Title: Improvements relating to organosilicon compounds
IPC: C07F7/18
Filed: 1957-04-05
Abstract: Organosilicon compounds, soluble in water but insoluble in benzene, are made by (1) interacting, in the presence of an acidic catalyst, ethylene glycol with an alkyl alkoxysilane composition consisting essentially of 50 to 100 mol. per cent of a monoalkyltrialkoxy silane, 0 to 50 mol. per cent of a trialkylalkoxysilane, 0 to 10 mol. per cent of a dialkyl dialkoxy silane and 0 to 10 mol. per cent of a tetra-alkoxy silane, the Si-bonded alkyl radical being methyl or ethyl and the alkoxy radical containing 1 to 5 C atoms, there being present more than one OH group of the glycol for each alkoxy radical in the silane or silane mixture; and (2) thereafter heating the mixture at a temperature below 100 DEG  C. while simultaneously removing the alcohol formed.  The alkoxysilanes, made in known manner from the corresponding chlorosilanes and containing residual HCl, may be used for reaction with the glycol.  The removal of alcohol and HCl may be effected under reduced pressure and the remaining traces of HCl may be neutralized with CaCO3.  The resulting low viscosity liquid is a silane; thus the reaction of ethylene glycol with a mixture of methyltriisopropoxy- and trimethylisopropoxy-silanes yielded a mixture of silanes of the formul : <FORM:0813520/IV (a)/1> When the reaction products are dissolved in water in amounts of 0.5 to 100 per cent by weight of the water and reaction product and applied to materials to be sized or waterproofed, siloxanes and formed on air-drying or heating of the treated products.  In examples, ethylene glycol is reacted with (1, 2) a methylisopropoxysilane mixture; or (3) methylmethoxysilane, to give a water-soluble product; in comparison ethylene glycol is reacted with (4) a methylchlorosilane mixture to give a water-insoluble product; and (5) methyltriisopropoxy silane at 160 DEG  C. to give a gel. Uses.-For rendering porous materials, e.g. asbestos shingles, glass cloth and masonry, water repellent; for stiffening porous materials, e.g. bias-cut glass cloth; and for sizing glass fibres and glass cloth.  Specification 663,599 is referred to.ALSO:Aqueous solutions of the reaction products of ethylene glycol with one or more methyl- or ethyl-alkoxy silanes, the alkoxy group having from 1 to 5 carbon atoms (see Group IV (a)) are used for stiffening porous materials, e.g. bias-cut glass cloth, and for sizing glass fibres and glass cloth, particularly to prepare them for further treatment with phenolic resins or other organopolysiloxanes.ALSO:Masonry, such as concrete blocks, brick and cement, and asbestos shingles are rendered water-repellent by treatment with an aqueous solution of the reaction product of ethylene glycol with one or more methyl- or ethyl-alkoxysilanes (see Group IVa).

Abstract: 168,107. Igranic Electric Co., Ltd., (Cutler Hammer Manufacturing Co.). April 22, 1920. Vacuum tubes.-Relates to a thermionic relay or control device of the type in which both halfcycles of an alternating-current supply are passed through the control tube; As shown in Fig. 1, the tube 10, which may be vacuous or may contain gas or vapour, is in series with the load in an output circuit L forming the secondary of a transformer T, the primary of which carries the input current to be controlled. The two main electrodes 11, 12 are heated by batteries 17, 18 and act alternately as anode and cathode for the controlled current flowing in the circuit L. The control elements or grids 13, 14 are connected to the filament-electrodes through potentiometers 19, 20. By arbitrarily adjusting the potential of the grids relatively to their respective filaments, the effective resistance of the tube 10 is varied to achieve the desired control. With a positive grid potential, it is stated that a substantial amplifying effect is obtained. Additional plates 15, 16, connected respectively to the grids and filaments, may be provided to minimize the effects of collision between the main electronic stream and any subsidiary stream that may exist between the acting anode and its associated grid. In the modified form shown in Fig. 2, an alternating supply is used both for heating the filaments and for providing the controlling grid potentials.

Patent GB-114785-A (GB)
IPC: B60T13/62
Abstract: 114,785. Turner, W. N. May 25, 1917. [Convention date]. Fluid-pressure. - Relates to straight air emergency systems in which the emergency brake pipe 2 is adapted to supply pressure air from the main reservoir 5 through the emergency valve 4 and the rotary-valve chamber 14 of the driver's valve to the straight air pipe 3 in making straight air applications. To avoid the tendency of the pressure in the straight air pipe to blow the rotary valve 15 off its seat when, Ly venting the pipe 2 to the exhaust port 21, an emergency application is effected following on a straight air application, a port 23, Fig. 2, in the valve 15 is arranged to register with the straight air pipe 3 to equalize the pressure on this valve. If, however, the emergency valve should fail to move, this would permit exhaust of the brake cylinder through the straight air pipe 3 and the exhaust port 21. According to the invention, escape of air from the brake cylinder in this way is prevented by arranging a check valve 24 in the passage 2' leading from the valve chamber 14 to the emergency pipe 2. In the running position of the parts, Fig. 1, pressure air is supplied from the reservoir 5 to the valve chamber 9 and by port and passage 17, 18 to the piston chamber 7, thence to the pipe 2. The brake cylinder is connected by the valve cavity 12 to the straight air pipe 3 which can be connected to the exhaust port 21 as shown for release or to the valve chamber 14 when a straight application is desired. When the pipe 2 is vented for an emergency application, the slide valve is moved to uncover the brake cylinder passage to the valve chamber 9.

Abstract: 115,157. Fairweather, W., (Singer Manufacturing Co.). July 26, 1917. Sewing - machines; cords, braids, and the like, attaching; workguides. - Relates to sewing - machines adapted to secure staystrips, e.g. at the junction between the bib and body portions of an overall, and consists in the means provided for moving the edges of the stay-strip away from the stitching-devices near the end of the operation in order to allow the operator to turn under the end of the strip and finish the attachment by hand sewing without having to unpick the stitching. In one form, the throat plate 3, Fig. 6, is cut away in front of the needle-holes 2, to provide a recess 4 bounded by an end vertical wall 7, and two convergent side walls 5, 6 joining two walls 9, 10 parallel to the line of feed. The walls 5 and 6 are chamfered at 5<1>, 6<1>. The stay-strip is led through a guide 12, Fig. 2, having folding edges 14 and a spring tongue 15 which terminate in front of the flat tubular delivery end 16 which is bevelled to fit between the surfaces 5, 6. The guide is adjustably secured to a plate 20 which is secured to a rock-shaft adapted to be actuated by a spring- controlled pivoted lever 32 having, at its upper end, a cam-slot engaging a roller on an arm 29 carried by the rock-shaft. A hemmer for the edge of the bib portion is hinged to a removable section of the cloth plate which also carries an edge guide for the body portions of the garment. Normally, the guide 14 delivers the strip on a level with the throat plate and the strip is then secured by the needles as shown in Fig. 4. Towards the end of the process, the lever 32 is shifted to depress the guide between the surfaces 5, 6 and cause the strip to miss the needles as shown in Fig. 2. For some purposes it may be necessary to move only one edge of the strip. In this case, one of the converging surfaces 5, 6 is omitted. In a modification, the crimping of the strip is obtained by fingers 112, Fig. 10, on the guide co-acting with recesses 114, Fig. 9, on the throat-plate. In a further modification, the tubular portion of the guide is provided with an aperture through which a rod 212, Fig. 13, is adapted to be passed when it is desired to withdraw the edges of the strip out of range of the needles.

Abstract: 494,021. Partly - electromagnetic switches. CRABTREE & CO., Ltd., J. A. (Schiele Industriewerke) April 23, 1937, No. 11616. [Class 38 (v)] In a multi-pole overload switch a housing a is divided into chambers c, d, e, corresponding, e.g. to the three phases of a three-phase supply, and each chamber contains a coil i which serves to heat a thermal element h, to energize an electromagnet m and to generate a magnetic blow-out field for switch contacts v, t. A moderate overload causes one or more of the thermal strips h to bend to the right and actuate a bar to cause contacts g in a holding circuit to open, which in turn causes the contacts u to move away from the fixed contacts 8. An excessively high overload causes one or more armatures n to be rotated about its pivot o by its magnet m and to actuate a bar l which similarly causes the contacts g to open.
