Title: Improvements in or relating to the Thermal Cracking of Hydrocarbons
Inventor: DORNER ARMIN
IPC: C10G9/20
Filed: 1967-10-11
Abstract: 1,165,469. Thermal cracking. LINDE A.G. 11 Oct., 1967 [12 Oct., 1966], No. 46352/67. Heading C5E. In a process for thermally cracking hydrocarbons, e.g. benzine, to produce olefins in a cracking furnace comprising a convection zone and a radiation zone, wherein a hydrocarbonwater vapour mixture is initially heated in the convection zone through which pass hot flue gases leaving the radiation zone, and is then cracked in the radiation zone which is heated by hot combustion gases, the transition temperature of the feed between the convection zone and the radiation zone is regulated by controlling the heating in the convection zone. Said control may be effected by one of the following means:- (a) part of the hot flue gases leaving the radiation zone may be diverted so as not to flow through the convection zone; (b) part of the feed mixture may be allowed to by-pass at least part of the convection zone, being reunited with the remainder before the radiation zone; (c) the hot flue gases flowing through the convection zone may be cooled, e.g. by indirect heat exchange with water flowing through tubes within the convection zone.

Abstract: 962,127. Percussive drills. ENGLISH DRILLING EQUIPMENT CO. Ltd., and F. WALMSLEY. March 18, 1963 [Dec. 29, 1961], No. 46754/61. Heading B4C. [Also in Division E1] A pneumatic earth boring drill comprises a cylinder a adapted for connection to a drill string (not shown), a hammer-piston k in the cylinder, inlet and outlet ports r, s in the cylinder wall, and passages m, o in the piston for flow of air from and to the ports, the opening and closing of the ports being controlled by the piston. The drill string which is rotated is fixed to a connector c attached to a cushion assembly d which in turn is fixed to the cylinder, the connections being capable of resisting torque. Air from the drill string passes through passages c<SP>2</SP>, b<SP>2</SP> to an annular chamber e connected to the inlet ports r. The outlet ports s lead to an annular chamber e<SP>1</SP> connected to a passage f<SP>1</SP> through which air is discharged to remove cuttings and cool the bit g which is rotationally fixed to cylinder but has limited axial movement relative to the cylinder. In the lower position of the piston shown, air from the ports r passes through the passage m to the cylinder chamber n to raise the piston and air from the cylinder chamber p passes through the passage o to the ports s for exhaust. In the upper position of the piston, air from the ports r flows through the passage m to the chamber p and air from the chamber n is exhausted through the ports s. In a modification (Figs. 3, 4, not shown), the positions of the inlet and outlet ports are reversed. In the construction shown in Fig. 5 the piston 19 strikes a member 17 rotationally fixed to the cylinder 2 but having a limited axial movement relative thereto, and the member 17 is connected to the drill string which carries the bit. The cylinder is rotated by a shaft 3 and air is supplied to and exhausted from the cylinder by a non-rotary sleeve 28 having supply and exhaust connections 34, 35.

Abstract: 1390268 Recovery of copper from etching solutions SHIPLEY CO Inc 11 Oct 1972 [12 Oct 1971] 46794/72 Heading C7B Copper metal is recovered from an aqueous etching solution containing cupric ions by electrolyzing the solution while cooling the cathode and avoiding solution agitation to decrease the etching potential of the solution. In the apparatus shown the solution is contained in a double-walled tomb 1, e.g. of polyethylene, and is electrolysed between anodes 7 of graphite and stainless steel cathode 2. Cooling water is passed through the cathode from pipe 3 and may optionally be then passed through the jacket 5 of the container. The maximum temperature of the etchant solution is preferably 140‹F. while the temperature at cathode-solution interface does not exceed 90‹F. A loose, granular layer of copper forms on the cathode and is readily scraped off to be removed through outlet 16. After a part, preferably not over 80% of the copper has been removed from the solution, the compo-  sition of the solution is adjusted e.g. by addition of ammonium chloride and monoethanolamine and returned to the etching process for re-use.

Heading ASR [Also in Divisions G2 and H4] An optical probe for examining the interior surfaces of enclosures by reflecting a viewing beam from the interior surfaces, incorporates optical viewing beam transmission means and optical reflected beam receptive means simultaneously movable for examining different parts of an interior surface, and its own drive means for moving both said optical means. As described, an apparatus used to examine cavities within human and other bodies comprises a probe connected to electric power sources and to an oscilloscope, the probe including a mirror 38 which can be rotated about the probe axis and oscillated about a second transverse axis, and a lightsensitive device Z which receives light reflected from the mirror and then transmits signals to the oscilloscope, the movement of the mirror enabling the cavity to be scanned. The mirror rotates with a spindle 31 which moves within a bearing block 22 and is secured to a magnetized rotor 35 which is caused to rotate within a coil 29 and a magnetized outer member 25. A commutator disc 36 is secured to the rotor 35 and contacts a spring pin 52. A d.c. source activates the rotor in dependence on a transistorized switching circuit (Figure 4, not shown) connected to the pin 52. The mirror 38 of hardened steel has an extension 39 and is permanently magnetised so that it is caused to oscillate about an axis transverse to that of the spindle 31 by an A.C. source in a coil 37. The frequency of rotation is higher than that of the oscillation. The apparatus includes a lamp 55 providing the viewing beam. It is stated that as an alternative the probe may be powered by a clockwork mechanism.
