Title: An electrical installation for the operation of a movable body from a distance
IPC: G08C19/38
Filed: 1923-07-04
Abstract: 221,041. Japolsky, N., Kostenko, M., Woronoff, B., and Sabaneew, C. July 4, 1923. Distant control systems and apparatus.-The movement of one body controls that of another at a distance through the agency of a constantspeed alternating-current commutator-generator, the movement of the controlling body serving to supply to the generator an excitation-field of which the direction of rotation and the current frequency depend on the direction and speed of movement of the controlling body and the tension and frequency of this excitation current determine the tension and frequency of the current supplied by the generator to the stator of a synchronous motor of which the rotor moves the controlled body. The commutator-generator is preferably of the type described in Specification 210,482. In the arrangement shown in Fig. 1, the control is effected from a crank f by which a closed coil c, slip rings a, b, and the sections d of a commutator are rotated in relation to fixed brushes A, B, C. Direct current is supplied through brushes e to the rings a, b, and each of the brushes A, B, and C is connected to one of the three excitation coils W<1> on the stator of the commutator-generator M<2>. Three other stator windings Ws are connected to the rotor winding W<r> through the commutator and brushes and to the terminals of the generator which are connected to the stator winding of a three-phase synchronous motor M<1> provided with a rotating field supplied with direct current. The rotor of this motor actuates the controlled body. In a modification the excitation coils W<1> are supplied from three brushes bearing on the sections of a dynamo commutator driven from the crank f provided with a fixed field supplied with direct current. The apparatus is applicable for effecting from a distance the simultaneous angular movement of a number of gun turrets. Each turret is provided with a worm wheel for actuation by a worm on the rotor shaft of a corresponding motor M<1>, and the stator windings of these motors are connected in parallel to the output circuit of the commutator generator. An equal angular movement is thus imparted to .each turret. To impart to each turret in addition a predetermined supplementary angular movement depending upon the location of the gun, the stator of each motor is rotatable from the rotor shaft of an auxiliary synchronous motor controlled through an auxiliary commutatorgenerator from the crank-shaft of an auxiliary controlling device. In a modification, Fig. 4, of this arrangement, a single motor M is used in place of the motor M<1> and its associated auxiliary motor and its rotor is provided with three windings connected through rings a, b, c to the brushes of the auxiliary control device m<3>.

Abstract: 495,104. Making radiators. BREVETS AERO-MECANIQUES SOC. ANON. Feb. 1, 1937, No. 18372. Void. Convention date, Nov. 12, 1936. Divided out of 495,096, [Group XIII]. [Classes 83 (ii) and 83 (iv)] Welding ; corrugating.-In making heat interchangers, such as radiators for aircraft engines, particularly such as are described in Specification 495,096, and consisting of elements each comprising two superposed metal sheets welded together continuously along certain lines, the sheets are first passed through the electrode wheels of a welding machine in order to corrugate the sheet and are then again passed through the wheels with the current on in order to effect the weld. The sheets 6 are clamped by bolts 29 passing through the stamped headers 4 to patterns 26 of sectional iron which are carried by a frame oscillatable about a pivot 30 so as to traverse the sheets between the electrode wheels 24 of a welding machine'. The two sheets are placed on opposite sides of a series of rods 7 secured by springs or bolts to the frame and serving to support the sheets between lines l of the welds. After the first weld is effected the frame is moved on its axis which is provided with a series of parallel holes 32 to which the frame is secured by a pin 31. The lines of welds are thus effected in succession. The end of each seam may be spot-welded on account of the proximity of the wheel electrodes with the headers. The edges of the sheets are subsequently welded together by two overlapping line welds. The sliding and rotational movement of the frame may be effected simultaneously so as to give helical welding lines. Corrugating wheels may be mounted coaxially with the welding wheels so that one line is corrugated while the previous line is welded. In a modification corrugating and welding may be effected simultaneously. The pattern may be curved, as shown, to form curved elements or may be replaced by other shapes, e.g. conical. In the latter case the bearings of the axis may be adjusted by screws to bring the lines successively between the electrode wheels.

Title: Method of forming a superconductive metallic film
Inventor: GEBAUER CONSTANTINE ALOIS NEU
IPC: H01L39/00
Filed: 1965-04-30
Abstract: A superconductive metal alloy film (e.g. of niobium-tin alloy) is formed on a substrate (e.g. of W, stainless steel, quartz, mica, MgO or soda-lime glass) by disposing the substrate, a first superconductive metal having a melting point above 1500 DEG K and a vapour pressure of at least 10-4 mms Hg at its melting point, and a second superconductive metal having a melting point lower than that of the first superconductive metal, within an evacuable chamber, evacuating the chamber to a pressure of from 1 x 10-9 to 5 x 10-5 mms Hg, evaporating sufficient of the first superconductive metal to getter oxygen and oxygen-containing compounds within the chamber, and thereafter co-evaporating the first and second superconductive metals and simultaneously co-condensing the evaporated metals on the substrate. The first superconductive metal may be heated by electron bombardment or by induction heating. A shield may be maintained between the first superconductive metal and the substrate during the gettering.  The substrate may be maintained at a temperature above or below 900 DEG C. during the deposition.  By controlling the evaporation temperatures of Nb and Sn, the atomic ratio of the Nb to Sn deposited on the substrate can be arranged to be greater than, equal to or less than 3 to 1.  The metal deposited on the substrate may, as a further step, be annealed at above 900 DEG C. The apparatus used is the same as that described in the parent Specification 1,057,048.

In the fully mechanised driving of tunnels, that zone at the head of the tunnel in which suspended dust is mainly produced is separated from that zone in which heat is mainly produced, i.e. by the driving machinery and the dust-laden and heated air is drawn off from the zones and replaced by fresh air, a smaller quantity of fresh air being supplied for flushing the dust-laden zone than is supplied for flushing the heated zone. A partition 2a is provided directly behind a rotating tool carrier 1 and the partition includes suction nozzles 3 through which dust laden air is carried by a collecting pipe 5 to a dust separator 7 on the outlet side of which there is a suction fan 8. Dust free air is delivered to the gallery behind the working positions by the duct 9, whilst dust is collected in a sack filling device 12. A further partition 2b, which may be transparent, may be provided behind the driving motors and gearing 18, 19 and fresh air is delivered to this compartment via the casing of a debris conveyer 16 feeding an endless conveyer 17. Air is also supplied to both compartments by passing around the edges of the partitions which do not fit tightly against the wall of the tunnel. The fresh air supply for the tunnel may pass through cooling apparatus 14, 15 and then be divided into two paths along the inside and outside of tube 13. The tube 13 projects so that the cooler air passing through it is directed to the working positions whilst the warmer air passing through the casing of the tube mixes with the air issuing from the working positions to cool it. In a modification two coolers may be used, one for each air stream. In a further modification the second partition 2b may be dispensed with, the machinery then being encased and supplied with fresh air.
