Title: Level-Regulating Hydro-Pneumatic Suspension Unit, Particularly for Motor Vehicles
IPC: B60G17/04
Filed: 1968-02-13
Abstract: 1,188,453. Self-levelling suspension units. HOESCH A.G. 13 Feb., 1968 [14 Feb., 1967], No. 6979/68. Heading F2S. In a self-levelling hydropneumatic pistoncylinder suspension unit having two valvecontrolled channels by which one end of the cylinder can communicate through the piston with the other end of the cylinder, only one of the channels can be open at any one time and only one direction of flow is possible in each channel. The direction of flow is always such as to return the piston to a central position. In Fig. 1 the chambers 5 and 6 on opposite sides of the piston 2 are each filled with liquid maintained under pressure by respective gas chambers 15. The piston and its rod 3 are hollow and are fitted over a solid rod 4 in one end of the cylinder body. The throughpiston flow paths are: (a) groove 17 in rod 3, bore 24 in piston 2, valve 22; and (b) groove 16, bore 23, valve 21. On downward movement of piston 2 from the position shown, only path (a) is open and flow takes place from chamber 5 to chamber 6. On upward movement of the piston path (a) is closed and path (b) is opened for flow in the opposite direction. Damping is effected by the valves 28, which may be supplemented by unvalved damping ports 25a. In Fig; 2 the piston-rod is solid and the opposite flow paths are both wholly within the piston. Spring loaded rings 29, 30 are so arranged that each can close one but net the other of the channels 23, 24. Movement of the piston to either side of the central position shown compresses one of the ring loading springs 31, 32 and moves the piston out of the range of action of the other. This firmly closes one of the channels 23, 24 and opens, the other. Figs,. 3, to 5 (not shown) depict details of the piston and associated rings of Fig. 2. The piston is made in several superposed generally circular parts and is fitted with axially projecting plungers which, when one ring moves to its channel closing position, positively displace the opposite ring away from the piston.

Title: Improvements in or relating to the preparation of detergent compositions
Inventor: DUNBAR CHARLES
IPC: C11D3/075
Filed: 1950-03-21
Abstract: The condensation product of ethylene oxide with a phenol, cresol or xylenol substituted in the nucleus by one or more higher alkyl groups of at least 8 carbon atoms, the condensation product containing 8-16 oxyethylene groups, is mixed with 25-300 per cent of its own weight of disodium dihydrogen pyrophosphate and/or tetrasodium pyrophosphate and, if necessary, with an inorganic buffer, so that the final mixture has a pH of 6.5-8.5 on being diluted with 100 times its weight of water.  The composition has detergent properties and may be used on cotton at or near the boil and on wool at 50 DEG C.  Suitable phenols include p-1:1:3:3-tetramethylbutyl-o-cresol, 6-11:11:11:31-tetramethylbutyl-2:4 dimethylphenol, mixed p-tertiary-dodecylphenols, mixed p-tertiary-undecylphenols, mixed secondary-dodecyl cresylic acids, kerylphenol and 4:6-di-(11:11:31:31-tetramethylbutyl) -o-cresol.  The builder preferably comprises substantially equal parts of tetrasodium pyrophosphate and disodium dihydrogen pyrophosphate.  If the builder is alkaline, an acid buffer salt may be necessary in the composition, and may be chosen from salts such as sodium hydrogen sulphate, sodium dihydrogen orthophosphate and the corresponding water-soluble salts of metals other than sodium.  When the builder is acid, alkaline buffer salts such as sodium orthophosphate, sodium carbonate and sodium silicate may be employed.  Inert water-soluble diluents such as sodium sulphate, sodium chloride and urea may also be present. Other additional ingredients include secondary longchain alkyl sulphates and alkyl aryl sulphonates to improve the lathering properties, mild oxidising agents such as sodium percarbonate and sodium perborate, an "optical bleach" and sodium carboxymethyl cellulose.  In the example the detergent effects on cotton at 90 DEG C and wool at 50 DEG C of ethylene oxide condensation products having differing numbers of polyglycol ether groups with and without the pyrophosphate builder are compared.  The condensation products are prepared by alkylating ortho-rich cresylic acid with commercial isobutylene to produce tetramethylbutyl cresylic acid mixed with a little di-(tetramethylbutyl) cresylic acid, and this mixture is condensed with ethylene oxide to give products containing 6-18 oxyethylene groups.  The detergent composition comprises 0.04 per cent by weight of the condensation product with and without the addition of 200 per cent by weight of the condensate of a 1:1 mixture of tetrasodium pyrophosphate and disodium dihydrogen pyrophosphate. Specification 696,032 is referred to.
