Patent GB-730896-A (GB)
Title: Improvements in and relating to organic hydroperoxides
IPC: C07C409/10
Filed: 1952-10-31
Abstract: In a process of preparing organic hydroperoxides an aromatic compound having at least one substituent of the formula <FORM:0730896/IV (b)/1> wherein R1 and R2 are alkyl groups, is intermittently and alternately oxidized with ozonized oxygen and non-ozonized molecular oxygen.  Oxidation is preferably carried out at elevated temperature, preferably in the range 40-80 DEG  C. and in the presence of a catalyst such as an organic or inorganic peroxide (e.g. barium, benzoyl or acetyl peroxide) or hydroperoxide (e.g. cumene hydroperoxide), or an inorganic oxide or hydroxide.  The process is also preferably carried out in presence of acid-binding agents such as alkali hydroxides (e.g. sodium hydroxide), alkali carbonates, alkali bicarbonates, organic bases (e.g. triethanolamine) and alkaline reacting salts of organic acids and soaps (e.g. sodium stearate).  The ozone content of the oxygen or oxygen-containing gas used for oxidation may be up to 7.5 per cent by volume but is preferably between 0.5 and 1.5 per cent by volume.  The ozonized oxygen is preferably supplied for periods of shorter duration than those wherein non-ozonized oxygen is introduced (e.g. 5 minutes ozonized oxygen treatment every one to two hours).  A proportion of the mixture resulting from the oxidation may be continuously withdrawn when the concentration of hydroperoxide formed in the mixture is about 35 per cent, this being continuously replaced by a corresponding proportion of the aromatic compound used as starting material.  The examples describe the preparation of the hydroperoxides of cumene, para-cymene, 1-isopropyl naphthalene and diisopropyl benzene.

A furnace chamber casing, Fig. 4, arranged to be suspended from the upper closure of a pressure chamber, comprises three gas-tight metal tubes 61, 62, 63 suspended from an attachment ring 64. The inner tubes 61, 62 are guided at the lower end by a ring 65 attached to the outer tube 63, and the space between them is filled by thermal insulation 68. Porous thermal insulation 69 is secured to the outside of tube 62 by a helical strip or rings 70, and porous insulation 71, 72 is secured on both sides of the outer tube 63 by strips or rings 73, 74.

Title: Improvements relating to pneumatic compensating suspensions for vehicles
IPC: B60G17/052
Filed: 1956-09-12
Abstract: 807,138. Road-vehicle pneumatic-spring suspensions. DAIMLER-BENZ A. G. Sept. 12, 1956 [Sept. 12, 1955], No. 27909/56. Classes 108(2) and 108(3) The invention relates to vehicle suspension systems in which a pressure-compensating pipeline interconnects respective road-wheel pneumatic springs 2, 4. According to the invention at least one of the springs are of the kind in which the effective cross-section of the movable part of the spring, on which the pneumatic pressure acts, varies with deflection of the spring. As shown, the cross-section of the front wheel spring remains constant with deflection, while the rear wheel spring (shown diagrammatically). cross section increases with increased compression movement of the spring. On a pre-determined degree of deflection of the front wheel 1, a valve 14 (connected at 13 to the wheel suspension arm 12) is operated to admit air to the pipe 10 from a reservoir 15. The latter may be charged from a compressor, or may be replaced by another charged container when necessary. The springs 2 or 4 may be replaced by the spring shown in Fig. 6, in which the cross section decreases with increased compression movement. In another construction (Fig 7, not shown) the bellows 616 is in the form of a tubular sleeve extending between the relatively movable members 602, 607 which are spaced apart and have annular flared abutment faces which afford progressive supporting area as compression increases. In the latter construction, the bellows sleeve is constricted by a rigid ring.
