Patent GB-1513872-A (GB)
Title: Signal processing apparatus
IPC: H03H9/25
Filed: 1975-05-08
Abstract: 1513872 Surface wave multiplexing devices SPERRY RAND CORP 8 May 1975 [8 May 1974] 19441/75 Headings H3U and H4M Surface waves from a broad-band transducer 26a are demultiplexed by stepped multiple-strip coupler (m.s.c.) arrangements 71 into a plurality of narrow-band components. The steps are of such a size that each stepped m.s.c. separates the incoming wave into two sets of frequencies, each set being emitted from a respective side of the step. In a multiplexing-demultiplexing arrangement, Fig. 6, waves from transducer 26a impinge directly (waves 88) or indirectly (waves 89) via a track changer 85, 86, 87 upon an m.s.c. 76. The left and right output tracks 95, 96 of m.s.c. 76 each contain frequency bands separated by where V s  is the wave velocity, the bands in track 95 being shifted from those in track 96 by half the band separation (Figs. 9, 10, not shown). Further band separation then occurs in stepped m.s.c. 77, which constitutes a beam expander, and in stepped m.s.c.s 97, 98, 99 which direct waves in single frequency bands towards corresponding narrowband transducers 60a-h. A similar arrangement is provided on the other side of line 51 or alternatively the wave in track 96 may be absorbed. In a controllable filter arrangement, Fig. 14, signals pass via broad-band input transducer 26a, demultiplexer 71, 71a, externally controlled switch or variable attenuator elements 120, multiplexer 71b, 71c and broad-band output transducer 72a. Elements 120 are positioned in individual data channels and may be actuated to selectively block or pass signals so as to obtain, for example, a filter with variable centre frequency or variable band width. Derived characteristics may be obtained by varying the number and individual bandwidths of the channels, adjacent ones of which may overlap. Elements 120 may be constituted by a surface wave amplifier acting as an attenuator controlled by signals applied to terminals 121, 122. Alternatively they may take the form of transducers (135, 136, Fig. 16, not shown) acoustically isolated by a layer (140) and selectively electrically interconnected by a semiconductor switch (137).

Filed: 1953-07-14
Abstract: 731,497. Drafting mechanism. VEREINIGTE KUGELLAGERFABRIKEN AKT.-GES. July 14, 1953 [July 16, 1952], No. 19559/53. Class 120(2). Drafting mechanism has a carrier arm arranged above the top weighting rollers and is characterised in that a gaseous or liquid pressure transmitting agent such as air or oil is used for loading the top rollers and is fed, for this purpose, into an elastically deformable container located between the carrier arm and the top rollers. As shown the carrier arm 20 which is of U-shape in cross section and open at the bottom encloses on its three sides an elastic tube 25 containing the pressure agent. At its underside the tube 25 acts against roller holding elements 12 through pressure plates 30 which are hinged to holding pieces 23 adjustably mounted on the arm 20. A sheet metal protective cover 29 may be fitted to the underside of the arm 20. The pressure agent is supplied through pipe 40 from a compressor or an oil pump or from a tank containing the agent under pressure or adjustably mounted above the mechanism. In a second embodiment the tube 25 is totally enclosed and an adjustable plunger is used for varying the pressure in the tube and hence the loading on the rollers.
Patent GB-195815-A (GB)
IPC: B63B35/04
Abstract: 195,815. Pernot, F. E. Feb. 3, 1922. Cable ships.-In the laying or picking up of submarine cables an endless band or the like conveys the cable to or from the storage tanks and maintains the proper control of the tension in the cable. The invention is particularly applicable to cables with lumped loading or the like. In the preferred form the conveyer consists of an articulated chain 5, Fig. 1, carrying clamping devices 6 and passing round sprockets 7, 8 the latter being equipped with brake gear. As shown in Figs. 2 and 4 the clamps comprise a number of intermeshing jaws 21 joined to the linkframes 17 by pivoted arms 22 so that the jaws always remain parallel. To ensure that the jaws mesh in the proper manner, their motions are equalized by the gear-segments 24, and the springs 26 close the jaws unless they are held open by the guide rails 28 or the catch 29. The guide-rails force open the jaws before 'the cable leaves the conveyer, and the catch holds them open until they come into position on the cable again as at A, Fig. 1, when the catch is released by a stop, which is withdrawn when a lump appears. The mechanism 12 is provided to hold the cable in position to be engaged by the clamps on the conveyer or to hold the cable firmly in the case of a mishap. As shown 'n Figs. 5 and 7 the guiding and holding device comprises intermeshing V-shaped guides 33, 33<1> which, when open, allow sufficient room for the passage of a lump, and, when closed, can cause the cable 1 to take a zig-zag path, thus controlling its passage. To ensure equal movement of the jaws two racks 35, 35<1> are attached to the respective jaw slides 37, 37<1> and engage opposite sides of a toothed pinion 36. To make it impossible for the jaws to remain closed before an oncoming lump a bell-crank and lever-arm is arranged to contact with such a lump, thus actuating the valve controlling the steam cylinders 41, 41<1> to cause the jaws to open. A similar device may close the jaws after the lump has passed. According to a modification, the lumps may be stored outside the tank and lifted up to the tube by means other than the outgoing cable or the lump passes outside the tube and is lowered over the stern by a crane and winch.

Title: An arrangement for the adjustment of magnetically focussed electron beams
IPC: H01J29/54
Filed: 1953-07-17
Abstract: 776,648. Travelling wave tubes. STANDARD TELEPHONES & CABLES, Ltd. July 17, 1953 [Oct. 25, 1952], No. 19878/53. Class 39(1). A mounting unit for an electron beam tube, preferably a travelling wave tube, comprises in a unitary assembly magnetic focusing means such as solenoids for setting up an axial magnetic field waveguide coupling and matching means extending in a transverse direction and a magnetic shield at one end of the system comprising a transverse disc provided with adjusting means such as a set of mounting screws to adjust the tilt and/or the axial position thereof. The tube is inserted in this assembly so that its gun, which produces a convergent beam, is shielded by the magnetic disc which is disposed at the point of minimum beam cross section so that due to the disc adjustments the beam enters the magnetic field at the optimum point and is correctly centred on entry into the magnetic field. The disc 10 is adjusted by screws 11 acting through springs 14 and may have a tapered inner edge as shown to make the transition region at the edge of the magnetic field as short as possible. In a modification, Fig. 2 (not shown) the solenoids 5, 6 are surrounded by an iron casing which also mounts the disc 10 by means of centering screws. Screws for imparting axial or tilting movement to the disc 10 are mounted in an end flange of casing 8 and have radial biasing springs. The gun is surrounded by a magnetic screen 2, Fig. 1, and the gun anode is continued by a non- magnetic sleeve 3 connected to helix 4. Disc 10 also serves to keep stray magnetic fields of the focusing coils away from the gun. Prior arc arrangements are referred to of the type in which there is a magnetic disc shielding the gun and the beam is centred before entering the magnetic field by an auxiliary tiltable coil or by two pairs of coils. This arrangement has the disadvantage that stray magnetic fields of the coil or coils distort the cross-section of the beam.

Title: Improvements relating to the destructive hydrogenation of carbonaceous materials
IPC: C10G1/06
Filed: 1929-06-28
Abstract: Acid residues from the refining of crude hydrocarbons with acids, such as concentrated sulphuric acids, or those resulting from the treatment with condensing agents, for example, the solid products arising from the condensation of middle to lubricating oils by the action of olefines in the presence of aluminium, zinc or ferric chloride, are converted to more valuable products by first treating with a desulphurizing or neutralizing agent, such as Florida earth, iron oxide or quicklime, and then subjecting to destructive hydrogenation under pressure, with or without catalysts.  Other carbonaceous material, such as a tar oil, may be added or the acid residue may be made into a paste with coal. Pressures from 5 to 1000 atmospheres may be employed and the temperature may vary from 300 DEG to 700 DEG  C.  Catalysts, when used, should be those immune from poisoning by sulphur, such as compounds of the metals of the sixth group, for example, oxides of molybdenum, tungsten, chromium, or cobalt sulphide.  In an example, the solid residue from the treatment of a middle oil with olefines in the presence of aluminium chloride, as described in Specification 299,086, [Class 91, Oils &c.], is neutralized with powdered limestone and treated with hydrogen at 425 DEG  C. and 200 atmospheres.  In a second example, a mixture, consisting of equal parts of a residue from the refining of a benzine with concentrated sulphuric acid, and a residue derived by the treatment with alkali of an acid refined oil, is treated with 2 per cent of ferric oxide and 3 per cent of burnt lime and destructively hydrogenated at 208 atmospheres and 425 DEG  to 455 DEG  C.

Title: Improvements relating to split-phase electric motors
Inventor: SMITH BERNARD GEORGES
IPC: H02P23/00
Filed: 1958-06-23
Abstract: 849,299. Control of A.C. motors; thermal switches. GENERAL MOTORS, FRANCE. Feb. 11, 1959 [June 23, 1958], No. 19983/58. Classes 38 (3) and 38 (5). Apparatus for continuously reversing a splitphase motor comprises switches K1, K2, K3, provided with normally-engaged contacts 54- 60, 56-84, and 58-62, respectively. When power is switched-on, current passes through switches K1, K3, and the running windings P1, P2, of the motor, a heater coil R1 being energized through the switch K3. At the same time, the starting winding S of the motor is supplied with current through the switch K2. After a predetermined interval, the heater coil R1 causes movement of the bimetallic strip 16 which carries with it an insulation strip 20 and spring abutments 22, 24, 26. Switch K1 is operated at first, under pressure from a toggle spring 32, so that a blade 42 moves to a position in which contact 54 engages contact 66 to break the motor-circuit. The motor comes to rest and a centrifugal switch C closes. The heater R1 remains energized, however, so causing further movement of the strip 16 until switch K2 is operated by a toggle spring 34 which forces a blade 44 to shift to a position in which contact 56 engages contact 86. The heater coil R1 continues to be energized, and further movement of the strip 16 ultimately operates the switch K3, whereupon a blade 46 is moved by toggle spring 36 to engage contacts 58, 68. Under these conditions, the motor re-starts in the reverse direction, and, when a pro-determined speed is reached, the centrifugal switch C disconnects the starting winding. A heater coil R2 is now energized, and this causes a bimetallic strip 18 to move in a direction opposite to the previous movement of the strip 16. Switch K1 operates eventually to disconnect the motor, leaving the heater R2 energized. Subsequently, the switch K2 reverses the connection of the starting winding, and, finally, the switch K3 re-connects the motor to the supply for rotation in the original direction.
