Title: Improvements in or relating to Automatic Weighing Scales.
Inventor: WHITE ALFRED ERNEST
IPC: G01G1/00
Filed: 1917-12-14
Abstract: 121,995. White, A. E., (Toledo Scale Co.). Dec. 14, 1917. Pendulum-weight apparatus; indicating-mechanism. - In a weighing.scale of the gravity type provided with automatic indicating - mechanism, oppositely-disposed weight-supporting members are arranged conjointly to suspend a single element constituting a load-balancing weight which is free to swing laterally with respect to the central vertical line of the scale without disturbing the accuracy of the indicating- mechanism. As shown, the weight-supporting members 19, Fig. 1, are rocker segments secured to shafts pivotally mounted at the ends of bars 14 in such a manner as to constitute with the bars a flexible frame, and flexible metal ribbons 21 are secured at 20 to the segments and support an equalizer bar 22 to which loadbalancing weights 23 are adjustably secured. Rocker segments 9, 15 also are secured to the pivoted shafts and are connected by flexible metal ribbons 10, 17 respectively to fixed points 12 on the supporting-frame 7, 8 and to an equal. izer bar 18, which is provided with a pivoted link 24 connected by a hooked bar 25 to the levers supporting the scale platform, the bar 25 preferably passing through a slot 22<a> in the bar 22. A central bar 30 is pivotally mounted in openings in the bars 14, and is connected by a resilient member 29 to a vertical rack 28 in gear with a pinion 31 on the journal of the indicator hand 26, which adjacent to its pivot is expanded into a plate with slots 32 for adjustable counterbalancing weights. When a load is placed on the platform, the rib. bons 17, 21 are unwound from and wound on their respective segments 15. 19, and the segments 9 move upwards along the ribbons 10 raising the flexible frame, the weights 23, and the central bar 30, so that the rack 28 also is raised and the hand 26 is moved round the indicator dial 27. In order that the indications on the dial may be equally spaced for equal movements of weight, the bearing-surfaces of the segments may be suitably shaped; thus the surfaces of the segments 15 are shown in the form of spiral cams for this purpose. The segments 15, 19 are adjustable on their shaft relatively to one another by screws 34, Fig. 4, threaded in the frame of the segment 15 and acting on a radial lug 33 on the segment 19, slots 40 being provided in the hubs to permit of the relative turning movement and lock-nuts 35 being provided. If the scale is tilted out of the level position, the ribbons 21 are wound on and unwound from their respective segment, the lifting of one end of the bar 22 is compensated for by the corresponding falling of the other end, and a corresponding lifting and lowering of the ends of the bars 14 is effected; also, twisting of the flexible frame is permitted without affecting the free rocking of the segments. The mechanism may be used with various forms of scale, such as dormant, portable, or hanging scales.

Title: Improvements in or relating to induction motors
Inventor: RAWCLIFFE GORDON HINDLE
IPC: H02K17/14
Filed: 1955-06-30
Abstract: 797,290. Winding layouts for induction motors. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 18, 1956 [June 30, 1955], No. 19001/55. Class 35. Seventh-harmonic " crawl " is avoided in a 3-1 pole-changing induction motor by making each of the three-phase windings of 120 degrees phase-spread, divided into three 40 degree sections, and connectable in delta with one of the 40 degree sections omitted in each phase, or in triple-pole-number star using all the sections. Thus in the high-speed connection the phasespread is 80 degrees while in the low-speed connection the phase-spread is 120 degrees. The connections to the 40 degrees winding sections 1, 2, 3 of the three phases A, B, C are shown for the high and low speeds, respectively, in Figs. 4a, 4b, the leads which are brought out to the change-pole switch being numbered 1-11. A detailed layout of windings is given. If desired, the middle 40 degree section may be omitted at the high-speed instead of the end section. The rotor may be of squirrel-cage type with skewed slots, or a two-phase wound'rotor having six phase-bands connected into two groups of three in parallel, may be used, the bands in each group being spaced at 120 degrees. At the small pole-number each group is thus short-circuited, while at the high pole-number, the spacing is effectively 360 degrees so that the voltages of the group are in addition and may be applied to a starting resistance through sliprings. The two groups are placed in quadrature to give two-phase operation of the rotor.

Abstract: 934,157. Perforating; assembling force fits; riveted joints. BELLING & LEE Ltd. June 15, 1962 [May 26, 1961], No. 19078/61. Class 83 (4). [Also in Group XXV] A method of securing a rigid insert in a rigid sheet of material includes the steps of contacting a serrated leading edge of the insert with one face of the material, positioning a die with a non-serrated cutting edge on the other face of the material and applying pressure to the insert so that a piece of material is sheared from the sheet and at least a serrated part of the insert following the leading face is forced into the place of the sheared piece of material. The insert comprises a cylindrical threaded shank 1 and a larger portion 3 which is knurled at 4 and 5 and has a groove 7 linked to the knurl 4 by a chamfer 8. The insert is secured in a sheet of material by  the apparatus shown in Fig. 2 which comprises a punch 11 and a die 15 which has a bore 16 'equal in diameter to the circle 21 (Fig. 3) through the mid-points of the knurl teeth 20. A ring 17 projects above the surface of the die and is joined to the bore 16 by a chamfer 18. The insert co-operates with the die to perforate the material 9, and the insert is then forced into the hole until the lower face of the punch contacts the surface 12 of the material. Further pressure is applied and the ring 17 forces material of the sheet 9 into the groove 7. Since the bore of the die is smaller than the major diameter of the knurl 5, the tips of the knurl teeth are peened over as shown at 24 and further secure the insert. Specifications 776,373, 869,037 and 911,037 are referred to.

Fibres of glass or other vitreous material, cotton, rayon or nylon, in the form of single or multi-strands, tapes or ribbons, are helically coiled on a rotary and axially-movable former a which is intermittently retracted relatively to the material coiled thereon to enable a tubular body to be made in a step-by-step manner. As shown, the former a is secured to a rotary part e supported in a carriage g, slidably mounted on guide-rods h, and carrying a gear-wheel f driven through an intermediate idling pinion i by a pinion slidable on a shaft k which is rotated by an electric motor m and through belt and chain drives n, o. Axial forward movement of the former a is effected by a chain p carried on sprockets q and secured to the carriage g, one of the sprockets being driven by a shaft r engageable with a coaxial shaft s through a clutch t. The shaft a is driven by a belt w and through a worm.wheel and worm u, v. The former a is retracted by a fluid-operated ram x attached to the carriage g and extending from a cylinder y, and is supported at an intermediate position by a stationary plate b carried on a frame c mounted on the bed d of the machine. When the former a is retracted the end of the inner layer of coiled material on the former is brought into contact with the plate b so that the former a moves towards the starting position thereof and relatively to the tubular body. After each retractive movement of the former the coils of the tubular body are moved out of contact with the plate b by a spring in a gland 7, the spring being compressed by the carriage g and moving the carriage forward at the end of the retractive movement. The material passes through baths 3 of liquid bonding material, e.g. a polyester, which is hardened by heat derived from steam conveyed by a pipe 4 to the interior of the former a ; alternatively, the material is precoated by a bonding substance, such as a polyester or formaldehyde, which is allowed to dry before the material is coiled but which is subsequently hardened. More than one layer of material may be applied to the former and there may be at least one layer of filaments 13 extending longitudinally between the helically coiled layers and supplied from a number of reels carried on a plate 12 rotated from the shaft k, the rate of rotation of the plate being such that the filaments 13 are deposited parallel with or inclined to the axis of the tubular body. An outer covering 16 of helically coiled ribbon or tape, e.g. " Cellophane " (Registered Trade Mark), is applied to the body. According to the Provisional Specification, the former a extends and advances horizontally from a gear-box.
