Filed: 1976-04-08
Abstract: 1524102 Cross-linked vinyl halide substituted vinyl phosphonate copolymers and foams thereof STAUFFER CHEMICAL CO 8 April 1976 [30 May 1975] 14304/76 Headings C3P and C3C A copolymer of a vinyl halide, a bis(hydrocarbyl or substituted hydrocarbyl) phosphonate and, optionally a further monoethylenic monomer is cross-linked by an amine crosslinking agent. The copolymer may be crosslinked when in the form of a film and foamed products may be obtained by inclusion of a blowing agent, e.g. an azo or hydrazide compound prior to cross-linking. Other conventional ingredients may also be included in the cross-linkable mix, e.g. plasticizers, antioxidants, stabilizers, pigments, fillers and waxes. Triethylene diamine is the preferred cross-linking agent.

[Also in Division G3] A uniform tobacco stream is obtained by trimming off surplus to a contained, removing tobacco from the container, and returning it to the stream before trimming at a rate dependant on the mass per unit length of the stream before or after trimming. In Fig. 1, tobacco from a shower 1 is transported by a conveyer 7 as a stream 2 to a groove 9 in the periphery of a rotating wheel 8 in which it is held buy suction until transferred to a conveyer 11 and converted into a paper enclosed rod by a device 12. A constant thickness of tobacco is maintained by a trimmer 10 the surplus from which passes into a container 16. The level of tobacco in container 16 is maintained constant by a photo-cell and lamp assembly 39, 40, Fig. 2, controlling the feed of shower 1. Tobacco is continuously removed from container 16 by a spiked conveyer 31 and transported pneumatically through a conduit 17 to a portion of groove 9 before it receives tobacco from conveyer 7. The rate of removal of tobacco from container 16 is made proportional to the mass per unit length of the rod or stream by controlling the speed of conveyer 31 by a measuring device 33 or 34. In a modification, the tobacco removed from container 16 is returned to stream 2, instead of groove 9, by a spiked conveyer which may be horizontal or circular. In other modifications the tobacco trimmed off is transported pneumatically to a remote container in which the level is controlled and tobacco is removed by a spiked conveyer which feeds it either to the shower or to a portion of conveyer 7 before it receives tobacco from the shower. Specification 940,136 is referred to.

Title: Distillation column reboiler control system

Filed: 1975-04-10
Abstract: 1500519 Controlling heat input to distillation column UOP Inc 10 April 1975 [11 April 1974] 14733/75 Heading C5E [Also In Division B1] In a method for controlling the heat input to the reboiler section 4a of a hydrocarbon distillation column in response to variation in the steady state operation of the column, the heat input, e.g. from a hot fluid or fuel line 19, to reboiler heater 17 is regulated in response to a signal representative of the flow rate of vapour passing into fractionation section 1 from reboiler section 4a, e.g. through the orifice plate or a venturi in riser 11, bottoms liquid being passed to and from the reboiler section to air from heater 17, e.g. via 37 and 38. A portion only of the bottoms liquid may be passed through heater 17, a second portion being passed through another heat recovery reboiler. The method may be used in the recovery of styrene from an ethylbenzene dehydrogenation system, the separation of xylene isomers, separation of aromatic/non-aromatic hydrocarbon mixtures and ethylbenzene from xylene isomers. Thus in an extractive distillation process, stock comprising 83À96% by volume aromatic hydrocarbons, 2À45% naphthenes and 13À95% paraffins is introduced at 2, sulpholane solvent containing 3À25% water esters at 2 at 260 F. at a solvent/stock mol. ratio of 3:1. Reboiler section 4a operates at 17À0 p.s.i.g. and 350 F. The temperature of bottom material flowing through 37 to heater 17 is 312 F. and sufficient fuel is fed via line 16 to produce a mixed phase in line 38 at 350 F. If there is an increase in rate of flow through conduit 37 to heater 17 resulting in a lower temperature in liquid returned via 38, the resulting decrease in flow of vapour through riser 11 is sensed by flow recorder controller 13 and valve 15 is operated to increase the flow of fuel to heater 17.

Abstract: 129,264. Koppers Co., (Assignees of Darrin, M.). June 29, 1918, [Convention date]. Paints; varnishes, and paint-vehicles.-A solvent or vehicle for paints or varnishes is prepared by subjecting crude solvent naphtha, such as results from the recovery of benzol from gas or tar, or which is obtained from the scrubbing of water gas and oil gas or other oil-bearing gases, or other liquids containing coumarone, indene, &c. or other bodies capable of polymerization, to a polymerization process, such as by heating under pressure in an autoclave, for the polymerization only of the dark-resin-forming bodies, such as dicyclopentadiene and styrolene, removing the polymerized dark-resin-forming bodies from the naphtha, and then incorporating the naphtha with a quantity of bituminous pitch. As a specific example of the preparation of a coating material, 800 lb. of bituminous pitch or coal tar pitch is heated to about 200‹ C., allowed to cool to about 150‹ C., and treated with 70 gallons of the above-mentioned solvent. Thinners, driers, fillers, &c., such as turpentine, linseed oil, China wood oil, Venetian red, red lead, zinc oleate, manganese resinate, barium sulphate, &c. may be admixed with the solvent. In the use of low boiling-point naphthas it is advisable to cut out the fraction boiling below 135‹ C., and in the case of high boiling naphthas containing naphthalene, heavy paraffins, &c., the fraction boiling above 200‹ C. should be .removed. Specification 123,806, [Class 2 (iii), Dyes &c.], is referred to.

IPC: D01F4/00
Filed: 1948-06-02
Abstract: Raw casein is dissolved in an aqueous solution of one or more water-soluble bases and treated with a solution of one or more salts of aluminium, cadmium or zinc to precipitate a casein product containing the said metal or metals.  Raw casein is defined as the protein precipitated from skimmed milk by the addition of organic or inorganic acids, by the acid produced by fermentation, by rennin or any combination of these reagents and includes unhardened casein. Acetates and chlorides are the preferred salts.  Sodium hydroxide and borate, ammonia, triethanolamine and methylamine are specified bases. The precipitated product is separated, washed and dried, when it may be hardened with formaldehyde.  The nature of the precipitate may be controlled by means of temperature, addition of rennin in the case of an acid casein, or pH adjustment.  In examples (1) lactic casein is dissolved in aqueous triethanolamine solution to give a pH of 7.95, a solution of zinc acetate slowly stirred in to form a precipitate, the pH changing to 7.18, acetic acid added to coagulate the precipitate at 40 DEG  C., the pH of the clear solution being 6.92 and the precipitate removed and washed four times with water to remove excess metal salts, pressed and dried; (2) a similar solution is prepared of pH 8.2, a solution of basic aluminium acetate in acetic acid added to give a coagulated precipitate and a pH of 4.52 for the clear solution; the precipitate is collected and washed three times to remove excess salts, pressed and dried; and in (3) rennet casein is dissolved in aqueous sodium hydroxide to give a solution of pH greater than 10.0 at 25 DEG  C., zinc chloride solution stirred in and the precipitate which forms is collected, washed, pressed and dried, the pH of the clear solution being 5.9.
