IPC: G03G13/10
Filed: 1965-03-01
Abstract: 1,095,504. Electro-photographic development processes. RESEARCH LABORATORIES OF AUSTRALIA PTY. Ltd. March 1, 1965 [March 6, 1964], No.8736/65. Heading G2H. A charge image of negative polarity is reversal developed to provide stain-free areas, where most of the initial charge is retained, by contact with a developer consisting of a dispersion, in an insulating carrier liquid, of charge inhibited toner particles depositable only in the presence of a soluble mineral oil or grease as development inducing agent. The oil or grease contains specified quantities of anti-oxidant and detergent-dispersant. The developer is stated to give a clean cut-off where a predeterminable fraction of the initial charge is retained and a uniform deposition over all other less charged or uncharged areas. When used in preparing positive copies of printed matter from low-density negatives, in which the background (i.e. non-image areas) is not completely opaque, a stain-free background is thus obtained. Chargeable toner particles may be made charge inhibited by coating them with an oleoresinous polarity control agent which takes a charge of the opposite polarity and may be further coated so that they do not adsorb the development inducing agent. Alternatively, oppositely chargeable toner particles may be mixed to form charge inhibited aggregates which are treated with a dispersant which also prevents the particles from adsorbing the development inducing agent. According to one example, carbon black pigment is coated by milling with a hydrogenated rosin, as polarity control agent, and further coated with boiled linseed oil to prevent adsorption of the development inducing agent. This charge inhibited toner is then dispersed in one of the following carrier liquids: paraffinic, iso-paraffinic or aliphatic liquid, mineral spirit, cyclo-hexane, perchlorethylene, carbon tetrachloride or trichlorotrifluoroethane. The development inducing agent may be paraffin oil containing zinc alkyl dithiophosphate or a substituted para cresol as anti-oxidant and sodium alkyl benzene sulphonate or sodium naphtha sulphonate as detergentdispersant. In another example, phthalocyanine toner particles are coated with a pentaerithritol resin as polarity control agent and a wheel base grease containing additives is used as development inducing agent.

Title: Improvements in or relating to the manufacture of barbituric acid derivatives
Filed: 1934-03-23
Abstract: N-Mono- or di-alkylated barbituric acids substituted in the 5-position by a methyl group and a group X are prepared by known methods.  The group X comprises a saturated cycloalkyl group, or a saturated alkyl group which may be substituted by a cycloalkyl residue, or an unsaturated alkyl group or halogen derivative thereof, provided the group contains at least three carbon atoms. Methods involving the treatment of 1-cyano-2-imino-barbituric acids are, however, excluded.  The products possess therapeutic properties, and in the case of the N-monoalkyl compounds may be converted into their salts with inorganic and organic bases. According to the examples: (1) n-butyl-methyl-malonic acid diethyl ester is treated with methylurea to give N-methyl-C : C-methyl - n - butyl - barbituric acid; N - methyl-C : C-methyl-n-hexyl-barbituric acid may be similarly prepared; (2) N-methyl-C : C-methyl-allyl-barbituric acid is prepared from methyl-allyl-malonic acid diethyl ester and methyl-urea; N - methyl - C : C - bromallyl - methyl-barbituric acid is similarly prepared, whilst from allylurea and methyl-isoamyl-malonic acid diethyl ester, N-allyl-C : C-methyl-isoamyl-barbituric acid is obtained.  Specifications 1664/03, 14014/04, 11219/05, [all in Class 2], and 391,741 are referred to.  The Specification as open to inspection under Sect. 91 also describes the alkylation of cyanimino derivatives of barbituric acid and the saponification of the resulting N-alkyl compounds. It contains an example of the preparation of N-methyl-C : C-cyclohexyl-methyl-barbituric acid by reacting cyclohexyl-methyl-malonic acid diethylester with dicyandiamide, treating the product with dimethyl sulphate and then saponifying. N - Methyl - C : C, isopropyl-methyl- and N-methyl-C : C-b -ethylhexyl-methyl-barbituric acids are stated to be-prepared in the same way.  This subject-matter does not appear in the Specification as accepted.  Malonic acid esters.  Methyl-n-hexyl-malonic acid diethyl ester is obtained by reacting sodium n-hexyl-malonic acid diethyl ester with methyl iodide.  The Specification as open to inspection under Sect. 91 also describes the preparation of cyclohexyl-methyl-malonic acid diethyl ester by treating sodium malonic acid diethyl ester with cyclohexyl bromide and methylating with methyl iodide, and of b -ethylhexyl-methyl-malonic acid diethyl ester in the same way using b -ethylhexyl bromide.

Title: Improvements in or relating to extrusion presses
IPC: B29C48/32
Filed: 1955-03-30
Abstract: 805,366. Extrusion machines. KRAUSSMAFFEI A. G. March 30, 1955 [July 12, 1954], No. 9237/55. Class 87(2). [Also in Group II] The impelling screw 4 feeds material through a casing 12a and thence out through a shaping nozzle 15a. The casing 12a has semi circular-section grooves 13a extending along the interior surface thereof. Within the casing 12a and extending into the nozzle 15a is a rotating milling head l0a having similarlyshaped grooves Ila on the exterior thereof. Within these grooves the material, e.g. polyvinyl chloride, is mixed and kneaded and the heat thus generated may render the material sufficiently plastic to obviate the necessity for additional heating. The degree of such heating may be varied by increasing or decreasing the length of the milling head or by axially shifting it to vary the spacing between the head and casing 12a. As shown, the casing 12a and nozzle 15a both taper, and the head is integral with the screw shaft, the axial position of which may be adjusted by means of plates 22 and shims 25 or by a screw connection between a plate 22 and barrel 1, in which latter case the spacing between head and casing may be adjusted during operation of the machine. The machine shown produces solid rod of circularorpolygonal crosssection. In another form for producing tube, the casing, nozzle and head are all cylindrical, and the head projects through the outlet of the nozzle. The head portion 20a may have a diameter greater than that of the head proper 10a. In another form for coating wire, the casing and head are cylindrical and the nozzle tapered. In another form, the inner ends of the grooves are flared both vertically and horizontally, to receive large pieces of material ; the milling head either tapers or is cylindrical with a tapered end in the nozzle. In a modification only the grooves on the casing are flared and the head is threadedly connected to the screw shaft. The screw may extend horizontally or vertically or slantwise.

Emulsions or suspensions of fat and water or mixtures containing coagulizable components in suspension or solution are dried by a process comprising the steps of (a) first cooling the mixture at a temperature sufficiently low to cause at least part of the water in the mixture to freeze followed further cooling at the same or at a lower temperature (b) raising the temperature of the mixture to thaw the mixture (c) removing at least part of the water and (d) dehydrating the resultant residue. The freezing may be effected, after an initial pre-cooling, by cold storage or a blast of cold air. The thawing may be effected by warm air or steam or H.F. or radiation heating. The mixture may be covered by a polyethylene terephthalate film during freezing and thawing. After thawing the water may be removed by centrifuging, straining or filtering. The dehydration may be effected by freeze-drying or by absorption of water into a desiccant e.g. an alumino-silicate, under a reduced pressure. Preferably the mixture is "sandwiched" between desiccant layers, being separated therefrom by moisture-permeable barriers. The mixture, which may be real or imitation cream, milk or yoghurt, may be pasturized before, between or after the freezing steps, and the dehydrated product may be suitably disintegrated.
