Abstract: 1,126,416. Knitting-machines. WIRKMASCHINENBAU KARL-MARX-STADT. VEB. 31 March, 1966, No. 14352/66. Heading D1C. A pivoted latch detector 3 which when deflected by a latch interrupts the the control circuit of the machine has a magnet 6 secured to its remote end which when the detector is in its operative position is held by the magnetic influence against a switch 7. Movement of the detector by the latch causes the magnetic influence to decrease as the magnet moves away from the switch such that the force exerted on the latch when the detector bears on the tip is at a minimum, and distortion of the latch is avoided. A light spring 8 ensures the return of the detector to its operative position and its loading is only sufficient to overcome the frictional resistance of the pivot for the detector. A latch opener 18 is associated with the detector and is coupled thereto by a toggle mechanism to ensure that during initial starting up on base needles the latch opener is operative and the detector inoperative. In an alternative arrangement the magnet may influence the detector towards an inoperative position in which it actuates the switch.

Title: Improvements in or relating to brake operating mechanisms
IPC: F16D65/28
Filed: 1938-05-13
Abstract: 497,914. Brakes; electric motors. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. May 13, 1938, No. 14388. Addition to 495,897. [Class 103 (i)] [Also in Group XXXV] An auxiliary brake for stopping a centrifugal device which, as described in the parent Specification, is used to release a spring- or weight-applied main brake, is arranged to be released before the centrifugal device has completely stopped. The auxiliary brake is released by the axial pull between the stator and rotor of the driving motor of the centrifugal device and to increase this pull the rotor is of conical form. The auxiliary brake disc 3 secured to the motor shaft 13 is splined at 32 to the shaft 4 of the centrifugal device 52 the links of which are pivoted at 41 to the shaft 4 and at 61 to the slidable member 6 to which is attached the applying weight of the main brake. The rotor and stator 11, 12 of the motor are of conical form as shown. A spring 43 is disposed between the shaft 13 and a rod 44 slidable in a bore in the shaft 4 and resting by means of a transverse pin 45 upon cam surfaces 521 formed on the links 52. In the runing position of the parts as shown the axial pull on the rotor 11 raises this and the disc 3. When the motor circuit is broken, the rotor falls assisted by a spring 7 and the disc 3 is applied to a stationary part 21, this action being cushioned by the spring 43 but when the speed of the device has fallen to a certain value, the rod 44 is lifted by the cam surfaces 521 and the brake disc is thus disengaged. The applying weight of the main brake thus falls at first quickly and then slowly to give a gradual application.

Title: Improvements in and relating to television systems and thermionic valve circuits for use therein
IPC: H03C1/22
Filed: 1938-05-14
Abstract: 518,210. Valve modulating circuits ; television. I.M.E. SYNDICATE, Ltd., and NAGY, P. May 14, 1938, No. 14460. [Classes 40 (iii) and 40 (v)] In a television system employing a light modulating cell consisting of a fluid vibrated at supersonic frequency by an oscillation modulated with the video signals, the modulated oscillation is fed to the cell from a mixing valve. The mixing valve is fed with high frequency oscillations and its bias is varied in accordance with the video signal by direct coupling to the load impedance of a further valve. The valve V1 operates in a Colpitt's circuit to generate the supersonic frequency which is fed over condenser C7 to the grid of the mixing valve V3. The video amplifier V2 has a load resistance R4 and choke RFC2 in its anode circuit, but is decoupled for radio frequencies by condenser C8. The grid of the mixing valve is connected directly to a variable tapping on the load R4 which determines the amplitude of the video signals fed to valve V3 and also the direct current voltage between cathode and grid of V3. The modulated high frequency is obtained from the anode circuit of the mixing valve consisting of the band pass filter formed by tuned transformer T1. With suitable choice of peak oscillator voltage, in relation to the video signal voltage and mixer grid bias, a modulation characteristic is obtained which corrects for the voltage-light modulation characteristic of a cell of the crystal type.

Filed: 1944-08-01
Abstract: 593,687. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Aug. 1, 1944, No. 14671. Convention date, Aug. 28, 1943. [Class 40 (iv)] In a multi-potential marking system of the kind described in Specification 592,846, the break-down of the gas-filled tube in the test set directly alters the potential of the test terminal to prevent double connections. It is also arranged for the test to be repeated so that delay and wrong connection are avoided if the switch stops between terminals or on a terminal beyond that on which it found the stopping potential. On the seizure of the switch shown, BR completes a test circuit from wiper T to the thermionic testing pair V1, V2 and AR (provided the appropriate digit has been registered and RSR, RSR2 are energized) completes a driving circuit for the power magnet. When the potential found by the switch corresponds to that selected by the register RB, the cold cathode tube GV fires and energizes GVR to stop the switch and RSR falls, disconnecting RSR2 which, however, does not fall immediately. At the same time. the change in potential of the test circuit over the b-wire due to the discharge makes the seized circuit non-selectable. Shortly afterwarde, the energization of GSR releases GVR and energizes GRR which keeps RSR disconnected. In the selector, AR is released at the same time as the power magnet to disconnect the b-wire from the T-wiper but in the seized selector (not shown) the operation of relay BR transfers the characteristic test potential of the B-terminal from the T-terminal. GV thus fires again and causes the advance of the sequence switch. If GV fails to fire before the relapse of RSR2, GRR falls, RSR reoperates and the selector is re-started. Specification 577,088 also is referred to.
