The compounds are prepared by reacting the appropriate diaminobenzonitriles with compounds of the formulµ wherein Hal is halogen and Alk is C 1-3  alkyl, and if desired, transesterifying the resulting esters. 2,4-Diaminobenzonitrile is prepared by reducing 2,4-dinitrobenzonitrile, obtained by heating 2,4-dinitrobenzoic acid with benzenesulphonamide. 2,5-Diaminobenzonitrile is obtained by reducing 2-amino-5-nitrobenzonitrile with stannous chloride. Pharmaceutical compositions, suitable for administration orally, by inhalation, parenterally, or rectally, contain the above compound together with suitable pharmaceutical carriers. The compounds are used in the prophylactic treatment of sensitized humans and animals for allergy and all anaphylactic reactions of a reagin or non-reagin mediated nature.

Title: Improvements in and apparatus for the release of pressure from high pressure mixtures of liquids and gases, and, if desired, solids
IPC: F01L25/06
Filed: 1937-09-07
Abstract: 502,091. Regulating liquids. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) Sept. 7, 1937, No. 24405. [Class 135] A high-pressure liquid, in particular a liquid containing solid matter in suspension, e.g. the residue withdrawn from the reaction vessel or hot catchpot in plant for the destructive distillation of coal, is released from pressure by admitting the mixture in small quantities to a cylinder Z in which a piston K is adapted to be reciprocated and which is provided with a valve - controlled inlet A for the high-pressure mixture, a valve controlled outlet B for the mixture at low pressure, and high and low-pressure auxiliary-liquid conduits o, n respectively controlled by valves E, C. The Figure shows the cylinder during admission of the high-pressure mixture, with the inlet valve A open and the upper side of the piston subject to the high-pressure auxiliaryliquid, the effective pressure of the latter being slightly less than that of the mixture to be released. The supply of mixture is maintained until the cylinder is filled to a predetermined degree, whereupon the pressure above the piston is reduced by closing the valve E and opening the valve C, so that the piston will move up until the desired degree of pressure release of the mixture is attained. The outlet valve B is then opened to atmosphere and the mixture ejected by the low-pressure auxiliaryliquid until only sufficient of the mixture remains in the cylinder to constitute a brake, when the outlet valve B and valve C are closed and the valve E is opened to cause the brake liquid to be compressed to the pressure of the original mixture. A further quantity of the high-pressure mixture is then admitted to the cylinder. The valves A, B, G, E, are preferably actuated automatically in their proper order by liquid from the conduit o under the combined controls of a piston valve coupled to the rod of the piston K and additional valves subjected to the pressures on the upper side of the piston.

Abstract: 728,764. Winding and reeling. UNITED ENGINEERING & FOUNDRY CO. Oct. 3, 1952 [June 18, 1952], No. 24812/52. Class 83(4). In apparatus for coiling hot strip metal a plurality of guide rolls and guide plates attached to frames form a substantially continuous channel round the reel for guiding the end of the strip. The strip S, Fig. 1, from a rolling mill is fed by pinch rolls 12 through a chute 13 and throat guide 14 to the periphery of the reel 16 and is engaged by a pair of driven rolls 17 which urge it under a pair of curved or spiral guides 18, 19 which partially encircle the reel 16. A further pair of driven rolls 21 engage the strip as it leaves the guides 18, 19 and urges it beneath the oncoming strip being coiled. The guides 18, 19 are mounted on frames 31 arranged to be withdrawn away from the rail as soon as the coil is partially formed by means comprising a photo-electric cell 65 and light source 66 in the shoot 13 which detect the entry of the strip S and actuate solenoid valves in a hydraulic system for withdrawing the frames after a preset time delay. The frames 31 are mounted on bell cranks 32 and arms 37 pivoted on shafts 34, 38 between side frames 11 and are yieldingly held in position by double-acting hydraulic piston and cylinder assemblies 35, 36 connected to the bell crank and actuated to withdraw the guides under control of the photo-electric cell 65.

Abstract: 262,727. Merco Nordstr÷m Valve Co., (Assignees of Nordstr÷m, S. J., and Mills, L. D.). Dec. 12, 1925, [Convention date]. Repairs, facilitating. - A method of grinding lift valves to their seats in situ consists in feeding an abrasive mixture to an intermediate portion of the contacting surfaces while the valve is in the closed position, and then rotating the movable member against the seat. The Figure shows a discharge valve for a tank car adapted to carry the method into effect. The valve member 27 is guided by a spider 43 and is loosely connected to a spindle 15 actuated against the action of a spring 24 by a hand actuated cam 18 engaging a bracket 19 secured to the dome 16 of the tank. The lower end of the spindle is slotted to engage a rib 26 on the bottom of the hollow valve member and is threaded to a gland 32 screwed to a flange 29 on the valve member. Packing 34 arranged between the gland and a collar 35 on the spindle is compressed by rotating the gland which is afterwards secured by a detachable pin 35 engaging one of the ribs 38 formed on the back of the valve member. Abrasive mixture is introduced into the hollow spindle and is forced into the hollow valve member and thence through holes 40 onto the contacting surfaces by means of a plunger adapted to be screwed into the outer end of the spindle. In a modification using a solid valve the mixture is introduced through an aperture in the seat and the valve member has a peripheral groove to ensure even distribution. A hand wheel 23 is secured to the spindle for rotating the valve on its seat.
