Abstract: 703,832. Photo-electric control systems. GALL, D. C. Dec. 14, 1948 [Nov. 14, 1947], No. 30310/47. Class 40 (3). [Also in Group XXXVI] In an automatic control system for calibrating A.C. instruments (see Group XXXVI) the current flowing in the coil 45 of a dynamometer 44 is controlled by a current regulator 46 in accordance with the illumination of a photo-cell system 47. The dynamometer 44 carries a mirror which reflects light from a source 48 on to two pairs of photo cells, Fig. 2 (not shown) arranged on either side of the zero position of the reflected beam. Slight unbalances cause either one of the inner pair of photo cells to operate the regulator 46. If due to a fault the unbalance condition becomes too great to be handled by the regulator 46, the beam moves on to the second photo-cell on the appropriate side of the zero position and this cell operates either to switch off the regulator or to lock it in its maximum correction condition and energize an alarm.

IPC: D01H1/30
Filed: 1956-10-08
Abstract: 804,567. Spinning and twisting machines. PELLIZZARI & FIGLI S.p.A., A. Oct. 8, 1956 [Oct. 11, 1955], No. 30611/56. Class 120(2) [Also in Group XXXVII] In a system for varying the spindle speed of a ring spinning frame according to a pre-arranged programme, also cyclically varying it with the guiding eye movement, the motor 21, Fig. 3, is supplied by an A.C.-D.C. converter such as a Ward Leonard Set 50, 51, the motor field windinig being separately excited from a rectifier 54 and constant voltage transformer 53. The generator field winding is connected to rectifier 62 and magnetic amplifier feedback winding 63. The A.C. windings of the amplifier 58, 59 complete the rectifier circuit from transformer 60, 61. The control Winding 64 is supplied from series connected resistors 65-67 each connected to a potentiometer 77-79 supplied over rectifiers 74-76 from transformer windings 71-73 respectively. The initial speed is set by slider 80, this being increased by further potentiometer sliders 84, 85 mechanically coupled to shaft 94, Fig. 1, which is rotated gradually by a ratchet and pawl mechanism from cam 30 by arm 28. The maximum speed is determined by the settings of potentiometers 77-79 in series. As arm 28 oscillates, an armature 91 linked to it varies the impedance of coil 90 connected in series with rectifier 76, hence as arm 28 is also connected to eye 16 through linkage 23-27 and cord 38, the motor speed is varied cyclically with the position of eye 16.

Title: Improvements in apparatus for use in television or like systems
IPC: H03K4/86
Filed: 1929-10-09
Abstract: 341,049. Producing oscillations by low-pressure discharge apparatus or commutator switching arrangements. ASSOCIATED TELEPHONE & TELEGRAPH CO., 1033, West Van Buren Street, Chicago, U.S.A. Oct. 9, 1929, No. 30676. Convention date, Nov. 9, 1928. [Class 38 (ii).] The potentials controlling the scanning action of a television cathode-ray receiver have their wave-form and frequency determined either by neon tube oscillators, or by the periodical discharge of condensers by a motor-driven interrupter. In an embodiment of the first system, potentials for the pairs of plates 5, 6 and 7, 8, in the tube A are derived from resistances 29, 30 in series with condensers 27, 28 and a common battery 31 and resistance 35. The condensers 27, 28 are shunted by neon tubes 25, 26 respectively and each system generates fluctuating potentials across the output circuit, of the form shown in Figs. 3 and 4, the constants of the circuits being so chosen as to give the required frequencies, one of which is a multiple of the other. The common resistance 35 tends to keep this relationship constant. The frequency of the oscillators may be independently varied by adjustment of condensers 27, 28 or simultaneously by adjustment of the battery 31. In a modification (Fig. 2 not shown) the neon tubes are replaced by rotating commutators on a common motordriven shaft, and the potentials from resistances 29, 30 are fed to the cathode-ray tube through condensers.
