Title: Improvements in winding mechanisms for spring-driven clocks
IPC: G04B5/22
Filed: 1953-05-11
Abstract: 726,005. Clocks. GENERAL MOTORS CORPORATION. May 11, 1953 [May 21, 1952], No. 13011/53. Class 139. A winding mechanism for a spring-driven clock comprises a flexible diaphragm mounted in a chamber connectible to a source of repeated suction impulses, such as the intake manifold of an internal combustion engine, deformable in one direction by said impulses against a return spring, and connected to one arm of a bell crank pivoted about an axis substantially parallel to the plane of the diaphragm, the other arm of the bell crank being connected to a member which is pivoted about the axis, normal to the bell crank pivot, of a ratchet wheel connected to the winding spindle of the clock and which carries a pawl for engagement of the ratchet wheel to transmit return movements of the diaphragm to apply a winding force to the spindle. The source of suction impulses is connected to a coupling 42, Fig. 1, of a housing 36 containing a diaphragm 44 clamped at its periphery and carrying substantially flat discs 48, 50 on opposite sides. A rivet like member 52, fixed to the centre of the diaphragm, has an extension 70, Fig. 4, connected to one arm of a bell crank 62 pivoted on a bracket 60. The other arm 72 of the bell crank 62 engages an opening 76, Fig. 2, in one arm of a bell crank 74 pivoted on the winding spindle 28 of the barrel 24, Fig. 1. The other arm of the bell crank 74, Fig. 2, carries a pawl 78 spring-pressed into engagement with the teeth 31 of a ratchet 30 fixed to the spindle 28. The arrangement is such that as the diaphragm is returned to the left by a spring 58 the pawl 78 moves the ratchet 30 and its spindle 28 counter-clockwise to wind the mainspring. A pawl 80 prevents reverse rotation of the ratchet 30. The clock hands 6, 8, Fig. 1, are settable by a knob 16 with respect to the dial 10. The glass 12 is retained by a bezel 14.

Filed: 1937-05-07
Abstract: 490,086. Arc lamps. BUCKLEY, H. S. May 7, 1937, Nos. 13146 and 15474. [Class 39 (i)] One set of carbons in a multi-carbon are is brought into contact with the other by means of a trigger device which, when released, returns them by means of a lost motion device through a fixed distance normally less than that through which they were fed forward. For this purpose the trigger 6 engages a sliding rod 11 connected to the electrode holder 1 through a spring grip 17. The trigger moves the carbons 2, 2a into contact and when released, is returned by a spring 27, retracting the grip 17. The return movement of the electrode holder 1 is limited by a pivoted clutch plate 19 having an elongated hole so that the holder 1 can pass freely through it forwards, but is held on its return when the plate reaches the position shown by the dotted lines, the grip 17 sliding on the holder for the remainder of its motion. A screw 29 regulates the length of this return motion. In a modification, the sliding grip and clutch are applied to the rod 11, which is rigidly connected to the electrodes. The several pairs of electrodes are arranged in different vertical planes.

[Class 34(i)] Cloth is dried in contact with a heated drum, hot air also being blown on to the cloth from nozzles arranged concentrically around the exterior of the drum. As shown, a steam-heated drum 1 is surrounded by an insulating casing 6 forming a frame and into which the cloth 7 enters by a slit, contacts the heated drum and leaves by another slit, 9, 10, 11, 12 being guide rollers and 13 a folding device. Concentrically grouped about the drum are nozzles 14 which may be telescopic, and each of which acts in the widthwise direction of the cloth 7, the orifices opening near the face of the cloth. Air heated by a heater 16 is supplied to the nozzles by a fan 15. In a modification the periphery of the drum 1 is perforated and the fans 15 produce a vacuum in the drum by means of a suction manifold surrounding the shaft of the drum, the air thus sucked in being driven into the nozzles 14. The heating of the drum is in this case performed by the hot air passing through it and the width of the suction effect can be adjusted by the movement of plates inside the drum and fixed on screwthreaded rods.

Abstract: 1,115,096. Colour television. HAZELTINE CORPORATION. 28 March, 1966 [20 May, 1965], No. 13544/66. Headings H3W and H4F. A reflex amplifier 10 translates a chrominance carrier signal from input terminal 11 to output terminal 28, and thence to synchronous demodulator 32 to derive R-Y and B-Y colour-difference signals, and also translates the colour-difference signal -K(G-Y), which is derived in matrix 36, from input terminal 12 to output terminal 32. Anode circuit 20 is tuned to the carrier frequency, whilst a circuit 29, 30 series resonant at the carrier frequency shunts the anode load 23 for the G-Y signal and a further similar resonant circuit 16, 17 shunts the input resistor 15 across which the -K(G-Y) signal is mainly developed. In a modified arrangement, Fig. 2 (not shown), provision is made to apply a " colour killer " signal to the grid circuit of valve 13, so as to disable the amplifier during reception of black-and-white signals. Reference is made (without giving details) to alternative arrangements in which (1) amplifying element 13 is replaced by a pentode valve or transistor; (2) one or both of the signal components are translated without phase inversion; and (3) the colour difference signal is other than G-Y.
