Title: Improved means for stopping colliery tubs on inclines and for similar purposes
IPC: B61K7/16
Filed: 1920-05-19
Abstract: 167,611. Hopkins, G. T. May 19, 1920. Arresting-grips on permanent way. - Apparatus for stopping colliery tubs on inclines and for similar purposes comprises braking-bars a supported by parallel links c in a position parallel to the rails such that they engage the upper part of the wheels. The bars a are connected across the rails by a bar e bent upwards at each end. When the links c are in a position at right-angles to the track, the bars a are clear of the wheels of a vehicle, but when inclined in the direction of motion produce a wedging action. The position of the bars is adjusted against the action of gravity by a tension member g operated by a lever f. The tension member may have a spring m therein arranged so as to be capable of limited extension. The links c being moved into an upwardly inclined position a limited braking effect is produced, the bars a then not being capable of movement into the wedging position. A spring control of the links c is employed when the track is level.

Title: Improvements in or relating to the spinning of artificial silk or the like
IPC: D01D7/00
Filed: 1928-05-11
Abstract: 317,125. Healey, C. J. May 11, 1928. Winding-machines; reeling-machines; skein holders and swifts; thread-guides; rollers; spindle apparatus.-In spinning artificial silk or the like, precipitated thread produced by the cupra-ammonium, viscose, or other process is wound on to cylinders with a suitable crossing and at even tension by causing it to be drawn through a pair of forks or like guides so arranged and reciprocated that the line between them is inclined at a substantially constant obtuse angle to the draw of the cylinder; a similar arrangement is adopted for centrifugal spinning in relation to the godets or draw-off rollers, the reciprocation of the guides then serving to prevent grooving of the rollers. The winding-cylinders are arranged in two or more tiers, consecutive jets supplying cylinders in alternate or successive tiers, and when the invention is applied to centrifugal machines the pots or boxes are similarly arranged. Forks or guides Q<1>, R<1>, Q<2>, R<2> are mounted on reciprocating shafts 0, P, or each of a pair is independently mounted, adjacent to the cylinder or bobbins G<1>, G<2> and the filaments are thereby maintained at a constant obtuse angle to the bobbins during the traverse as shown in Fig. 2. In each tier the bobbins are mounted in pairs and the filament is directed from a fully wound bobbin to an adjacent empty bobbin, as shown in dotted lines in Fig. 2, when required. The shaft of each bobbin carries a friction driving-wheel K, and at the end remote therefrom is mounted in open bearings N to facilitate removal. The bobbins are of large diameter and small width, say one foot in diameter and four inches wide, and are carried by a swift comprising fixed arms a, Fig. 3, and pivoted arms b, which are provided with rubber pads e to engage the bobbin and are movable against a spring by a sliding hub g to permit of the removal of the bobbin. The filament may be passed through an auxiliary bath B. The spinning-jets project into auxiliary troughs D<1> as described in Specification 317,126, [Class 2 (ii), Cellulose &c.].

Patent GB-809118-A (GB)
Title: Improved process for the preparation of aromatic aldehydecarboxylic acids
Filed: 1956-05-07
Abstract: Aromatic aldehyde-carboxylic acids are prepared by oxidizing a chloromethylated-aromatic carboxylic acid with nitric acid.  The reaction takes place in two steps.  The chlorine of the chloromethylated-carboxylic acid is hydrolized with water, and the product of the hydrolysis partially or wholly separated from the reaction mass, and then oxidized with dilute nitric acid, preferably having a concentration of 10 to 40 per cent.  The hydrolysis with water is preferably carried out in the presence of a substance capable of neutralizing the acids formed during the hydrolysis, e.g. calcium carbonate.  The amount of water present should preferably be from two to eight times the weight of the product to be hydrolysed and the amount of calcium carbonate preferably smaller than that equivalent to the amount of acid formed in the hydrolysis.  The hydrolysis may also be carried out with alcohols or other organic solvents in the presence or absence of metallic salts or organic compounds such as sodium acetate, the ethers or esters so formed may then be oxidized to aldehydes. The hydrolysed product is separated, either hot as an oily substance or cold by filtering it from water. Examples are given of the preparation of meta- and para-aldehyde benzoic acid.

Title: Improvements in or relating to the preparation of ozonides

Filed: 1939-05-12
Abstract: 532,104. Olefine ozonides ; polystyrene. STANDARD TELEPHONES & CABLES, Ltd., and WARNER, A. J. May 12, 1939, No. 14233. [Class 2 (iii)] Ozonides of amylene and higher olefines are prepared by passing ozonized oxygen into the olefine at a temperature of -20‹ to -30<SP>0</SP>C. In the case of viscous olefines, a solvent is employed which is subsequently evaporated away. According to the examples, (1) ciiisobutylene, a mixture of 2:4:4-trimethyl-1-pentene and 2:4:4-trimethyl-2-pentene, prepared by dehydrating tertiary butyl alcohol with concentrated sulphuric acid, is placed in a vessel which is surrounded with solid carbon dioxide and ozonized oxygen is passed through a sintered glass plate immersed in the liquid olefine; when the liquid becomes viscous, the temperature is allowed to rise to -5‹C. and the ozonolysis carried to completion; (2) diamylene, which is a by-product of the chlorination of mixed pentanes and consists of 3:5:5-trimethylheptene-2 and 3:4:5:5-tetramethylhexene-2, is dissolved in dry hexane and ozonized oxygen is passed through the solution in a vessel surrounded with solid carbon dioxide ; the hexane is evaporated from the product by means of a vacuum pump ; amylene ozonide may be prepared in a similar manner. A mixture of styrene with any of the ozonides in the proportions used for accelerating its polymerization is stable for some days at a temperature of 0‹-5‹C.

Title: Cage forming and cage loading mechanism for oil presses

Filed: 1921-05-31
Abstract: 164,015. Murray Co., (Assignees of Henry, N. B.). June 1, 1920, [Convention date]. Fatty oils, extracting by pressure. Oil seeds &c. are received from the discharge opening of a cooker into cavities formed in a rotating plate which carries them by a step-by-step movement into position to be delivered to the cage of an oil-press. The motion is interrupted to allow plates and cloths to be placed above and below the charges of seed &c. to separate the cakes. The plate 3 with the openings 4, 4<a>, 4<b>, 4<c> rotates between a plate 12 fixed below the mouth of the cooker and a table 6 having an opening in its edge into which can be fitted an oil-press cage 40 running on wheels 46. The plate 3 is formed with slots 41 with which engages a roller 10 mounted on a rotating ring 11. The cakes are forced into the cage 40 by a 'hydraulic plunger 32 against the action of a plunger 43 in a cylinder 42 from which liquid can escape through a loaded valve 461. The plunger 32 can be raised by a second plunger 313 and the admission of liquid to the cylinders containing the two plungers is controlled by a valve which is interlocked with the disc 31 and the gear driving the ring 11. For this purpose the valve is operated by a lever 34 carrying a roller 36 engaging with notches 38 in the edge of the plate 3 so that the plunger 32 can only be lowered when one of the openings 4, 4<a>, 4<b>, 4<c> is in position to receive it. At the same time a wedge on the end of a rod 23 attached to the lever 34 allows an arm 25 to fall into the path of the roller 10, which strikes against it, thereby operating a clutch to disengage the driving-gear of the ring 11.
