Fig. 5 shows the arrangement when the plug, moving in the direction of the arrow, has reached the closed position, and has been arrested by the nose 26 of the stirrup, abutting against the inclined wall 32 on a fixed ring 17. On further rotation of the head 8, 9 the nose 26 tilts into a recess 29 and releases the pin 35 which thereupon moves under the part 21 of the stirrup, oppositely-disposed slots 33 through which the cross-pin 5 passes allowing for this lost-motion. This latter movement by reason of the screw engagement 10 between the head 8, 9 and the plug stem 4 causes the plug to be forced down tightly into its seating. In opening the cock, the reverse lost-motion eases the plug from its seating, rotation of the plug being meanwhile prevented by the engagement of the nose 26 in the recess 29 until the pin 35 reaches the notch 22' whereupon the stirrup drops to the position shown and the plug 2 and head 8, 9 move together to the open position.

Abstract: 856,585. Roller blinds. KESSLER, F. March 7, 1957, No. 7680/57. Class 20(3) [Also in Groups XXVI and XXXII] Mechanism for the withdrawal of a tape measure 116, Fig. 1, from its case, also stated to be applicable to roller blinds, cables and hoses, effects, through pinions and gearing, the tensioning of a spring 102 which, on release of the tape, ensures its automatic return. The tape is connected to an annular member 112 rotatably mounted in the case and carrying an annular gear 101 of forty teeth. A forty-one tooth gear wheel 103 carried by a member 114 is rotatably mounted within the case coaxial with the gear 103 and the helical spring 102 is connected between the members 114 and 112. A double pinion 104 is rotatably mounted between the case walls, the upper pinion part comprising fifteen teeth which mesh with the gear 101 whilst the lower pinion part comprises sixteen teeth which mesh with the gear 103. On withdrawal of the tape, twenty-four revolutions of the gear 101 causes the displacement of the gear 103 by nearly one further revolution thus tensioning the spring 102 by nearly one turn. In another embodiment, an annular member 15, Fig. 3, and a member 13 are rotatably mounted about a central shaft 8 and the spring-tensioning drive from the withdrawing tape 25 is transmitted from the gear teeth 19 of the member 15 to the gear teeth 18 of the member 13 through a single double pinion 20. Recesses 28, 27, in the members 15, 13, may accommodate devices for braking and arresting the withdrawing and returning tape. In a further embodiment, withdrawal of the tape 42, Fig. 5, causes an internally toothed annulus 43, which rotates with the tape spool core 41, and a meshing spring core pinion 37, which is mounted eccentrically in relation to the annulus 43, to rotate at different speeds. One revolution of the tape spool 40 will cause an angular advance of the pinion 37 by an amount depending on the difference in the number of teeth on the pinion 37 and the annulus 43, and owing to the connection of the spring 44 between the pinion 37 and the core 41 the spring will be tensioned accordingly. Fig 5 shows two tape breaking devices which are connected to tape arresting devices. Each braking device comprises a press-button 45 which is connected by a pin 46 to a brake disc 47. The button 45 is pressed outwardly by a compression spring 48 so that the disc 47 is held in the "off" position. Each device is operated by sliding the associated button 45 in a plane parallel to the housing wall 30, 31.

Title: Improvements in or relating to fractionation of a stock of cereal endosperm particles
IPC: A21D2/26
Filed: 1957-03-08
Abstract: In fractionating a stock of cereal endosperm particles, e.g wheat, barley, maize or rye flour from which the hull, bran and germ have been substantially removed, the particles are ground by impact, e.g. turbo-ground, to release a substantial proportion of the more cohesive whole starch granules and comminute the less cohesive protein matrix substances and are then air-separated at a selected critical cut, expressed in flow-dynamic (F-D) units, e.g. 20 units, as defined in Specification 815,597, to yield a coarse fraction having a starch content greater than the original stock and a fine fraction having a high content of protein and containing, for example, very small starch granules. Turbo-grinding may be effected by transporting the particles, in a stream of dry fluid, e.g. air, travelling at high velocity, through a chamber provided with spaced impact surfaces, e.g. blades on a rotor therein, so that the particles are moved in a multiplicity of curved circuitous paths, are made to impinge obliquely against the surfaces, and, for example, are made to spin to effect surface dressing of substantially all of the discrete starch granules.  The fluid may be fed into the chamber, at high pressure, through a plurality of jets.  The particles may be fed into the chamber in a direction substantially tangential to its walls.  When air is used, it may be heated to effect surface oxidation of the starch granules.  The stock may comprise a chunky fraction consisting of starch granules adhering to a protein matrix. This fraction may be isolated at a critical cut of the order of 71 F-D units and blended with the aforesaid fine fraction to produce a flour having a higher protein content then the original stock. Fractions and blends prepared according to the invention may be used in the making of bread and baked products of the batter-dough type such as angel cakes and griddle cakes.
