Title: Improvements in locking mechanism more particularly for railway wagon and other doors, but also applicable to other articles
IPC: E05B65/14
Filed: 1922-03-29
Abstract: 199,175. Westcott, A. C. S., and Warner, D. March 29, 1922. Locks, preventing operation of; locks, squarekey; lock mechanism, slider type.-A wagon door lock in which a square key operates a pinion to actuate a racked balt, has a steel plate normally obstructing the square hole in the pinion, and moved aside by use. of a key of correct construction. The key comprises a central spindle a, the end of which is squared to engage a square hole t in the pinion b, and a sloove e freely rotatablo upon the spindle a. The end h of the sleeve e is cone-shaped, and has an interior screwthread corresponding to that on the part i of a bush having an enlarged part with circular recesses p engaging the teeth of a spring-controlled pinion q which also engages the rack r on the steel obstructing plate s. The spring q<1> normally holds the bush i and the plate s in the position shown in Fig. 2, so that the hole w in the plate is not aligned with the hole t in the pinion b, preventing insertion of the key shank a to operate the bolt. On insertion of the key the end h of the sleeve e comes into contact with the screw-threaded part i of the bush. The sleeve is then turned either by means of the shaft a and clutch formed by the projection f on the collar g, or by independent means, causing the part i to enter the sleeve and until the sleeve end is in contact with the collar o of the casing n in which the bush slides guided by the pin l and slot l<1> By this time, the conical end h of the sleeve has pushed aside the radially arranged members j, pressed inwards by the circular spring u, by engagement with their arms k, removing their bevelled arms v from the circular depressions p of the lower part of the bush as shown in Fig. 3. Further rotation of the sleeve then causes the lifting of the bush until the enlarged part is in contact with the lower surface of the collar o, as shown in Fig. 3. The upward travel of the bush 'causes the recesses p to rotate the pinion q against its spring q<1>, so moving the racked plate s to bring the hole w therein opposite the hole t, when the shank a can be thrust into engagement with the pinion b. Turning the pinion b by means of the kev shank a turns a wheel 2 rigid with a spindle 3 on which is fixed a wheel 4 meshing with the rack d on the bolt c, which is thereby moved into or out of its socket 11. In order to avoid accidental displacement of the parts by the jolting of the wagon, a catch 5 fixed to the plate is held by the spring q<1> of the pinion q in engagement with the pinion 5. until the plate s is moved by the key. Geared toothed wheels may be added so that vertical and horizontal bolts may be operated simultaneously.

Title: Improvements in or relating to supply systems for arc welding
IPC: B23K9/10
Filed: 1962-03-09
Abstract: 948,220. Welding by fusion. UNION CARBIDE CORPORATION. March 9, 1962 [March 13, 1961], No. 9181/62. Heading B3R. [Also in Division H2] A supply system for arc-welding apparatus using a gas-shielded consumable electrode subjected to shortcircuitng type metal transfer comprises a variable voltage transformer 12, a full-wave rectifier 13 and an adjustable filter choke 16, the circular wire electrode 17 being fed by a motor 18 through a torch T supplied with shielding gas. The volt/ampere output characteristic is determined for the minimum open-circuit voltage of the transformer 12 by the minimum short-circuit current required to produce effective melting and squeezing off of the molten droplets from the electrode. This minimum short-circuit current I M  is defined by: I M  = (400# r S)¢ where r = radius of the electrode 17 (cms.) S = surface tension of the molten electrode (dynes/cm.) at the temperature at which metal leaves the electrode. This current represents the minimum necessary for consistent welds with an electrode of given material and size, and for a given radius the minimum current required from the power supply is determined by the maximum value of the short-circuit currents for the materials to be welded. The volt/ampere characteristics of the system for fixed or variable regulation are discussed, Fig. 4 (not shown), and suitable values are given for the inductance of choke 16 and the output voltage of the transformer 12.

Title: Improvements in and relating to hydraulic pumps
IPC: F04B49/12
Filed: 1948-04-02
Abstract: 648,716. Reciprocating pumps. CROUCHER, A. H. April 2, 1948, No. 9363. [Class 102(i)] [Also in Group XXVI] In a reciprocating pump, a driving shaft 1 has an eccentric portion 7 on which is mounted two eccentric annular hubs 9, 10 secured together and mounted on bearings 13 and 8. A sun wheel 19 is driven by the shaft 1 and a second sun wheel 21 is mounted on the sleeve 22. Planet Wheels 26 engage the sun wheels and annuli 32, 33 and the drive from the sleeve 22 is transmitted through a Hcokes joint 24, 18 to the annular hub 9, 10 so that the hub gyrates. The eccentricity may be adjusted by rotating the annulus 33 through the pinion 38 and rack 36. The hub has a series of spherical sockets 64 and stationary members 4, 5 have spherical sockets 65 and between each pair of sockets a piston 60 and cylinder 61 are arranged. Each pair of pistons and cylinders are pressed apart by a spring 74 to engage the sockets; the spherical end of each piston has a flat to permit liquid pressure to act upon it and relieve the pressure on the socket. A central flange 39 on the hub operates within a stationary ring 46 to form a boost pump (see Group XXVI).

Title: Improvements in or relating to electrical signal-translating devices and methods of manufacturing such devices
IPC: C03B18/04
Filed: 1962-03-12
Abstract: 990,037. Semi-conductor devices. PHILCO CORPORATION. March 12, 1962 [March 10, 1961], No. 9387/62. Heading H1K. A signal translating device comprises a layer of conductive material in rectifying contact with a surface of a semi-conductor body and a conductive contact separated from the conductive layer by an insulating film which is sufficiently thin to allow tunnelling. In Fig. 1, a body 10 of single crystal N-type germanium has a layer 14 200  thick of aluminium evaporated upon one surface so as to provide a surface barrier or rectifying contact. A gold film 16, 200  thick, provides ohmic contact to the aluminium layer 14 and is also in rectifying contact with body 10. Layer 14 is exposed to air to form an aluminium oxide film 20 which is about 20  thick. A gold surfaced electrode 24 contacts the aluminium oxide layer. The device in operation resembles a transistor, electrodes 12, 16 and 24 corresponding to collector, base and emitter respectively. If emitter electrode 24 is biased negatively (about 3 volts) with respect to base layer 14, carriers tunnel through the aluminium oxide layer 20 with sufficient energy to surmount the potential barrier between base layer 14 and semi-conductor body 10 and thus reach the collector electrode 12 which is positively biased to reverse bias the potential barrier. Since the impedance of the collector circuit greatly exceeds that of the emitter circuit, power gain may be provided in the load 32. The thin gold layer may be produced by evaporating for 1/ 5  second by means of a shutter control. Gallium, nickel, indium, caesium, lithium or aluminium may also be used for the emitter and the oxide film may be produced by anodic oxidation. Nitride films may be used instead of oxides or the insulating film may be a film of organic material. The base layer 14 may alternatively be of silver, copper, titanium or tantalum, and silicon may be used in place of germanium. The potential barrier between the base and collector regions may be provided by means of a P-layer produced by diffusion, micro-alloying or epitaxial growth; a weak N-type layer may be used instead of a P-type layer to form the barrier with the N-type body. The base layer may be annular in form or may consist of small active areas.
