Title: Improvements in or relating to electric signalling systems
IPC: G08C19/02
Filed: 1931-01-05
Abstract: 364,834. Electric signalling systems. GENERAL ELECTRIC CO. Ltd., SMART, N. C., and CHUBB, A. A., of General Electric Co., Stoke, Coventry. Jan. 5, 1931, No. 337. [Class 40 (i).] In a system for repeating the movements of a member such as a n instrument pointer, the member varies the electrical condition of a circuit containing a glow discharge tube so as to vary the frequency of the relaxation oscillations of the circuit and thus operate a distant frequency respons i v e indicator. As shown in the Figure, a pointer P controls a variable resistance comprising a resistance member R immersed in conducting liquid L such as mercury, and adapted to be connected in circuit with a condenser C and a neon tube N. The circuit is supplied from a source of direct current and oscillations are produced, the frequency of oscillation being determined by the amount of resistance included in the circuit. The oscillatory current is transmitted through a transformer T which supplies the line wires LA, LB of a frequency responsive indicator F either directly or through carrier current modulating equipment. A condenser CS is provided to assist oscillation. The resistance element R may be formed of conducting ebonite and the discharge tube may .contain a small quantity of mercury vapour. In a modification, a fixed resistance may be employed in conjunction with a pondenser variable by the movable member. In a further modification, the member controls an arcuate resistance element having a number of inset metallic contacts which co-operate with a mercury bead contained in an adjustable chamber. In a further form, the movable member controls a contact arm which normally moves out of contact with a resistance element but may be depressed into engagement therewith when an indication is desired. The Provisional Specification states that the distant indicator mav be connected directly in series with the neon tube or in parallel with an impedance which is in series with the tube and may take the form of a direct current instrument operated by the charging current of a condenser which is charged and discharged by the received impulses.

Patent HK-22093-A (HK)
Title: Stepping motor assembly
Inventor: BESSON RENE
IPC: H02P8/02
Filed: 1993-03-11
Abstract: The purpose of the invention is the realization of a motor assembly formed from a stepping motor and its control circuit capable of operating at a maximum speed substantially greater than that obtainable with comparable existing assemblies. This is effected by substituting for the single coil or for each coil of a known motor two or more windings and adopting a control circuit which connects the windings in series or parallel according to whether motor drive pulses of low or high frequency are applied thereto. The total number of winding turns and the sum of the resistances of the windings are preferably chosen to be equal respectively to the number of turns and the resistance of the coil which they replace in order to avoid basic modification of the characteristics and performances of the motor when operating at low speed. When the windings are connected in parallel their resistance and equivalent self-inductance are less than that of a single coil. The energy transfer from the voltage source to the rotor of the motor is increased and facilitated and the maximum speed of the motor is considerably increased.

Title: Track control system for positioning a light beam
Inventor: FUELDNER FRIEDRICH
IPC: G11B7/09
Filed: 1996-02-29
Abstract: In a CD player, a light beam for reading the information is focused onto the CD disc. Serving for this purpose is an optical scanning system with a laser diode, a plurality of lenses and a photodetector (P), onto which the CD disc reflects the light beam. By means of a track control system, the optical scanning system is displaced in the radial direction with respect to the CD disc, so that the light beam is taken along the spiral data tracks. Until now, offset voltages of the photodetector (P) have been compensated by manual adjustment of a potentiometer. In order to replace the laborious manual adjustment by an automatic compensation of the offset voltage, with an open control loop a compensation voltage is superimposed on the output voltage of the photodetector (P) and varied until the sum of the output voltage and the compensation voltage assumes a predeterminable value. The control loop is then closed. The track control system is suitable for playback devices which reproduce information from optical recording media in disc form, for example CD players and video-disc players. <IMAGE>
