Abstract: 737,044. Annealing metal strand. SYNCRO MACHINE CO. July 6, 1953 [Aug. 30, 1952], No. 18724/53. Class 72. Metal strand, i.e. wire or strip, is continuously annealed by being heated electrically in two stages, the metral strand in the second stage being in part in a liquid bath, and then being quenched in two stages to cool the strand to room temperature. As shown, the strand is fed from a coil 11 to a pulley 13 connected to an electrically neutral point, over adjustable pulleys 14-16, to a pulley 17 connected to a source of electric power, and through a pipe 18 containing a liquid, e.g. water, to a pulley 19 connected to an electrically neutral point. The metal strand is then cooled in a quenching device 20 by a counter current flow of water and dried by an air blast in a drier 22. It may then be coiled at 24. The strand may leave the quenching device with sufficient residual heat to be self-drying. A thin film of steam or water on the strand between the exit from the pipe 18 and the entrance to the quenching device 20 is stated to prevent oxidation of the strand.

Abstract: 1305497 Lifts; control of winding apparatus CLARK EQUIPMENT CO 3 June 1971 [15 June 1970] 18735/71 Headings B8B and B8L [Also in Division F2] An overspeed brake mechanism on a stacker vehicle elevator car 10 movable within frames 12, 14 comprises a generator 18 for providing a speed reference signal of the car, brakes 24, 26 on the car 10 for interacting with the frames and brake actuating means having a pyrotechnic charge electrically detonatable when the speed reference signal exceeds a particular value. Each brake comprises a pair of shoes 32, 34 pivotally mounted on the car and having cam surfaces 48, 58 engageable by a portion 74 of a slide bar 62, which when displaced downwardly due to said detonation causes the shoes to rotate such that serrations 46, 56 thereon engage the frame. A stop 76 on the slide bar 62 maintains the shoes in the disengaged position when the bar 62 is in its inoperative upper position. The slide bar 62 is secured to the wall of a piston spring biased into a brake inoperative position and movable into a brake operative position by the explosive force of a pair of pyrotechnic charges. The bar 62 also operates a switch to de-energize the elevator motion as it moves into its brake operative position. The generator 18 mounted on the car 10 has its rotor 20 drivable by a rack 22 on the frame 12 and a D.C. voltage proportional to the car speed and of polarity according to the direction of car movement, is generated with car movement. The electrical circuitry includes two unidirectionally conductive devices, which allow current flow from the generator to cause de-energization of the elevator rotor upon overspeed of the car 10 in the upward direction and to cause detonation of the pyrotechnic charges upon overspeed of the car 10 in the downward direction.

Title: Improvements in or relating to the control of washing or dyeing machines
IPC: D06B23/00
Filed: 1936-07-07
Abstract: <PICT:0473161/IV/1> The clothes receptacle of a rotary washing or dyeing machine is stopped in a predetermined position by the application of a brake operated by a piston and cylinder mechanism, the fluid supply to which is controlled by an electromagnetically operated valve. The circuit to the valve is prepared, after the closing (manually or from a timing drum) of contacts 8, through a control element C and is finally completed by closure of a switch 19, 20 actuated by the movement of the receptacle itself.  The element C includes a shaft 1 driven by a pilot motor and carrying two conductor segments 2, 3 of different sizes which coact with stationary brushes 9, 10.  On closing the contacts 8, a circuit is completed through contacts 6, 4; 3, 10; line 15 and relay 16.  Contacts 13, 14 close to maintain a circuit for the relay 16 through contacts 6, 4; 2, 9 and line 12 when the smaller segment 3 leaves the brush 10.  The closing of the contacts 13, 14 also prepares a circuit to the switch 19, 20, relay 23 and winding of the brake-operating valve V.  This circuit is completed by a striking pin 21 on the receptacle engaging the contacts 19, 20.  In the form shown in Fig. 1, the receptacle is rotated in alternately opposite directions by the reversal of its driving-motor which is effected through reversing contacts on the shaft 1, and the arrangement ensures that the circuit to the brake valve shall be completed and the brake applied only if the receptacle has not completed the major portion of its movement in one direction. A modification is described for use with machines wherein reversal is effected through a clutch or belt shifting device.  The valve V may be that described in Specifications 447,359 and 473,140, [Group XXIX].

Title: Improvements relating to generators of frequency modulated oscillations

Filed: 1943-11-13
Abstract: 569,327. Frequency modulation. COSSOR, Ltd., A. C., and DAVIE, O. H. Nov: 13, 1943, No. 18954. [Class 40 (v)] A frequency-modulated valve generator comprises a valve with one output electrode and a control grid associated with a resonant circuit to provide feed-back oscillations, the other output electrode being connected to a reactive impedance, and the signal voltage being applied in the control grid circuit to vary the grid damping. As shown in Fig. 1, the anode circuit of the pentode valve V1 is tuned by inductance coil L3 and variable condenser C2, and is back-coupled to a coil L2 in the control grid circuit. The screen circuit includes inductance coil L1, resistance R3 and variable condenser C4, all effectively in parallel, with resonance at a frequency much lower than the oscillation frequency. The leak resistance R2 of the control grid receives a mean positive voltage from the potential-divider R5, R6 ; and a varying voltage proportional to the signal from the source M amplified by the valve V2, is superposed on this positive bias. Frequency-modulated output is taken from the anode of the valve V1. The network L1, R3, C4 is selected or adjusted to give a constant frequency deviation throughout the tuning ranges of the oscillator, and the Specification states suitable dimensions for three such ranges. By omitting the coil L1, the frequency deviation may be made approximately proportional to the carrier frequency. In a modified circuit, Fig. 2, the grid leak of the valve V1 comprises a low resistance R8 in series with a control valve V3, the anode of which is given a low positive voltage by a source B. The microphone M2 is transformer coupled to the grid of the valve V3 and varies the resistance of that valve.

These bars are connected by vertical rods y, and are supported by weights z. One of the rods is adapted through the medium of springs 2, 3 to turn a crank 4 on a shaft 5. Other cranks on this shaft actuate the clutches. The valve covers are divided diametrically into two parts, one part containing suction valves d and the other part delivery valves e. Grain is drawn into the pump through the pipes f, and delivered through the pipes g. In a modification the piston receives the grain, and has a valve or valves through which it is delivered on the delivery stroke.
