Title: Improvements in or relating to the production of pattern effects on mixed fabrics made of vegetable fibres and wool
IPC: D06Q1/02
Filed: 1938-09-05
Abstract: 518,293. Crape effects. AKT.-GES. CILANDER. Sept. 5, 1938, No. 25969. Convention date, Aug. 2. [Class 15 (ii)] Crape or relief effects are obtained on fabrics of vegetable fibres and wool by impregnating with a solution containing up to 10 per cent. of formaldehyde, acetaldehyde, or acrolein and then shrinking with alkali. If desired part of the wool may be dissolved away from the mixed fabric in parts prior to impregnation with the aldehyde. Soft wool-like effects are thus obtained. The treatment prevents the wool from becoming stiff or felted by action of the shrinking agent while the capability of shrinking of the vegetable fibre is not impaired by the aldehyde or acrolein. On mixed fabrics with a striped pattern a crepe effect is produced whereas when the pattern is formed by removing part of the wool, the treatment results in relief effects, with the woollen parts projecting from the ground texture. In an example, a mixed fabric of cotton and wool is printed with a paste containing caustic soda so as to remove the wool and form a pattern. After drying and steaming, the residue of the printing composition is removed by acid. The fabric is then impregnated with a dilute solution of formaldehyde. It is rinsed and dried and then subjected to shrinking by means of caustic soda solution. A relief-pattern is thus obtained.

Title: Improvements in or relating to the manufacture of abrasive coated sheet material
IPC: B24D11/00
Filed: 1938-09-05
Abstract: 518,833. Abrasive coated sheet material. TENNANT, W. J., (Carborundum Co.). Sept. 5, 1938, No. 25972. [Class 60] Abrasive coated sheet material is made by attaching abrasive granules to a backing by means of adhesive, projecting a powdered adhesive on to the granule coated surface before the adhesive has set and simultaneously curing or setting both adhesives. The powdered adhesive may be projected or dispersed by means of an electrostatic field or by means of air under pressure. The adhesives may be heat hardenable phenol-formaldehyde condensation products. As shown in Fig. 1 paper or cloth 11 is coated with liquid adhesive by rolls 13, 14 and abrasive granules are applied from a hopper 17, Powdered adhesive from a receptacle 21 falls by gravity on to the abrasive coated web and is dispersed by the electrostatic field between a positively charged plate electrode 24 and a pair of negatively charged pipe or rod electrodes 26, 27. The'adhesives are then cured by passing the web through an electrically heated chamber 29. In the modification shown in Fig. 2 the abrasive granules are orientated during application by projecting them upwardly on to the adhesive coated web 32 by means of a feed belt 42 which is vibrated by rotating cams 48. Powdered adhesive from a receptacle 52 is carried on a feed belt 53 below the web and is dispersed by the negatively charged electrodes 58, while a positively charged electrode 59 above the' web attracts the particles into engagement with the granule coated surface. In the finished products the tips of the abrasive granules are free from adhesive. Specification 473,619 is referred to.

IPC: D06F37/36
Filed: 1966-06-10
Abstract: 1,140,607. Change-speed gears. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 30 March, 1967 [10 June, 1966], No. 26026/66. Headings F2C and F2D. A two-speed gear for a washing machine comprises an axially fixed internally coned friction clutch member 9 which is driven from an input shaft 2 by way of reduction gearing 3, 4, 5, 8 and is engaged by an externally coned surface 10a of an output clutch member 10 which is urged into engagement with the clutch member 9 by springs 17. High-speed drive is provided by an externally coned friction clutch member 11 helically threaded on the input shaft so as to tend to screw into engagement with an internally coned surface 10b of the output clutch member, but prevented from so doing by a baulk ring 18 having limited rotary movement relative to the clutch member 10 and to an axially fixed output member 15, and normally biased by springs 22 to a position in which internal teeth 30 of the baulk ring overlap teeth 31 on the output member 15 so that axial movement of the baulk ring 18 and thus of the clutch member 11 is prevented. High-speed drive is engaged when an electromagnet is energized, under the control of a programme sequence time switch, to apply a friction brake to the ring 18 which then rotates slightly against the bias of its springs 22 to bring its teeth 30 into register with the slots between the teeth 31 so that the ring 18 and the clutch member 11 can shift axially. The clutch member 11 engages the output clutch surface 10b and shifts the clutch member 10 to disengage the clutch 9, 10. The axial movement of the clutch member 11 on starting is provided by the inertia of the member as rapid acceleration takes place. For a change of ratio during running of the mechanism axial movement of the member 11 is produced by a retarding torque produced by frictional, viscous or aerodynamic drag.

Title: Improvements in retarding or pressure-controlling devices
IPC: B21D24/02
Filed: 1932-09-22
Abstract: 406,392. Shock-absorbers; cupping. CARTER SHOCK ABSORBER CO., Ltd., and CARTER, A., Oldbury Road, West Bromwich. Sept. 22, 1932, No. 26331. [Class 83 (iv).] A buffer 1, especially for a cupping press, on compression discharges fluid (oil) from the cylinder 3<a> through a pipe 7 and through overlapping orifices 18 and 24, the effective area of which can be set by hand to give a desired fixed resistance or an increasing or diminishing resistance during depression of the buffer. The oil passes from the orifices 18-24 to an annular space 26 and up through apertures 35 to the top of cylinder 10 where it presses on top of the piston 11 so that the piston 11 is forced down and draws down with it the attached sleeve 23 in which is the slot 24. The slot 24 is long enough to overlap the orifice 18 throughout this downward movement. To diminish the effective orifice and so alter the constant resistance the sleeve 23 is rotated a little to bring the slots 23-18 slightly out of register, rotation being obtained by screwing upper and lower blocks 43, Fig. 6, to one side by nuts 49. This moves cam slot 38 bodily sideways which moves cam roller lever 36 and so turns the shaft 32 carrying the toothed segment which thereby rotates the sleeve. To get a progressively increasing resistance of the buffer the slot 38 is inclined by screwing the lower block 43 to the left so that the sleeve 23 and its orifice 24 is gradually turned during descent of piston 11 to lessen the effective orifice by slight rotation of the shaft 32 and its gearing to the sleeve 23. To get a progressively diminishing resistance the cam slot 38 is inclined by screwing the top block 43 to the left. When the pressure on the buffer is relieved, the spring 12 forces up the piston 10 and the oil above it is forced through opening 35, annular space 26, apertures 20, and chamber 19, then lifting valve 21 and passing through sleeve 17 and pipe 7 to raise the draw ring or buffer 1. A spring 5 supports the weight of the draw ring 1 &c. To set the press tool the plunger 3 is held depressed, but to prevent this causing a pressure on the fluid and so possible leakage the valve 16 is opened to allow the displaced fluid to pass to a tank 14 and on releasing the plunger 3 after tool setting, oil flows back from the tank 14 through the valve 16 to re-close the plunger 3 to normal position, after which the valve 16 is closed. The spring 5 may be eliminated so that the plunger may have to be reset by a hand pump in the tank 1 . Oil leakage past the plunger 3 is led by pipe 55 to the sump 13 and leakage from the piston 11 also drops down into the sump 13 from which it is pumped up through the hole 62, passage 63 and valve 65 to the pressure oil in the space 26. This pump comprises a fixed piston 56 over which the cylinder 25 moves during working of the piston 11. Specification 353,165 is referred to.
