Title: Improvements relating to the separation of liquids and solids
IPC: B04B3/00
Filed: 1920-11-08
Abstract: 176,446. Avrutik, J. Nov. 8, 1920. Density separators; discharging.-In a centrifugal machine for separating the liquid and solid content of substances, the incoming matter is fed in a continuous stream and is subjected to a succession of liquid-separating operations. The apparatus is particularly suitable for the separation of molasses from crystallized sugar. In the form shown, four baskets 5, 6, 7, 8 are superposed and driven from the shaft 13 by the motor 15. The top basket 5 is cylindrical and the others 6, 7, 8 are conical; the inclination of the sides to the vertical axis of each basket is greater than in the one above. Each basket has a plain base 9 and perforated side walls 10 provided with a fine wire gauze 17. Below each basket 5, 6, 7 is a liquidreceiving pan 19, and below the basket 8 is a pan 20 which receives liquid from the pans above it and has a discharge pipe 21. The central parts 22 of the pans have flanges which project into upwardly projecting flanges 23 from the pans beneath, and holes in the parts 22 enable liquid to pass through the series of pans. A rubber piece 25 on each flange 23 and a piece 27 on the rim of each pan 19 make liquid-tight joints between the pans and baskets. The casing has a series of annular grooves 35 and downwardly projecting flanges 36. The syrup or other material is introduced into the hopper 32 by a shoot 33 and passes into the basket 5, where it is thrown to the circumference. The finer liquid passes through the basket wall and is collected by the pan 19, from which it passes to the discharge pipe 21. The thicker liquid with the sugar crystals passes over the rim of the basket 5, down the flange 36, and into the basket 6. This action is repeated at each basket until the dry crystals are delivered into the discharge hopper 38. To prevent particles from adhering to the side walls, a perforated coil 40 is provided above each basket and is supplied with compressed air, water, or steam.

Abstract: 331,161. Tarnawski, F. Oct. 18, 1928, [Convention date]. Preserving gherkins, cucumbers, beetroot etc.; condiment preparations.-Gherkins, cucumbers, beetroot, and like fruits or vegetables are preserved by first allowing them to ferment in a strong, e.g. 10 per cent, salt solution, soaking them in water until tasteless, and then placing them in containers with spices or other additions with a sweetened vinegar solution, and finally sealing the containers and sterilizing by heating for a short time, e.g. 5-10 minutes. A layer having such ingredients as bay leaves, tarragon, horse-radish, capsicum pods, onions and carrots may first be added to the container. The gherkins are then placed on this layer with mustard and pepper grains scattered between them. Another layer of the additional ingredients is then added and the vinegar solution, which may be of 2 per cent strength with 50 gms. of sugar in each litre, is poured over the contents of the container which is then sealed and sterilized. The additional substances, such as carrots, which are fermentable are allowed to ferment separately before addition and others such as herbs are allowed to dry and are then placed in a solution of salt and vinegar before being added to the container.

Abstract: 955,987. Counters. SOLARI & C./UDINE S.p.A. Sept. 20,1960 [Sept. 21,1959; April 6, 1960], No. 32298/60. Heading G4D. Transfer mechanism comprises a freely oscillatable tooth 31 which is carried along by a lever 32 driven by the lower denomination wheel to engage between the teeth of the next higher denominational wheel to effect transfer, the freely oscillatable tooth being, however, readily displaceable when resetting is effected. The invention is applied to a petrol pump with amount and cost counters (Figs. 1-3 not shown). An electromagnetic pawl-and-ratchet or stepping motor (Fig 17, not shown) drives the lowest order in known manner. Indicators. The numeral wheels, Fig. 7, carry ten flaps P freely pivoted from appropriate points on flanges 17, 18, Fig. 12. A digit is indicated by two flaps in combination, the upper being held by a counter-weighted catch 22, the lower hanging freely. Transfer, Figs. 9, 10, 11, 14, 15. A lower denominational wheel 12 drives a wheel 28 on a separate shaft integral with a lever 32 the end of which is bent over. At transfer the lever 32 picks up a freely hanging tooth 31 to engage and advance the wheel of the next higher denomination. A ball 27, Fig. 11, normally holds the higher wheel against rotation but at transfer the ball is permitted to enter a recess in the lower denominational wheel against the action of a leaf spring 19, Figs. 14, 15. Resetting. The numeral wheels are mounted on a shaft 3, Fig. 6, having frusto-conical sections. Resetting is effected by an electric motor and cam (not shown) which first displaces the shaft 3 axially against spring action and then rotates the shaft through one revolution. The axial translation lifts spring tooth 15 of any wheel not showing zero. It also frees lever 23 carrying ball 27 between each pair of wheels, Fig. 10, to act as a brake during rotary movement. Resetting is effected by forward motion so that transfer tooth 31 is unaffected. As the shaft 3 rotates each spring tooth 15 falls into a groove 56 whereby the associated wheel is carried on to zero. The shaft 3 then returns axially to normal position under spring action. Modification, Fig. 24. To enable successive transfers without excessive strain the intermediate gear 103 driven by a lower wheel has a cam which stretches a spring 112 until digit 9 is reached. At the next step lever 110 falls off the high point, the spring giving a snap action to the gear 103 and transfer tooth. Specification 955,986 is referred to.
