Title: Method of and apparatus for the surface hardening of gear wheels
IPC: C21D9/32
Filed: 1963-01-10
Abstract: <PICT:1022857/C6-C7/1> A method of hardening a gear wheel comprises rotating the gear wheel within an inductor having effective sections set at an angle less than 90 degrees to the axis of the inductor and extending across at least the width of the gear wheel and electro-inductively heating the rotating wheel by heat applied essentially in peripheral zones by the sections, and immediately quenching the gear wheel when sufficiently heated.  As shown, the gear wheel 1 with tooth crests 2 is encircled by an inductor having effective sections 3, 4 set at an angle 5 to the axis of the inductor and consequently to the direction of the crests of the teeth. Further embodiments of inductors are described (see Division H5). The angle 5 and the size of the inductor sections depends upon the size of the teeth.

Title: Improvements in or relating to vehicles for cleaning streets, parks and the like
IPC: E01H1/04
Filed: 1968-01-09
Abstract: 1,219,121. Motor vehicles; vehicle suspension. LELY - DECHENTREITER MASCHINENFABRIK G.m.b.H. 9 Jan., 1968 [19 Jan., 1967], No. 1353/68. Headings B7D and B7H. In a street or park cleaning machine refuse is picked up by rotary tines 68 ahead of the front wheels 13, thrown on to a conveyer 66, and pushed by orbital tines 44 through a closable opening 49 in the front wall of a trough 59, the trough having a movable floor formed by conveyer chains 57 for packing and off-loading the refuse. The orbital tines 44 pass between a row of fixed strips 50 and depend from a planetary support 43 carried between coaxial gear-wheels 39 and linked to fixed supports 47 whereby the tines 44 are moved along orbital path 5. The rotary tines 58 pass between a row of curved brackets 7 and are mounted on a drum 69 carried by ground wheels 75 and arms 62 having lifting cylinders 77. The front wheels 13, Fig. 2, are geared to individual hydraulic drive motors 21 and are carried by oblique steering pins 11 depending from a raised front axle 9. The vehicle frame is mounted on the front axle by a horizontal pivot 8 and helical springs 37, Fig. 5, and is mounted on the back axle by leaf springs. The rear wheels are driven through continuously variable belt gearing co-operating with a three-speed and reverse gear box coupled with the back axle differential gear. The hydraulic front wheel motors 21 can only be energized when first or reverse gear is engaged. All the mechanisms shown are driven through belt, chain or hydraulic drives from a main engine 33 mounted transversely behind the driver's seat 32. A further seat may be provided behind the engine. A demountable cabin 34 has a forwardly inclined windscreen 35, a lower window 35, and viewing apertures in its floor. The refuse trough 59, formed by a front wall 26 and low side walls, has a dismantable cover 79, Fig. 7, provided with side walls and a top-hinged tail grid or door 80, and is supported on the vehicle frame by spring-loaded hydraulic screw jacks 81. The cover is demounted by (a) raising it on the jacks 81; (b) securing temporary ground-support struts 84 to its side walls; (c) retracting the jacks; and (d) driving the vehicle away.

Title: Improvements in or relating to electromagnetic deflecting coils or electric transformer coils
IPC: H01F17/00
Filed: 1955-01-17
Abstract: 795,469. Transformers. CENTRE D'ETUDE ET DE DEVELOPPEMENTS DE L'ELECTRONIQUE CEDEL. Jan. 17, 1955 [Jan. 15, 1954], No. 1431/55. Class 38 (2). [Also in Group XL (a)] A winding such as a winding for an electric transformer or for the deflection coils of a cathode-ray tube comprises a flexible ribbon of insulating material, on each face 5, 6 of which are printed a series of coil elements, the series on the face 5 being displaced. along the ribbon relatively to the series on the face 6, the coil elements on the face 5 being connected to the coil elements on the face 6 by way of perforations in the ribbon so that the coil elements on the two faces are all series connected; each perforation in the ribbon being in register with an end of a coil element on one face and an end of a coil element on the other face, the ribbon being coiled to form a spiral such that the turns thereof are insulated from one another, thereby to form the winding. The winding is made by a method which includes the steps of perforating a flexible ribbon of insulating material at predetermined intervals, metallizing the edges of the perforations and both sides of the ribbon by the evaporation in vacuo or in a neutral atmosphere of a conducting material, depositing a photo-sensitive film on the conducting material on the two sides of the ribbon, photographing an impression of the coil elements and the edges of the perforations on to the film; removing the unimpressed parts of the conducting material by an engraving process; and increasing the thickness of the conductor of the coil elements by electro deposition processes. When coiling the ribbon to form a spiral insulating material is placed between the turns. In order to take account of the increasing diameter of the spiral as the ribbon is coiled up and to ensure that the superimposed coil elements have the same axis, the succeeding coil elements may be made larger in size or alternatively the succeeding perforations through the strip are made larger.

Abstract: 450,409. Shuttles for circular looms. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and POOL, W., c/o British Celanese, Ltd., Spondon, near Derby. Jan. 16, 1935, No. 1483. [Classes 142 (ii) and 142 (iii)] A shuttle having a rotatably mounted weft spool 10 is provided with a freely movable braking member adapted, on deceleration of the shuttle, to move under the influence of inertia to apply a braking force to the spool. In the construction shown, the braking member comprises a lined shoe 21 carried by a lever 17 that is freely pivoted on the shuttle at 18 and is capable of swinging pendulumwise within the confines of a strap 22, the lower end of the lever carrying a weight 19 which is adjustable or replaceable for varying the braking force. Alternatively the swinging of the lever 17 may bring about the contraction of a brake band on to the spool or the introduction of a wedge between the spool and the shuttle body. When the deceleration ceases the brake automatically moves out of contact with the spool. The spool is retained on its supporting spindle 11 by a spring clip 16. Specification 446,270 is referred to.

Abstract: 1,042,221. Hydraulic jacks. TANGYES Ltd. Dec. 29, 1964 [Jan. 14, 1964], No. 1544/64. Heading B8J. An hydraulic jack comprises a body part having a base portion 10 and a housing member 11 of channel section extending at right angles thereto and a load carrying member 12 with a load-supporting pad 13 and a load-supporting toe 14 received in a recess 15, Fig. 2 (not shown), when the jack is retracted. Within the loadcarrying member 12 is formed a blind bore 21 accommodating a rod 22 secured to the base portion 10 and having a piston head 22a sealed to the bore 21 by a ring 23. The chamber above the piston head 22a receives pressure fluid to extend the jack from a pumping chamber 26 through a one-way valve 25 and a longitudinal passage 24 in the rod 22. A further one-way valve 28 allows fluid to pass from a reservoir 27 to the pumping chamber 26. Upward movement of the load-carrying member 12 is limited by a projection 18 abutting a stop 19. A manually operated valve 29 is provided to allow fluid to flow from the chamber above the piston head 22a to the reservoir 27 to lower the jack. The load-carrying member 12 is guided by ribs 16 sliding in guide slots 17 formed in the housing to resist the imposition of side forces on the rod 22 particularly liable when the toe 14 is used to carry the load. In an alternative construction (not shown) the ribs 16 and guides 17 are omitted and the open side of the upper part of the housing member 11 is closed by a plate to prevent angular movement of the load-carrying member 12.
