Title: Tetrahydronapthylthioureas and tetrahydroaminonapthothiazoles
IPC: C07D277/84
Filed: 1935-11-01
Abstract: ar-Tetrahydronaphthylthioureas useful in the production of safety paper chemicals, insecticides, and dyestuffs are produced by heating ar-tetrahydro-a - or ar-tetrahydro-b -naphthylamine in the form of their water soluble salts with such acids as hydrohalic or sulphuric acids with an alkali thiocyanate in water, dilute alcohol or dilute acetone solution.  These thioureas may be converted into the corresponding thiazoles by means of various ring-closing agents, chiefly oxidizing agents.  Preferred agents mentioned are chlorine, bromine, sulphur chloride, sulphur bromide, sulphuryl chloride, sulphuryl bromide or mixtures of the above.  A mixture of sulphuryl chloride and bromine has been found to give particularly good results.  In examples: (1) an aqueous solution of ar - tetrahydro - b - naphthylamine, hydrochloric acid and ammonium thiocyanate is refluxed for 16 hours when ar-tetrahydro-b -naphthylthiourea separates, and is recrystallized from alcohol; (2) a chlorbenzene solution of ar - tetrahydro - b  - naphthylthiourea is treated with a chlorbenzene solution of a mixture of sulphuryl chloride and bromine. After stirring for one hour a mixture of the hydrochloride and hydrobromide of ar-tetrahydroaminonaphthothiazole separates and is converted into the free base by dissolving in water and treating with ammonia.

Filed: 1946-10-16
Abstract: 618,076. Limiters. BRITISH THOMSONHOUSTON CO., Ltd., and MYNALL, D. J. Oct. 16, 1946, No. 30840. [Class 40 (v)] An amplitude limiter comprises a valve 1 connected by resistances between points respectively positive and negative in potential with respect to earth. The input circuit comprises series resistance 5 and a shunt diode 3, while the cathode is connected to earth over a further diode 4. On positive-going excursions of the input, the grid potential is held constant by conduction in the diode 3. With excursions in the negative sense the valve 1 acts as a cathode follower until the anode current is sufficiently reduced for conduction to occur in the diode 4. The valve cathode is then held at earth potential and further increase of input in a negative direction causes the valve to be cut off.

Abstract: 1317651 Hydraulic motors; hydraulic actuators INTERNATIONAL HARVESTER CO 25 June 1970 [22 July 1969] 30905/70 Headings F1D and F1F A motor including semi-rotary vane or a linear piston movable by the fluid, includes a bleeder valve having a housing connected between a source of hydraulic fluid and the motor and having an inlet port for receiving fluid, a port for delivering fluid to operate the vane or piston and a return port for bleeding fluid from the motor, and a sensing means reciprocable in the housing and responsive to the movement of the vane or piston which is operable on the valve member of the bleeder valve so that when the vane or piston approaches one of two end positions between which it is movable, fluid is withdrawn from the motor through the return port. In one embodiment, a motor 10, Fig. 5, includes a vane 26 having ears 22 which except for V-shaped grooves 23 mask ports 24, 25 in the end positions of the vane. The vane is mounted on a shaft 15 on which is keyed a cam 80, Fig. 4, co-operable with sensing members 61, 61' one for each identical bleeder valve 50 or 50'. Each valve comprises a housing 60 slidably mounting a spring- loaded valve piston 62 and formed with ports 70, 71, 72 connected respectively with a source of pressure fluid via a control valve 99, the motor, and sump also via the control valve. A rear land 62R of the valve piston includes a reduced diameter portion 64 so that as the vane approaches the end of its travel some of the fluid entering the appropriate port to move the vane is increasingly directed through the port 72 to sump to cushion the movement of the vane. The V-shaped grooves 23 on the ears 22 permit the initial admittance of fluid through the appropriate port to commence movement of the vane and a final slow leakage at the end of movement. Axial and radial passages through the valve piston hydraulically balance the valve. In an alternative embodiment a piston 113, Fig.6, reciprocates in a cylinder 110. In this instance a single bleeder valve 150 is fitted. Rings 120 formed with metering grooves 121 are drawn into juxtaposition with port 126 or port 127 as the piston finally approaches the end of its travel.

Filed: 1928-10-25
Abstract: 324,392. Marks, Sir G. C., (Polysius, G.). Oct. 25, 1928. Pneumatic conveyers.-In a conveying system in which the material to be conveyed is contained in hoppers 1, 2 one of which is filled while the other is emptied, the valves closing the inlets and outlets of the vessels are changed from one position to the other by mechanism which is actuated by the increased pressure existing in a hopper from the time it commences to discharge into the conveying pipe 15 until it is emptied. The upper parts of the hoppers communicate by pipes 18, 19 with a pipe 16 connected either to the conveying pipe 15 or to the compressed air pipe 13. Either the pipe 18 or the pipe 19 is put in' communication with the pipe 16 by a valve 17 which is actuated by a link 37 connected to the plunger of a double-acting electromagnet 26. This plunger also is connected by linkwork to the valves 7, 12 and 8, 11 controlling the inlets and outlets, respectively, of the hoppers 2, 1. Diaphragms 35, 36 provided in chambers 20, 21 at the top of the hoppers are connected by rods 22, 23 to tilting mercury vessels 24, 25 which control the circuits of the magnet 26. If the full hopper 1 is about to be emptied and the empty hopper 2 is about to be filled, the parts will be in the position shown. The increase of pressure in the hopper 1 causes the diaphragm 35 to operate the tilting vessel 24 to cut off current from the magnet 26. When the hopper 1 becomes empty, the pressure falls and the return of the diaphragm 35 to its normal position operates the ,vessel 24 to supply current to the magnet 26 so that it becomes energized in the reverse direction to that in which it had operated previously. The movement of the plunger of the magnet puts the pipes 16, 18 into communication, closes the valves 7, 11, and opens the valves 8, 12.
