Title: New salts of basic ethers of diphenyl ethinyl carbinols and the production thereof
Inventor: ARNOLD HERBERT
Filed: 1957-01-30
Abstract: The invention comprises salts of basic ethers of the general formula <FORM:0812493/IV (b)/1> wherein R1 and R2 are alkyl groups containing 1-3 carbon atoms and one or both phenyl groups are substituted by halogen atoms, and the preparation thereof by reacting a halogen substituted benzophenone with acetylene and an alkali metal in liquid ammonia, condensing the ethinyl carbinol so formed with a base of the general formula <FORM:0812493/IV (b)/2> in the presence of an alkaline substance and converting the basic ether into a salt.  In an example 4-chlorobenzophenone is reacted with acetylene in the presence of sodium in liquid ammonia to form 4-chloro-a -ethinyl-benzhydrol, which is reacted with dimethylaminoethyl chloride, in the presence of sodamide, to form b  - dimethylaminoethyl - (4 - chloro - a  - ethylinyl-benzhydryl) ether. Reaction of the base with an ethereal solution of hydrogen chloride gives the hydrochloride and with ethyl iodide or dimethyl sulphate the corresponding quaternary ammonium salts, N-dimethyl-N-ethyl-N-[b -(4-chloro - a  - ethinyl - diphinylmethoxy) - ethyl]-ammonium iodide and N-trimethyl-N-[b -(4-chloro - a  - ethinyl - diphenylmethoxy) - ethyl] ammonium methosulphate.  Similarly are prepared: b  - diethylaminoethyl - (4 - chloro - a -ethinylbenzhydryl) ether and its hydrochloride, N - triethyl - N - [b  - (4 - chloro - a  - ethinyl - diphenylmethoxy)-ethyl] ammonium iodide, and N - methyl - N - diethyl - N - [b  - (4 - chloro - a -ethinyldiphenylmethoxy) - ethyl] ammonium methosulphate. 4,41-Dichloro-a -ethinyl-benzhydrol (from 4,41-dichloro-benzophenone) is reacted similarly with dimethylaminoethyl chloride to give b -dimethylaminoethyl-(4,41-dichloro - a  - ethinyl - benzhydryl) ether and its hydrochloride.  The b -diethylaminoethyl-(4-bromo - and 4 - fluoro - a  - ethinyl - benzhydryl) ether hydrochlorides and b -dimethy-aminoethyl - (4 - fluoro - a  - ethinyl - benzhydrly) ether hydrochloride are also specifically disclosed in a table relating to pharmacological activities.

Title: Improvements in or relating to hydraulic systems
IPC: B62D49/00
Filed: 1957-02-04
Abstract: 807,180. Tractor power-lift mechanisms. INTERNATIONAL HARVESTER CO. Feb. 4, 1957 [March 15, 1956], No. 3764/57. Class 79(1) [Also in Group XXIX] A positional control hydraulic system embodying a double-acting ram and suitable for application to the power lift system of an agricultural tractor comprises control means operable to provide free return flow of hydraulic fluid from both ends of the ram cylinder to establish a "floating" action of the ram without affecting the setting of the position control of the system, so that the ram takes up the position predetermined by the position of the control lever of the positional control mechanism when the "floating" action is discontinued. The system is suitable for enabling an implement carried by a tractor to accommodate itself to irregularities of the ground. In one embodiment a double acting servo-piston 2 is connected by a link 3 to a lever 5 mounted on a shaft 6 which is connected to implement hitch means on an agricultural tractor, the piston being controlled by a valve 10a connected by a floating lever 15 with a control lever 13 and by a follow-up link 16 with the lever 5. A valve 17 interposed between the valve 10a and the servo-piston 2 is actuable by a lever 19. When the valve 17 is in the position shown it establishes the floating condition of the servo-piston and also connects a hydraulic fluid supply passage 8a with an exhaust passage 11 by means of a drilling 22 communicating with grooves 21a, 21b, 21c. On movement of the valve 17 to the right the communications with the exhaust conduit 11 are interrupted and the servo-piston is controlled by the valve 10a. In a modification, in which the conduits between the control valve and the two ends of the cylinder containing the servo-piston are provided with non-return valves to provide hydraulic lock as in Specification 794,147 [Group XXIX], the means for establishing the "floating" condition of the servo-piston comprises levers for simultaneously opening both non-return valves. In a further modification, each conduit between one end of the servo-cylinder and its control valve is provided with a passage leading to exhaust by way of a non-return valve, the two non-return valves being operated simultaneously through a lever and linkage system.

Title: Improvements in terminal apparatus for electric signalling systems
IPC: H03C7/02
Filed: 1944-03-01
Abstract: 575,432. Wave guides; radiolocation. WESTERN ELECTRIC CO., Inc. March 1, 1944, No. 3883. Convention date, Jan. 30, 1943. [Class 40 (v)] When a transmitter and a receiver are branched on the same aerial, the receiver is protected by means of a cavity resonator interposed in the receiver branch and provided with a spark-gap which breaks down under the influence of the transmitted energy. As shown, a magnetron generator M feeds a wave guide 2 of rectangular section through a coaxial line 1, the guide extending to an electromagnetic horn A. The receiving apparatus comprises a branch guide 5 which is attached to an inner guide 4 slidable within the main guide 2 which. is cut away at 3 to permit adjustment. The length of the inner guide 4 is an integral number of half-wavelengths, and it is slotted to permit wave energy to enter the branch 5. The latter is divided into three sections communicating by irises 11, 14 and is terminated by a tuning piston 6. Local oscillations from a source 25 are fed by a coaxial line 26 to the resonant outer compartment 24, and the innermost compartment is formed as a cylindrical resonator 9. The middle compartment contains a detector 16 mounted on the inner line line of a coaxial cable 18. Mixing of the received and local oscillations in the detector 16 results in an intermediate frequency being fed out to an amplifier 20, second detector 21 and receiving or recording instrument 22. The resonator 9 has spark-gap electrodes 13 connected to its upper and lower walls, and during transmission, the wave voltage is sufficient to break down the gap, and substantially no energy passes to the receiver. During reception, received energy passes readily to the receiver, its passage towards the magnetron 1 being prevented by suitably adjusting the position of the branch guide 5. The axis of the branch guide 5 may be at right angles to the wide faces of the rectangular main guide 2. The arrangement may be used for two-way signalling or for radiolocation.
