Filed: 1972-03-15
Abstract: 1349914 Treating textiles LUBRIZOL CORP 15 March 1972 [24 March 1971] 12156/ 72 Heading D1P [Also in Division C3] Soil release and durable press characteristics are imparted to textile materials (e.g. linear polyester fibres or a cellulose material) by applying thereto a composition comprising a textile resin and a polymer which is water soluble or capable of forming a stable aqueous emulsion and which contains units of the formula: where R 1  is H or a C 1 -C 7  alkyl group which may be substituted, R 2  is a divalent or trivalent hydrocarbon radical which may be substituted and X is 1 or 2. The textile resin is defined as a monomer or polymer which when applied to a textile material undergoes polymerisation or condensation and is transformed to the thermoset state e.g. an aminoplast resin. The composition may also contain a textile resin curing catalyst. Exemplified compositions comprise a) water b) polyethoxynonyl phenol c) dihydroxydimethylol ethylene urea or N-methylolacrylamide, d) zinc nitrate or magnesium chloride and e) one of a homopolymer of 2 acrylamido 2 methyl propane sulphonic acid or its sodium salt or a copolymer of the sodium salt with acrylic acid, maleic acid or diacetoneacrylamide. The compositions may be applied to the textile material (e.g. cotton, wool, jute, flax, viscose rayon, polyethyleneterephthalate, nylon or polyacrylonitrile) by dipping, spraying or padding and the treated fabric is cured at 130 to 200C, rinsed and tumble dried.

Title: Improvements relating to the manufacture of illuminating gas
IPC: C10K1/00
Filed: 1921-04-28
Abstract: 164,310. Soc. du Gaz de Paris. June 4, 1920, [Convention date]. Materials for purifying.-A process for the purification of illuminating gas consists in first treating the gas in a washer with a liquid consisting of a solution of a ferrous salt and milk of lime and then with the solid residue, filtered from the above-mentioned liquid, exposed to the air, and mixed with sawdust. In the first stage, the cyanogen in the gas forms prussiate of lime and remains in solution, and part of the sulphuretted hydrogen forms iron sulphide, which remains in the residue. In the second stage, the residue when exposed to the air forms a purifying material of ferric hydrate mixed with sulphur, sulphate of lime, carbonate of lime, &c., which removes the remainder of the sulphuretted hydrogen.

Abstract: 699,231. Loom brakes. FALLS FLAX SPINNING CO., Ltd. Feb. 9. 1951 [May 10, 1949], No. 12420/49. Class 142(i) [Also in Group XXXIV] A brake is actuated by a pivoted lever releasably connected to the starting handle of a loom and is arranged to release itself automatically when the lever is disconnected from the starting handle. A lever 18, pivoted on a stud 24, moves a bar 14 provided with a cam-shaped block 16 to operate a brake shoe 7. A releasable connection 27 connects the lever to the starting handle 21 and, when the loom is running, the handle engages an arm 29 and pivots the lever 18 so that the block 16 does not lift the brake shoe against a handwheel 10. When the handle is moved to stop the loom, the lever is pivoted in the opposite direction and the brake is operated. If the connection 27 is turned about its pivot to disconnect it from the handle 21, the shoe 7 will fall away from the wheel 10 and the inclined cam face on the block 16 will cause the lever 18 to swing to one side.

A work-transfer device for feeding articles W from a supply 1, Fig. 1, to a chuck or similar work-holder 2 comprises an oscillatable bracket 4 carrying a magazine 9. The bracket is moved by a connecting-rod 5 about the pivot 3 and during working operations occupies the broken line position where the magazine 9 is replenished from the supply 1. The magazine is exchangeably secured to the bracket by straps 10 and its lower part opens into a circular chamber 12, Fig. 2, carrying a plunger 15 the front blankengaging part of which is freely rotatable relative to the rear part. The latter is grooved for engagement by screws 22, Fig. 1, carried at the ends of arms 21 secured to a block 23 pivoted about a pin 24. An arm 25 also secured to block 23, Fig. 2, is adapted to be moved by an air-operated plunger 27. When a new workpiece is to be fed to the chuck 2, Figs. 1 and 2, the bracket 4 is rocked over against a stop 7 to bring the chamber 12 into line with the chuck as shown in Fig. 1. A workpiece W has been fed by gravity into the chamber 12, Fig. 4, and on feed movement of the plunger 15, is forced past a pair of spring-retaining fingers 18 into the chuck, the magazine is then moved away about the pivot 3. Pneumatic means may be used to feed the workpieces through the magazine and the plunger 15 may be moved hydraulically or electrically. The pivoting magazine part may be continually connected to the supply 1 by flexible means.

In a motor-driven inflatable craft comprising a U-shaped tubular body 1, the legs 2, 21 of which are connected at a certain distance from their ends by a tubular member 3, a framework 4, 41 disposed on the tubular body, and an additional frame or transverse members 5 disposed on said framework serving to support a propelling unit or units 7, the framework and/or the additional 'frame 5 are capable of being readily assembled or dismantled. The propelling unit 7 together with the propeller shaft 9, propeller 10, and steering arm 11 can be tilted vertically or alternatively the propeller shaft 9 with the propeller 10 can be independently tilted and also turned through the full circumference of 360 degrees. This arrangement facilitates steering and enables the propeller to be raised to avoid damage in shallow water. To give the boat an improved attitude at speed the bottom 16 is extended beyond the transverse member 3 as shown at 12 in Fig. 5. The extension may be stiffened by a detachable plate or members 13. The bottom 16 supports additional flooring, various forms of which are described, which flooring prevents the bottom assuming a corrugated shape when the craft is in motion..

Title: Device for reducing the rate of fire of automatic firearms
IPC: F41A19/03
Filed: 1928-05-02
Abstract: 290,662. S.A.F.A.T. Soc. Anon. Fabbrica Armi-Torino. May 20, 1927, [Convention date]. Machine guns.-Relates to devices comprising a toothed escapement wheel cooperating with an oscillating anchor, for reducing the rate of fire of automatic finearms, and consists mainly in the arrangement in conjunction with the escapement wheel of a diametral cam adapted to be struck eccentrically by a recoiling part of the firearm for rotating the escapement wheel always in the same direction, the provision of means for neturning the cam to the working position after each operation by the recoiling part, a.nd the construction of the device as a whole so that it can be detachably mounted on the firearm, and when detached will leave the firearm free to operate at its normal speed. As shown in Figs. 1 and 2, the escapement wheel 3 and the anchor 4 are mounted on pivots 2, 5 in a casing 1, which is detachably mounted on the frame 10 of the firearm by a bayonet-like joint 1<1>, 9'. A cam 6 projects from the escapement wheel into the path of a lug 13<1> on the striker 13; and a member 7 is slidably mounted on the casing 1 and is pressed against the cam 6 by a spring 8, thereby returning and maintaining the cam in the working position after each operation by the lug 13<1>. The member 7 is moved away from the cam 6 by the breech-block 12 when this block closes the breech. The lug 13<1> then strikes the cam 6, and the anchor escapement retards the firing stroke of the striker 13. When the striken recoils with the breech-block after the firing of a shot, the cam 6 is freed from the projection 13' and moved to the working position by the spring slide 7. Segments 3<x> of the escapement wheel are left without teeth so that this last movement of the cam is unimpeded by the anchor. In a modification, the spring slide 7 is pushed away by the cam itself when this is operated by the lug 13<1>. In another modification, the cam 6 is made up of two bevelled parts spring-mounted on the escapement wheel, to enable the projection 13<1> to operate the cam in one direction and to ride back over it. In a further modification, the cam is connected to the escapement wheel by a free-wheel device allowing transmission of movement in one direction only, and is operated by a shoulder on the breech-block. Two opposing springs control the cam and restore it to its normal position when freed by the shoulder of the breech-block.
