Abstract: 1,247,445. Heptenes. B.P. CHEMICALS Ltd. 21 April, 1970 [29 May, 1969], No. 27309/69. Heading C5E. Heptenes are produced by (a) co-dimerizing ethylene and propylene to form pentenes, (b) isomerizing at least part of the product to increase its content of pentene-2, and (c) codimerizing with ethylene the pentene mixture containing pentene-2; the catalyst in steps (a) and (c) being one prepared by dispersing Na and/or Li on an anhydrous potassium compound, e.g. a silicate, halide, sulphate, or particularly the carbonate. Suitable step (b) catalysts include silica/alumina, natural clays, supported phosphoric acid, heteropoly acids, sulphided nickel-on-sepiolite, and potassium on alumina. Steps (a) and (c) may be conducted separately or by recycling the feed for step (c) over the step (a) catalyst, and the catalyst for these steps may be hydrided and activated, suitable methods being given. Hydrogen may be present during steps (a) and (c), or the catalyst may be intermittently contacted with hydrogen while the feed is discontinued.

Abstract: 355,543. Vibration-dampers. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Sept. 17, 1930, No. 27756. Convention date, Feb. 20. [Class 108 (iii).] In order to damp the vibrations of an overhead electrical transmission line or the like, containers partially filled with a movable substance such as a liquid are freely suspended from the line, the movements of the substance within the container being utilized for the damping. In the arrangement shown in Fig. 2, a container 7 suspended from a line 1 and charged with a viscous fluid is divided into chambers 9, 10, 11 by two partitions 8, each formed with a central aperture 12. To increase the resistance to motion of fluid flowing from one chamber to another due to vibration of the container, movable plates 14 are arranged above the apertures 12. The chambers 9, 11 may be connected bv external conduits 13. In the construction shown in Fig. 3, a fluid-charged container 15 is suspended from a line 1, flaps 16 being arranged inside the container to increase the resistance to vibration of fluid within the container. In a modified arrangement shown in Fig. 1, fluid-charged containers 2, 3 connected by fluid and air pipes 5, 6 respectively are carried by a line 1 to damp the vibrations thereof. The pipes 5, 6, which may be flexible, may be formed with restricted bores.

Abstract: 510,396. Starting prime movers. GENERAL MOTORS CORPORATION. Sept. 23, 1938, No. 27769. Convention date, Sept. 23, 1937. [Class 38 (iv)] [Also in Group XXVII] In an internal-combustion engine having a starting motor and a carburetter provided with air and mixture throttle valves, a device operated by the mixture throttle valve modifies the action of the air valve and also controls the operation of the control switch for the starting motor. Engine suction may operate to open the control switch after the throttle movement has closed it and the air valve may be subject to both a heat sensitive control and to engine suction. The starting motor 260 of an internalcombustion engine can only be excited when the engine is at rest and the throttle 16 opened about 30 degrees under which conditions closure of the ignition switch 322 connects the battery 292 through a control 170 (shown in the disengaged position) and lead 314 to a solenoid 310 which rocks a lever 272 to engage the starter unit with the engine shaft andcloses a switch 286, 284, 288 to excite the motor 260. The control 170 unit comprises fixed and movable contacts 182, 180, the latter carried by a spring arm 184. A rod 208 operatively connected to a cam 130 on the throttle shaft 20 holds the contacts apart until the throttle has been opened to about 30 degrees. The casing of the control unit is airtight and connected by a passage 88 to the induction pipe to permit engine suction to displace a diaphragm, &c. 226 and rotate a cam member 212, a latch 252 on which engages a stud 250 on the spring arm 184 and prevents closure of the contacts 180, 182 when the engine is running under its own power. The diaphragm 226 responds to slight pressure changes but is prevented from engaging the latch 252, 250 during cranking by a spring pressed detent 254 engaging a recess in the sleeve 258 carrying the cam 212.

Title: A method of improving the performance of an open hearth furnace
IPC: C21C5/04
Filed: 1960-08-11
Abstract: The performance of an open hearth furnace, such as one heated by producer or natural gas or by means of an oil and air burner, is improved during the melting period (see Fig. 1) by blowing oxygen through water-cooled lances 4 vertically into the flame 3 entering from the furnace end, and during the refining period, Fig. 2 (not shown), by adjusting and arranging the distances of the lances from the surface of the molten iron, e.g. by a lifting mechanism 6, to effect a wide superficial contact of oxygen and avoid or reduce to a minimum any Fe2O3 smoke.  During both periods, the oxygen is blown at a pressure between 0.2 and 0.8 atmosphere in excess of atmospheric pressure, and leaves the lances at a velocity of between 50 and 250 metres per second. <FORM:0949834/C3/1>
