Abstract: 177,761. Soc. Ricard, Allenet, et Cie. March 26, 1921, [Convention date]. Addition to 173,735. Treating-materials; manures.-The process for clarifying saccharine juices by adding a soluble alginate and precipitating an insoluble alginate described in the parent Specification is applied to liquids of different classes. As examples are described the treatment of tannin extract, barium formate being used as the precipitant; and of the waste water from starch factories with an alginate and lime. The precipitate obtained in the first case is used as manure. When the liquid treated contains a substance which will precipitae the alginate. as in the case of brandy contaminated by contact with iron, the addition of further precipitant may be unnecessary, but it may be added if the alginate is in excess. In this case also the precipitate is serviceable as manure.

Abstract: 640,049. Dish-washing machines. OWEN, J. Dec. 5, 1947, No. 32128. [Class 138(i)] A crockery washer comprises an outer casing in which is removably mounted an inner perforated or openwork container that is adapted to be rotated, or oscillated in the outer casing, the bottom of which is formed with a central aperture adapted to be closed and opened by lowering and raising the inner container. An outer casing A, Fig. 5, is mounted on feet L and has a conical-shaped opening D situated centrally in its bottom. A container B, Fig. 4, having a centrally positioned conical projection F in its bottom, to the lower end of which projection is fixed a rubber washer E, is mounted in the casing A so that the washer E is seated in the opening D. The container B is also provided with apertures M in its bottom. The upper end of the casing A, Fig. 2, has an inwardly turned rim J which engages with the upper perforated surface of the container B. The perforations may be of different shapes and sizes. Crockery is placed in the container B, hot water poured thereon, and a lid is placed on the container. The container is then rotated by handles K to agitate the water and clean the crockery. Water is drained from the casing by raising the container to unseat the washer E. The container may be in the form of a wire basket and the opening F may be replaced by a tap. The outer casing may be connected directly to a hot water supply pipe. The inner container may be provided with a plate rack. In another embodiment a coiled pipe may be provided to extend around the inner container but not making contact therewith. The pipe may have inwardly directed apertures and may be attached by a flexible pipe to a hot water or steam supply. The Provisional Specification states that the projection on the bottom of the container B may be fitted with a removable bush or bearing which can be replaced when worn.

Title: Improvements in or relating to apparatus for dispensing towelling, paper or equivalent material
IPC: A47K10/36
Filed: 1936-11-25
Abstract: 491,308. Towel cabinets. STEINER SALES CO. Nov. 25, 1936, No. 32262. Convention date, July 20. [Class 18] Towelling from a roll 2, Fig. 2, in a cabinet can be drawn out until arrested by stop mechanism which is released after a definite timing period which follows the tearing off of the protruding portion of towelling against a spring- pressed, pivoted knife 40. The towelling passes over a roller 20 which carries a pivoted catch 57 and a link 52, the latter having a pin-and-slot connection with the roller at one end and a pivoted connection with a lever 48 at the other. As the roller rotates, the link raises the lever 48 until a shoulder 47 on a cam surface on the roller abuts against a shoulder 50 on the lever 48 and stops the roller. During this movement, the lever 48 has also raised an angle member 60 and the catch 57 has moved round until, at the moment of arrest, the catch engages under the horizontal lip of member 60 and prevents the stop mechanism from disengaging. The catch 57 is connected to the pivoted knife by a link 62 so that, as the former is moved during the tearing off of the protruding piece of towelling, the catch is released, the member 60 drops ever so slightly, and the timing period commences. The member 60 carries a vacuum cup 78 which, when the member is raised, engages a fixed vacuum cup 80, the latter having an air intake and an adjustable valve 87 whereby the apparatus is not released after the catch 57 is withdrawn until after a certain interval has elapsed. Instead of two vacuum cups, one cup operating against a plate may be used. The spindle of roller 20 carries an arm 70 of which the free end is connected by a spring 72 to a fixed part of the cabinet and, at the moment when the stop mechanism comes into operation, the spring is under tension. When the stop mechanism releases, the spring pulls down arm 72 to give a slight rotation to roller 20 and thereby feed out a small piece of towelling which can be grasped to pull out more. The end of the timing period is indicated by a bell 95 which is actuated by the member 60 as it drops. A spring-pressed roller 27 keeps the towelling in contact with the roller 20, and the latter may be rotated by a crank as well as by a pull on the protruding piece of towelling. For emergency purposes a small portion of towelling can be protruded by depressing a lever 101, Fig. 7, the latter being formed with teeth which, on the downward stroke, engage the teeth on a ratchet wheel 100 on the spindle of roller 20. The pivoted knife may be replaced by a fixed knife. Specification 491,372 is referred to.

Abstract: 504,949. Speed governors. LOGAN, H. H. Nov. 23, 1937, No. 32282. Convention date, Dec. 2, 1936. [Class 57] [Also in Group XXX] A speed-controlling device for mine hoists, elevators, bridges, &c. comprises two centrifugal governors A, B each of which is geared to a shaft 210 driven by bevel wheels 212, 211 and a pinion 205 from the moving mechanism which is to be regulated. The gear wheel 222 of the governor B is larger than the wheel 221 of the governor A, so that the latter rotates faster than B. The governor B has a cornpression spring 237 against which the outwardlyflying balls 231. act to press down a ball-bearing head 238, and by way of a pivoted two-armed lever 242, 245 and links 255 to raise a yoke 249 pivoted to the frame 203. The governor A is similarly connected to the yoke 249 so that a differential or composite movement is imparted thereto and conveyed to a power or overspeed switch, or to a brake &c. by a perforated lug 254. The spindle 244 of the lever 242, 245 has an arm extending from it on which bears the end of an adjustable spring which in effect alters the strength of the spring 237 of the governor B, thus allowing of adjustment of the relative lifts of the two governors on the yoke 249.
