Title: A process for preparing terephthalic acids
Filed: 1953-11-05
Abstract: In a process for preparing terephthalic acid, para-diisopropyl benzene is oxidized by means of oxygen or a gaseous mixture containing free oxygen, such as air, in a medium consisting mainly of an organic acid in which para-diisopropyl benzene is soluble and in the presence of a catalyst comprising a manganese compound together with either a cobalt compound or a barium compound or both a cobalt compound and a barium compound.  Organic acids mentioned include saturated fatty acids with from 2 to 8 carbon atoms, e.g. acetic, propionic and butyric acids.  Preferred salts of manganese, cobalt and barium for use as catalysts are those of the same acids as constitute the solvent or naphthenates may be used.  Further para-diisopropyl benzene may be added during the reaction.  The process may be carried out continuously, further catalyst being added during the reaction.  The reaction may be carred out at atmospheric or superatmospheric pressures and vapours leaving the reaction mixture may be partially or completely condensed and recycled.  In examples terephthalic acid is obtained by passing oxygen into a mixture of para-diisopropyl benzene, propionic acid and manganese and cobalt acetates at elevated temperature, low boiling products, e.g. aldehydes and esters, being distilled off during the reaction and the precipitate separated and worked with alcohol (1); in a similar process some terephthalic acid is removed intermediately (2); terephthalic acid is obtained by passing air into a heated mixture of diisopropyl benzene, glacial acetic acid and manganese and cobalt acetates in a V2A steel autoclave at elevated pressure, so as to maintain an elevated pressure (3); in a process similar to (1) fresh diisopropyl benzene and catalyst is added during the reaction and terephthalic acid is filtered off (4); in a similar process butyric acid is employed (5); and in a process similar to (1) para-diisopropyl benzene dissolved in acetic acid is treated in a stainless steel autoclave at elevated temperatures with air at various elevated pressures in the presence of various proportions of cobalt and manganese acetate catalysts.  The rates of para-diisopropyl benzene consumption and terephthalic acid production in examples (4) and (5) are expressed in graphs.

Filed: 1946-10-15
Abstract: 641,788. Electrode materials and processing. PHILIPS LAMPS, Ltd. Oct. 15, 1946, No. 30701. Convention date, Jan. 15, 1943. [Class 39 (i)] A method of manufacturing a discharge tube which contains a thin layer of carbon, i.e. of the order of 0.1 mm. or less in thickness, and in which the active layer of the cathode is obtained by the heating and decomposition of an alkaline earth carbonate, comprises vaporizing a material such as barium simultaneously with the decomposition of the carbonate so as to absorb the carbon dioxide evolved and to prevent it from attacking the carbon layer. The thin carbon layer may comprise a shield or electrode, e.g. the heating element of an indirectly cathode applied on a ceramic body. A second gasabsorbing material may be vaporized after the exhaustion and sealing-off to absorb other residual gases; alternatively, one gas-absorbing material only may be used which is vaporized in two portions. The gas-absorbing material is arranged in a holder secured to a lead-in conductor. The Specification as open to inspection under Sect. 91 states that the gas-absorbing material may be vaporized immediately before the decomposition of the carbonate. The carbon layer when used as a heating element for an indirectly heated cathode may be applied outside or inside a ceramic body. This subjectmatter does not appear in the Specification as accepted.

Abstract: 694,664. Gas-heated radiators. RADIATION, Ltd. Oct. 9, 1951 [Dec. 18, 1950], No. 30745/50. Class 51(i) In a gas heated radiator of the kind used in indus trial drying chambers and comprising a front radiating panel, a refractory back spaced from the panel and a burner at one end of the space between the pane and the back, the outlet end of the space is at a higher level than the burner wher the radiator is facing in any direction between the horizontal and the downward ly directed vertical.. The front radiating panel c and the refractory back b form a combustion space which tapers towards the combus tion products outlet m. The burner nipples f are fed by a branch pipe accommodated in an air inlet opening d at the wide end of the combustion space. A short flue h extends laterally from the rear of the casing across the width of the heater, narrowing to its outlet aperture i. The position of the burner nipples f is such that when the radiator is facing directly downwards, the outlet m is above their level, so that, with the assistance of the flue h, smothering of combustion at the burner is avoided. Specification 454,328, [Group XI], is referred to.

Title: Adaptive closed loop control
IPC: G05B6/02
Filed: 1967-07-05
Abstract: 1,135,508. Adaptive automatic control. INTERNATIONAL BUSINESS MACHINES CORP. July 5, 1967 [July 5, 1966], No.30856/67. Heading G3R. In an adaptive closed-loop control system, gain is automatically controlled in dependence on the difference between a signal proportional to error and a signal proportional to rate of change of the error or the controlled variable. Gain is thus varied in direct proportion to the error and in inverse proportion to the rate of change to give a proportional plus integral control effect. In Fig.l, deviations of a controlled variable are detected by a thermocouple 1 the signal from which is compared at 9 with a signal from a set point controller 5 so that any error is effective for corrective purposes through an amplifier 12. The gain of the system is automatically controlled by adjusting a feedback potentiometer 15 in dependence on the output of a differential amplifier 18 to which is applied, at 19, a signal corresponding to the error, and, at 20, a signal, equivalent to the rate of change of the variable, which is obtained from thermocouple 1 through a high-pass filter 21 and a rectifierintegrator 22. The rate of change signal may alternatively be obtained from the error signal in a similar manner so that high frequency disturbances caused by adjustment of the set point are catered for. The high pass filter has top cut to eliminate the effect of noise. A photo-sensitive resistor may be employed instead of potentiometer 15. In a modification, the output of amplifier 18 is applied to an analogue to digital converter controlling the switching of a plurality of feedback resistors associated with amplifier 12. A digital computer may be used instead of a high-pass filter and rectifier-integrator to derive the rate of change signal.

Abstract: 762,053. Refrigerating. SATRAMETAL SOC. ANON. Oct. 27, 1954 [Oct. 27, 1953], No. 30948/54. Class 29. In a vapour expulsion unit for a continuous cycle absorption system of the inert gas type comprising a vertical heating tube 1 surrounded by a boiler 3, strong solution from the liquid heat exchanger flows downwardly through an auxiliary boiler 4 heated by the main boiler 3 to a reaction column 6 from which the solution passes into a bubble pump 2 located within boiler 3 and in direct heat exchange relation with the heating tube 1. The pump discharges into a pipe 7 which is a laterally offset extension of the boiler 3. Vapour from auxiliary boiler 4 passes into pipe 5 leading to the condenser. Vapour from the pipe 7 is hotter than the vapour from boiler 4 and is led by pipe 8 into the top of boiler 4 where it is analyzed . The top of pipe 5 forms an enlarged finned rectifier chamber 9 in which is a cup 10 in heat conducting relation with the condenser and communicates therewith. As the vapour passes through the cup, absorbent condenses and drains through hole 13 back to the boiler.
