Title: Improvements in process of treating oils and other similar hydrocarbons to promote cracking
IPC: C10G11/04
Filed: 1927-01-31
Abstract: 289,556. Dehn, F. B., (Schuster, M. B.). Jan. 31, 1927. Hydrocarbons, cracking. - The cracking of hydrocarbon oils such as black asphalt, crude oil, kerosine, gas oil, lubricating oil, tar residuum, &c. is promoted by adding before or during the heat treatment a colloidal substance such as bentonite, hydrated lime, &c. The forms of bentonite which form jellies on admixture with water or alcohol are suitable. The colloidal substance may before addition to the oil be dispensed in or formed into a gel with water, alcohol or a portion of the oil. The addition of the colloidal substances to the oil renders it less viscous, and results in a distillation residue resembling natural asphalt in its content of mineral matter. Bentonite or other natural colloidal substance may be treated with hydrochloric, sulphuric &c. acid prior to use.

Title: Improvements relating to the control of hydraulic wire extrusion presses
IPC: B21C31/00
Filed: 1962-01-29
Abstract: 995,856. Extruding; winding and reeling. HYDRAULIK G.m.b.H. Jan. 29, 1962 [Jan. 28, 19611, No.3341/62. Headings B3E and B3P. [Also in Division G3] An hydraulic wire extrusion press has a winding reel 7 for the extruded wire 5, whose speed is controlled by the differential of a first measured value corresponding to the speed of the wire and a second measured value corresponding to the speed of the reel. The wire is produced by the extrusion of a billet 2 through a die 4 by means of an hydraulic ram 1; the extruded wire passes through a guide tube 6 to a Garret reel 7. Ram 1 supports a rack 8 driving a pinion 10 connected through an electromagnetic clutch 13 and shaft 11 to a D.C. generator 12. The clutch 13 is operated automatically in response to the pressure in the press cylinder so as to be disconnected below an adjustable minimum pressure. Generator 12 is connected through magnetic amplifier 14 and potentiometer 15 to one leg of a bridge amplifier 16, and also through potentiometer 38 and amplifier 37 to a D.C. variable speed motor 36. Potentiometer 15 is adjusted manually in accordance with the extrusion ratio and potentiometer 38 is adjusted manually to suit the diameter of the wire being extruded. Motor 36 drives a saw-tooth generator 35, consisting of two parallel-connected ring potentiometers driven out of phase, Fig. 4 (not shown), whose output is connected to a separate winding of the magnetic amplifier 14 so as to superimpose a cyclically varying voltage upon the voltage produced by generator 12. This is stated to produce even winding on the reel. The latter is driven by a polyphase induction motor 18 through an infinitely variable hydrostatic transmission unit 19 or alternatively through a torque converter. The primary unit 22 of the transmission has its output adjusted automatically by a servo piston 24 controlled by a slide valve 27 fed with pressure liquid by a gear pump 28 driven by motor 18. A stabilized power supply 30, 31 feeds a potentiometer 32 whose slider is coupled to the servo piston 24 so that the output voltage is proportional to the reel speed. This output is fed through a manual speed regulator 34 to the other leg of bridge amplifier 16. The differential output therefrom controls the slide valve 27. A relay 40 is connected through an amplifier 39 to the main press control whereby the connection to the bridge amplifier is opened when the press stops. A further time-relay 41 causes the reel to continue rotating for winding the end of the wire after severing of the discard. In another embodiment, Fig. 5 (not shown), the reel drives a second generator, which produces a voltage corresponding to the speed of the reel.
