Abstract: 932,731. Measuring braking torque. CLEVELAND PNEUMATIC INDUSTRIES Inc. Aug. 24, 1960, No. 29309/60. Class 40 (1). [Also in Group XXXIII] Means for applying a torque compensating for that due to brake actuation on an aircraft bogie-type undercarriage are shown in Fig. 2. Twin wheels 23, 24 are journalled on the ends of a beam 16 pivoted to the undercarriage leg 10 at 17. The outer non-rotary part of a brake located between the rear wheels is connected to the beam by a link 27 containing a differential transformer which produces an electrical signal representing the braking torque applied to wheels 24. The signal is fed over amplifier 38 to an electric motor 52 controlling an hydraulic valve assembly 39, which supplies fluid at a pressure which is a function of the input signal to motor 52, to a piston and cylinder type actuator 32, to apply a compensating torque to the beam. A second electrical signal representing the braking torque applied to the front wheels 23 may be added as an input to amplifier 38. The torque-sensing link 27 is shown in section in Fig. 3, and has an armature 107 secured to one end of the link, and coils 103, 104 and 106 at the other end of the link. Coil 104 is energized from an A.C. supply, and coils 103 and 106 are connected back-toback so that their resultant output is proportional to the stress in the link, and thus to the braking torque.

Abstract: 417,282. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Goldsmith, A. N. ; 25, East 86th Street, New York, and Goldsborough, T. R. ; 207, Westminster Avenue, Merchantville, New Jersey, both in U.S.A.) Oct. 23, 1933, No. 29327. Convention date, Nov. 1, 1932. [Class 40 (iii).] The foreground and background action of a composite television picture occur separately and at different points. The background 1 and foreground 3 are separately scanned by cathoderay tubes 5, 7 controlled in common by sawtooth generators 31, 33 described in Specifications 394,597 and 403,283. The foreground figures 24 contrast with a black or complementary black surround 26, and while signals corresponding to the figures are produced, a bias is applied through an amplifier 27 to a grid 29 in the tube 5 sufficient to block the tube. Thus no background signals are transmitted from parts corresponding to the positions of the foreground figures, and ghost effects are prevented. Alternatively the surround 26 is white and the effect of foreground signals on the tube 5 is reversed. Ghost effects may be produced by reducing the potential applied to the grid 29. The two sets of signals pass through separate amplifiers 17, 19 to a combining amplifier 25, a modulator 35 and a transmitter 39. The signals are also applied to a monitoring cathode-ray tube 36, and the pictures photographed by a cinematograph camera 38. Specification 392,456 also is referred to.

Filed: 1972-06-22
Abstract: 1366247 Counters KIENZLE APPARATE GmbH 22 June 1972 29361/72 Heading G4D In a counter in which the lowest denomination wheel, which is continuously driven, is marked with one hundred divisions, means is provided to separate the two halves of the wheel la, 1b and to drive each independently back to the last whole number value so that the counter shows an unambiguous reading with the figures in a straight line. The counter may be used for instance as the price readout dial of a petrol pump. When at the end of dispensing the nozzle is hung up it rotates a shaft 8 moving a driving arm 12 and, through spring connections 37, 39, further arms 9 and 11 against the number wheel assembly 1a, 1b. The arm 9 first engages teeth 2 on portion 1a to push it back to the last division mark. Arm 11 then engages teeth 4a on an intermediate member 4 turning it clockwise so that a pin 4c shifts a pivoted member 6 to release a bolt 20 and thus allow independent rotation of the two portions 1a, 1b. Finally the nose of arm 12 engages with one often cams 5 on portion 1b to restore it to the last whole number position; if the latter is a 9 it may also restore the higher denominations if transfer has already commenced. In a modification (Figs. 5-7, not shown) the portion la is formed with a series of step like cams which are sensed to cause a numbered sector to move in front of the graduated scale to display those figures which are not printed on it giving an entirely numerical reading. When the shaft 8 is restored, springs drive the number wheels back to their original positions. The arrangement can therefore be used to allow read out, either visual or electrical, of any continuously moving counter.
