Title: Improvements in or relating to pneumatic type wheel rims
IPC: D01G15/84
Filed: 1947-05-07
Abstract: 632,325. Making wheel rims. BENSON, W. E. May 7, 1947, No. 12283. [Classes 83 (ii) and 83 (iv)] Stamping.-In a method of manufacturing pneumatic tyre wheel rims, a cylindrical shell is formed to a waisted blank comprising a central portion and frusto-conical flared ends, which is pressed between dies to deform it to the desired rim profile, wholly by imposition thereon of an axially-directed compressive loading applied to the ends of the blank by the dies. A waisted blank, Fig. 4, formed from a cylindrical shell, is compressed between dies 7 and 8 and a split annular die 6, to the finished form of Fig. 1. The outermost recesses in the dies 7 and 8 form the margins of the rim into solid compressed beads 5, or they may be arranged to form hollow beads about reinforcing hoops, particularly when the rims are made of a light material such as aluminium or aluminium alloy. In one form of apparatus, the die 7 is carried by a press ram and the die 6 is carried in a die gate 19 pivoted and vertically movable on a shaft such that as the die 7 descends and engages a blank held in the die 6, the die gate 19 is constrained to move downwards against a buffer until the die 8 engages the underside of the blank, further movement of the ram then serving to bring the faces 18 of the dies 7 and 8 together to complete the pressing. More than one die gate 19, 19a, may be provided so that as one completed rim is being removed another may be in position under the ram. Preferably interlocking means are provided so that the press ram operates only when one or other of the die gates 19, 19a is correctly disposed for a pressing operation. The wall thickness of all portions of the shell that have their diameter reduced, is increased so that the base wall 1 is thicker than the remainder of the rim.

Filed: 1966-03-21
Abstract: 1,134,897. Cine cameras. ELMO CORP. March 21, 1966 [Jan.31, 1966], No.12330/66. Heading G2E. A cine camera has a main body 100 which may be used with two or more magazines 200 containing film of different widths, such as double-8 and super-8, and includes a system for automatically inter-changing the film gate size in the aperture assembly 116 as a magazine is inserted into body 100. Assembly (116) includes a stationary member (122) secured to body 100 and a movable member (121), as in Fig.4 (not shown), biased towards a first position relative to member (122) to define one gate, but displaceable to a second gatedefining position. Member (121) is supported by and secured to the H-shaped spring (120) held between plates (111) and (118), and defines two film guiding surfaces by means of surfaces (126') and (129') of ridges (126), (129), to receive 8mm. wide film. Springs (131) on member (121) press the film against surface (126') and, together with member (132), enters aperture (136) in the stationary member (122) which is secured to plate (111). Apertures (130) and (137) in members (121), (122) are thus aligned. Projections (138), (139) beside aperture (137) fit grooves (133), (127) on member (121), ridge (142) on member (122) and ridge (126) define the width of double-run 8mm. film, while surfaces (140, 141, 142) of member (122) are flush with surface (129") of ridge (129). This is the normal operative position. Member (121) is moved to its second operative position by pressure on pins (135) on H-spring (120) as a cassette containing double-run film is inserted into the camera. Cassettes containing single-width 8mm. film have apertures to receive pins (135) so that spring (120) is not depressed. Ridge (126) on member (121) is now flush with surfaces (140, 141, 142). Fine adjustment of the separation of members (121), (122) is made by means of screws (145). As in Fig.1 motor 108 drives toothed wheels 110, 110' which engage corresponding wheels in a double-run cassette in both its positions whereby the film spools are driven. Beam-splitter 102 directs light on to photo-cell 104 controlling diaphragm blades 103.

Title: Production of insoluble cellulose derivatives
IPC: C08B15/06
Filed: 1943-08-04
Abstract: Cellulose derivatives, insoluble in organic solvents and infusible at high temperatures are obtained by dissolving a cellulose derivative containing free hydroxyl groups and a crystalline monomeric polyalkoxyalkyl melamine in a common solvent, removing the solvent therefrom, and subjecting the resultant mass to elevated temperatures to insolubilize the product.  Specified cellulose derivatives which contain free hydroxyl groups are cellulose esters, e.g. the acetate, formate, propionate, butyrate, acetate-propionate, nitrate, acetate-nitrate or ethers such as ethyl, benzyl or butyl cellulose. Melamine derivatives having two or more alkoxy alkyl groups substituted thereon, such as N.N1.N11 - tris - (methoxy-, ethoxy-, propoxy-, isopropoxy-, butoxy-, amyloxy-, isoamyloxy-, hexyloxy- and heptyloxy-methyl) melamines, or mixed ethers such as N.N1-bis-(ethoxymethyl)-N11-methoxyethyl melamine, or any dialkyl or trialkyl ether of tri- or dimethylol melamine may be employed.  The solution may be dry spun into fibres or cast into films and after removing the solvent therefrom the fibres or films are heated to insolubilize the product.  Suitable solvents are chloroform, ethyl acetate, dioxane, benzyl alcohol, b -ethoxy-ethanol, diacetone alcohol, acetone, chloroform-acetone, ethyl acetate-alcohol, benzene-alcohol and methylene chloride-ethyl alcohol.  Plasticizers and assistants such as dimethyl phthalate, dimethoxy-ethyl phthalate or triphenyl phosphate, and materials which hasten the subsequent heat treatment such as phthalicanhydride, phthalic acid, citric acid and ammonium iodide may be added to the solution.  The insolubilizing heat treatment may be effected by baking or by immersing the solvent-free product in an inert hot liquid, e.g. kerosene.  Numerous examples are given.
