Title: Improvements in knitting machines
IPC: D04B15/99
Filed: 1944-05-15
Abstract: 589,646. Knitting-machines. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. May 15, 1944, No. 9248. Convention date, May 27, 1943. [Class 74 (ii)] In changing the speed of a commutator motor driven knitting-machine, the lugs on the lug chain merely prepare the machine for a change of speed by closing a contact 9 so that the attracted armature 11' of an electromagnet 11 presses an arm 13 out of engagement with an arm 14, the initiation and duration of the changed speed being thereafter determined by the arm 14 which, under the control of the cam 17 on the camshaft of the machine, rotates about a pivot 15 to open a contact 21 in a relay circuit 23 and close a contact 20, in a relay circuit 22, or vice versa. The relay associated with contact 20 causes a brush displacement motor 2 to move the brush bridge of the driving motor 1 to a position providing a lower narrowing speed previously determined by the setting of a wheel 6; and the relay associated with contact 21 causes the motor 2 to restore the brush bridge to the normal speed position. The normal knitting speed is regulated by a rod 4 which, through a lever 5 and a shaft 5<1> acts on contact arms in an apparatus 3, of the kind described in Specification 471,711. The drums are driven from the motor 2. A low speed for knitting toe and heel is set by means of a wheel 7. The cam 17 may be made in two parts movable relatively to each other to vary the duration of the lower speed and rotatable about the cam shaft to vary the moment of commencement thereof.

Patent GB-513066-A (GB)
Title: Electrical relay device responsive to small changes of a magnitude such as current or voltage
IPC: H01H53/10
Filed: 1938-03-28
Abstract: 513,066. Electromagnetic relays. ENGLISH ELECTRIC CO., Ltd., and TILSTONE G. March 28, 1938, No. 9418. [Class 38 (v)] A relay responsive to small changes of current or voltage has a rotor 3 with a horizontal spindle 5 supported from below on anti-friction bearings and held down on them by gravity and magnetic attraction. The bearings consist of discs 4 arranged on axes 4a, 4b, and the magnetic force is produced by the rotor 3 being arranged nearer to the lower pole 7 of the stator magnet than to its upper pole 6. One or both poles are shaded so as to tend to rotate the rotor 3 which consists of a metal cylinder formed wholly or in part of steel, and with normal voltage this turning force is exactly balanced by spring, gravity or electric biassing means, e.g., by a weight 14 slidable on an arm 11 fixed to the rotor. Variations of voltage cause the rotor to rotate and a tilting mercury switch to be operated, or, as shown, a contact 15 or 16 to be engaged. The rotor carries an arm 8 of magnetic material adapted to be attracted by a permanent magnet 9 into the neutral position shown. Since rotation of the rotor in either direction will cause this attraction to diminish a decisive movement of the rotor is obtained. The magnet 9 is radially adjustable to vary the sensitivity. The bar 8 may also carry an aluminium vane to form an eddy-current damping device.

Filed: 1935-03-27
Abstract: 1 : 3 : 5-Xylenol or an alkali metal salt thereof is esterified with a phosphating agent, e.g. phosphorus pentachloride or oxyhalide. Coal tar acids boiling between 218 and 222 DEG  C. may be used as the source of the xylenol; on heating under reflux with phosphorus oxychloride they yield a mixture containing the desired ester.  This mixture is washed with alkali, or distilled to remove free phenols and may be treated with activated charcoal, fuller's earth, soluble permanganates or other decolorizing agents.  The xylenol may also be converted into its alkali salt and treated with phosphorus pentachloride, possibly in the presence of benzene or toluene.  Tests are described designed to determine (a) the toxicity of the esters when fed to chickens; (b) the presence of oxidizable components--by means of permanganate and/or bromide/bromate solutions.  The xylenol phosphates may be incorporated in cellulose ester, cellulose ether, resin and rubber compositions, e.g. as plasticizing, waterproofing and fireproofing agents.  The compositions whether used for moulding, for making filaments, films or foils or for coating fabrics may contain pigments, fillers, dyes, lakes, castor oil, linseed oil, dimethyl or diethylphthalate, or ethyltoluenesulphonamide.  The xylenol phosphates may be mixed with pyroxylin, resins and gums to form lacquers, and may be added to compositions for waterproofing and sizing films, fabrics and papers and to polishes, soaps and inks. Compositions containing the phosphates and gum damar, paraffin wax, alcohol, ethyl and butylacetate, toluene and benzene may be applied to films, foils and sheets, and the phosphates may be used as vehicles for grinding pigments, and as transformer oils.  Cellulose ester and ether and regenerated cellulose foils or coatings thereon containing the phosphates may be used for wrapping foods, and the phosphates are useful in the recovery of phenols, amines from coal and peat distillation gas liquors.  The use of the phosphates in cellulose formate, acetate, propionate, butyrate and nitrate and methyl, ethyl and benzyl cellulose compositions is specifically mentioned.ALSO:Tri-1 : 3 : 5-xylenolphosphate is used as a plasticizer in lacquers and other coating compositions and as a detergent in soaps.  It may also be used in waxes and polishes and mixed with resins and gums to form lacquers or lacquer bases. Coating compositions for films, foils and sheets may contain besides the phosphate, gum dammar, paraffin wax, alcohol, ethyl or butylacetate, toluene and benzene.  Coating compositions for water-proofing and sizing synthetic films, fabrics and paper may contain the phosphate as plasticizer.ALSO:Tri-1 : 3 : 5-xylenolphosphate is used as a modifier for rubber, and may be added to sizes or synthetic films, fabrics and paper.
