Title: A process for the purification of terephthalic acid
IPC: C07C51/487
Filed: 1963-04-22
Abstract: A process for the purification of terephthalic acid comprises dissolving the crude or impure terephthalic acid in an aliphatic carboxylic acid having 2 to 5 carbon atoms, e.g. acetic acid, at a temperature of 200 DEG  to 300 DEG  C. and under a pressure sufficient to maintain the solvent in a liquid phase, contacting the solution with a gaseous molecular oxygen or molecular oxygen containing gas, e.g. air, in the presence of at least one oxidation catalyst containing cobalt, manganese, chromium, cerium and lead or their compounds, then cooling the resulting solution to crystallize out pure terephthalic acid and thereafter separating it from the solution.

Title: Continuous oxidation of aromatic compounds with nitric acid
Inventor: BORTHOLOME ERNST
IPC: B01J14/00
Filed: 1963-04-23
Abstract: The parent Specification describes a process in which aromatic mononuclear compounds containing oxidizable side chains are oxidized to the corresponding carboxylic acids with nitric acid at a raised temperature and pressure, the reaction being effected in a vertical reactor through which the reagents flow upwardly and the reagents being mixed, at a temperature below the reaction temperature, before they enter the reactor, the arrangement being such that the speed of the mixture is decreased to at least one third as it enters the reactor.  This process is now modified in that only 30-60% of the required nitric acid is supplied to the mixer, the remainder being supplied directly to the reactor at about the middle third.  As in the parent Specification, the reaction may be effected at 150-400 DEG C. at 10-150 atm. pressure and optionally in the presence of the catalysts named in the parent Specification.  Specified materials which may be oxidized are toluene, xylenes, cymene, diisopropylbenzenes, chlorotoluenes, nitrotoluenes, chloroxylenes, nitroxylenes, mesitylene, durene, toluic acids, benzyl chloride, xylylene dichlororide, chloromethylated xylenes, picolines and ethylpyridines.  An example is given of the oxidation of p-xylene to terephthalic acid.

Ball-jointed hinges; pivoting adjustments. - A double ball-and-socket adjustable pivot for windscreens, mirrors, &c. with means independent of the tightening screw for adjusting the working friction between the parts so as to prevent sudden fall when the screw is loosened, comprises a convex part A fixed to the screen B and having a peripheral internally-threaded projection C into which screws a shell D so as to form a housing for the part E which is cylindrical with concave and convex ends corresponding to the curved portions of A and D. The part E has a square projection H internally threaded at L<1>, which passes through the shell and takes within a square hole H<1> in a cylinder J screwed into the support P for the wind-screen. A tightening-screw L with a handle works in the thread L<1> and has a shoulder K bearing upon the part J through a washer W<2> while the inner face of the part J is made concave and a curved washer W<1> interposed between it and the shell D. In assembling, the shell is first screwed up to give sufficient friction to prevent the screen falling by gravity and is then fixed by a grub-screw. The part J is then adjusted in the support so as to bear upon the outside of the shell through the washer W<1>, fixed by a grub-screw or clamp, and the screw L may then be tightened up to grip the shell between the parts E and J. In the Figure the screen is shown as being out of the vertical, there being sufficient clearance between the parts H and D to allow for such inaccuracies of mounting.

Abstract: 770,945. Valves. CAROLI, G. June 10, 1955 [June 12, 1954], No. 16768/55. Class 135. A valve for controlling the circulation of a hydraulic fluid to a motor driving, for example, a fan cooling water for an internalcombustion engine, in dependence upon the temperature of the cooling medium, comprises a thermostat B, Fig. 1, installed in piping A through which the cooling medium circulates, a spring-loaded valve piston 48 having a rod 50 engageable by a rod 20 of the thermostat and an apertured sleeve 44 in which the valve piston slides to control the flow of oil between a connection 38 connected to a supply pump and a sump connection 39. Connections 41, 40 lead to the inlet and return sides respectively of the hydraulic motor. On an increase in temperature of the cooling medium the rod 20 moves the valve piston 48 against its spring 53 to close sleeve apertures of differing sizes and arranged at varying levels to reduce the amount of oil returned to sump and increase the supply of oil to the hydraulic motor which will eventually start the motor to drive the fan. A spring-loaded pressure-relief 76, Fig. 2, may be fitted between the valve inlet chamber 54 and the valve outlet chamber 81 to restrict the pressure of the oil supplied to the motor to limit its speed. A pivoted, two-armed lever 58 having an adjusting screw 60 provides a means of adjusting the valve piston so that a minimum proportion of the oil is always supplied to the motor so that the motor can run at some determined minimum speed independent of the thermostat at temperatures below the corresponding minimum temperature.

Filed: 1930-06-02
Abstract: 348,417. Heating by circulation of fluids. VENTE, W., Industriestrasse, Aachen, Germany. June 2, 1930, No. 16987. [Class 64 (ii).] To maintain the circulating water of a hotwater heating system at a desired temperature in any section R of the supply or return mains, a valve d allows water from the upper hotter zone of an accumulator a to be displaced into the section R by water entering the accumulator from this section when the temperature is too low, and a valve c allows the displacement of water from the colder zone when the temperature is too high. When the water is at the desired temperature the accumulator is short-circuited. The valves may be controlled by one or more thermostats b. The accumulator may consist of a number of chambers connected in series by pipes to divide it more sharply into hot and cold zones. In a modification, the valve d may be placed in the inflow pipe which is, in this case, connected to the lower cold zone of the accumulator. The desired hot-water outflow is thus obtained by controlling the inflow. When the valve c is used to allow cold water to pass from the accumulator the displacement water enters through the hot-water outflow pipe.
