Abstract: 1,172,385. Ultrasonic inspection devices. DR. J. U. H. KRAUTKRAMER GES. FUR ELEKTROPHYSIK. 24 Nov., 1966 [1 Dec., 1965], No. 52647/66. Heading H4D. In a pulse-echo system for the ultrasonic inspection of tubular specimens, a probe is arranged inside the specimen for relative rotation about the axis of the specimen. In the Fig. 3 embodiment, probes are retained by springs in peripheral holes 14b of a probe-holder rotated by motor 13. The holder is traversed axially relative to specimen 10, guided by member 11 and sprung rollers 15. Under centrifugal forces the probes move against the retaining spring action and contact the specimen wall through a film of coupling fluid on the wall. In a second embodiment (Fig. 2) a pair of sealing discs (16, 17) disposed one each side ef the probeholder close off a length of the specimen to define a chamber for coupling fluid and also act as guides for the axial traverse of the probeholder, and the probes are fixed relative to the holder. Centrifugal effects cause any air bubbles in the fluid to collect in the axis of rotation, where they do not disturb the inspection. The probe-holder may, alternatively, be rotated by a turbine driven by coupling fluid flowing through the chamber.
Patent GB-527555-A (GB)
Abstract: 527,555. Cracking oils catalysts. KELLOGG CO., M. W. April 14, 1939, No. 11381. Convention date, April 15, 1938. [Classes 1 (i) and 32] Hydrocarbons are cracked in the vapour phase in presence of catalysts by vaporizing the hydrocarbon, mechanically mixing the catalyst therewith to form a fluid suspension and passing the suspension through a reaction zone, separating the vapours from the catalyst and condensing them. The catalyst is regenerated by heating it in suspension in a stream of flue gas containing oxygen, e.g. air and the flue gas is used to return the catalyst to the mixing chamber. Oil from a tank 1 is passed through a preheater 4 into a vaporizing coil 5 and separator 8 from which tar is withdrawn through line 9 and re-cycled through line 13 if desired. The vapours are superheated in coil 16 to 925‹ F., and mixed in a mixer 23 with catalyst supplied from a hopper 27, The mixing device may be of the type described in U.S.A. Specifications 1,553,539 and 2,102,330. The suspension thus obtained is pumped through reaction coils 29 which are heavily insulated or heated to maintain the reaction temperature into a separator 30 where the catalyst particles are separated, the vapours passing off through line 34, heat exchanger 4 and cooler 35 to a receiver 36 where the condensate is separated from gases. The separated catalyst is fed by a screw conveyer 33 to regenerating coils 46 through which it is blown by flue gas supplied from a holder 40 and lines 41, 43. The temperature in the coils 46 is maintained at 600- 1200‹ F. and regeneration is effected by introducing air fed by a blower 48 through lines 49, 50 into the coil 46 at a plurality of points. The regenerated catalyst is separated in a receiver 27<SP>1</SP> and recycled to the hopper 27 while the flue gas is re-cycled through line 54 to the holder 40. A modified form of apparatus is also described in which the catalytic conversion and regeneration of the catalyst is carried out in bulk reaction chambers instead of in pipe coils. Catalysts specified comprise alumina deposited on silica gel, diatomaceous earth, bauxite, nickel and like metals on carriers comprising clay gels or pumice.

The water and gas inlets in the T-mixer have bores facing each other that are unrestricted, although' the gas inlet has a length of tubing of restricted bore size connecting it to the mixing zone. There is a turbulator disposed in and extending along a length of the mixing line. Valve 48 maintains a constant pressure drop in gas line 47 and valve 26 maintains a constant flow rate in the water line. A check valve 28 prevents reverse flow of carbon dioxide gas therethrough whilst threeway venting valve 27 vents any gas leakage past the closed check valve. A level control 54 controls valves 48 and 27 to maintain the liquid level in the tank between predetermined limits. A refrigerant line 12 surrounds the tank and is connected to the water line and syrup lines 30. Valve 26 also controls the volumetric rate of water flow based on the refrigerating capacity of the refrigerating means. A syrup supply tank 40 is connected to the mixing type faucet 42 by a line 41. The motor 32 for the refrigerant is under the control of a thermostat 39 which is disposed in heat transfer relationship to the water coil 16 so that as soon as water is admitted to the coil the refrigeration system promptly starts. Faucet 24 provides a still drink.

The delaying substance 35 is preferably an aqueous solution of ammonium nitrite or ammonium chloride having melting points of -17À4 and -15À8‹ C. Refrigerant is supplied to a cooling coil 14 by a compressor 12, the resulting cooled air being circulated in the direction of the arrows by a fan 21. At fixed times, a time switch 24 disconnects the compressor 12 and fan motor 20 and connects an electric heater 26 for de-frosting. The resulting water passes through a funnel 28 and is evaporated by the heat of the compressor. The compressor 12 is controlled by a bulb 39 connected to a thermostat 38.
