Abstract: 252,933. Buckton & Co., Ltd., J., and Watson, F. L. July 29, 1925. Lathes.-A lathe for turning railway vehicle axles and the like has a central driving headstock on each side of which a tool saddle B provided with front and back tool rests A', A<2> is mounted. The tool rests are adjusted simultaneously to and from the work by a hollow right and left hand spindle C actuated by a hand wheel E and independent adjustment of the rear tool rest is effected by a spindle F passing through the spindle C and connected by spur gears G to a spindle H which moves the rear tool rest on a supplementary slide J.
Patent GB-292790-A (GB)
Title: Improvements in devices for producing motion of a body by a fluid jet impinging thereon
IPC: H02M1/30
Filed: 1927-07-21
Abstract: 292,790. Hartmann, J. F. G. P. July 21, 1927. Gas-explosion signals.- Relates to devices in which the momentum of a fluid jet is used to impart motion to a body, the invention residing in the use of controlling means for periodically cutting the jet or deflecting it as a whole therefore interrupting or varying its dynamic impinging action on the body. In Fig. 3, a jet J issuing from a nozzle N impinges on a disc B which is pivoted at O and carries an arm A and screen S. The jet acts to press the disc backwards and raise the screen to sewer the jet, but the screen is so shaped as to facilitate its return when the pressure on the disc has disappeared, a spring aiding this return if desired. The system SAB acts as an oscillatory system to the natural period of which the periodical impulses of the jet may be tuned either by adjusting the velocity of the jet or the length of the arm A. Such a device is a periodic interrupter in a circuit a, c, d, but it may be modified for an acoustic generator by producing a spark at c in an inductive circuit, an explosion resulting if a hydrogen jet is used, or a jet of explosive mixture. Alternatively, the disc B may be an elastic membrane which, when pressed back, interposes a screen in the path of the jet. Alternatively such an elastic disc may carry a contact which closes a circuit to actuate the screen electromagnetically. Alternatively the membrane may act to drive an air wave with the velocity of sound into a tube, thereby causing a further membrane to actuate the screen. Fig. 11 shows such a membrane used with a fixed screen and a jet which is traversed by a direct current. An electromagnet F is arranged to deflect the jet against the screen so breaking the circuit periodically. Fig, 12 shows an arrangement in which the motion of the body is controlled independentdy of the motion, the screen S being secured to a string in a constant magnetic field F and caused to vibrate when traversed by current from an A.C. transformer. If the impulses are tuned to the period of the membrane B (or to a cylindrical resonator, Fig. 13, not shown) the device represents a source of sound. In another form the screen comprises an aperlured disc rotated by an A.C. synchronous motor, whereas in yet another form, deflection of the jet is produced bv interaction between direct current traversing it and an A.C. field, a fixed screen intercepting the jet.

Title: Improvements in or relating to the application of a substance to a moving length of material
Inventor: VINCENT JOHN JOSEPH
IPC: D06B23/28
Filed: 1953-07-16
Abstract: In applying to a continuously-moving length of material, e.g., warp, a prescribed weight per unit length of a substance, a stock liquor containing the latter is fed from a container to a bath at a rate predetermined by the speed of the material and by the said prescribed weight of the substance per unit length, any change in the weight of liquor in the bath, resulting from a deviation of the actual rate of application from the prescribed rate, being utilized to alter some property of the liquor in the bath so as to correct the deviation. The stock liquor comprises one or more ingredients dispersed in a cold liquid such as water.  At least one ingredient, e.g., starch, is ungelatinized at this stage, but becomes gelatinised when the liquor is heated in the bath before being applied to the material.  One or more of the ingredients, e.g., carob bean flour, is capable, without changing the nature of the others, of imparting sufficient viscosity to the liquor to maintain, at least in the cold stock liquor, a homogeneous dispersion of the substance.  The dry powdered ingredients may be mixed together and then with cold water to furnish the stock liquor.  In order accurately to obtain a desired concentration of the substance in the stock liquor, a packaged quantity of an air-dry mixture of the ingredients containing a known oven-dry weight of the substance is mixed with water to furnish a selected overall weight or volume of stock liquor.  One of the ingredients may be clay.  A suitable stock liquor or size contains 100 parts of sago starch, 4 parts of carob-bean flour, 8 parts of tallow and 400 parts of water, all parts being by weight. Specification 654,178 [Group VIII] is referred to.

Title: Improvements in processes for vulcanising rubber and products thereof
IPC: C08K5/00
Filed: 1935-07-12
Abstract: The reaction product of a furoyl halide and a mercapto-arylene thiazole is used as an accelerator of vulcanization for rubber. The product is prepared by the addition of the furoyl halide, preferably the chloride to an alkaline solution of the mercaptoarylene thiazole, preferably mercaptobenzothiazole.  The corresponding furoyl bromide or iodide may, however, be used. The furoyl group may contain one or more alkyl or substituted alkyl substituents and the arylene radial of the mercaptoarylenethiazole may also carry alkyl substituents.  In an example, furoyl chloride is added to an alkaline solution of mercaptobenzothiazole and the precipitated furoyl benzothiazole sulphide filtered off.ALSO:The vulcanization of rubber is accelerated by the addition to the mix of the reaction product of a mercaptoarylene thiazole and a furoyl halide.  The reaction products may be used alone or in conjunction with an amine type of activator. Such activators are amides, imides and organic salts of amines, such as for example the salts of diphenyl guanidine with phthalic acid, formic acid, acetic acid and tartaric acid.  The new accelerators are preferably produced by first forming a sodium salt of the mercaptoarylene thiazole, and then reacting this with furoyl chloride.  The corresponding bromide or iodide may be used but the chloride is preferred.  In the case of mercaptobenzothiazole the product has the formula <FORM:0455564/V/1> The furoyl group may contain one or more alkyl or substituted alkyl substituents, and the arylene radical of the mercaptoarylenethiazole may also carry alkyl substituents.  The term rubber includes caoutchouc and similar vulcanizable materials such as guttapercha and balata.  It is stated that the accelerators of the present invention are of outstanding stability and substantially nondiscolouring when used in light coloured stocks.  In an example furoyl chloride is added to an alkaline solution of mercaptobenzothiazole and the precipitate of furoyl benzothiazole sulphide filtered, and washed.  Specification 346,853 is referred to.
