Title: Improvements in and relating to coil winding apparatus
IPC: B65H54/28
Filed: 1956-07-06
Abstract: 837,284. Winding wire; traverse mechanisms. GENERAL ELECTRIC CO. July 6, 1956 [July 8, 1955], No. 21052/56. Classes 120(2) and 120(3) [Also in Group XXXV]  In coil winding apparatus a first member holding a device for guiding a material to the point where it is wound to form a coil, is constrained to a straight movement parallel to the axis of the coil and is arranged to be reciprocated by a similarly constrained second member through the intermediary of a lever, a support for the fulcrum of the lever being held by a setting mechanism allowing adjustment of the location of the fulcrum along a line parallel to the axis of the lever and thereby adjustment of the ratio of the lever arms and of the rciprocating movements of the two members. In the arrangement shown motor 1 drives the winding shaft 5 through belt 2 and a drive is taken from shaft 5 by shaft 7, gear box 8 and shaft 9 to cam 10. The rotation of cam 10 imparts a reciprocating motion to arm 11 through followers 12 and 13, the latter being spring urged against the cam. The arm 11 is pivoted to a lever 18, to the other end of which is pivotedly connected a further arm 17 which reciprocates a support member 30 carrying a guide 31 and adhesive application means 32. The fulcrum of lever 18 is at the end of a pivotal mounting 23 which is vertically adjustable by screw 26 rotatable by handle 27 and having a graduated dial 28 so that by altering the position of the fulcrum and thereby the relative lengths of the two parts of lever 18 the length of the traverse of the support 30 can be varied. The coil is wound on a square former 34 the corners of which are chamfered and serrated, 35, such that the first layer of wire is uniformly spaced along the former. The second layer is wound into the grooves formed between the turns of the first layer and so on.

Title: Improvements in and relating to controlled directional gyroscopes
IPC: G01C19/36
Filed: 1943-12-21
Abstract: 606,646. Fluid-pressure servomotor-control systems. STEVENS, A. H. (Sperry Gyroscope Co., Inc.). Dec. 21, 1943, No. 21426. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 25, 1946.] [Class 135] [Also in Groups XX and XXXVIII] Precession in azimuth of a gyroscope is obtained by applying torques through a mechanical linkage between control members mounted for rotation about the vertical axis of the gyroscope and the rotor bearing frame so that the latter receives a torque about its horizontal axis. As shown, the invention is applied to a gyro-magnetic system in which repeaters acted on electrically or pneumatically by the magnetic compass are mounted for rotation about the vertical axis of the gyro and act through a mechanical linkage to apply a torque to the rotor bearing frame about its horizontal axis so as to cause the gyro to precess in azimuth, driving the repeater until the misalignment signal disappears. In all arrangements shown, a repeater is mounted at each end and its rotor is coupled to a bevel gear 20, 20<SP>1</SP> meshing with a third bevel wheel 21 on the horizontal shaft 6 of the gyro frame. In one arrangement, Fig. 1 and Fig. 2 (not shown), the repeaters comprise crossed coil stators and permanent magnet rotors in a system similar to those described in Specification 555,788, [Group XXXVIII], in which capacity pick-offs on the magnetic compass vary the distribution of current from a local oscillator fed via rectifiers to the repeater stators. In the present case, however, the rotors are ring-shaped with externally projecting polepieces. In another arrangement, Figs. 3 and 4 (not shown), the transmitting arrangement is a flux-valve and the receiver a selsyn. As shown, air jets 42, 43 and 42<SP>1</SP> and 431 co-operate with eccentrically mounted discs 40, 40<SP>1</SP> on the transmitter and receiver shafts. When these are in correspondence, the differential pressures in gauges 46, 47 are equal. When any difference arises, air is admitted to drive the receiver turbine wheels in the appropriate directions, the resulting torque on the gyro frame about its horizontal axis causing the gyro to precess until it is in positional agreement with the distant compass. Specification 377,262, [Group XX], also is referred to.

Title: Improvements in or relating to a method and apparatus for forming a pocketed web
Inventor: VOGT CLARENCE WEDEKIND
IPC: B65B47/10
Filed: 1968-05-07
Abstract: 1,224,393. Moulding containers. C.W.VOGT. 7 May, 1968, No. 21446/68. Heading B5A. [Also in Division B8] An apparatus for forming sealed packages comprises a rotating drum 19 having a plurality of pocket-defining recesses 27 in its peripheral surface, means for supplying web-forming liquid to the periphery of said drum, means connected to the drum for sequentially drawing a vacuum in each recess to draw the liquid against the drum's peripheral surface and into the recesses, forming pockets in the web, and then venting the recesses to release the web. In one embodiment, Fig. 1, the web is formed from a curtain 59 of liquid falling from a tank 52. The drum 19 has one or more rows of recesses 27, Fig. 2, in step with which are apertures 48, Fig. 1, of a belt 47 which carries the newly-formed pocketed web between a belt of vacuum-producing units 67 and a set of orbiting filling units 75 preferably of the gaseous pressure differential type, after which the pockets are sealed with a web 85. Unused liquid is caught in a trough 55 and re-circulated, and the tank itself may be pressurized and thermostatically heated. The base of each drum recess 27 comprises a filter block 30, Fig. 2, connected via pipes 34 to orifices in the disc 24 supporting the drum. A valve plate 38 has two arcuate passages 42, 44, with which the apertures 37 communicate, the passage 42 being connected to a vacuum line and the passage 44 being connected either to a pressurized line or to the atmosphere. The belt 47 is preferably of metal, e.g. stainless steel, and may be coated with a sealing material, e.g. rubber. Holes 50 in the belt are engaged by pins 49 on the drum. The orifice (62) of the tank 52 is enlarged at points (63), Fig. 3 (not shown), above the ends of the recesses 27. Each filling unit 76, which may incorporate weighing means, comprises a vertically movable filling head connected to a hopper 81 by an extensible duct 82. As the filling units preferably create a partial vacuum in the web pockets, a similar vacuum is introduced beneath the web through filter blocks 70, Fig. 7, in the units 67, which are engaged with the aid of pin-and-slots 79, 80 with the filling units, and evacuated through channels 71, 72, and 83, therefrom. The cover web 85 may be pressure or heat sealed to the web 60. Individual packages may be severed from the web, or groups of four, which may be folded to form a square package. In another embodiment, Fig. 8, the endless belt 47 is replaced by a roll 91 of material 90, e.g. cardboard, of similar construction, and the drum 93 has notches 95 instead of pins. The web 90 is positioned on the drum by star wheels 96. The web 60 bonds itself to the web 90. In a further embodiment, Fig. 9, articles 109 to be packaged are conveyed on a web 108 beneath a newly-formed pocketed web 104, and on an endless belt 106. The webs are sealed by adhesives or heat, and the pockets 105 are shrunk beneath a heater 111. Individual packages are severed from the web.

Filed: 1963-05-29
Abstract: 1,038,076. Automatic voltage control. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. May 29, 1963 [May 29,1962], No. 21460/63. Headings G3R and G3X. [Also in Division H2] The electric heating system of a dieselelectric or turbo-electric train is energized from the main generator of the locomotive over a voltage regulator which maintains constant the voltage applied to the system. As shown, a transformer 21 is connected to the generator terminals 20 and supplies a heating load, connected to terminals 25, over a rectifier bridge 30 constituted by controllable rectifiers producing a constant output voltage under the control of a regulator 31. For an A.C. output, two controlled rectifiers may be connected back-to-back between the transformer 21 and the output terminals 25 (Fig. 4 not shown). In another modification (Fig. 2 not shown) a switching device, connected between a rectifier and the output terminals 25, is controlled in dependence upon variations in the output voltage of the rectifier to maintain constant the voltage at the terminals. The transformer 21 may have an adjustable transformation ratio, and the voltage regulator may comprise a transductor.

Title: Improvements in or relating to damping apparatus for electrical instruments, meters and relays
IPC: G01R11/10
Filed: 1943-12-23
Abstract: 574,894. Electromagnetic ammeters and voltmeters ; power meters ; supply meters. NALDER BROS. & THOMPSON, Ltd., and LIPMAN, C. L. Dec. 23, 1943, No. 21534. [Class 37] [Also in Groups XXXII and XXXVII] An instrument, meter, or relay has an induced eddy-current damping or braking device which comprises a rotor arranged to move in a concentric magnetic field provided by a cylindrical or disc-shaped magnet situated in close peripheral proximity thereto whereby the concentric field is cut by the rotor simultaneously at positions continuously or substantially continuously angularly displaced around the axis of the rotor. A drum type rotor 1, Fig. 1, is mounted on a spindle 2 so that its cylindrical portion is disposed in an air gap formed by an internal cylindrical magnet 3, magnetised along a diameter, and a soft iron ring 4. Alternatively the magnet may be outside the rotor and a soft iron core inside, or internal and external magnets may be employed. Magnetic shields 5 shield the movable system or windings of the instrument or relay from the field of the magnet 3. The cylindrical surface of the rotor mav be cut away as shown in Fig. 5 to produce a different degree of damping for a centre-zero instrument at the centre of the scale, or as shown in Fig. 6 to give a progressively variable degree of damping. The magnet 3c, Fig. 7, may be provided with polar projections N1, S1, which may be integral with the magnet or of soft iron and attached thereto, the soft iron ring 4c being provided with corresponding projections 4p, 4p<1>. The magnet may be slotted as shown to facilitate assembly. The soft iron path may be arranged above the magnet instead of surrounding it. A soft iron member 6, Fig. 9, may be arranged to bridge the poles of the magnet 3e and may be movable angularly to vary the flux distribution in the air gap. Alternatively this member may be fixed opposite one pole of the magnet. The damping device may be applied to moving iron instruments of the attraction or repulsion type, to dynamometer instruments or relays, and to induction type integrating meters, instruments, or relays. Fig. 18 shows a timing relay having a spindle 25 on which is arranged an arm 26 which impedes the movement of the contactcarrying arm 27. When the arm 26 is displaced the rotor 1m of the damping device is driven by a spring and clutch 28 through gearing 29, and the movement of the arm 27 towards the fixed relay contacts 30 is consequently damped with a resulting time lag action. Instead of being magnetised along a diameter, the magnet may have its opposite poles spaced along the rotor spindle. The member 6, Fig. 9, may be replaced by a similarly shaped permanent magnet, a soft iron ring being arranged inside the rotor. The permanent magnets may be replaced by electromagnets.

Title: Improvements relating to the manufacture of crystalline material
Inventor: BILLIG ERNST
IPC: C30B15/00
Filed: 1953-08-05
Abstract: Semi-conductor material having a crystalline structure of co-ordination number less than 8, e.g. the diamond, zinc blende or wurtzite structure, is obtained in the form of thin laminae having surfaces of optical flatness or better by withdrawing from a melt of the material at a temperature near its melting point a crystal seed oriented so that the withdrawal direction is in a plane of highest atomic packing.  Preferably this is the [211] direction. Crystallization occurs in thin wafers in the extended plane of highest atomic packing.  Materials referred to are silicon, germanium and binary compounds of elements from Groups 3 and 5 or 2 and 6.  By holding the melt in a narrow crucible and orienting the seed so that a plane of highest packing is in the length of the trough growth may be confined to this direction.  Where practicable the melt may be held in a spherical shape by surface tension or levitation in an alternating electric field to avoid contact with a crucible wall. The formed crystals should be annealed after growth.  In an example a germanium seed was withdrawn at the rate of 2mm. per second from a germanium melt held at 10 DEG C. below its equilibrium freezing temperature.
