Title: Displaceable central couplings for railway vehicles
IPC: B61G5/04
Filed: 1960-04-26
Abstract: 914,577. Transitional coupling arrangements. HILGER, 0., BUSCH, W., and FRIEDERICHS, H., [trading as BERGISCHE STAHL-INDUSTRIE REMSCHEID]. April 26, 1960 [April 27, 1959], No. 14574/60. Class 103(5). A foldable central coupler comprises an automatic head 11 articulated through arms 12 to a transverse bolt 14 mounted in a draw hook 13, and tension spring 20 connected to the forward parts of the arms 12 and pivotally mounted at their other ends on sliders 18 vertically movable in slotted guides 15 abutting the truck. The head 11 is pivoted to a pin 30 in such a manner that it can pivot only upwardly, and the arms 21 connected to the springs are adjustably mounted on the pin. Extensions of the bolt 14 are accommodated in slots 19 of the sliders 18, which sliders are connected together by an upper yoke 22 and a pin 17 slidable in the guide slots 16. Recesses 23a, 23b are provided in the sliders into which a nose 24 of a spring-urged latch may engage, and the guides 15 mount spring-pressed pins 26 provided with rollers 27 which may move over a buffer beam 29. From the Fig. 3 position the head may be raised by pulling the sliders 18 upwardly in the direction R, so as to disengage the latches 24 and cause the bolt 14 and pin 17 to slide relatively to their accommodating slots. The springs 20 assist in raising the head and the latches 24 move into the lower recesses 23a. If the head is moved out of position in the horizontal plane by movement of the bolt 14 about a point M, or by movement of the hook about a point m, the spring 25 on one of the pins 26 is loaded by inward movement of its pin and the spring 25 on the other side is relieved, thus providing a centralising restoring force on the head. In a modification the springs 25 are omitted, and the guides 15 are placed directly in contact with or are fixed to the buffer beam 29, the springs 20 being utilized to re-centre the head. Other forms of automatic latching may also be employed.

Abstract: 612,221. Electric condensers. STANDARD TELEPHONES & CABLES, Ltd., BARNARD, R. M., and WOOLTORTON, E. May 20, 1946, No. 15182. [Class 37] Interleaved electrode and dielectric foils are wound about a former of insulating material forming a condenser unit, and a sheath of metallic foil is placed about the unit, the ends of said foil being metallically bonded to metallised surfaces on said former, thereby providing hermetic end seals and covering for the condenser. In an embodiment, Fig. 1, condenser unit 1 protected by several layers of bakelised paper 6, is wound on ceramic tube 2, having holes 3 housing lead-out wires 4. A single tubular layer of thin, soft tinned, copper foil 7 covers the unit, being soldered along the longitudinal seam and to silvered bands on the tube. The foil is protected by approximately six turns of bakelised paper 8 covering the whole assembly, enabling filling compound to be run into the resulting end cups if required. In a further embodiment, Fig. 2, the tube 7 is replaced by a layer of metal-reinforced synthetic resin bonded paper, hot rolled about the condenser, the metal foil ends being bent inwards to permit of soldering to brass thimbles 14 which are also soldered to silvered bands on ceramic tube 2. Lead-out wires 4 may be chrome iron alloy having approximately the same expansion coefficient as the ceramic, and fastened thereto by glaze, thus enabling direct soldering to the lead without risk of unsealing the container.

Abstract: 1300845 Gas blast circuit breakers BROWN BOVERI & CO Ltd 31 March 1970 [1 April 1969] 15312/70 Heading H1N A gas supply system is arranged to ensure that the pressures in a gas blast circuit breaker are maintained within safe limits. The switchgear comprises high pressure HD and low pressure ND compartments communicating through the blast valve V s , and normally the desired pressures are maintained through reducing valves V 2 , V 1  connected to a buffer vessel P in which the pressure is above the normal working high pressure. This pressure is obtained by a pump K, through filters Fi, drawing gas from the low pressure region ND. However, if the pressure in the region ND falls too low for satisfactory insulation an electromagnetically operated valve V m  closes. Undesirably high pressure in either of regions HD, ND is prevented by safety valves V 3 , V 5  respectively. A similar safety valve V 6  is connected to the storage vessel P, and, additionally, a reserve supply vessel F, connected through a reducing valve V 4  serves to compensate for any gas losses from the system.

As the machine is advanced the cutter bars 4, 5 form cuts extending from the face of the seam at and parallel to the roof and floor of the seam and the cutter chains make vertical cuts interconnecting the first two cuts. The one or the other or both of the cutter bars 4, 5 are moved by pivoting of the associated pair of supporting arms to form a severing kerf between the inner ends of the kerfs at roof and floor level. The cutter bars and chains may be replaced by series of reciprocating picks. The chassis 1 runs on endless tracks 3 and is provided with vertically adjustable endless tracks 2 for engaging the roof and a shield 11. Loading means such as a scoop 9 and loader arms are provided beneath the cutting means for removing disintegrated mineral rearwards.

Title: Improvements in or relating to systems of gunnery fire control
IPC: F41G3/00
Filed: 1937-06-04
Abstract: 496,668. Gun-fire control. JACKSON, L. MELLERSH-. (Schmidt, G.) June 4, 1937, Neo. 15560. [Class 92 (ii)] A method of directing the fire of machine guns using tracer projectiles which are visible to the gunner and to a flank observer includes means for electrically transmitting an impulse from the flank position F, Fig. 2, to the gun position G at the instants when the successive tracer bullets are at the range of the target T, the impulse giving a visual or audible signal to the gunner, who thereupon spots the position of the trace L with respect to the target T and accordingly corrects the aim of the gun by the angle D. Fig. 7 shows one form of apparatus for carrying out the method in which the target is viewed through iris diaphragms 20, 21 by the gunner and flank observer respectively, the impulse being given by closing a switch x in a circuit 23, 24 which includes magnetic means 22 for causing the shutters to flicker. The circuit 23, 24 includes a contact arm 31 which is rotated by a motor 32 moved synchronously with the gun firing mechanism 33 by a contactor switch 29 operated by gearing 40 and situated in the motor circuit 38. The contact arm 31 rotates over a normally stationary insulated ring 301, having a gap contact connected to the circuit 23, 24. The ring 301 can be adjusted by the flank observer by means of a knob 51 to suit the varying times of flight which correspond to the varying range of the target. The impulses will thus be given at times after each tracer has left the gun equal to the time of flight of the tracer to the range of the target. The times of flight can be indicated on a dial 120. Fig. 5 shows three positions of a target T1 T2 T3 with the adjusted intersecting observations at S1 S2 enabling a hit to be effected at T3. The arcs 70, 71 represent the adjustment made by the flank observer to suit the range of the target, the gunner meanwhile correcting the lead for the observed error LP. Instead of the impulse influencing a flickering shutter, a colour screen may be located within or removed from the field of the gunner's sight to give the visual signal.

[Also in Division B8] In a method of manufacturing air cushions for packing fragile objects or for seats &c. two sheets 1, 2 or 1, 2<SP>1</SP> of air-impermeable plastic foil are welded together by electrodes shaped to form at least one row of chambers 5 separated by transverse welds, the adjacent chambers of each row communicating with one another by small unwelded portions 7, the chambers of each row are inflated from a common supply of air under pressure and the chambers are then sealed off by completing the transverse welds. The welded workpiece is laid on a table 12 and clamped by strips 12<SP>1</SP>, abutment strips 15 are moved by means of handwheels 18 to adjust the predetermined height to which the chambers are to be inflated and table 12 is lifted by mechanism 11 until strips 12<SP>1</SP> contact abutments strips 15. Air is supplied through nozzles 18<SP>1</SP> to inflate the chambers and as soon as the chamber furthest from the supply attains the desired height it contacts a feeler 22 which operates an optical or acoustic signal or acts to cut off the air supply.
