IPC: F01B3/10
Filed: 1963-08-29
Abstract: 1,062,874. Hydrostatic transmissions. DOWTY TECHNICAL DEVELOPMENTS Ltd. Aug. 25, 1964 [Aug. 29, 1963], No. 34165/63. Headings F2C and F2D. The casings of a plurality of tilting head pump and/or motor units for a hydrostatic transmission are joined together for conjoint tilting movement about a single axis. As shown, Fig. 4, in a hydrostatic transmission a pair of motor units in a single casing 6 are hydraulically connected in parallel and are supplied with pressure liquid by a tilting head pump 1. The casing 6 is pivoted at 38, 43, 44, 41 to a fixed housing 14 and has valve plates 28, 29 which co-operate with rotatable cylinder blocks 47, 71 having axial cylinders 51, 73 co-operating with pistons 57, 79 pivotally connected to plates 65, 86 fast with output shafts 5, 17. The shafts 5, 17 are geared together at 19, 21 so that the two motors rotate at equal speeds in opposite directions. Ducts 58 in the piston connecting rods permit fluid from the working circuit to lubricate bearing plates 68, 87. Ports 55, 56, 77, 78 in valve plates 28, 29 are interconnected by ducts 97, 99 which terminate in a lug 91 which is pivotally connected by links 7, 8 to the pump. The links 7, 8 also transmit hydraulic fluid between the pump and motor units. In Figs. 5 and 6 (not shown), the output shafts of the motor units each carry a gear which meshes a gear on a separate driven shaft and thus each motor unit rotates in the same direction. In Figs. 7 and 8 (not shown), the output shafts of the motor units are geared together through an axially slidable idler, axial movement of which disconnects the output shafts. A valve is also provided between the valve plates so that one of the motors may be isolated hydraulically. This arrangement increases the range of output speeds by permitting the motors to be used in parallel for low speed high  torque operation and using one motor alone for high speed operation. In Fig. 10, the motor output shafts 5, 17 are geared at 151, 152, 155, 156 to the half-shafts 153, 157 of a motor vehicle and permit differential action. The differential action may be locked out by engaging a clutch 159 which connects the two half shafts. The multiple tilting head unit may include both pump and motor units in which case the cylinder blocks are parallel and the input and output shafts at an angle to each other.

Title: Improvements in or relating to sewing machines
IPC: D05B15/00
Filed: 1936-12-14
Abstract: 488,855. Sewing-machines. DEL-MAC SHOE PROCESS CORPORATION. Dec. 14, 1936, No. 34217. Convention date, Dec. 18, 1935. [Class 112] A chain-stitch machine for sewing an upper to the sole of a shoe while unsupported on a last comprises a fixed work support 100 and a movable support 102 both entering a stitchreceiving channel on the under side of the work, and a fixed rib 122 and a movable rib 128 on the presser foot entering a stitchreceiving groove on the upper side of the work opposite the channel on the under side. An awl 40 pierces the work, and a straight needle passes upwards through it, takes the thread from the looper 42, and then moves laterally towards the support 102 to feed the work. The needle bar 50 reciprocates in a guide block 52 secured to a rock shaft 54, by which the needle is oscillated in the line of feed of the work. A cast-off 38 is supported on a bar 70 reciprocating in the block 54. The movable support 102 moves with the needle in the line of feed and is rigid with the block 54. The presser foot 84 is held down by a leaf spring 88, and is lifted by a rock shaft 90 carrying a lifting lever 92 which operates through a self-adjusting locking device 96, 98, 99. The movable rib 128 on the presser foot is carried by a plate 124 pivoted on a vertical pin, so that it is moved aside during the feed movement of the needle. The presser foot lock comprises a spring-pressed pin 140, the end of which engages the top of a block 148 carried by the presser foot bar. The pin rests in a notch 168 in the block to permit the presser foot to yield slightly during the upward movement of the needle. During the feed movement of the needle, the pin 140 is disengaged from the block 148 by a cam lever 158 operated by a pin 162 on the lifting lever 92 when the latter is moved to lift the presser foot. The presser foot may be lifted by a treadle through a lever 172, which carries a plate 176 adapted to actuate the lever 158 for releasing the pin 140. A guard plate 190 covers the mechanism beneath the work, and serves as a guide for the sole to determine the angle at which the needle and awl pass through the work. A supporting horn 200 enters the interior of the shoe and is pivoted horizontally at 202 on an arm carried by a bracket 206 pivoted at 208, so that the horn is moved away from the work periodically to permit the feed movement of the work. A guard 230, 232 holds the shoe upper in advance of the sewing point against the shoulder of the insole to prevent it from being punched by the awl. The starting and stopping mechanism comprises a clutch 240 arranged to connect the pulley 46 to the crankshaft 44, and a brake shoe 244 engaging the hand wheel 242. These parts are controlled from a treadle by means of a clutch lever 246. In stopping the machine a two-armed lever 252 is forced by the lever 246 into engagement with a slot 258 in the hand wheel.

Title: Machine guard
Inventor: YARDLEY SIDNEY
IPC: F16P3/10
Filed: 1956-11-09
Abstract: 812,466. Machinery guards. JAGUAR CARS Ltd. Nov. 9, 1956, No. 34266/56. Class 80(4). In a machine in which the drive of the operating tool is controlled by a fluid-actuated member (e.g. the engagement of a clutch or release of a brake) a movable guard controls the supply of the actuating fluid so that the drive can only be effected when the guard is closed. In Fig. 1 two sliding guard parts 11, 12 carry flexible pipe portions 15, 16 which are connected respectively to a compressed-air source and to the fluid-actuated member controlling the drive. The ends of these pipes 15, 16 are provided with coacting coupling parts 17, 18, the part 17 having a valve with a projecting stem 19 and the part 18 having a socket 20 for receiving the valve stem 19. The valve stem 19 is spring- loaded at 42 (see Fig. 5) to project when the guard parts are open as in Fig. 1 to close axial and transverse passages 43, 70 therein. When the guard parts are brought together the stem 19 of coupling part 17 engages in the socket 20 of coupling part 18 and is pressed inwardly to open the passages 43, 70 to the inlet pipe 15 which can then pass the compressed air to pipe 16 and the fluid-actuated member for starting the drive. The pressure in pipe 16 is also utilized to operate a locking bolt which must be released before the guard can be opened. The release of such pressure-operated lock may be effected automatically at the end of each operational cycle of the machine as by a cam actuating a pressure release valve. A single sliding guard may be used instead of the two-part guard and may be of part-cylindrical form to move in a curved path.

Abstract: 399,045. Stereoscopic kinematography; projection screens. ARNULF, A., 13, Rue de Poissy, Paris. Dec. 5, 1932, No. 34391. Convention date, Dec. 4, 1931. [Classes 97 (i) and 98 (ii).] A device for taking and projecting still and motion pictures in relief comprises the combination of a film having cylindrical corrugations with an optical device having on its front and rear transparent faces corrugations of different radii so arranged that the image planes of the corrugations are coincident, the corrugations of the optical device being arranged parallel to those of the film when in use. For taking the arrangement shown in Fig. 3 may be used, in which 0<1> and 0<2> are objectives, F is the film and E the optical device. The device E may be constructed, as shown, of a block of transparent material having corrugations e<1>, e<2> on opposite faces and the common image plane o being formed as a diffusing surface. Alternatively, the surface of the block on one or both sides of the image plane may be corrugated or an air space may be formed on one side of the image plane. In a further form one series of corrugations may be concave so that the image plane lies outside the block. In this case one or other of the corrugated surfaces is striated to form a diffusing surface. For projection, an optical element similar to E forms the projection screen. In order to view the image by reflection one face of the screen may be rendered reflecting. In a modification the screen is formed with corrugations e<2>, e\ Fig. 11, alternatively of long and short radius, the opposite surface being provided with reflecting facets m<1>, m<2> at right-angles. One or more plano-convex or double convex lenses L<1>, L<2>, L<3> may be placed in contact with the optical element E and the film F, both in taking and in projection.

Title: Improvements in processes of producing tetra ethyl alkyl lead
IPC: C07F7/24
Filed: 1934-12-01
Abstract: In the preparation of lead tetra-alkyls by interaction of lead mono-sodium alloy with alkyl chloride, the alkyl chloride is first added in only small quantity so as to initiate the reaction, as indicated by a falling pressure and rising temperature, whereupon the remaining alkyl chloride is added as quickly as possible consistent with the avoidance of excessive development of heat. For the production of lead tetra-ethyl, an autoclave fitted with water jackets and stirring mechanism is charged with the alloy and after warming to 35--50 DEG  C., a small amount of ethyl chloride is added. When the pressure falls with rising temperature, the bulk of the ethyl chloride is gradually added while cooling the autoclave.  The reaction is completed, after all ethyl chloride has been added, by warming the autoclave again.  The addition of the bulk of the ethyl chloride may, if desired, be interrupted when about half has been added, the remainder being added after a period of cooling.  In the same way lead tetra-methyl and lead tetra-propyl may be prepared. Reference has been directed by the Comptroller to Specification 214,221, [Class 2 (iii)].

Patent GB-834771-A (GB)
Title: Improvements relating to the production of glycerol and glycols
Filed: 1958-10-30
Abstract: Glycerol and glycols are obtained from sugar alcohols by cracking and catalytic hydrogenation of a sugar in aqueous alkaline solution, the process being carried out at a temperature in the range 200-300 DEG C. and a hydrogen pressure of 500-1000 atm. in a solution having a pH of 8-10.  The pH of the solution may be adjusted by the addition of calcium hydroxide. The preferred catalyst is nickel on a carrier, for example, pumice or kieselguhr.  If a temperature higher than 250 DEG C. is required it may be produced by introducing oxygen under pressure into the reaction vessel to burn some of the hydrogen.  The introduction of oxygen under pressure also reduces the resinification of the catalyst.  Wood sugar alcohols obtained by the hydrogenation of wood sugars may be used as starting materials.  In an example, sorbitol is cracked and catalytically hydrogenated to give glycerol and glycols along with a small amount of erythritol which may be submitted again to the process.
