Title: Improvements in and relating to controllers for electric motors
IPC: H02P3/06
Filed: 1938-07-26
Abstract: 513,814. Master control of D.C. motors. IGRANIC ELECTRIC CO., Ltd. July 26, 1938, No. 22182. Convention date, July 30, 1937. [Class 38 (iii)] Non-regenerative braking.-Rheostatic braking circuits for series motors A, A', comprise closed loops each including the armature of one motor and the field of another, means being provided to vary the resistances of the loops, and certain of the reductions of resistance being subjected to a predetermined time delay. With a controller 33 in its off position the rheostatic braking circuits are completed with a resistance R' in one circuit and a resistance R" in the other. Movement of the controller to either of its positions 1 de-energizes contactors 27, 28, so that resistances R<3> and R<13> are added to the respective braking circuits. Upon further movement of the controller contactors 25, 26, are energised to add further resistances R<2>, R<12>, to the braking circuits. Further movement of the controller energizes contactors 20, 21, 22 and 23, to interrupt the braking circuits. The position to which the controller is returned to effect braking is selected in accordance with the speed at which the motors are operated. When the controller is moved back towards its off position, the switches 20, 21, 22, 23 complete the braking circuits with all resistance inserted, and although movement of the controller position 1 opens the energizing circuits for contactors 25, 26, these circuits are maintained by a switch 31. A coil 31a. operating 'the switch 31 is energized when the controller occupies its position 1, but a winding 31b short-circuited by de-energization of the switches 20, 21, 22 and 23, prevents opening of the switch 31 for a predetermined time. When the switch 31 opens, contactors 25 and 26, short circuit resistances R<2>, R<12>. In the off position of the controller contactors 27, 28 are energized to short-circuit resistances R', R", subject to control by relays 29, 30, which must reclose in response to the decrease of braking current before the contactors 27,. 28, are energized. These contactors 27, 28, are controlled by the relays 29, 30 to reinsert the resistances R', R", if the braking current subsequently exceeds a predetermined value. Upon failure of power the braking circuits are established with an intermediate value of braking resistance. In a modification, Fig. 4, not shown, the braking control is effected by a separate controller, which in operation from an off position sets up the braking circuits and excludes the resistances R<2>, R<12>, and R<3>, R<13> in steps.

Patent GB-223888-A (GB)
IPC: D06P1/92
Filed: 1924-09-22
Abstract: In a process for printing textiles by the usual methods and fixing by steam, ethylene glycol and ethylene chlorhydrin are employed singly or together as constituents of the printing pastes, fuller and brighter shades being thereby obtained. Special advantages accrue when the additions are made to strongly alkaline pastes and to colour discharges with basic dyestuffs on wool and cotton.  Examples show the use of ethylene glycol for weighted silk in pastes containing Eriochrome red B, ammonia and gum, and for chlorinated wool in pastes containing Solid blue B, gum and ammonium oxalate.  The use of ethylene chlorhydrin is exemplified for weighted silk in pastes containing Chromazurol S conc., chromacetate and starch tragacanth; for unweighted silk in pastes containing Acid orange A, gum and ammonium oxalate; for chlorinated wool, weighted silk and cotton in paste containing Solid blue RR spirit-soluble and starch-tragacanth, and in the case of cotton and optionally for weighted silk tannin, the cotton being after-treated with tartar emetic; and for cotton and artificial silk in pastes containing methylene blue, acetic acid, starchtragacanth, tartaric acid and tannin, the fabric being after-treated with tartar emetic.  The Specification as open to inspection under Sect. 91 (3) (a) also gives examples of the use of ethylene glycol for chlorinated wool, weighted and unweighted silk, and cotton in pastes containing Nigrosine fat-soluble and starch-tragacanth, and in the case of cotton, and optionally for weighted silk, tannin, the cotton being after-treated with tartar emetic.  This subject-matter does not appear in the Specification as accepted.

Abstract: 436,684. Stop valves. COCKBURNS, Ltd., and MAcNICOLL, D., Clydesdale Engineering Works, Cardonald, Renfrewshire. Aug. 1, 1934, No. 22409. [Class 135] A stop valve comprises a valve element 1 between an upstream valve seat 2 and a downstream valve seat 3 which is permanently constrained towards the seating 2 by a spring 5 acting through a lever 6, spindle 7 and fork 8, the valve being opened by the fluid pressure on the upstream side acting against this spring. An emergency trip device is provided comprising a strong stressed spring 14 acting on a lever 15, which is normally retained by a catch 16, to pull the valve 1 over on to its downstream seat 3, against the resistance of the spring 5 when the catch is released. A slot and pin engagement 17, 18 is provided between the levers 15 and 6 to allow free operation of the valve without disturbing the emergency trip. The valve 1 can be positively seated on the seat 2 and the emergency trip reset by a spindle 10 which for normal operation is withdrawn. The valve also acts as a safety cut-off since if the pressure on the downstream side falls appreciably the valve 1 is closed on to its seating 3 by the fluid pressure alone.

Abstract: 921,692. Vibratory mechanism. CONTINENTAL OIL CO. June 22, 1961, No. 22664/61. Class 80 (4). In a vibratory mechanism, particularly for seismic exploration, linear vibrations of variable frequency but constant force are produced by two oppositely-rotating weights 14 on parallel shafts 8 driven by a variable-speed prime mover 6, the effective mass of each weight 14 being reduced as the speed increases by a respective radially-slidable counterweight 16 loaded by springs 26. Each weight 16 is carried by a pair of rods 18 slidable in bores in the respective weight 14. Each spring 26 is designed to oppose the centrifugal force on the counterweight 16 at a varying rate so that the counterweights are correctly positioned at all speeds to give a constant vibratory force. The varying spring rate may be obtained by a varying wire size or mean diameter or by using a plurality of nested springs or by a combination of types of springs or hydraulic springs.

Abstract: 500,979. Oily condensation products. LOWES, A. P., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 20, 1937, No. 22919. [Class 2 (iii)] Oily products suitable for lubricating purposes are prepared by condensing a chlorinated long chain aliphatic hydrocarbon containing between 3À3 and 4À6 atoms of chlorine per molecule, or a mixture of such hydrocarbons, with benzene or a homologue of benzene in the presence of aluminium or anhydrous aluminium chloride and subjecting the product to a mild cracking operation. The cracking may be carried out simultaneously with the isolation of the product by treating the reaction mixture resulting from the condensation with an amount of water less than that required to convert the whole of the aluminium chloride to hydroxide and heating the mixture to above 200‹ C., preferably above 250‹ C. The amount of catalyst employed is preferably from 6 to 30 parts of aluminium chloride or from 1 to 6 parts of aluminium for every 100 parts of chlorinated hydrocarbon. The oily products may be separated from the condensation mixture by the method described in Specification 473,334. The cracking may be effected by heating the oil for “ to 1 hour at 200 to 300‹ C. in the presence of 0À2 to 1 per cent of its weight of a cracking catalyst such as iron, aluminium, nickel or salts of these metals, especially the halides.

Title: Improvements in or relating to draw off mechanism for straight bar knitting machines
Inventor: START ERNEST
IPC: D04B15/88
Filed: 1958-07-17
Abstract: 928,951. Knitting-machines. WILLIAM COTTON Ltd. Sept. 8, 1959 [July 17, 1958; Sept. 11, 1958], Nos. 22922/58 and 29100/58. Class 74 (2). A blank being knitted on a straight-bar machine is initially drawn off by a carriage 4 bearing a removable bar 5 with points 6 on to which a welt 7 has previously been run; but when the carriage has reached the pusher 8, subsequent draw-off is effected by main means of reversible travelling-band type, constituted by flexible strips 13 hooked by their extremities 15 to endless chains 16 and having secured to them the ends of a bar 35 bearing points 36 which, moving from a starting position, Fig. 1, project in a fabric-penetrating attitude, Fig. 5, as the strips carry the bar around pulleys 21 (since the bar does not readily follow the curve) and then swing to an attitude parallel to the strips, to be so maintained by tabs 37, the fabric being thereafter drawn off substantially flat by the points 36 and being pressed off when those points reach a position below bristles 33. Each division of a multi-division machine may be so equipped. A shaft 29 bearing driving sprockets 17 for the chains is then turned by hand to return the points to their starting position, ready to draw off fabric knitted to the next welt which has meanwhile been transferred to the machine, the bristles 33 stripping the pressed-off blank from the points 36. The bar 35 may be removably mounted on spigots 37a on the strips 13, so that it may be substituted by a bar having draw-off hooks for use with a welt stick drawing off fabric having a turned welt. The shaft 29 may be turned by hand to the point where the points 36 have pierced the fabric. Power operation of the shaft 29 in draw-off direction may be by continuously operated pawl 39 and stop-pawl 43, which may be disabled by bluffs 45, 46, operated by a hand grip 48 and held in disabling position by an arm 49 controlled by a hand grip 51, or by a cam disc 52 on a shaft 12 bearing a roller 11 for straps 10 operating the carriage 4. Alternatively, shaft 29 may be turned in both directions, under control of a pattern chain 69 passing over a sprocket 68 on the shaft 29, by a reversible electric motor 159 through an electrically-operated clutch. Arms 59 may replace the points 6 for the initial draw-off. Specifications 548,874 and 797,871 are referred to.
