Title: Improvements relating to the ageing of footwear
IPC: A43D8/52
Filed: 1934-04-28
Abstract: 436,598. Breaking-in new footwear. WOOD, K. L., 12, Addington Road, Sanderstead, Surrey. April 28, 1934, No. 12909. [Class 17 (i)] An apparatus for ageing or breaking-in new or uncomfortable footwear comprises an artificial foot on which the footwear is mounted, having a toe portion connected by a flexible joint to a rear portion. A platform or other supporting surface is mounted so that relative movement is produced to bend the toe of the footwear relatively to the rear part, a spreading movement of the shoe upper in the vicinity of the metatarsal arch of the foot being effected before the bending of the toe part occurs. As shown in Figs. 1, 3, 4, the artificial foot comprises a toe part n pivoted to the main part a, a stiff blade-spring o resisting movement. A pair of cheeks p are pivoted at q at the sides of the part a, and are spread apart against the action of a connecting spring r by the engagement of an adjustable wedge t carrying rollers u which contact during the operation of the device with wedge members s on the cheeks h. This spreading movement takes place before the bending movement of the toe and until lost motion between the foot and a lever b is taken up. The toe part may, in order to avoid abrupt projections on the artificial foot, also be provided with pivoted side portions which may be spread outwards when the cheeks p are expanded. An upstanding heel bracket y on the foot a is connected by a coiled spring z to the lower end of a lever b to which the part a of the foot is pivoted at v and which is oscillated by a crank operated lever g, Fig. 1, pivoted to it at h. Dry or moist heat may assist the ageing process. If desired, the artificial foot may be mounted on a fixed support and the platform or other co-operating member may be given a sliding or up-and-down motion, and may then be used in conjunction with a number of artificial feet.

Patent GB-231807-A (GB)
Title: Manufacture of cellulose derivatives
IPC: C08B11/08
Filed: 1924-05-30
Abstract: Cellulose derivatives soluble in aqueous alkalies but insoluble in water and the usual organic solvents, are obtained by acting on cellulose or an alkali-insoluble cellulose conversion product with a halohydrin of a polyalcohol or a derivative or internal anhydride of such halohydrin, in the presence of an alkali solution of not more than 30 per cent strength, preferably up to 25 per cent strength. Halohydrins of glycerol or glycol such as a -monochlorhydrin and ethylene chlorhydrin are suitable; the monohalohydrins are preferred. According as the alkali solution is weaker, so a larger excess of halohydrin is permissible. The derivatives so prepared are distinguished by their inertness, their resistance towards alkalies, their durability, and the flexibility and the transparency of the products made from them; and they are suitable for the manufacture of artificial threads, films, plastic compositions, coatings, finishes for textiles, sizes, thickening-agents for textile printing, and fixing-agents for pigments. The treatment of the cellulose with alkali and halohydrin may be carried out simultaneously or successively in either order; the cellulose may be impregnated or kneaded with the aqueous or alcoholic solution of caustic alkali, and, if necessary, the excess of solution removed; the halohydrin is added in an undiluted state or diluted with water, ether, alcohol, etc.; the reaction proceeds without extraneous supply of heat, although the alkali-cellulose may be heated prior to or during the addition of the halohydrin; contact substances such as copper, silver, iron, or benzoyl superoxide may be added. The reaction mixture may be worked up into technical products after the addition of water or caustic alkali solution in order to effect solution of the cellulose derivative; or the latter may first be isolated by washing with water or aqueous alcohol, with or without previous neutralization or acidification. When working up the products it is convenient to effect fixation by dilute acid or any other precipitating-bath used for viscose. Specifications 166,767, 177,810, 203,346 and 203,347 are referred to.  The Specification as open to inspection under Sect. 91 (3) (a) includes the use in the above process of alkali of a strength up to 50 per cent.  This subject-matter does not appear in the Specification as accepted.

Filed: 1936-05-13
Abstract: 475,167. Arc lamps. CHANCE BROS. & CO., Ltd., and HARRIS, R. C. May 13, 1936, No. 13514. [Class 39 (i)] [Also in Group XI] In a searchlight or like light projector, two pairs of electric arc carbons e are carried by a carrier a which is capable of angular movement as a whole so as to bring either pair of carbons into the focus f of a reflector c without involving movement of any part of the reflector. The focus of the reflector may lie on its central axis or on an axis passing through a point at or near its periphery. In the form shown, the carrier a is in the form of a frame journalled in bearings b and rotated about an axis substantially parallel with the axis of the reflector by means of a hand-wheel g. Alternatively, or in addition, automatic means may be provided for rotating the carrier when one pair of carbons has been consumed. The carbons e, carried by holders d, are rotated and fed by means of an electric motor h. The latter operates a worm gearing i and a driving member j of a clutch adapted to engage either one of a pair of driven members k under the action of springs m arranged between the members k and a pair of sprocket wheels n on a pair of slidable and rotatable coaxial shafts l. The wheels , n drive chains o which rotate the holders d through sprocket wheels p and bevel gearing q. The clutch is automatically actuated, when the carrier a is rotated, by means of a ramp or cam surface on the projector coacting with a roller s on one end of either of a pair of slidable rods r to impart sliding movement to the rod, against the action of a spring n so that a wedge-shape fork t coacts with an abutment v on one of the shafts l. The latter may be extended to carry handles for hand operation. A red lamp or other indicator may be used to show that a change-over has taken place. An extension of the carrier is provided with separate pairs of main contacts w for connecting either pair of carbons c to a source of electric current through a single pair of brushes x, the arrangement being such that only that pair of carbons which is in the operative position is active. If it is desired to strike and stabilize the new arc before it is moved to the working position, provision may be made for both pairs of carbons to be alive simultaneously for a short period. The carrier may also carry a striking coil and any necessary relays. Specification 310,514, [Class 75 (iv)], is referred to. The Provisional Specification refers to sliding, swinging, or oscillating the carrier between stops.
