Abstract: 163,840. Bicknell, T. E. March 11, 1920. Fastenings operated mechanically or pneumatically from a distance; latches, sliding; striking- plates.-A safety-lock for railway-carriage doors is releasable by the guard either by the control of a vacuum pipe, or by a rod or chain running along the train; a connection is also made with the communication cord, and a lever placed outside the carriage door. Fig. 1 shows the general structure of the lock, which is fixed in the framework of the door, the inner cover-plate being secured by screws which are accessible only from the other side of the lock. The latch A is provided with a number of ratchet-shaped teeth, Fig. 6, to engage a striking-plate of a similar formation, so as to provide a multiple catch. The vacuum release-gear consists of a cylinder B having a connection N to a train-pipe, in which a vacuum can be established by means of a twoway valve under the control of the guard. The piston C is thereby drawn into the cylinder, so releasing the latch. The pivoted arm G is connected by a chain passing over a guide-pulley H to the communication cord, so that pulling the latter simultaneously withdraws the latch, which can slide freely upon the piston-rod. The external mechanical control comprises a rod or chain A<1>, Fig. 9, which can be traversed by the movement of a lever placed in the guard's van, or mounted upon the end of each carriage. This movement rocks an arm U secured upon the spindle Q to which the arm G is secured. Direct movement of a lever B' mounted outside the carriage effects a similar operation.

Title: Improvements in or relating to methods and apparatus for butt welding fine metal filaments
Inventor: WAKELEY WILLIAM M
IPC: B23K11/26
Filed: 1959-03-04
Abstract: 918,920. Supply systems for arc welding apparatus. MINNEAPOLIS - HONEYWELL REGULATOR CO. March 4, 1959, No. 7566/59. Class 38 (4). [Also in Group XXII] In butt welding the ends of fine metal filaments, a high electrical voltage is applied to the tips of the filaments while they are spaced apart such that the electrostatic field created between them aligns the ends and the aligned filaments are brought together for welding. Fine wires are inserted into the electrically insulating clamping members, on low potential D.C. source, e.g. a capacitance bank and a highvoltage D.C. source are connected across the clamps. The wires are brought together so that the electrostatic field causes them to move to the shortest distance between them, i.e. align, and they are brought slowly together when a high-voltage discharge occurs; creating an ozone atmosphere about the wires. The wires are moved still closer and a weld is effected by the discharge of the low-voltage source. In an embodiment an A.C. supply 10 across conductors 11, 12 supplies the equipment. Conductors 14, 15 supply a transformer 17 connected to a D.C. network 20. A dry plate rectifier 22 is in series with the transformer secondary and a substantially constant D.C. voltage appears across points 27, 28. A lowvoltage supply is taken via a potentiometer 30 by conductors 37, 38 to charge a bank of condensers 40-46. Conductors 63, 64 connected to conductors 11, 12 energize an autotransformer 65 which supplies a transformer secondary 70 connected to conductor 37 and to plate 73 of a high-voltage rectifier 74. The cathode and heater of the rectifier are connected to a transformer secondary 76 which is connected via a potentiometer to a conductor 82 connected to a clamp 83 for a wire 84. The other wire 85 is held in a clamp 86 connected to the condenser bank. A high-voltage rectifier tube 91 has its plate 92 connected to the conductor 38 and its heater and cathode are connected to the secondary 94 of a transformer which is connected to the conductor 82. The rectifier 91 provides a discharge path for the charged condenser bank and forms a buffer between the high-voltage network and the bank to prevent a high-voltage discharge through the latter.

Filed: 1942-06-04
Abstract: 554,430. Motor-vehicle frames. FORD MOTOR CO., Ltd. (Ford Motor Co.). June 4, 1942, No. 7625. [Class 79 (iv)] [Also in Group XXII] In making a vehicle frame a pair of structural members are first buttwelded together, the parts being moved in a predetermined direction to compensate for the loss of metal due to flashing, then this sub-assembly is buttwelded to other members, the flash compensating movement being in a direction perpendicular to the first direction, and the assembly is then butt welded to other structural members, the flash compensating movement being in a direction perpendicular to both the previous directions. The X-shaped L-section stamped halves 11, 12, of the central rectangular box member are first clamped in the jaws of a welding machine and then butt-welded together, relative movement between the jaws being effected to compensate for flash. The flanges on each half are so shaped that the box structure has openings 13, 14, in the ends and sides thereof, the openings 13 taking the propeller shaft with clearance in any dosition. Pairs of front and rear diagonal channel members 15, 16 provided with circular flanges 17 welded to cross-members 18, 19 to form triangular sub-assemblies are then butt-welded to the channel shaped corners of the box members, the flash compensating movement being in a direction at right angles to the preceding direction. The flanged end portions of each pair of members 15, 16 and one end of a channel-shaped bumper cross-member 20 with outwardly turned flanges are now butt-welded to each of the channel shaped side members 10, the compensating movement is at right angles to both previous directions. Bending during forming of the frame is thus avoided and the setting up of strains thus eliminated.

[Class 97 (iii)] [Also in Group XL] In electric hygrometric apparatus in which variation, due to moisture deposit, of the resistance of a normally insulating path between two conductors is indicated, the indicating current alsc controls a heater so that increase of current evaporates the moisture and reduces the current whereby the apparatus is rapidly conditioned tc give a fresh indication. As described the hygroscopic element consisting of conductors 8, 10 is carried by a lamp 6 which also forms the heater, the indication being given by lamp 2 when a gas discharge tube 4 operates. The normal grid and anode A.C. potentials derived from transformer 3 are out of phase so that the tube is non-conducting, but when the hygroscopic element conducts, the grid of the tube becomes positive half cycles of anode potential so that the tube passes current, lights lamp 2 and heats lamp 6 to evaporate the moisture. Lamp 6 may be normally heated to some extent by the provision of resistance 11. The hygroscopic element may also be formed by winding on 3 wires and removing the central one to form the path which by using fine wire may be small enough to be bridged by moisture particles. The arrangement may be preferentially sensitive to moisture drops rather than dew.
