Title: Improvements in devices for supporting overhead electric conductors
IPC: H02G7/05
Filed: 1930-03-01
Abstract: 354,171. Supporting overhead cables. HIGHFIELD, J. S. and HIGHFIELD, W. E., 36, Victoria Street, London. March 1, 1930, Nos. 6853, 17486, and 27032. [Class 36.] A cable clamp comprises symmetrical elements 1, 2, each consisting of an upper part having a flange 3 and a lower part 4 secured to the upper part by screws 5. A double-conical member 6 cut to form a series of longitudinal ribs 7 connected by a web 8 fits within conical grooves in the elements 1, 2. The member 6 is split for assembly round the cable 9. Bolts 10 draw the elements 1, 2 together to exert the degree of gripping pressure desired on the cable 9. In the modified construction shown in Figs. 4 and 6, the clamp is built up from parts 13, 14 which have flanges 15 formed with registering apertures for reception of a shackle 12. A split double conical member 6 is assembled round the cable 9 and is engaged by internally conical split members 16 which are forced over the ends of the member 6 by members 17 which are screwed into the ends of the clamp body. The members 17 are formed in halves held together by pins 19. In a further modification the body is built up from two parts formed with central inwardly projecting flanges. Two pairs of split conical members are fitted on each side of the central flanges which form abutments for the male members of the inner pairs. The male members fit female members which are prevented from expanding by the walls of the body parts. The female members abut against the broad ends of the male members of the outer part which in turn enter the female members of the outer pairs. Abutment members, adapted to exert longitudinal pressure on the conical members, are forced towards each other and into the body by bolts which run outside but parallel to the body. In a further modification, the body parts have cylindrical lateral projections which receive bushes adapted to act as bearings for arms extending upwards from the clamp. The arms form attachment means to an insulator or shackle and are bolted together through a distance piece. In another modification the body parts have cylindrical recesses which receive bushes constituting bearings for threaded pins which screw into arms. The arms are bent to contact above the clamp body, being fastened together at the point of contact by a short bolt. The arms separate above the short bolt and receive a longer bolt so that a shackle can be inserted through the space between the arms. The body parts are formed with internal conical surfaces tapering to the clamp centre. Two split conical members surround the cable and are forced against the conical surfaces by abutment members screwed into the body.

Title: Improvements in or relating to oscillatory systems suitable for use for wireless signalling and similar purposes
IPC: H03B5/34
Filed: 1933-03-09
Abstract: 407,529. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.- (Assignees of Whitaker, J. N. ; 95, Highland Avenue, Tuckahoe, New York, U.S.A.) March 9, 1933, No. 7209. Convention date, March 19, 1932. [Class 40 (v).] A four-electrode valve 8, Fig. 1, has the grid 16 maintained at a higher potential than the anode 22, so that the valve has a negative resistance characteristic and generates oscillations in the tuned circuit 24, the frequency of oscillation being stabilized by an oscillatory system, such as a piezo-electric crystal 2, connected between the grid 4 and cathode 6. The frequencies of the circuits 18, 24 are preferably successively higher or lower harmonics of the crystal 2, thus obtaining high frequencies without using separate frequency multipliers. Oscillations may also be generated in the circuit 18 as the result of coupling between the anode 22 and grid 16 which may be augmented by a condenser. The oscillations in circuit 24 may be modulated by a valve 36 whose plate current varies the potential applied to the anode 22 and is controlled by a key 38. In a modification, a tuned circuit 42, Fig. 2, is connected between the two grids 16, 4, the anode circuit 24 being tuned to an harmonic of the circuit 42. The valve 52 varies the potential applied to the anode of valve 8 by varying the current through the choke 50 in accordance with voice potentials from a microphone 53. In a further modification, a piezoelectric crystal is connected between the control grids of two valves in push-pull, both operating with negative resistance characteristics, and having tuned circuits connecting their screen grids and also their anodes (Fig. 3, not shown). The piezo-electric crystal 2 may be replaced by a tuning fork, a tuned circuit, or a generator. According to the Specification as open to inspection under Sect. 91, a pentode valve 8, Fig. 2 (Cancelled), generates oscillations as a result of feed back between the grids 16, 4, the grid 40 being maintained at earth potential. The circuits 18, 24 are preferably tuned to successively higher harmonics of the oscillatory system connected between the grid 4 and cathode. This subject-matter does not appear in the Specification as accepted.

A machine for edge-grinding glass plates or the like comprises a supporting member C for firmly holding a template T and a plate or other workpiece P to be edge-ground in a horizontal position and in superposed parallel relationship, a driven wheeled carriage K provided with a vertical shift 10 carrying a feeler disc 15 at the height of the template and a grinding wheel 16 at the height of the workpiece, and means for simultaneously driving the vertical shaft and wheeled carriage to urge the carriage with its feeler disc against the template while being driven around the template and workpiece. The supporting member has a number of columns C on a bedplate 1, each column having a cavity 2 on its upper surface which is surrounded by a supporting and packing ring 3 and connected by a hose 5 to a vacuum pump to hold the template, such as a previously ground workpiece, on the upper surface of the column. A plurality of rings 6 are disposed above the template and each ring is provided with rings 7, 8 in its plane surface and connected by a hose 9 to the vacuum pump so as to hold the workpiece securely above the template. The shaft 10 is mounted in a column 11 on the carriage K and at its upper end rotatably carries the feeler disc 15 and fixedly carries the grinding wheel 16 which has a contour complementary to that to be ground on the workpiece. The shaft 10 is driven by a belt 29 and pulleys 14, 24 from a motor 22 which also drives by way of pulleys 23, 26 and belt 25 a reduction gear 27 connected by a chain drive 28 to a driving wheel 19. The carriage is also supported by a pair of castor wheels 20, 21 having conical profiles. Wheel 20 is carried by a pivot 120 freely rotatable about a vertical axis and wheel 21 is resiliently restrained by a spring 34 at right angles to the plane of the driving wheel 19. The pivot 30 of the wheel 21 is mounted in a bearing 230 secured to a shaft 330 vertically slidable in the carriage and having its upper end connected by a fork 130 and bell-crank lever 32 to a threaded spindle whereby the vertical height of the carriage, and hence the disc 15 and grinding wheel 16 are adjusted. In operation, a workpiece and template are mounted on the columns C and the carriage is positioned with the feeler disc adjacent the template and the workpiece engaging the grinding wheel. When the motor is started to revolve the grinding wheel, the carriage is driven around the workpiece and the grinding wheel and feeler disc are pressed against the workpiece and template.

Abstract: 764,815. Cold separation of gas mixtures. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 17, 1955 [March 19, 1954], No. 7812/55. Class 8(2) [Also in Group XIII] The Specification describes two applications of a reversed hot gas engine to gas condensing or fractionating apparatus. As shown in Fig. 2, a gas, e.g. air, fractionating column 30 has a boiler 37 for the fraction of higher boiling point, heat being supplied to the boiler by a pipe 36 through which flows the incoming gaseous mixture which has been pre-cooled in a heat exchanger 34 by the fraction of lower boiling point. If the heat supplied by pipe 36 is insufficient, part of the liquid oxygen is withdrawn through pipe 42 by a pump 43 and takes up heat in a heat exchanger 27 from part of the reversed hot gas engine 31 (see Group XIII) the freezer of which forms the cold source of the column. The warmed oxygen is then returned to the boiler 37 through pipe 44. As shown in Fig. 3, gas to be condensed on the freezer 70 of a reversed hot gas engine (see Group XIII) is pre-cooled by two heat exchangers 73, 72 arranged in series, the gas flowing upwardly. Liquefied gas is withdrawn through a trap 80.
