Patent GB-764763-A (GB)
Title: Exothermic alloy addition agent
IPC: C21C7/06
Filed: 1955-03-28
Abstract: An addition agent for incorporating ferro-alloys in a ferrous melt comprises 2-8 per cent aluminium, 5-15 per cent sodium nitrate or 5-20 per cent sodium bichromate or chromate, the remainder being a ferro-alloy with or without an accelerator compound of an alkali or alkaline earth metal, e.g. lime, calcium fluoride, cryolite, calcium aluminate, sodium carbonate or sodium silicate, up to 10 per cent. The ferro-alloy contains a metal which is to be added to the ferrous melt, e.g. chromium, nickel, cobalt, copper, tungsten, vanadium, titanium, molybdenum, manganese or niobium, and may also contain the aluminium required as reducing agent.  Thus it may be ferro-chrome-aluminium alloy containing up to 50 per cent of aluminium, a ferro-chrome-silicon alloy or a ferro-chrome-silicon aluminium alloy.  The mixture is preferably briquetted, e.g. with a binder such as sodium silicate or an organic binder such as wood rosin or resin or sugar products or by recrystallizing the oxidizing agent constituent by melting, or from solution by addition of a small amount of water to the mixture followed by evaporation.

Title: Improvements in aerial arrays particularly for short-wave communication
IPC: H01Q21/26
Filed: 1940-05-20
Abstract: 539,602. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 20, 1940, No. 8971. Convention date, May 20, 1939. [Class 40 (v)] An aerial array for radiating a rotating field in a vertical direction comprises two or more sets of aerials in parallel planes which are located a quarter of a wave-length, or an odd number of quarterwave-lengths, (2n+1) #/4, apart in order to prevent reflection from the aerials into the feeder. The aerials may be constructed as described, for instance, in Specification 528,817. Fig. 3 shows two arrays, 5, 6, 7 and 51, 61, 71 of three-phase aerials each radiating a rotating field. Thus the horizontal aerials 5, 6, 7 are connected to the feeder 10 by paths 25, 26, 27 which differ from one another by one third of a wave-length, so that a rotating field is radiated vertically. A similar set of aerials 5<SP>1</SP>, 61, 7<SP>1</SP> are fed through extensions 35, 36, 37 of the same paths, these extensions being (2n+1) #/4 long ; and the aerials 5<SP>1</SP>, 61, 71 are oriented 90‹ forward with respect to the aerials 5, 6, 7, in order that the fields radiated vertically from the two sets may be in phase with one another. Reflection from the aerials back into the feeder is prevented by the two sets being separated by a length of (2n+1) #/4 of conductor. A similar arrangement employing two sets of four aerials, or turnstiles, fed in quadrature is described with reference to Fig. 4 (not shown). Further pairs of sets of aerials, similarly spaced, may be stacked vertically above the first pair.

Title: Improvements in transmission systems
IPC: H04B3/40
Filed: 1924-04-09
Abstract: 214,249. Western Electric Co., Ltd., (Assignees of Hoyt, R. S.). April 9, 1923, [Convention date]. Artificial lines and balancing networks.-Relates to the construction of a network to simulate the impedance of a transmission line over a wide range of frequencies, for balancing purposes in telephonic repeaters or for properly terminating a telephone line. The general equation for the impedance K of a line in terms of the resistance R, inductance L, capacity C and leakance G is the leakance being comparatively unimportant except at low frequencies. Expressions for the resistance and reactance components M, N of the impedance K are obtained to various degrees of approximation. In the case of open-wire lines, R is of secondary importance, and a rough value for K is k=(L/C)<¢>, which is termed the " normal impedance." The quantities (K-k) and E/k are termed the " excess impedance " and " relative impedance." The simplest network according to the invention is a mere resistance R, equal to the nominal impedance k, but over the voice frequency range this must be supplemented by an " excess-simulator " whose impedance J is approximately equal to the excess impedance (K-k). For large gauge open-wire lines, the excesssimulator may be a capacity C, equal to 2(LC)<¢>/R, but even then is inadequate at low frequencies. More accurate values for R<1>, C<1> are obtained by multiplying by x, the real part of the relative impedance K/k, which, if leakance can be neglected, is approximately independent of the frequency and is slightly greater than unity. Figs. 11<a> and 11<b> show in series with the resistance R equivalent excess-simulators which may be proportioned to give fairly precise results over a given frequency range by tentative design, which may be considerably reduced by a semigraphical method. If J=P+iQ, this consists in plotting curves between P, (M-k) and the frequency and between Q, N and the frequency, using as parameters arbitrary functions of the elements of the excess-simulator, and selecting those curves which most nearly coincide over the required range. The values' of the elements of the excess-simulator are then determined from the specific values of the parameters obtained. Figs. 11<c> and 11<d> show networks equivalent to those of Figs. 11<a> and 11<b>. At very low frequencies, the sending end impedance of a line is affected by the distant terminating impedance. The simulating network is then modified by shunting the excess-simulator by a resistance S' approximately equal to the zero-frequency sending-end resistance diminished by R', and this entails slight alteration in the proportioning of the network. The networks of Figs. 14a and 14b are derived from those of Figs. 11<a> and 11<b>, and Figs. 14<c> and 14d show equivalent networks. For lines whose leakance is not quite negligible, this may be taken into account by a slight reproportioning of the network, with the addition of a small series inductance in those cases where the leakance increases rapidly with the frequency.

Title: Improvements relating to adjustable electric standard lamps
IPC: F21V21/26
Filed: 1946-03-25
Abstract: 609,895. Supporting electric lamps. CORNERCROFT, Ltd., and RYCROFT, N. March 25, 1946, No. 9063. [Class 75(iii)] [Also in Group XIV] In an adjustable standard lamp having an adjustable arm 8 and spring counterbalancing means, the upper spring anchorage point is carried by means which is movably mounted relatively to the arm 8 to obtain accurate counterbalancing. The spring 11, Fig. 1, may be attached to a wire hook pivoted at 10b to a box structure 10 sliding in the arm 8 and having a tapped hole to receive a screw 12 sliding in a slot in the top of the arm 8 so that the relative positions of the pivot 10b and 'the pivot 9 of the arm 8 may be adjusted. Alternatively two springs may act on hooks 15, Fig. 4, depending from a plate 16 pivoted at 16a to a box structure 17 sliding in the arm 8 which also contains a sheet metal pressing 18. The pressing 18 may have an ear piece 18a to receive a micrometer screw 19 which engages in an ear piece 17a of the structure 17, adjustment of the screw 19 serving to move the structure 17 relatively to the pressing 18 so that the relative positions of the pivot 16a and the pivot 9 of the arm 8 may be adjusted. Ear pieces 14a, 14b, Fig. 1, on a sheet metal pressing 14 or the ear pieces 17a, 18a, Fig. 4, serve to limit the angular movement of the arm 8 in a slot 7b of the standard 7, and the arm 8 may be mounted in bearings formed between the inwardly pressed part of a structure which is a force fit in the standard 7. The means for adjusting the counterbalancing springs may be applied to a lamp having a non-adjustable standard as described in Specification 609,894 or to one having an adjustable standard as described in Specification 537,194, [Group XIV].

Title: Heat transfer method and apparatus
IPC: F28D7/16
Filed: 1956-03-23
Abstract: 798,708. Tubular heat exchangers. UNITED AIRCRAFT PRODUCTS, Inc. March 23, 1956 [March 25, 1955], No. 9183/56. Class 64(3) Relates to heat exchangers in which a non-congealable fluid passes through parallel heat exchange tubes and is thereby heated by a congealable liquid flowing over the tubes. According to the invention the means are provided to increase the rate of heat transfer between the fluid and the liquid in one part of the heat exchanger as compared with the rate of heat transfer in another part of the heat exchanger. Fig. 1 shows an oil cooler in which the oil is directed by baffles 24, 25 in a sinuous path over a bundle of tubes 16 in a direction counterflow to engine fuel flowing through the tubes. At the oil outlet end of the heat exchanger where the fuel is cold and there is a danger of the cooled oil congealing on the tube surfaces, the tubes 16 are plain and the rate of heat transfer is consequently lower than at the other end of the heat exchanger where the oil and fuel are relatively warm and where an increased rate of heat transfer is maintained by providing in the tube walls spaced annular recesses 26 (see Fig. 2) which constitute flow restrictors causing turbulence and changes of velocity in the fuel as it passes through the tubes. The rate of changed heat transfer in one part of the heat exchanger as compared with another may be made progressive e.g. by progressively decreasing the spacing and/or the depth of the recesses 26. Valve means (not shown) may be provided for controlling the flow of engine oil or fuel or both in order that the fuel temperature may remain constant. Specification 766,614 is referred to.

Title: Improvements in or relating to electric switchgear
IPC: H02B1/00
Filed: 1926-04-08
Abstract: 274,171. Reyrolle & Co., Ltd., A., Anderson, W., and Mirrey, J. April 8, 1926. Oil switches; sliding switch-carriage arrangements.-In electric switchgear of the draw-out type, two sets of plugs on the draw-out portion normally co-operate with corresponding fixed sockets, and the plugs of one set are slidable longitudinally in their mountings into positions in which each makes connection between an .earthed contact and one pole of a circuit-breaker. With the slidable plugs so withdrawn, closing of the circuit-breakers will complete an earthing connection to the other plugs and the corresponding sockets. The switch gear shown, for use with three-phase circuits, comprises six plugs D, E, corresponding sockets A', A<2>, and three circuit-breakers C. Each plug D is slidable with respect to the draw-out portion B, and carries a contact piece D<1> engaging a conducting sleeve C' connected to the pole C<2> of a circuit-breaker C. 'When the plug D is in the position shown in Fig. 1, the gap between the socket A<1> and sleeve C<3> is bridged. An insulating stem D<2>, secured to the plug D, carries a pin D<3> engaging slots F<1>, F<2> and G<1>, G<2> in telescopically arranged conducting tubes F, G, the tube F being fixed and G slidable. When in the position shown in Fig. 7, with the tubes G drawn forward, the contact piece D<1> bridges the gap between the sleeve C<3> and the tube F, and, since the tube F is connected to the casing B<2>, earths the pole C<2> of the contact breaker. When in this position, the tubes G may be simultaneously rotated through 45‹ by the lever K<3> and cams K<1>, and then pushed in to their original longitudinal position without disturbing the plugs D, the slots G' sliding along the pins D<3> which are themselves prevented from backward movement by the cam pins K. In order to pull forward the tubes G, nuts M are provided, engaging bolts M<1> and being provided with collars M<2> which bear against the back of the plate L to which the tubes G are secured. After the nuts M have been completely removed from the bolts M<1>, the forward movement of the tubes G may be completed by pulling on the handle L<1>. An interlock M<3>, O, 0', O<2>, N<2>, P is provided to prevent the plugs D from bein withdrawn from the sockets A<1> unless the circuit-breakers are open. A second interlock, N, N<2>, N<3>, K<4> prevents the circuit-breakers from being closed except when the nuts M are fully screwed home, and the plugs D are in one or other of their two definite positions, i.e. the earthing position or the operative position, and renders it impossible to rotate the tubes G and cams K<1> except when the front plate has been withdrawn to its most forward position. When the circuit-breakers are provided with a low-volt tripping mechanism, Fig. 6, a Bowden wire Q may be provided, actuated by the coupling rod K<2>, to render the mechanism inoperative when the slidable plugs are in their earthing positions.

Title: Improvements in methods of and apparatus for formnig tubular films of synthetic thermoplastic organic material
IPC: B29C48/03
Filed: 1961-03-14
Abstract: Tubular films of synthetic organic thermoplastic material are produced by extruding the heated material through an annular extrusion orifice to form a tubular film, drawing the film over a hollow mandrel in air-sealing relation therewith and thence over driven haul-off nip rolls to form a first enclosed air space between the mandrel and the die and a second enclosed air space between the rolls and the mandrel, and passing a coolant through the mandrel to cool the film while maintaining air flow between the first and second spaces so that the pressures in them remain approximately equal.  As shown in Fig. 1, hot thermoplastic material 12 is forced by the worm 13 from the supply vessel 14 through the chamber 11 of the die 10 and out of the annular die orifice 15 to form a tubular film 16.  The tubular film 16 is pulled <PICT:0926843/IV(a)/1> over a hollow mandrel 17 and spreader arms 30 by driven nip rolls 33, 34 and is wound upon a core 35.  The mandrel 17 has rounded shoulders 28 and is suspended from the die 10 by a tube 18 provided with holes 22 for supplying a cooling liquid to the interior of the mandrel and with a smaller coaxial tube 19 having a liquid outlet connection 20. Cooling liquid supplied through the inlet 21 flows down through the space 23 between the tubes 18 and 19 and into the mandrel through the holes 22 in the pipe 18. The cooling liquid flows out of the mandrel 17 through the ports 27 in the hollow plug 24 and up the pipe 19 to the outlet 20.  The space 36 within the portion of the tubular film 16 extending between the mandrel and the die and the space 37 within the portion of the film extending between the mandrel and the nip rolls as in free communication with one another through the pipe 38 extending through the mandrel.  The pressure in the two spaces being thereby equalized.  The pressure in the spaces 36 and 37 may be maintained at atmospheric pressure by removing the threaded plug 40 from the top of the passage 39 in the die 10, but the spaces 36 and 37 are preferably cut off from communication with the atmosphere.

Patent GB-552886-A (GB)
Title: Improvements in and relating to electric motor control systems
IPC: H02P5/685
Filed: 1941-07-24
Abstract: 552,886. Master control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. July 24, 1941, No. 9394. Convention date, July 24, 1940. [Class 38 (iii)] Multiple unit control is arranged so that when the controller D on the leading vehicle is placed in its " coasting position, all motors are connected in braking loops, and when the controller D is in a motoring position, none of the units can start motoring unless the braking loops of all units are opened and unless all units are connected for the same direction of movement. During operation, switch 124 is closed on to contact 138. Field reversing switches are associated with a drum switch R, and only when drum R corresponds in position with a selector switch S, and when a braking contactor B has dropped out, is a circuit completed over S, R, and contacts 98 on B for a correct order relay COR. When all the relays COR of the various units close their contacts 99 in series in a train wire, then a relay CR on the driving unit lifts and permits the controller D to energize a train wire 12 to which is connected on each unit the operating coils 144 of a line breaker LB1 ; this circuit is over contacts 145 of a contactor LC normally always up and contacts 146 of a potential relay PR energized from trolley 40. Before relay COR lifts, its contacts 131 energize a lifting coil 130 of an indicating relay IR which lights an indicating lamp 134 and holds up on coil 133 until line breaker LB1 lifts. If the relay COR of any unit fails to lift, momentary depression of button 140, with the controller D in a motoring or coasting position, causes coil 64 to lift the relay COR and latch it up and to open its contacts 94 and so cause the contactor LC to drop and open the circuit of the motors. Acceleration is effected by an oil motor KM, as in Specification 537,739, cutting out a resistor 39 from right to left whereupon a transfer switch TS lifts and the resistor 39 is again cut out from left to right, anally the fields of the motors are shunted. Motion of the oil motor KM is retarded by the action of a vibrating " acceleration and braking relay ABR. In the " full run " position of the controller D, the bias on the relay ABR is increased to give a greater acceleration. During coasting, a field flashing circuit, and a braking loop are completed by the lifting of contactor B and the motor KM adjusts the current in the loop to a low valve, as in Specifications 513,114 and 514,263. In a "braking" position of the controller D, a resistor 180 is inserted in circuit with the actuating coil of relay ABR, and motor KM adjust resistor 39 to pass a braking current. " Full braking " position of controller D increases the bias on the relay ABR. Whilst the speed is high on voltage limit relay VLR controls the oil motor KM. The various control circuits are supplied from a battery V, some through a latched switch CC, but the coil of contactor LC is direct on the battery, and in series with a resistor L to limit current drain on battery in the event of a short circuit.
