Title: Container and Method of Forming the Same
IPC: B65D55/08
Filed: 1967-03-02
Abstract: 1,181,833. Container closures; portable containers. AMERICAN CAN CO. 2 March, 1967, No. 10016/67. Headings B8D and B8T. The end seam 34 of a tubular container is released by means of a strip 14 the lower part of which is adhered at 20 to the body 10 of the container before an end closure 26 is applied and crimped to hold the upper part of the strip. A line of weakening 24 curves down at 25, Fig. 4, short of a tab 22 loosely adhered to the overlapped strip at 23, so that on pulling the tab 22 the strip tears along the line 24 and at the same time the upper part of the strip is pulled free from the seam 34 thereby freeing the end closure 26. In a modification, Figs. 5-8 (not shown), the weakening line 24 is omitted so that the whole of the strip is removed when the tab 22 is pulled. Again, Figs. 9-16 (not shown), the strip 14 may be formed of extensible material so that when the seam (240) is formed the strip material is constricted, yet when the tab (242) is pulled, the thicker portion of the strip above the pinch of the seam elongates and thereby can be drawn out from the seam. The ends of the strip 14 may not overlap. The container may be filled through either end after which the respective end closure is applied. Materials.-The container body may be of fibre convolutely or helically wound; of plastics; of sheet metal, e.g. aluminium or tinplate; or of glass. The end closure may be of metal, and the strip 14 of plastics, metal foil-backed paper, or plastics film-backed paper. The body may have liner and label plies of metal foil or plastics film.

Title: Improvements in the manufacture of cellulose acetate
IPC: C08B3/06
Filed: 1932-04-08
Abstract: Substantially completely acetylated cellulose acetate is made by preheating the cellulose at a fairly high temperature with a mixture of acetic acid and acetic anhydride in presence or absence of an added catalyst, and subsequently adding further acetic anhydride and acetylating the cellulose in presence of a catalyst in the same bath by allowing the temperature to rise and maintaining the temperature until a clear homogeneous dope is obtained, not more than three parts of acetic acid and three parts of acetic anhydride per one part of cellulose being used in all. The initial temperature may be 100 DEG F., and may be allowed to rise 120--150 DEG  F. and kept at this temperature.  The amount of acetic anhydride is preferably not less than the theoretical proportion, and not more than 2.5 parts in all. Part of the acetic acid may be replaced by a solvent such as ethylene chloride, chloracetic acid, or alkyloxyacetic acid.  The process may be carried out in presence of sulphuric acid as a catalyst.  An alkali metal salt such as sodium sulphate, phosphate, or acetate may be present during the acetylation, and may be added before the pretreatment, products of improved viscosity in acetone dopes being obtained when such additions are employed.  The acetic anhydride employed may be of 85 per cent strength.  Cheap cellulosic materials such as bagasse, wood pulps, esparto, grass products, and corn stalks may be treated by the process, the material preferably being free from liquor and other encrusting substances.  Instead of hydrolyzing the reaction product, the acetate may be precipitated directly therefrom by means of water or methyl alcohol.  The product is soluble in acetone or ethylene chloride-alcohol. Specification 364,794 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the application of the above method to the partial acetylation of cellulose.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1515911 Electronic timepieces SOC SUISSE POUR L'INDUSTRIE HORLOGERE MANAGEMENT SERVICES SA 23 Feb 1976 [12 March 1975] 10310/75 Heading G3T [Also in Division H2] In an electronic timepiece having a stepping motor driving a time display, it is arranged that the motor drive pulses are not supplied directly from a battery P but from a capacitor C which is charged from the battery in the intervals between motor steps. The timepiece (Fig. 1) comprises an integrated circuit CI including an oscillator followed by a frequency divider and continuously energized by the battery P to provide low frequency pulses to control the motor drive circuit including switches 1-5 (e.g. M.O.S.-F.E.T.s). The cycle of operation is as follows:- (1) switches 1, 2 are closed and 3, 4, 5 opened so that capacitor C is charged in one direction via a resistor R; (2) switch 5 is closed, and the switches 1-4 opened so that capacitor C discharges through the motor winding LM in one direction to advance the motor by one step; (3) switches 3, 4 are closed and 1, 2, 5 opened so that capacitor C is charged in the opposite direction; (4) switch 5 is closed and switches 1-4 opened so that capacitor C will discharge through winding, in the opposite direction to that of stage 2, to advance the motor by another step. The cycle is then repeated. Since the motor winding and capacitor form an oscillatory circuit their component values are selected so that a halfperiod of oscillation is equal to the duration of one step of the motor. A non-polarized capacitor, e.g. tantalum type, is used.

Filed: 1929-04-03
Abstract: 318,987. Keen, T. A., and Smith, H. M. Sept. 14, 1928, [Convention date]. Dog-racing apparatus.-An electrically - propelled lure carriage runs upon a single lower rail and is steadied bv an upper rail, the circuit passing through both rails. The two carriage wheels 34 mounted in side plates 32 run on a lower rail 23, the arm 36 of the lure 37 having a portion 39 upon which is a fixed insulating ring 41 forming a bearing for a wheel 40 which bears against the upper rail 26. An insulation disc 42 separates this wheel from the side plate 32. The current, which is direct current of low voltage. passes from a central storage battery to rail 26, wheel 40, thence by any suitable means to terminal 43 of motor 44 and from a second such terminal to wheel 34, rail 23, and back to the battery. The motor 44 drives the rear wheel 34 by bevel gears 47, 48, the rear wheel 34 driving the front wheel 34 by chain and sprocket 50, 51, 52. At the end of a race a points switch deflects the carriage to a siding having the braking means of Fig. 10. A portion 90 of the upper rail 26 is hinged at 91 and pressed downwardly by springs 93 so that the converging rails 90, 23 offer increasing resistance to the carriage wheels. This brake is raised for release by a cord 94. A gate which is moved across the course at the close of a race consists of a section 71 of the inner fence 70, Fig. 7, which is pivoted about a post 73 against spring 76 by an integral lever 75 and a cord 79 operated from the judge's box. Pulling on a second cord 81 causes a lever 82 and a part 74 to rotate. This part 74 is pivoted to the part 71 and when thus operated it is rotated to complete the closure of the course. By pulling on a third cord 84 a pivoted flap in the section 74 is raised and automatically propped up. When the lure arm passes, it knocks away this prop and the flap completes the closure acros the course.

Title: Improved device for indicating stretch or shrinkage in continuously moved lengths of material
IPC: G01B5/30
Filed: 1943-06-29
Abstract: 567,784. Stretching or shrinking cloth &c. PORRITTS & SPENCER, Ltd., and PORRITT, C. P. June 29, 1943, No. 10549. [Classes 42 (i) and 42 (ii)] A device for indicating stretch or shrinkage in continuously moved lengths of cloth &c. comprises indicators to measure the speed of the material before and after stretching &c., the indicators being inter-related to compensate for the difference in speed of the material before and after stretching &c., so that variations in the ratio of the speeds can be determined by inspection. A web of cloth &c. 1 is led over a measuring roller 2 between adjustable tensioning rollers 3, 4 to a drag roller 6 driven by worm gearing 7 on a shaft 9. A second drag roller 10 is driven by worm gearing 11 on shaft 9, there being an adjustable variable speed transmission 8 between gearings 7 and 11 to impart stretch to the cloth. The cloth from roller 10 is led over guides to the first roller of the tentering machine. A " clock " indicator 15 comprises two pointers, carried by concentric shafts, one shaft being driven by the measuring roller 2 and the other by the first tentering roller so that the different peripheral speeds thereof would normally result in a separation of the pointers. The gearing of the " clock " to the pointers admits, however, of the substitution of idler wheels so chosen that the pointers will show no separation on the " clock." A constant stretch ratio can then be maintained by adjustment of the gears 8. A worm reduction drive from the " clock " shows, on another dial, the total yardage of cloth passing over the roller 2. In a modification, differential gears driven in opposite directions are used for the " clock," an indicator being attached to the planet: wheel. Adjustment of the drive to one wheel enables a stationary indication to be obtained on the planet wheel.
