof or in an opening cut out of the card. The design may be finally coated with varnish. The framing of the lustrous surface is preferably effected before colouring. If the lustrous surface is metallic, it is preferably coated with gelatine before printing, and, if the transparent colours are of an aqueous nature, a second coating of gelatine. after printing and before colouring, is necessary. In another method of production, the lustrous surface is applied to the paper or card base before being printed and coloured. In a further method, the whole of the design is printed on a lustrous base and those parts required to stand out with greater brilliancy are treated with colours which are more transparent than the remainder of the design. Specification 8594/87 is referred to. One of the Provisional Specifications describes also photographic methods of producing the design. In one method, a photographic print is produced on a paper or card base having a lustrous coating, by a transfer process such as described in Specifications 164, 448 and 177,255, [both in Class 98 (ii), Photographic processes &c.]. The print is then coloured with dyes, inks, toning solution, or water or oil colours. In another method. instead of using the transfer process, the lustrous surface could be coated with the photographic emulsion.
