Title: Sulphonation of organic liquids
Inventor: ELTENTON GEORGE CHARLES
IPC: C10G67/08
Filed: 1957-11-12
Abstract: The invention comprises a process for the sulphonation of an organic liquid, by pumping the liquid through a flow mixer of a type in which the flow of the liquid to be sulphonated causes a reduction of pressure by which the gaseous sulphonating agent viz. sulphur trioxide in an inert gas is drawn in and then entrained by the liquid flow.  Organic liquids which may be sulphonated are, e.g. alcohols, fatty oils, fatty acids or hydrocarbons such as mineral lubricating oils, C8-C20 olefines; alkyl benzenes and toluenes containing 8-18 carbon atoms in the alkyl group, or alkyl polycyclic aromatic hydrocarbons such as alkylated naphthalenes, anthracenes, and phenanthrenes.  The sulphur trioxide used may be generated by heating liquid sulphur trioxide, distilling oleum, or by the oxidation of sulphur dioxide.  The sulphur trioxide should contain an inert gas as a diluent preferably 97 to 75 parts by volume of the inert gas per cent of the gas mixture.  Suitable inert gases are air, carbon dioxide, nitrogen and sulphur dioxide.  The sulphonation is preferably carried out between 35 DEG  and 90 DEG C., the contact time between the gaseous stream and the organic liquid in the flow mixer being very short.  Types of flow mixer suitable for use in the process are eductors, injectors and jet mixers through which the flow of liquid results in a reduction of pressure at some particular point in the flow mixer, and it is at this point that the source of the gaseous sulphonating agent is connected.  The ratio of the volume of gas entrained to the liquid flowing through the flow mixer may be between 1 : 1 and 60 : 1.  The organic liquid to be sulphonated may be recycled, preferably in the ratio of at least 15 vols recycled liquid per vol of fresh organic liquid, in order to permit more efficient cooling and entrain further sulphonating agent.  A centrifuge may be incorporated in the liquid recycle system. Examples are given of the sulphonation of a white hydrocarbon oil, and a mineral lubricating oil. Specification 855,775 is referred to.

Title: Process for producing flavin-adenine dinucleotide
IPC: C12P25/00
Filed: 1966-08-09
Abstract: Flavin-adenine dinucleotide (F.A.D.) is prepared by culturing am icro-organism capable of producing a 51-purine nucleotide and belonging to the genus Brevibacterium, Micrococcus, Corynbacterium or Flavobacterium in an aqueous nutrient medium under aerobic conditions at a temperature of 20-40 DEG  C. and a pH of 5.5-9 and recovering the F.A.D.  With certain strains of the above genera it is necessary to add specific nutrients, e.g. purine bases or nucleosides or natural substances containing them. When mutants having specific nutrient requirements are used these specific nutrients must also be added to the culture medium, such nutrients including, for example, aspartic acid, glutamic acid, threonine, methionine, biotin, thiamine and cobalamin.  Other products obtained from the process include inosinic-, adenylic-, guanylic- and xanthylic-acid.  Specific microorganisms referred to are Brevibacterium ammoniagenes, Micrococcus glutamicus, Brevibacterium linens, Micrococcus freudenreichii, Corynbacterium acetoglutamicum, Corynbacterium hydrocarboclastus, Flavobacterium arborescens and Flavobacterium devorans.

[Also in Division C3] Articles having a foamed case with integral unfoamed surface skins are made by injecting an unfoamable synthetic resin into a mould and then injecting a synthetic resin containing a blowing agent to within the unfoamable resin under such conditions that foaming is prevented in the mould, the moulding is allowed to cool until it is below the temperature at which foaming would take place under atmospheric pressure, removed from the mould and shaped under such conditions of heat and pressure that the blowing agent is activated to foam the core of the moulding. The unfoamable resin may be polypropylene, polyvinyl chloride polyethylene, polybutene, poly-4-methyl pentene-1, polymers of styrene or methyl methacrylate, or polyethylene terephthalate. The foamable resin may be the same as or different from the unfoamed resin. The moulding may be shaped by vacuum forming and only selected areas may be foamed by applying pressure to the areas which are not to be foamed while the moulding is heated to the foaming temperature. A second amount of unfoamable resin may be injected into the mould after the foamable resin.

The mixture of resins R 1  and R 2  and the carrier fluid introduced at 4 flow vertically upwards at a decreasing speed due to the widening of the flow area and penetrate in a separation zone 5 without turbulence. The fluidizing medium is liquid and is introduced at 6 through a perforated toroidal member of distributing floor. The heavier resins R 2  move downwards into the lower portion 2 of the chamber 1 and are removed at 7. The lighter resins R 2  move to a zone 8 above the separation zone 5 and are discharged at 9. The fines of the heavier and lighter resins are discharged at 10 and 11 respectively. Liquid overflows at 12. In a modification, the upper-portion of the apparatus defining the zone 8 has a frustoconical configuration. In a further modification, Fig. 3, the upper portion comprises two superposed cylinders of different diameters interconnected by a frusto-conical portion, the upper cylinder 15 forming a buffer zone to decrease the fluidizing rate. In a further modification, the upper end of the chamber 3 is surmounted by a baffle to reduce turbulence.

WESTERN ELECTRIC CO Inc 5 Aug 1971 [7 Aug 1970] 36773/71 Headings H3T and H4P A circuit, particularly for producing returnto-zero signals from bipolar signals comprises means 10 for producing complementary first and second data signals (Fig. 2a, not shown) from the input signals, means for applying the first data signal to one input of each of two differential amplifiers (amplifiers 13, 15 and 17, 18) and the second data signals to the other inputs (e.g. via emitter followers 22, 24, 23 and 26). Sampling pulses (Fig. 2b, not shown) are applied at 30 to enable the amplifiers when the data signals have established values and load resistors are so connected to the outputs that the data pulses produce symmetrical changes about the voltage level during the non-sampling intervals. As shown, input signals at 8 are sampled and set a bi-stable circuit in unit 10 to provide the complementary signals and the outputs from the amplifiers are combined in a "balun" 36-44. The output pulse width may be varied by varying the sampling pulse width. The circuit balances out spurious feed-through.
