Title: Weaving looms
IPC: D03D47/24
Filed: 1955-09-27
Abstract: 787,697. Warp stop-motions for looms. SULZER FRERES SOC. ANON. Sept. 27, 1955 [Oct. 2,1954; Oct. 23,1954], No. 27526/55. Class 142(2) In a gripper-shuttle loom in which the shuttle is picked in one direction only and is returned on a conveyer to the picking side of the loom, when a warp thread breaks the loom stops with the main shaft in a particular sector of the working cycle, a control device being provided for angularly adjusting that sector. The control device permits adjustment in dependence on the braking angle appropriate to the loom speed. Looms driving and stopping. A motor drives the main shaft 15 through vee belts and a coupling. Levers at each side of the loom operate the coupling and a brake. The brake can be released by moving either lever, without re-engaging the coupling, so that the loom can be turned over by a hand-wheel. Loom shedding (Fig. 2). Shafts 41. 42, driven by gears 43 from the main shaft 15 at one quarter of the speed of the main shaft, carry cams 45a-45d and 46a-46d which actuate levers 47a-47d connected to the heald shafts 18a-18d. Warp stop-motion. In one embodiment (Fig. 4), when a warp thread breaks a dropper 76 engages a contact bar 77 in a circuit containing a solenoid 80 which contacts the application of the brake. The circuit is not completed, however, until the main shaft 15. and consequently the heald shafts, are in their required positions. The circuit is completed when a contact 68 on a disc 67 mounted on the shaft 15 engages two fixed contacts 69. Completion of the circuit energizes the solenoid 80 which turns a lever 65 thereby releasing an arm 62 so that the spring 59 applies the brake. In a further embodiment (Fig. 13), the shaft 15 carries a cam 108 adjustably mounted thereon and on breakage of a warp thread, the solenoid 80 is energized and lowers an arm 99 into the path of a lever 92 which is rocked by the cam 108. The arm 99 turns a lever 103 on the stop shaft 66. By setting the cam by means of a scale 106 the shaft 15 stops in the required angular position. The cam 108 may be on a separate shaft rotating in synchronism with shaft 15.

Title: Production of organosilicon compounds
Inventor: ANDERSON ROBERT CRAIG
IPC: C07F7/08
Filed: 1962-07-18
Abstract: Organosilanes and organohalosilanes are prepared by reacting a siliceous material with an alkylaluminium halide in the presence of a compound containing at least one Si-H group. The siliceous material may be free silica, e.g. silica gels, fume silicas and diatomaceous earths such as kieselguhr, or combined in the form of natural or synthetic silicates, e.g., bentonite, talc, china clay, albite felspar, olivine wollastonite, mica, chrysotile asbestos, anhydrous sodium silicate and residues obtained by extracting metal oxides from silicates.  The material is preferably non-crystalline and of high specific surface area, e.g. 0.32 sq. m. per gm., and is preferably heated to dry before use.  Suitable organoaluminium compounds are methyl aluminium dichloride, dimethylaluminium chloride, methyl and butyl aluminium sesquichlorides and the bromides, iodides and fluorides.  An aluminium trialkyl and/or aluminium halide may also be present. The alkyl aluminium halide may be formed in situ by the reaction of an alkyl halide and aluminium in the presence of a catalyst, e.g. aluminium chloride, iodine and small quantities of alkyl aluminium halides.  Suitable Si-H compounds are MeSiHCl2, SiHCl3 and tetramethylcyclo-tetra-siloxane. The SiH compound may be formed in situ by the action of a metal hydride on a silicon halide. The reaction may be effected at temperatures of, for example, 0 DEG to 200 DEG C. or higher, preferably 100 DEG  to 200 DEG C. The proportion of Si-H compound may vary widely, e.g. from 2 to 100% by weight of the aluminium compound.  The preferred molar range of Si to Al is from 1:2 to 4:1.  The products in Examples 1 to 10 are tetramethyl silane and in Example II n-butyl silanes. Specification 805,674 is referred to.

Title: Improvements in air cooling for internal combustion engines
IPC: F01P7/02
Filed: 1934-09-27
Abstract: 444,599. Cooling cylinders. ROWLEDGE, A. J., Ellerslie, Trowels Lane, Mickleover, Derbyshire. Sept. 27, 1934, Nos. 27766 and 33682. [Class 7 (ii)] An aircraft cowling for a V-engine has a chamber at the rear into which air is introduced by the slipstream and from which it passes to the space between the V, and thence, over or past the cylinders, to an exit in the rear of the cowling. In an X-engine, seen in elevation and plan in Figs. 2 and 3, air is delivered by a diverging scoop h to a chamber h<3>, whence it passes to the V-spaces above and below the banks of cylinders; it then flows past the cylinders into the side V's and is discharged through substantially vertical slots h<8> by the slip stream. Baffles deflect the air on to the cylinder heads and the cylinder fins which are arranged transversely of the cylinder axes. The entrance to the scoop h may be adjustable. In a modification, air enters the lower V-space by a number of scoops leading from the scoop h and each delivers a stream of air opposite a separate pair of cylinders.

Title: Methods of, and apparatus for, purifying and drying oil separated from aqueous emulsions
IPC: C10G33/06
Filed: 1926-09-13
Abstract: 282,321. Ellis, G. B., (American Sheet & Tin Plate Co.). Sept. 13, 1926. Fats and fatty oils, recovering and purifying.- Oil, such as palm oil, separated from an emulsion of oil and water, is purified and dried by heating the oil until substantially all the water content is changed to vapour and separating the vapour from the oil. The oil, after passage through a screen 48, Fig. 2, which removes solid matter, may be collected in a tank 50 fitted with a steam coil 51, from which it is pumped through a coil 54 located in a steam heated drying drum 55 which raises its temperature to 300‹ F. and vaporizes its water content before it is discharged into a stack 56. The water vapour passes up the stack, and the dry oil flows through tanks 59, 60, maintained at 300‹ F., to a centrifuge 62 for final purification. The invention is described as one step in a process for the removal, purification and recovery of oil from tin plate. As shown in Fig. 1, tinned plates form a pot A, after passage through a body of palm oil 9, are fed into a washing-tank C filled with a hot soda ash solution and supplied constantly with water from a pipe 12 and with further soda ash as required. The plates are pressed through the solution by pairs of rolls 15, 16, the lower roll of the first pair and the upper roll of the second pair being of smaller diameter and having a greater surface speed than the remaining rolls and being fitted with a fabric or rubber covering 17, whereby the plates are scoured and freed from oil, and an emulsion of the latter with the solution is formed. Similar pairs of rolls 19, 20, 21 serve to polish and dry the plates before they pass to a branner 24. Emulsion from the tank C, zinc chloride and other soluble impurities having passed from the oil into the aqueous solution, overflows through a pipe 29 and passes by a trough 31 into the heating and mixing chamber 33 of a tank D, Fig. 2, where a measured quantity of sulphuric acid is added from a tank 42 by a pump 43, and into which steam is passed from a pipe 39 to heat the mixture to, say, 140‹ F. The emulsion, thus broken, overflows into a chamber 34<a> and separates by gravity, the oil rising to flow over the inclined top of a wall 35 into a chamber 35<a>, this action being assisted by a steam coil 38, and the water passing away by a pipe 45, the top of which is about 1¢ ins. below that of the wall 35. Acids other than sulphuric acid, nitre cake, waste pickle liquor, lime, calcium chloride, iron or sodium sulphate, or alum may alternatively be used to break the emulsion, but in some cases the oil then settles out with any precipitate formed and the water rises in the chamber 34<a>; or the emulsion may be broken by centrifugal means, or the oil be extracted therefrom by a solvent. The oil collecting in the chamber 35<a>, which contains about 60 per cent of water, and is heated by the steam coil 41, is dried and purified as above described.
