Title: Improvements in or relating to wet protein preparations
IPC: D01F4/00
Filed: 1947-09-11
Abstract: Improved wet preparations, such as slurries, pastes, creams and suspensions, of certain purified proteins, are obtained by the addition of an aqueous solution of an alkali metal sulphite or bisulphite.  The proteins, which may be peanut globulin, soybean globulin, hempseed globulin or casein, are of a kind which are soluble in dilute acids and alkalis, except within the range of their isoelectric point (pH 4 to pH 6), are soluble in aqueous solutions of alkali metal sulphites and substantially insoluble in water.  The amount of alkali metal sulphite or bisulphite added is such that the resulting aqueous medium is not less than N/25 and has a pH value substantially equal to the isoelectric point of the protein.  If the pH value of the solution of sulphite or bisulphite needs adjusting, this is done by the addition of sulphur dioxide.  The product may be used for spinning even after long storage, damage from bacteria being prevented by the sulphite.

Title: Improvements in elastic guiding devices
Inventor: THIRY LEON
IPC: B62B7/10
Filed: 1931-09-07
Abstract: 388,095. Laminated springs. THIRY, L., 19, Rue Vankeerberghen, Huy, Belgium. Sept. 7, 1931, No. 25048. Convention date, Sept. 24, 1930. [Class 108 (iii).] A guiding device for connecting a leaf spring A to the frame B of an automobile comprises a ring C of elastic material compressed between an outer hollow member B and an inner member and adapted to roll with respect to them. As shown in the Figure, a sleeve F is attached to the end of the leaf spring A, and the outer member B, which may be split, is attached to the vehicle frame. This arrangement may be reversed, the inner member being on the frame. The spring may be supported at its other end in a plain or rubber-bushed fixed pivot or in a similar elastic guide. The rubber ring C may be initially round or polygonal or may conform to the shape of the rolling space, which may be circular, oval, polygonal, or square with rounded corners, and it may be thicker at its lower part or on the side of greatest load. Metal or moulded rubber stops N on either or both parts limit rolling movement of the ring. Rubber stops may be placed at each end of the rolling space to act as dust-seals. The rubber rings c may be split and more than one ring may be used, the outer rings forming stops. The rolling space may narrow from the centre towards both ends, making stops unnecessary. The space may be flared at N to facilitate inserting the ring. In a simpler spring shackle, the inner sleeve F is omitted, the two top spring-leaves engaging the rubber ring directly. The rubber ring C absorbs small spring movements without rolling and also permits torsional movement of the leaf spring.

Abstract: 759,579. Lubricating systems. BOSCH GES., R. Sept. 1, 1954 [Sept. 5, 1953], No. 25342/54. Class 12 (3). A housing 2 connected by a pipe 1 to a main lubricant supply line and by a pipe 1<SP>1</SP> to other distributers, is formed with cylinder bores 7 accommodating pistons 8. The pistons are spring-pressed and have stop members 9 of different lengths so that the strokes of the pistons vary accordingly. The cylinder bores communicate with a bore 6 containing a slide valve 17 which is formed on the outside with channels 20 and also has an axial bore 18 with transverse bores 19. The valve is pressed against a stop member 29 by a spring 22 fitted in a hole 21, which communicates by an opening 26 with a channel 20. The cylinder bores 7 at their outer ends lead to storage chambers 14 which are fitted with nipples 12 communicating with lubricating points. The storage chambers communicate with inclined bores 15 leading to the bore 6 of the slide valve 17. Lubricant intermittently fed, for example, by a piston pump, is forced through pipe 1 and moves the slide valve 17 to the left. Lubricant also enters the axial bore 18 and transverse bores 19 and eventually the pistons 8 are moved outwardly causing lubricant to be forced out of the storage chambers 14 to the points to be lubricated. When the piston pump ceases its stroke, the slide valve is pressed back to normal position by the spring 22 and lubricant is forced by the return action of the pistons 8 through the channels 20 and inclined bores 15 to the storage chambers 14. In a modification the bores 5, 51 are closed, the screw 28 is removed and connection is made to a hand operated or mechanically operated piston pump withdrawing lubricant from a reservoir.
