Title: Improvements in organo-siloxanes and methods of making them
IPC: C08G77/06
Filed: 1944-05-02
Abstract: Liquids comprising inter-condensed siloxanes which may be used as hydraulic fluids, insulating media, thermal expansion fluids, water-proofing agents or, after further polymerization, as coating and impregnating agents, are obtained by reacting at least two organo-siloxanes, one of which is substantially free of hydroxyl groups, in a homogeneous liquid phase in the presence of an acid catalyst at temperatures at which no decomposition or polymerization of the siloxanes takes place.  In examples: (1) a mixture of 4 parts by weight of phenyl ethyl silicone (300 cs. viscosity) and 1 part dimethylsilicone (450 cs. viscosity) containing less than 0.2 per cent hydroxyl groups was dissolved in two volumes of diethyl ether; the solution was saturated with hydrochloric acid and allowed to stand overnight.  A homogeneous liquid was obtained on boiling off the solvent; (2) 1.8 gs. phenyl ethyl silicone, 0.3 gs. dimethyl silicone and 0.1 gs. sulphuric acid were reacted similarly at 200 DEG C.; (3) the same compounds were reacted in presence of phosphoric acid; (4) the mixture comprised bis-trimethylsilicyloxide and dimethyl silicone; (5) bis-trimethylsilicyl oxide and bis-phenyl dimethyl silicyl oxide were reacted in presence of hydrogen chloride. Specifications 561,136, 572,331 and 583,875 are referred to.

Title: Apparatus or mechanism for the cutting and shaping of wooden bobbins, knobs, handles and the like
IPC: B27M3/30
Filed: 1922-03-27
Abstract: 199,789. Green, A., and Topham, R. H. March 27, 1922. Lathes. -- In a machine for making wooden bobbins, knobs, handles, and the like, a wooden bar held at one end by a headstoch 3 passes through a guide d carried by a saddle 4 which slides along a frame 6. The saddle engages the lead screw 9 by a worm wheel 8 mounted on a spindle 4a and alternately locked against rotation and allowed to rotate by the action of a pawl 7h. Whilst the spindle 4a is locked the saddle moves to the left, during which time the work is roughed out by a tool in the holder 24 and bored bv a drill 15. When the end of the spindle 7<a> meets the work, the spindle is pressed back, thus releasing the ratchet wheel 7k. The spindle 4<a> accordingly rotates, and by means of a cam 12 and a slide 11 moves a support 10<a> so as to bring shaping and parting tools (not shown) thereon into action, and at the same time presses a friction strap attached to the saddle into contact with the frame 6, so as to check any looseness. As the slide 11 recedes the arm 10e which is attached to the support 10<a> actuates an ejector 14. Prior to this operation a cam 15p on the spindle 4a withdraws the drill 15 into the interior of the spindle 7a, as shown. The saddle at each end of its travel engages lugs 20, 20<g> and operates a reversing clutch 17 driving the lead screw. Centres.-The bar is centred and driven by a hollow cone mounted in the spindle and provided with an internal taper screw thread.

Filed: 1947-04-01
Abstract: 622,618. Coal-cutting machines. SHEPPARD, W. V. April 1, 1947, No. 8856. [Class 68 (i)] A coal-cutting machine comprises a plurality of superposed horizontal cutting jibs, each carrying a chain cutter and mounted on a common supporting structure located between upper and lower adjacent jibs and rooted to the machine body intermediate the ends thereof, a vertical shearing jib carrying a chain cutter and connected to the supporting structure extraneously of the machine body, and driving mechanism in the machine body for operating said chain cutters. In Figs. 1, 2 and 3, the machine body 10 has a projecting supporting structure 13 for upper and lower cutter-chain jibs 14, 15, and a shearing cutter chain jib 17 is carried by a cantilever arm 20 riding on the floor and pivoted at 21 to the structure 13 so that the shearing jib may trail behind the horizontal jibs in either direction of working ; a stay may be detachably secured by pins to the structure 13 and cantilever arm 20 to give rigidity. The cutter chain on the shearing jib is driven by a shaft 25 which detachably connects a driving head 24 on the jib to either of two driving points 26, 27, on the machine body according to the direction of travel of the latter. A wedge member may be inserted between the cantilever arm 20 and the shearing jib 17 to tilt the latter to either side of the vertical ; the shearing jib may also be capable of swivelling on the cantilever arm. The machine is traversed by means of a haulage winch 38, and may be provided at the front end with a detachable plough 40 and at the rear end with a two part detachable curved chute 42 secured at 43, 44, and guiding the cut coal to a conveyer 12 ; means may be provided for jolting the chute. Gearing controls 46 may be provided at each end of the machine. The supporting structure 13 may carry fixed picks to break down coal between the cutter-chain jibs 14, 15. For use in thick seams, a further horizontal cutter jib 70, Fig. 7, may be supported by a turret 72 on the machine body, and carry above or below it a rotary cutter 71, the jib 70 being connected to the shearing jib by a stay 78 ; a rotary cutter 71 may also be provided above the jib 14 of Figs. 1 to 3. The cantilever arm 20 may be omitted, the shearing jib then being mounted directly on the supporting structure 13 and its cutterchain being driven either from the outer sprockets of the undercutting cutter chains through gearing, or by a shaft extending through the supporting structure 13 ; in the latter case, the shaft may be enclosed in a tubular housing supporting the shearing jib, and the housing may be adjustable to position the shearing jib at either side of the vertical.

Each element 14, Fig. 3, of a stack in a casing (not shown), comprises an annular sheet of resin-impregnated paper 21 and an annular sheet of aluminium 20, their outer peripheries being united by crimping. The aluminium sheet 20 has radial grooves 22 facing the paper and communicating with an annular groove 24 at its inner periphery, the outward ridge 25, corresponding to the groove, serving to engage the paper of the next upper element, thereby to seal a filtrate space 27. Liquid passing through the discs 21 flows along the grooves 22 to the grooves 24 and thence through apertures 30 to the spaces 27. The discs 20 engage a rod 15 but the portions 26 are perforated at 28 to connect the spaces 27. A stack of elements is secured on the rod 15 between clamps 16 and 17 (17 not shown) by retaining studs 18, the clamp 16 having apertures 31, Fig. 2, providing commimication with an oil outlet from the surrounding casing. In Fig. 4 (not shown) the ridge is formed with a number of flat surfaces to assist its clamping action. In Fig. 5 the sheet 20b is perforated and two paper sheets 21b are provided, the filtrate flowing into the filtrate outlet space between tongues 41b on the sheet 20b which separate the inner peripheries of the sheets 21b. In a further embodiment the elements are inverted and the inner periphery of the groove 24 is folded back onto the sheet 21, and in an embodiment similar to Fig. 3 the groove is shaped differently. The outer peripheries of the two sheets may merely abut so that fluid pressure causes sealing. The non- permeable sheet 20 may have a thickness of 0À005 inch and the sheet 21 a thickness of 0À2 inch. Inter-surface flow of fluid may be assisted by indentations, discrete or otherwise, in the permeable sheet, e.g. in the form of circularly- and radially-disposed grooves.
