Patent GB-933697-A (GB)
Title: Improvements in or relating to epoxides and their production
IPC: C08G59/02
Filed: 1961-05-26
Abstract: The invention comprises an epoxidized beta polymer of diallyl phthalate, preferably having an oxirone content of 0,6 to 3,6% by weight, which may be made by partially epoxidizing the diallyl phthalate beta polymer by reacting said polymer with hydrogen peroxide and a cyclic anhydride of a dicarboxylic acid wherein the oxygen-containing anhydride ring is a five membered ring containing four carbon atoms and one oxygen atom, such as phthalic or succinic anhydride, at temperatures above about 20 DEG C.  The epoxidized products are soluble in organic solvents such as benzene, toluene and xylene, from which they can be applied as liquid coatings by spraying, brushing or casting, in conjunction with a curing agent, for example, a peroxide, such as benzoyl peroxide, to form after drying and curing a tough adhesive coating.ALSO:Epoxy compounds are made by reacting an ethylenically unsaturated compound containing at least one unconjugated ethylenic group with hydrogen peroxide and a cyclic anhydride of a dicarboxylic acid wherein the oxygen-containing anhydride ring is a five-membered ring containing four carbon atoms and one oxygen atom, at temperatures above about 20 DEG C.  The cyclic anhydrides include those of saturated aromatic saturated aliphatic or cycloaliphatic dicarboxylic acids, preferably phthalic anhydride and succinic anhydride.  Suitable unsaturated compounds are unsaturated fatty hydrocarbons, fatty acids and esters, such as those present in naturally occurring oils, allyl esters of organic acids, cycloalkenes, dicyclopentadiene, aliphatic esters of D 4-tetrahydro-phthalic acid and styrene.  Preferably 30 to 70% aqueous hydrogen peroxide is used and the reaction is effected below 60 DEG C.  An inert organic liquid may be present if desired.

Abstract: 744,642. Dispensing measured quantities of liquid. BRITISH THOMSONHOUSTON CO., Ltd. July 15, 1953 [July 16, 1952], No. 19647/53. Class 106(5) [Also in Group XI] In apparatus for removing a metallic light-reflecting coating from the lower portion of an electric lamp bulb or similar hollow glass article the inner surface of which has been covered completely with such a coating in a previous operation, a measuredquantity of a solvent, e.g. an acid solution, is introduced automatically to the required cut-off level within the bulb and automatically removed therefrom after a predetermined time interval (see Group XI). The charge-measuring devices 145, Fig. 15, which measure accurately the individual charges of solvent for the respective bulbs, each comprise a vertical flask 184, preferably of glass, with a bottom outlet 144 connected to a tube 143 leading to a filling head which dips into the bulb, and an inlet 155 located about midway between the ends of the flask. The upper end is .closed by a rubber plug 185 with a central bore provided with an airtight bush 187. An enlarged head or collar 188 on the upper end of the bush 187 is bevelled inwardly to form a circular knife-edged seating 189 which co-operates with a rubber collar 195 fitting closely upon the stem 192 of a float 191 disposed within the flask. The position of the collar is adjustable to predetermine the measured quantity of solvent. A stop collar 193 on the part of the stem within the flask limits the outward projectiion of the stem and also tends to prevent it from jamming during the filling of the flask, an air lock being prevented during filling by providing the lower end of the bush 187 with serrations 194 which communicate with the bore 186 of the bush. The collar 195 acts as an atmospheric pressure valve by seating upon the annular knife edge 189 and sealing the tube, thus controlling the amount of solvent flowing out of the flask The inlet and outlet tubes of the flask are provided with control valves which are operated automatically.

A radiation screen 1 formed as a partition has an opening into which is fitted a hollow transfer component (for transferring material from one side of the screen to the other); the component itself has an opening giving access to its interior, and is movable so as to present its opening to the space at either one side or the other of the partition; the component, or at least the part surrounding its opening, is of radiation-absorbent material so that in all positions a complete radiation shield between the two sides of the partition is maintained. The partition separates a zone containing X-ray apparatus from a zone in which the films or plates are stored or processed. The transfer component is in the form of a hollow rotatable cylinder 8 having an opening 7, and an internal dividing wall. Fresh film is loaded into the cylinder from one side of the partition, and it is then rotated through 180 degrees and unloaded from the other side, the process being reversed with exposed film. Handles 9 are provided on each side for effecting the rotation, by manipulating first one handle and then the other. The cylinder 8 and the frame 6 of the partition opening are made of or faced with radiation-absorbing material, so that in all positions of the cylinder 8 there is a complete radiation shield between the two sides of the partition.
