Title: Improvements in and relating to electric lamp holders, plug-in sockets or adaptors and the like
IPC: H01R33/97
Filed: 1935-04-03
Abstract: 443,466. Two-part couplings. COPPING, D. C. H., 10, Warrior Square, Southendon-Sea. April 3, 1935, No. 10371. [Class 38 (i)] An electric-lamp holder, plugreceiving socket, or like electric coupling provided with means for locking a lamp or plug inserted therein comprises a. member 1, Fig. 2, with terminals for connection to current supply leads, and a member 2 with contacts or terminals within a socket which receives the lamp or plug, the member 2 being adapted for insertion in the open bottom end of the member 1 to establish contact with the current supply and provided with a projecting centre pin 6 formed with a conical head 7 which is pressed past a laterally disposed spring-loaded plunger 8 located within the member 1. The arrangement is such that when the parts are thus locked together the plunger terminals 18 within the member 2 are held against inward movement, so that the lamp or plug cannot be removed from the bayonet slots 19. The member 1 consists of a cylindrical casing enclosing an inner body 5, Fig. 4, within which terminals 15 for the supply leads are fitted. Apertures 3 in the member 1 align with apertures 4 in the member 5 to receive screws which hold those members together and also serve to secure them to a support. The lower ends of the terminals 15 form sockets to receive spring plungers 14, Fig. 6, on the upper face of the member 2, these plungers being located within sheaths 16 carrymg downwardly extending pins 17 with heads 18 on their lower ends to form contacts for a lamp inserted in the socket. Compression springs 20 surround the pins 17. A lamp is inserted in the socket of the member 2 before the latter is fitted into and locked within the open end of the member 1, the subsequent fitting of the member 2 and insertion of the plungers 14 into the terminal sockets 15 producing an axial pressure on the pins 17 which prevents rotational movements of the lamp to disengage its pins from the recessed ends 19<a> of the slots 19. The spring-pressed plunger 8 can be disengaged from the head 7 of the member 6 by means of a removable screwthreaded pin 11 provided with a head 13. To enable the holder to be used without employing the locking-device a pair of sockets are provided adjacent to the sockets 15 to receive, and make contact with, the plungers 14 while allowing the plungers 18 freely to move axially.

Title: Regulated alternating current power supply
IPC: H02M7/538
Filed: 1963-03-15
Abstract: 1,034,474. Transistor inverter circuits. HAGAN CONTROLS Ltd. March 15, 1963 [March 23, 1962], No. 10472/63. Heading H3T. The voltage across the primary winding of the output transformer of a transistor inverter oscillator is limited by voltage control means operating through emitter follower action of the transistors. As shown, the voltage control means comprises a Zener diode 37, a battery B and also diodes 38, 39 which respectively conduct when the associated transistor is conductive to limit the voltage at the respective base and thus at the emitter. Accordingly, the primary voltage is fired and thus also the time for the transformer to reach saturation so that the frequency of operation and output voltage are independent of supply voltage. Resistor 45 supplies a starting bias.

Abstract: 215,388. Aktiebolaget Formator. May 4, 1923, [Convention date]. Cigar and cigarette making machines. - A machine adapted to apportion tobacco for cigars is provided with means to eliminate differences in bulk of the portions delivered. A casing 1, Fig. 2, of approximately rectangular section is mounted on a reciprocating slide 14 and contains a reciprocating piston 6 of corresponding section. The casing 1, which may be flared in a downward direction, is closed at its lower end during a part of its stroke by a knife blade 12 carried by two bell-crank levers 10 pivoted at 7 to the exterior of the casing. The blade 12 is swung about its pivot by levers 11 engaging the levers 10 by means of arcuate toothed racks 10', 11<1>. The levers 11 are fixed on a shaft 21 which moves with the slide 14 and is rocked by a rod 23 through the medium of an arm 22. A portion of tobacco is fed mechanically or by hand into the casing 1, which already contains one or more such portions, through a hopper 5. The casing and piston then descend, the knife 12 is swung aside and, as shown in Fig. 5, the tobacco is compressed to a predetermined volume against a table 16, the casing 1 rising in advance of the piston 6. The exposed portion of the tobacco, which is a given fraction of the whole quantity, is then cut off by the knife 12. The hopper 5 may be replaced by two vertical plates which grip the tobacco portion and may form part of a reciprocating feeding-mechanism delivering tobacco to the top of the casing 1. The tobacco is pressed from between the plates into the casing by the piston 6. The volumes of the tobacco portions fed into the casing 1 may be multiples or sub-multiples of those cut off. The apparatus may be so arranged that the tobacco in the casing may be wholly divided into portions before further portions are delivered thereto. The Specification as open to inspection under Sect. 91 (3) (a) also describes the invention as applicable to the preparation of tobacco portions to be made into cigarettes or to be packeted. This subject-matter does not appear in the Specification as accepted.

Abstract: 767,263. Rectifying. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 17, 1953 [May 3, 1952], No. 11227/52. Class 38 (2). [Also in Group XL (c)] In a cathode-ray tube circuit comprising a timebase coil 1 in the anode circuit of a driving valve 4 and means for deriving E.H.T. voltage for the tube from the flyback of the timebase current waveform, a rectifier or diode 11 and a capacitor 16 are connected in series across said coil 1, and a network comprising a focus coil 12, resistors 13, 15 and potentiometer 14 is connected across capacitor 16 such that variations in the focus due to variations in the E.H.T. and the power supply or the timebase amplitude control are reduced. Potentiometer 14 controls the focus and variable resistor 15 controls the amplitude of the timebase. If the main focusing is effected by a permanent magnet, coil 12 constitutes an auxiliary means for effecting focus adjustments. The control signal applied to the grid of valve 4 includes periodic negative pulses which cut off valve 4 during the timebase flyback and the control signal may be shaped to ensure linearrity of the timebase waveform. In Fig. 1 the means for generating the E.H.T. comprises adjustably-coupled coils 3 and 17, rectifier 18 and storage capacity 19, the E.H.T. circuit being tuned by the leakage inductance of the coil 17 and by the stray capacity 22 to series resonance at a frequency equal to that of the undesired ringing oscillations in the scanning coil circuit so that similar ringing oscillations are produced in the E.H.T. circuit and due to the coupling between the coils 3 and 17 the two sets of ringing oscillations effectively cancel each other in the scanning circuit. In a modification, Fig. 2 (not shown) coils 3 and 17 are replaced by a single coil connected as an auto-transformer and the current waveform in coil 1 is linearized by connecting the lower end of coil 1 and the cathode of rectifier 11 to separate tappings on the autotransformer coil. The H.T. for valve 4 may be boosted in a known manner by connecting a further capacitor between the upper terminals of coil 1 and capacitor 16; alternatively the capacitor 16 and focus coil network may be connected as shown in Fig. 3 in which case capacitor 16 functions as a boost capacitor. Specification 767,265, [Group XL (c)], is referred to.
