Title: Improvements in or relating to apparatus for heating billets or other workpieces
IPC: F27D11/06
Filed: 1942-09-25
Abstract: 560,188. Electric heating. BUDD INDUCTION HEATING, INC. Sept. 25, 1942, No. 13531. Convention date, Sept. 19, 1941. [Class 39 (iii)] [Also in Groups XII and XXX] Apparatus for heating workpieces such as bars or billets particularly in electric induction furnaces comprises propelling means for successively engaging and feeding workpieces to the heating- chamber adapted to be automatically disconnected from a source of power upon a pre-determined propelling pressure being reached such pressure preferably also shutting off the heating means. In the furnace shown in Fig. 4, billets 48 of square section are fed by gravity down an inclined shoot 49 in front of a reciprocating pusher 54 by which they are fed on to a plate 58 and then through the refractory lined tunnel 37 surrounded by induction coils 27 into a heat-retaining delivery chamber lined with firebrick walls 103 and provided with a hinge counterweighted gate 111 secured by a catch 113 released by the movement of the billets and caused to re-engage the gate by the action of gravity. The plunger 54 is driven from a motor 64 through gearing and an adjustable crank 55 and connecting rod 63. The connecting rod 63 actuates the plunger 54 as shown in Fig. 9 through a spring 71 enclosed within a recess in the pin 70 which is shorter than the chamber 69 in which it is arranged to allow for sliding movement upon yielding of the spring when a thrust is applied to the billets through a hardened pin 75 on the face of the plunger. In the event of the feeding pressure of the plunger becoming excessive, the pin 70 slides forward and depresses a pin 78A against a spring-pressed strip 77 and operates through a pin 79 a circuit-breaker 80 to give a signal which may be utilized to cut off power from the feeding motor and also to cut off the supply of current to the heating-coils. The supply of billets from the shoot 49 to the plunger is controlled by trigger mechanism actuated by a cam 81, Fig. 7, on the top of the plunger. As the plunger reciprocates the cam engages a roller mounted on an arm secured to shaft 84, which is rotated and operates a trigger 82 secured to the shaft and adapted to engage and release a billet in the shoot. Movement of the trigger also actuates brake mechanism to apply pressure at 94 to the billets in the shoot while the lowest billet is released. The shoot carries a signal device the nature of which is to cut off power from the machine when the supply of billets to the shoot 49 is exhausted. The heating section of the furnace comprises a longitudinal chamber 37, Fig. 10, lined with interlocking firebricks 30 provided with wearing strips 47 against which the billets bear. The chamber is surrounded by sections of induction coils 27 covered by insulating material 31, 32. Laminated flux conducting bars 33 are arranged at the four sides of the chamber. The coils 27 are connected to conductors 124 and are provided with means for the circulation of water therethrough from flow and delivery pipes 129, 134 connected to headers.

Abstract: 712,942. Artificial legs. BLATCHFORD, W. A. D. April 14, 1953 [May 28, 1952], No. 13533/52. Class 81(2) An artifical leg having a pivotal knee joint which may be locked when the leg is upright, comprises a locking member to be retracted into the thigh or projected from the thigh for engaging a cooperating locking member on the shin so that the shin may be locked in any one of two or more depressions relative to the thigh. The shin member 11 is pivoted relative to the thigh member 4 on a bolt 5. A locking catch 1 is mounted on a pivot 2 on the thigh member 4. The shin member 11 carries a member 12 having depressions 13, 14 which the locking catch 1 engages to lock the limb in a straight or partially bent position. More than two depression may be provided. The catch 1 is normally held projecting from the thigh member 4 by a tension spring 6. Retraction of the catch 1 is effected by a pull on the wearer's control cord 8a and, when the knee is fully bent, by a chain 9 to prevent the catch 1 from damaging clothing &c. The leg is locked in a straight position when the catch 1 engages' one depression 13 in the member 12. The leg may then be bent when the catch 1 is retracted by the control cord 8a. As the leg is straightened from a fully bent position, the catch 1 may either be held by the control cord 8a in a retracted position until the leg is fully straightened or be 'released to engage with the depression 14 and 'lock the leg in a partially bent position, further straightening of the leg causing the catch 1 to ride over a cam surface 15a joining the two depressions 13, 14 until it engages with the depression 13 in straight position. A check cord 15 connecting the thigh and shin members 4, 11 at the rear prevents hyperextension of the leg.

Title: Improvements in directional reception and transmission in wireless telegraphy
IPC: H01Q21/08
Filed: 1924-06-05
Abstract: 217,238. Latour, M. June 5, 1923, [Convention date]. Directive signalling; relaying systems; thermionic modulating systems; aerials.-Relates to directive systems in which a number of frame or other receiving aerials are arranged in line with or across the signal wave-front, and are spaced apart by some uneven multiple of a quarter or half the signal wave-length, and comprises special means for combining the different receptions at a given point in the complex aerial system. For example if the reception on two frame aerials 1, 2 placed half a wave length apart across the wave front, a.s shown in Fig. 1, is transmitted at light velocity to a point 3 midway between the two frames, a flattened curve of reception 5, Fig. 2, is secured in place of the usual curve 4. With an extended aerial system of this character, particularly in populated districts, difficulty arises in combining the various receptions at the collecting point and with the necessary light velocity over a wire conductor. According to the invention, the combination is effected by re-radiating received long-wave signals on a shorter wave-length. As shown in Fig. 5 the original signals received or a frame aerial 11 are amplified by a valve 13, the output of which is then utilized to modulate the emission from a short-wave generator 14 feeding the local aerial.16, for retransmission to the collecting point. This local transmission may be made directional by energizing a series of suitably-spaced aerials such as 16 deposed with regard to time by an amount equivalent to their displacement in space, the necessary control being effected either by a line conductor or by radiated energy. At the collecting point the different modulated short-wave transmissions are detected so as to reproduce the original longwave signal and combined thereby producing the desired directional effect.

Title: Improvements relating to the balancing of reciprocating engines
IPC: F02B75/16
Filed: 1933-05-19
Abstract: 420,155. Balancing moving parts of reciprocating engines. BRAMBLE, W. H., and RUSTON & HORNSBY, Ltd., Sheaf Iron Works, Waterside South, Lincoln. May 19, 1933, No. 14500. [Class 122 (iii)] In balancing reciprocating engines, particularly horizontal, single-acting engines of road rollers and horizontal, internal-combustion engines with double, parallel cylinders and crank-pins in line, additional balancing masses, rotating in opposite directions at crank-shaft speed with or about shafts separate from the main shaft, are provided to eliminate vertical vibrations. A number of smaller masses may be substituted for each individual mass. In the construction shown, power is transmitted to the rear rollers through change speed and reversing - gearing in a box e below the frame f. The shafts i, j are disposed symmetrically about a vertical plane through the crank-shaft. A chain m drives the shaft o at crank-shaft speed. The shafts i, j, geared by wheels k, l, carry weights q, r. Instead of the balance weights rotating in the longitudinal axis of the engine, one or both may be replaced by a pair of weights on either side of the axis. In a modification, wherein the engine drive is transmitted through a chain and toothed gearing not disposed below the crank-shaft, a bracket is disposed beneath the main frame and carries geared, oppositely - rotating, balance - weight shafts driven by a sprocket wheel from the driving-chain. In the above construction, bobweight shafts may be disposed symmetrically about an axis through the crank-shaft. Weights may be arranged on the shaft of the jockey pulley p engaging the chain. The additional masses may be mounted on two or more of the gears of the power transmission gearing. Or metal may be added to, or removed from, the wheels to form the rotating masses.
