Title: Improvements in or relating to the production of alkyl silicones
IPC: C08G77/00
Filed: 1946-09-13
Abstract: In a process for the production of thermosetting methyl and ethyl silicones which are stable on storage at normal temperatures by heating at a temperature of at least 75 DEG  C. and in the absence of a metal salt, the silicone dissolved in an organic liquid, the liquid and water are continuously distilled off.  Preferably, the solvent forms an azeotropic mixture with the water and suitable solvents specified are benzene, butyl acetate and diethyl ether. In examples, the hydrolysis products of ethyl magnesium bromides and silicon tetrachloride are heated in benzene under distillation conditions, the benzene after separation of water in the distillate being returned to the still.ALSO:Thermosetting methyl and ethyl silicones which are stable on storage at normal temperature and are suitable for heat-resistant paints, varnishes or water-proof coatings, or as cement for electric bulb caps, are prepared by heating in the absence of any metallic salt a methyl or ethyl silicone at a temperature of at least 75 DEG  C. in an organic liquid medium which is a solvent for the silicone, and thereafter distilling off the organic liquid and any water present.  Suitable solvents are benzene, diethyl ether and butyl acetate, and the treatment may be conducted under pressure. In examples: (1) ethyl silicon chloride in ethereal solution is hydrolysed and the solution after neutralization is concentrated, benzene is added, and the ether is distilled off. The benzene solution is refluxed and water separated from the azeotrope distilling off is continuously removed in amount 5 per cent of the weight of resin, and the benzene is then distilled off.  The product which is soluble in alcohol and benzene, hardens on heating to 225 DEG  C.  (2) The procedure of example (1) is followed using methylin place of ethyl-silicon chloride.  The solid product becomes insoluble on heating to 200 DEG  C.

Title: Improvements in and relating to anaesthetic and analgesic administering apparatus
IPC: A61M16/10
Filed: 1950-11-14
Abstract: 695,576. Anµsthetic appliances. SPENCER, T. H. N. Feb. 13, 1952 [Nov. 14, 1950], No. 27735/50. Class 81 (ii). [Also in Group XXVIII] In gas administering apparatus using carbon dioxide cylinders which are smaller than nitrous oxide cylinders, a detector device is fitted to the cylinder carrier, which gives a warning if gas from the wrong cylinder is used. When a nitrous oxide cylinder 26 is fitted in the carrier frame 31, gas flows through an attachment fitting 5 to a reducing valve 7 and thence to the inlet 10 of the warning device. At the same time the lower end of the cylinder bears against a stirrup 32 and presses a rod 29 inwards so as to turn the spindle 17 clockwise. This results in closing a valve leading to a whistle, opposite inlet 10, and opening a valve leading to outlet 12 and pipe 25. If a carbon dioxide cylinder 36 is wrongly connected in this position, its length is insufficient to allow it to actuate the detector device, the valve to outlet 12 remains closed while that to the whistle is open. Consequently, when the gas is turned on it flows through the whistle and gives a warning.

Title: Improvements relating to information storage devices
Inventor: BIRT DAVID EDWIN
IPC: G11C7/02
Filed: 1963-07-16
Abstract: 1,090,133. Circuits employing bi-stable magnetic elements. ELECTRIC & MUSICAL INDUSTRIES Ltd. July 8, 1964 [July 16, 1963; Nov. 15, 1963], Nos. 28091/63 and 45135/63. Heading H3B. A word organized information storage apparatus having a plurality of thin film magnetic storage elements E (Fig. 6), and having digit and sense conductors D, S arranged so that coupling between them is in opposite senses in different parts of the device, has trimming devices M associated with each digit conductor and being adjusted or adjustable to reduce further the coupling between the digit sense conductors. The mutual inductance between the sense and digit conductors may be reduced by the reverse looping of the sense conductors S as shown while fine adjustment to zero is provided by variation of the trimming devices M which are then secured in this position. One form of trimming device comprises a rotatable disc 7 (Fig. 1) half of which is coated with a conducting coating 8 the disc being arranged adjacent to pairs of connectors 3, 4 connecting the digit and sense conductors of a column of storage elements in each a pair of magnetic memory plans 1, 2 of the storage apparatus. In another arrangement (Fig. 2, not shown) adjustable bridge members (10), (11) are provided between overlapping lengths of sense conductors (4) on the outer surface of the upper and lower plans of the apparatus. The members (10), (11), are adjusted to balance the coupling between the sense and digit conductors (3), (4) and are then secured in position or replaced by solder. In another arrangement (Figs. 4 and 5, not shown) adjustment of the mutual inductance between the sense and digit conductors of two storage planes is obtained by having portions of the connecting conductors leading to the digit and sense conductors movable. Variation of the distance between a conductor portion leading to e.g. a digit conductor and a conductor portion leading from the return portion of that digit conductor then varies the extent to which the fields produced by current in these two movable conductor portions are self-cancelling and hence the value of the resultant field linking with the adjacent sense conductors.

Title: Improvements in or relating to pulse generators
IPC: H03K3/30
Filed: 1959-08-19
Abstract: 925,706. Circuits employing bi-stable magnetic elements. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 19, 1959 [Aug. 22, 1958], No. 28366/59. Class 40 (9). [Also in Group XL (c)] A pulse trigger, amplifier or gate comprises two bi-stable magnetic elements 1, 11, Fig. 4, and a transistor 2 so arranged that the two elements change from " 1 " to " 0 " in sequence in response to a single trigger pulse on terminal 4. Element 11 does not start to change until element 1 has finished. Element 1 is normally re-set to " 1 " by winding 6. A trigger pulse in winding 7 starts the change from " 1 " to " 0." Base current increases and the collector current in winding 9 completes the change. The second element 11 is biased against a change to " 0 " by winding 14 and the element does not change till the base current falls. The transistor is biased so that the collector current remains substantially constant throughout the operation. When both cores 1, 11 have switched the transistor 2 no longer conducts and core 11 is reset by the bias current in winding 14. The Specification describes a pulse amplifier with a transistor and only one bi-stable magnetic element. In Fig. 1, the element 1 is normally set to "1 " by a reset winding 6. A trigger pulse in winding 7 starts the change from "1 " to " 0 ". The collector current of transistor 2 completes the change and itself constitutes the output pulse. Amplifiers may be used in pairs with the collector of one connected to the emitter of the other, as shown in Fig. 3. Thus in Fig. 2, which shows the control circuit of a magnetic memory storage device described in Specification 841,449, a pulse may be sent along one of twelve cores A1 to A12 by simultaneously marking an amplifier in each group P1 to P4 and Q1 to Q3 by a trigger pulse.
