Title: Improvements in Train Stop and Speed Control Systems for Railways.
Inventor: STARIE BERNARD
IPC: B61L3/22
Filed: 1917-02-07
Abstract: 112,005. Starie, B. Dec. 14, 1916, [Convention date]. Track apparatus actuating signals on trains for stopping trains.- Signalling and train-stopping apparatus on a train is controlled by the changes in magnitude of alternating current in a main circuit and two branch circuits on the train, one of which includes the frame of the vehicle, owing to the action of other branch circuits on the track which include insulated joints, inductances or condensers inserted or cut out by the movements of the visual signals on the track. Fig. 6 shows diagrammatically three signals or relays 8, 9, 10 supplied from an alternating-current generator. The relay 10 is in the main circuit; the relay 8 in a, branch circuit including a condenser 15; the relay 9 in a branch circuit including the axles 17, 18 and the vehicle frame 13 which has a considerable impedance. The rails between the axles 17, 18 also have a considerable importance. The apparatus is adjusted. so that normally, the relay 8 receives a large leading current, the relays 9 and 10 a smaller lagging current. At signalling points, the impedance of the track rails is increased either by a rail of greater cross-section or by a heavy copper conductor bonded to the rail and condensers are arranged in branch circuits closed by switches on the signals. At a danger signal, the additional impedance in the branch circuit due to the rails causes the lagging current in the relay 9 to equal the leading current in the relay 8, and the relay 10 receives practically no current. At a caution signal, a capacity 56 is included in parallel to the track rail and causes the current in the relay 9 to become zero, and the relay 10 receives full current. At a clear signal, the additional impedance of the track rails is balanced by a capacity 63 in parallel with the rail circuits. Fig. 6 shows a high-frequency generator and thermo-junction relays 8, 9, 10, controlling relays 31, 32, 33, which are normally energized but are momentarily deenergized by reduction of current through the relays 8, 9, 10. Relays 32, 33 control self-holding relays 36, 44 which in turn and in conjunction with the speed indicator 39 control the signals 43, 49 and brake valves 42, 48, in such a way that the brake valves can only be re-set after reduction of speed. Relay 31 controls the brake magnet 42 and a signal 52 which indicates that the apparatus is in working order. Since any defective circuit de-energizes the relay 8, this trouble is indicated by the signal 52 and stoppage of the train.

Title: Improvements relating to coke ovens and the like
IPC: C10B5/00
Filed: 1920-01-24
Abstract: 150,983. American Coke & Chemical Co., (Assignees of Roberts, A.). Sept. 8, 1919, [Convention date]. Coke ovens.-In an oven in which a network of interconnected passages is formed in the heating-walls, and in which the flow of heating-gases is reversed at intervals, the combustion is reinforced during the gas travel in either direction. The heating-walls are built up of notched blocks, and each wall is divided by partitions 41, 42, 43 into sections 37, 38 connected in pairs by horizontal passages 45. At the lower end of each section are series of gas and air ports 50, 51 respectively, and the supply connexions are so made that when gas and air are being delivered at the base of one section of a pair, the supplies to the other are cut off, the air ports of this section acting as waste-gas outlets. Gas ports 52 are also provided at the upper ends of the sections, and the heating is equalized by supplying the full quantity of air, and a proportion only, say half of the gas, through the ports 51, 50 respectively, the remainder of the gas being delivered through the ports 52 at the top of the adjacent connected section. In the oven construction shown, each wall between adjacent ovens comprises two heating-walls 26, 27 with a blank or partition wall 28 between. Beneath the ovens are regenerators 67 arranged in sets running parallel to the length of the ovens, each set comprising as many compartments as there are sections in the heating-wall, and beneath each set are two flues 68, 69 tapering in opposite directions and connected on the one hand to alternate compartments, and on the other through a reversing-device with a chimney flue or the atmosphere. At their upper ends the compartments open into a pair of longitudinal flues 78, 79 from which lead the ports 51 at the base of the heating-wall sections 37, 38. Gas is supplied from the top of the oven to the burner ports 50 through vertical conduits on the partition wall 28, the connexion between the conduits and ports being made through semi-circular passages in blocks, which extend from the heating-wall into the partition wall. Similarly at the upper end of the wall the gas passages 52 are formed in blocks extending from the partition wall into the heating-wall, so that the gas connexions will not be disturbed owing to expansion and contraction of the brickwork. Inspection openings 63 leading to the cross connecting-flues 45 are provided to facilitate adjustment of damper blocks 65. The Specification as open to inspection under Sect. 91 (3) (a) comprises also arrangements for clearing out carbon deposits from the gas passages by admitting air, and for preventing excessive expansion by the provision of distributed joints in the structure. This subject-matter does not appear in the Specification as accepted, but forms the subject-matter of Specifications 165,738 and 165,740.

Abstract: 1,255,133. Polarized electromagnetic relays. MATSUSHITA ELECTRIC WORKS Ltd., and H. SAYER. 19 Jan., 1970 [20 Jan., 1969], No. 2446770. Heading H1N. A polarized relay which may be one side stable, bi-stable, centre-stable or three position stable has a permanent magnet which provides a magnetic flux that falls with rising temperature, an armature which is displaced by the permanent magnet flux on energization of a coil and forces are transmitted to a contact via spring means which are stressed after the contacts have engaged. As shown, two permanent magnets 5, 5<SP>1</SP> are mounted between pole members 4, 4<SP>1</SP> and may have different temperature characteristics. Contact actuating arms 14 are attached to the ends of the centrally pivoted armature 1 which is surrounded by the coil 7 on a former 6. The insulated ends 15 of the arms 14 each extend between the blades 23, 23<SP>1</SP> of a respective bifurcated contact spring 22 which is mounted on a terminal pin in the base 19 and carries two movable contact members 24, 24<SP>1</SP> which co-operate with fixed contacts 21, 21, on terminals 20, 20<SP>1</SP>. The blades 23, 23<SP>1</SP> are bent to a considerable extent after contact engagement to provide a restoring force which permits reverse operation of the relay at smaller power than would otherwise be required. The contact force can be varied by adjustment in direction V of the end 15 of the arm 14. A lug 81 or 811 on the member 4 or 4<SP>1</SP> can be bent to influence the end of a respective bent spring 11 attached to the armature 1 and forming a non-remanent spacer between the armature and pole member. Without the influence of a spring 11 the relay is bi-stable (Fig. 7, not shown) and is one side stable with a spring 11 effective (Fig. 8, not shown). Fig. 11 shows an alternative armature biasing arrangement with a projection 17 on the armature 1 engaged between blade springs 12, 12<SP>1</SP> which can be adjusted by bending mountings 1 and by bending a stop 16. With strong springs 12, 12<SP>1</SP> the relay is centre-stable (Fig. 9, not shown), but with weaker springs the relay can be three position stable (Fig. 10, not shown).
