Patent GB-689734-A (GB)
Title: Decomposition of organic peroxides
Inventor: ARMSTRONG GODFREY PAUL
IPC: C07C45/53
Filed: 1949-04-29
Abstract: Phenols and ketones are obtained by the decomposition of hydroperoxides of lower alkyl benzenes with aqueous sulphuric acid of a concentration of not less than 9 per cent w./w., the decomposition being effected at a temperature not exceeding 40 DEG  C. The hydroperoxide starting materials are defined as those wherein the peroxide group is linked to an aliphatic tertiary carbon atom attached to the benzene ring and the alkyl groups do not contain more than five carbon atoms.  The decomposition is preferably effected at 20 DEG  to 40 DEG  C. but lower temperatures, e.g. of about 0 DEG C., may also be used.  It may be carried out by bringing the acid into intimate contact with a solution of the hydroperoxide in an inert water-immiscible solvent which may be the initial alkyl benzene from which the hydroperoxide is derived and it is preferred to use as such a solution the reaction mixture resulting from the oxidation of the alkyl benzene at elevated temperatures with molecular oxygen and the manufacture thereby of the corresponding hydroperoxide.  The aqueous sulphuric acid may be used in concentrations as high as 65.0 per cent H2SO4 w./w. or even higher.  The process may be carried out in a continuous manner and in this case it may be carried out in more than one stage, e.g. by using more than one reactor vessel in series. In the first vessel a fresh solution of the hydroperoxide in unreacted hydrocarbon is added continuously to the aqueous acid contained in the reactor at such a rate as to maintain the hydroperoxide concentration in the hydrocarbon at a constant level which is a fraction of the initial concentration of the added hydroperoxide solution.  A part of the mixture of the aqueous acid and the oil phase which contains the decomposition products is passed continuously to a separator, the aqueous acid being returned to the reactor whilst the oil phase is made to overflow from the separator at a rate equal to that at which fresh hydroperoxide solution is fed to the reactor.  The oil phase is then passed to a further reaction vessel or vessels where it is again contacted with aqueous acid to complete the decomposition of the hydroperoxide.  Examples describe the decomposition of isopropylbenzene hydroperoxide to form phenol and acetone, the isopropyl hydroperoxide being used in the form of its solution in isopropylbenzene, both continuous and batchwise processes being described.  Specifications 626,095 and 641,250 are referred to.

Title: Improvements in or relating to a hydraulic machine including a turbine or pump wheel
IPC: F03B11/00
Filed: 1967-03-14
Abstract: 1,117,837. Hydraulic turbines; centrifugal pumps. ATELIERS DES CHARMILLES S. A. March 14, 1967 [April 1, 1966], No. 11816/67. Headings F1C and F1T. A hydraulic turbine or pump in which water is supplied to a running seal when the runner is being driven in the unloaded and empty state is provided with a lip to deflect the water leaving the seal into a discharge duct and away from the principal faces of the runner so as to reduce resistance losses. In the case of a centrifugal pump having a runner 2 mounted on a horizontal or vertical shaft 1 which also carries a turbine and an electrical machine, water is supplied to seals 7, 10 through ducts 14, 16, respectively, when the pump is being driven in the empty state. Water leaving seal 7 is deflected by lips 20, 31 on the runner 2 into discharge ducts 22, 32, respectively, and a similar lip 21 deflects the water leaving seal 10 into a duct 23. Thus the sealing water does not flow to the clearances between the principal faces 18,19 of the runner and the adjacent stator parts 3,4 and resistance losses are reduced. Air is also supplied in the regions of the seals through ducts 26, 27, 34; ducts 26, 27 may lead to the clearances between the runner faces 18, 19 and the stator parts 3.4. All the air and water ducts are provided with control valves. In a modification, Fig. 2 (not shown), the deflecting lips are mounted on the stator and comprise rings (38, 42) of metal, rubber or plastic mounted in annular grooves (37, 41) in the parts 3, 4. The same construction is applicable to a turbine.

Title: Improvements relating to book-keeping machines and the like
IPC: B41J11/46
Filed: 1956-04-19
Abstract: 818,078. Statistical apparatus. DIRKS, G. July 8, 1957 [April 19, 1956], No. 11889/56. Class 106 (1). [Also in Group XVI] An apparatus for feeding a sheet to a predetermined one of a number of possible positions has means for sensing in succession a series of marks on the sheet, the marks being co-ordinated with the possible positions, a counter responsive to the marks, means for pre-setting the counter in accordance with a required position and means for arresting the sheet in response to the occurrence of a pre-determined count in the counter. In one embodiment the sheet is arrested when the counter registers the predetermined count and in another when a device which senses a continuous signal fails to detect that signal. A sheet 3, Fig. 1, is driven in the direction of arrow 4 by a roller 1 turned by motor 5 through a clutch 6. Sheet 3, Fig. 2, has lines 9/1 to 9/8, each of which has an associated mark 10/1 to 10/8, e.g. holes, printed marks or magnetic marks, which may be sensed by a suitable device. A sensing head 18 senses the marks which are counted by a multicathode gas-discharge tube which steps once for every mark sensed. Pre-setting of the counter is effected by closing the appropriate one of key contacts 14/1 to 14/8, thus any line may be selected. The counter fires valve 22 which operates a magnet brake 7 to stop the sheet feed mechanism. Opening contacts 24 releases magnetic brake 7 and allows clutch 6 to once again drive roller 1 to eject the paper. Grippers may be used to arrest the sheet instead of a magnetic brake. Instead of moving the paper, the sensing head may first scan the marks and be arrested in a position indicated by the counter. The head is then restored to its starting position, a sheet feeding mechanism being engaged to feed the sheet an equivalent distance. A chain of electronic counting stages may be used instead of the multi-cathode gasdischarge tube. An initiating mark, sensed by a second sensing head in conjunction with a gate circuit, may be used so that the counter does not start to count until the additional mark is sensed.
