Title: Improvements in and relating to hydraulic jacks
IPC: B66F3/30
Filed: 1946-01-11
Abstract: 620,399. Hydraulic Jacks. BEARD, S. W. G., and ROTOL, Ltd. Jan. 11, 1946, No. 1116. [Class 69 (ii)] [Also in Group XXXIII] In a hydraulic jack with provision for locking the relatively movable parts against movement beyond a predetermined intermediate position in the stroke, a stop, resiliently mounted on one part, is adjustable transversely into or out from the path of the other part ; the stop is normally held in said path so as to limit the stroke of the jack, but is released to permit the full stroke, by applying fluid at a higher than normal pressure to the jack. The invention is applicable to jacks for pitch adjustment of airscrews where a higher-thannormal pressure is applied to move the blades beyond fine pitch into reverse. Thus, in Fig. 1 (Comp.), a piston 7, connected with the blades by links 8 and working in a cylinder 6 rigid with the airscrew boss, has an extension sleeve 10 working over an annular guide 9. At the end of guide 9 are abutments 12 which the end of sleeve 10 normally engages to limit movement of the piston 7 when pressure is applied on its right to move the blades to fine pitch. The abutments 12 are formed on radiallyresilient tongues on a fixed sleeve 11, and are held in their normal projected position by a ring 19 on an axially-movable plug 14. Spaced piston parts of plug 14 work on a fixed sleeve 15 and co-operate with stationary pistons 20 to form pressure spaces 21. These pressure spaces are normally open to the-left of piston 7 through passages 23, 22 and an opening 25 in a piston valve 26, the hollow interior of which is open to the left of piston 7. The operating fluid applied to the right of piston 7 is also applied by a passage 35 to the piston valve 26 and, if higher-than-normal, moves the valve against its spring 27 so that fluid is admitted through passages 25, 22 and 23 to the pressure spaces 21. The plug 14 is thereby moved to the right and disengages the abutments 12 so that the sleeve 10 can ride over them, and allow the piston 7 to move its full stroke into reverse pitch. The normal fluid pressure cannot move the piston valve 26 against its spring so that plug 14 remains stationary with the abutments 12 projected to limit the stroke of piston 7. In a modification, Fig. 2 (not shown), a single piston operating the plug 14 works in a cylinder formed in a forward extension of the main cylinder 6. In the form described in the Provisional Specification, the resilient abutments 8 are secured to the front 7 of the main cylinder and the plug 10, normally maintaining them projected, is formed as a piston to which pressure is applied by way of non-return valves 15 and 16. Pressure applied to the main piston 2 is also applied by a passage 17 to the space between valves 15, 16 and, if higher-than-normal, unseats valve 16 and actuates the plug 10 to release the abutments 8 and so permit a full-stroke of the main piston. Specification 509,299, [Group XXXIII], is referred to.

Title: Preparation of fluorinated organic compounds
IPC: C07C17/23
Filed: 1953-01-14
Abstract: Dichloro difluoro methane is converted into other fluorinated hydrocarbons by heating a mixture of the vapours of dichlorodifluoro methane and a saturated aliphatic hydrocarbon containing 1 to 4 carbon atoms at a temperature from about 400 DEG  C. to about 1000 DEG  C.  Reaction is preferably effected in the presence of a metallic catalyst containing copper or platinum including pure platinum and its alloys with rhodium, palladium or iridium; copper-chromium oxides, cobalt oxides, nickel oxides and other hydrogenation catalysts may also be used; the process is operable, however, in the absence of a catalyst.  Examples describe the reaction of CCl2F2 with methane in a quartz tube heated to various temperatures from 650 DEG  to 810 DEG  C., with contact times varying from 2.7 to 6.4 seconds, using in some cases platinum-rhodium gauze or copper turnings in the tube.  The products obtained comprise CHClF2 and CH2= CF2 and various of the following: CF3Cl, CF2=CF2, CH2F2 and CH2=CHF.  Ethane, propane and butane may replace the methane, longer chain fluoro compounds then being formed.

Title: Manufacture of hexitols or mixtures of isomeric hexitols by the catalytic reduction of carbohydrates
IPC: C07C31/26
Filed: 1947-01-17
Abstract: Commercial glucose or similar mixture of glucose with maltose and/or dextrins is catalytically reduced in the liquid phase to hexitols by continuous passage, with the catalyst in suspension therein and with hydrogen, at elevated temperature and pressure, through a reaction zone in which the temperature is raised continuously or in stages from the inlet to the outlet end. Products of starch hydrolysis such as commercial glucose have the glucose content reduced at the low initial temperature, while the polysaccharides are only substantially reduced in the hotter portion of the reaction zone.  A single tube-shaped reactor may be used or a plurality of reactors at different temperatures and pressures.  Recycling of the reaction mixture or of the hydrogen may be effected.  An acid catalyst may be added to the reactants to hydrolyse the polysaccharides.  Hydrogen may be supplied through fine filters or partitions provided.  The catalyst may be added as a pre-formed suspension or paste in the initial mixture or product.  In an example, a 50 per cent aqueous solution of commercial glucose in which is suspended a nickel-diatomaceous earth catalyst is hydrogenated by passage through a tube at 100 atm. and a temperature rising from 140 DEG  to 200 DEG C. from inlet to outlet to give sorbitol.
