Title: Slide valves
Inventor: FLINT JOHN CHRISTOPHER EGLINGT
IPC: F15B13/08
Filed: 1965-03-03
Abstract: 1,130,162. Valves. DOWTY HYDRAULIC UNITS Ltd. 19 Nov., 1965 [3 March, 1965; 23 April, 1965 (2)], Nos. 9076/65, 17163/65 and 17164/65. Heading F2V. In a parallel slide valve, the slider 20 has a main port 38 which is in permanent communication with the pressure supply port 27, Figs. 3 and 6 (not shown). There is at least one service port in the housing, which aligns with a balance port in the slider, e.g. the port 45, in a neutral position as shown. By movement in either direction, the service port is placed in communication alternatively with the supply port 38 or with an exhaust chamber 21 by an end control edge 47 of the slider. In the embodiment a second balance port 46 corresponds to a second service port, for controlling a double-acting jack S 1 , Fig. 5 (not shown). The valve is centred by a spring device 25 and operated manually by a lever 23. Two such valves for controlling separate jacks are incorporated in a unitary casing comprising spaced slider frames 13, 15 assembled with casing members 12, 14, 16. With both valves in neutral, the supply inlet 27 is in direct communication with the exhaust outlet 28 through an unloader port 49 in each slider and passages 52, 53, 54 in the casing members. The supplies to the valve chambers go through individual check valves 39, 40. A two-stage type relief valve 35 relieves pressure directly from a common pressure passage 34 to the exhaust outlet 28. Inching slots 55 to 60 are provided respectively at the two ends of the pressure port 38, at the two ends of the unloader port 49, and at the opposite end control edges 47, 48 of the slider in line with ports 38, 45, and 46. Two balance ports 50, 51 are provided on either side of the unloader port 49. In modifications, Figs. 7-11 (not shown), the arrangement of the inching slots is varied to cater for different requirements as to precision of control.

At the bottom of bins 3 and 5 the moulds are taken away on conveyers 16b to a point opposite transverse roller conveyers 16c, where they are emptied and transferred to conveyers 16 and filled again. Each bin comprises guide rails 6 and a coil 7 through which flows warm water or steam which heats the air to 30- 60‹C. The warm air is circulated by fans 10. Stairs 14 and a control bridge 15 are provided. Each mould comprises side walls 17 and a removable base 18 supported on cross-bars 19, and a cover made of a sheet 20 supported by bars 21 fixed to cross-bars 22.

Title: Acetals
IPC: C08B31/18
Filed: 1963-03-07
Abstract: Acetals are made by reacting one mole of a dialdehyde polysaccharide with at least 2 moles of a dialkyl sulphoxide at 40-100 DEG  C., and treating the adduct with at least 5 moles of an aliphatic or araliphatic saturated or unsaturated primary, secondary, or tertiary alcohol or a polyalcohol in presence of an acid catalyst in an anhydrous medium at 40-100 DEG  C. for 2 to 10 hours.  Specified sulphoxides are dimethyl and diethyl sulphoxides, while the alcohol may be methanol and the catalyst may be HCl, H2SO4 or a toluene sulphonic acid.  The acetals, obtained in powder form, may be formed into films by dissolving in, e.g. dioxane and casting.

Filed: 1955-03-31
Abstract: 766,115. Making shafts. EATON AXLES, Ltd. March 31, 1955 [April 13, 1954], No. 9393/55. Class 83 (2). A method of manufacturing shafts comprises the consecutive steps of forging an asrolled bar to basic shaft shape, next quenching the heated forged shaft and tempering it to predetermined core hardness, then machining the shaft to substantially finished form and size, induction hardening the shaft to predetermined surface hardness, and then quenching and tempering the shaft to draw back the surface hardness to a predetermined amount. An as-rolled alloy steel bar is forged to shape 10 with an annular flange 16 at one end and an enlarged cylindrical portion 18 at the other end. The form 10 is then quenched in oil, after heating to 1500-1550‹ F., until the form reaches a temperature of 325-350‹ F. when the form is removed and tempered all over at 1100-1200‹ F. for 1¢ hours to a core hardness of 275-321 Brinell. The form 10 is then, if necessary, straightened, cut off and centred. The flange 16 is then machined to shape, Fig. 3, and the portion 18 machined to provide splines 22. Defects are removed by belt grinding the shaft. The shaft is then induction hardened to provide a surface hardness of 59-64 Rockwell C and, immediately after, oil-quenched and tempered at 400-600‹ F. to a surface hardness of 52-57 Rockwell C. A final straightening and shot peening is then effected if necessary and a final machining to provide, for example, shaft puller holes 24 is also effected.

Abstract: 1452279 Treating gases; aluminates IMPERIAL CHEMICAL INDUSTRIES Ltd 5 Feb 1974 [27 Feb 1973] 9474/73 Heading C1A [Also in Division C5] In a process for the removal of acidic impurities from a process fluid which is to be treated over a solid catalytic material and/or a hydrogen sulphide absorbing material, the fluid is contacted with one or more alkali metal aluminates, the aluminate being present as discrete pieces distinct from discrete pieces containing catalytic material and/or hydrogen sulphide absorbing material, and being disposed so as prevent access of strongly acidic impurities in the fluid to the catalyst and/or hydrogen sulphide absorbent. The aluminate may be supported on alumina or other refractory oxide, and may be present as a bed separate from that containing the catalyst and/or hydrogen sulphide absorbent, or may be mixed therewith. In examples, N 2 -and H 2 -containing streams are freed from HCl and organic chlorine compound respectively. The aluminate may be made by reacting an alkali metal compound (oxide, peroxide, hydroxide, carbonate, nitrate, nitrile or salt of carboxylic acid) with alumina or by applying either a mixture of aluminate forming compounds or the aluminate to a support material which is itself preferably alumina. In the first case, the alumina which is reacted with the alkali metal compound preferably has a specific surface of greater than 100 m<SP>2</SP>/g and pore volume greater than 0À3 cc/g. The aluminate thus formed after reaction at less than 500 C. has a specific surface of 5-90 m<SP>2</SP>/g and pore volume 0À3-0À6 cc/g. The aluminate is preferably in the beta form, and the examples describe production of gamma sodium aluminate, beta sodium aluminate, and sodium beta alumina.
