Abstract: 1287922 Lift control systems WESTING- HOUSE ELECTRIC CORP 24 Nov 1969 [17 Dec 1968 (2)] 20974/72 Divided out of 1287921 Heading B8L The description is identical to that of the Parent Specification but the claims relate to the simulation of an alternative vehicle distribution pattern and the re-allocation of calls to vehicles according to the new pattern if this would improve the service. Specifically, if a call exists for travel in one direction which cannot be allocated in the normal way then the leading car travelling in the opposite direction is assumed to be free (i.e., this is "simulated"). Provided this does not result in a new unanswerable demand being set up this assumption is acted upon, the car thus made "free" being stopped (with doors closed) and the unanswered call allocated to it. Its original calls are then taken over by the next car travelling in said opposite direction. The car is simulated as "free" by blanking calls ahead of it.

Title: Device for recording the displacements in longitude and in latitude of ships and airships
Filed: 1934-07-19
Abstract: 423,227. Course-recording apparatus. REYMOND, H. C., 10, Rue St. Augustin, Paris. July 19, 1934, No. 21187. Convention date, Aug. 5, 1933. [Class 97 (ii)) [See also Group XXXV] A voltage or current proportionate to the speed of a ship or aircraft is generated and automatically divided by means under compass control into two parts which are proportional to the sine and cosine of the course and actuate volt- or ampere-hourmeters, graduated to indicate the displacements of the ship in longitude and latitude. When a source of continuous current 1 supplying a voltage proportional to the speed is used, two potentiometers 2, 3 with sliding contacts 4, 5 may be connected in parallel to the source. The sliders 4, 5 are actuated through rods 6, 7 by a pin 10 on a disc 11 orientated by a gyro compass repeater 12 and engaging slots 8, 9 mounted at right angles on the rods 6, 7, respectively. The sliders move so that their distances 04, 0<1>5, from the centres of the potentiometers are proportional respectively to the sine and cosine of the course. A volthourmeter 15 connected between the slider 5 and the middle point 16 of a resistance 17 in parallel with resistances 2, 3, may be graduated to indicate the N-5 displacement as a distance or in degrees of latitude. A volthourmeter connected between the slider 4 and the point 16 may be graduated to show the E-W displacement as a distance. An arrangement whereby the E-W displacement may be indicated in degrees of longitude is shown in Fig. 3. The slider 4 is connected through a potentiometer 22 to the point 0 and a slider 23 moved by the latitude meter 15 is connected through a volthourmeter 14 graduated in degrees of longitude to the point 16. When an alternating current generator 18 supplying a singlephase voltage proportional to the speed is used, the generator feeds a fixed frame 19, Fig. 4. Two frames 20, 21 at right angles are rotated together about a diameter of the frame 19 by a compass repeater 12. The frame 21 may be connected to a volthourmeter 15 graduated to indicate N-S displacement as a distance or in degrees of latitude. The frame 20 may be connected to a volthourmeter graduated to indicate E-W displacement as a distance or as shown to a fixed frame 19<1>. In the latter case a frame 20<1> rotated about a diameter of the frame 19<1> by the latitude meter 15 is connected to a volthourmeter 14 graduated in degrees of longitude. The effect of drift or currents may be accounted for by providing the meters 14, 15 with a second winding fed by a device similar to those described but adjusted by hand in accordance with the speed and direction of the drift and currents.

Title: Superconducting magnets
IPC: H01F6/06
Filed: 1966-05-13
Abstract: 1,140,696. Superconductors; electromagnets. UNION CARBIDE CORP. 13 May, 1966 [14 May, 1965], No. 21272/66. Headings H1K and H1P. A superconducting magnet comprises superconducting layers alternating with layers of non-superconducting material. The superconducting layers, which are each constituted of particles bonded together at their interfaces and preferably form a helix, are mutually isolated except at their ends, through which they are interconnected. The superconducting layers are preferably deposited over a cylindrical substrate and then machined to helical form. The material of the layers or if it is a compound or alloy, its components, may be introduced in powdered form into a plasma jet produced by passing a gas stream through an electric arc. Layers of niobium-zirconium alloy, vanadium silicide, niobium aluminide, niobium stannide and niobium-tin-zirconium alloy may be formed by directing such a jet on a brass or aluminium substrate which may be cooled during the process. The plasma may in this case consist of argon or helium. On the other hand niobium oxynitride compounds may be deposited by detonating a fuel charge in a confined chamber and introducing niobium powder into the resulting plasma. In all cases the surfaces of the particles become molten so that they adhere when deposited. The superconducting properties are improved by subsequent heat treatment. In the preferred method the first superconductor layer is deposited on a cooled copper mandrel and layers of alumina and copper deposited over this after it has been machined to helical form. The process is then repeated to give the requisite number of layers. The resulting assembly, in which the superconducting helices may be connected in any series, parallel or series-parallel arrangement is shrink fitted into a cylindrical titanium or stainless steel casing.
