Title: Improvements relating to electrical relays
IPC: H01H50/20
Filed: 1952-10-03
Abstract: 761,048. Organs. LAMBERT, S. E. Oct. 5, 1953 [Oct. 3, 1952], No. 24768/52. Class 88 (2). [Also in Group XXXVII] In an organ wherein the supply of wind to pipes such as 27, 28, 29, in response to the operation of a manual note key such as 40, is controlled by electromagnetically -operated valves such as 32, 33, 34 operation of a particular pipe requires the operation both of a note key 40 and a stop key 53 corresponding to the stop in which the pipe is situated. Operation of the note key 40 completes the circuit to a special primary relay 35 (see Group XXXVII) which renders alive a group of contacts such as 42 connected respectively to corresponding note contacts 43 associated with the various stops. The Figure shows a group of contacts 43, 44, 45, &c., associated with one particular stop and forming part of a stop selector and these contacts are connected to different primary relays 35. Energization of a stop selector magnet 52 by depressing a stop key 53 moves a bar 49 so as to bring the contacts 43, 44 ... into engagement with bus-bars 46, 47 ... connected to the valves 32, 33 ... of the different pipes of the particular stop. The pipe corresponding to the particular stop and the particular note 40 is thus sounded. A stop selector 36 may be associated with " coupler stop " selectors 38, 39 having contacts such as 59, 60, connected to primary relays operated by keys of say, an octave above or below the keys connected to the contact 43. Specification 761,047 is referred to.

Title: Improvements in or relating to devices for the correction of defects in television images
IPC: H03K6/04
Filed: 1946-08-21
Abstract: 652,153. Television. FRANCE, H. G. DE. Aug. 21, 1946, No. 24929. Convention date, Oct. 14, 1941. [Class 40 (iii)] [Also in Group XL (c)] An arrangement for correcting defects in television transmission due to variations in sensitivity in different regions of the mosaic screen of an iconoscope or inequalities in the illumination of the scene to be transmitted comprises a circuit providing a correcting voltage applicable to the picture signal voltages for each line or frame and which can be adjusted to provide a variation of the form of the correction obtained. The correcting voltages are preferably fed to the circuit from which the video signals are transmitted, but may be employed in the receiver circuit. The correction voltages are of linear or curved saw-tooth form and may be derived from a circuit fed with the scanning voltage'of the system or from a circuit generating an independent saw-tooth voltage synchronized with the line or frame scanning voltage. In the arrangement shown in Fig. 6, a condenser 1 charged at a uniform rate by the bias normally applied to a screen-grid valve 2 is discharged by the conduction of a valve 4 in response to impulses 5 which recur at line frequency. The saw-tooth wave 3 applied to the grid of the valve 2 varies the rate of charging of the condenser 1 to produce a non-linear correcting voltage as indicated in Figs. 7, 8 (not shown), depending on the phase or form of the applied saw-tooth voltage. In a modified circuit arrangement, Fig. 9, using feed-back, the grid voltage of the valve 2 is varied by an adjustable tapping point 8 on one of two potentiometer resistances connected in parallel to the output of a phase inverter valve 7 and to a condenser I<SP>2</SP> of relatively large capacity connected to a condenser I<SP>1</SP> which is in series with a condenser I of relatively low capacity, the condensers I, I<SP>1</SP> being in the anode circuit of the valve 2. The correction voltage to be applied to the line image signals is derived from the condenser I. The grid voltage for the valve 7 is taken from an adjustable tapping point 9 on the second resistance member 6 of the potentiometer so that a phase-reversed voltage is applied through condenser 10 to one end of the potentiometer of which the other end is coupled by condenser I<SP>2</SP> to the output of the valve 2. With appropriate adjustment of the tapping point 8 positive or negative feed-back may be utilized for the derivation of correcting voltages as indicated by the arrowed curves in Fig. 10 (not shown). The valve 4 is rendered conducting to discharge condensers I, I<SP>1</SP> by impulses 5 occurring at line frequency. The correcting voltages may be of a form corresponding to curves of the third degree, as indicated in connection with Figs. 7, 8 (not shown).

Patent GB-483372-A (GB)
Title: Improvements in or relating to television and other signal transmission systems
IPC: H04N5/16
Filed: 1936-09-15
Abstract: 483,372. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 15, 1936, No. 25163. Convention date, March 26. [Classes 40 (iii) and 40. (v)] During synchronizing or other pauses short wave-trains are transmitted having an amplitude characteristic of the momentary values of the lower frequency and direct-current components of television signals. At the transmitter, the higher-frequency signals pass through a high-pass filter HP1 to line L, the L.F. signals passing through a low-pass filter to a device M, shown in Fig. 4, which modulates these signals on a carrier during the synchronizing pause. At the receiving station the H.F. signals pass through filter HP2 direct to the receiver, and the short wavetrains pass to a detector D, the rectified currents passing through a low-pass filter TP2 and being superposed on the H.F. signals. The device M, Fig. 4, may comprise an oscillator O, pushpull modulator P, and an electronic relay S1 energized by impulses d synchronized with the line deflecting potentials. The detector D, Fig. 5 (not shown), includes an electronic relay (synchronized with S1) a demodulator and a low-pass filter which rejects highfrequencies produced in the electronic relay and smooths the rectified impulses to reproduce the L.F. components. The Specification, as open to inspection under Sect. 91, also states that the short wavetrains may have their phase or frequency determined by the L.F. components and describes a system in which the amplitude of the received synchronizing impulses is used to re-introduce the L.F. components. Impulses of one direction charge a condenser C, Fig. 5 (Cancelled), through a crystal or valve rectifier G, the charge on the condenser being dependent on the amplitude of the impulses and serving to determine the controlling voltage on an amplifier. Synchronizing impulses may be derived from this circuit with the aid of an additional rectifier and bias battery, Fig. 6 (Cancelled) (not shown). By using a synchronizing impulse of the form shown in Fig. 8 (Cancelled), an A.V.C. voltage may be derived, Fig. 9 (Cancelled) (not shown). This subjectmatter does not appear in the Specification as accepted.

IPC: B63B21/64
Filed: 1919-10-15
Abstract: 140,741. Soc. des Etablissements E.Feuillette. March 22, 1919, [Convention date]. Winding and paying-out apparatus on motor-vehicles; driving-gear; laying or guiding ropes on or off during winding or unwinding; stopping automatically at end of run. - Comprises a motorvehicle in which friction-disk variable-speed and reversing gearing is provided to drive alternatively the road wheels or a winch on the vehicle, the vehicle being used either as a locomotive or a stationary engine to tow boats. When used as a locomotive, at starting the roads wheels are driven and the winch is free to rotate, a brake is then gradually applied to the winch and the boat started without jerking the tow-rope. The engine a drives a transverse shaft d' through a frictiondisk b and a roller d sliding on the shaft to vary the speed. The shaft d<1> is carried by links t pivoted on a shaft f which is driven from the shaft d' by toothed gearing u. The roller d is pressed against the disk b by springs t<2> acting on the links t, the forward movement of which is limited by stops t<3>. The centre of the disk b is hollowed out so that, when the roller is central, the stops prevent it from touching the disk; in all other positions of the roller the effect of the stops and the springs is to give a varying pressure between roller and disk which is greater the nearer the roller is to the centre of the disk. The roller is traversed along its shaft by means of a chain d<4> operated by a hand wheel d<1> on the steering column. The shaft f drives a countershaft g through a train of gearing f<1>, and a pinion g<1> on this shaft can slide to drive either a winding-drum m or a differential gear h from which the road wheels are driven through reducing gearing. The rope n is guided on to the drum by a tubular arm n<1> pivoted at n<3> to a freely-rotatable turret n<4> which is mounted on a carrier o traversed along the drum by screwgear o'. The drum is controlled by a brake p. End stop devices are operated by the carrier o whereby (1) when the rope is unwound the brake p is applied, and (2) when the rope is fully wound the driving gear is disconnected. The driver's seat q is rotatable around the steering column and can be locked in either fore-and-aft position by a spring catch.

Title: Improvements in or relating to electrically driven feed mechanism for machine tools
IPC: B23Q5/32
Filed: 1951-11-05
Abstract: 720,478. Control of two motors. WOLLENHAUPT, J., and MAECKER, K. Nov. 5, 1951 [Nov. 6, 1950; April 14, 1951], No. 25878/51. Class 38 (3) [Also in Group XXII] Relates to an electrically-controlled and selfcontained feed mechanism for machine tools in which a worm wheel 1 is loosely mounted on the feed spindle and engages a shaft mounting a planet wheel geared to a high-speed motor for withdrawing the too] from the work. Another planet wheel is rigidly coupled with the first and engages a gear wheel on the feed spindle. The worm wheel 1 also engages a worm 10 carried by a hollow shaft 11 in which is rotatably mounted a shaft 12 driven through gearing by a slow-speed forward feed motor. The shaft 12 carries a helical gear 16 which engages in the hollow of the shaft 11 and transmits the drive from the feed motor to the worm wheel 1. When a part carried by the tool-holder meets a mechanical stop which is positioned in accordance with a required depth of feed (or the torque of the feed motor is increased in any other manner), the gear 16 moves out of the worm shaft and turns an arm 20 which actuates switching means for stopping the forward feed and starting the quick return movement of the tool. As shown, the arm 20 carries a transverse lever 21 which engages switch-pins 24, 25 of the limit switches 26, 27. The switch-pins operate against adjustable springs 28, 30, supported on plates 29, 31, which are adapted to engage a plate 33 associated with spring 32. In a modification, Figs. 5-7 (not shown), the shaft 12 carries a bevel wheel which drives, through two planet wheels, another bevel wheel on the shaft 11. The planet wheels are mounted on a connecting shaft, and the ends of the shaft bear against two spring-biased ramps, the inclined surfaces of which engage the pins of the limit switches. The high-speed motor may have an electromagnetic brake which slips when the torque, transmitted by the feed motor, after the latter has been switched off, exceeds a predetermined value. The switching means may be associated with a timing mechanism which commences operation when the force due to the springs which regulate the action of the limit switches is exceeded. At the end of the set period the high-speed return movement of the tool is initiated.

Title: Improvements in and relating to transformer lamp windings
IPC: H01F27/28
Filed: 1966-06-10
Abstract: 1,146,475. Transformers. SMIT NIJMEGEN ELECTROTECHNISCHE FABRIEKEN N.V. 10 June, 1966 [22 June, 1965], No. 26033/66. Heading HIT. Individually insulated conductors grouped within a further, common, layer of insulation are used to fabricate a plurality of axially aligned disc coils, each of which contains a plurality of interwound conductors, and direct connections are made from coil to coil, but not between conductors of one coil, so as to establish a current path which passes in series through conductors of at least two coils and after passing through a conductor of one coil passes through a second coil before passing through a further conductor of the first coil, or through a coil on the side of the first coil remote from the second coil. The disc coils may be grouped in interconnected pairs so that the current path performs flat outward spirals in one of each pair and inward spirals in the other. In Fig. 3 the largest surge voltage which can arise between adjacent conductors applied together is eight times that which appears in a single turn and the insulation of the individual conductors is adequate to deal with this. Larger voltages between different turns of different conductors in the same coil, such as between 2 and 17, or between conductors of adjacent coils, such as between 1 and 24 or between 5 and 44, are guarded against by the common insulation..
