Title: Process for the control of the temperature in chemical reactors by the indirect exchange of heat by means of water under pressure
Inventor: SPAENIG HERMANN
IPC: B01J19/00
Filed: 1960-06-30
Abstract: 952,183. Heating and cooling systems for chemical reaction vessels. BADISCHE ANILIN- & SODA-FABRIK A.G. June 30, 1960 [July 1, 1959], No. 22887/60. Heading F4U. A heat transfer liquid, e.g. water, circulating through a system including a chemical reactor 6 and a main vessel 1, is maintained at a pressure sufficient to prevent any substantial formation of steam bubbles in the liquid chambers around the reactor. In the apparatus shown, the temperature of the circulating water is regulated by a thermally responsive element 19 which controls the operation of a cooling coil 17 and a heating coil 18 in the vessel 1 to maintain a constant water temperature in the system. Above the vessel 1 is an auxiliary vessel 2 connected with the vessel 1 by a narrow pipe 3 permits the water in the vessel 2 to be maintained at ambient temperature by a small cooling coil 10. Pressure of a gas such as nitrogen in a vessel 11 is transmitted to the space above the water in vessel 2 and hence to the circulating water throughout the system. The gas pressure is maintained constant at a pressure sufficient to prevent the formation of steam bubbles by a regulator 12. The water level in the vessel 2 is maintained constant by a float 14 which regulates make-up water supply and discharge valves 15, 16 connected into the water circulating system. In the process described for carrying away the heat of an exothermic chemical reaction, the water flowing in the reactor jackets 5 serves to heat up the reacting substances at the inlet end of the reactor and at the same time to withdraw heat generated in the middle and at the outlet end of the reactor

Abstract: 623,567. Valves. TRICO PRODUCTS CORPORATION. Aug. 1, 1946, No. 22993. Convention date, Aug. 10, 1945. [Class 135] [Also in Group XXVI] A control valve for a suctionoperated motor has a ported valve seat over which slides a soft-rubber valve body having one or more recesses in its operating face. The valve body 37, Fig. 3, fits loosely in a metal housing 39, the projections 41 interlocking with the slots 42, and slides through the guide 44, Fig. 5, over the seat 38 on the cover 24 of a vehicle windscreen-wiper motor. In the seat are ports 50, 54 connecting via the nipple 57 with a suction reserve tank and through a check valve with the intake manifold of the vehicle's engine, and ports 51, 52, 53, 55 of which the port 55 is connected to a windscreen-washer pump. When the control valve is in the motor-working position determined by the stop 46, a recess 48 in the valve body connects the ports 50, 51, so that suction is applied via a port 30 in the seat 29 of an automatic rotary valve mechanism, a groove 60 in the rotary valve 26 and a port 31 to the left-hand side of a chamber in which moves a vane 35. The right-hand side of the chamber is connected to atmosphere via a port 34, a passage 33, ports 53, 52, connected by the recess 49 and a port 32 in the rotary-valve seat. At the end of the movement of the vane to the left, a kicker-element 27, moving between the ears 28 on the rotary valve, is turned by the motor shaft 3 to an over-centre position from which it is snapped by the spring 27<SP>1</SP> to move the valve 26 to connect the port 32 to suction and reverse the movement of the vane. To stop the motor, the control valve is moved by the flexible wire 19 until the recess 49 connects the ports 53, 54, and suction is applied to the left-hand side of the chamber to move the vane until the disc 36 closes the port 34. In this position of the control valve the recess 47 is opposite the suction port 50 and prevents the formation of a pimple in the soft rubber. When the control valve is moved, against the plunger 63, so that the recess 49 connects the ports 54, 55, suction is applied via nipple 58 to operate the washer pump. Specification 597,504, [Group XXIII], is referred to.

Patent GB-1074280-A (GB)
Title: Delustred polyesters
IPC: D01F6/62
Filed: 1966-05-25
Abstract: As a delustrant for polyesters, there is used a calcined kaolinite having the empirical formula Al2O3.2SiO2 having the hexagonal platelet structure, and being in the form of particles which have equivalent spherical diameters of 0.2 to 7 microns.  The delustrant may be made by (a) calcining kaolinite at 500 DEG  to 1000 DEG  C. until differential thermal analysis shows removal of an endothermic peak at 500 DEG  C. and retention of an exothermic peak at 1000 DEG C., or (b) calcining kaolinite at above 1000 DEG  C. until differential thermal analysis shows removal of both an endothermic peak at 500 DEG  C. and an exothermic peak at 1000 DEG  C.  After calcination, the hot delustrant may be quenched in an aqueous slurry containing tetrasodium pyrophosphate (as dispersion agent) and the slurry fractionated to give the desired delustrant particle size by a series of centrifugation and gravitational settling operations.  The desired slurry fraction may then be flocculated with sulphuric acid and washed until all soluble salts are removed, following which the delustrant may be spray dried.ALSO:Fibre- and film-forming polyesters are delustered by incorporating into them 0.1 to 10% by weight of calcined kaolonite; the latter having the empirical formula Al2O3.2SiO2, having the hexagonal platelet structure and being in the form of particles which have an equivalent spherical diameter of 0.2 to 7 microns.  Any acidity introduced by the kaolinite may be neutralized (e.g. with sodium acetate).  Titanium dioxide may be used as an additional delustrant.  Examples describe the manufacture of delustered polyesters by (a) feeding bis - (2 - hydroxyethyl) terephthalate (possibly together with a little sodium bis-(2-hydroxyethyl) - 5 - sulphoisophthalate) and a dispersion of calcined kaolinite and titanium dioxide in ethylene glycol to a continous polymerisation apparatus; (b) tumbling flakes of polytrimethylene terephthalate containing titanium dioxide with calcined kaolinite; (c) polymerising pivalolactone in the presence of titanium dioxide and tumbling the resulting polyester powder with calcined kaolinite.

Abstract: Water-soluble mixed cellulose ethers containing cyanoethyl groups and alkyl groups are produced by dissolving a water-insoluble, alkali-soluble cyanoethyl ether of celluose having 0.01 to 0.5 cyanoethyl group per anhydroglucose unit of the cellulose in a dilute aqueous solution containing 3-6 mols. of an alkali metal hydroxide or 1-2 mols. of a quaternary ammonium hydroxide per anhydroglucose unit of the cellulose and reacting the solution obtained with 0.3-3 mols. of an alkylating agent per anhydroglucose unit originally present in the cellulose of the water-insoluble, alkali-soluble cyanoethyl ether of cellulose, the alkylating agent containing one or more alkyl groups each having not more than four carbon atoms.  The alkylating agent is preferably a dialkyl sulphate, e.g. dimethyl, diethyl or methylethyl sulphate or a mixture of dimethyl and diethyl sulphates. Alkyl halides such as ethyl chloride may be used as alkylating agents.  The alkylation is preferably carried out at 15-30 DEG  C. In an example, 1 kg. of a water-insoluble, alkali-soluble cyanoethyl ether of cellulose containing 0.26 cyanoethyl group per anhydroglucose unit of the cellulose prepared in a described manner is soaked in 10 litres of water, 4 litres of water containing 0.75 kilogram of sodium hydroxide is added and the mixture diluted with water to 20 litres.  576 mils. of dimethyl sulphate are added and mixture stirred for 4 hours at 25 DEG  C.  The mixture is neutralized with a 15 per cent aqueous solution of hydrochloric acid and dialized in a regenerated cellulose casing by means of a continuous stream of softened water until free from electrolytes.  The solution is then concentrated to a paste by distillation under reduced pressure and the mixed ether precipitated by the addition of ethyl alcohol, filtered, washed with alcohol and air dried.  Examples are given of the preparation of cellulose ethers by similar methods using aqueous solutions of dimethyldibenzyl - ammonium hydroxide in place of sodium hydroxide and also an example in which ethyl chloride is used as the alkylating agent in conjunction with sodium hydroxide in an autoclave.  The compositions of the products obtained in the examples are given.  Aqueous solutions of the mixed ethers are stable on long standing and not gelatinized by heating.  They are compatible with aqueous solutions of anionic and cationic surface-active substances and with non-ionic detergents.  Aqueous solutions of the mixed ethers may be used as sizes for textile yarns.  Specifications 588,751 and 636,295 are referred to.
