Patent GB-282327-A (GB)
Title: Improvements in or relating to mechanism for effecting vibration particularly applicable to screening and separating apparatus
IPC: B07B1/42
Filed: 1927-02-15
Abstract: 282,327. James, U. S. Dec. 14, 1926, [Convention date]. Reciprocating or oscillating sieves. -In apparatus for producing vibrations, an impacting rotary member transmits impulses in the form of a series of blows to a reciprocating plunger, the rotary member being a face cam with a succession of high points. The axis of the cam describes a cone in rotating. The invention is described as applied to a screening device. A frame 4 carrying the vibrating screen 5 is attached by flexible hangers 6 to a transverse bar 7 which is attached by a clamp 49 to a rod 50, which reciprocates in a plate 60 and in a plate 51 attached to the fixed casing 16. The plate 60 is adjustable by bolts 62 relatively to the fixed casing. and between this plate and a flange 58 on a rod 50 is a spring 59 for returning this rod to the right. At the end of the rod is an anvil 54 which contacts with the end 65 of a thrust member 63, Figs. 3 and 11; at the other end of this thrust member is a curved bearing piece 81, which is seated in a recess 80, Fig. 12, of a block 71 carried in a frame 64 hinged on a fixed pivot 67. A screw-threaded rod 75 having thrust collars 76 and a nut 77 is adapted to move the block 71 vertically in the frame 64 so as to bring the end 81 nearer the pivot 67. A hollow plunger 20 has a cross-piece 82 bearing against the frame 64. The line of reciprocation of this part 82 is unvaried, but by adjusting the block 71 the length of stroke of rod 63, and, therefore, of the reciprocating sieve, may be varied. The hollow plunger 20 is reciprocated against its spring 23 by its annular end face 26 coacting with projections 28 on an impact member, or face cam, 27, which is attached to a member 29 seated in a hemispherical bearing 31 lined with Babbit's metal. The shaft 30 of the impact member does not, substantially, rotate on itself, but describes, as a whole, a cone by reason of a member 39 at its end being loosely seated in a bearing near the periphery of a gear wheel 41. Thus, as the impact member is rolled by the shaft 30, its lugs 28 give a succession of blows to the plunger 20, and thence through parts 82, 71, 81 to the rods 63, 50 and to the sieve. The gear 41 is driven by an electric motor 43; in a modification it is driven through a pulley and belt.

Title: Improvements in self-closing valves for controlling the flow of fluids
IPC: F16K31/383
Filed: 1942-04-07
Abstract: 554,482. Valves. HOPKINSONS, Ltd., and DALE, W. B. April 7, 1942, No. 4549. Addition to 549,279. [Class 135] A self-closing valve of the kind claimed in the parent Specification is modified to prevent automatic reopening by pressure built up in the outlet conduit by leakage past the closed main valve. The main valve a which is opened by inlet pressure acting on the valve member when the pressures on the two sides of a leaky piston b are equalized. A passage d connecting the chamber c above the piston to atmosphere is controlled by a valve e normally held closed against the action of a spring i by pressure in the chamber g acting on a diaphragm f. The chambers g and c are connected by a passage h in the valve e so that the pressure in the chamber g follows that in the main inlet and when below a predetermined value permits the valve e to open and initiate the closing of the main valve. To re-open the main valve a quadrant j is moved by hand to hold the valve to its seat until a sufficient pressure has built up in the chamber g. The handle k may move the quadrant into contact with a stop m in which position the chamber g is connected to atmosphere through a vent n so causing the valve e to open and the main valve close.

Abstract: 526,474. Preserving and preparing potatoes; mashing and peeling. POTATO CORPORATION OF IDAHO. Feb. 14, 1939, No. 4877. Convention date, Feb. 15, 1938. Drawings to Specification. [Classes 28 (ii) and 49] After removal of the skins, potatoes are cut into slices, preferably about three-eighths of an inch thick, placed in water at room temperature and brought gradually to the boil. When the pieces are cooked they are separated quickly from the water and allowed to cool, and are then formed into small strips which are dried at a temperature, sufficiently low to avoid surface hardening of the strips and damage to the starch cells by swelling to the bursting point. The potatoes are placed in a basket and are skinned by dipping them in a lye solution, the skins and the solution being removed by cold water sprays. The potatoes, after slicing, are placed in a basket which is placed in a vat containing cold water rendered slightly alkaline by milk of lime or sodium carbonate, and steam is injected into the water to bring it to the boil in about 10 minutes. Cooking is continued for about 14 minutes, the water then being drained from the vat. The potatoes are allowed to stand for about 1 minute to equalize the moisture content and to ensure that the potatoes are cooked uniformly throughout. They are then dumped upon a perforated conveyer on which they cool, some evaporation taking place during the cooling. The potatoes are, or may be, cut into smaller pieces at the discharge end of the conveyer by spaced knives, and are delivered into a perforated horizontal drum having an internal roller which forces the potatoes through the perforations in the form of thin strings or strips which fall on to a conveyer passing through a drying-chamber. A counter-current of air at a temperature of about 70‹C., dries the strings which are removed from the conveyer by a rotary brush. The product is easily made into a mashed potato mass, by mixing with. an equal quantity of boiling water or milk and cooking for about five minutes. Specification 526,292, [Group V], is referred to.
