Title: Process for the preparation of organic isocyanates
Inventor: BLOOM ALBERT
IPC: C07C263/10
Filed: 1957-09-17
Abstract: In a process for the preparation of isocyanates, an organic primary amine is reacted with slightly more than one half molar proportion of phosgene for each amino group in the amine, at about 0-10 DEG  C. in an inert organic solvent to produce a slurry of a carbamyl chloride-hydrochloride in said solvent, and the slurry so obtained is reacted at a temperature of 100-200 DEG  C. with further phosgene in excess of that required to fully react with the carbamyl chloride-hydrochloride so that the desired isocyanate is formed, and the process is characterized in that the inert organic solvent employed in the reaction consists of at least one of the following compounds: dialkyl ethers of mono -, di -, or tri - alkylene glycols of the formula <FORM:0834082/IV (b)/1> (where R is alkyl, n is 1, 2 or 3, and R1 is H or methyl or ethyl), mono- or di-alkyl (1-8 C) phenyl ethers, dialkyl (1-8 C) ketones, alkyl (1-4 C) phenyl ketones, dialkyl (2-14 C atoms) esters of aliphatic di-carboxylic acids of at least 5 carbon atoms, dialkyl (2-14 C) esters of aromatic dicarboxylic acids; alkyl, aryl, or mixed alkyl-aryl triester of orthophosphoric acid; a mixture of one or more of the above solvents with a normally liquid alkylated benzene hydrocarbon containing 1-3 alkyl substituents or a mixture of such alkylated benzene hydrocarbons. Specified alkylated benzene hydrocarbons are toluene, xylenes, trimethyl benzenes, butyl benzenes, and others.  Commercial aromatic petroleum solvents containing 75-98.5% aromatics and of boiling range 106-182.2 DEG  C. may be used.  Specified dialkyl ethers of glycols include those of ethylene, diethylene, triethylene, propylene and dipropylene glycol, e.g. dimethyl, ethyl propyl and propyl butyl ethers.  Amongst examples of the other types of compounds used as an inert solvent are anisole, isobutyl phenyl ether, 1-methoxy-3-amyloxybenzene, methyl propyl ketone diisobutyl ketone, acetophenone, or butyl phenyl ketone, dihexyl suberate, di-ethoxy ethyl sebacate, didecyl phthalate, esters of diphenic and 1,8 naphthalic acid, triamyl phosphate, triphenyl phosphate and tri-(2-ethyl hexyl) phosphate.  Many mono- and di-amines are specified as starting materials. Specification 805,249 is referred to.

Title: Improvements in and relating to variable load braking apparatus
IPC: B60T8/18
Filed: 1935-10-23
Abstract: 447,242. Fluid pressure brakes. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., 82, York Road, King's Cross, London.- (Assignees of Compagnie des Freins Westing- house ; 23, Rue d'Athenes, Paris) Oct. 23, 1935, No. 29296. Convention date, Dec. 29, 1934. [Class 103 (i)] In fluid-pressure brakes in which the effort is varied according to the load, the transmission ratio of the brake rigging is varied by means of a portion 49, the piston rod 51 of which is connected to the rigging. The piston 49 is controlled by a relay valve 45 and a control valve 1 having differential pistons 6, 14 connected together and operating a slide valve 5 and connected by a rod 40 to a bell-crank 2 engaging the vehicle axle box 4. When the vehicle is empty and the train pipe 3 at atmospheric pressure, the bell-crank allows a spring 7 to move the pistons 6, 14 and the slide valve 5 to the right. When the train pipe is charged, fluid flows by pipes 15, 16, cavity 17 of the slide valve 5 and pipe 19 to the left of the piston 20 of the relay valve 45 and fluid also flows from the triple valve chamber 24, by the passage 23 to the right of the piston 20. A spring 22 therefore maintains the piston 20 in its right-hand position and connects the piston 49 to atmosphere by pipe and passage 26, cavity 27 and passage 28. Train pipe pressure eventually acting on the piston 14, moves the differential pistons to the left, thus moving the bell-crank 2 away from the axle box 4 and putting the adjusting device out of action. When loaded the movement of the axle box, by means of the bell-crank 2 moves the slide valve 5 to the left, and so that it is disengaged from the piston 14, and the left of the piston 20 is vented to atmosphere by means of the pipe 19, cavity 30, passage 52 the chamber 37 and by leakage past the piston 6. When the train pipe is charged, the train pipe fluid acting on the right of the piston 20 moves the valve 21 to the left, and passes by the passage 26 to the piston 49 which it moves to displace a fixed point of the brake rigging and alter its leverage. A spring ball 8 and a cam surface 9 drive the valve 5 at the end of its movement to the right against the piston 14. A lever 10 pivoted to the valve 5 at 11, engaged by the piston rod at 12 and fulcrumed on the ball 8 gives a movement to the valve several times greater than that of the piston rod. When the piston 14 has moved to the left past a cavity 31, the cavity admits fluid to the piston 6 to apply it pivotally to its seat 32. Valve 33 is used to vent fluid that may leak past the slide valve 5 on the piston 20, when the apparatus has been placed previously in the loaded position. Specifications 348,147 and 354,423 are referred to.

Abstract: 337,150. Milliken Bros., Ltd., (Assignees of Prescott, L. A., and Marshall, I. W.). July 25, 1929, [Convention date]. Systems of supporting conductors; posts.-In an overhead electrical transmission system of the type in which the conductors are suspended by insulator chains and an earth-wire is carried above the uppermost conductor for protecting the system against lightning discharge, the supports for the earth-wire are adjustably mounted so that the earth-wire and conductors occupy the same relative positions throughout the system. In the construction shown, conductors 6, 7, which are suspended by insulator chains 8, 9 from the cross-arm 4 of a lattice-work mast 1, are protected by earth-wires 10, 11. The earth-wires are carried by a beam 12, which is supported at the top of the mast 1 by struts 25, 26 provided with angle-irons 24, 27. Fig. 1 shows the disposition of the conductors 8, 9 and the earth-wires 10, 11 on a straight portion of the system, the beam 12 then being centrally disposed with respect to the axis of the mast. When the direction of the conductors changes, the insulator chains 8, 9 become inclined to the vertical, as in Fig. 2, and in order to maintain the same relative disposition of the conductors and earth-wires the beam 12 must be displaced laterally as shown. The beam 12 which is formed of channel-bars 16 connected at intervals by plates 17, as shown in Figs. 5 and 6, is secured to angle-irons 24, 27 by bolts 15. A series of holes 14 formed in the flanges of the channel-bars 16 for the reception of the bolts 15, permits lateral adjustment of the beam 12.
