Abstract: 554,910. Knitting-machines. HOLMES, H. H., HURD, J. C. H., and WILDT & CO., Ltd., May 8, 1942, No, 6264. Addition tc 506,837. [Class 74 (ii)] The latch-opening devices of the parent Specification are arranged to yield or be displaced to allow the needle hooks to pass behind them so that damage or undue wear of the needles or latch-openers is avoided. The latchopening devices may be provided upon the sinkers or upon sinker-like members, either arranged in the same tricks as the sinkers or in separate tricks. In a machine employing inside sinkers 6 provided with latch-opening projections 8, a movable cam part 17 is aranged to protrude from the top sinker cam ring 11 into the cam track at the latch-opening position and is yieldable against the pressure of a spring 21 to allow the corresponding sinker to move outwards slightly when the projection is engaged by the hook. The spring 21 can be adjusted by a screw 20. Alternatively, the sinkers are moved in futher than is necessary for latch-opening and the appropriate part of the sinker cam is recessed so that the sinker can be moved outwardly by the needle hook. Specifications 15008/00, [Class 74], 24290/12, [Class 74 (ii)], and 391,212 are referred to.

Abstract: 1,180,415. Coin-freed apparatus. JOHN R. LEBB DISTRIBUTORS Inc. 10 Feb., 1967 [27 Oct., 1966], No. 6439/67. Heading G4V. A coin-freed vending apparatus comprises a bar 39 from which carrier bags 21 or the like are suspended, a pivoted gate 54 engaging a slot 40 in the bar, stops 70, 71A limiting movement of the gate to prevent the gate disengaging the slot, and a coin controlled mechanism for withdrawing the stop 71A and releasing the gate. The handles of the leading bag are received in a recess 67 in the gate and the gate pivoted counterclockwise to release the bag, the rear edge of the gate preventing removal of the succeeding bag. The stop 71A is withdrawn against spring pressure by a solenoid 71 when a coin switch 75 is closed. In addition, a hold-on relay 79 is energized to close contacts 79B. The gate carries a mercury switch 80 in the supply line to solenoid 71 and relay 79 whereby the solenoid and relay are de-energized when the gate is pivoted to the release position. A switch 81 may be operated by an official to open the gate for loading. A thermal cut-out 82 operates if the gate is not pivoted within a predetermined time. A counter 83 is stepped on each actuation of the gate. In a modification, the stop 70 is omitted and the gate shaped to contact the stop 71A on two sides, Fig. 10 (not shown). The electric circuit may be modified by omitting switch 81 and providing the mercury switch with two pairs of contacts. When the gate is pivoted to the release position the solenoid 71 is de-energized as before to release the stop 71A. If the gate is moved further counterclockwise the stop 71A latches the gate in this new position for loading as shown in dot-dash lines, Fig. 4, and the second pair of contacts close to prepare the circuit for the next coin. After reloading the apparatus, a second coin is inserted by an official to operate solenoid 71 and withdraw the stop 71A whereby the gate is returned to its initial position by springs 68, 69.

Abstract: 340,447. Plug cocks. MORRIS, G. R., (trading as MIDLAND BRASS FITTINGS CO.), 181, Aston Road, Birmingham. Feb. 28, 1930, No. 6608. [Class 135.] A plug cock having a vertical plug is operated by a lever handle c pivoted to the upper end of the plug and having a depending stop lug e, and an extended handle, disposed on opposite sides of the pivot. In the closed position, the plug is locked by the dropping of the handle c by gravity into a position in which both the extended handle and the lug e engage upstanding stops f on the cock casing. The plug is released by raising the handle to disengage one, of the stops, as shown. The stops f are conveniently formed by a raised arcuate shoulder of the casing extending part way round the plug. Since the lug e of the handle always lies below the level of the arcuate shoulder, these co-operate to act as limit stops for the movements of the plug.

Title: Improvements in or relating to radio receiving circuits
IPC: H03G3/26
Filed: 1952-03-17
Abstract: 709,975. Radio receiving circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 17, 1952 [March 20, 1951], No. 6832/52. Class 40 (5). [Also in Group XXXVI] An arrangement for muting the output of a radio receiver when it is not accurately in tune with the received signal comprises three tuned circuits 3, 4 and 5 tuned to the signal frequency (e.g. the intermediate frequency) and coupled together as shown so that a progressive phase-shift of 90 degrees occurs between the circuits when the incoming signal is correctly tuned, the circuit 3 being so connected in series with the circuit 5 that the signals developed across the two circuits are in antiphase at tuning and are of the same amplitude whereby a zero output is developed by the rectifier circuit 9, 10. When the incoming signal is not accurately tuned, the output from rectifier circuit 9, 10 assumes a negative value and is applied through a filter circuit comprising resistors 11 and condenser 11<SP>1</SP> to the control grid of amplifying valve 13 to which the output of second detector 6 is also applied, to bias the valve beyond cut-off. Automatic gain-control is provided in a conventional manner by a detector circuit connected to the circuit 3. In a modification, Fig. 2 (not shown), the circuit is connected through the condenser 15 to a tapping point (e.g. the mid-point) of the inductance of circuit 5. The end of the tuned circuit not connected to the rectifier circuit is connected to earth through a parallel-connected resistance capacity network matched to the rectifier circuit. In a similar arrangement, Fig. 3 (not shown), both ends of the circuit 5 are connected to rectifier circuits, the muting voltage being taken from across the two rectifiers in series. In this arrangement also, the connection between circuits 3 and 5 is taken from a tapping point on the circuit 3.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/48
Filed: 1951-03-22
Abstract: 690,305. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd., and SIMMONS, A. W. Jan. 1, 1952 [March 22, 1951], No. 6865/51. Class 103 (i). In a distributer valve for fluid pressure railway braking apparatus, the control chamber, indicated diagrammatically at 9, is charged, under brakes released conditions, by air from the auxiliary reservoir or brake pipe through a passage 6 and past a valve 7, held open by the lower part 3 of a piston 2, the piston being kept in its uppermost position by a biasing spring 34 and the pressure acting in chamber 4. An annular gasket 13 in the upper part 1 of the piston 2, by its engagement with an annular projecting rib 12 seals off the upper outlet of a restricted passage 10 through the piston. When the brakes are applied and the slide valve moves down, so as to allow air to pass to the brake cylinder 24 through port 37, passage 22, past valve 21 and by passage 23, the auxiliary reservoir is also connected direct to the chamber 11 above piston 1 by passage 26. The piston 2 is therefore moved down and valve 7 closed before any large reduction in auxiliary reservoir pressure occurs. When a certain pressure has been reached in the brake cylinder, the piston 14 of the quick inshot valve moves down thus allowing both valves 21 and 25 to close so that air passes to the brake cylinder only through restricted passage 29. On release of air from the brake cylinder through passages 23, 33, port 30, recess 31, port 32 and passage 33, the pressure will be maintained in the closed passages 26, 28, associated with the space above the piston 2, by flow of air through the restriction 10 so that the piston 14 of the quick-inshot valve will be kept in its lower position until the brake cylinder pressure has been almost fully released. When the piston 14 does rise under the action of spring 20 to open valves 21 and 25 pressure is rapidly exhausted from above piston 2 which rises under the action of spring 34 to open valve 7 and put the control chamber 9 and auxiliary reservoir into communication with one another. In a modification, shown in Fig. 2, an additional port 38 closed by a gasket 40 in the lower part 3 of the piston, when in its bottom position, may be connected to a quick service or accelerator bulb so that it will thus be vented only after the brakes have been released.

Abstract: 990,410. Friction clutches; controlling clutches. B. HIRANO. Feb. 22, 1962 [Feb. 27, 1961; Feb. 28, 1961; March 14, 1961; May 19, 1961 (2); July 7, 1961; Aug. 21, 1961; Aug. 24, 1961 (2)], No. 6980/62. Headings F2C and F2L. A friction clutch has a sleeve hub connected to the driven shaft by a screw connection tending to move the hub in the plate separating direction when rotated in the driving direction relative to the driven shaft, torque being resiliently transmitted from the sleeve hub to the driven shaft. The engine shaft 1 of a motor which carries a drive pinion 2 which is positively clutched to the shaft through dogs 37, 38 on energization of an electromagnet 40 through closure of switch S1 controlled by centrifugal means or throttle position to the engine speed responsive, or of switch S2 closed by engine starting means. The pinion 2, which may alternatively be directly connected to the shaft 1, drives a gear 4 to which are splined driving clutch plates 7. Driven plates 8 are splined to a hub sleeve 9 having a threaded connection 14 with a thrust screw 10 slidable on the driven shaft 3 and rotatably connected thereto by a pin 12 axially slidable in a slot 11. The hub sleeve 9 is resiliently connected to the driven shaft 3 by a torsion spring 16, the action of the spring and the threaded connection 14 being such that torque transmitted in the normal driving direction tends to disengage the clutch against the action of the spring. Clutch engaging pressure may be provided by axial load of the spring 16 and of a second spring 13 acting on the thrust screw 10. The screw 10 may be moved axially to disengage the clutch by a push-rod 17. In a modification, the pinion 2 may be coupled to the shaft 1 by balls moved radially by a plunger axially shifted by the electromagnet 40. In a second embodiment; Fig. 3, speedresponsive balls 20 carried by the driving gear 4 allow progressively greater engagement with increasing engine speed by moving the release datum of the thrust screw 10. This embodiment may be modified by mounting the centrifugal assembly externally of the clutch to act through the push-rod 17 or by similarly moving the push-rod or pin 12, through a screw-andnut mechanism acted on by a friction brake. In other embodiments the centrifugal balls may act between the driving gear 4 and the clutch plates 7 at chosen characteristic rates. In another modification, the push-rod 17 may be electromagnetically latched in the clutch disengaged position until the engine throttle is set to provide sufficient engine speed for acceleration from a standstill.
