Title: Separation of cyclohexanol and cyclohexanone from mixtures thereof with cyclohexane
Filed: 1961-04-11
Abstract: The invention comprises a process for the separation of a mixture of cyclohexanol and cyclohexanone from a mixture of cyclohexanol, cyclohexanone and cyclohexane which comprises extracting the latter mixture with diethylene glycol and separating the extract from the raffinate. The mixture of cyclohexanol, cyclohexanone, and cyclohexane may be produced by the partial oxidation of cyclohexane in the liquid phase with an oxygen containing gas e.g. oxidation at 75 DEG C.-200 DEG C. and at a pressure of 50-500 lbs. per square inch preferably at a temperature of 125 DEG C. to 175 DEG C. at a pressure of 100 to 150 lbs. per square inch in the presence of a hydrocarbon soluble oxidation catalyst. The extraction is preferably carried out at 20 DEG C. to 50 DEG C. and preferably using 0.25 to 4 volumes to diethylene glycol to extract each volume of mixture of the cyclohexanol, cyclohexanone and cyclohexane. After removal of a cyclohexane, cyclohexanol, cyclohexanone from the extract the residue may be reused to extract a further quantity of the mixture. In an example 500 parts of cyclohexane, 2.5 parts of cyclohexanone and 0.25 parts of cobalt naphthenate are agitated in an autoclave and air is fed into the reaction mixture at a rate of 0.005 cubic feet per minute per molecule of cyclohexane until an oxygen consumption of substantially 1/12th of a molecule per molecule of cyclohexane is obtained, the consumption being determined by analysis of oxygen content of a measured volume of the withdrawn gases, when the reaction mixture is cooled to 60 DEG C. To the cooled reaction mixture (517.5 parts, cyclohexanol 4.52% and cyclohexanone 3.33%) diethylene glycol is added in an amount equal to twice the weight of the reaction mixture, thoroughly agitated and allowed to settle, when the diethylene glycol layer is withdrawn. This procedure is repeated with more diethylene glycol. The cyclohexane layer remaining (430 parts of cyclohexane and 2.5 parts of cyclohexanone) is suitable for re-use in the autoclave. The extract has the following composition. Diethylene glycol 1985.0 parts, cyclohexanol 23.4 parts, cyclohexanone 14.7 parts, cyclohexane 35.0 parts, water 7.0 parts, acids and esters 4.9 parts.

Abstract: 716,873. Valve circuits for radio reception. PYE, Ltd. May 28, 1952 [June 1, 1951], No. 13055/51. Class 40 (6) In a receiver for alternative operation on battery or mains supply, in which a heater type output valve V5 is provided for mains operation. the grid of this valve is directly coupled to the anode of a preceding valve V3, in order to stabilize the filament current of the remaining valves V1, 2, 3. Valves 1, 2, 3 are of filament type and connected in series; with switch S4 closed, their filaments are also in series with the filament of valve V4, which comprises the output valve for battery operation, and across battery B. Switches S2, 6 are closed also and apply battery H.T. to valves V1, 2 over resistor R4 and to valve V3 over screen and anode resistors R2, 5 respectively. The valve V3 comprises the penultimate audio stage and is coupled to output valve V4 over a blocking condenser C3. To operate from mains supply, switches S1, 3, 5 are closed instead. The valves V1, 2, 3 then obtain a filament supply from the cathode current of valve V5, via a non-linear resistor R1. H.T. supply for valves V1, 2 comes from the screen circuit of the valve V5, while the screen of valve V3 is fed from a tap on the resistor R1. As the grid of valve V5 is direct-coupled to the anode of valve V3, any change in the cathode current of valve V5 causes a change in the emission and so in the anode current of valve V3 which varies the grid potential of valve V5 in such a sense as to restore its cathode current to the predetermined value. The control may alternatively be applied to the suppressor grid of valve V5 instead of the control grid.

Title: Cartridge for automatic gun
IPC: F42B5/285
Filed: 1943-08-12
Abstract: 576,726. Cartridges. KELLER, S., and KELLER, E. Aug. 12, 1943, No. 13098. [Class 9 (i)] A cartridge for an automatic gun is so designed that on initial impact of the breech block to drive the cartridge towards the breech, relative displacement or deformation of parts of the cartridge is produced, this displacement or deformation damping or partly absorbing the impact of the blow. By this means the cartridge is prevented from being accelerated excessively and thus from getting in front of the extractor claw. Four examples are described: (1) the cartridge case 1 is crimped at its forward end 2 in a recess 3 in the projectile, when the case is struck by the breech block, the end moves forward until it abuts against the guide ring 4 on the projectile ; (2) the case is in two partly telescoped parts, which are fully telescoped by the impact of the breech block ; (3) the base 11 is held in the case 1 by a fine thread 12 which is stripped by the impact; (4) projections 13 on the base of the case are deformed by the impact. Specification 14915/14, [Class 9 (i)], is referred to.

Filed: 1942-09-18
Abstract: 556,259. Electric signalling systems. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 18, 1942, No. 13225. Convention date, Sept. 18, 1941. [Class 40 (i)] [Also in Group XL] In a system having rotating parts at the transmitter and receiver which are kept in synchronism by the transmission of alternating or fluctuating current over the channel between them, the position of a pointer is signalled by a momentary interruption of the synchronizing current in each revolution. In Figs. 1, 2, a synchronous motor 16 driving an arm 15 is fed with A.C. which is also transmitted over a wireless channel to the receiver, where it is employed through a valve 28 and transformer 27 to energize a split-phase motor 31 driving a pointer 13. The arm 15 makes contact once per revolution with the pointer 10 of an instrument 14 and interrupts the supply of synchronizing current. The motor 16 operates through reduction gearing 22 so that the interruption covers one to two cycles of the A.C., while the motor 31 operates through similar gearing 22a and a fly-wheel 34 to avoid loss of synchronism. A neon lamp 37 normally receives opposing voltages from transformers 27, 36, but when the interruption occurs the motor 31 acts as a generator and feeds back through the transformer 27 a voltage which flashes the lamp to illuminate the pointer 13. In Fig. 5, the indications of two pointers 43, 44 movable over arcuate scales are signalled over the same transmission channel 40. A.C. from which the negative half-cycles are suppressed by a valve 48 is fed to a synchronous motor 55 and over the channel 40 to energize the split-phase motor 31. The motor 55 drives a disc 54 having an aperture 56 which at appropriate points in its rotation allows light from a source 53 to pass to mirrors 57, 58 carried by the pointers and be reflected on a photocell 52. When this occurs the negative bias of the valve 48 is increased to interrupt the synchronizing current, and the lamp 37 is flashed to illuminate the pointer 47 as in Figs. 1, 2, two scales 45a, 46a being provided corresponding to those of the pointers 43, 44.
