Title: Improvements in electrically operated driving and reversing mechanism
IPC: F16H37/00
Filed: 1922-01-04
Abstract: 195,654. Vickers, Ltd., McKechnie, Sir J., and Bateman, L. H. Jan. 4, 1922. Planning.-A planing machine is driven by two electric motors which are automatically controlled so as to produce different speeds for the forward and return strokes. The two motors s, t, Fig. 1, have their shafts q, r, Fig. 3, connected by worm wheels o, p and differential bevel wheels h, i to a shaft c which thus revolves at a speed equal to the difference of the motor speeds. The shaft c is coupled to a pinion b which drives the planing- table through rack or screw gearing. The inequality of speed is set up by inserting resistances alternately in the motor field circuits, the change over taking place automatically at the end of each stroke. The gearing is enclosed in a case lubricated by an oil-pump. A balancing regulator is provided for bringing the planer to rest or for very slow movement.

Title: Improvements in the manufacture and production of organic acids
IPC: C07C51/41
Filed: 1931-04-07
Abstract: Organic acids are obtained by treating products of the destructive oxidation of liquid or solid non-aromatic hydrocarbons, especially such as contain esters, estolides, lactones, or lactides, in a closed vessel and at a temperature above 75 DEG  C. but below the boiling-point of water at the pressure employed, with an aqueous solution of an alkali metal or ammonium carbonate in an amount at least corresponding to the saponification value of the oxidation product, and preferably in excess thereof, the resulting salts being acidified to obtain the free fatty acids after removable of the unsaponifiable constituents.  The alkali carbonate can be employed in the form of from a 5 per cent aqueous solution to a hot saturated solution, and is preferably employed as a 20 per cent solution, the product to be saponified being slowly introduced into the hot solution of carbonate.  At the commencement of the treatment the temperature is kept between 60 and 100 DEG  C., preferably between 80 and 95 DEG  C., until the greater part of the carbon dioxide has been evolved.  Towards the end of the reaction the temperature is preferably raised about 100 DEG  C., up to, for example, 160-185 DEG C., or even up to 350 DEG  C., the pressure being increased to 8 to 9, or even 15 or more atmospheres.  The reaction mass is preferably kept mixed, for example, by means of turbo-stirrers.  The saponification may be carried out continuously in a turbo-mixer, either with direct flow throughout, or carrying out the second part of the saponification in a cycle.  When the saponification is complete the upper layer comprising unsaponifiable products which separates, if necessary after dilution with water, is removed. Any remaining unsaponifiable constituents may be extracted with organic solvents such as gasoline, carbon tetrachloride, other chlorinated hydrocarbons, or ethyl ether.  The unsaponifiable constituents may be subjected to oxidation again, if necessary after washing with water or dilute alkali carbonate solution. Examples are given.

Title: Improvements in and relating to electro magnetic switches
IPC: H01H9/44
Filed: 1921-04-12
Abstract: 182,923. British Thomson - Houston Co., Ltd., (General Electric Co.). April 12, 1921. Electromagnetic switches; magnetic blow-outs. - Electromagnetic switches are provided with a blow-out device associated with the iron structure in such a manner that a portion of the magnetic flux is shunted so as to dis rupt the arc. An electromagnetic series lock-out switch having a shunt-closing magnet 32 and a series holding-out magnet 31 is illustrated. The shunt magnet 32 has a core 33 clamped between fixed upper and lower magnetic plates 26, 24 respectively. The contact 14 is resiliently mounted on a bell-crank lever 11 pivoted at 12, the lower arm of the lever 11 being pivotally connected at 18 to a plunger 19 passing through the series coil 31. The lower end 21 of the plunger 19 is of reduced section and is surrounded by a relatively fixed adjustable magnetic sleeve 22. A closing air gap 25 is provided between the enlarged upper end of the plunger 19 and the plate 26, and an adjustable holding-open air gap between the upper end of the core 19 and the magnetic sleeve 22.

Title: Warping on section warping beams
IPC: D02J1/00
Filed: 1977-03-15
Abstract: In order to prevent loops and fluff from being pushed on during the processing of non-twisted or only slightly twisted threads, the individual filaments of a thread lying next to one another are swirled by means of compressed air and are thus interlaced at more or less large intervals. If this process is carried out simultaneously with the spinning or drawing process, only large interlacing intervals can be achieved because of the high thread speed. Here, the swirling is carried out simultaneously for all the threads, after the conclusion of the thread-producing process, in the course of the warping operation which takes place relatively slowly. The threads are thus drawn from a bobbin creel (15) via breaks, thread-guide members (16), an eyelet reed (17), a fluff monitor (20), an oiling device (21) and a thread store (22) and are wound onto part warp beams (24). The swirling device (18) is preferably installed between the eyelet reed and the fluff monitor. The swirl nozzles (9) are arranged close to one another in a common housing (1, 3) and are provided with a common air-supply system. The swirling process is controlled via a regulating valve and a three-way valve (4). <IMAGE>
