Title: Improvements in or relating to means for marshalling rail vehicles such as mine carsor tubs
Inventor: ROUND CHARLES
IPC: B61J3/08
Filed: 1954-01-13
Abstract: 781,461. Rope railways. COAL INDUSTRY (PATENTS), Ltd. April 13, 1955 [Jan. 13, 1954],No. 1008/54. Class 104 (2). Rail vehicles are marshalled by an endless rope or chain arranged along a track or tracks to move a bogie or bogies running or sliding in fixed guides beneath the rail level and carrying pivoted catches to engage and move a vehicle when moved in one direction, the catches being released when moved in the other direction. The catches 19 are pivotally mounted on trolleys 21 having flanged wheels 22 running on members 23 arranged between girders 2 supporting the main rails 1. The lower end of the catches 19, Fig. 5, engages a slot in a link member 24 connected to the endless rope 8 and the arrangement is such that when the rope 8 is moved in one direction the catch 19 abuts one end of the slot in the link 24 to be held in an upright vehicle-engaging position. When the rope 8 is moved in the reverse direction the catch 19 is moved to the inoperative position. A " cut of cars or tubs " is moved by a rearward catch 18 along a section A to a section B and then by catch 19 past a turnout C to a section D from which the " cut of cars returns by gravity through the turnout C to a section E which passes through a loading station F. The track is slightly upwardly inclined from the left to right of Fig. 1. Gravity catches 40 at section B hold the last car of the " cut of cars " to be moved to point D and the first car of the " cut of cars " to be moved by the catch 18 during the uncoupling operation. The rope 8 passes over wheels 9, 10 and is supported along its length by pulleys 7. The rope 8 is kept taut by the wheel 10 which is mounted on a trolley 11 running on a short length of track 12 and held in the outward position by a suspended weight 13. The rope 8 is driven by an electric, compressed air or like reversible motor 16 through a drum 17. Spring-loaded buffers 27 mounted each end of the run between members 23 limit the movement of the catches 18, 19. The head of the buffers 27 is supported on rollers 29 running on the members 23 and is held in the outward position by a compression spring 31. Limit switches 35, 37 are secured to the members 23 at each end of the run. A second limit switch 36 mounted on the members 23 just beyond the limit switch 35 reverses the motor 16. An additional endless rope and catches may be provided to move the cars or tubs away from the loading point F. The chain in this case being driven by a wheel mounted on the same shaft as the wheel 9. A hub guide 5 is supported adjacent the track by posts 6. The turnout rail is formed with a slot 39 where it passes over the member 23 to permit the passage of the catch 19.

Title: Improvements in or relating to fm multiplex stereo transmission reception indicating apparatus
Inventor: KASUGA JIRO
IPC: H04B1/16
Filed: 1963-01-09
Abstract: 1,031,345. Stereophonic radio receivers; tuning indicators. TORIO CO. Ltd. Jan. 9, 1963, No. 1016/63. Headings H3Q and H4L. A radio receiver for stereophonic or monaural reception is provided with an indicator controlled by a pilot signal used in the transmission of the stereophonic signals, to indicate automatically the reception of a stereophonic transmission, which is located adjacent a tuning indicator. As shown, the incoming signals are supplied via a conventional H.F. amplifier, and I.F. amplifier to a limiter 9 followed by a frequency discriminator 10, the output of the discriminator being supplied via an amplifier 11 to a sub-carrier regenerator G, a sideband filter F and a low-pass filter D and the left and right signals being recovered in known manner in a matrix E. Potentiometers 12 ... 15 and 16, 17 are arranged so that in the absence of an incoming signal the valve 3 is cut off. When the receiver is tuned to a signal, the potential at point a is increased and valve 3 operates to amplify a portion of the sub-carrier which is fed from the output of valve 11. The output of the valve 3 is rectified at 5 and operates a magic eye indicator 8. A similar magic eye acts as the tuning indicator. In a simplified arrangement the amplifier controlling the stereo indicator is not cut off in the absence of a signal.

Title: Antenna feed systems
IPC: H01Q21/20
Filed: 1954-01-13
Abstract: 739,618. Aerials. RADIO CORPORATION OF AMERICA. Jan. 13, 1954 [Jan. 30, 1953], No. 1036/54. Class 40 (7). The feed point of an antenna array having a plurality of elements occupying an aperture a plurality of wavelengths long is displaced from the centre of the aperture by more than 5 per cent of the total aperture length and equal amounts of energy are fed to the two groups of elements on the two sides of the feed point. The arrangement may be adjusted so that a vertical aperture gives a substantially cosecant distribution pattern over a desired service area. In one embodiment a slotted cylinder 31 is mounted vertically and the slots 33 are arranged 3 in each of a number of layers with adjacent layers staggered by 60 degrees to ensure uniform illumination in a horizontal plane. The feed to the array is by coaxial feeder 35, 37, led centrally up the lower part of the structure to a point # below the half-way position. At this point the outer conductor is left open and the inner conductor 37 connected to a rod or tube element 39 extending centrally up the cylinder 31 to the top of the system. Thus the feeder 35, 37 is coupled to two coaxial transmission lines 31, 39 and 31, 35 feeding the upper and lower groups of slots respectively. The ends of these lines are each shorted at 43, preferably by a spoke arrangement to allow the antenna to be ventilated. Each slot is coupled to its transmission line by a coupling loop 41 have integrally arranged capacitive or inductive reactance which is adjusted to make the slot appear as a load impedance of a desired magnitude. It is arranged that the impedance presented by all the slots above the feed point taken together is the same as that presented by those below. This causes the upper part of the aerial regarded separately to radiate in a narrower vertical pattern than the lower part although the energy radiated is the same. Partial elimination of nulls results from the combination of the two patterns (Fig. 5, not shown). The elements need not be regularly spaced along the length of the tube providing the aperture length is adequately covered.

Abstract: 553,191. Cathodes heated by electric resistances. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philip's Gloeilampenfabrieken). Jan. 26, 1942, No. 1097. [Class 39 (iii)] [Also in Groups XXII and XL] Relates to indirectly heated cathodes made by arranging a conductor wire within and spaced from a conducting tube, filling the intermediate space with insulating material and shaping this compound body to form a cathode of the desired diameter and consists in bending this cathode into a helix, spiral or other form and coating it with emitting material on a portion only of its surface. One or more conducting wires of nickel, 1 mm. in diameter, may be held by a jig within a copper or nickel tube, 8 mm. in diameter and ¢ mm. thick, while powdered magnesia or alumina is compressed therein. The body is then drawn or rolled or both until the desired flat or other form or the desired size or both are obtained. The cathode may then be coated on one side with barium and strontium carbonate and wound into a helix, e.g. with a substantially cylindrical inner surface coated with the emitting material. The form of such a coiled cathode may correspond with that of the grid. In another modification the cathode may have a ring form and may constitute one of the conductors of an ocsillatory circuit constructed as a "Lecherline" system. Bent cathodes may also be used in the "Kolster" or other oscillating circuit.

Title: Improvements in Repeating or Amplifying Systems, particularly applicable for Telephony.
IPC: H04M3/40
Filed: 1919-01-21
Abstract: 134,444. Western Electric Co., (Western Electric Co.). Jan. 21, 1919. Telephonic repeaters. - Relates to repeating systems, particularly suitable for telephony, in which main and auxiliary signalling currents, for example voice currents and ringing-currents, are repeated from one section of the line to another. In the case of telephony, the filtering-circuits, potentiometers, or other auxiliary means, used to repeat efficiently the voice currents, which are detrimental to the repetition of the ringing-currents, are automatically disconnected during the transmission of the latter. Voice currents from the section 11 of the tine pass through the filtering-circuits 15, 16, potentiometer 17, normal contacts of relay 18 and transformer 19 to the grid circuit of a valve 13, the plate circuit of which is connected through a condenser 23 to the primary of the output transformer 20, the secondary of which is in the line section 12. The condenser 23 is shunted by a relay 21 and condenser 22, forming a circuit tuned to the frequency of the rinsing-current. Ringing- currents from the section 11 at first pass over the same circuits as the voice currents, but after the first few impulses the relay_21 opens the circuit of relay 40, thereby energizing the relay 18, which connects the section 11 direct to the transformer 19, disconnecting the filtering-circuits and the potentiometer. The relay 18 also short-circuits the primary of the output repeating-coil 30 associated with the section 11. The circuits are duplicated for repetition from the section 12 to section 11. Balancing circuits 24, 34 are arranged as shown.

Abstract: 562,324. Enlarging pistons. EVERY, C. E. (Hodgkiss, A.). Jan. 30, 1943, No. 1617. [Class 83 (iv)] Tube - expanders.- Hollow pistons, particularly of aluminium alloy, for motor car engines, are enlarged to fit a rebored cylinder by heat ing to a temperature at which the metal will flow readily under pressure and applying outward radial pressure to cause a limited radial expansion of the wall of the piston. The expanded piston may be quenched in a water or other liquid bath. Expansion may be effected to a slightly greater diameter than is required and the piston then reduced by grinding or turning. Expansion may be effected by a tool consisting of a body 1 slotted to receive a pair of thrust members 2, which are moved radially by the tapered end of the screwed stem 4 of a handle screwing into the. body. A- pair of part cylindrical thrust pads 8 are inserted between the piston and the members 2. The tool and pads are first inserted in the piston and the stem 4 turned to move the thrust pads into contact with the piston wall. A nut 9 is then tightened on the body and secured by a lock nut 10 and heating then effected, whereupon the stem 4 is rotated to effect the expansion. The piston is then quenched and then machined and ground to final dimensions. Thrust pads of different sizes are used for different sized pistons.

Abstract: 1,198,542. Etching. VACCO INDUSTRIES. 11 Jan., 1968, No. 1621/68. Heading B6J. [Also in Divisions B1-B2 and B3] Annular discs for stacked edge filters (Fig. 1, not shown) are made by etching, which simultaneously provides a rough surface between and on lateral sides of upstanding lands, this surface trapping small particles which are able to penetrate between the discs themselves. The inner and outer edges of the discs are also roughened. In Figs. 3 to 6 (not shown), two sides of a metal sheet are coated with etchantresisting lacquer such as vinyl methacrylate except for the outlines of discs, left uncoated on both sides (Figs. 3, 4), and areas corresponding to spaces between circular lands (31). The sheet is then dipped in or sprayed/brushed with etchant, to create the lands and sever the discs from the sheet in one or two steps. The discs have lugs (30) and notches (33) to ensure that they can be assembled in their enclosing cage only one way up (Fig. 2, not shown). The sheet is 0.002 inch thick and the lands (31) extend 0.001 inch above the area therebetween. In Figs. 7 to 12 (not shown), concentric arrays of annular discs of four different sizes are made from one metal sheet. In the first step (Figs. 7, 8) lands in the form of generally but not quite radial ridges are formed on both sides of the sheet and disc outlines are also partly etched away, other areas being protected by lacquer. A thick and continuous lacquer coating (50) is then applied to one side of the sheet and a coating (49), which leaves annular gaps defining the disc outlines, to the other, and the discs are severed from the metal sheet in a second etching step, but remain joined by coating (50) (Figs. 9, 10, 11). A series of such sheets are stacked together, and coatings 50 are all dissolved away in trichlorethylene (Fig. 12), after which a tool (51, 52) is used to withdraw stacks of discs which are placed on mandrels (53) (Fig. 13, not shown) until required.

Abstract: 969,891. Resilient diaphragms. DUNLOP RUBBER CO. Ltd. Jan. 10, 1961 [Jan. 19, 1960; May 14, 1960], Nos. 1819/60 and 17106/60. Heading F2S. In a method of manufacturing a resilient diaphragm of the rolling- lobe type a cord 33 of textile material, e.g. nylon, is wound alternately over axially-aligned notches 31 in end and guide plates 13, 15 on end members 11 urged apart by a spring 24 and mounted coaxially on a central rod 12 of a forming spool 10 to form a cylindrical sock, the end members 11 are twisted relative to each other through a predetermined angle so that they approach each other against the action of the spring 24 and produce a neck in the sock, and the latter is treated, e.g. by dipping into latex or rubber solution, so that it remains in a twisted condition on removal from the spool. In one process a ply of uncured rubber 32 is first applied to the end members 11 so that the cord 33 beds into it when the neck is formed a further ply 34 of cured rubber being added and the plies then being rolled. After rolling the cords 33 are either cut, or unhooked from, the ends 11 and the sock is pulled off the spool 10 one half 35 being fitted over a first former (Fig. 6) and the other half 36 being drawn down over a bead wire 38 the space 39 being filled with a rubber strip and the halves 35, 36 being consolidated by rolling. The member 35, 36 is removed from the former 37 and inserted in a cavity 40 in a second former 41, Fig. 7, the members 35, 36 then being drawn down over a ridge 42 and the free ends folded back over a bead wire 43 and rolled. The space 44 is filled with a strip of rubber and the member 35, 36 is then removed from the former 41 and placed into a mould for curing by heating. The two end members 11 each consist of a pair of end and guide plates 13, 15, cylindrical and tapering members 14, 16 all secured together by screws 18 the lower end member 11 being non- rotatably located by a pin 46 on the lower end of the rod 12 the upper end of which carries a locking mechanism 28, 29 which frictionally engages the surface of a bore 26 in the upper member 11 when a nut 20, engaging the threaded upper end of the rod 12, is tightened. Release of the nut 20 allows the upper end member 11 to rotate the spring 24 urging the members axially apart. The number of cords may be increased to be as close as required at the neck of the sock.
