Abstract: 428,753. Controlling variable speed gearing. HAZSLINSZKY, L. VON, and LUKACS, G. VON, 19, Dregely U., and LANG, J., 36, Kelenhegyi Ut, both in Budapest. Sept. 12, 1934, No. 26217. Convention date, Sept. 13, 1933. [Class 80 (ii)] In change-speed gear for motor vehicles, a pivoted and longitudinally - movable catch 25, Figs. 1 and 4, is rocked into engagement with one of the selector bars 30, 31, 32 by a stepped cam 29 turned by a centrifugal governor 16 driven from the engine. The catch is shifted longitudinally by a rod 23 reciprocated by a crank disc 18 which is caused to turn through half a rotation each time a gear-change is made. The governor 16 acts through a pivoted lever 50, rods 51, 52, toothed discs 3, 4, and links 34, 35, 36 on the cam 29. The disc 3 carries the starting handle 1. For each gear step a projection 6 on the disc 4 tilts a trip lever 5 to release a lever 7, thus permitting a clutch 10, 12 to engage so that disc 18 is rotated half a turn from the engine-driven shaft 15 of the governor 16. One of two pins 42 on a disc 20 fixed to the disc 18 then engages a lever 45 to bring a partly toothed wheel 43 into engagement with teeth on the disc 20. The wheel 43 carries a cam 46, which with the assistance of a spring forces the lever 7 back to its full line position. During this gear-shifting movement, the main vehicle clutch pedal 37 is automatically depressed by 2 : 1 gearing 21, 38 and connecting- rod 40 operated from the disc 18, the clutch being permitted to re-engage under the action of a dashpot. As the accelerator pedal 48 is depressed, the pivot 53 of the lever 50 is shifted through links 55, 56 and worm gearing 54, thus altering the engine speeds at which the governor 16 effects the gear-changes.

Title: Improvements in the manufacture of steel files
IPC: B23D73/00
Filed: 1919-10-27
Abstract: 159,254. Strickland, F. Oct. 27, 1919. Screwing; dics.-In making round steel files by cutting multiple screw-threads on a round bar. then forming the tang and finally hardening and tempering, the threads are cut by the successive action of two or more cutting tools, dies or chasers which are angularly displaced with relation to each other and have their teeth so dispcsed axially that one chaser &c. cuts the two sides and bottom of one helical groove and another the two sides and bottom of an adjacent groove so as to form between the grooves distinct screw threads, the two sides of which are cut at different times to ensure a sharp cutting edge. When two chasers are used the pitch of the teeth on each chaser is double the pitch between the grooves. The chasers are arranged so that the side of one thread not cut by one chaser is cut bv the next. When a double thread is formed, diametrically opposite chasers A, B, Fig. 2, are provided respectively with teeth 1, 2 for cutting adjacent helical grooves b, c so that the two sides of each portion of the intervening thread are cut at different times, the side of the thread not cut by the teeth 1 being cut by the teeth 2 and vice-versa., the bottom of the grooves being rounded. Triple or quadruple threads may be formed respectively by three or four chasers. Four chasers may also be used to produce a double thread, a pair of chasers diametrically mounted in a die head for one thread being arranged at right-angles to a second pair similarly mounted for the second thread. The threads may be cut in an automatic machine in which an intermittently-fed length of rod is acted on by the dies, which are mounted on a turret. The die-head advances during cutting and is withdrawn when the thread is completed, whereupon a cutting.head severs off a length sufficient to leave an unthreaded portion to form the tang.

Abstract: 1503007 Treatment of pitch; carbonization; graphitization KUREHA KAGAKU KOGYO KK 20 June 1975 [24 June 1974] 26400/75 Heading C1A [Also in Division C5] Crystalloidal pitch is produced by (1) treating solid pitch particles having a maximum dimension of the minimum projected area of not more than 5 mm. to render them resistant to mutual fusion and then (2) contacting the particles with a non- oxidative gas at 350-550‹ C. while maintaining a void ratio of not less than 30% by volume. The treatment (1) can be carried out by (a) coating the particles with a metal (e.g. Cu, Cr, Ni or Ag), or a metal salt (e.g. a chloride of Ni, Fe or Al) or with a phenol, furan or epoxy resin; (b) forming an oxidized coat on the particles by immersing the particles in a solution of hydrogen peroxide, a chlorate, a hypochlorite, a perchlorate, nitric acid, ferric chloride, a dichromate, a mixed acid, a permanganate or a peracetate or by treating the particles with an oxidizing gas (e.g. oxygen, ozone, an oxide of sulphur or nitrogen or a halogen) which can be diluted with an inert gas (e.g. nitrogen, argon, hydrogen, steam or combustion gas) or (c) removing low boiling point or low melting point components by extracting the particles with a solvent such as acetone, methylethyl ketone, benzene, toluene, hexane, heptane, cyclohexane, methanol, chloroform or carbon tetrachloride. The softening point of the particles treated by extraction can be increased by heating between the softening and flow points of the pitch. The particles can be globular, filamentary or other shapes and can be composed of petroleum pitch, coal pitch (optionally containing 3 wt. per cent iron chloride) or pitch derived from by-product tars produced by thermal cracking of crude oil or naphtha. The heating can be carried out in a fluidized bed, fixed bed or rotary kiln. The crystalloidal pitch can be carbonized and graphitized, e.g. by heating in argon at up to 2400‹ C.

Abstract: 1488556 Removing organic compounds from gases BAYER AG 24 June 1975 [27 July 1974] 26719/75 Heading ClA Organic compounds are removed from a gas by combustion in the presence of a catalyst which contains metal selected from Co, Ni, Ru, Rh, Pd, Os, Ir or Pt carried on a support which is composed at least partly of lithium aluminium spinel. The support preferably contains more than 50% by weight of said spinel and the metal is present in amounts of 0À01-2% by weight. The gas may contain 0À01-10% by weight of organic compounds. The spinel may be made by impregnating Al 2 O 3  of high surface area with an aqueous lithium salt solution, e.g. LiOH, drying the impregnated supports and converting the salts to oxides by heating to 250-650‹ C., if appropriate in the presence of O- or H- containing gases. The material may then be heated to 900-1, 300‹ C. for a period of 1-10 hours to cause the spinel to form. The surface area and pore diameter of the spinel may be varied by changes in the calcination temperature and duration. The catalyst may be made by applying a salt of the metal to the thus formed spinel and precipitating the metal by reduction, e,g. with hydrazine hydrate.
