Patent GB-636905-A (GB)
Title: Improved manufacture of organosilicon resins
IPC: C08G77/00
Filed: 1947-07-03
Abstract: An organo-silicon resin is manufactured by co-hydrolysing and co-condensing organo-silanes of the general formula CH3SiX3, C6H5SiX3 and (CH3)2SiX2, where X is an alkoxy radical or a chlorine atom, to form a polysiloxane in which essentially all the structural units are CH3SiO1,5, C6H5SiO1,5 and (CH3)2SiO and in which the silicon atoms of the various siloxane units are linked together in an alternating lattice of oxygen and silicon. The products are suitable for mouldings, adhesives, varnishes or paints, laminates, and insulating bars.  The mixed organo silanes are preferably hydrolysed by a two-phase mixture of water and di-ethyl ether, ethylene glycol di-ethyl ether or dioxane, alone or mixed with hydrocarbons, e.g. toluene.  The products are increased in viscosity or cured to solids on heating, and catalysts such as paint driers or triethanolamine may be added. Suitable fillers are cellulose ethers, metals, asbestos titania, diatomaceous earth, pigments, glass fibre, and laminates may be formed of glass fabric, or glass or mica flakes.  In examples a mixture of methyl silicon trichloride, phenyl silicon trichloride, and dimethyl silicon dichloride is hydrolysed with a two-phase system of water, toluene, and diethyl ether and/or ethylene glycol diethyl ether.  The products are used as solutions in toluene (1) and (2) mixed with asbestos and calcium stearate in moulding insulating bars; (2) also in paints, with a titania pigment; (3) and (4) in forming glass fibre laminates, using a triethanolamine catalyst in (3); (5) to form glass fibre laminates, with or without triethanolamine, and in making insulating bars with a diatomaceous earth filler. Specifications 591,221 and 607,022 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the use as starting materials of organo silicon derivatives having as hydrolysable radicals aroxy or amino radicals.  This subject-matter does not appear in the Specification as accepted.

Patent GB-736636-A (GB)
Title: Improvements in or relating to the spinning of viscose
IPC: D01D5/06
Filed: 1953-06-26
Abstract: <PICT:0736636/IV (a)/1> Apparatus for the manufacture of artificial filaments, particularly regenerated cellulose filaments from viscose, comprises a container for a spinning bath, a spinning jet in the container and below the working level of the surface of the bath, means for feeding spinning solution to the jet, a tubular conduit in line with the jet and having one end wholly below the working level of the surface of the bath and the other wholly above it, the interior of the conduit being in communication with the bath, and means for drawing filaments from the jet through the conduit, the arrangement being such that, in operation, coagulating liquid is drawn through the conduit solely by the drag of the filaments. Preferably, the conduit opens into the bath near the point of extrusion.  The height of the open end of the conduit above the working level of the surface of the bath is preferably less than 6 inches and may be even less than 2 inches.  At its lower end the conduit may be of enlarged diameter and may be conical in shape at that end.  Preferably it is arranged so as to encircle the jet face so that the coagulating liquid enters the conduit behind the plane of the jet face.  The preferred diameter of the conduit is within 40 per cent of that at which the maximum rate of flow of liquid through the conduit occurs under the other conditions prevailing.  The bulk of the coagulating liquid travelling with the moving filaments may be removed at a level below that at which it would fall away under gravity alone.  For this purpose, a fixed or moving member, e.g. a free-running or positively driven roll, may be positioned so as to contact the filaments above the open upper end of the conduit, or the conduit or an extension thereof may be provided with openings in its side above the level of the spinning bath, through which coagulating liquid can be discharged back into the bath.  If desired, the filaments may be drawn through the conduit under such tension that they undergo a considerable degree of stretch.  As shown, a spinning assembly 13 comprising conduit 14, spinning-head 15 and jet 17 is situated in a tank 11 containing a spinning bath 12.  The filaments 18 pass upwardly through conduit 19 which has a conical lower end 21 encircling the face of the jet.  The conduit is slidably mounted in a mount 23 carried by bracket 24.  After leaving conduit 19, the filaments 18 pass over idler roller 25 which is at such a position that the filaments reach it before the major portion of the liquid carried up with them would fall away under gravity alone.  The filaments pass under a second idler roller 29 and then up to a godet wheel 32.  They pass round the godet and the skewed roller 33, and are then taken up on bobbin 34.  To obtain access to the spinning nozzle, roller 25 may be lifted with its dovetailed mounting 27 out of the support 28, and the conduit 19 may be raised until one of its projections 36 rests on ledge 37.

Filed: 1961-05-17
Abstract: 980,696. Change-speed and reverse gear; change-speed control. W. HOLZER. May 17, 1961 [May 17, 1960], No. 17964/61. Heading F2D. [Also in Division H2] Change-speed or reverse gearing for washing machines, &c. comprises an electric motor having a sliding mesh pinion fast upon its armature shaft, changes in the energization of the electric motor causing the armature to slide axially, as well as varying the torque of the motor, so that the pinion slides out of mesh with one driven gear and into mesh with another gear. In one form, an electric motor 1, Fig. 1, has an armature 2 fast on the shaft of which is a pinion 3, a spring 9 biasing the armature to the position shown so that the pinion meshes a gear 4 fast on a shaft 8 driving through a gear train 12 to an output shaft 13. In the position shown, the motor 1 is fed through a circuit including a resistor 10. On shorting the resistor 10 by means of a switch 11 to increase the field of the motor 1, the armature 2 moves upwardly against the bias of the spring 9 so that the pinion 3 no longer engages the gear 4 but instead engages a gear 5 of a reversing double gear in turn meshing a gear 7 fast on the shaft 8, which, together with the shaft 13, now rotates in the opposite direction. In a modification, Fig. 2 (not shown), two pinions of different diameters fast on the shaft of the armature 2 are selectively slidden into mesh with different diameter pinions fast on the output shaft 13, depending upon the degree of energization of the electric motor 1. In another modification, the armature 2, Fig. 3, of the electric motor 1 carries a pinion 3 selectively meshed with different ratio gear trains 31 . . . 35 driving to an output shaft (not shown) depending upon the degree of energization of the motor, controlled by resistors 19 . . . 23 in series which may be short-circuited by contacts 24 . . . 28 operated, e.g., by pushbuttons. A pawl 30 co-operates with a ratchet 29 on the armature shaft to retain the latter in a selected axial position, in mesh with one or other of the associated driven gear trains, and may be released by means not described feeding a pulse of current on actuation of one or other of the contacts 24 . . . 28. Alternatively, the pinion 3 may be axially positioned by the design of the armature and co-operating field structure of the motor, e.g. by multiple tapped windings.
