Abstract: 403,744. Turnstiles. BAILEY, A. J., and BAILEY, F. M., Albion Works, Salford, Manchester. July 5, 1932, No. 18959. [Class 106 (iii).] The turnstile pillar 8 carrying the arms 10 has fixed to it a plate 11, Figs. 1 and 2, with rollers at its corners to bear against the T-head 14 of a ram 13 which is urged towards the plate by a spring 15. The inner end of the ram is connected to a lever 16 carrying a coin-pocket 19 normally prevented from more than a slight movement by spring catches 21. When two coins are inserted, pressure on the arms 10 moves the ram 13, the catches being lifted by the coins to permit a full stroke of the ram. In a modification, Fig. 4, showing the application to a cage turnstile allowing free exit, the arms 10 are carried by a central square pillar 8 which passes through a box 29 having an extended cover 30 to form a bracket for a box 31 containing the coin-freeing mechanism for controlling the movement of a spring-pressed ram 14. This ram has an adjustable coupling 41 and coacts with rollers on a square plate 11 revoluble on the cylindrical bush 32a of a second square plate 32 which is fixed to the pillar 8 and has rollers coacting with a spring- controlled ram 38. The plate 11 has cam teeth 37 projecting upwardly and engaged by corresponding teeth on a sleeve 35 which is slidable on the bush 32a but is held against rotation thereon by a key pin 36. The cam sleeve 35 is normally held in engagement with the teeth 37 by a spring 34 so that, when the arms 10 are turned to allow entrance through the turnstile after prepayment, the plate 11 is rotated by the sleeve 35 and moves the coin-freed ram 14. During exit, the plate 11 is held stationary by the ram 14, and the cam sleeve 35 slides up the bush 32a compressing the spring 34.

Title: A vehicle pneumatic-mechanical suspension system comprising air springs and a device for controlling the pressure in said air springs
IPC: B60G17/052
Filed: 1961-05-26
Abstract: 939,388. Road vehicle air suspension systems. FABBRICA ITALIANA MAGNETI MARELLI S.p.A. May 26, 1961 [May 28, 1960], No. 19142/61. Class 108(2). A device for controlling the pressure in air springs of a vehicle pneumatic-mechanical suspension system, has the air springs connected to atmosphere whenever levelling devices are inactive and the pressure in the springs is substantially equal to that of the atmosphere. Air springs 1 controlled by levellers 3 and distributer 7, are connected by pipes 13 to valves 11 each having a piston 14 subjected to air spring pressure and a venting valve 17 controlled by a piston 18 from a distributer 22. The control circuit of distributer 7 has a manual switch 10 and an automatic switch 9 (controlled e.g. by the vehicle speed) which are linked with switches 23, 24 in the circuit of distributer 22. With the vehicle travelling loaded, switches 9 and 10 are open, and distributer 7 and levellers 3 are inactive. Switch 25 is held open by piston 14 so distributer 22 is inactive and chamber 19 of valve 11 is vented and valve 17 closed. On stopping and unloading, switch 9 closes to energize distributer 7 to supply compressed air to levellers 3. When the vehicle is empty the springs are at atmospheric pressure and piston 14 is moved by spring 15 to close switch 25; however switch 23 is held open and valve 17 remains closed. On movement of an empty vehicle, switch 9 opens and switch 23 closes to energize distributer 22 to pressurise chamber 19 to open valve 17; the springs are therefore connected to atmosphere via orifices 16 so preventing high pressure build-up in the springs 1 due to vibrations of the vehicle. On loading a stationary vehicle, switch 23 is open and switch 9 closed, cylinder 19 is vented and valve 17 closed with the levellers 3 activated to adjust the air spring pressure accordingly. Manual switch 10 is used to readjust the pressure in the springs when a load is displaced during travel.

Abstract: 231,074. Underwood, W. J., (Anthracite Separator Co.). Aug. 13, 1924. Density separators.-A spiral separator for coal or the like has a runway composed of perforated plates, through which fluid is discharged to assist in the separation of materials travelling on the runway. A hollow column 10 with ports 32 carries brackets 12 to support the runway 14. This consists of a perforated floor 16 above an imperforate floor 18, the space between the edges being closed by a spiral bar 22. The spiral chamber 20 thus formed is in communication with the interior of the column 10 through the ports 32. Various forms of perforated plates are described. In the form shown in Fig. 2, ports 36 are formed by stamping the metal to form crests 39 and indentations 40. In a modification, elongated tongues 42 are punched to stand away from the surface of the plate. These tongues may be pointed to form a triangular port. Air or other fluid is supplied through the tube 34 and is discharged along the surface of the runway through the openings 36; this action assists centrifugal force on the particles travelling along the runway. The material which passes over the edge is caught by a conveyer thread 60. The fluid supply can be controlled by varying the speed of the blowing engine or by means of the valve 33. To increase friction on the runway surface, the plates can be assembled with the port projections extending upwards. The inclined shoot 48 is constructed with perforated plates in the same manner as the runway.
