Title: Improvements in or relating to clamps for spacing devices for overhead electrical conductors
Inventor: TORR RALPH PERCIVAL
IPC: H02G7/12
Filed: 1961-07-06
Abstract: 929,693. Supporting cables. ANDRE RUBBER CO. Ltd. Feb. 9, 1962 [July 6, 1961], No. 24473/61. Class 36. A spacer for overhead transmission lines has a resiliently bushed clamp through which the line passes the bore of the clamp being flared outwardly to accommodate the internal surface of a similarly shaped bush. Fig. 1 shows the clamp which comprises two parts liquid together at 3 and provided with a locking pin 19 and cutter. The two jaws are forced together against the resilience of the bush 5 on the cable and the cotter inserted in recess 22. Fig. 3 shows the cross-section of the bush and clamp. The bore walls are concave at H and engage concave outer surfaces of the bush. The ends of the bush are also curved at 11 on e smaller radius of curvature than an adjacent part 10 of the bore. This allows the bush to give if the cable is not accurately aligned with the cable axis. The bore of the bush may be the same as that of the cable in which case the external diameter of the bush is greater than the bore so as to ensure that the cable is gripped. Alterna tively the bore of the bush may be equal to that of the cable in which case the outside diameter is equal to the bore of the clamp. The bush may be formed in two semicircular halves each of which is provided with a locating pin for engaging the appropriate part of the clamp and may be of synthetic rubber incorporating layers of textile or wire reinforcement. The bore of the bush may be grooved to fit the cable stranding or may be serrated or knurled.

Abstract: 976,823. Drying apparatus. FAN SYSTEMS Ltd. June 20, 1963 [June 27, 1962], No. 24595/62. Heading F4G. [Also in Division B7] A vehicle for traversing backwards and forwards along a fixed track and carrying working apparatus, e.g. a fan and drier units for drying stacks of unburnt bricks as in Specification 887,771, is suspended from the track 1 by rollers 2 which are attached to side plates 5 of the vehicle frame and are adjustable in vertical position. The side plates 5 are connected by V bars 6 and carry angle bars 10 to which are connected plates 11 which support positioning rollers 12 which are adjustable in a transverse direction by means of nuts 11a. The working apparatus 28, 30, 31, 32 is supported by a pair of angles 13 connected to the plates 5 which also carry a vertically disposed pair of angles 14 between which are connected plates 15 which provide pivot supports 16 for extension arms 17a of the base plate 17 of a motor 18 which is geared to a driving roller 19. The roller 19 is urged into contact with a driving track 20, supported from the track 1, by a pair of springs 21 which act between a pair of angles 22 extending from the angles 14 and a web 23 carried by the base plate 17. At the ends of the travel of the vehicle it encounters a resilient stop checking its motion during the course of which check the driving roller 19 rides off the track 1 and by virtue of the action of the springs 21 and rebound of the vehicle from the stop, the roller 19 re-engages with the track 20 only on the opposite side whereby the vehicle resumes its travel in the opposite direction. The motor may be pivoted to one side, e.g. for repairs, against the action of the springs 21, and held in the displaced position by a latch member 25 which normally hangs in an inoperative position. The angles 22 are connected by a member 24 to which through connections 3, 4, towed vehicles may be attached.

Title: Improvements in or relating to thermionic valve circuits
IPC: H03K4/43
Filed: 1938-08-23
Abstract: 518,378. Valve generating circuits. WHITE, E. L. C. Aug. 23, 1938, No. 24745. [Class 40 (v)] In a saw-tooth oscillation generator comprising a relaxation condenser 8 charged through a resistance 5 and discharged through a valve 4 under the control of impulses applied at 1, and wherein the load circuit (e.g. the deflecting coils 19 of a cathode-ray tube) is fed through an amplifying valve 9 and transformer 11, distortion introduced by the latter is corrected by negative feed-back derived from a resistance 17 in the secondary circuit of the transformer: In order to enable a small resistance to be employed, the feed-back potentials may be amplified by an arrangement comprising a linear amplifier 22 and cathode-follower 29. In an alternative arrangement, Fig. 2 (not shown) in which an amplifier is interposed between the valves 4 and 9, the cathode-follower is omitted, and the feed-back potentials are applied to the cathode of the interposed amplifier which is thus caused to amplify the difference between the input and the feed-back potentials.

Title: Improvements in automatic balances
IPC: B65B1/32
Filed: 1923-10-05
Abstract: 205,099. Nordling, P. A. Feb. 13, 1923, [Convention date]. Automatic-feed weighers.-The catch mechanism of the feed gate comprises a member connected with the last-closing feed gate, and a pivoted catch engaging the member so as to hold the feed gate in open position, the catch being released by a lever under the influence of a weight or spring, the lever being arranged to bear on the weigh-beam until immediately after the release of the feed gate when the lever is supported by a stop. The bag is fastened to a ring 18, Fig. 2, pivoted on one end of the weigh-beam and surrounding the lower end of a feed shoot 22 provided at the bottom with pivoted feed gates. The main feed gate 29 is retained in the open position by a catch 106 engaging a sliding bar 102 coupled to the feed gate by a link 101. As the bag ring 18 descends a slotted link 113 and a weighted lever 109 follow it and finally displace the catch 106 and allow the feed gate to close under spring action. An adjustable abutment 119 arrests the lever 109 so that the slot 114 leaves the bag ring free of the link 113. A similar mechanism is applied to the last-closing feed gate 35 varied (1) by the addition of a bell which is sounded upon the descent of the bar 102, and (2) by mounting the abutment 119 on a pivoted lever operated by the bar 102 so as to swing back the lever 109 and leave the weigh-beam free of the releasing devices when in the position of equilibrium. Violent movement of the weigh-beam is prevented by a counterweighted piston brake which is inoperative at the balance point. The feed gates are re-opened by hand. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification wherein three feed gates 26, 29, 34, Fig. 3, (Cancelled) are used. The feed gates are held in the open position shown, by catches 41, 42, 47 which are displaced in succession, during the filling of the bag and the consequent descent of the ring 18, by levers 55, 56, 57 pivoted on the stationary feed shoot 22 and engaged within recesses in the ring 18. The feed gates close under spring action, the final feed gate 34 closing an orifice in the first feed gate 26. The size of the orifice may he adjusted by a pivoted plate. The recess for the lever 57 used for liberating the final feed gate is located in alignment with the knife-edges supporting the ring 18 to avoid inaccurate release due to swinging of the ring. The feed gates may be re-opened by turning a handle 70 connected to a gate-actuating arm 71. Ensuring constant length of suspended material at cut-off. The intermediate feed-gate 29, Fig. 19, carries an arm 305. When the feed-gate closes, the arm temporarily engages a pin 306 upon a pivoted plate 301 and swings the plate across the bag ring 18 into engagement with a catch 303 so as to collect the material which passes through the final feed gate. The final feed gate, in closing liberates the catch, and the collected material drops into the bag. This subject-matter does not appear in the Specification as accepted.

Abstract: 656,542. Tape dispensers. KRUEGER, T. H. Aug. 21, 1946, No. 24958. Convention date, Aug. 21, 1945. [Class 18] A tape dispenser comprises a casing formed of two halves 20, 22 hinged together at their base, and enclosing a supply of porous sensitive adhesive tape 40 adapted to be withdrawn through an opening 100 in the top of the casing. A guide plate 58 may be withdrawn with the tape to measure a length of tape or the plate may be fixed to the top of the casing; in either case a cutting edge 107 is provided along the top edge of the plate to sever the tape. The casing is substantially heavy to overcome the resistance of the tape being withdrawn from its roll 40 which is supported on a spindle 36 in one half 20 of the casing. A roller 44 engages the adhesive side of the tape and is provided with spring braking means to prevent the end of the tape from being withdrawn into the casing. The tape extends out of the casing with the non- adhesive side against the plate 58 which is formed as a flange on a bracket 56. The bracket 56 is slidably supported within the casing and has a ledge 70 which engages a pin 74 positioned on a hole 76 or 78, in the side wall of the casing, or it engages the side wall of the casing to limit the extent of withdrawal when the tape and guide plate 58 are withdrawn. After releasing the guide plate 58, which returns to its initial position under gravity or under the action of a spring 90, the length of tape can be readily severed on the edge 107. Specification 656,597, is referred to.

Title: Improvements in control devices for hydraulic actuators
IPC: F15B13/04
Filed: 1958-08-11
Abstract: 828,597. Fluid actuation of switches. GRATZMULLER, J. L. Aug. 11, 1958 [Aug. 12, 1957], No. 25683/58. Class 38 (5). [Also in Group XXIX] An hydraulic system for operating an electric circuit-breaker provides that the opening and closing movements, once initiated, are completed without fail and that the circuit-breaker is thereafter held in position until the next actuation. A single-acting jack (not shown) for operating the circuit-breaker is connected to a line 3 which communicates through a restrictor R with an intermediate chamber 35 communicating with an accumulator 1 through a normally closed valve 6. On depressing a button 17, the ball valve 20 is unseated, and liquid from the accumulator 1 passes through a passage 29, chamber 31, passage 33, chamber 21, past the valve 20 and a non-return valve 22 to a chamber 14, depressing a piston 10 which seats a valve 8 and through an extension 9 unseats valve 6 so that liquid is supplied to the jack through valve 6 and restrictor R. While valve 8 is closing, a restrictor 13 prevents substantial by-passing of liquid en route for chamber 14 to the intermediate chamber 35 so that rapid closure of valve 8 and opening of valve 6 is effected. When button 17 is released the ball 20 re-seats, and the pressures in chambers 14, 35 are equalized via restrictor 13. This pressure, due to the presence of restrictor R, is sufficient to hold valve 8 closed, however low the pressure in service line 3 may be. Restrictor R preferably produces a pressure drop equal to that across valve 6 when fully open. When the stroke of the actuator has been completed valve 6 stays open until a button 15 is depressed to unseat a valve 16 to open chamber 14 to a reservoir 4 via a passage 18. Restrictor 13 momentarily delays release of pressure in the intermediate chamber 35, thus assisting the opening of valve 8 and closing the valve 6. The actuator is exhausted through restrictors R, r in parallel, chamber 35, valve 8 and a passage 11. When button 15 is released to close valve 16, valve 8 continues to be held open by spring since the pressures on the opposite sides of piston 10 are equalized at the exhaust pressure. The accumulator is recharged by a pump 5 when its pressure falls below a predetermined value.
