Title: Improvements relating to railway car retarders
IPC: B61K7/04
Filed: 1963-02-13
Abstract: 1,029,754. Track brakes for rail vehicles. WESTINGHOUSE AIR BRAKE CO. Feb. 13, 1963 [Feb. 20, 1962], No. 5776/63. Heading F2E. Means for retarding a rail vehicle of the kind which produces a braking force proportional to the weight of the vehicle, comprises brake beams 61 disposed on opposite sides of a track rail 10 which is vertically movable, and pairs of levers 30, 32 connected to the rail, the levers of each pair being staggered and extending in opposite directions from the rail to fulcrum on bearers 60 secured to fixed tie bars 20, and each lever comprising an upright arm carrying the respective beam 61, a horizontal arm 36, and a support member 48 which is threaded through hollow interior 38 of the arm 36, one end of member 48 engaging the opposite side of the base of rail 10 and the other end adjustably abutting the end of arm 36 so that the spacing of the beams 61 can be varied. Each arm 36 is provided with three legs 56, 57, 58, leg 56 normally resting on a plate 52 so that the rail is supported in a lowered position, and one of the legs 57, 58 providing the fulcrum on bearer 60, the outermost fulcrum being used for maximum braking and the inner one 57 being used where less braking is required, i.e. at the first and last braking positions along the length of the beams 61. When a vehicle wheel enters between flared ends of the beams 61, the latter are forced apart and through the levers 30, 32 raise the rail 10 so that it reacts according to the weight of the vehicle to determine braking force. The adjustable abutment of the members 48 against the ends of the arms 36 is through a nut adjustable on a threaded outer end portion of each member 48. Rotation of members 48 in the arms 36 is prevented by forming the ends of the member and arm adjacent the rail 10 of square section, the arms 36 being of open slotted section at this end so that the base of rail 10 rests on the members 48. In a modification. Fig. 8, levers 63, 64 are arranged in alignment and have enlarged ends which carry the beams 76, 78 and are provided with guide surfaces 74 for receiving co-operating milled faces 72c of oyelet portions 72b of support members 72, so that the latter are prevented from moving vertically relative to the levers. Pins 70 are passed through the eyelet portions 72b and are received in aligned apertures in pairs of lugs 65a, 65b projecting outwardly from clamp plates bolted to the web of rail 10. The modified apparatus is otherwise similar to that described above.

Title: Improvements in and relating to signalling apparatus for use in mine shafts
IPC: B66B19/06
Filed: 1920-02-26
Abstract: 162,850. Blunt, R., and Mitchell, H. F. Feb. 26, 1920. Mine signalling systems; order apparatus.-In apparatus of the stepwise-indicator type, the indications are arranged on vertical ladders n which have rungs m engaged by pawls p actuated by electromagnets a. Separate ladders are provided for the men, destination, operating, and, where necessary, change-deck signals. The signals are given by closing a switch the required number of times, and separate switches are provided for the men and change-deck signals, but one switch in common for the destination and operating signals. Each of the pawl-carrying levers j in its rise contacts with a wire 8 to close a circuit and ring the bell 7. The ladders are retained in position by pawls r pivoted on horizontal rods s and resting on rods t. The " operating " ladder is marked with numbers 1 to 5 only, but is operated by the same switch as the destination ladder which is marked with numbers from 6 upwards. When a destination signal is given, the " operating " ladder at the sixth step trips a lever 3 and closes a switch consisting of a forked wire 5 dipping into cups 4 of mercury on circuit of the destination ladder. Subsequently closures of the same switch raise the destination ladder only. The switch is of the type described in Specification 161,806, which combines with the main switch a secondary switch. On an operation signal being given after a destination signal, a circuit through the solenoid e is first closed by the secondarv switch and by means of mechanism w the pawl r is tripped to allow the operation ladder to return to zero. The circuit through the solenoid a of the operation ladder is then closed by the main switch to raise the ladder one step. When the winding engine is operated to respond to a signal, the circuit through another solenoid is closed to move the rod t, trip all pawls r, and return all ladders to zero.

Abstract: 888,080. Gas-turbine jet-propulsion engines. ROLLS-ROYCE Ltd. Jan. 16, 1961 [Feb. 20, 1960], No. 6049/60. Class 110 (3). A by-pass gas-turbine engine has the outer wall of the by-pass duct formed, in a transverse section, over a major part of its length by a pair of outwardly-convex arcs joined endto-end, each arc being greater than a semicircle in extent so that the transverse dimension of the engine is reduced in the axial plane where the two arcs join. The invention is described with reference to a by-pass compound gasturbine engine in which air compressed in a low pressure compressor is divided, part flows direct to the propulsion nozzle through a by-pass duct and the remainder is further compressed by a high-pressure compressor and supplied to a combustion chamber feeding two separate turbines, one of which drives the highpressure compressor and the other drives the low-pressure compressor. The turbines exhaust to the propulsion nozzle. The by-pass duct 13, Fig. 2, has an outer wall 26 formed along part of its length by a pair of outwardly-convex arcuate portions 26a which are joined together in the vertical plane. At the intersection of the two arcuate portions, radial walls 27 which are connected to the inner circular wall 28 of the by-pass duct, are provided. The walls 27 have a number of apertures 29 which equalize the gas pressures in the arcuate portions 26a, and the topmost wall is connected to the strut 24 by means of which the engine is supported from the aircraft wing. This arrangement of the by-pass duct allows a larger engine to be installed in an existing aircraft without affecting the ground clearance and the clearance between the engine and the aircraft wing. A modification in which the engines are mounted on the side of the fuselage is also described. Specifications 843,359 and 852,829 are referred to.

Title: Positioning device using negative spring-rate tensioning means
IPC: G01D11/18
Filed: 1973-02-09
Abstract: 1383476 Electric meters; recording apparatus FOXBORO CO 9 Feb 1973 [31 March 1972]  6390/73 Headings G1Q and G1J [Also in Division F2]  An apparatus for positioning a member 76 includes an element 70 which changes dimensionally with temperature and a spring assembly 82, 90 which opposes any temperature-induced changes in the member 76 and whose opposing force reduces as the change increases. In a device for positioning a pen-recorder stylus the wire 70 contracts when heated inductively by a coil (80) Fig. 7 (not shown). The frequency of the coil signal is a function of the input voltage Fig. 11 (not shown). As the wire 70 contracts, member 76 is rotated about a flexible support 78 fixed to the recorder housing. Leaf spring 82 is fixed at one end 88 to the recorder housing and at the other places a strut 90 in compression. Strut 90 bears against member 76 at 92 and opposes the member 76 rotation. As the member 76 rotates, the angle it forms with strut 90 decreases and the opposing force thus decreases also. The rotation is coupled by pivot 102 and linkages 96-100 to a flexible support 104 on the housing. A spindle (110), Fig. 7 (not shown), is aligned with support 104 and connected to linkage 100. Rotation of the member 76 thus rotates the spindle (110) causing the pen-recorder stylus to be correctly positioned. If the stylus is subjected to external force e.g. by end-stops or operator error, spring 106 absorbs the energy, protecting the wire 70 from excessive stress. In the coil driver circuit, Fig. 11 (not shown), a differential amplifier has inputs from a potentiometer driven by member 76 and the input voltage. The amplifier output charges a capacitor which provides the bias voltage to transistor oscillator, thereby determining its frequency. The oscillator output drives the heating coil, until the two amplifier inputs are equal.

Filed: 1975-02-14
Abstract: 1506641 Making electrical leads SHIN MEIWA INDUSTRY CO Ltd 14 Feb 1975 [20 Feb 1974 18 Sept 1974] 6469/75 Headings B3A and B3W [Also in Division H2] Apparatus for cutting insulated wire into predetermined lengths and presenting one end of each length to a processing station comprises cutting means 3, including wire cutters actuated in intervals between wire feed steps of said predetermined length and insulation cutters downstream of the wire cutters and also acting between feed steps, and transfer means 6, which includes grippers 7 for moving cut lengths 32 transversely of the initial feed direction, the transfer means being displaceable in said feed direction when a gripper is holding a length 32 to strip the cut insulation from the length 32 whereafter the grippers are moved in steps equal to the distance between adjacent grippers, the transfer means being returned for the next gripper to grip the next cut length 32. Preferably wires 5 are fed from two reels 2 through the cutter by a movable clamp 4 and the wire cutter has an insulation cutter upstream of it also. The jaws 19, 20 of the gripper adjacent the cutting means are closed on to the wires 5 by a solenoid-operated lever 53, Fig. 9, before the cutters are actuated. Pivoting of the transfer means about a pivot (11), Fig. 13 (not shown), by means of a cylinder (12), Fig. 3 (not shown), removes the insulation from the rear ends of the cut lengths 32. The grippers 7 are mounted on an endless chain 13 intermittently driven, in timed relation to the wire stripping operation via a one-revolution clutch, and moved one step while the transfer means is in its displaced, broken line position, Fig. 3, to position the next gripper to receive the next lengths of wire fed by the clamp 4. The cut lengths 32 are transferred by the grippers 7 to crimping stations 41, 42, one for each wire. An upper limb 59 of a guide 58, Fig. 1, has a hook 59a for holding back the upper length while the lower length moves along lower limb 60 for a terminal 43 to be crimped to it. Opposite each station a gripper is located at a fixed distance from a terminal 43 by a fixed guide (39) and spring-loaded guide (40), Figs. 5 and 6 (not shown). Stopping of the gripper 7 actuates a clamp 69 to hold the lower length aligned with the crimping means. The next gripper feed step moves the wires into a guide 63, the lower wire being held back by a roller (68), Fig. 18 (not shown), while a terminal 43 is crimped to the upper wire length. At the end of the upper run of the chain 13 a pin 51 on a lever 50 opens the gripper 7 to discharge the wire lengths each with a terminal crimped to it, into a pan 52. Instead of, or in addition to, the crimping stations, means for solder plating the stripped wire ends may be provided between two gripper stop positions.
