Filed: 1974-04-26
Abstract: 1468661 Air heating and circulating apparatus ANDREWS WEATHER FOIL Ltd and R W PUZYNA 26 April 1974 [11 May 1973] 22637/73 Heading F4V In an air heating and circulating apparatus a fan 19 draws air over a heater 18 and discharges the heated air through a nozzle 21. The arrangement is such that the heated air stream passes through the nozzle adjacent a part of the nozzle's internal surface and creates a depression within the nozzle which acts to draw air from outside the nozzle through the nozzle's mouth into the nozzle, the latter air being entrained into and discharged with the stream of heated air. As shown, the apparatus is supported by rods 12 in the space between a ceiling structure 14 and a false ceiling 15 formed from mineral fibre panels. The heater 18 comprises water pipes 23 threaded through fin plates 24. The nozzle 20 is of rectangular section but alternatively may be of circular section. It may be conically flared. The nozzle may have vanes in its mouth. The nozzle may additionally incorporate holes or hooded louvres in its walls to lead unheated air directly into the nozzle mouth. The entrainment of unheated air may be further aided by holes or hooded louvres in the walls of the fan casing 25.

Title: Manufacture of aromatic disulphonic acids
Inventor: GOODMAN ISAAC
IPC: C07C303/32
Filed: 1956-07-23
Abstract: Benzene-1:4- and naphthalene-2:6-disulphonic acids are prepared in the form of their alkali metal salts by heating the alkali metal salt of a benzene-1:3- or naphthalene-2:7-disulphonic acid at a temperature of at least 250 DEG  C.  The invention also includes terephthalic acid, terephthalonitrile and high molecular weight polysulphonamides when prepared from these disulphonic acids obtained as above. The heating may take place at normal or super-atmospheric pressure, preferably in an atmosphere of carbon dioxide or nitrogen. The reaction will take place above 250 DEG  C., but in the absence of a heavy metal catalyst a temperature above 375 DEG  C. is generally needed; an upper limit of 600 DEG  C. is mentioned. Catalysts containing mercury or chromium, e.g. the metal or its oxide, are preferred.  The potassium or preferably the sodium salt may be used and the free acid may be obtained from the crude disulphonate by contacting with a cation-exchange resin.  In examples: (1), (6), (7), (8), (9) disodium and (2) dipotassium benzene m-disulphonate is heated under various conditions to give the p-disulphonate; (3), (4), (5) disodium naphthalene-2:7-disulphonate is heated under various conditions to give the 2:6-disulphonate.  In some cases symmetrical trisulphonic acids are obtained as by-products.

Abstract: 913,846. Induction heating. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 2, 1959 [July 5, 1958], No. 22755/59. Class 39 (3). [Also in Groups XII and XXX] In an arrangement for inductive heating of workpieces, a movable slide path, which supports and transports the workpieces in an uninterrupted order of succession through an inductor, is coupled with a drive which causes the slide path to oscillate longitudinally with so high a speed in the reverse direction that the insertion of the workpieces inhibits them from following the movement of the slide path in the reverse direction, and simultaneously the workpieces are subjected to a feeding force which transports them with the desired speed through the inductor. As shown in Fig. 1, the movable slide path comprises two tubes 5 traversed by a coolant and secured to a support 3 which, under the action of lever 11 driven by electric motor 9, moves slowly to the right, transporting the workpieces 6 through the inductor 1 and rapidly to the left during which the workpieces remain stationary relative to the inductor. Alternatively, the slide path comprising a gutter 12, Fig. 4, may be supported by blade springs 14, 15 secured to frame 2, or, as shown, to inductor 1, the drive being provided by an electromagnet 13 acting upon armature 18 secured to spring 15. In further embodiments, the slide path, which may have a wear-resistant coating, slopes downwards in the transport direction and is caused to perform substantially sinusoidal axial oscillations at high frequency.

Title: Process for the manufacture of chlorinated aliphatic hydrocarbons
IPC: C07C17/10
Filed: 1955-08-08
Abstract: The invention comprises a method of chlorinating aliphatic hydrocarbons having at least 2 carbon atoms, saturated or monounsaturated, and, if desired, partly chlorinated, with chlorine, if desired in admixture with an inert gas, by admixture with already reacted product circulating in the reactor, in the proportion by volume of less than one to three, the reaction being carried out without any substantial supply or withdrawal of heat, the fresh gas having such a temperature just prior to admixture that the resulting temperature is between the starting temperature for the reaction and the decomposition temperature of the chlorination products, a proportion of the product being withdrawn at the same rate as fresh gas is introduced.  The chlorination products may be cooled, and those not thereby condensed recycled to give a higher proportion of more highly chlorinated compounds.  Part of the reactants may be sprayed into the reactor in liquid form.  In examples: (1) a mixture of chlorine and ethane is passed at 25 DEG  C. into the reaction vessel and the reaction carried out at 390 DEG  to give mainly ethyl chloride with some dichlorethanes; (2) to obtain a higher yield of dichlorethanes, the products of (1) are cooled to 6 DEG  C. and the uncondensed products recycled, ethane being added as it is consumed; (3) chlorine and propane are introduced at 250 DEG  C. and react at 360 DEG  C. to give mainly n-propyl and isopropyl chlorides and 1:2-dichloropropane; (4) ethylene and chlorine are passed in at 25 DEG  C. and react at 345 DEG  C. to give mainly vinyl chloride (which is separated and the unreacted gas re-cycled), and chlorinated ethanes and ethylenes; (5) chlorine and vinyl chloride are passed in at 25 DEG  to react at 390 DEG  C. to give dichlorethylenes and higher boiling chlorinated ethane and ethylene mixture; (6) ethyl chloride and chlorine are passed in at 60 DEG  C. and react at 370 DEG  C. to give mainly dichlorethane with some higher boiling chlorinated ethane and ethylene mixture, and vinyl chloride; some ethylene and hydrogen chloride are produced; (7) the procedure of (6) is varied to give a reaction temperature of 350 DEG  C. and an increased proportion of vinyl chloride.  In all cases the chlorine is practically entirely consumed.  The apparatus described in the parent Specification may be used.
