Title: Improvements in or relating to safety signalling on railways
IPC: B61L23/12
Filed: 1936-06-16
Abstract: 476,882. Railway signalling systems. PEARCE, C. R. June 16, 1936, No. 16704. [Class 105] The " train-on-line key of a block signalling instrument is locked in the operative position, after movement thereto, until an end-vehicle contact on the train closes a switch to energize a release magnet. The depressed " train-on-line " key 2 has its raised rear end, Fig. 2, held up by a lug 10 on a spring retracted armature 6, pivoted at 8. When the magnet 5 is energized the armature 6 moves to the dotted position and is held there by a pin 13 entering a notch 15 in a leaf spring 11. When the " train-on-line " key 2 now rises, after the signalman has moved the usual slide catch 3, Fig. 4, at the front of the instrument, the rear end descends on the leaf spring 11 to free the armature pin 13 from the notch 15 whereupon the armature moves to place the lug 10 in the ready position against the side face of the rear end of the key. The " lineclear " key 1 cannot be operated until the " train-on-line " key 2 has been released as a pivoted lever 17 otherwise holds up the key 1. Another arrangement consists in fixing on the sliding catch a stop block which abuts the side face of the depressed " train-on-line " key. Fig 5 shows an end-vehicle contact detachably clamped on the tie bar 26 of the axle-box guide and consisting of two arms 20 pivoted together at 21 and joined by a screw bolt 24 with an extension 22 acting as the contact; a roller may be fitted on the extension 22.

Title: Improvements in or relating to the manufacture of porous sintered metal elements
IPC: H01J9/04
Filed: 1953-06-23
Abstract: 726,032. Powder metallurgy. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 23, 1953 [June 26, 1952], No. 17362/53. Classes 83 (2) and 83 (4). A method of making a porous sintered refractory metal member, preferably for use in a dispenser type cathode comprises forming a body of refractory metal powder, sintering the body, mechanically shaping the body to the required shape, oxidizing the surface of the body to a depth at least equal to the layer of glaze formed thereon by the shaping operation, and heating the oxidized body in a reducing atmosphere at a temperature at which the oxides are reduced to metal and the refractory metal is recrystallized. A porous plug 4 for a dispenser type cathode 1 is formed by pressing a powder of tungsten, molybdenum, tantalum, titanium or hafnium into a bar at a pressure of about 2000 kg./sq. cm. and sintering at 2200‹ to 2400‹ C. The bar is then swaged to size and cut into a plurality of plugs. Due to the swaging and cutting, a metallic sheen or glaze is formed on the surface of the plug and this reduces the porosity. The surface is then oxidized by heating the plug in air or in an atmosphere containing a large proportion of oxygen at temperature of about 1000‹ C. for about one minute. The plugs are then heated in a hydrogen or hydrogen-nitrogen atmosphere at a temperature of about 1000‹ C. to reduce the oxides and this restores the porosity to its desired value. In the manufacture of a dispenser-type cathode, the plug 4 is welded to a cylindrical tube 2 of molybdenum. Specification 641,581, [Group XL (a)], is referred to.

Abstract: 979,062. Variable - speed friction gear. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 18, 1961 [May 18, 1960], No. 17606/60, Heading F2D. Variable-speed friction gearing of the toric disc and precessional roller type is provided with means for equalizing the load between the rollers. As shown diagrammatically in Fig. 1 each roller 22 is rotatably mounted in a carrier 21 universally jointed at 18 to a cranked rocker 4 which is pivoted at 1 on a fixed reaction plate (not shown) and the free end of which engages a recess 10 in a common control member 13 which is rotatable to tilt all the carriers equally but which floats radially and is shifted radially by an overloaded roller to move this roller to a lower ratio position and the other rollers to higher ratio positions. The free ends 24 of the roller carriers 21 ride in sockets 25 anchored to the reaction plate. In a modification the ends 24 of the roller carriers are carried by rockers engaging a second radially floating control member which is used during reverse rotation of the transmission, the control member 13 being free from rotational restraint during reverse rotation. The precession of the rollers may be terminated by a screwing action, the universal joint 18 being formed by a ball disposed in a socket provided in the rocker and the roller carrier having a screw connection with the ball, alternatively the axis about which the roller carrier pivots may be at an angle to the plane of the torus centre circle. In the embodiment of Fig. 6 a roller carrier 440 has a screw connection with a pin 443 pivoted to a rocker 446 which has a ball-ended arm 450 engaging a notch 451 in a common radially floating non-rotatable member 452 which equalizes the load between the rollers. Tilting of the carriers 440 to vary the ratio is effected by angular adjustment of a common control ring 455 having notches 454 engaged by semi-circular webs 453 formed on the carriers. The invention may also be applied to a transmission of the type having two sets of rollers co-operating with two driving discs and a central driven disc having a toroidal track on each side. U.S.A.

Abstract: 744,978. Batteries. MINISTER OF NATIONAL DEFENCE OF H.M. CANADIAN GOVERNMENT. July 11, 1952 [July 11, 1951], No. 17627/52. Class 53. A primary cell comprises an anode of a metal high in the electro-chemical series, a starting cathode of a metal low in the electro-chemical series spaced from but close to at least part of the anode, and an electrolyte comprising a soluble salt of a metal low in the electrochemical series, the electrolyte being such that, when the external circuit is closed, a layer of the electrolyte metal and an intervening insulating layer of products of corrosion of the anode metal are electrolytically deposited over the surface of the anode, the layer of electrolyte metal, as it grows, coming into contact with the starting cathode. Referring to Fig. 1, the starting cathode 10 may be in the form of a thin metal foil backed on to the anode 11 of an adjacent cell, or it may be backed on to the anode by electroplating or a similar process. The anode 11 may be formed with a series of pins 12 defining between them spaces for the electrolyte. The anode is preferably of magnesium, the cathode of copper or silver, and the electrolyte a soluble copper or silver salt in dilute acid or in sea water, for example copper sulphate in dilute sulphuric acid. The battery shown comprises three cells arranged in a hard rubber casing 16. When a load is connected between anode and cathode, copper is deposited on the anode, and after a time corrosion products on the anode provide almost molecular separation between the anode and the deposited copper which forms a secondary cathode linked with the starting cathode. Currents of 100 amps. through an external resistance of 0.01 ohms may then be obtained. To decrease the time lag before maximum current is produced, the anode may be pre-treated in an electrolyte bath, for example of dilute acid or sea water, so as to pre-form the layer of corrosion product. In a modification, Fig. 3 (not shown), the electrodes are spaced from the container to provide more room for electrolyte. Fig. 2 shows a further modification in which the starting cathode 25 is positioned between the pins 29 of the anode. The electrolyte may be circulated through the cell from a vented reservoir 31 by a pump 33.
