Filed: 1937-05-19
Abstract: 481,345. Electric signalling systems. BRITISH THOMSON - HOUSTON CO., Ltd. May 19, 1937, No. 13974. Convenion date, May 20, 1936. [Class 40 (i)] [Also in Group XXXV] A telemeter receiver of the resultant field type comprises a toroidal field winding 18 wound on a core 30 of low-hysteresis magnetic material and a cylindrical armature 19 which is transversely magnetized and consists of sintered magnetite, ferric oxide and cobaltic oxide. A damping ring 29 is interposed between 'the field and armature. In modifications, the field winding may consist of three concentrated windings on the core 30, or three coils with or without magnetic cores having radial axes. As shown the receiver is controlled by a tapped rheostat 15 having adjustable brushes 16 fed from a battery 17. In a modified transmitter, a pair of contacts arranged for straight line action is movable over a pair of straight resistances which are interconnected and tapped to provide a three-phase output. A similar arrangement for limited rotary motion may be provided in order that small movements of the transmitter may produce large movements of the receiver.

As shown in Fig. 5, the loudspeaker 41 excites two resonating pipes 42, 43 one tuned to the first harmonic of the other. Rotatable vanes or shutters may be provided in the pipes to obtain "vibrato" effects. The Specification as open to inspection under Sect. 91 describes modifications in which the pedals 19, 20 control the emission of the soundboards by means of shutters instead of or in addition to the potentiometer control. This subject-matter does not appear in the Specification as accepted.

Filed: 1955-05-16
Abstract: 795,673. Propelling sail vehicles. MITCHELL, F. G. May 16, 1956 [May 16, 1955], No. 14044/55. Class 104 (2). A vehicle handling mule comprises a carriage running on tracks within standard gauge rail tracks and having a pusher assembly movable between an inoperative lowered position within the width of the carriage and a raised operative position outside the width of the carriage to engage the buffers or other laterally spaced parts of the body of the vehicle to be moved. As shown in Fig. 1, arms 5 mounted on transverse inclined pivots 6 are raised to the operative position by links 7 connected to the arms 5 and to a block 22 displaceable along a screwed rod 24 by rotating the rod by means of a reversible motor 28 mounted on the carriage. In another arrangement, Fig. 3 (not shown), the block is secured to a rod and the arms are raised by tensioning the rear end of a carriage traction cable 12 which is secured to the rear end of the rod. The arms are lowered by a spring when the tension is released. In the form shown in Figs. 2 and 5, the arms pivot on two blocks 32, 33 slidable along two rods 34 on the carriage. The blocks are interconnected by a pivot 39 which passes through the stem 37 of a T-shaped abutment maintained vertical by rollers 41 guided below tracks 42 on the carriage. The arms are raised by forward movement of the carriage causing the abutment stem 37 to strike a track stop 38 and displace the blocks backwards along the rods until they contact a carriage stop 43 where the arms are fully raised and the abutment then pivots to pass over the track stop 38. The arms are lowered by backward movement of the carriage over another track stop.

Abstract: 495,840. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. May 21, 1937, No. 14212. Convention date, May 21, 1936. [Class 38 (iii)] In a system for starting a synchronous motor 1 with its field 3 connected to a resistance 6, in which, as described in Specification 384,567, the energization of the field is effected under the control of a relay 11 energized from the resistance 6 through a rectifier 10, a condenser 16 is connected in parallel with the rectifier 10 whereby the current in the coil of the relay 11 falls to zero before the current in the field winding. Thus the operation of the field switch 9, in response to the relay 11, takes place at the most favourable point in the cycle of induced field current. The Specification as open to inspection under Sect. 91 comprises also an arrangement in which an additional rectifier is connected across the coil of the relay 11 in opposition to the rectifier 10. This subject-matter does not appear in the Specification as accepted.

Abstract: 356,785. Vaporizers. PETITPAS, E. D., Clery-les-Andelys, Eure, France. May 12, 1930, No. 14555. Convention date, Jan. 8. [Class 7 (iii).] In a vaporizer for heavy oils the volume of the vaporizing chamber is made equal to the cylinder capacity of the engine. A condensing trap is provided in the induction pipe to collect unvaporized fuel. As applied to stationary engines the heavy oil mixture from a carburetter enters a vaporizing chamber 5 through a port 6<1> and leaves through a port 7<1>. Exhaust gases enter at 3 a pipe 4, closed at one end, which traverses the chamber 5. Pipes 15 arranged radially extend through the pipe 5 and allow the exhaust to escape to a chamber 1 and an outlet 14 through orifices 16. At starting, when a petrol carburetter is used, a valve 12 closes the pipe 4 to prevent the exhaust gases from entering the chamber. A condensing trap 9, Fig. 5, includes a baffle 18 and drainage means, and is attached to the port 7<1>, Fig. 3, leading to the intake manifold. A tube 19 allows deposits to be drained from the vaporizing chamber into the trap 9. A single carburetter is used for both fuels. As applied to motor-car engines two carburetters 25, 26, Fig. 6, for petrol and heavy oil respectively and a rotary valve 27 are used, and the mixture from the petrol carburetter does not pass through the vaporizer. The condensate trap is placed between the valve 27 and the engine. The petrol and heavy oil carburetters are simultaneously controlled by a rod 34 connecting the controls 33, 35, the latter being connected to the governor of the engine by a rod 38.

Abstract: 567,931. Discharging coke ovens. COLVILLES, Ltd., and TODD, D. Sept. 7, 1943, No. 14683. [Class 51 (ii)] [Also in Group XXXVII] In coke oven plant having a discharging ram and a coke guide movable along opposite sides of the oven battery, the coke guide carries a contact member connected electrically to the ram-operating system in such a manner that, if the guide is subjected, due to incorrect positioning, to impact by the coke being discharged, the contact member is displaced and operates a switch to cut off the power to the ram. As shown, the contact member comprises an inverted pendulum 1 having an arbor 25 and a weight 26 at its upper end, the device being adapted to be set, by the coke guide operator, in an unstable position in which it rests against a stop 29 and from which, if the guide is incorrectly positioned ,and is fouled by the coke, it is displaced to the stable position shown in dotted lines. In the unstable position, the member 1 closes a switch to make power available for the ram and opens a switch in a circuit supplying power to the guide machine, thus rendering further movement thereof impossible, while when displaced to the stable position, it operates a switch to cut off the power to the ram. The electric circuits are described in detail and include a circuit, controlled by a switch actuated manually by the guide machine operator, for energizing a signal lamp on the ram machine to indicate that all is in readiness for the ramming operation and that power therefor is available.
