Title: Apparatus for laterally aligning railroad tracks
IPC: E01B33/08
Filed: 1968-11-11
Abstract: 1,248,076. Electric correspondence control systems. F. PLASSER. Nov. 11, 1968 [Nov. 14, 1967], No. 53237/68. Heading G1N. Apparatus for laterally aligning a railway track comprises potentiometric means for measuring the curvature to produce an error signal which is fed to hydraulic rams controlling the aligning tools, the applied force being proportional to the error signal. The track curvature is represented by the angle between a long taut wire 6 Fig.3 extending between a front truck 8 and rear truck 10 mounted on a bogie frame and two short wires 7, 7' extending between a central tool truck 4<1> and each of the trucks 8, 10, only the rear short wire, e. g. 7, being used for a given direction of travel, its displacement from parallelolism with wire 6 being measured by a rotary potentiometer 19 Fig. 4 on a truck 9 intermediate between trucks 4<1>, 10. The potentiometer slider is positioned by a motor 21 associated with a follow-up switch 20 straddling wire 6. When the bogie is located on a curved portion of the track the follow-up switch 20 energizes motor 21 to rotate a spindle 18 carrying the switch 20 and potentiometer 19. The consequent displacement of the potentiometer slider feeds a measuring signal to a meter 31 in opposition to a reference signal from pre-set potentiometer 33, the difference being fed via amplifier 34 to hydraulic servo-valve 17 controlling the pressure developed by rams 11 of track aligning tools 4. The rams may be used independently of the measuring system by operating switch 38. In an alternative arrangement Fig. 6, a single taut wire 44 is attached at its centre to the tool truck 4' and the wire ends are slidable laterally on the front and rear trucks 8, 10. Rotary potentiometers 47, 48 mounted on the tool truck 4<1> and on the intermediate truck 9 are attached to the wire 44 to measure the curvature of the bogie and the potentiometer slider signals are combined in a desired ratio to energize the rams of the track aligning tools.

Title: Superconductive circuits
IPC: H03K3/38
Filed: 1974-12-10
Abstract: 1483110 Superconductive circuits INTERNATIONAL BUSINESS MACHINES CORP 10 Dec 1974 [13 Dec 1973] 53270/74 Heading H3X A monostable or bi-stable trigger circuit is formed by two controlled Josephson junctions J1, J2, Fig. 1, connected in series to a constant voltage source, each junction being shunted by a respective load RL1, RL2. Each junction may be switched from the superconducting to the normal state by a respective control current IC1, IC2, the normal conducting state of a junction producing a voltage drop such that the other junction operates in the superconducting state. A symmetrical bi-stable circuit is shown in Fig. 4 in which junctions J1, J2 of like properties are used. A further Josephson junction J3 in the normal conducting state regulates the supply voltage source by providing a constant voltage drop Vg. This circuit may be formed as an integrated assembly as shown in Fig. 5, using a niobium superconducting base (not shown) covered with a niobium oxide insulating layer. Superconductive lines such as 7 8 and the lower electrodes of the Josephson junctions J1, J2, J3 are formed on this layer, followed in turn by the deposition of lead oxide or indium oxide to form the junction layers, and the completion of the remaining superconductive electrodes and connecting lines. Line necks such as L are provided where the circuit inductances must be increased. Resistors 3, 4, 5, 6 and Rs are then vapour deposited, and the assembly is completed by forming control lines 1, 2 over a silicon oxide insulating layer. A similar constructional method is used to form an integrated assembly, Figs. 6 and 7, in which the Josephson junction J1 has a smaller area than junction J2 (represented by a smaller X in Fig. 7 and subsequently), and plural series control lines 9, 10 effective in opposite respects on the two junctions are provided. Such an arrangement provides monostable operation for output current in load RL2 and may provide the logical operations OR or AND by the choice of appropriate control current thresholds. By reversing the relative areas of J1 and J2, Fig. 10, an inverter suitable for performing the logical functions NOR or NAND is provided. By using a bias current Ib the operating parameter tolerances of the circuit may be improved. Monostable operation is also obtainable with equal area Josephson junctions by the use of differently dimensioned loads. A bias of one junction only or differential bias on both junctions are alternatives. The Specification also discusses regulation of the bias current Ibc by the use of a parallel combination of a resistor GO and a Josephson junction GNN, Fig. 12. A combination of Josephson junction circuits 11 with source voltage and bias current stabilization by additional Josephson junctions is shown in Fig. 15. Other stabilizing circuits are described, Figs. 14 and 16 (not shown).

Abstract: 1,211,101. Recovering solvent vapours by adsorption. AMEG HANDELS-G.m.b.H. & CO. K.G. 24 Nov., 1967 [26 Nov., 1966], No: 53572/67. Heading B1L. Air laden with tri- or per-chlorethylene is passed by fan 3 to and through charcoal bed 1a, the purified air leaving through opening 5. Simultaneously, steam produced in integral steam generator 6 is passed up through superheater 31 and then through solvent-laden bed 2a, desorbing the solvent which passes with the steam out through pipes 86 and 10 to counter-current condenser 11 before passing by line 12 to separator 12 where it is recovered; water heated in condenser 11 passes by line 23 to steam generator 6. When the beds la, 2a are respectively laden and regenerated, flaps 18, 19 are switched through 90‹, thereby also switching the functions of the 'beds. This switching is performed automatically by means of differential pressure valve 9. The particular construction of the adsorber is such that vapour-laden charcoal particles falling from beds la, 2a do not come into direct contact with heater surfaces, thereby minimizing the risk of phosgene formation. In other embodiments, vapour is passed upward and steam downward through the beds (see Fig. 3, not shown), and particles from a bed positioned directly above the steam generator and superheater are prevented from contact therewith by means of domed surfaces which cover the heaters (see Fig. 2, not shown).
