Title: Improvements in or relating to spring mechanisms
IPC: A43D21/12
Filed: 1938-11-14
Abstract: 521,393. Spring mechanism. UNITED SHOE MACHINERY CORPORATION. Nov. 14, 1938, No. 33003. Convention date, Nov. 15, 1937. [Class 108 (iii)] A spring mechanism comprises a movable member, a pair of springs of different strengths arranged to be subjected to stress on movement of the said member, and means for rendering either of the springs idle while the other is subjected to stress. In the construction shown the disc 60 is movable to stress the two coaxial coil springs 44, 46 and cause movement of the slide 12. A rod 36 is secured at its front end to the slide, and mounted on this rod is the sleeve 38 which abuts against the slide. The springs 44, 46 abut at their front ends against the washer 42 which is held in place by the nuts 40 threaded on the sleeve 38, and at their other ends against rings 48, 50, respectively. The rings 48, 50 each carry a set of three pins 52, 54, Fig. 3, which extend slidably through a flange 56 on the sleeve 38. The disc 60 is slidably mounted on a sleeve 64 on the rear end of the rod 36 and is moved by a bell-crank lever 70 through links 68. The pins 66 connecting the disc 60 to the links 68 carry rolls 88 which are movable along guideways to support the rod 36 and prevent rotation of the disc 60. A set of three holes 58 in the disc register with the pins 52 when the sleeve 38 is rotated to the appropriate position. The pins 52 thus enter the holes 58 when the disc 60 is moved and the spring 44 is left idle while the spring 46 is stressed. In another position of the sleeve 38 the pins 54 register with the holes 62 and the spring 46 is idle while the spring 44 is stressed. In a third position of the slide neither set of pins registers with the holes and both springs are stressed. The sleeve 38 is rotated by lateral movement of the rack bar 96, Fig. 3, which meshes with the gear sector 94 integral with the sleeve.

Abstract: 763,460. Cycle speedometer drive mountings. SMITH & SONS (ENGLAND), Ltd. S. Feb. 17, 1955 [Nov. 27, 1953], No. 33022/53. Class 106 (3). A housing for a speedometer drive comprises a housing in the form of an annular 1 carrying a ring-shaped gear with helical teeth driven by means of an arm 3 engaging the spokes of the wheel and engaging with a pinion in a tengential cylindrical portion connecting with the flexible drive. The annular 1 has a flange 6 whose opposite faces engage with flanges 13, 14 of two cup-shaped members 9, 10 made of resilient sheet steel, the first member 9 having an internal diameter equal to that of the inside edge of the flange 6 and the second member 10 having an external diameter rather less than that of the inside edge of the flange 6 and a depth rather less than the depth of the first member plus the thickness of the flange 6. The cup of the second member fits inside that of the first and each is provided with a central hole 20 taking over the wheel spindle 21 on which the whole mounting is retained by the usual fork nut 23. - The housing 1 may be located relatively to the cup members 9, 10 by a notch and dowel arrangement. The depth of' the cups 9, 10 is varied to suit the particular hub and fork arrangement of the cycle for which it is designed.

Title: Improvements in or relating to coin-freed vending apparatus
IPC: G07F11/48
Filed: 1928-11-12
Abstract: 324,151. Gonyk, I. Nov. 12, 1928. Stream - cutting machines. - A magazine 5 containing a bar of material, such as soap, is rocked about a headed bolt 9, against the action of a spring 12 bearing on an arm 10, to cause the lower part 6 of the magazine to enter a casing 40 containing coin-freed mechanism. The bar is supported on a curved guiding surface 4 forming the top of a delivery scoop 17, the side walls 6<1> of the part 6 enclosing the edge of the plate 4. When the magazine is rocked inwardly, a portion of the bar is cut off by a knife 15 having an undulating surface, and drops through an aperture 16 in the plate 4 to the scoop 17. The magazine is normally prevented from rocking by a small weight 20 obstructing the entrance to the casing 40, and suspended by an arm 21 from a balance lever 22. After the insertion of a coin the weight 20 is raised.

Title: Improvements in and relating to vapour electric discharge devices
IPC: H01J17/04
Filed: 1929-10-31
Abstract: 341,995. Automatic regulation. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Winter, W. F. ; 1013, Garner Avenue, Schenectady, New York, U.S.A.) Oct. 31, 1929, No. 33098. Convention date, Oct. 31, 1928. [Class 38 (iv).] An electric discharge tube, provided with a mechanical valve 18, Fig. 1, to control the discharge by obturation, is adapted to maintain a constant current through a load 27 from a source 26. The effective opening of the valve is controlled by a solenoid 24 which is connected in series with the load and tube and opposes the action of a biasing solenoid 25 which is connected to a separate current source. To start the arc, a temporary positive potential is applied to the valve 18 through a switch 30 and a resistance 31, while the valve is opened by energizing the solenoid 25 through a switch 29. To prevent re-ignition in the event of the discharge being interrupted, a negative bias is imposed on the valve through a switch 32. In a modification, Fig. 3, the tube acts as a constant-current regulator for a motor M. A grid 41 is connected to the valve 18 through the secondary of a transformer 40, the primary of which is connected in series with the load. A sudden overload closes the valve and causes a negative bias upon the valve to extinguish the arc. For starting purposes, a positive potential is applied to the grid 41 and the valve 18 by a battery 38 through a push-button 39, which when released connects contacts 46 and results in a negative potential thereon. Specification 165,217, [Class 39 (i), Electric lamps, Arc &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes a tube for use with alternating currents (cancelled Fig. 3 not shown). This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the production of blown films from soft polyvinyl chloride
Inventor: ROHLIG GUNTER
IPC: B29C48/10
Filed: 1962-08-29
Abstract: 967,881. Tubular films. BARMER MASCHINENFABRIK A.G. Aug. 29, 1962, No. 33198/62. Heading B5B. In making tubular films, a mixture in powder form of polyvinyl chloride and more than 20% by weight of plasticizer (calculated on the mixture) is supplied to the entrance of an extruder, consolidated and melted in one or more zones, passed as a melt through an externally heated homogenization zone, deflected from horizontal to vertical direction and extruded as a tube which is then expanded. The homogenization zone comprises a worm, the depth of the recessed portions of which is 3-8% of the outer diameter of the worm, the length of the homogenization zone being at least 10 times the outer diameter of the worm, and at least the length of the entrance zone and consolidation zone together. The melt passing from the homogenization zone may be deflected around a deflector element in the shape of a right-angled rounded isosceles triangle. In one such embodiment (Figs. 1 and 2) a mixture of polyvinyl chloride and plasticizer, after passing through entrance, consolidation and homogenization zones, is deflected from horizontal to vertical in a ring element 1 containing mandrel 4. A recess 7 is formed in the mandrel, so that a triangular deflector element 5 is formed, around which the melt 6 flows. The melt impinging on the recess 7 divides into two streams flowing around the deflector element. The streams unite above the deflector element, and the melt is extruded between mandrel 4 and mouthpiece 2 as a tube. In an example, a mixture of polyvinyl chloride and plasticizer is supplied to a single-worm extruder having compression ratio 1: 4, worm diameter 90 mm. and an effective length of 24 times the diameter. After passing through entrance and consolidation zones, the melt is passed through a homogenization zone of length 12 times the worm diameter and a pitch depth (depth of recessed portions) of 3.2-3.5 mm. The melt is then deflected from horizontal to vertical and extruded through an annular nozzle of 250 mm. diameter.
