Abstract: 391,026. Sewing-machines. SPENCE, BRYSON, & CO., Ltd., Clonavon Factory, and GRACEY, S., 49, Castle Street, both in Portadown, Northern Ireland. Sept. 24, 1932, No. 26581. [Class 112.] Hemstitching and like machines have a device for automatically stopping the machine on exhaustion or breakage of thread or when the sewing is defective. In the form shown, a feeling edge 1b is adapted to bear against the edge or stitching of the hem E, the extension 1a keeping the projection 6a on a cam 6 out of the path of movement of a member 13, thereby allowing the machine 5 to run. When the thread gives out or breaks or the sewing is defective, the feeling edge 1b moves into the hem and the member 6, no longer held by the extension 1a, swings inwardly, allowing the projection 6a to come into the path of movement of the member 13, which moves the member 6 downwards, thereby swinging the member 7 round against a spring 7c and allowing the projection 9 on the rod 10 to pass up from the slot 7a to the slot 7b. This allows the member 11 to move upwards and operate the friction cone 12 through the projections 11a, 12a to stop the machine. The device is adjusted for different thicknesses of cloth by the screws 3. The stopping device is operated manually by lifting the projection 17 on the member 7. The machine can be run normally without having the stopping device operative by turning it bodily round the pivot 4a by the handle 22.

Filed: 1919-10-30
Abstract: 155,087. Fine Cotton Spinners' & Doubler's Association, Balls, W. L., and Hutchins, F. Oct. 30, 1919. Addition to 119,693. Fibres, separating and sorting. - A handoperated device of the kind described in the parent Specification, which can be used for grading small samples of fibre according to length, comprises a pair of delivery rollers C, C<1>, Figs. 1 and 5, operated through gearing e<2> from a pair of driving-wheels E which rotate as the device is moved along the flat plush collecting-surface G. The feed rollers A - - A<3> are carried in a frame D, which is pivoted on a stay-bar b of the frame carrying the delivery rollers and can oscillate to carry the feed rollers to and from the delivery rollers. The roller A<3> is pressed by a spring F against the first feed roller. The roller A<1> is carried in slots in the frame and the :roller A<2> is carried by an auxiliary frame D<2> pivoted at d. As the device is moved along the surface G, the rollers C, C<1> deliver the tuft of fibres received from the rollers A, A<2> and position them on the surface according to their length. At the end of the traverse, a pin M on the frame D enters a slot k in a cam K, Fig. 8, rotating with one of the gears e<2> driving the auxiliary rollers. This allows the frame D to move forward and brings the feed rollers near to the delivery rollers. It also stops rotation of the delivery rollers. Before repeating the traverse along the surface G, the frame D is lifted by a spring controlled handle H' and the pin M is removed from the slot in the cam. A spring detent K<1> is moved to cover partially the slot k and prevent the return of the frame. When the handle is released it rotates the feed rollers through a pawl and ratchet arrangement to pass forward a new tuft of fibres. The delivery roller C<1> is pressed against the roller C by a, spring frame controlled by a cam lever G<1>. The feed rollers A are set slightly apart from one another so that the fibres can be drawn through them by the delivery rollers, and they are prevented from rotating whilst this is being done by a locking-pawl on the operating ratchet.

Title: Improvements in or relating to the recovery of oxalates and other organic substances
IPC: C07C51/47
Filed: 1923-10-25
Abstract: Oxalates, such as calcium oxalate, and other organic compounds occurring or formed in vegetable products, such as the bark of Terminalia Arjuna or the flesh of plants of the genus Opuntia, are recovered therefrom by passing the material in the form of an aqueous pulp over a selecting surface to which the desired organic compound tends to adhere.  Such a surface may be, for example, crepe rubber, woollen blanket, or the surface of rough-sawn wood. The pulp may first be passed through a sieve to remove part of the cellulosic matter, which may have been opened out by treatment with reagents such as sodium hydrate or carbonate.  The pulp may be treated also with reagents such as sesame oil which tend to prevent undesired material adhering to the selecting surface.  The process may be applied to natural products containing soluble organic acids, such as tartaric or citric acid, such products being treated with reagents, such as alkaline earth salts, to precipitate insoluble salts which are then recovered by the process described.  In an example describing the separation of calcium oxalate from the bark of Terminalia Arjuna, the selecting surface is crepe rubber which covers the surface of a belt lying more or less horizontally below the stream of pulp flowing from the sieve.  The oxalate particles adhere to the belt, while the remainder is carried away by the flow of the pulp assisted, if necessary, by water jets playing on the belt.  The belt moves in the opposite direction to the flow of the pulp and carries the oxalate particles to a point where they can be removed. The belt may be given a lateral or other shaking movement, and may have a riffled surface.  The selecting surface may alternatively be arranged on a moving disc, on the periphery of a wheel, or inside a tumbling barrel.  Specifications 201,131 and 227,924 are referred to.
