Title: Improvements in and relating to electric motors
IPC: H02K7/104
Filed: 1931-02-06
Abstract: 372,794. Brakes. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and YOUNG, A. P. ; Borrowell, Borrowell Lane, Kenilworth, Warwickshire. Feb. 6, 1931, No. 3833. [Class 103 (i).] An induction motor having two stator elements mounted at oppo- .site ends of a diameter of the rotor, and a rotor 1 with a cylindrical flange of conducting material, has one or more braking permanent magnets 7, 8 between the poles of which the rotor flange passes, and these magnets are pivoted for limited rotation about the rotor axis 2, the movement being limited by a spring 14. The stator elements each consist of cores carrying potential and current coils 12<1>, 6 respectively. To increase the braking effect, a pad 15 may be connected to the bar 9 carrying the permanent magnets 7, 8 and to the frame 5 by links 10, 11 so that it acts as a mechanical brake when the magnets move, or the movement of the permanent magnets may vary the magnetic damping by means of a fixed magnetic shunt. Specifications 17247/15 and 193,752, [both in Class 40 (ii), Phonographs &c.], are referred to.
Patent GB-578528-A (GB)
Title: Improvements in the discharge-printing of textiles
IPC: D06P5/15
Filed: 1944-03-01
Abstract: Coloured fabrics are discharge-printed without degradation of fibres by applying to the textile a paste containing aqueous sodium chlorite as the active ingredient and thereafter subjecting the fabric to an auxiliary treatment to ensure the maximum effect. The process is applicable generally to textiles dyed with sulphur, direct or developed type, e.g. azo and naphthol colours to effect either the substantially complete, or the partial discharge of the colour medium, but with vat dyes, figures of reduced shade intensity are usually produced.  The fabric is printed in known manner with a paste comprising sodium chlorite, water and a thickening material, e.g. starch, gum arabic or gum tragacanth, advantageously at approximate pH 5-6, effected by inclusion therein of substances such as stearic, oleic or acetic acid or a suitable buffer and followed by exposure to an approximate temperature range of 160-250 DEG  F. as by passage over heated drums or by steaming at atmospheric or somewhat higher pressure. Optimum proportions of sodium chlorite depend upon the nature of the dyestuff, the extent of discharge desired and the temperature of the auxiliary treatment.  In examples: (1) a fabric dyed a heavy shade with Calcomine Brown 2GT is printed with a standard paste, e.g. a mixture of water and starch or gum adjusted to pH 5 to 6 with acetic acid and containing 6 per cent sodium chlorite, based on the weight of the paste and added in aqueous solution prior to passing the fabric directly on to "drying cans" at approximately 240 DEG  F. and subsequently washing to effect almost complete discharge of the colour medium from the treated portion. Similarly, treatment applied to fabrics dyed a heavy shade (a) with Katigen Brown R; (b) with Diazo Brown RD; (c) with Ponsol Brown BB results in an approximately 50 per cent discharge of colour in (a) and (b) and approximately 15 per cent in (c); (2) a fabric dyed with Katigen Brown R is printed with a mixture of water and tragacanth containing 4 ozs. sodium chlorite per gallon of the gum and the fabric is passed directly on to "drying cans" at approximately 240 DEG  F., prior to washing and drying to furnish a substantially complete discharge of the dyestuff.  Comparable results are obtained with a fabric dyed with a developed azo-type dyestuff, e.g. produced on the fibre from Diazo Brown RD and Naphthol AS Supra Fine.  The fabric itself in (1) and (2) is heated to within 160-212 DEG  F. in passing over the "drying cans".

Title: Improvements in cutting machines for cutting fabric or the like into bands
IPC: D06H7/04
Filed: 1964-01-29
Abstract: 1,049,946. Slitting apparatus. S. G. ANDERSSON. Jan. 29, 1964 [Jan. 29, 1963], No. 3881/64. Heading B4B. A machine for longitudinally cutting fabric or the like into bands comprises knives 1, Fig. 5, adjustable transversely of the cutting direction, which are mounted with equal spacing on the links of a lazy-tongs mechanism 18, Fig. 4 (not shown), by means of which the spacings between the knives are adjusted while maintaining the equality of spacing. As described, each knife device 1 comprises a disc 2, Fig. 3 (not shown), clamped between cheeks 3, 4 and mounted in ball bearings, suspended by pivoted arms 7, 8 in a carrier 10 connected to a slider 11 displaceably mounted on a guide beam 12. Each carrier 10 has a vertical slot in which a spring 14 presses down on a sliding block 15 comprising a pivot 9. The spring operates to press the edge of a respective knife against two counter rolls 16, 17. The guide beam 12 may be of U-section housing the lazy-tongs 18, whose links are divided into sets of groups of six, with a free link at each end connected by a pin with a slider 11, which may be positively adjusted by one of parallel screws 19, 20, Fig. 5. Each screw-operated slider has a lug 24 on its top surface with a screw-threaded hole working as a nut on its respective screw. In the middle of the assembly is a member 11a fixed to the beam 12 with bearings for plain mid-length portions of the screws 19, 20, and means to prevent axial movement of the screws. The screws are geared together by gears 21, 22 operated by a hand wheel, and provided with series of threads of differing pitch and diameter, to permit control of different sets of knives. All the knives 1 can be moved into non- operative position out of engagement with the counter rolls 16, 17, for infeeding material, by operation of a hand lever 43 and a pivoted lever arrangement 33, 38, 39. Individual knives may be lifted into non-operative position by being turned about a bolt 9. The pressure of the knives against the counter rolls is adjusted by a screw 35 which varies the tilt of the beam 12 when screwed upwards. In a modification to permit adjustment of the spacing of the knives while maintaining uniform spacing, the screw arrangement is divided into halves 141, 142, Fig. 6 (not shown), held together by a ring 143, which permits relative rotation. The screw half 141 has a bore 144, through which a shaft 145 extends, having an adjusting wheel 146 at one end and a transverse key or wedge 147 at the other actuated by a spring 148 and engaged in a slot 149 in the screw half 142. The screw halves are normally in non-rotative connection with one another. When the key 147 is moved out of engagement with the slot the halves can be turned independently. In further modifications one or more screws may be used, and the knives may be other than discs and non-rotary.

Abstract: 555,527. Telephone instruments ; switches. STANDARD TELEPHONES & CABLES, Ltd. March 28, 1942, No. 4175. Convention date, Jan. 24, 1941. [Class 40 (iv)] [Also in Group XXXVII] The switch contacts of a telephone sub-set are so arranged in relation to a magnetic circuit which traverses the receiver and the base portion when the receiver is carried by the latter as to be operated by the change of magnetic flux which occurs when the receiver is removed. In the form shown in Fig. 1, the magnetic circuit is formed by soft-iron members 7, 8, a magnet 9, and the reeds 11, 12 of a magnetically-operated switch, all arranged in the support 5, together with a soft-iron member 6 in the hand-set 1. When the latter is laid on the support, as shown, part of the magnetic flux which otherwise passes through the reeds 11, 12 and causes them to close the contacts is diverted through the path which is completed by the member 6, thus causing the switch to open. In one modification the magnet bridges the lower ends of the members 7, 8 and the switch the upper ends, and in another the members 7, 8 are replaced by magnets, a softiron bar bridges their lower ends, and the switch occupies the position shown of the magnet 9. Other forms comprise a bar magnet and the switch, arranged one in the hand-set and the other in the support so that when the hand-set rests on the latter the magnet and switch are in close parallel relationship, causing the switch contacts to close. In the form shown in Fig. 5, in which the hand-set hangs on the support, a mercury type magnetic switch 28 is arranged between soft-iron pole pieces 29, 30 on a magnet 25, and a soft-iron member 6 in the hand-set diverts a portion of the flux through itself and through auxiliary polepieces 26, 27 when the hand-set is hung up, thus causing the contacts to open. Several switches may be operated sequentially by using switches of different sensitivities, or by locating them differently in the magnetic circuit.
