Title: A method of cracking hydrocarbons
IPC: C01B3/38
Filed: 1963-07-18
Abstract: In a method of catalytically cracking hydrocarbons with oxygen or oxygen-containing gases with steam and/or carbon dioxide at a pressure between 5 and 40 atmospheres, the product gases are passed through the tubes of a waste heat boiler at at least 12 metres/second, and preferably at over 17 metres/second. Displacement bodies, e.g. iron rods or pipes, are suspended in the tubes to restrict the cross section and produce the required gas velocity. The invention prevents deposits, e.g. of carbon, SiO2, Al2O3 and Fe2O3, on the tubes which occur at lower velocities.  In an example, refinery gas and butane was preheated with steam to 550 DEG  C. and after mixing with air and oxygen cracked at 900 DEG  C. over a nickel-containing catalyst, the product gases being passed downwardly through a boiler at 17 metres/sec.

Abstract: 754,805. Electromagnetic brakes. GENERAL ELECTRIC CO. Oct. 6, 1954 [Oct. 20, 1953], No. 28799/54. Class 103 (1). [Also in Group XXXV] In an electromagnetic brake wherein the axis of the electromagnet coincides with the axis of a shaft upon which is rigidly mounted a brake rotor member carrying a braking surface, a co-operating braking surface being provided by a second member, disposed between the brake rotor member and the electromagnet, which at the same time serves as an armature for the electromagnet, means is provided for axially adjusting the shaft with respect to the electromagnet and the second member. In the embodiment illustrated, the electromagnetic brake arrangement 3 is contained within a casing 1 which houses an electric motor unit 2. Secured to the rotor of the electric motor unit 2 is a shaft 4 which rotates in bearings 5 and 6. Also secured to the shaft 4 is a brake rotor member 7 which carries an annular friction lining 8 adapted for frictional engagement with a non- rotatable disc 10 which is axially slidable on pins 15 and acts as an armature for the brake arrangement 3. The disc 10 is arranged to bias towards the brake rotor member 7 by spring 9 ; a gap being formed between the electromagnetic unit 11 and the disc 10, the latter being attracted only when current is supplied to coil 14 through cable 18, i.e. when the motor is energised. The electromagnetic unit 11 is rigidly connected to an end shield 16 by studs 17 and a nut 19 engages a threaded portion of the electromagnetic unit 11 and abuts the outer ring of the bearing 6, which is axially slidable in end shield 16; the inner ring of which, in turn, bears against a shoulder 21 on shaft 4. An externally screw-threaded plug member 22 is provided to engage a screw-thread in an opening in the end shield 16 and to abut the outer ring of bearing 6. Adjustment of the air gap is achieved by turning the nut 19 in the desired direction, e.g. with clockwise rotation, while the casing 1 and shield 16 are disassembled, the bearing 6 bears against the shaft shoulder 21 and the shaft 4 carries with it the brake rotor member 7 to move the disc 10 in the same direction to decrease the air gap. When the desired gap has been obtained, the plug member 22 is screwed into the end shield 16 so that it abuts bearing 6 and securing pin 19a, provided on the end shield 16, prevents rotation of nut 19.
