Title: Conveyor systems
IPC: B65G19/02
Filed: 1952-07-08
Abstract: 744,297. Endless-chain conveyers. BURGH, A. R. DE. July 8, 1952, No. 17220/52. Class 78 (1). In a conveyer of the kind in which loadsupporting pallets 4 are propelled along parallel roller tracks 1, 2 by pushers 11 mounted on a horizontally and vertically flexible endless chain 5, means is provided for effecting close packing of the pallets along a portion of the track, e.g. that within an oven 23, by withdrawing the pushers from driving engagement. Withdrawal is effected by deflecting the chain 5 downwardly by guides 24, Fig. 2, from its normal plane of travel between the tracks. Upward guides 26 restore the chain to the driving position at the delivery end of the oven. Each pusher 11 is a U-shaped clip, Fig. 5, which engages a pin 12 depending from a pallet. The pallets may be packed side-by-side as at 28, Fig. 1, instead of end-to-end by providing a side guide 29a at a relatively sharp right-angled turn in the track. Friction members 30 in the form of spring clips are provided beyond the turn to ensure complete turning. The pallets are restored to the original position by a guide 32a. When the conveyer passes from a higher level to a lower one, Fig. 8, running away of the pallets from the pushers is prevented either by locking or braking the rollers 3 on the inclined section or by covering them by the horizontal flange 44, Fig. 9, of a channel-iron member 41. The rollers 3 at the receiving-end of the lower level are arranged more closely together to prevent the forward edge of a pallet coming into locking engagement with one of them. Such engagement may also be prevented by extending the flange 44 over these rollers or by disposing endless belts around a pair of spaced rollers, e.g. 3a and 3b. Pallets may be turned through a right angle at any point by covering the rollers at one side of the track by a flange 48, Fig. 10, and replacing the rollers at the other side by castor wheels 49. Spring clips 50 ensure the correct positioning of the pallets. Shunt sections 18, 19, 20 are provided for the temporary storage of a pallet. Each includes conveying track sections la, 2a parallel to the main track and short connecting sections 1b, 2b and 1c, 2c.

Abstract: 439,888. Theft and like alarms and preventive devices. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and KRAMER, J. B., Witton-Kramer Electric Tool & Hoist Works, Witton, Birmingham. June 11, 1934, No. 17269. [Class 118 (i)] [See also Groups X and XL] A device for preventing theft from a display device comprises a beam of radiant energy, for example an infra-red beam, transmitted in a zigzag path and adapted upon interruption of the beam to operate an alarm and to release a door and shutter so that it is moved into the preventive position, and in order to obviate attempts to use a substitute beam, the power received from the beam is made to vary at a particular frequency, and an electric frequency relay responsive only to that frequency is arranged to effect the closing of the shutter when the beam is interrupted. The variation of power may be effected by a fifty cycle alternating power supply energizing a heater producing the beam, or the beam may be periodically interrupted by a rotating apertured shutter. Again, the beam may be directed by a moving mirror which varies in a periodic manner the proportion of the beam falling on the sensitive device. The shutter arrangement for the display device may be that described in Specification 437,205, [Group X]. The shutter is biassed by springs to the preventive position, and is released by an electrically controlled latch. The shutter may be pivoted and of trough or other shape so that when rotated it covers the object to be protected.

Title: Improvements in or relating to revolution counters and revolution direction indicators particularly adapted for ships' propeller shafts
IPC: G06M1/04
Filed: 1921-06-29
Abstract: 169,429. McNab, A. Sept. 20, 1920, [Convention date]. Revolution-direction indicators; differential speed indicators. - An instrument for registering the revolutions per minute and the total revolutions irrespective of direction of each propeller shaft of a twinscrew vessel, and also for indicating the direction of revolution of each shaft, comprises a casing 3 with a dial 6 graduated in revolutions, total-revolution counters 25, 25', pointers 28, 28<1> movable over the dial to indicate tens of revolutions and also the directions, and hundreds-of-revolutions wheels 74, 74<1> driven from the pointer spindles. The mechanisms for the two propeller shafts are substantially identical. A shaft 7 driven from the starboard shaft drives a secondary shaft 12, Fig. 3, through a clutch 9, and the total counter 25 is driven from this shaft 12 through bevel gearing 15, 16, a crank 19 and connecting-rod 20, and an arcuate pawl 23 and ratchet 24. The other total counter 25<1> is similarly driven but the pawl shaft 26 is extended to the opposite end of the counter. The shaft 29 of one pointer 28 carries a loose worm wheel 34 driven by a worm 73 on a shaft 68 driven through wheels 68 from a wheel 48 loose on the shaft 12. This wheel 48 is connected to the shaft 12 when desired by a friction clutch 55 operated from a push-rod 60 extending through the casing and fitted with a knob 5. The inner end of the pushrod is provided with a double-bevelled head 61 engaged by a knife-edged spring detent 62. The worm-wheel' 34 drives the pointer shaft 29 through a friction clutch member 36, which is provided with a cam portion 87, Fig. 2, adapted to rock an arm 84 once in each revolution of the pointer and thereby oscillate an arcuate pawl 79 to advance the hundreds wheel 74. A similar arm 84<1> for the other hundreds wheel 74<1> is held by a weight 89 against a cam on a clutch member 47, Fig. 3, on the hollow shaft 31 of the second pointer 28<1>. The boss of the pointer 28 may be turned by means of an external knob 42, or may be moved along its shaft to bring a pin 44 on the pointer into engagement with a hole in the other pointer 28<1>, whereby both pointers may be reset to zero when the secondary clutches 55, 55<1> are opened. The hundreds wheels are zeroized manually through shafts 75, 75<1> extending through the casing. For measuring the revolutions per minute the secondary clutches are closed for a determined interval and the readings are taken from the hundreds wheels and pointers. The dial is suitably marked to indicate the direction of revolution, and the pointers are distinguished by colour or otherwise.

Abstract: 573,075. Valves. TOWLER, J. M., and TOWLER, F. H. Oct. 29, 1943, No. 17883. [Class 135] In a relief or reducing valve of the type in which the liquid to be controlled acts on the end of the valve plunger 5 to raise the latter to open position against its spring 17 or other load and in which the return movement of the plunger is damped by a piston 9, pressure liquid from the inlet 11 or outlet 12 can pass through a passage 13 in the piston to a space at the back of the latter and, during the lowering movement of the plunger 5, a needle valve 6 on the lower end of the latter closes the passage 13 so that the liquid in the space behind the piston can escape only slowly past the piston itself. In the raised position of the reducing valve shown, liquid can flow from the inlet 11 through a groove 20 in the casing and a groove 23 in the valve plunger, along an axial bore 25 in the plunger, and out through a groove 19 in the plunger to the outlet 12. A passage 28 leads from the inlet to the underside of the valve plunger so that, when the inlet pressure rises sufficiently, the valve will be lifted. A spring 15 tends to raise the damping piston into contact with the needle valve 6. In a relief valve, the inlet 11 and outlet 12 are in alignment and always in communication with each other, and lifting of the valve plunger opens a relief byepass. The valve plunger in this embodiment consists of a plain plunger, or of a plunger formed with a helical or vertical grooves, and carries an elongated needle valve 6 on its lower end.
