Title: A Process for Making Reproductions by Means of Heat.
Inventor: SEIBERT HEINRICH
IPC: B41M5/035
Filed: 1967-04-04
Abstract: 1,172,762. Printing process. AGFAGEVAERT A.G. 4 April, 1967 [9 April, 1966], No. 15386/67. Heading B6C. A process for making reproductions comprises heating a copy sheet in close contact with a printing forme having an image layer containing a sublimable dye, the dye being transferred to the copy sheet; the printing forme comprises a supported image layer containing the dye dispersed in a binding agent which is a mixture of an acrylonitrile/styrene copolymer and a copolymer or graft polymer of butadiene, acrylonitrile and/or styrene. The binding agent preferably contains 10 to 35% by weight of acrylonitrile, 40-70% styrene and 10 to 35% butadiene, all in polymerized form, and the dye preferably sublimes at 140-180 C. The dyes exemplified are the same as those disclosed in Specification 951,987. The printing forme may be prepared by direct typing on to a support with a dye foil containing the dye in contact with the back face of the support, or by exposing an original, the support sheet and the dye foil, arranged in contact, to infra-red radiation, in which case pre-heating of the layers to 120 C. is preferable. Plasticizers may be used to loosen the cohesiveness of the dye layer, and other synthetic polymers, e.g. P.V.A., may be used to improve adhesion to the printing forme.

Patent GB-965692-A (GB)
Title: Preparation of uranium and thorium oxide sols
IPC: C01B33/20
Filed: 1961-04-28
Abstract: Urania or thoria sols are produced by heating an aqueous solution of a soluble salt of uranium or thorium in the presence of excess urea to effect complete hydrolysis to the oxide, the reaction being carried out under reflux at the boiling point in the case of thorium and at a temperature of at least 75 DEG  C. with agitation in the case of uranium.  The pH for thoria precipitation should preferably be from 2.5-3.5 and should not exceed 5 whilst for uranium the pH preferably is below 2. The electrolytes may be removed from the sol by passing it through a mixed anion-cation exchange resin bed or the sol may be allowed to flocculate, the floc separated and redispersion effected in de-ionized water. Flocculation can be induced by the addition of an ammonium salt. The sol obtained having particles from 50-200 microns, has a specific conductance of 10-6 to 10-2 mhos./cm. According to examples: (1) a solution of thorium nitrate was treated with incremental additions of aqueous urea and heated under reflux, the final pH being 5. The ammonium nitrate formed by the hydrolysis of the urea flocculated the sol and after settling the supernatant liquid was drawn off and replaced by de-ionized water.  The final sol has a thorium content of 4.2, a pH of 5.4 and a specific conductance of 2.5 x 10-5 mhos./cm. The sol particles were spherical and of 70-105 micron size, (3) a sol such as that of Example 1 was centrifuged, the supernatant liquid removed and replaced by de-ionized water and again centrifuged at 10,000 r.p.m. After repeating this procedure, the pH of the product was 3.5 and the specific conductance 5.4 x 10-4 mhos./cm. If desired, the sol resulting from centrifuging and replacement of the supernatant liquid by de-ionized water may be passed through a mixed cation-anion exchange resin bed (6). Uranous chloride solution containing excess hydrochloric acid and having a pH of 0.38 was reflexed in an atmosphere of nitrogen and urea added in one large first increment followed by spaced smaller increments until the pH rose to 1.  The resulting sol was treated in the manner indicated above. The thoria and urania sols so produced may be employed in nuclear reactors and to ensure stability at temperatures approaching 300 DEG  C. under heavy neutron flux, the thoria sols can be coated with silica by mixing a silica sol with the de-ionized thoria sol followed by the addition of sodium hydroxide to bring the pH to 10. The coated sol was refluxed for 24 hours at 100 DEG  C. and passed through a cation-exchange resin and the effluent adjusted to pH 8. Specification 965,693 is referred to.

Patent GB-165782-A (GB)
IPC: H04M7/06
Abstract: 165,782. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Martin, T. G.). June 30, 1920, [Convention date]. Automatic exchange systems.-When an exchange is started with a small number of subscribers, say several hundred, but with a numbering system designed for the ultimate inclusion of a much larger number, say 10000, one of the switching stages is temporarily omitted, the corresponding digit being suppressed by one of the selectors. For example, a given area may be designed to be served eventually by ten exchanges of 10000 lines each, all the subscribers being given 5- digit numbers. Whe one of the exchanges, corresponding say to the first digit 3, is started with several hundred subscribers, these subscribers are given numbers in the range 33000 to 33999, and all the first selectors in the area are arranged to release themselves after being set by the first digit 3 and then to set themselves again in response to the second digit 3, extending the call to the wanted exchange where the last three digits operate a second selector and connector. When the number of subscribers at the No. 3 exchange has grown to more than 1000, an additional selecting stage is introduced at the exchange, and the device for suppressing the first digit 3 is withdrawn from the first selectors. The circuits of a digit-absorbing first selector are shown in Fig. 2. When the selector is raised to to its third level, a cap 21 operates a group of springs 22, 24, 25, 26, 27, so that when relay 15 de-energizes, at the termination of the first series of impulses, circuits are closed (1) for the release magnet 19, (2) for a sluggish relay 14, which locks itself up and opens the circuit of the release magnet, so that the selector is not released after the second series of impulses. To cancel the digit suppressing function it is only necessary to remove the spring 22. The group of springs 22, 24, &c, may be mounted so as to be adjustable to different levels, and several such groups, angularly displaced with reference to the operating-cap 21, may be fixed at different levels, to control the suppression of the first digit in calls to several different embryo exchanges.
