Filed: 1921-11-17
Abstract: 172,938. Bohn & Herber, Maschinenfabrik und Eisengiesserei. Dec. 13, 1920, [Convention date]. Sheet - feed tables; registering - devices. - Sheets are fed to the impression cylinder of an oscillating-cylinder printing-machine by the aid of a pivoted feed-table 1 fitted with guides for registering the sheets laterally and a fixed front stop 3 for obtaining the longitudinal register. The registered sheet 2 is held by a gripper 4 to the table 1, which is then lowered to bring the front edge of the sheet in contact with the impression 6 as the latter is completing its movement in a clockwise direction. Prior to the completion of this movement the front edge of the sheet is engaged and bent to a slight extent by a registering device 5 in connection with the grippers of cylinders 6, and the gripper member 7 grips the sheet subsequently. The gripper 4 then releases the sheet, preferably at the time of reversal of the motion of cylinder 6, but in any case by the time the cylinder 6 has returned to the position in which its front edge was engaged by the registering device 5.

Title: Improvements in or relating to a process for the production of patterned sheet material from raw pasteboard
IPC: B29C37/00
Filed: 1933-11-06
Abstract: 418,467. Coated fabrics. McKAY, R. F., Fort Dunlop, Birmingham.-(International Latex Processes, Ltd. ; 10, Lefebvre Street, St. Peter's Port, Guernsey.) Nov. 6, 1933, No. 30751. [Class 140.] Patterned sheet material suitable for floor coverings, automobile toppings, artificial leather &c. is made by printing a design on one or both sides of raw pasteboard (boards of unsized, felted, paper-making materials) with coloured solutions or aqueous dispersions of rubber or like material, and thereafter impregnating the sheet with a dispersion or solution of rubber &c. Chlorinated rubber, depolymerized rubber, polymerized butadienes or substituted butadienes may be used, and may be prevulcanized if desired. The design extends substantially through the sheet, and the penetration may be improved by adding wetting agents to the dispersions &c. The sheet may be compressed after impregnation. Before or after printing, the back of the sheet may be coated with linseed oil paint, rubber cement, rubber latex, or with sponge rubber by applying a foamed latex or a rubber composition containing a volatile salt such as ammonium carbonate. The face of the material may be coated with a solution or aqueous dispersion of cellulose ester, lacquer rubber &c. Such coated material may be embossed, and the surface coating hardened, e.g. rubber may be treated with bromine or bromine and sulphur chloride.

Abstract: 483,846. Discharge lamps. GENERAL ELECTRIC CO., Ltd., JENKINS.. H. G., RYDE. J. W., and WILSON, G. H. Nov. 11, 1936, No. 30788. [Class 39 (i)] Relates to electric discharge lamps with a discharge column more than 100 mm. long and consuming from 250 to 550 watts, enclosed with the discharge column vertical, in a sealed outer jacket coated on the interior with luminescent material. In order to prevent deterioration of the luminescent material by heat the jacket is filled with gas at such pressure that the temperature distribution on it is not seriously changed by convection (e.g. dry oxygen at 10 mm.) and is of such size and shape that when it is exposed in full operation to free air at 20‹ C. the temperature of a part of its surface on which 75 per cent of the radiation falls lies between 130 and 300‹ C. and does not vary by as much as 15‹ C. from point to point ; preferably the temperature does not vary over a part on which 90 per cent of the radiation falls by more than 50‹ C. The Figure shows a jacket 3 satisfying these conditions when used with a 400-watt lamp 1, the distance between the electrodes being 150 mm. The dotted curve shows the temperature distribution when the jacket 3 is filled with dry oxygen at 10 mm. pressure and surrounded by air at 18‹ C. Specification. 401,846, [Group XI], is referred to.

Filed: 1950-12-18
Abstract: 689,070. Vehicle brakes. DAIMLER-BENZ AKT.-GES. Dec. 18, 1950 [Dec. 17, 1949], No. 30848/50. Class 103 (i). A hand brake for a motor vehicle is provided with a servo device, preferably mechanical, and is characterized by the following features: (a) The hand brake lever is connected directly to the brakes through a lost-motion device which permits operation of the brakes by other means. (b) The hand brake lever is connected to the means for engaging and disengaging the servo device by a transmission incorporating a resilient device. (c) The driven part of the servo device is connected to the brakes through a lost-motion device which permits operation of the brakes by the hand lever. In the embodiment shown, a hand lever 20 is pivoted at 21 to the vehicle gear-box 22 and is connected through a pin-and-slot device 19 and a rod 18 to an arm 16 on the operating cam-shaft 15 of a brake 10. Also mounted on the cam-shaft 15 is a further arm 17 connected by a rod 45 through a slot 46 to a pin 77 on the driven member of a servo device 25 whereby the servo device can be used to assist the manual application of the brake. The driving member of the servo device 25 is driven through bevel wheels 66, 67 from the propeller shaft 26, and is brought into contact with the driven member by means of an axiallyslidable ring 48. The ring 48 is connected to the hand lever 20 by arms 70, 71 and 72 of a lever pivoted at 69 to the gear-box and by a spring unit 59, the spring of which transmits the force necessary to operate the servo device but allows movement of the hand lever to apply the brakes directly. The latter action is possible by virtue of the sliding of pin 77 in slot 46. The servo device is operative for either direction of motion of the vehicle. The Specification also describes and shows other embodiments in which the mechanical advantage of the linkage is increased.

Abstract: 604,006. Friction clutches. GERST, C. Nov. 20, 1945, No. 31228. [Class 80 (ii)] In a friction clutch the operating levers are arranged to lie within the rotating shifting means and to swing towards the axis of the clutch for engagement. A driving member 2 has internal splines engaging driving friction discs 11 which may be brought into engagement with the driven discs 10 which are splined at their centre to a hub 5 connected to a driven shaft 3. The pressure plate 16 is splined to the hub 5 and is backed by an adjustable ring member 19 screwed on a ring 20, which is free on the hub 5. An enlarged central portion 6 of the hub has a plurality of equi-spaced radial slots housing the rollers 25, and has keyed thereto a slidable collar 28 in which are pivoted the swinging clutch levers 27. The periphery of the collar 28 is ribbed to receive the shifting collar 34 provided with trunnions 35 for engagement with a shifting fork. Axial movement of the collar 35 causes the rollers 25 to trip the swinging levers 27, which rock towards the clutch axis and exert pressure on the plate 16 by the toggle action of the rollers 31 against the rings 20. In modifications the rollers 25 are replaced by wedge-shaped blocks and are made adjustable by screwing along the hub.
