Abstract: 445,787. Toothed gearing. LEA RECORDER CO., Ltd., and HORNER, J. W., Cornbrook Park Road, Old Trafford, Manchester. Oct. 18, 1934, No. 29800. [Class 80 (i)] [See also Group XIX] Means for converting movements into a function thereof comprises toothed cams having toothed and smooth portions operating in sequence during the continued rotation of the cams. The cam a drives the cam b so that the angular rotation of b equals that of a raised to the power 3/2. Part of the drive is performed by the cam surfaces J', g and part by the teeth c, d. The cams are balanced and this in conjunction with the surfaces e, h causes the cam b to follow the cam a for either direction of rotation of a. In a modification, the cams are arranged to give effect to two functions in succession.

Title: Method and device for wrapping prismatic articles
IPC: B65B11/32
Filed: 1934-10-18
Abstract: 426,309. Wrapping-machines. SCHWEIZERISCHE INDUSTRIE - GES., Neuhausen, near Schaffhausen, Switzerland. Oct. 18, 1934, No. 29872. Convention date, May 15. [Class 94 (i)] A square-angled package of bread, cake, biscuits, &c. is formed by wrapping the article or articles twice of more times with a single sheet of wrapping material, e.g. waxed paper. A double wrapping is effected by the use of three intermittently rotating wheels 7, 7<1>, 7<11> having pockets 4, 4<1>, 4<11>, for receiving the partially wrapped package. A plunger 3 thrusts the article 1 with the sheet of paper 2 into the pocket 4 at position A, the short flap 5 being folded over the outer side by a sliding member 8, and the long flap 6, which is to form the second wrapper, being folded thereover by a member 10 as the package moves to position B. Here one pair of end flaps 13, 14 are formed by sliding folders 11, 12, while the flap 17 is folded over them by a rotary member 15, the final flap 21 being folded down by a member 22 as the package moves to position C. Spring- pressed elements 18 on the folder 11 clamp the hanging flap 6 while the flap 13 is folded, so that tears are made at the adjacent points 20. The overlapping portions of the wrapper may be sealed by heating at position C, and at position D the package is transferred to the wheel 7<1>. The second wrapper 6 is folded over the outer side by a member 24 as the package passes to position F, and over another side as it is transferred to the third wheel 7<11>. A member 27 completes the folding of the second wrapper about the package during its passage to position H, and the end folds are made and may be heatsealed in the same manner as those of the first wrapper.

Abstract: 882,043. Ice-cream freezers. JERSEY CREME HOLDINGS PTY. Ltd. Aug. 31, 1960 [Sept. 14, 1959], No. 30063/60. Class 29 In a soft ice-cream freezer comprising a refrigerated cylinder 10 provided with a rotatable scraper-mixer 18 urging the mix towards one end which is closed by a member 27 provided with an outlet 41 and a discharge valve 44, the mix is caused to circulate past the valve 44 when it is closed to prevent an accumulation of hard frozen mix at the outlet 41. As shown, member 27 has a chamber 38 above the valve connected by passages 55, 56 to the cylinder space. Passage 56 feeds the hollow shaft 15 of the mixer assembly and the mix can pass therefrom back into the cylinder through aperture 57. Passage 55 opens on to a groove 58 in the inner face of member 27. Mix from the cylinder enters this groove through an aperture 28 in a disc 24 rotating with the mixer and is swept along the groove by a vane 32 mounted on the opposite part of disc 24 and enters chamber 38 through passage 55. When valve 44 is open, mix is impelled from the cylinder through passage 55 and chamber 38 to the outlet, but when the valve is closed it is returned through passage 56, shaft 15 and aperture 57 to the cylinder. A gear pump may force mix from the cylinder to chamber 38.

Title: An improved method of producing acetyl cellulose compounds and the artificial silk, bands, films and other artificial textile products, plastic masses and the like manufactured therefrom
IPC: C08B3/06
Filed: 1926-11-29
Abstract: 263,771. British Enka Artificial Silk Co., Ltd., (Assignees of Naamlooze Vennootschap Nederlandsche Kunstzijdefabriek). Dec. 24, 1925, [Convention date]. Cellulose acetates, and processes for making filaments and films therefrom.- The amount of water present in the acetylating mixture is adjusted before the acetylation by allowing the mixture of acetic anhydride and acetic acid or other diluent to stand at least 2 hours; the condensing agent is then added, and the mixture is finally allowed to stand for a further minimum period of one hour. By increasing the periods of standing the proportion of water is reduced, until after a total period of 10 hours the mixture is practically anhydrous. The viscosity of the acetates increases progressively with decreasing water content. Acetates giving very viscous solutions are produced when the acetylation is performed under anhydrous conditions. The moisture contents of the cellulose is exactly adjusted before addition to the acetylation mixture. In examples the mixture of acetic anhydride and acetic acid is allowed to stand for 6 hours, and for a further period of 2 hours after the addition. of sulphur chloride, cellulose containing 6 per cent of moisture being added to the mixture; the acetylating mixture is allowed to stand for 2 hours and for a further one hour after the addition of sulphuric acid, and to the mixture cotton containing 4.5 per cent of moisture is added. The acetates obtained may be used for the manufacture of artificial silk, films, plastic masses, &c. The Specification as open to inspection under Sect. 91 (3) (a) refers to the adjustment of the water content of the acetylating mixture by allowing it to stand with or without the addition of the catalyst, for the requisite period of time, depending on the desired viscosity of the acetate. This subject-matter does not appear in the Specification as accepted.
