Title: Improvements in or relating to camera shutter mechanisms
Inventor: VINTEN CHARLES
IPC: G03B9/34
Filed: 1961-09-27
Abstract: 991,727. Camera shutters. W. VINTEN Ltd. Sept. 20,1962 [Sept. 27,1961], No. 34758/61. Heading G2A. A roller blind shutter comprises two endless bands 2 and 4, one within the other, each band having a wide aperture and at least one narrow aperture, each band intersecting the focal axis of the camera twice, the narrow apertures of inner and outer bands being in alignment at the same time as the wise apertures are in alignment so as to provide an exposure aperture along the focal axis from lens to film. In Fig. 1 the wide aperture 11 is visible on the inner band 2, which is narrower than the outer band 4, in which four narrow apertures 10, of varying width, are shown in Fig. 1. Fig. 2 shows the narrow aperture 14 of the inner band behind the narrow apertures 10 of the outer band. The outer band can be moved relatively to the inner band so that each narrow aperture 10 can be placed selectively in alignment with aperture 14 to form an exposure slit of different width. As shown, both bands are in contact between rollers 24, 26, during which the scanning exposure of the film is made. After leaving roller 26, the bands diverge to pass round rollers 28 and 30 respectively. From here, they pass round opposite sides of a drive member 32 and then round the same side of a drive member 36. Drive member 32 has a sprocket roller 52 for driving the inner (narrower) band, while the outer band rides over end rollers 54. Conversely, drive member 36 has sprocket rollers 62 for driving the outer band, the inner band riding over an idling cylinder 64. The two bands then pass over guide members 38 and 44 back to the exposure section. Normally the two bands are driven in synchronism, the motor 70 driving by means of gear-wheels 74, 76, 78, 80 the respective shafts 79, 82 of the drive members 32, 36. In order to vary the size of the exposure slit, the sprocket 52 can be uncoupled from the shaft 82 by means of a spring-loaded knob 84, so that sprocket 62 can be rotated relative to the stationary sprocket 52, i.e. one band is moved relative to the other. In Fig. 4 this relative movement can be adjusted in a number of discrete steps, but Fig. 5 (not shown) illustrates a differential mechanism for effecting a continuously variable adjustment. Fig. 6 (not shown) is another mechanical arrangement for varying the relative position of the bands, and hence the effective slit width. The bands may be driven at a constant speed, but it is preferred to drive them in a "pulsed" manner, accelerating to operating speed just prior to the exposure.

Title: Improvements in bottle caps and the method of making the same
IPC: B21D51/50
Filed: 1922-12-21
Abstract: 203,976. Thompson, W. P., (Bernandin Bottle Cap Co.). Dec. 21, 1922. Caps.-A one-piece deep-drawn bottle-cap having on its outer surface a coating liable to be injured by the usual methods of deep drawing is formed by coating the sheet of metal, from which the cap is to be drawn, with lacquer, enamel, &c., cutting a blank therefrom, and securing it, by a spring-pressed washer 11, Fig. 4, in 'a female die 7. This die has a drawing ring 9 with a curved drawing face 10, and with it co-operates a male die 8. Beginning at the part which is to form the top and progressing towards the edge the cap is drawn from the blank by a drawing contact which is limited to a small fraction of the depth of the cap to minimize the drawing strain, and the metal is so supported that the entire re-shaping is formed by a flowing of the metal. When the depth of the cap is to exceed half the diameter thereof, the shell thus produced is subjected to a similar operation by placing it on a sleeve 14, Fig. 6, surrounding a male die 15 which co-operates with a drawing ring 13 on a female die 12. After the cap is drawn, it is knurled, screw-threaded, and trimmed.

Abstract: Partially hydrohalogenated interpolymers are derived from rubbery interpolymers of a major proportion of an isoolefin containing from 4 to 8 carbon atoms and a terminal methylene group with a minor proportion of a polyolefinic hydrocarbon, said hydrohalogenated interpolymer retaining some olefinic unsaturation and having a halogen content of from 0.1 per cent of fluorine, chlorine or bromine up to 1.0 per cent equivalent of fluorine, in the structure <FORM:0737447/IV (a)/1> Isoolefins specified are isobutylene, 3-methyl or 2-ethyl butene-1, 4-methyl or 4-ethyl pentene-1 or mixtures and polyolefins tabulated include acyclic and alicyclic conjugated and non-conjugated diolefins, acyclic and alicyclic triolefins, tetra- and penta-olefins and polyolefinic hydrocarbons containing aromatic nuclei.  Other monomers such as styrene, chlorostyrene and acrylyl and methallyl chlorides may be copolymerized with the isoolefin and the polyolefin.  The hydrohalogenation may be carried out in solution, dispersion or cement or by passing gaseous hydrogen chloride or bromide over the solid interpolymer. Solvents specified are toluene, chlorobenzene, methyl and ethyl chlorides, trichloroethane, carbon tetrachloride, butane, hexane and heptane.  Solvents may be subsequently removed by running the solution, e.g. stabilized with an epoxidized diester of cotton seed fatty acid, into water containing a colloidal protective agent such as zinc stearate.  The products may be admixed, by blending dispersions, latices or solutions, with natural or synthetic rubbers and these mixtures or the products alone may be compounded and vulcanized with the usual ingredients, particularly by means of zinc oxide and carbon black.  The hydrohalogenated interpolymers may be used as adhesives, for the manufacture of inner tubes and tyre curing bags and in bonding non-hydrohalogenated interpolymers, natural rubber and synthetic rubbers such as butyl rubber.ALSO:A composition comprises natural rubber and a partially hydrohalogenated interpolymer of a major proportion of an isoolefin containing from 4 to 8 carbon atoms and a terminal methylene group, with a minor proportion of a polyolefin, said hydrohalogenated interpolymer retaining some olefinic unsaturation and having a halogen content of from 0.1 per cent of fluorine, chlorine or bromine up to 1.0 per cent equivalent of fluorine, in the structure <FORM:0737447/V/1> The compositions may be obtained by blending dispersions, latices or suspensions and may be compounded and vulcanized with the usual ingredients and also with bivalent metal oxides, in particular zinc oxide in the presence of carbon black, to give products of improved physical properties.  Examples 11 to 15 describe the use of the hydrohalogenated interpolymers as adhesives (in heptane solution) for bonding butyl rubber to natural rubber.
