Abstract: 702,941. Control of A.C. motors. ENGLISH ELECTRIC CO., Ltd. June 6, 1952 [June 15, 1951], No. 14218/51. Class 38(3) An electrically propelled vehicle includes, in combination, driving means consisting of at least one single phase commutator motor 1-4; a transformer 5 for supplying current to the driving means, the secondary winding of the transformer being divided into at least two sections one of which is provided with a plurality of tappings, and switch means arranged to be operated in the following sequence so as to accelerate the vehicle:- a) to select tapping points on the secondary winding of increasing voltage b) to select a low voltage tapping on the transformer c) to insert an untapped section of the secondary winding in the circuit, and d) to again select tapping points of increasing voltage, and so on until the whole of the secondary winding is in circuit with the driving means. In the OFF position contactors 12, 19 only are closed. The selection of the increasing voltage tapping points is effected by the cam-shaft operated contactors 12-16 and 18, alternate tappings being connected to opposite ends of an impedance 17 which ensures that, when changing from one contactor to another, the supply is not removed from the motors. Contactor 18 is alternately closed and opened so as to avoid short-circuiting a part of the secondary winding when two adjacent contactors are closed at the same time. When inserting an untapped section into circuit-say the section between taps 5a and 5b-contactor 21 is first closed so that the section is brought into circuit with a resistor 24 in series to limit the current. Contactor 20 is then closed and contactor 21 opened to thereafter remove the resistor. Contactors 22, 23 are similarly operated. Reversing and overload devices are also provided.

Patent GB-560792-A (GB)
Title: Improvements in or relating to gearing for steering mechanically propelled vehicles and for other purposes
IPC: B62D3/10
Filed: 1942-10-15
Abstract: 560,792. Cam mechanism. JOHNSTON, R. H. Oct. 15, 1942, No. 14441. [Class 80 (iii)] Relates to gearing, particularly for steering vehicles, of the type comprising a cam constituted of a worm on an operating shaft engaged by a follower at right angles thereto and mounted on a rocker arm movable in a plane substantially parallel to the axis of the worm the cam groove of which varies in depth throughout its length due to its having been produced by moving the cam blank and cutting tool relatively to each other as described in Specification 223,963, [Class 80 (iii)]. According to the invention, the effective pitch of the cam is substantially constant throughout its length, i.e. equal displacements of the follower in a direction parallel to the axis of the cam are produced by each complete rotation of the cam. This gives a substantially constant efficiency throughout the range of gearing and full reversibility whereby jamming as the locks are approached is prevented. As distinct from the earlier Specification referred to, the cutting tool is so moved that it receives the same linear displacement for each rotation of the cam. The result is that, at points A, A where the axis of the tool lies in a plane passing through the axis of the cam blank, the groove is deepest whereas, at the points B .. B where the axis of the tool is above or below that of the blank, the groove is shallowest.

Filed: 1946-05-15
Abstract: 612,033. Glass manufacture. AKTIESELSKABET MOSS GLASVAERK. May 15, 1946, No. 14743. Convention date, June 4, 1941. [Class 56] In the gathering of molten glass by a dipping suction cup or pre-mould 3, the arm 2 carrying the cup is, together with the machine effecting the dipping, periodically oscillated in a horizontal plane in such a way that the.same spot on the surface of the molten glass is never contacted by two successive dippings. The machine carrying and operating the arm 2 travels along a frame 5 which itself is movable in a horizontal plane about a pivot 7. Oscillation of the frame about this pivot is effected by the engagement of an upwardly pointing stationary spigot with an endless cam track 13 in a drum 11 carried by the frame 5 and constantly rotated, about a horizontal axis, for example by the same motor which drives the dipping machine. The transmission between the motor and the drum 11 includes a chain wheel 16 slidable along a shaft 17 carried in the frame 5 so as to allow movement of the dipping machine along the frame 5. The cam is so designed that the cup dips alternately at each of two positions.

Abstract: 726,930. Feeding sheets. GERICKE, E. June 11, 1952 [Oct. 5, 1951], No. 14753/52. Class 100 (1). Pile tables and supports; sheet separators.- A device for the automatic separation of the uppermost sheet of paper from a pile, in which, at the front edge of the pile, one or more hooks are provided which resiliently press the uppermost sheet on to the pile, and over which the sheet is pushed forwardly by a suction device after it has been separated from the hooks by movement in a rearward direction, is characterized in that prior to the rearward separation of the uppermost sheet the hooks are raised, and before the start of the subsequent movement of the sheet are again returned to the pile so that the sheet can be slidingly moved over the hooks. As shown, an inclined pile of sheets 1 rests with its front edge against a pile wall 2, suckers 3 being provided for grasping the uppermost sheet and pulling it back from beneath the hooks 5 in the direction of the arrow R. The hooks are raised to release the sheet by means of a cam disc 7 which operates a lever having arms 11, 24 and 13, the arm 24 being adapted to engage a projection 23 of the hooks 5 to raise it against the action of a spring 6. As soon as the sucker has removed the top sheet 4 the hooks 5 are lowered and feeding in the direction of the arrow V, to grippers 19, takes place. The height of the pile is maintained at a constant level by a pawl and ratchet mechanism 10 operated by the action of a lever 9 and cam 8. When the pile is at a correct level the action of the pawl mechanism 10 is suspended by the engagement of the arm 13 with a stop 22 on the lever 9. As soon as the height of the pile 1 has become low enough for a projection 12 fixed on the hook 5 to prevent the lever carrying the arms 11 from following the cam 7, the arm 13 is held away from the stop 22, thereby allowing the lever 9 to follow the cam 8 and raise the pile step-by-step until the projection 12 is again disengaged from the arm 11.
