Title: Method and apparatus for twisting and plying strands
IPC: D02G3/28
Filed: 1964-08-24
Abstract: 1,019,179. Plying yarn. A. W. VIBBER. Aug. 24,1964, No. 34559/64. Heading D1D. A two-ply strand is formed by feeding a first strand a at a substantially constant speed into a loop 50 rotating about a let-off package 10 of a second strand b which is fed at a substantially constant tension into engagement with the first strand at a fixed plying point X on the axis of the rotating loop, the plied strand c being fed away at a substantially constant speed. In one embodiment strand a passes from capstan set 36, which comprises spaced rollers 37, 39 driven in synchronism with shaft 11 and being inclined to one another, and a spring pressed idle roll 40, to a balloon control device 49 having a bell-shaped metal element 66 which is screw threaded to support 44. When the balloon diameter tends to increase the strand rotates the element 66 to decrease the height of the balloon while when the diameter decreases a spring 71 Fig. 2 (not shown) rotates the element in the opposite direction to increase the height of the balloon. Strand a then passes via flyer disc 51 through a radial passage in shaft 11 to a cord forming die therein. Mounted on the shaft 11 but prevented from rotation therewith by magnets 27, 29, there is a package support 22 and a tension controller 26 having two rolls 27, 28 pressed together by a leaf spring 32, the yarn b passing between the rolls. The plied strand is withdrawn by capstan 54 similar to capstan 36. In a second embodiment. Fig. 3 (not shown) yarn a is supplied from a multiple end beam, there is an auxiliary flier 131 for strand a mounted on top of the package of strand b and having a greater radius than flyer disc 51, and there is a composite capstan 100, Fig. 4 (not shown) for strands a and c and comprising driven rolls 102,119 of different diameters, mounted on a common shaft, and having idle rolls 106, 121 pressed there against, and separate idle rolls 104,120, yarns a and c respectively passing several times around pairs of rolls 102 and 104, and 119 and 120.

Title: Improvements in or relating to the manufacture of elastic fabrics
Filed: 1936-12-16
Abstract: 482,767. Coated fabrics ; compound fabrics. SCHWARTZ, F. F., and CHAVANNES, M. A. Dec. 16, 1936, No. 34622. Convention date, March 21. [Class 140] A porous elastic fabric comprises an extensible fabric base having on one or both sides a foraminous covering of elastic material, such as rubber, adhering substantially only to salient or projecting parts of the fabric surface without connecting the threads at their points of intersection, the covering being applied to the fabric base, while in substantially unstrained condition, as a series of sprayed coatings of rubber &c. latex, each coating being coagulated and dried before the application of the succeeding coating. Multilayer fabrics are produced by securing the layers together by the covering or coverings, e.g. a two-ply fabric is obtained by securing two coated fabrics together with the coated surfaces in contact, or a three-ply fabric may be obtained by interposing a fabric, coated on both sides, between two uncoated fabrics. To promote adhesion the surfaces may be treated with a solvent. In an example, a ribbed, knitted fabric is sprayed, in stages, with rubber latex in droplets of about 0À1-0À3 mm. diameter, the latex being allowed to dry between successive applications. The latex contains a weak electrolyte e.g. ammonium borate which acts as a coagulant at the moment when part of the ammonia is lost by evaporation; alternatively ammonium acetate or an ammoniacal complex of zinc borate, zinc acetate, or another salt of zinc with a weak acid radical, may be employed. The coated fabric is dried, cut into two pieces, the surfaces brushed with benzene and the two surfaces are brought together with the ribs crossing at a suitable angle and united under slight pressure.

Title: Improvements relating to electric lampholders, and shade carriers therefor
IPC: F21V17/06
Filed: 1920-12-09
Abstract: 176,159. Hope, V. Dec. 9, 1920. Mounting shades directly on rods or tubes.- In electric incandescent lamp-holders of the kind described in Specification 152,710, [Class 39 (ii), Electric lamps, Incandescent], wherein the casing is formed in two parts A, B connected together by a bayonet joint a<1>, b<1>, a support for the shade G is provided which prevents accidental separation of the parts A, B. The part A is formed with a flange a<2> against which the shade G is pressed by the flange f of a sleeve F, the screwthread of which is formed as a coarse impression and engages only with a projection b<2> on the part B. The sleeve can thus be aligned on the part B before turning it to screw it up. The projection and the screw thread may be formed on the sleeve and on the part B respectively. Depression of the part A on the part B which is necessary to permit separation of the parts is thus prevented until the sleeve F is lowered.

Title: Improvements in the suspension of vehicles
IPC: B60G21/06
Filed: 1932-12-09
Abstract: 400,012. Vehicle - suspension systems; dashpots. LOMBARD, E., 17, Avenue Jean JaurÞs, Dizy, Marne, France. Dec. 9, 1932, Nos. 35008 and 35009. Convention dates, Dec. 19, 1931, and Oct. 19, 1932. [Classes 108 (ii) and 108 (iii).] A suspension system for a four - wheeled vehicle comprises a fluid damper associated with each wheel, fluid transmission means between the diagonally opposed fluid dampers and compensating means interposed in said fluid transmission means. Fig. 1 shows fluid dampers 1 .. 4 associated one with each wheel and comprising attached compression cylinders 5 .. 12, communicating at their upper parts and forming a fluid reservoir. Pistons on each pair of cylinders are connected by a bell-crank lever to a rod coupled to the front or rear axle. The pistons may have automatic valves fluid-tight upon compression only to ensure filling of the system on the suction stroke. The cylinders are diagonally cross-connected by pipes 33 .. 36 in the run of which are interposed compensators A, B. Each compensator, Fig. 2, comprises a cylinder in which slides a piston 44 acted upon by opposed springs 42. The cylinder is closed by endplates in which are formed passages connected to the fluid transfer pipes as shown in Fig. 1. Communication between these and the cylinder is by means of oppositely acting oneway valves 59 .. 62 respectively and by ports 75, 76 registering with adjustable taper needles 37, 38. Valves 29, 30 which permit unobstructed flow in one direction only are screwed into the transfer passages, the arrangement being such that when one spring is compressed fluid is readily transferred to the complementary cylinder of the diagonally opposed pair, but on extension of one spring the resulting transfer of fluid is damped by the restricted passage through the valve. Should the resistance to movement of the piston in the opposed cylinder be too great for transfer to take place, the pressure fluid entering the compensating cylinder through valve 61 or 62 will force the piston to move from its mean position against the resistance of the opposing spring and that due to the throttling of the fluid expelled through the port 75 or 76 and past the needle valve. Valves 59, 60 are spring-loaded only to open when dangerous pressures are built up. A modified form of compensator is described in which the valves 59 .. 62 are omitted and the tapered needles are carried by the piston itself so that the degree of throttling of the fluid expelled by piston movement increases with the amplitude of movement. Remote control means such as shown in Fig. 4 may be provided to vary the setting of the needles in a compensator of the type shown in Fig. 2. A diaphragm 84 is clamped in a split housing 78, 80 of which part 78 is secured to the cylinder and plate. A needle 89 slides in part 78 and is spring held against the diaphragms. A plunger 91 sliding in part 80 rests on the diaphragm and may be moved axially to deflect the diaphragm by means of dashboard operated cam-shaft.

Title: Improvements in and relating to arrangements of grid-controlled converters by which a motor is fed from an alternating current network
IPC: H02M5/00
Filed: 1945-12-28
Abstract: 605,371. Converting; AKT.-GES. BROWN, BOVERI, & CIE. Dec. 28, 1945, No. 35041. Convention date, July 6. [Class 38 (ii)] In a system in which a motor is fed from an A.C. supply through grid-controlled converters, the reversal of torque accompanying reversal of rotation or regenerative braking is provided for by the grid of each converter being supplied from two control systems, only one of which is in operation at a time, the voltage of each control system being composed of two components having the supply frequency and the motor frequency respectively, the components of the same frequency for the two systems being phase displaced symmetrically compared with the zero point of the rectified voltage of that frequency. A known arrangement is described with reference to Fig. 1 (not shown) in which a three-phase synchronous type motor is fed from a three-phase supply through converters having 36 anodes, half of which are used for one direction of motor torque, and half for the other, and to reverse the torque the current is transferred from one group of anodes to the other by separate control systems for each group. According to the invention, only eighteen valves are used, one only being shown in Fig. 2, and two control systems are connected to the associated grid 13. The supply frequency component is fed through leads 14, 15 and the motor frequency component is added through Graetz-connected selenium cells 17 which also prevent control impulses from passing from one system to the other. One or other of the mutually phase-displaced stems is selected according to operating conditions. Mechanical contact control systems may be used in which case the blocking valves will be unnecessary.

In an impact, the driver's body first strikes the rim 10 as at F, causing flexure of the structure 12 to bring the rim towards the vertical until the driver's body contacts substantially the whole of the rim. Energy absorption then proceeds by deformation of the spokes 11 and of a further yieldable structure 18 which is superimposed on the cover 17 and has either steps (as shown), corrugations or holes formed therein to facilitate its collapse. The spokes may also be corrugated and need not be, as shown, formed integrally with the central structure.

Abstract: 1,027,705. Selective signalling. STANDARD TELEPHONES & CABLES Ltd. Aug. 28, 1964 [Sept. 4, 1963 (2); Sept. 14, 1963 (2)], No. 35347/64. Heading G4H. A magnetic core recoding circuit is characterized in that each core is associated with a single input combination of signals. In a first embodiment each input combination of signals sets all cores, except the one corresponding core, to their " one " condition. A further pulse, applied to all the cores, then causes that one core to be switched to its " one " condition and in so doing it induces a combination of signals in a set of output windings, thereby effecting the required recoding. In a second embodiment each input combination is arranged to switch only that one core to which it corresponds, thereby producing immediately output signals thus effecting the desired recoding. To compensate in the first embodiment for spurious pulses produced, by cores already in their " one " condition but which, because of the application of the further pulse make an excursion along a horizontal portion of the hysteresis curve, a second set of cores is paired with the first set and so arranged as to make a similar, but oppositely directed excursion, whereby similar, but oppositely poled, spurious signals are induced in the output windings, thus effecting the required compensation. To enhance the size of the output signals each output winding can form part of a transistor blocking oscillator.

Title: Improvements in cutting mechanisms for continuous-rod cigarette-making machines
IPC: A24C5/28
Filed: 1928-12-03
Abstract: 322,886. Rossler, K. F. W., and Ponndorf, K. F. A., (trading as R÷ssler & Ponndorf). Dec. 3, 1928. Cigarette-making machines. -In cutting-off mechanism for continuous-rod machines, the inclination of the helical knife 20 is adjusted to correspond with the alteration in speed imparted to the rod for varying the length of the cigarette. The knife is guided between cheeks 19 projecting from a plate 18, which rests against a companion plate on the cutter head 3. A set-screw 21 traversing a lug on each plate determines the relative position of the two plates and the inclination of the knife. Compensation for knife-wear is afforded through gearing within the cutter head. The knife is secured by a wedge 41 to a holder 42. A threaded spindle 39 passes through the holder and carries a bevel wheel 36 which is in gear with a second bevel wheel 35 on a spindle 34 having a spur-wheel 33. The hand-wheel 31 is pinned to a sleeve 25 which is eccentric to a supporting spindle 23 fixed in the head 3 and is integral with a gear 27, while a loose pawl 32 normally rests on the wheel 33. The knife is initially set when the machine is stationary by drawing out the wheel 31 and inserting a crank handle into the opening 48. The wheels 27, 33 are thus brought into .engagement. A fine adjustment during running is obtained by stopping the wheel 31, and the eccentric sleeve 25. As the wheel 33 rotates with the head 3 about the stationary eccentric 3 it is checked once per revolution by the pawl 32. A continuous automatic adjustment of the knife may be obtained by permanently fixing the sleeve 25 and placing a speed-reducing train between the spindle 34 and holder 42. The eccentrics which drive the rodguides 22 and the knife-grinders 57 are adjusted in correspondence with the rod-speed and knife inclination. A flange 62 on a collar 63 carried by the shaft 13 has a diametral guideway for the eccentric ring 61, the position of which is fixed by a screw 68 fitting in a bracket secured to the collar. The square heads of the screws 66, 67, 68 are accessible through an opening 69, normally closed by a disc 71 and cover 70. Latches 84 pivoted at 85 have pins engaging radial slots 82 in a disc 81 on the square end 80 of the central spindle 77. This may be turned by a handle 79 to operate the latches, and a nut 76 integral with a handle 75 tightens the cover by acting on the flange 73 of the sleeve 72. Lubrication is effected by way of a funnel 91 and pipes 92.
