Title: Improvements in or relating to devices for raising sunken vessels
IPC: B63C7/06
Filed: 1942-08-20
Abstract: 559,313. Raising sunken vessels. SCOFIELD, W. W. Aug. 20, 1942, No. 11757. Convention date, Oct. 6, 1941. [Class 68 (ii)] A grab for raising sunken vessels comprises one or more pairs of pivoted jaws each jaw being provided with two floats the buoyancy of one of which tends to close the jaw and of the other to open it ; the floats being also used to lower and raise the grab in water. The jaws 12 pivoted together at 11 are each secured to a pair of floats 13, 14, float 13 extending substantially upwards and 14 being downwardly inclined from the pivot. The floats are controlled by connections 20, 21 to a surface vessel 26 equipped with pumps and valves 25, 27, connections 21 being extended into floats 13 to permit trapping of some air, and water apertures 23, 24 being provided in all the floats. The grab is towed into position on the surface, the floats being all buoyant and the jaws closed due to buoyancy of floats 14. Floats 14 are filled with water to open the jaws and the buoyancy of floats 13 is reduced until sinking occurs. When the grab has descended to the vessel, floats 14 are filled with air to close the jaws which may be designed so that the weight of the vessel will not subsequently open then, or they may be held by an automatic catch 31. The grab and vessel are then raised by pumping air into floats 13.

Title: Improvements in receiving systems for wireless telegraphy and telephony
IPC: H04B1/12
Filed: 1919-05-13
Abstract: 149,435. Round, H. J. May 13, 1919. Wireless signalling.-In the heterodyne system of reception of wireless signals, the phase of the beat current is adjusted by varying the phase of the heterodyne current or of the signal waves, the beat current thus being brought into phase with, or opposition to, a second current of the same frequency. The system may be utilized for cutting out undesired signals by employing two receiving aerials spaced apart to produce phase displacement in the signal currents, and adjusting the phase of the heterodyne currents so that the beat currents are in phase or in opposition, and can be arranged to balance each other. The method depends on the fact that when two high-frequency currents are beating, and one of them is advanced in phase through a certain angle, the phase of the beat is shifted through the same angle. Fig. 2 shows a receiving-apparatus arranged for cutting-out undesired signals arriving in the plane of the two receiving-aerials A<1>, A<2>. An auxiliary transmitting-aerial A<3> supplies the heterodyne energy to the receiving aerials A<1>, A<2>. As the aerial A<3> lies in the direction from which the signals are arriving, the heterodyne current and the signal current will be in phase at the same moments in both aerials A<1>, A<2>; that is to say the beat currents will be in phase. The beat currents appear in the transformers T<1>, T<2> after rectification by the detectors R<1>, R<2>; and are arranged to balance each other in the transformer T<3>, which has a third winding connected to a telephone X. Signals arriving from other directions produce beatcurrents out of phase and are therefore heard in the telephone. The telephone may be remote from the aerials. A number of aerials such as those used in parabolic formations may be similarly connected to a distant receiving-instrument. The beat frequency may be beyond the audible limit.

Title: Improvements in or relating to preparation of m- and p-diisopropylbenzene
IPC: C07C2/68
Filed: 1954-04-26
Abstract: A mixture of m- and p-diisopropylbenzene substantially free from o-diisopropylbenzene and trimethyl indene is produced by contacting in an alkylation process benzene or cumene with propylene at a temperature of 65-115 DEG  C. in the presence of 0.1 to 2 mols. per cent of aluminium chloride based on the reaction mixture.  The catalyst is first converted into a slurry with benzene or cumene, and in the latter case the slurry is heated to 70-80 DEG  C. and sprayed with anhydrous hydrogen chloride for 15-20 minutes to form a complex, and the propylene added at about 65 DEG  C. and the temperature allowed to rise slowly to about 80-100 DEG  C. and the reaction stopped as soon as the required amount of propylene has been added. The catalyst is removed by treatment with dilute hydrochloric acid, filtering and washing, and then substantially pure m-diisopropylbenzene removed by distillation. Specifications 763,180 and 763,183 are referred to.
