Abstract: 1,134,235. Copolymers of unsaturated esters of galactose. MILK MARKETING BOARD. 10 May, 1967 [18 May, 1966], No. 22069/66. Heading C3P. A copolymer is derived from a vinylidene or vinyl monomer and an ester formed by reaction of an alpha, beta-olefinically unsaturated mono- or di-carboxylic acid with the hydroxy group in the 6-position of galactose. The galactose ester is formed by reacting a 1,2,3,4-diketal of galactose with the unsaturated acid and the diketal residues may be removed from the copolymer by hydrolysis. Specified vinyl and vinylidene monomers are styrene, acrylonitrile, alkyl acrylates and methacrylates, vinyl acetate and vinyl chloride. In Examples 1 to 4, methyl methacrylate is copolymerized with diisopropylidene galactose methacrylate in bulk using azodiisobutyronitrile as catalyst. A similar method is used in Example 7 for the copolymerization of acrylonitrile with diisopropylidenegalactose acrylate and in Examples 9 to 11 for the copolymerization of styrene with diisopropylidenegalactose methacrylate. In Examples 5 and 6, methyl acrylate is copolymerized with diisopropylidenegalactose acrylate in an aqueous emulsion containing sodium lauryl sulphate and ammonium persulphate. Vinyl acetate is copolymerized in Example 8 with diisopropylidenegalactose methacrylate in solution in benzene with azodiisobutyronitrile as catalyst. The copolymers are hydrolysed with formic acid and water and, in some cases, the phenylhydrazone derivatives are then formed.

Title: Improvements in or relating to the utilization of exhausted sugar-beet slices, waste brewery and distillery grains
IPC: A23K1/14
Filed: 1921-10-28
Abstract: 195,911. Rigby, I. Oct. 28, 1921. Film evaporators; multiple-effect apparatus; vapours, utilizing for effecting further evaporation.-Sugar beet or grain is sliced or crushed, treated to obtain a sugar solution or an extract for brewing or distilling, and the exhausted material is converted into a dry product suitable for cattle-food or other purposes, the exhausted material is being rendered semi-fluid by pulping to bring it into suitable condition for distribution as a thin uniform film on the heating surface of a film drier, and then dried in apparatus of the kind described in Specifications 149,055, 180,963, or 181,035, in which the vapour from the film being dried is used for heating another area of film-drying surface. The water-content is reduced from about 70 to 10-15 per cent, or to such amount as will prevent harmful fermentation. The pulping process may be effected or completed in the drier itself, by introducing the material between two rotating drying drums having different peripheral speeds, as described in Specifications 178,636 and 180,963. When a suitable agglutinant material is available, the pulping may be wholly or partly dispensed with. This form of the process is adopted in treating distillery water which comprises solid husks or grains in suspension in a wash containing up to 3 1/2 per cent of dissolved solids. The draff, consisting of the solid husks or grains after separation from the wash, contains 70-80 per cent of moisture. The wash is concentrated and separated from suspended matter, and the semi-solid concentrate is mixed with draff, the draff itself or the mixture being pulped or not as desired, and the mixture is dried in apparatus of the type referred to above. In both forms of the invention, the drying may be completed in a different type of apparatus, the dried material may be used in its caked form as cattle food, or it may be compressed with or without a binding agent. Other food material such as molasses may be added, preferably before the film-drying. Instead of mixing the semi-solid concentrated wash with the wet draff, the draff mav first be dried and a more thoroughly desiccated concentrate then mixed with it to form the cattle food.

Title: Improvements in embroidery frames
IPC: D05C9/06
Filed: 1937-08-12
Abstract: 480,089. Embroidery-machines. WURKER, C. Aug. 12, 1937, No. 2218]. Convention date, Sept. 3, 1936. Addition to 421,700. [Class 112] The embroidery frame described in the parent Specification is modified by movably arranging the plates'set by the jacquard card on the carriage and providing them with projections which, according to the setting of the plates, come into engagement with levers during the movement of the carriage in one direction to operate the totalling member. In the embodiment shown, the frame 1 of the machine has a pair of links 2, 3 pivoted on it at 4, 5 and pivoted also to the carriage 11 so that the carriage, levers and frame form a quadric crank link system. This quadric system is swung to and fro by the eccentric 8 which is engaged by a follower 10 on the end of the link 3. The eccentric 8 is fixed to the driving shaft 9. As the carriage 11 is swung to and fro, the plates 12, 13, Figs. 6, 7, carried by it are also moved. These plates can be displaced in guide tracks 14, 14a, 14b, 14c, by the pins 15, 16 according to their engagement with the jacquard card 17. These plates have separate projections 12, 12a, 13, 13b, and recesses which co-operate with projections on the T-shaped levers 18, 19, Figs. 4, 5, pivoted at 20 on the frame. If the plates are moved by the jacquard card to cause either of their projections to engage the corresponding projection on the levers, the downward movement of the carriage causes the lever to be tilted as shown diagrammatically in Fig. 10, in which the lever 18 has been tilted to the right while the lever 19 remains unaffected. The lever 18 has at its upper end a pivot pin 21 which engages a recess 22a in the totalling member 22, Fig. 8. This member is rotatably mounted with its bore 23 on a pivot 24 of the lever 19. The position of the member 22 is thus dependent on the position of the pivots 21, 24 of the T-shaped levers 18, 19, as shown in Fig. 10. The member has a recess 60 for accommodating this pivot 20 during its assumption of its various positions. The form of the plates 18, 19 is selected so that one plate turns one lever in one direction and the other lever in the opposite directions, pairs of locking pawls 26, 27 for each plate being provided to prevent both plates moving together. When the carriage returns to normal position, the totalling member also returns to normal position. The return movement differs according to which position it had assumed, and the movement is transmitted to the connecting rod 36 and to a lever 37 carrying a toothed segment 39 engaging a pinion 40. The toothed segment is alternately coupled and uncoupled with the pinion 40 by a bell-crank lever 41 and eccentric 45 so that the pinion is moved by the totalling member. according to the setting of the plates by the jacquard card. The pinion is held during the disengaged period by a catch 47. The pinion 40 displaces the rack-bar which moves the embroidery frame to produce the pattern.
