Title: Improvements in the recovery of oxidation products of solid hydrocarbons, waxes and the like
IPC: C07C51/42
Filed: 1927-11-07
Abstract: 309,875. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 7, 1927. Sizes and finishes. - Alcohols, aldehydes, ketones, acids, and other products of the oxidation of solid hydrocarbons are removed from unoxidized, raw material by mechanical pressure at a temperature below its melting point. In an example, crude, oxydized paraffin wax containing 50 per cent of acids is submitted in press cloths to hydraulic pressure of 50 atmospheres at 15‹C. The 30 per cent residue contains 95 per cent of paraffin wax; the 70 per cent pale oil expressed may be used for the preparation of soaps, emulsifying agents, sulphonated oils, and the like, and may be used for oiling or smoothing in the textile industry. In a modification the crude oxidatiom product is first neutralized with aqueous alkali, allowed to stand and cool to separate the soap solution, and then pressed. The expressed liquid is mainly high-molecular alcohols. Specifications 183,186, [Class 91, Oils &c.], and 287,514 are referred to.

Title: Improvements in friction clutches
IPC: F16D43/12
Filed: 1933-10-31
Abstract: 427,649. Friction clutches. GILLETT, E. H. J. C., 32, Marlborough Mansions, Cannon Hill, Kilburn, London. Oct. 31, 1933, No. 30216. [Class 80 (ii)] In a friction clutch comprising a driven plate 17, Fig. 1, interposed between a driving flywheel 11 and a presser plate 12, the latter is urged towards the plate 17 by engaging springs 19 and is adapted to be retracted under all conditions through radial levers (not shown) upon movement to the left of a sleeve 28 by depression of a clutch pedal 42, and a spider 32 is urged to the right, to coact with abutment nuts 39 on studs 38 secured to the plate 12, by disengaging springs 23 which are stronger than the springs 19, and is urged to the left by the centrifugal action of weights 35 pivotally mounted in circumferential slots 48 in the flywheel. Outward movement of the weights is limited by a ring 49. At low speeds, the clutch is disengaged, but as the speed increases the centrifugal effect of the weights moves the spider to the left, comprising the springs 23, until eventually the clutch is engaged with the full force of the springs 19. By operating a lever 43 through Bowden mechanism 45, the spider may be manually moved to the left so as to render the centrifugal control ineffective. As shown in Fig. 4, a lever 43, 56 controlling the spider 32 is loosely mounted on the pedal shaft 55, while a lever 40, 52 controlling the sleeve 28 is loosely mounted on a shaft 51. The arm 52 carries a roller 53 coacting with a cam 54 secured on the shaft 55. On depressing the pedal 42, the radial face 54<a> of the cam coacts with the arm 52 to move the sleeve 28 to the left, disengaging the clutch. Upon overdepression of the pedal, the roller 53 rides on to the circular portion 54b of the cam, maintaining the clutch disengaged, and the face 54<a> coacts with the arm 56 to move the spider 32 to the left to render the centrifugal control ineffective. Return movement of the spider, upon release of the pedal, is adapted to be prevented by a pawl 57 which is loosely mounted on the shaft 51 and which is connected by a spring 59 to an arm 58 connected to Bowden mechanism 45. The latter may thus be operated preselectively, the selected movement of the pawl taking place upon over-depression of the pedal 42. The disengaging springs may, alternatively, be external to the clutch, and the centrifugal weights may be mounted on an auxiliary engine-driven shaft.

Title: Improvements in or relating to the manufacture of optical glass
IPC: C03B25/02
Filed: 1936-11-06
Abstract: 484,587. Glass manufacture. SENDLINGER OPTISCHE GLASWERKE GES. Nov. 6, 1936, No. 30311. Convention date, Nov. 7, 1935. [Class 56] Relates to a method of obtaining the contents of a pot of optical glass in the form of a large block instead of irregular pieces. According to the invention, the pot of homogenized glass, after removal from the furnace, has the bottom and sides cooled rapidly while the cooling of the surface of the glass is retarded in such a manner that solidification of the glass takes place from the sides and bottom of the pot. This is effected by placing a heating-plate, or a pre-heated insulating plate over the surface of the glass. When the temperature of the side and bottom layers of glass has reached the lower annealing temperature, the hotter middle portion is allowed to cool and the whole pot is then placed in an electricallyheated chamber and kept at the lower annealing temperature until the temperature within the block of glass is equalized. After further cooling, the block of glass is divided into pieces of definite size free from striae by any suitable means, such as by passing slowly through the glass a platinum wire heated to incandescence.
