Title: Improvements in or relating to apparatus for charging the basket of a centrifugal machine, as used for curing sugar or other crystalline substances
IPC: B04B11/04
Filed: 1944-07-22
Abstract: 575,436. Centrifugal machines. WATSON, LAIDLAW & CO., Ltd., and INGLES, W. L. B. July 22, 1944, No. 14060. [Class 23] A basket 10 of a machine for centrifugally treating sugar, or other crystalline substances, is charged by a vessel 15 which is automatically filled and emptied by way of inlet and discharge valves 16, 17. The valves may be actuated pneumatically, electrically or manually, under control of apparatus such as is described in specification 569,485. The material in 15 is stirred by paddles fixed to a shaft 26, drivenby gearing 29, 30 and/or by a helical steam coil which is also used to heat the material. An adjustable air outlet pipe 37 is shut off when the material in 15 reaches the lower end of 37, thus forming an air pocket in the vessel which prevents the entry of further material. Alternatively, a flexible diaphragm or a float valve may be used to shut off the supply of material. The capacity of the charging vessel or mixer 12 may be adjustable, and it may be jacketed or lagged.

Title: An improved method of and apparatus for the manufacture of thread, yarn or filaments from rubber latex and the like
IPC: B29D99/00
Filed: 1934-05-12
Abstract: 442,935. Rubber threads. SHEPHERD, T. L., 7, Park Lane, London. May 12, 1934, Nos. 14437 and 24304. [Class 70] A process for producing rubber thread and the like consists in applying latex or like dispersion to a knife edge rotating member, applying coagulant, withdrawing the thread of treated latex, stretching it before it is fully coagulated, and completing the coagulation. As shown, latex from a bath 3 is applied by a disc 2 to the edge of a disc 1 dipping into a bath 4 of acetic acid or other coagulant. The thread in course of coagulation is pulled off by a roller 5 and then passes over a second roller which may run at a greater speed. In order to ensure the complete coagulation the pulling or tension roller may itself run in coagulant. The method produces a round thread. Specification 441,124 is referred to.

Title: Improvements in or relating to copolymers of vinylidene cyanide with alkyl vinyl ketones
IPC: C08F22/34
Filed: 1953-05-22
Abstract: Copolymers of vinylidene cyanide and an alkyl vinyl ketone are made by mixing the monomers, optionally in the presence of a peroxy catalyst and an organic solvent for the monomers.  The monomers, solvent, or catalyst, may be added continuously or intermittently during the reaction.  The monomeric vinylidene cyanide used is a crystalline solid at 0 DEG  C., has a melting-point of 9.0 DEG  to 9.7 DEG  C. and on contact with water at room temperature undergoes instantaneous homopolymerization.  The ketone may be methyl, ethyl, propyl, isopropyl, n-butyl, sec.-butyl, amyl, hexyl, octyl or decyl vinyl ketone.  Solvents mentioned are benzene, toluene, methyl toluene and trichlorobenzene.  The catalyst may be silver peroxide, a perborate, a percarbonate, benzoyl peroxide, caproyl peroxide, lauroyl peroxide, acetone peroxide, acetyl benzoyl peroxide, cumene hydroperoxide, o,o1-dichlorobenzoyl peroxide, 2,4-dichlorobenzoyl peroxide, o,o1-dibromobenzoyl peroxide, caprylyl peroxide, pelargonyl peroxide, t.-butyl hydroperoxide or tetrahydronaphthalene peroxide.

Abstract: 656,663. Ground anchors. REID, J. M. April 23, 1949, No. 14475/48. [Class 45] A ground anchor comprises a number of arms 2 each of which curve downwardly and outwardly and has a ground gripping or penetrating member 3 at its lower end, the arms being pivoted to a supporting post 1 so that each can swing in a plane radial to the common axis of the arms,. a plate-like expansion member 4 being positioned between the arms and connected to an operating rod extending upwardly through a tube 7 above it, a threaded. upper end 6a of the rod projecting from the tube and carrying a nut 8 provided with hand-turning means 8a and which bears on a disc 9 fitted to the upper end of the tube and which nut when screwed further on to the rod draws it through the tube to cause the plate member 4 to splay the arms 2 apart so that the gripping members 3 penetrate the ground. As shown two arms are used and each engages in a slot 5 in the plate 4. After the gripping members 3 have penetrated the ground the nut 8 and tube 7 are removed and by reversing the tube and replacing it on the rod the disc 9 may be used for tamping down the filling for the hole. After such filling and tamping any suitable screw adjuster is threaded on to the nut 8 to hold a guy rope or like. The plates 3 may be integral with the arms 2 and more than two arms may be used.

Abstract: 526,296. Photographic copying apparatus. KODAK, Ltd. May 18, 1939, No. 14821. Convention date, May 18, 1938. [Class 98 (i)] In a photographic copying apparatus a plate in the film gate is provided with an exposure opening the area of which is variable by a movable masking member which is operatively connected to indicating means which define the corresponding area of the photographic field on a copy-holder. In the apparatus shown, the copying camera 21 is mounted on the top of an open-fronted casing in the base of which is a rectangular recess or well 18 for the document to be copied. The film gate of the camera, Figs. 5, 6, comprises a channelled plate 28 over which the film F passes, being held down by rollers 43 on a pressure pad 42, Fig. 1. A masking member 32 is slidablv mounted in the channel of the plate 28, having a rectangular cut-away portion 35 one edge 32<SP>1</SP> of which forms a movable boundary of the adjustable opening of the film gate, the opposite fixed boundary 30<SP>1</SP> corresponding in position to the image of the front edge 19 of the copy-holder. The member 32 is automatically adjusted to correspond in position to the image of a strip 44 which forms a rear abutment for the copy and is adjustable to and from the front edge 19 of the copy-holder. For this purpose, the strip 44 is carried by brackets extending upwardly through slots in the floor of the copy-holder from a carriage movable along a guide strip 50 mounted in the hollow base. An endless sprocket chain attached to the carriage and passing round a front idler sprocket 53 and a sprocket on a shaft 56 at the rear of the apparatus causes rotation of the shaft as the strip 44 is adjusted, and a further chain 59 driven by a sprocket on the shaft 56 causes rotation of a second shaft 62 at the top of the casing. This second shaft carries a cam 64 which engages a follower on a lever 69, to which is adjustably secured an arm 66 connected by a link 65 to a lug 36 on the masking member 32, the masking-member being thus moved so that the edge 32<SP>1</SP> always coincides in position with the image of the strip 44. A recess 31 in the film gate permits standard data such as machine number, date &c. to be recorded. A curtain 76 attached to the strip 44 and to a spring roller 74 covers the part of the copy-holder not in the field of the camera, and prevents documents being placed there. Specification 490,899 is referred to.
