Title: Improvements in or relating to methods of treating fabrics of natural cellulose fibres to improve the wash resistance of such fabrics
IPC: D06M11/38
Filed: 1964-02-17
Abstract: The wash resistance of fabrics comprising natural cellulose fibres, e.g. cotton and linen, is improved by impregnating them at a temperature of over 15 DEG C with an aqueous solution containing 5 - 20% by weight of sodium hydroside or an equivalent amount of potassium hydroside, winding the impregnated wet fabrics on to a roller and maintaining them in this rolled-up and wet state for a reaction time of more than 3 hours before the hydroside is rinsed out.  After impregnation with the aqueous solution of sodium or potassium hydroside which may also contain a wetting agent and an agent preventing fading of coloured fabrics, the fabric may be pressed to remove excess impregnating liquid, wound under tension on the roller, covered with a plastic film to prevent evaporation and the roll of fabric rotated during the reaction time to prevent the impregnating liquid from being irregularly distributed in the roll by gravity.  When rinsing out the hydroxide partial neutralization may be performed with the aid of a weak acid, e.g. acetic acid.  The fabrics may subsequently be bleached with sodium chlorite.

Title: Improvements in the preparation of compositions of rubber or the like and the incorporation therein of vulcanised rubber or the like
IPC: C08L19/00
Filed: 1942-05-15
Abstract: Vulcanized rubber in crumb or powdered form is mixed with unvulcanized rubber and the mixture is heated until the surfaces of the vulcanized rubber become softened by the action of the unvulcanized rubber.  The mixture may then be compounded with vulcanizing agents &c. or into rubber mixes.  One or more of the agents necessary for vulcanization, e.g. mercaptobenzthiazole, may be added to the mixture before the heat treatment and the remaining agents, e.g. sulphur and zinc oxide, added after the heating.  The mixing may be effected by mechanical means on rollers or in an internal mixer or by mixing the crumb or powder with a dispersion or solution of rubber, the dispersion medium or solvent being removed before the heating.  The heating may be carried out by heating in air or open steam or in a closed vessel heated electrically or by steam, or by applying heat from an extraneous source as described in Specification 553,710 during working between rolls.  In examples, the mixture is heated at 95-100 DEG  C. in air in a steam-heated oven for 5 hours, or in open steam at 60 lbs. pressure for 4 hours, or by working on rolls at 40-45 DEG  C., the stock passing round the rolls being heated by an electric radiator in front of one of the rolls. The unvulcanized rubber may contain plasticizing agents such as mercaptobenzthiazole or zinc naphthenate.  Specifications 296,395, [Class 70], 359,205, 438,868 and 517,609 also are referred to.
Patent GB-483775-A (GB)
Title: Improvements in and relating to photographic cameras
IPC: G03B7/12
Filed: 1937-03-08
Abstract: 483,775. Controlling exposures in photographic cameras. RISZDORFER, O. March 8, 1937, No. 6761. Convention date, March 7, 1936. [Class 98 (i)] In a photographic camera in which the setting of a light regulating device (shutter speed or diaphragm) is determined by a stop actuated by the measuring instrument of a photo-electric device a number of movable members is provided of which one is selected by the pointer to act as the stop. Fig. 1 shows one form in sectional elevation and Figs. 3 and 4 are sections through A-F, G-H in Fig. 1. The measuring instrument connected to the photo-cell F<1> has magnet 1, coil 2, and pointer 3 carrying a block 32. A number of members 9 is provided pivoted at 10 to a member 13, each with a spring 11 to press it against the plate 12. When the rod 4 is rotated by the knob 61 the roller 33 is oscillated between the inclined cheeks 59 and 60 rocking the lever 6 and plate 7 and pressing the block 32 against one of the members 9 to swing it about its pivot. Rotation of the rod 4 also oscillates the lever 37 about the fixed pin 29 by means of the eccentrically mounted pin 28. This lever is connected to the collar 24 pivoted on the pin 16 and carrying two spring blades 25. Also mounted on the pin 16 is the toothed sector 14 carrying an abutment 15 and engaging the toothed disc 17 operating the diaphragm. In operation the spring blades 25 would sweep the abutment 5 backwards and forwards, but the member 9 appropriate to the setting of the measuring instrument has been pressed out into the path of the blades to form a stop, and the abutment 15 takes up a position opposite to it. The diaphragm is thus set in accordance with the setting of the measuring instrument. Alternatively the device may be used to control the shutter speed. A modification is described in which flexure of the pointer 3 is avoided by moving both of the members corresponding to the members 7 and 13 simultaneously towards the pointer. In this modification the magnet 1 can be rotated to provide a zero adjustment to take account of initial conditions such as plate sensitivity.

Filed: 1926-03-12
Abstract: 249,152. Kignell, E. H., and Kignell, E. P. March 14, 1925, [Convention date]. Regenerators having the regenerating material or filling with passages therethrough terminating at two ends of the filling, are provided at each of these ends with continuously rotating valve devices adapted to conduct one or more fluids through a plurality of passages of the material and simultaneously to permit another fluid to pass through other passages of the material. As shown adapted for three different fluids the apparatus comprises a casing 1 through which passes one fluid a and which contains the regenerating material 2; arranged within this casing are an annular inlet 3b for a second fluid b supplied through a lateral pipe 5b, and a central circular inlet 3c for the third fluid c supplied through a lateral pipe 5c. Corresponding outlets 4b, 4c are provided and the inlet and outlets are governed by rotary valve discs 7, 8, having openings 10a, 10b, 10c, Fig. 2, for the three fluids a, band c respectively. Attached to the discs 7, 8 are radial plates 9 separating the openings and bearing against the regenerating material 2, and the discs are secured to a shaft 11 journaled in a central pipe 12 so that when the discs are rotated each part of the regenerating material will in turn be passed by the different fluids. The discs are given a slow continuous rotation as by providing vanes in the openings so that the discs are rotated by the fluids passing through the apparatus, or they may be driven from pumps, fans &c. used to force the fluids through the apparatus. The regenerating material may consist of metal, glass, brick &c. and may have the shape of plane or corrugated plates, pipes, balls &c. The passages in the regenerative material may or may not be axial and the openings in the two valve discs may be different in size, shape and position.

Title: Eccentric link motion for piston engines
IPC: F01L29/04
Filed: 1937-03-10
Abstract: 474,342. Engine valve-gear. MANSA, J. L. March 10, 1937, No. 7052. Convention date, March 10, 1936. [Class 122 (ii)] In a single-eccentric valve-gear, the free end 5 of the eccentric-rod 4 is constrained to move in a flat circular arc whose centre is adjustable so that the direction of its radii is not substantially altered. The non-adjustable point 11 on the rocking-beam 6 to which the rod is secured is pivotally connected to the valve. The beam 6 is fulcrumed adjustably at 7 to a lever 8. Small adjustments of the lever effect the cut off ; moving the lever 8 to the point 10 reverses the engine. The point 11 may be arranged on the other side of the lever 8 on an extension of the beam 6. The distance 7-5 relative to the crank throw is such that the point 5 traverses substantially a flat circular path. The valve reaches its top position when the eccentric has rotated through an angle v. Constructions are described which permit continuous variations of the-admission from the maximum cut-off in one direction to the maximum in the reverse direction without the mid-position of the slide valve being substantially altered. In the construction shown in Fig. 2, the valve-rod 21 extends below the beam 6 and the link 12 is directed downwards. The distances between the points 11-20, 5-3, and 7-9, are equal to one another. The arms 7-5 and 5-11 are so designed that the lever 8, rod 9, and link 12 are parallel. In a modification,. the point 7 slides in a curved slot designed, to prevent the mean position of the valve altering with variation of cut-off. In a further modification, the lever 8 is arranged above the beam 6 and the point 11 is arranged between the points 7, 5. The eccentric may be displaced, e.g. 180‹ relative to the crank.

Title: Improvements relating to connection between a tug-plane and a trailer
IPC: B64D5/00
Filed: 1944-04-17
Abstract: 578,862. Aircraft. MALINOWSKI, S. W. April 17, 1944, No. 7085. [Class 4] A rigid connection between a tug plane and trailer comprises one or more universal joints or hinges which either of themselves control the control surfaces of the trailer, or are so arranged with intercoupling of the control surfaces of the tug plane and trailer, that the trailer automatically adopts the angle of flight corresponding to the speed of the tug plane, whilst being free to move in either a vertical or a vertical and a horizontal plane with respect to the tug. Due to such connection, when the trailer moves out of alignment with the tug plane the control surfaces of the trailer may be operated automatically by rods, wires, gear wheels, or other mechanism to return the tug plane to its correct attitude, or the pilot may operate the control surfaces of both machines simultaneously. In the arrangement shown in Fig. 1, a trailer comprising two booms 1, 2, and a rear wing 5 is articulated at points A to a tug plane 7, lateral movement of the trailer being prevented by tie members 6. The rudders 3, 4, of the trailer are moved by the pilot simultaneously with the rudder 10 of the tug plane. In the form according to Fig. 2 the trailer is allowed free vertical and horizontal movement with respect to the tug plane by means of two beams 1, 2, universally attached at A to the tug plane and through vertical hinges B to the trailer wing 5, the control surfaces of the trailer being operated automatically upon displacement of the trailer relatively to the tug. In further constructions the tug and trailer planes are directly connected together by universal joints or through a rigid boom.
