Patent GB-478351-A (GB)
Abstract: 478,351. Inductor alternators; starting prime movers. WICO ELECTRIC CO. June 15, 1936, No. 16607. Convention date, June 15, 1935. [Classes 35 and 38 (iv)] [Also in Group XXVII] Battery current is directed at engine-starting into the primary winding 15 of an inductor alternator and during normal running to the energizing coil 9 of an electromagnet of which an enginedriven magnetizable shaft 8 forms the core. Laminated radialarmed inductors 10, 10<1> are secured to the shaft on each side of the coil, the arms of one set being staggered relatively to those of the other. An induction coil with a soft-iron core 14 and primary and secondary windings 15, 16 surmounts the electromagnet and inductors, pole-pieces 18 being also secured in the casing and having arcuate faces concentric with the shaft 8. A centrifugal governor 57 is interposed between the driving shaft 54 and shaft 8 which at the other end, is extended to carry the cam 36 for interrupting the primary circuit and the arm 50 by which the high tension current is distributed to the sparking-plugs. In lateral extensions of the main casing are mounted the condenser which is connected across the interrupter terminals and an electromagnetic switch determining the circuit conditions for starting and normal running. As shown in Fig. 9, after the ignition switch I and the starting switch S have been closed, the starting motor M and the electromagnetic switch 89 are energized. The armature 90 is attracted hereby, breaking the earth connection 95 to prevent the electromagnet 9 from being energized, and closing a circuit from the contact 97 to lead 98 and the primary winding 15 which, due to the action of the engine-driven interrupter 36, induces hightension current in the winding 16. As soon as the switch S is opened the circuit through the electromagnet coil 9 is re-established.

Title: Television deflection coil assembly
IPC: H04N3/16
Filed: 1974-11-06
Abstract: 1488525 Electron beam electromagnetic deflecting systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 Nov 1974 [9 Nov 1973] 47981/74 Heading H1D [Also in Division H4] The invention is concerned with the elimination of interference oscillations in the deflection currents of deflection coil assemblies for Vidicon type colour TV camera tubes for example comprising two line coil and two frame coil sections together with conventional (earthed) electrostatic screens. Such oscillations, are situated around approximately 0À2 MHz and 1À0 MHz, the former being due to excitation of the frame coils by the line deflection signals and the latter by interaction between a line coil section and the conventional electrostatic screen which behaves as a distributed capacitance between the turns of the line coil section and earth. In accordance with the invention both oscillations are eliminated by the provision of an additional electrostatic screen connected to the non- earthed side of the line deflection coil(s). Figs. 1 and 2 show the general arrangement of the deflection coil assembly which comprises line coils 11 and frame coils 12 each arranged, respectively, as two sections 22, 23 and 20, 21, together with conventional electrostatic screens 13, 14 focusing coil 16 and a ferromagnetic winding 17 which serves inter alia to intensify the deflection fields. Additionally, and according to one aspect of the invention a further electrostatic screen 15 is included in the assembly. Fig. 3, shows the general circuit arrangement in which the screens 13 and 14 are connected to earth whilst the screen 15 is connected to the non-earthed end of the parallel connected line coil sections. With this arrangement, when the line coil sections 22, 23 are wound in opposite directions, the oscillations at 0À2 MHz are eliminated and the screen 15 then substantially eliminates the oscillations at 1À0 MHz. In practice, however, residual capacitive coupling between the line and frame coils may have a disturbing effect which is compensated by the arrangement shown in Fig. 3, in which oppositely phased line frequency is derived from a transformer 40 and supplied via capacitor 43 to the centre-tap of the field deflector coils 20, 21. The transformer may comprise a winding on the ferromagnetic core 17. Fig. 5, shows an arrangement for "reversed line scanning" employing a change-over switch 50 in which, to eliminate the oscillations, two additional electrostatic screens 51, 52 are employed connected respectively to opposite end of the line coil sections. Fig. 6 shows a further arrangement in which, when the line coil sections are connected in series, one electrostatic screen 62 is connected to the non-earthed side of the system whilst a second electrostatic screen 61 is connected to the centre tap of the line coil sections 22, 23. Numerous modes of connection of the coil sections are disclosed.

Filed: 1970-10-13
Abstract: 1338577 Supplying and collecting bobbins LEESONA CORP 13 Oct 1970 [21 Oct 1969] 48508/70 Heading D1F An automatic spinning and winding system comprises a "self-tending" spinning apparatus operable to position empty bobbins, fill them with yarn and transfer them to handling apparatus which automatically delivers these bobbins to "self-tending" winding apparatus which receives and positions the bobbins, unwinds yarn therefrom and subsequently returns the empty bobbins to the handling apparatus for return to the spinning apparatus. The handling apparatus may be controlled in response to the demand for wound and/or empty bobbins, perhaps sorted as to type and transferred in equal batch, within the system and to this end includes bobbin storage equipment. In the system 14 shown, each spindle frame 16 in a spinning area 12 feeds its filled bobbins 20 (of a type which may differ from other types used in the system) by a chute 18 to a storage and conveyor bin 22 whence batches formed in a weighing hopper 26 are successively transferred to one of containers 30 on an overhead conveyor system 32 for delivery to a winding area 36. Each winding machine 38 receives by one of chutes 40 and orienting apparatus 82 according to type full bobbins 20 which are unwound at winding stations 42 and rewound into yarn packages (not shown). The resultant empty bobbins are first automatically delivered by conveyors (not shown) one for each type of bobbin, to hoppers 46 thence to a container 30 for return to area 12 whereat they are deposited in an appropriate one of strippers 48 which remove residual yarn. Empty and stripped bobbins then pass automatically to storage and conveyor bins 50 whence they are delivered by chute 52 to orienting and delivery hopper 54 for reuse by the associated spinning frame 16. The movements of the bobbins are so controlled as to maintain a predetermined minimum spacing therebetween. (For Figures see next page)

[Also in Division H2] A system for actuating components of an underwater installation from a position remote from the installation includes a coupling for transmission lines and one member of the coupling is mounted on the installation. An electrohydraulic system (Fig. 1, not shown) is adapted to operate the blow-out preventers and connectors of an underwater wellhead from a barge and the coupling members for the system are shown in Figs. 2, 3. One member 49 is mounted on the wellhead and has pairs of hoses such as 111, 112 connecting each component to ducts such as 65, 66 extending from the sealing surface 70 which has seals 71. The ends of the ducts are normally closed by a spring pressed sleeve 59. The other member 76 is suspended from a barge by an electric cable 110, the strands of which are connected to a motor 108 driving a pump 96, and to four-way valves, such as 93, 105, 106. Each valve such as the valve 93 is connected to ducts such as the ducts 91, 92 leading to the internal surface of the wall 78, and to a duct 5 leading to the pump and to the reservoir 98 formed within the member. The member 76 is lowered and locked to the member 49, displacing the sleeve so that a pair of ducts such as 91, 92 is connected to a pair of hoses such as 111, 112 connected to a component. Current supplied to the motor and a valve causes fluid to actuate the appropriate component. In a modification (Figs. 6-8, not shown) a probe on the member suspended from the barge engages a bore in the member fixed to the wellhead. In the construction shown in Fig. 9 the connecting members are adapted for wellheads employing electrically actuated components. The member 152 suspended from the barge has a probe 153 adapted to engage within a tubular member 159 attached to the wellhead. The probe has electrical leads (not shown) connected to a series of contacts 154, 155, 156 ... which are adapted to engage a series of conductor rings 157, 163, 164 ... located within the member 159. Each group of three conductor rings is connected to a three phase motor actuating a component. The system may be for the primary or secondary control of the components. In a further modification (Fig. 12, not shown) the components of an underwater production wellhead are actuated by means of a control cable which runs along the ocean bed to the shore or a control station.

Abstract: 1371914 Automatic frequency control; frequency detectors SIEMENS AG 21 Oct 1971 [13 Nov 1970] 48895/71 Heading H3A In an oscillator a.f.c. circuit: the output of a frequency modulated oscillator 02, is compared with a reference frequency from a stable, e.g. crystal, oscillator O1 in a control loop containing two mixers M1, M2, one of the signals being applied to both mixers in phase, and the other being supplied to both mixers in quadrature, e.g. via phase shifters RC, RL; the output of one mixer M1 is fed to an integrator 3G1 ; the output of the other mixer M2 is fed to a differentiator DG; and the outputs from the integrator and differentiator are fed to a circuit AS, SS, GR which compares their phase difference to produce a rectified control voltage for the oscillator 02. The difference frequency outputs of the two mixers are in phase quadrature, and the integrator and differentiator function as low and high pass filters respectively to give a further phase shift to the difference frequency components so that the resulting signals U1 are either in phase or in antiphase. The signals Ul, U2 are then fed to sum and difference circuit AS, SS, the outputs from which are rectified, filtered and combined in amplifier GV to provide the frequency control signal for oscillator 02. In a transistorized circuit form, Fig. 5 (not shown), the sum and difference circuits comprise two transistors (T s 6, T s 7) connected as a long-tailed pair, with a third transistor (T s 5) as the "tail". The signal from the differentiator (C16, R16) is applied to the third transistor and thus arrives at the collectors of the other in the same phase. The signal from the integrator (R13, C14) is applied to the other two in push pull, so that sum and difference components occur at the collectors of these transistors (T s 6, T s 7).
