Patent GB-363713-A (GB)
Title: Improvements in and relating to the manufacture of sponge cakes and the like
IPC: A21B5/02
Filed: 1930-09-20
Abstract: 363,713. Making sponge cakes &c. BAKER PERKINS, Ltd., TARONI, C. E., Willesden Works, Hythe Road, Willesden, and ELLIS, E. G., 32, Poppleton Road, Leytonstone, both in London. Sept. 20, 1930, No. 28182. [Class 28 (i).] In the manufacture of sponge cake or the like, the sponge material is deposited in a continuous layer directly upon a continuous travelling oven sole. The oven sole may be a steel band or an assemblage of plates which form a continuous surface in the straight run of the conveyer. As shown, the conveyer 11 passes over tables 14, 15 before entering the oven 10. The table 14 supports a rotary brush and a rotary felt-covered roll for cleaning the conveyer 11. A scraper may be used instead of, or in addition to, the rotary brush. The table 15, as shown in Fig. 3, supports means for greasing and powdering the conveyer and for depositing the layer of sponge material. The grease is contained in a hopper 22 having a brush 21 arranged adjacent to the outlet or outlets, each of which is controlled by a stationary valve or plunger 27. The hopper and brush are reciprocated vertically by an eccentric 23 and connecting- rod 24 so that the reciprocations cause the delivery of grease past the plunger 27 to the brush which is constantly being contacted with the conveyer 11. The grease is spread by a brush 28 extending across the conveyer and receiving a rotary or orbital motion from cranks 29. The flour is contained in a hopper 31 having a felt covered roll 32 in the outlet. The feed is regulable by a slide 33 and the flour is brushed from the roll 32 on to the conveyer 11 by a rotary brush 34 partially surrounded by a shield 35. The axes of the roll 32 and brush 34 may be relatively adjusted. The depositing device 36 is of any known kind and is driven by a motor 37 through a variable speed gear 38. At the delivery end of the conveyer 11 a wire 13a strips the sponge cake from the conveyer 11 and it drops in the reversed position on a shoot 46 which leads it to a conveyer 48 on which it receives further treatment, e.g. cutting into lengths, receiving filling material such as jam or cream, coiling into roll form, or arranging in sandwich form. Preferably a jam or like depositor and spreader is positioned at the bottom of the shoot 46. Instead of leading the sponge downwardly over a shoot 46, it may be carried upward and reversed, or it may pass forward in a straight line and be cut and reversed by hand. Specification 276,061, [Class 28 (i), Bread-making &c.], is referred to.

Title: Manufacture of polymerised vinyl esters
IPC: C08F18/08
Filed: 1926-11-13
Abstract: 261,406. Consortium fiir Elektrochemische Industrie Ges. Nov. 14, 1925, [Convention date]. Polymerized vinyl esters.-The polymerization of vinyl esters, particularly vinyl acetate, is carried out in two or more stages, in presence or absence of a catalyst, whereby the difficulties arising from the violence of the reaction are avoided. For example, a small portion of the total amount of ester to be treated may be heated under reflux to initiate the polymerization, whereafter a further quantity of cold reaction mixture is run into the reaction vessel, while at the same time part of the reaction mixture is withdrawn from the vessel, the polymerization of the withdrawn portion being completed in a separate vessel. The heat of the reaction, besides being used, as described, to heat further amounts of the reaction mixture, may be used also to expel from the reaction products any unchanged vinyl ester which may be returned to the process. The process may be conducted in the presence of other liquids or of gases. Such liquids may be solvents, such as alcohol, or promotors of the reaction, such as acetic acid, or liquids which modify the properties of the products, such as an acetal. The gases may be indifferent gases, such as nitrogen or carbon dioxide, serving to exclude air or to enable the process to be conducted under pressure, or they may be gases, such as oxygen, which promote the reaction or modify the properties of the products. The polymerization may be carried out in more than two stages and may be interrupted at any stage to give products of different degrees of viscosity. The different stages may be conducted under different conditions, for example. heat being applied at one or more of the stages, and the process may be carried out continuously. Examples describe the polymerization of vinyl acetate admixed with one per cent of benzoyl peroxide, and of vinyl acetate (89 per cent) admixed with acetic acid (10 per cent) and equal parts of acetaldehyde, paraldehyde and potassium acetate. The Specification as open to inspection under Sect. 91 (3) (a) refers to the polymerization of vinyl compounds. This subject-matter does not appear in the Specification as accepted.

IPC: G05D13/08
Filed: 1929-08-20
Abstract: 344,398. Brakes. FREUND, B., 30, M³nchenerstrasse, Sch÷neberg, Berlin. Aug. 20, 1929, No. 28781/30. Convention date, Aug. 20, 1928. Divided on 317,735, [Class 40 (ii), Phonographs &c.]. [Class 103 (i).] Applied by speed-responsive devices.-Relates to hand-operated driving-mechanism for driving a sound or picture film, in recording apparatus, at a uniform speed, particularly for use in connection with the apparatus described in Specification 317,735. According to the invention, the driving mechanism comprises a spring through which the drive from a hand crank, rotated continuously or substantially so, is transmitted under the control of a governor to the film, so that irregularities in the rotation of the crank do not affect the movement of the film. Means may also be provided, whereby variations in the tension of the spring are automatically compensated for by action upon the governor. In the construction shown in Fig. 1, a hand-crank 140 drives a sound-record film 149 through a spring 141 and a train of gearing 143 .. 148. A centrifugal governor 147, driven from a wheel 146 of the transmission train, controls the speed. The governor includes a brake surface 160, the position of which relatively to the centrifugal weights is automatically varied by a tongs device 152, 158, which is so controlled by the spring 141 that as the spring expands the member 160 rises. Fig. 3 shows another arrangement wherein a handdriven spindle 200 winds up a spring in a drum 201, which, as it rotates, drives the film through gears 202, a shaft 204, and wheels 148, a governor 147 being arranged as shown to control the speed of the shaft 204. Epicyclic gearing 199, 210, 208 is so connected with the spindle 200 and the spring drum 201 that an arm 211 carrying the wheel 210 rotates around the axis 209 if the speed of rotation of the hand crank 30 and of the spring drum are unequal. By means of a member 212 mounted on the arm 211 and controlling the position of the part 160 of the governor, the action of the governor is automatically varied in accordance with changes in the tension of the spring as the wheel 210 moves in either direction around the axis 209. A pointer 213 moves over a scale 214, and may be adapted to operate bells or other signals to indicate when the maximum permissible change in tension of the spring has been reached in either direction. In a further construction (Fig. 2, not shown) a screw and nut device is used instead of and to serve the same purpose as the epicyclic gear shown in Fig. 3.
