Title: A process for polymerizing together a plurality of polymerizable substances in the emulsified state
IPC: C08F293/00
Filed: 1946-03-04
Abstract: In copolymerizing in aqueous emulsion substances that by themselves cannot be polymerized or only with difficulty and substances which readily polymerize in that form, the latter substances are first subjected to polymerizing conditions and subsequently, after the induction period has elapsed almost entirely or for the greater part, the former substances are added. Readily polymerizable substances specified are vinylidene halides such as the chloride, vinyl halides and acetate, and acrylic and methacrylic esters and compounds. Specified compounds of the other class are isobutylene, ethene, vinyl ethers, maleic anhydride and fumaric acid esters.  In the example, sodium cetyl sulphate and hydrogen peroxide are used in the emulsion.

Title: Improvements in or relating to rotary coolers
Inventor: ERISMAN MAURICE JOHN
IPC: F26B11/02
Filed: 1958-03-03
Abstract: 825,814. Cooling granular, pulverulent, fibrous, and like materials. LINK-BELT CO. March 3, 1958, No. 6764/58. Class 64(2) In a rotating drum cooler, the depth of the bed of material to be cooled is determined by ring dams 33 and the bed is supported on an inner shell of louvres 47 between which cooling air passes from longitudinal passages 26 formed by radial plates 25 extending along the inner surface of an outer shell 15 of the drum. The material is fed in centrally of an end plate 28, Fig. 4, by a shoot 94, Fig. 1, and since the louvres 47 diverge towards the discharge end of the drum (the radial plates 25 being tapered), the material passes through the drum down the sloping length of the louvres and out at the other end. A stationary hollow ring 51 for the inlet and outlet of air to and from the rotating drum is sealed to the edge of the feed end of the drum by an assembly 57 and is divided radially by plates 58 corresponding to the plates 25. As shown in Fig. 4, between an outward extension 34 of the first ring dam and the feed-end end-plate 28, plates 48 extend along the air passages 26 to divide them into inner and outer sections 49, 50. There are corresponding plates 65 dividing the inlet ring 51 over the arc of the air inlet 84 to the ring, which arc corresponds to the arc covered by the material bed when it has ridden up the inner shell of louvres 47 upon rotation. By means of pairs of plates which be slid in arcuate paths in the ring 51 (one pair 78 corresponding to the inner sections 49 of the air passages and the other pair 79 to the outer sections 50) there can be adjusted, the position of the arcuate inlet aperture to each of these sections, where they lie adjacent the bed, and the size of these apertures, up to the full extent of the arc of the inlet 84. The cooling air which enters the inner sections 49 passes between the edges of the louvres 47 and through the hottest part of the bed at the feed end side of the first ring dam 33 and passes across the inner shell to the inner sections 49 opposite which are covered by an arcuately extending outlet portion of the ring 51. This outlet portion is divided by plates (similar to the plates 65 at the inlet 84 to the ring) and, further, the outlet 86 from this portion has two separate outlet openings 87, 88, Fig. 1. The hotter air from the inner sections 49 passes out through the opening 87 while the opening 88 is used to pass out the air which has passed through the outer sections 50 and the cooler, far end of the bed. The heat of the spent air is conveyed to combustion. air for other apparatus. Between the air inlet 84 and the air outlet 86, the stationary hollow ring 51 is closed by back plates 61 and by cover plates 64 which are removed when the aperture plates 78, 79 are adjusted.

The mould is surrounded by a glass, aluminium-oxide or siliconcarbide easing 8 connected to a negative pressure source 7. The casing 8 may also be connected to a source of inert gas. The material may be supplied in solid form or in liquid form intermittently or continuously. The moulds 15, which are pressed together by atmospheric pressure, are fed through a tube 10. Water-cooled rubber sealing rings are provided between interfitting parts. The moulds may be made as described in Specification 748,643. Vacuum bells may be provided over both ends of the tube 10. Continuous strips of material or tubes may be cast by employing a core such as 30, Figs. 3 and 4, the strips being subsequently rolled, if desired.

Abstract: 579,514. Portable stills. SAFETY-FUEL, Inc. April 14, 1944, No. 6930. Convention date, April 7, 1943. [Class 32] In a portable still, suitable for use at sea, having a boiling vessel and a stove for burning solidified normally liquid fuel, radially disposed metallic fins are attached to the undersurface of the vessel and metallic members extend transversely from at least a part of the fins, these metallic members being spaced apart from the side wall of the vessel: this arrangement directs the combustion gases from the stove into close contact with the side wall. In Fig. 1, the boiling vessel 51 is supported in an insulated casing 58 which in turn is supported by the shell 21 surrounding the stove 1. The undersurface of the boiling vessel is provided with metallic fins 72, 73, radially disposed and each carrying a transverse metallic member 77 (see also Fig. 2). Steam, generated in the boiling vessel, passes through the outlet 64 and flexible hose 65 which may be of sufficient length that part of it can be immersed in the sea in order to condense the steam, or alternatively, the end of the hose may be attached to a vented canteen immersed in the sea and thus serving both as condenser and receiver for the condensed water.
