Abstract: A process for preparing a bis-(hydroxyaryl) compound having the formula <FORM:0785079/IV (a)/1> wherein R1 and R2 represent the same or different saturated or unsaturated monovalent aliphatic, cycloaliphatic, aromatic or heterocyclic radicals with the provision that either R1 or R2 but not both may also represent a hydrogen atom and the symbols Ar and Ar1 represent the same or different aromatic nuclei by the acid catalysed condensation of a phenolic compound comprises reacting said phenolic compound with said carbonylic compound in a mol. ratio of at least 5:1 and in a plurality of successive reaction stages maintained temperatures between about 20 DEG  and about 110 DEG  C., the reactants introduced into the first reaction stage comprising substantially all of said phenolic compound but only a part of said carbonylic compound and the remainder of said carbonylic compound being introduced into at least one subsequent reaction stage.  Suitable phenolic starting material should have at least one replaceable hydrogen attached to a nuclear carbon atom and may have such substituents as alkyl, cycloalkyl, aryl, alkaryl and aralkyl groups, and include phenol, the cresols, xylenols, thymol, carvacrol, 2,4-dimethyl-3-ethylphenol, o- and p-phenylphenol, the naphthols and phenanthrol.  The carbonylic starting materials are aldehydes and ketones of the general formula R1R2CO, where R1 represents any aliphatic, cycloaliphatic, aromatic or heterocyclic monovalent radical, e.g. pyridyl and R2 represents a hydrogen atom or a monovalent radical as defined under R1, e.g. dimethyl, dibutyl and methyl amyl ketones, propionylphenone, acetophenone, acetaldehyde, benzaldehyde and acetyl pyridine.  Catalysts mentioned include hydrogen chloride, sulphuric, phosphoric, hydrobromic, hydrofluoric, nitric and p-toluene sulphonic acids, dimethyl sulphate, sulphur dioxide, boron trifluoride and complexes thereof, aluminium chloride, sulphonyl chloride and phosgene.  Promoters may be employed such as methyl and ethyl mercaptans, thiophenols and mercapto-substituted aliphatic monocarboxylic acids.  Solvents mentioned include aromatic hydrocarbons such as xylene, toluene and chlorinated hydrocarbons. 2,21 - Bis - (4 - hydroxyphenyl) propane is obtained by reacting phenol and dimethyl ketone in two reactions in series in the presence of hydrogen chloride and methyl mercaptan, only part of the ketone being introduced into the first reactor and the remainder with the second.  In the drawing (not shown) an apparatus comprising two reactors and distillation columns is shown.  Specifications 735,215 and 735,216 are referred to.

Abstract: 1,133,022. Evaporators; removal of volatile material from polymerization mixtures. PLASTUGIL. I May, 1967 [6 May, 1966], No: 20068/67. Heading B1B. Volatile material is evaporated from a viscous polymerization mixture in an apparatus comprising an enclosure in which are mounted, in parallel, four rotatable cylinders 7 each of which is tangential to the adjacent cylinders thereby forming an inner chamber 8 in which the vapours of the volatile material are liberated by inflation of thin layers of the liquid mixture on the lateral surfaces of the cylinders. Heating-medium may be passed through the casing 4, and may also be passed through the cylinders. The liquid mixture is introduced into the apparatus through passages 10 at one end of the enclosure, and travels along between the cylinders and the inner wall 9 of the enclosure. The devolatilized material is discharged through openings associated with the journals at the other end of the apparatus. The vapours are withdrawn from chamber 8 through an outlet at the same end of the apparatus, which may be connected to a vacuum pump. The cylinders may be screwthreaded, fluted or grooved.

Title: Process for preparing gas mixtures containing hydrogen and carbon monoxide
Inventor: HAAR LEONARD WILLEM TER
Filed: 1965-05-12
Abstract: A combustible gas is made by partial combustion in a reactor under superatmospheric pressure of a hydrocarbon material, the material comprising, at least in part, a liquid hydrocarbon admixed with water which comprises not more than 4% by weight of the total fuel intake (i.e. liquid hydrocarbon and suspended solids, if any), before admission to the reactor.  Two embodiments are described. In one, Fig. (not shown), a measured amount of water is injected into a liquid hydrocarbon line, and the mixture is pressurized to 60 to 160 atmospheres and may be preheated to not more than 350 DEG  C. in a heat-exchanger. The mixture enters the reactor through an atomizer. In the other embodiment, the fuel includes soot, and is made by treating the aqueous suspension of soot from a gas-washing step with a hydrocarbon oil to form oil-soot aggregates which are mixed with further oil to form a soot-in-oil suspension containing not more than 4% water by weight.

Abstract: 1,066,282. Aircraft indicators. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. April 28, 1965 [May 15, 1964], No. 20359/64. Heading B7W. [Also in Division H3] In navigational equipment for an aircraft or aircraft flight simulator, the outline of an imaginary aircraft is projected on to the windscreen from a cathode-ray tube and the pilot is required to follow the imaginary aircraft to maintain course. The imaginary aircraft is seen in perspective, and is represented by five lines corrsponding to the two leading edges, two trailing edges and the fin of a delta wing. The co-ordinates of the points at the ends of the lines are computed from the aircraft flight data, from preset signals corresponding to the dimensions of the imaginary aircraft, and variable signals corresponding to the roll, pitch and yaw of the imaginary aircraft, i.e. the command signals, relative to the actual aircraft axes. The image is rotated in accordance with the roll angle of the actual aircraft, and may be produced on the cathode-ray tube as a television image, or as described, by deflection of the electron beam to form the five lines (see Division H3), and a horizon line. For landing, the image also contains two lines representing the edges of a runway, the distance from the touchdown point being represented by the arc of a circle centred on the base of the fin of the imaginary aircraft, the length of the arc being a measure of the distance. The image may also contain a speed error indicator, and in digital form the altitude and air-speed (Fig. 7, not shown).

In a heat exchanger in which fluid flowing through parallel tubes is in heat exchange relationship with fluid flowing over the tubes in a direction generally parallel to the tube axes, deflector bodies having cross-sections which alternately increase and decrease along their axes are arranged amongst the tubes and spaced from them with their axes parallel to the tube axes, the lengths of increasing cross-sectional area of some of the deflector bodies being abreast of lengths of decreasing cross-sectional area of other deflector bodies. As shown, the deflector is hollow and surface 7 is generated by revolution about axis 9 which is in the direction of fluid flow varies periodically in diameter between a minimum as at planes 10 and a maximum as at planes 11. The lengths 12 between planes are about onefifth the axial length of lengths 13. The tubes may be helically grooved both internally and externally (see Fig. 1, not shown), or be formed externally with some form of extended surface area, e.g. small longitudinally extending fins or longitudinal serrations or grooves. The deflector bodies may have internal and external extended surface areas. In an embodiment the deflector bodies may be adapted to allow fluid to flow therethrough parallel with fluid flowing through the tubes. In an alternative embodiment a deflector body is arranged within each tube (Fig. 1, not shown). Figs. 3 to 7 (not shown), illustrate various arrangements of the tubes and deflectors.

Title: Process for concentrating formic acid by distillation
IPC: C07C51/46
Filed: 1945-08-09
Abstract: In the dehydration of dilute formic acid aqueous solutions by distillation in presence of n-propyl alcohol or iso-propyl ether as entrainer, the dilute solution is first concentrated by distillation to obtain a residue comprising a constant boiling mixture of formic acid and water which is then subjected to further distillation in presence of the entrainer.  When the distillation is carried out at normal pressure the residue boils about 107 DEG C. and contains approximately 77.5 per cent. formic acid; the further distillation is carried out by adding 300-600 pts of entrainer per 100 part residue the azeotrope distilling over at about 75-76 DEG C. in the case of n-propyl alcohol and at 61-62 DEG C. in the case of isopropyl ether.
