Title: Improvements in and relating to synchronised electric drives for printing presses and like machines
IPC: H02P5/50
Filed: 1933-12-02
Abstract: 430,074. Master control of D.C. motors; maintaining equal speeds. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Wright, W. L. ; 305, 5th Street, Scotia, New York, U.S.A.) Dec. 2, 1933, No. 15689/35. Convention date, Dec. 2, 1932. Divided out of 429,837. [Class 38 (iii)] The individual driving motors of the units of a printing press are coupled to interconnected alternating-current synchronizing motors and, for maintaining uniform low speed, an alternating voltage is supplied to the secondary windings of the synchronizing motors, having a frequency different from the frequency of the supply to the primary windings. The secondaries of the synchronizing motors are connected to bus-bars 55 to which an auxiliary generator 120 is connected for low speed operation. The generator 120 is driven from the shaft of a generator supplying the unit driving motors, through gearing such that it generates at a frequency exceeding that of the supply 48 to the primary windings of the synchronizing motors by an amount proportional to the desired low speed. A switch 121 between the generator 120 and the busbars 55 is closed in response to the closure of supply circuit to the unit driving motors, and is provided with a time device 125 whereby a clutch 123 through which the generator 120 is driven is uncoupled while the connections are being established. The Specification also describes with reference to Figs. 1 and 3, not shown, arrangements identical with those shown in Figs. 4 and 6 of Specifications 429,837 and described with reference thereto.

Title: Improvements in chucks
IPC: B23B31/173
Filed: 1921-06-07
Abstract: 164,350. Breitenbach, K. June 7, 1921. Chucks.-In bevel closing chucks of the type in which the jaws are actuated by an axially movable bevelled member, detachable connecting pieces are provided between the jaws and the actuating member. Jaws 2, Figs. 1 and 2, have ribs radially guided in grooves 18, 19 in a chuck body 1 mounted on a member 12 adapted to be secured to the machine spindle, and inclined rear faces 2 coacting with corresponding faces provided on a member 4 keyed at 8 to the chuck body and moved axially by means of a nut 7. The latter is secured against axial movement by a ring 10. The inclined faces on the member 4 may consist of detachable dovetail members 6 having projecting ribs engaging grooves 16 in the jaws so that the latter are positively actuated in both directions. In a modification, Fig. 3, each jaw has two converging inclined faces and the members 4 having right and left-handed threads are simultaneously moved in opposite directions by rotation of the nut 7. In a further modification the member 6 consists of a strip of rectangular section and the jaws are retained in the member 4 by 'means of tongues sliding in grooves formed in the sides of the jaws. A number of further methods of securing the jaws to the axially-moving member 4 are described. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also a modification, Fig. 19 (Cancelled), adapted for internal chucking, a threaded centrally-disposed member 4 being moved axially by a nut 7 actuated by bevel gearing 40. The gripping surfaces of the jaws are of thread formation so that any slipping which may be caused by the pressure of the tool tends to draw the work against the chuck body. A further modification is adapted for use either as an internal or external chuck. Various methods of actuating the member 4 controlling the jaws are also described. This subject-matter does not appear in the Specification as accepted,

Title: Improved wide band tunable oscillator
IPC: H03B5/18
Filed: 1966-04-07
Abstract: 1,124,179. Valve oscillating circuits. TRAK MICROWAVE CORP. 7 April, 1966 [7 April, 1965], No. 15751/66. Heading H3F. [Also in Division H1] The invention relates to a microwave oscillator of the type comprising a valve 32 mounted coaxially within one end of a tubular outer cavity 12. The valve is supported by clamping of its cathode ring 38 between an insulating ring 46 and a conductive inner tubular member 48, which is separated from outer cavity 12 for D.C., by insulating material 56, the arrangement providing an effective short-circuit for R.F. The anode 34 supports a coaxial inner conductor 62 over which slides a turning member comprising sleeve 74, which terminates in a quarter-wave choke 76. A further tubular member 110 is supported on the grid ring 36 of the valve, being disposed coaxially between the outer cavity 12 and inner conductor 66 to produce grid-anode and grid cathode-cavities, but being limited in length so that an anode-cathode cavity occurs beyond it. According to the invention, member 110 is made of conical form so that an increased capacity occurs between its outer end and sleeve 74, thus reducing the minimum frequency to which the arrangement will tune. According to a further feature of the invention, the minimum frequency may be reduced still further by providing the sleeve 74 with an enlarged end 74b. Sleeve 74 is split longitudinally and provided with in-turned end portions 74a which slide on member 62; this member may also be made conical in form to assist in reducing the minimum frequency, (Fig. 5, not shown). The grid member may be grooved internally in a longitudinal direction, the grooves containing bi-metallic strips which provide temperature compensation.

Title: Improvements in or relating to the making of latex sheeting
IPC: B29C41/14
Filed: 1937-06-09
Abstract: 496,761. Rubber sheets ; moulding by dipping. SPANEL, A. N. June 9, 1937, No. 16000. [Classes 70 and 87 (ii)] Rubber sheeting is made by deposition from latex on a long band which is in a fixed wound or bent condition. A band 5, Fig. 4, of stainless steel, aluminium, or the like is wound temporarily or permanently into a spiral, and is held in position by spacer bars 20. This is dipped edgewise into a bath 22 of latex, withdrawn, and allowed to drain while drying, to form a reinforced lower edge 24, Fig. 2. The former is turned over, and the operation repeated to form a reinforcement on the other edge. The strip shown has transverse ribs 15, in the angles of which rubber accumulates to form rectangular sheets reinforced all round. The form of the edge reinforcement may be determined by grooving, tapering, or otherwise modifying the edge of the band 5. By enlarging one end of the band, e.g. by looping it back on itself, the rubber deposited on both sides of the band may be obtained as a single sheet, of twice the length of the band. The sheet may be vulcanized before or after stripping from the band. In a modification, the band is bent into serpentine form. Dipping may be replaced by spraying, and drying by acid coagulation.

Filed: 1970-04-08
Abstract: 1317266 Rectifier assemblies GENERAL ELECTRIC CO 8 April 1970 [23 April 1969] 16749/70 Heading H1K A rectifier assembly comprises one or more pairs of series-aiding rectifier elements clamped between an electrically conductive heat sink and another electrically conductive member so that the sink engages one pole of each pair and the member the other pole. A lead is connected to the junction between the elements and means is provided to passivate the surfaces of the elements and to co-operate with the heat sink and member to form a protective enclosure for the elements taken as a whole. In the 3-phase rectifier assembly of Fig. 4 the heat sink, forming part of an alternator easing, has parallel ribs 120 on one face and radial ribs 106 on the other and its dished centre is apertured to provide an annular ledge around which three pairs of rectifier elements are angularly spaced. The elements passivated with glass or silicone rubber 144, are potted in silicone, epoxy or phenolic resin 150 and an 0-ring 128 seals the gap between the heat sink and conductive member 124. Each pair of elements has a common centre contact strip 148 which extends through a slot in lock coupler 152 which is formed with reinforced peripheral projections. In mounting the assembly these are slid between inwardly projecting fingers on the heat sink, the coupler rotated to bring them behind the fingers and bolt 160 tightened to clamp the assembly. If the other side of the sink is accessible the coupler may instead have an annular locating flange and may in any event be cast integral with the potting. In another assembly the rectifiers of each pair are located on opposed faces of a dielectric annulus on printed conductive tracks which extend outwards to apertured ears where they are joined by a hollow rivet. This assembly is mounted to a heat sink by a central bolt 228 (Fig. 7) with cup 238 forming the other conductive member. In a simpler arrangement (Fig. 8, not shown), in which a bolt presses the assembly against the sink via a spring washer, potting material extruded through a bolt hole provides a stop preventing undue tightening, while in another the phase input leads enter near the periphery of the arrangement and are curved around the central mounting bolt. A more compact arrangement comprises, between two mounting plates, a wafer (Fig. 11) comprising three diode rectifiers mounted face to face with a complementary wafer via sectorial phase plates extensions of which protrude through a surrounding annular glass seal.

A hank-opening device has a number of parallel supports 3, Fig. 1, that are movable from a closed position (shown in full lines), to an expanded position (shown in broken lines) by means of arms pivoted at 2 on a common circle. Each shaft 2, Fig 3, has secured thereto an arm 17 that is spring biased against a dog 15a on a toothed segment 15, freely mounted on the shaft 2, the toothed segments of the various shafts 2 meshing with a common drive pinion 8. When the pinion 8 rotates clockwise, all the toothed segments 15 rotate anti-clockwise thus causingthe dogs 15a to abut the arms 17 and cause the parallel supports 3 to move apart simultaneously and equally. When the pinion 8 is rotated in the opposite direction the parallel supports 3 close together unless prevented by an obstruction, in which case the segments 15 continue their motion and leave the spring biased arm 17 behind at the setting at which the obstruction was met. According to a modified arrangement the arms 17, dogs 15a, and spring means, can be replaced by a positive dog-coupling effective in the opening direction and a slipping clutch coupling effective only in the closing direction, the transmittable torque of the slipping coupling being adjustable.

Abstract: 670,698. Piston packing. DYSON, G., and DYSON, W. June 22, 1949. [June 23, 1948] No. 16878. Class 122(i) In a sealing device for a piston the pressure in the cylinder is caused to act radially upon the outer face of  a  pressure ring, the inner face of which is inclined and is adapted to work slidably against an oppositely inclined surface whereby relative movement between the inclined surfaces causes an end face of a packing ring to be forced closely into contact with the surface of the ring groove. A piston a, Fig. 1, is recessed at a<SP>1</SP> to accommodate a sealing ring c and at a<SP>2</SP> to accommodate a pressure ring d, the ring d and recess a<SP>2</SP> having inclined mating surfaces as shown. The pressure medium has access to the outer face of the ring d, which may also have a step d<SP>1</SP> exposed to the pressure medium, which forces the ring d to seat on the ring c and presses the latter against the surface a<SP>3</SP>. In a modification, Fig. 2, the piston is recessed at a<SP>1</SP> and the recess accommodates the ring c and a ring e having an inclined surface mating with the ring d. It is stated that radial pressure exerted on the pressuring ring plus the axial pressure on the shoulder d<SP>1</SP> tends to cause the ring to slide on the inclined surface of the ring e and thus to exert pressure on the packing c.
