Abstract: 956,734. Lathes and milling &c. FABRIQUE DE MACHINES MIKRON S.A. May 4, 1962 [May 24, 1961], No. 17330/62. Headings B3B and B3K. An hydraulic feeder and positioning device comprises an oscillating member 2 mounted together with an actuating mechanism on a machine frame 1, the frame incorporating a workpiece charger 3 and a quadrant shaped housing 6 within which the member 2 is pivotally disposed about an axis 8. The oscillating member 2 has a fixed catch member in the form of a housing 11 with a flexible side blade 10 which receives workpieces 4, and a radially displaceable catch member comprising a piston and cylinder assembly the rod of which is provided at its free end with a U-shaped clamp 15 one of the side arms of which is flexible. The actuating mechanism for the member 2 is a piston and cylinder assembly 21 and 20 respectively the piston is biased by a spring 26 to effect the return of the member 2 to its initial rest position. The band 27 of a conveyer carries discharged workpieces after machining, the conveyer being successively is displaced in conjunction with the piston 21 and the oscillating member 2 by way of quadrant 24 lever 23 and pusher and rocket wheel 29 and 28 respectively. The operation of the hydraulic devices for both the member 2 and displaceable catcher is effected by valves of known type connected externally. When the oscillating member 2 is at rest in the position shown with a workpiece 4 in the housing 11 of the fixed catcher member, the opening of an external hydraulic valve moves the piston 12 with rod 14 forward and the clamp 15 locates on the machined workpiece 17 which is automatically released from the machine. The hydraulic valve closes and the piston returns under spring pressure to its rest position carrying the workpiece. A valve supplies pressure fluid to the cylinder 20 displacing the piston 21 which rotates the oscillating member 2 through approximately 90 degrees by means of the lever 23 and quadrant 24 which places the fresh workpiece 4 in the machining position and at the same time moves the finished workpiece 17 in the clamp 15 to a position above the conveyer band 27 on to which it is released, movement of the conveyer band being simultaneously effected by the mechanical linkage 23, 28, 29. The pressure to cylinder 20 is then released and the piston returns to its starting position simultaneously effecting the return movement of the oscillating member in readiness for a repeat sequence of operation.

Title: Improvements in or relating to a method of making sponge rubber
IPC: C08J9/30
Filed: 1937-06-25
Abstract: A method of making sponge rubber comprises converting a latex composition into a foam by liberating carbon dioxide from a carbonate in the composition while preventing substantial coagulation, and thereafter coagulating the latex.  The carbon dioxide may be generated by reducing, as by the addition of an acidic material, the pH of the latex composition containing a carbonate and a stabilizer against coagulation on the reduction of the pH. Or the carbon dioxene may be generated by the action of formaldehyde on an ammonium carbonate or bicarbonate in the presence of a stabilizer.  The stabilizer may be one which acts at room temperature but not at high temperatures, or is only a temporary stabilizer at room temperature on the reduction of the pH.  The latex composition may contain a heat sensitizing agent, and the latex foam is preferably coagulated by applying heat.  In an example, an acid is mixed with a concentrated latex composition containing ammonium bicarbonate in the presence of a stabilizer against coagulation by acid, and magnesium carbonate as a heat-sensitizing agent.  The foam produced by the reaction is introduced into moulds and is then heated to cause coagulation. The stabilizer used is Emulphor O which is presumed to be made by the reaction of ethylene oxide and a higher alcohol.  The acid used comprises an aqueous solution of acetic acid, ammonium acetate and Emulphor O.  Other examples are given.

Abstract: 877,018. Gas liquid contact apparatus. STAGE, H. May 25, 1959 [July 28, 1958], No. 17782/59. Class 55 (2). A column for gas-liquid contacting comprises an exchange chamber formed of a base column plate 2 and boundary walls, a pipe inlet 7a and a pipe outlet associated with a tubular guide cover having upper and lower apertured ends. Preferably the base plate is disc-shaped and the boundary wall is substantially perpendicular to the base plate. The pipe inlet and outlet may be disposed vertically and the base column plate horizontally. The upper apertured end of the guide cover may terminate in a straight or curved tube. As shown in Fig. 1, gas may flow through a bubble cap 3 in the direction of arrow F 1  into liquid 5. Liquid may flow through pipe inlet 7a on to the base column plate 2. The outlet pipe 7 preferably consists of a pipe section which passes through the base column plate 2 and is covered by tubular guide cover 8, the lower apertured end of which projects into the liquid. The liquid may enter through the opening 9 along the arrow F 2  under cover 8 and passes through inlet opening E into the pipe outlet 7. The gas to be contacted with liquid passes through the liquid and rises upwardly in a substantially non- turbulent manner through cover 8 to escape through upper apertured end 11. In a modification (not shown), outlet pipe 7 does not extend above the column plate 2 and the upper apertured end of the guide cover projects above the level of liquid supported by the base plate such that gas collecting beneath the cover discharges into free air space within the column. In Figs. 6 and 7 (a constructional form for smaller column plates 2) the gas supply is not effected through a centrally arranged bubble cap 3, but through a depending bubble cap 3 in the form of a dipping jacket extending along the edge of the column wall.

Title: Improvements in electrical detectors for detecting the passage of vehicles or like moving bodies
IPC: B61L29/28
Filed: 1937-06-29
Abstract: 497,495. Signalling the passage of a vehicle moving in a given direction. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and MOTT, J. E. June 29, 1937, No. 18066. [Class 105] A moving vehicle such as a train approaching a level crossing operates sequential contacts in an electric interlocking arrangement which is energized from a signalling circuit having a normally-closed contact opened by the vehicle and the interlocking arrangement is such that if the vehicle is moving in one direction (away from the crossing) a contact is closed in parallel to the contact opened by the vehicle and thus the signalling circuit is unaffected. Only a single line circuit and a single source are required. The sequential contacts A1, A2 and the normally-closed contact A3 may be provided by the vehicle-actuated contact device described in Specification 360,768. In the normal state the signalling circuit is energized by current from +ve., through a signal relay S. line L, a resistance RA, and the contact A3 to -ve. If a passing train first closes the contact A2 and then the contact A1 a relay AR is picked up and stuck by its contact AR1 until the contact A1 again opens; the pick-up energy is obtained from the voltage drop across the resistance RA while the stick circuit of the relay AR derives its energy from being in series in the line L. Thus it will be seen that current flow in the line L is not interrupted. If however, the train first closes contact A1 the relay AR is not picked up at such time and the stick contact AR1 is therefore open and since the contact A3 is also open it will be seen that current flow in the line L ceases with the result that the signal relay S drops. This brings the level crossing signal into operation by the open contact S1 dropping a stick relay D. The relay S is re-energized as soon as contact A2 is closed and continues energized over contact A3 when the train has completely passed. The level crossing signal remains in operation until the stick relay D is picked up by a treadle RA1 just beyond the crossing.
