Abstract: 1,207,162. Purifying solid peroxides. ARGUS CHEMICAL CORP. 23 Oct., 1967, No. 48102/67. Heading C2C. Solid fatty acid peroxides having at least 20 carbon atoms are separated from water and other impurities by adjusting the temperature of the mixture to above the melting point of the peroxide but below its decomposition point, separating the aqueous phase with impurities from the liquid peroxide phase while maintaining the liquid phase above its melting point, and then cooling the dry, purified peroxide phase. Temperatures about 2 to 3 degrees above the melting point are generally preferred. Separation may be carried out by conventional means. The process is preferably carried out using an alkaline impure mixture.

Abstract: 1,139,534. Hydrodynamic brakes. CATERPILLAR TRACTOR CO. 31 Oct., 1966 [22 Nov., 1965], No. 48691/66. Heading F2E. In a hydrodynamic brake for an earth moving vehicle a rotor 16 carrying impeller blades 16e is formed with a web 16b which includes a curved portion 16c having spaced apertures 16d, and the rotor is arranged within a two-part housing 17 providing working stator pockets 17d, the housing provides an inlet passage 26b of constant cross-sectional area between an arcuate part 26c and a fluid inlet comprising a cylindrical tube 27 of circular cross-section, the crosssectional shape of the passage 26b changing gradually from circular to arcuate oval form in the direction of fluid flow. The port 26c for fluid communicates via radially outwardly tapered passages 26d on either side of the rotor web with the stator pockets, the arrangement being such that fluid is able to move in smooth curves from the port 26c to the passages 26d and that the cross-sectional area of the passages 26d is substantially constant between their radially inner and outer ends, whereby fluid turbulence, cavitation, and noise are alleviated. An outlet passage 26f leads from a rectangular annular space 26e surrounding the rotor, the cross-sectional area of the space 26e increasing in the direction of rotation until reaching a point where the passage 26f branches off (Fig. 2, not shown). The cross-sectional area of the passage 26f also increases in the direction of fluid flow and its shape changes gradually from rectangular through oval to circular section where the passage 26f leads into a hoseconnection (26h, Figs. 2 and 3, not shown). The brake is arranged to be driven by a drive shaft 10 of the vehicle via a flywheel 11 and a gear 12 which is conveniently secured to rotor shaft 12 by a splined connection, a bolt 14 and awasher 15. The shaft 12 is supported by bearings 18 and 19 and carries the rotor hub 16a on its splines midway between bearing 18 and the gear 12.

The head plate and pressure fingers are displaceable on the shaft relative to the flange plate by a limited amount against the force of a plurality of spring devices 16, in order to accommodate different container heights. A rigid external shell 20 is connected to the flange plate and forms an opening 21 underneath the free ends of the pressure fingers, the diameter and height of the opening matching the dimensions of a permanently deformable cover 25. The external shell is composed of annular elements 22 and 23, detachably connected to one another and the flange plate by screws 24 and 27 so that the element 22 can be changed to vary the distance H and thus accommodate different cover heights. The opening has a bevelled edge 28 to aid introduction during centring of the cover on the container and the pressure fingers deform and secure the cover on the preferably screw-threaded neck of the container. In an alternative embodiment (Fig. 2a) the external shell is constructed with an inwardly projecting flange 133 and the pressure fingers have extensions 131 held in the circular groove 132 of flange 133 to restrict radial inward movement of the fingers. The steel sleeve 15 is a strip whose ends can be drawn together by clamping screws thus restricting the radial outward movement of the fingers.
