Filed: 1948-08-04
Abstract: 654,892. Counting-apparatus. METROPOLITAN VICKERS ELECTRICAL CO., Ltd. Aug. 4, 1948, No. 20597. [Class 106 (i)] Small undulations or corrugations, such as the edges of a stepped stack of sheet material 1, are counted by drawing an electromechanical pick-up device 2 over them, scaling down the impulses from the. pick-up 2 by means of an electronic counting-down circuit and applying the scaled-down impulses to an electromagnetic counter, e.g. of the telephone call meter type. An amplitude-limiter is preferably included in the pick-up output to discriminate against impulses due to surface roughness of the material. In Fig. 2 the output is applied by an adjustable potentiometer P1 and through a scratch filter R2-C1 to an amplifier V1. The amplified output is passed through a diode limiter V2, which passes pulses of amplitude above the level pre-set by a potentiometer P2, to a further amplifier V3. After D.C. restoration by V4, the pulses are passed through a pulse shaper to the counting-down circuit which operates the electromagnetic counter. Interpolation of the counter readings may be given by neon indicators controlled by the counting- down circuit.

[Also in Group XXXIX] To prevent back-spacing extending beyond the current recorded message, a distinctive change of signal is produced on the record at the end of each message, and back-spacing is arranged to be stopped whenever this change of signal is encountered. As shown, a dictator at a substation 10 may record a message on track 22a of tape 22 by means of recording amplifier 36 and message head 28. The end of a message is indicated on a second track 22b by a 100 c/s. pulse, produced by generator 48 in response to operation of push-button 16 by the dictator or to replacement of a hand-set and recorded by means of tabulating head 30. During play-back or back-spacing, the machine is stopped when head 30 encounters one of these pulse signals, which also operate a counter 86. When back-spacing is stopped in this way, play-back is automatically initiated. The tape drive is as described in Specification 832,171, and a two-reel tape magazine as described in Specification 853,873 is used. Specification 865,014 also is referred to.

Abstract: 904,866. Hydraulic pit props. DOWTY MINING EQUIPMENT Ltd. June 29, 1959 [June 30, 1958; July 11, 1958; Oct. 8, 1958], Nos. 20820/58, 22356/58 and 32144/58. Class 20 (2). [Also in Group XXVIII] An hydraulic telescopic pit prop comprises a piston 25 adapted to be forced out of a cylinder 13 to extend the prop, and an outermost cylinder 10 in which the cylinder 13 slides and to which the piston 25 is secured. The cylinder 13 comprises two concentric cylinders 17, 18 joined at their upper and lower ends respectively by a roof-engaging cap 19 and a gland ring 21. The outermost cylinder 10 has welded to its upper end a bearing-ring 12 having two bearing surfaces 14, 15 engaging the cylinder 13. There is clearance between the piston 25 and the cylinder 18 except at the gland 21 and the base 27 of the cylinder 25 has lateral play and curved engaging surfaces within a recess 31 of the base 11 of the outermost cylinder 10. The pit prop reservoir is the space 35 between the cylinders 17, 18. The pump for extending the prop comprises a plunger 37, Fig. 3, in a bore 36 in the cap 19 which is adapted to draw liquid from the reservoir 35 by a port 44 and force it into the pit prop pressure space 34 by a valve 53 and a passage 54. To release the prop the plunger 37 is moved beyond its normal range, causing a pin 55 in the plunger to open the valve 53 to discharge liquid from the space 34 by the passage 54, a transverse bore 56 in the plunger 37 and a bore 57 which is in register with the bore 56 in this position of the plunger, and a passage 59 to the reservoir 35. The reservoir 35 breathes through a passage 65 and bores 63, 64 in the plunger 37 when it is moved away from a packing-ring 39. The plunger 37 is operated by a lever 46 having a head 47 held in a clevis 49 pivoted at 51 on the cap 19, the lever engaging the plunger by a roller 48. A modified pump, Figs. 4 and 5, comprises a piston 80 in the upper portion of the cylinder 18 reciprocated by a manually-operated crank-shaft 72. On the downstroke of the piston, liquid is drawn from the reservoir by a tube 78, a passage 79 and an inlet valve 81 to the space 83 above the piston 80 and on the upstroke, liquid is forced into the prop pressure space 34 through a valve-plate 76. The valve-plate 76 is opened by a pin 77 when the piston 80 is left in its highest position when the prop is set, so that excess pressure in the pit prop can be relieved through a relief valve 85, which discharges back to the reservoir, and the prop can be released by raising a valve 87 in the valve 81 by a spring-returned pin 92 and a lever 88, the valve 81 eventually also opening.

Abstract: 1387289 Piecing; end catcher; threading travellers MAREMONT CORP 4 May 1972 [3 June 1971] 20905/72 Heading DID A piecing carriage mounted on a ring spinning machine comprises a servicing assemlbly 56 which can move vertically and generally horizontally towards the spinning machine to be supported by the ring rail for movement therewith. The servicing assembly 56 is mounted for movement from a position above the maximum elevation of the ring rail, and is connected to a servicing assembly support 112 which moves laterally to a position overlying the ring rail in response to the vertical movement of the assembly from its maximum elevation. As shown, the moving piecing carriage carrying piecing devices stops in front of the spindle requiring servicing. A latch (110) is then released and the end-catching/threading servicing assembly 56 descends under gravity and a support 112 (Fig. 8) swings out by spring or gravity over the ring rail to support the assembly thereon and move vertically therewith. The end catching/threading servicing assembly 56 is then pivoted forwardly to the position illustrated in Fig. 8 and aligned on the ring. This forward movement brings a suction nozzle 60 and yarn unwinding device adjacent the bobbin (Fig. 12, not shown). The free end of the yarn is then unwound and drawn into the suction tube 60. An air blast from a nozzle (70) moves the traveller around the ring to a position adjacent tab (192, Fig. 12). The end catching/threading unit is then retracted (Fig. 10, not shown) to bring a thread guide (94) into operation, and then advanced again to thread the yarn by using a second blast of air from nozzle (70) to move the traveller around the ring. After threading of the yarn onto the traveller, the servicing assembly is retracted and raised to its initial position (Fig. 1).

Title: Improvements in or relating to organic polymeric products
Inventor: BECHTOLD MAX FREDRICK
IPC: D01F6/18
Filed: 1954-07-20
Abstract: Aqueous dispersions are prepared from a water-soluble organic polymer dissolved in an aqueous solution of a metal salt, the salt being one which in concentrated solution dissolves the polymer and which is present in a proportion of at least 50 per cent by weight of the polymer but in an amount insufficient to form a solution which dissolves the polymer.  Polymers specified are polyacrylonitrile, copolymers of acrylonitrile with vinylidene chloride, butyl methacrylate, butadiene, styrene and isobutylene, polymethacrylonitrile, copolymers of methacrylonitrile, polyvinyl alcohol, in admixture with polyacrylonitrile, a propylene/sulphur dioxide/maleic anhydride copolymer, polytetrafluoroethylene in admixture with polyacrylonitrile, and polytetramethyleneurea. Salts specified are the water-soluble thiocyanates, iodides, bromides, and chlorides of Group I and II metals, such as lithium bromide and iodide, sodium thiocyanate and iodide, potassium, magnesium and manganese thiocyanates, calcium thiocyanate, bromide, iodide and nitrate, zinc thiocyanate, chloride, bromide and iodide, and cadmium iodide.  The dispersions may also contain other substances such as "nonsolvent" salts, clay, silica, acetone and alcohol.  The polymer dispersions may be formed into shaped articles, such as films and filaments, by first casting or spinning the dispersion, then removing the water, preferably by the application of heat, and finally removing the salt by washing with water; the resulting polymer structures may be oriented by stretching.  Objects thus prepared from polymers of acrylonitrile and methacrylonitrile may be softened or plasticised by treatment in liquids such as trimethylene glycol di-2-ethylhexanoate, polyethylene glycol, polyalkylene glycols and esters known under the Registered Trade Mark "Ucon," cyclic trimethylene carbonate, tetramethylene cyclic sulphone, the dilactone of 4,7-dihydroxy decanedioic acid, N-lauryl-N-methyl formamide, phenyl diglycol carbonate, phenyl cetane sulphonate, adiponitrile, o-nitrobiphenyl, caprolactam, and a solution of methyl phthalyl ethyl glycolate or dibutyl phthalate in isopropyl alcohol.  Opaque films produced from the dispersions may be cleared by the application of pressure, and this property may be used in engraving, tracing and other similar applications.  The property of forming opaque but clearable films is exhibited particularly by acrylonitrile/isobutylene copolymers and polymethacrylonitrile, which latter may be used alone or in admixture with another polymer, e.g. a butadiene/acrylonitrile copolymer.  The preparation is described of polyacrylonitrile, polymethacrylonitrile and copolymers of acrylonitrile with butyl methacrylate, styrene and vinylidene chloride, by polymerizing the monomers in aqueous emulsion containing sodium lauryl sulphate as emulsifier, and potassium persulphate as catalyst which may be used in conjunction with sodium bisulphite.
