Title: Process for the hydrolysis of organo-fluorosilanes
IPC: C07F7/21
Filed: 1957-07-09
Abstract: In hydrolysing organofluorosilanes with aqueous caustic alkali used in amount in excess of that theoretically required for the complete hydrolysis, and acidifying the mixture prior to separation of the organosilicon compound(s) (see Group IV (a)), the fluorine is recovered as alkali metal fluoride.  In a preferred embodiment the hydrolysis is effected in two stages, firstly by hydrolysing an organic solvent solution of the silane with aqueous caustic soda in amount less than that theoretically required, separating the solvent layer from the aqueous layer from which the fluorine is recovered in the form of pure Na2F2 in known manner; and secondly by completing the hydrolysis by adding excess NaOH to the solvent layer from the first stage and, after acidification, e.g. with HCl, separating the solvent layer from the aqueous layer from which the residual fluorine is recovered as Na2F2 together with the alkali metal salt of the acid used, e.g. NaCl.  Inorganic acids specified are HCl, H2SO4 and H3PO4.ALSO:Organo-fluorosilanes are hydrolysed with aqueous alkali metal hydroxide in amount in excess of that theoretically required for the complete hydrolysis of the fluorosilanes, with subsequent acidification to a pH in the range of 3.0 to 6.0 and separation of the resulting siloxane or silanol.  Separation of the organosilicon compound may be effected by allowing the reaction mixture to stand, but preferably by extraction with a solvent, e.g. hexane, cyclohexane or other aliphatic hydrocarbon, an ether, ketone or ester, benzol or toluene, with subsequent distillation of the solvent under vacuum at 30 DEG  C. or less to yield a monomer or lower polymer.  In a modification the hydrolysis is effected in two stages, firstly the silane is dissolved in an organic solvent, hydrolysed with aqueous caustic alkali in amount less than that theoretically required for the complete hydrolysis, and the aqueous and organic solvent layers are then separated; secondly excess aqueous caustic alkali is added to the organic solvent layer from the first stage to complete the hydrolysis, acid being added to give a pH of 3.0 to 6.0 and the organic solvent layer is then separated from the aqueous layer. Acids specified are HCl, H2SO4, H3PO4, CH3.COOH and (COOH)2.  In examples the above methods are used to hydrolyse (1) (C2H5)2SiF2 to yield a liqui mixture of cyclic trisiloxanes and linear hexaethyltrisoloxane - diol; (2) (C2H5)3SiF to yield (C2H5)3SiOH; (3) (C2H5)2SiF2 to yield the liquid polymer (C2H5)2SiO0.6(OH)0.8; (4, 5) (C2H5)2-SiF2 and (C2H5)3SiF to yield liquid polysiloxanes containing 0.6 and 0.7 OH groups per Si atom; (6) (CH3)2SiF2 to yield a liquid siloxane containing 6.3 per cent SiOH groups; (7) (n-C3H7)2SiF2 to yield the di-n-propylsiloxane; (8) (C6H5)2SiF2 to yield (C6H5)2Si(OH)2, M.P. 142 DEG  C.

Title: Apparatus and method for trimming plastic articles
IPC: B23D31/00
Filed: 1975-05-22
Abstract: 1494529 Trimming moulded articles MONSANTO CO 22 May 1975 [23 May 1974] 22051/75 Heading B5A Flash 13 is trimmed from articles 11 which are being transported along a path 18 by guide members, e.g. rotating wheel 28 and stationary member 144, by means of a knife 12 which is retractible to allow the articles to pass untrimmed if equipment downstream becomes blocked. In this event the articles are conveyed by engagement of the flash portions 13 by a discharge guide wheel 32 to a shoot 36 for recycling. Normally only the flash takes this course after separation of the article. The knife 12 is adjustably bolted between two plates 40, 42 and this assembly is located by pins on a slider 86 and secured by bolts operated by hand wheels 134, 136. If the blade assembly sticks when it is to be changed the bolts 134, 136 are screwed into two other holes 141, 143, (Fig. 5, not shown) to bear on the slider and force the knife assembly away. The slider is advanced and retracted by a toggle linkage 94 worked by a pivotally mounted fluid motor 101. The motor may be controlled to automatically retract the knife if there is difficulty in transporting the articles past the knife and the torque measured on the drive shaft of the guide wheel 28 becomes too great. If an article becomes jammed along path 18 the guide member 144 may be retracted to free it by releasing hand operated toggle clamps 166 and bolts passing through slots 152 in the member 144. The articles are fed to the trimming device by a conveyer comprising a screw 24 and a stationary member 26 which has a retractable portion 21 for rejecting articles which are unsuitable for trimming.

Title: Improvements in or relating to cationic urea-formaldehyde resins and preparation thereof
IPC: D21H17/50
Filed: 1954-07-28
Abstract: A cationic resin which is of improved paper retention quality is obtained by adding a completely water-miscible alcohol to an aqueous solution of a urea-formaldehyde resin modified by a water-soluble polyfunctional organic nitrogen base, and separating the resulting precipitate.  Suitable alcohols are methanol, ethanol, propanol, isopropanol and tert.-butyl alcohol. The term "urea" includes urea and/or thiourea, and any methylene-yielding substance may be used instead of formaldehyde. The organic nitrogen base may be alkylenepolyamines, e.g. ethylenediamine, 1,3-propylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, or polypropylene- or polybutylene-polyamines; guanidines, biguanides, guanylureas and their salts; condensation products of alkylenepolyamines with halohydrins; mono- and di-alkylolamines and their water-soluble condensation products with aldehydes.  The modified resins are prepared as described in Specification 663,736. The yield of precipitate may be varied from about 20 to 60 per cent of the starting resin solids.  The filtrate may be treated to produce further resin to which further alcohol may be added; e.g. the filtrate may be concentrated to about 40 to 50 per cent solids, the ratio of urea to formaldehyde adjusted and the solution polymerized as for the original resin with or without a fresh charge of any of the components.

Title: Improvements in or relating to electric pulse generating apparatus employing transistors
Inventor: BURGESS PHILIP HUGH GEORGE
IPC: H03K3/30
Filed: 1957-07-12
Abstract: 841,307. Transistor pulse generating circuits. GENERAL ELECTRIC CO. Ltd. July 9, 1958 [July 12, 1957(2)], Nos. 22198/57 and 22199/57. Class 40(6). A pulse generator comprises a capacitor connected through a Zener diode to the base of a transistor and to a charging circuit, the arrangement being such that when the capacitor charges sufficiently the diode breaks down causing the transistor to conduct, the resulting collector current causing the capacitor to be discharged. In the Figure, a capacitor 47 charges through a resist- or 42 until a Zener diode 48 breaks down. A normally non-conducting transistor 33 is thus caused to conduct and apply a pulse through a transformer 44 to a further transistor 32 which discharges the capacitor 47 and so causes transistor 33 to cut off and recharging of the capacitor to recommence. The resulting pulse output from the transistor 33 causes a normally non-conducting transistor 51 momentarily to conduct and so discharge a capacitor 62. This causes a normally conductive Zener diode 63 to be rendered non- conductive and a normally conductive transistor 52 to be cut off. The capacitor re-charges through resistor 56 until the Zener diode 63 breaks down whereupon the transistor 52 again conducts. A delayed and lengthened current pulse accordingly appears in the collector circuit of transistor 52 and this may be used to operate a polarized relay 59. In an alternative circuit (Fig. 7, not shown) the transformer 44 is replaced by a relay winding, one contact of the relay being used to replace transistor 32 and discharge the capacitor 47 when transistor 33 conducts and the other contact being used to render transistor 51 conductive while transistor 33 conducts. The repetition frequency of the pulses in this circuit may be varied by adding capacitance in parallel with capacitor 47. Specification 835,602 is referred to.

Abstract: 626,621. Microscopes. CENTRE NATIONAL. DE LA RECHERCHE SCIENTIFIQUE. Aug. 30, 1945, No. 22378. Convention date, Sept. 1, 1944. [Class 97 (i)] A microscope is characterised in that an image of a polarising device, e.g. a polarising biplate disposed in the light path between the light source and the condenser of the microscope is formed by the condenser in the object plane of the microscope. As shown in Fig. 2, light from a source 9 is polarised at 1 and reflected at 8 so that the polariser 1 is imaged by the condenser 2 in the plane of the specimen 5, and observations are made through the objective 6 and eye-piece 7 of the microscope. The polariser 1 may consist of juxtaposed pieces a, b, Fig. 4, of dichroic film with their principal sections X, Y orthogonal. By rotation of the polariser 1, which is also movable in two orthogonal directions so that the image of the dividing line c of pieces a, b may intersect the specimen, the dichroic property thereof may be determined. Alternatively, the specimen may be rotated or a mica half-wave plate disposed at 11 may be rotated for the same purpose; the biplate 1 may also be replaced by a Nicol prism 13 and a half-wave plate 12. In order to determine the birefringence of the specimen 5, an analysing eyepiece may be used, a half-wave plate being disposed between the objective 6 and the specimen and coupled with the half-wave plate 11 so that they may rotate in unison. Using a Soleil biplate the rotation power of the specimen may be determined. Observations may also be made of the circular dichoism of the specimen using a double quarter-wave plate and an ordinary polariser. To avoid elliptically polarising the light by reflection at 8, two relatively inclined mirrors may be used or the light-source may be disposed along the microscope axis. The Specification as open to inspection under Sect. 9] states that the polarising device may be replaced by a grid, an index, a photograph, a spectrum or other comparison object. This subject-matter does not appear in the -Specification as accepted.
