Title: Apparatus and method for controlling the stitch lengths of knitted fabrics
IPC: D04B9/02
Filed: 1965-01-19
Abstract: The instrument cams of the parent Specification are adjusted by pneumatically operated mechanism in response to any variation from a predetermined relationship between the rate at which the yarn is positively fed to the needles of a circular machine and the rate at which it is absorbed by the instruments in producing the knitted fabric.  The yarn is positively fed to the needles of the machine by positive yarn feeding mechanism 202, Fig. 1 (not shown), as described in the parent Specification, and is engaged by the eye 209 of a yarn tensioning arm 210 in its passage to the yarn feeding guide 211 of the machine feeding it to the needles of the machine machine.  The arm 210 is secured in a block 210, Figs. 4 and 7 (not shown), which is pivotally passed in one direction by a spring 222 so that a predetermined tension is imposed on the yarn by the arm 210.  Air is fed under pressure from a pipe 238 into an opening 243 in the bottom of a housing 213 containing a piston 245.  A flexible seal 244 prevents the air from escaping between the housing and piston seals and an opening 251 is provided in the piston to permit the air to feed through it into a chamber having an outlet nozzle 256 pivoted in a slot 258 in the piston is a flap valve control arm 257 which is spring loaded to close the nozzle opening 256 and prevents the escaping air therefrom.  In such circumstances the air pressure in the opening 243 causes the piston to rise until a rod 234 connected to the block 220 engages the end of the arm 257 whereupon the latter is pivoted to open the valve and permit the air to escape from the nozzle 256.  When a state of equilibrium is reached between the air entering the opening and the air leaving nozzle 246 the piston remains stationary.  Connected to the piston is an arm 268 pivoted at 270 and engaging with its end opposite from the piston a stitch cam slipport 274.  Consequently any rise or fall of the piston causes the needle cam to be lowered or raised accordingly so that the needles take more or less yarn.  As the yarn is positively fed any variation between the rate of feed and the rate of consumption is observed by the yarn twisting arm 210 with corresponding movement resulting in the rod 234 opening or closing the valve control arm 257 which results in pneumatic adjustment of the piston and corresponding adjustment of the stitch cam whereby the two rates are returned to a state of equality.  Alternatively the sinkers can be controlled by their cam being controlled by their cam being controlled by the mechanism on the loop wheel of a binded needle machine cam 4 moved further away or nearer to the needles.  The block 220 engages contacts 229 in the event of the arm moving beyond certain limits to cause stoppage of the machine.

Title: Improvements in or relating to commutators for electric motors and the like
IPC: H01R43/08
Filed: 1943-02-11
Abstract: 563,228. Commutators for dynamoelectric machines. LIMIT ENGINEERING CO., Ltd., and COLLINS, A. L. Feb. 11, 1943, No. 2315. [Class 35] In the method of producing a commutator by forming upon a metal contact member a row of undercut lugs, moulding a block of insulating material around and between the lugs and then splitting the contact member between the lugs into a series of segments, the undercut shape is imparted to the lugs by squeezing them between dies prior to the moulding operation. In one method, a copper strip 10, Fig. 1, formed initially with transverse projections 11, is bent into a ring, Fig. 3 and squeezed between dies 13, 13a, Fig. 5, having end faces 14, 14a which impart a trapezoidal shape to the projections. The space between the ring and an inner metal bush 16, Fig. 6, is then filled with moulded synthetic resin 15 and the commutator finished by cutting slots 18, Fig. 7, in the ring between the projections 11, the joint 17, Fig. 6, between the ends of the strip serving to position the first cut. In modified processes the projections may be formed after the strip has been bent into a ring, or the undercut shape may be imparted to the projections whilst the strip is straight. A thick walled metal tube having internal projections may be employed instead of a bent strip.

Filed: 1975-01-21
Abstract: 1490411 Variable-speed gear CLARK EQUIPMENT CO 21 Jan 1975 [21 Jan 1974] 2665/75 Heading F2D Epicyclic gearing in a split-torque, hydromechanical, dual-range transmission has a planet carrier 50 which drives an output shaft 64, internal ring gears 52, 60 either of which may be driven by the input shaft 12 through gears 14, 18, an intermediate shaft 20, gears 22, 24 and friction or toothed clutches 26, 28, and a sun wheel 44 with a driving connection 40 with a hydraulic pump/motor unit 38, preferably of fixed displacement, having connections 35, 37 with a pump/motor unit 34, preferably of variable displacement, driven through gearing 30, 18 from the intermediate shaft. The carrier 50 has a plurality of planetary pinions 46 meshing with the sun wheel and with the ring gear 52, and a plurality of further pinions 56 meshing with the pinions 46 and with the ring gear 60. Low range is established when the clutch 28 is engaged to drive the ring gear 52, the output shaft being accelerated from rest as the displacement of the unit 34 is varied from a setting in which the sun wheel is rotated in the opposite sense to the ring gear 52. Maximum output speed in low range is achieved when the displacement has been adjusted through zero to maximum in the opposite sense. At this speed the gear 22, due to its connection with the epicyclic gearing, will be rotating synchronously with the shaft 20 so that the clutch 26 may be engaged and the clutch 28 released to establish high range. Further increase in output speed is then obtained by adjusting the displacement of 34 back over its range. Forward and reverse clutches may be added to the input or output. The Specification demonstrates the use of formulµ for determining optimum sizes of the planetary gearing elements, &c. for given operating conditions.

Patent GB-339146-A (GB)
Title: Improvements relating to remote reading compasses and like instruments
IPC: G01C17/26
Filed: 1929-11-25
Abstract: 339,146. Thomas, C. W. I., and Radiovisor Parent, Ltd. Nov. 25, 1929. Tell-tale apparatus. - In apparatus for repeating indications at a remote point more particularly for repeating compass readings, the master instrument controls a non-translucent disc 2, Fig. 1, having sets of radial slots W, V, which co-operate respectively with pairs of light-sensitive cells, or apertures S, T, communicating therewith, to control a step-by-step repeating instrument. Upon rotation of the disc 2, the cells of each pair are lit in sequence the priority of exposure determined according to the direction of rotation being adapted to control the direction of rotation of the secondary indicator. Fig. 2 shows the equipment, comprising a pair of light-sensitive calls 20, 21, associated with a single set of radial slots. The width of each slot corresponds to the width of a pair of apertures or cells. When the direction of rotation is such that the cells are exposed in the sequence 20, 20 and 21, 21 and so on, cell 20 operates relay 22 which prepares the circuit of stepping magnet 28 of the repeater 34 over contacts 26 and opens the circuit of the relay 29 associated with cell 21. The following exposure of both cells 20, 21 causes (1) operation of stepping magnet 28 over the circuit of cell 21 and (2) continued operation of relay 22 to maintain the circuit of the magnet 28. The common armature 24 of the relays 22, 29 has flexible contact arms 34, 35. When after exposure of both cells, cell 21 is exposed alone relay 29 is energized to prepare the circuit of the stepping magnet 32 so that in the event that the master instrument reverses its direction both, cells are again illuminated and the magnet 32 operates the repeater in the reverse direction. Continued movement in the same direction however repeats the above described sequencer of illumination of cells 20, 21 to operate the stepping magnet 28 while movement in the opposite direction reverses the sequence and thereby effects operation of magnet 32. In order to increase the sensitiveness of the repeater additional series of slots e.g. V may be employed in staggered relationship to control equipment similar to that shown in Fig. 2, the ratchet wheels being adapted to actuate a common repeater. The disc 2, Fig. 1, may be formed of opaque material with slots as of transparent material washed photographically or by printing.

Title: Improvements in the process of bleaching textile fibres, yarns and fabrics
IPC: D06L4/15
Filed: 1935-01-29
Abstract: Textile fibres, yarns, and fabrics are bleached by means of a non-alkaline bleaching bath containing hydrogen peroxide stabilized by an organic acid, phosphoric acid, or boric acid, with the goods travelling continuously through the bath, or the liquor maintained in continuous flow into and out of the bleaching vessel, or with the goods and the liquor flowing in countercurrent through the vessel. Suitable organic stabilizing acids are oxalic acid and lactic acid. The presence of sulphuric, hydrochloric and nitric acids is excluded. The goods may contain activators such as soap or alkali, and the bath may contain protective agents such as glue, gelatine, or formaldehyde.  In an example, wool containing small amounts of soap and fat is passed through a bath containing 0,5 per cent of hydrogen peroxide and 0,01 per cent of oxalic acid which is circulated and constantly kept up to strength.  The wool is then passed through hot rollers. In another example wool goods are packed into a container through which is circulated a solution of hydrogen peroxide stabilized with mono-sodium phosphate.  The solution is kept up to strength by adding hydrogen peroxide and phosphoric acid.  The goods are then treated with ammonia, drained, and dried.  Specifications 277,628, [Class 1 (ii)], 347,292, and 404,019 are referred to.  The Specification as open to inspection under Sect. 91 refers to the treatment of sensitive organic materials, particularly fibres, in aqueous stable solutions of oxygen-yielding bleaching agents like hydrogen peroxide or compounds having the -OOH- group, while moving the material and/or the liquor.  Stabilizing agents specified are colloids, alkali salts of organic sulphonic acids, or esters of sulphuric acid.  The materials may contain activators such as enzymes, ferments, metal salts and oxides (other than those of the iron group), or compounds capable of increasing the pH value.  The process may be combined with washing, oiling, greasing, impregnating, preserving, or dyeing the material in the same or different baths, and agents specified for these purposes include sodium dodecanolsulphate, triethanolamine, sodium octadecoylmethylaminoethane sulphonate, sodium dodecanolpersulphate, sodium 3, 5, 3<1>, 5<1>, tetrachloro-2, 2<1>-dioxytriphenylmethane-2<11>-sulphonate (deterrent for insects), acid fluorides, hydrofluoric acid, fluoboroacetic acid, fluoboro-oxalic acid, fluosulphonic acid.  Preservatives specified are sugar, tannins, aluminium salts, gelatine, glues, resinates, salts of aromatic polynuclear sulphonic acids, and solium formaldehydesulphoxylate.  Other examples are given.  This subject-matter does not appear in the Specification as accepted.
