Abstract: 1,211,441. Current stabilzers. RCA CORPORATION. March 29, 1968 [March 30, 1967], No.15319/68. Heading G3X. A load 13, e.g. the alignment coil of a television camera tube, is supplied with constant current from sources 16, 19 of opposite polarity by way of a circuit including series-connected complementary transistors 11, 12 inter-connected as shown with resistors 14, 15, 17, 18, 25 and diodes 21, 22, 23, 24, the load 13 being coupled to the junction 26 between the tranistors 11, 12; the resistors 15, 17 are variable, and their adjustable contacts are mechanically connected so that as one resistor increases in value the other decreases in like magnitude. Thus the magnitude and polarity of the current through the load 13 can be controlled by concurrently adjusting the resistors 15, 18, and this current, once established, tends to remain constant because the impedance of the current source at the point 26 is high since the current is derived from the collector electrodes of the transistors 11, 12; further, the current is stabilized against changes in in the sources 16, 19 by the inclusion of the Zener diodes 21, 24 in the base-emitter circuits of the transistors. The transistors may be of the insulated-gate field-effect type.

Title: Improved electric motor driven screw and nut mechanism
IPC: H02K7/06
Filed: 1946-05-24
Abstract: 612,462. Lifting-jacks. GENERAL MOTORS CORPORATION. May 24, 1946, No. 15755. Convention date, May 26, 1945. [Class 78 (iii)] In screw jacks driven by an electric motor through gearing, a locking member is provided which normally locks one of the transmission gears to prevent rotation of the screw, but is engageable with another of the transmission members to permit operation of the jack when the motor is energized. The speed reduction gearing between the motor 20, Fig. 1, and the screw shaft 70 comprises two ring gears 50 and 51, Figs. 1 and 3, and a cooperating hypocyclic gear 40, the latter being driven by the motor. One ring gear 51, attached to the screw shaft 70 by means of a torsion rod 61, is normally engaged and locked by the arm 128 of a pawl 115 which renders the gearing inoperative, but when the motor is energized an electromagnetic shifter rocks the pawl 115 so that the arm 128 disengages the ring 51, and the arm 127 engages the gear member 50 which is then locked against rotation and becomes a reaction member to effect drive. The electromagnetic shifter-comprises a solenoid 133, Figs. 1 and 2, which operates links 131 and 130 which rotate the rod 125 and pawl 115. The electrical circuit being such that the solenoid is energized at the same instant as the motor is connected in circuit. The non-rotatable nut 90, Fig. 4, has abutment lugs 84a and 85a at each end, each being adapted to engage one of the corresponding lugs 84 or 85, Figs. 1 and 4, on the screw shaft 70, so preventing its rotation when the nut is in either of its extreme positions, and as the gearing and screw are resiliently connected by the torsion rod 61, the jack is not harmed by the sudden engagement of co-operating lugs. Limit switches 111 and 110, Figs. 1 and 4, are controlled by the nut for rendering the motor and magnetic shifter inactive immediately before the nut moves one of its abutment lugs into engagement with a co-operating lug on the screw shaft.

Title: Improvements in or relating to frequency modulation radio receiver arrangements
IPC: H03D3/10
Filed: 1954-06-02
Abstract: 755,282. Frequency modulation receivers. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 2, 1954 [June 5, 1953; July 23, 1953], No. 16330/54. Class 40 (5). Relates to the reduction of pulse disturbances in frequency modulation receivers comprising a ratio detector having a resistance-capacitance filter for eliminating amplitude modulation. In one embodiment the I.F. signals are fed to ratio detector 2 ... 10, the demodulated output being applied through the filter 9, 10 to rectifiers 11, 12 connected in opposition. These rectifiers are normally maintained conductive by the P.D. developed across the amplitude modulation filter 6, 7 and applied through resistors 13, 14. When a sharp negative pulse reaches diode 11, diode 12 becomes non-conductive as the timeconstant of the output capacitor 15 in conjunction with resistor 14 is long compared with the duration of the steep-sided pulse component. Upon the occurrence of a sharp positive pluse the diode 11 is cut off. A further reduction of the disturbance may be obtained by applying to the capacitor 15 a phase-reversed version of the input pulse, Fig. 2 (not shown). Distortion due to varying D.C. currents flowing in the output circuit is avoided by employing a blocking capacitor between the resistor 9 and diode 11 and further resistors to complete the D.C. circuit of the latter, Fig. 3 (not shown).

Abstract: 355,231. Electrically-actuated valves. IGRANIC ELECTRIC CO., Ltd., 147, Queen. Victoria Street, London.-(Cutler- Hammer Manufacturing Co. ; Milwaukee, Wisconsin, U.S.A.) May 12, 1930, No. 16380/31. Divided on 354,813. [Class 135.] Driving mechanism for valves and other devices comprises a reversible electric or other motor 4, Fig. 2, a frictional slip clutch 7a, 7b, and speedreducing gear 5, 6, &c., having a lost-motion device, such as an epicyclic gearing with a wheel idle for part of an initial revolution until it reaches a stop, whereby the valve &c. is started from rest with a hammer-like blow. The motor is controlled by a pair of electromagnetic reversing switches under control of a dashpot-controlled timed relay, and limit switches'operated from the driven part. The motor 4 drives through a jaw coupling 8 and friction discs 7a, 7b held in engagement by a spring 28. Electromagnetic windings 30, 31 associated with the friction discs are also arranged in conjunction with automatic switch mechanism 66, 67, 68, Fig. 4, whereby increased frictional torque can be obtained at starting. For this purpose also the disc faces are undercut to provide an air gap 32, and a nonmagnetic shaft 26 is used. The stop for arresting the gear member of the planetary gear after its initial idle run comprises a. plunger which can be withdrawn by a hand-operated cam for operating the valve by hand. The limit switches, shown at 58, 59, are controlled by cams 55, 56 on a shaft 50, connected with the driven shaft through a second epicyclic reducing gearing, and operate the reversing switches through the timed relay. The switch mechanism 41, for supplying the energizing current to the slip clutch windings 30, 31, is electrically interconnected with the reversing switches so as to supply the current whenever these are operated to start the motor. It is operated also from the shaft 50 by means of a V-shaped cam 65; this acts upon a moving contact bar 66 which carries a guide pin 70 'and a spring 71 giving a snap-over action. The cam 65 is carried by a bush frictionally engaged with the shaft 50 so as to have a small arcuate movement therewith during its initial movement only in either direction, and thereafter to slip ; this initial movement shifts the contact bar 66 from one set of contacts 67 to the other set 66 thus opening the circuit to the windings 30, 31, and cutting off the current providing for the increased starting torque.
