Patent GB-1234679-A (GB)
IPC: C21D1/09
Filed: 1969-03-26
Abstract: 1,234,679. Welding by fusion; removing metal by fusion. ELEKTRO-THERMIT G.m.b.H. 26 March, 1969 [27 March, 1968], No. 14220/69. Headings B3R and B3V. To remove, or minimize the formation of, riffles (periodically recurrent undulations due to wear) on a bearing and/or guide surface of a railway or tram track rail, all or part of said surface is melted, e.g. by non-consumable or consumable electrode arc welding, and then allowed to cool and solidify. When using a non- consumable (e.g. argon-shielded tungsten) electrode, the surface composition remains the same. When using a consumable (e.g. gasshielded or submerged-arc wire) electrode the surface composition may be altered so as to minimize the formation of further riffles. Any projecting surplus material supplied by the electrode may be removed, e.g. by grinding. A consumable electrode is suitably of low-melting or unalloyed material, e.g. by weight 0À12% C, 0À2% Si, 0À5% Mn, balance Fe and impurities. The rail may be processed disassembled or laid as track. Melting equipment may be moved along the track manually or by motor. A narrow melting zone and a single bead is usually adequate. The zone may be straight or zigzagged or sinusoidal.

Abstract: 1289272 Television for photograph analysis COMISSARIAT A L'ENERGIE ATOMIQUE 29 April 1970 [29 April 1969] 20610/70 Heading H4F . A series of sequential photoaraphs of an event, e.g. a cine-film of a bubble chamber interior are analysed as to content, and events shown therein are dimensionally measured by a closed circuit television system. The system comprises, Fig. 1 mounted under a film carrying, advancing, illuminating and holding system 1, 2, 3, 4, 5- two television cameras 6, 7 mounted on a trolley 26 for movement from one photograph to the next. Camera 6 views the photograph via a semi-transparent mirror 8 or 9 and uses its cooperating picture tube 23, Figs. 5 to 8, to project all of the photograph on to a screen 24 of a viewing consol, Fig. 3, with a X30 magnification. Camera 7 is able to move in recorded X and Y dimensions to view in detail any portion of the photograph. A variable camera lens allows the viewed portion to be seen on picture tube 25 (screen 14) with a magnification of x 30 to x 100. An arrow image is projected on to the screen 24 to indicate the selected portion. A third camera 12 is used to show a picture of the photograph on screen 15 together with marks for measuring the lengths of any desired trace. In the measuring sequence of Figs. 5 to 8, picture 18 is first illuminated and viewed by cameras 6 and 7. Picture 19 is then illuminated and viewed by both cameras. Mirror 9 is then moved away and both pictures illuminated. Both pictures are then viewed and the outputs of both cameras are fed, using same magnifications, to projection picture tube 23. The two pictures are superimposed on screen 24 to show any changes. Picture 18 is then only illuminated and camera 12 enables any desired measurements to be taken. Fig. 2 (not shown) shows how three films may be analysed side by side, using three sets of cameras 6, 7 but using only one measurement camera 12 which is laterally movable from one film to the next.

Abstract: 1290710 Calendar clocks JAZ S A 22 Dec 1969 [13 Jan 1969] 62433/69 Heading G3T A calendar device for a clock comprises a band marked with date indications and driven by the clock movement. The band itself drives a drum on which the months are marked. In the arrangement shown, a band 10 rotates a roller 12 by means of spigots 15a, (15b) engaging in perforations 14. When the month is to be changed, a further perforation 11 engages one of two spigots 9 which lie against the roller 12. The spigot 9 passes through the perforation 11 into a bore (16), Fig.2 (not shown) in the roller, and a wheel 3 carrying the spigots 9 is rotated by an amount sufficient to change the month indicated by a drum 1, which is keyed to the wheel 3 by a spigot 7 engaging in one of a series of holes 6. The drum is secured to a milled head 4, both the drum and the head being free to rotate on a shaft 2. By turning the head 4, the desired month can be manually set, the wheel 3 being prevented from rotating by the roller 12, and the spigot 7, which is mounted on a resilient blade 8, withdrawing from one of the holes 6 and subsequently engaging in a following hole.

Abstract: 1311614 Producing Al 2 O 3  from clay ARTHUR D LITTLE Inc 18 March 1971 7240/71 Heading C1A α-Al 2 O 3  is produced by calcining clay, leaching with aqueous HNO 3 , flocculating and removing solids, contacting the leach liquor with an extractant dissolved in a water-immiscible organic solvent to extract Fe, feeding the aqueous Al(NO 3 ) 3  solution into a fluidized bed to form Al 2 O 3  and HNO 3  vapour, and heating the Al 2 O 3  to remove residual NO 3  and form α-Al 2 O 3 . Calcination may be effected at 700- 850‹ C. in a fluidized bed, rotary kiln, or shaft kiln. Leaching may be effected at 100-145‹ C. using 35-55 wt. per cent HNO 3 , at or above atmospheric pressure. The extractant may be di - (2 - ethylhexyl) - hydrogenphosphate with tributul phosphate or a high M. wt. primary amine dissolved in kerosene. The extraction may be effected at 50-60‹ C. in countercurrent using an aqueous/organic volume ratio of 2/1 to 10/1. The fluidized bed may be operated at 150-350‹ C., with gases in the bed containing 25-45 vol. per cent H 2 O vapour to hydrolyse the A1(NO 3 ) 3 . Additional H 2 O may be injected into or below the bed, or may be produced by combustion of the fuel used to heat the bed. Solids may be withdrawn in the gases and/or from an overflow. The final heating may be carried out in a pebble heater in one step at 1000‹ C., or in a first step at 400‹ C. followed by a 2nd step at 1000‹ C. in a rotary kiln. The N oxides evolved may be converted into HNO 3  and recycled together with HNO 3  from the fluidized bed heating. The loaded extractant may be washed with water, stripped with aqueous HC1, washed with water, and recycled.

Abstract: 1318347 Film fibrillation JAMES MACKIE & SONS Ltd 11 Sept 1970 [22 Sept 1969] 46594/69 Heading B5B A process for fibrillating a tape of a synthetic thermoplastic polymer, e.g. polypropylene, which has been longitudinally orientated comprises feeding the tape into contact with a surface, preferable a roller, which is driven in the same direction as and at a speed greater than, that of the tape and is covered with irregularly shaped particles of a hard, wear-resisting material which are at least of a size corresponding to grade 40 grit (B.S. 872). The fibrillating surface may comprise particles of grit, e.g. alumina, bonded by a layer of resin to a flexible backing. Apparatus suitable for the process of the invention comprises guide roller 2, guide plate 3, backing rollers 4 and 4<SP>1</SP> and guide plates 6 and 7 over or through which the stretched tape 1 passes prior to contact with the flexible covering of particulate material 12 on a fibrillating roller 5. After fibrillation the tape passes over guide rail 25, front rolls 11 and 11<SP>1</SP> to a normal spindle and ring twisting arrangement 14 being guided by a lappet 15. Fig. 3 (not shown) illustrates a similar arrangement in which the covered fibrillating roller 5 is replaced by a moving endless belt 20 supported by an arcuate plate 23 over the area of contact with the tape 1. In both embodiments the front rollers 11, 11<SP>1</SP> are driven at a slighter faster speed than the back roller 4, 4<SP>1</SP> to maintain tension in the tape and the fibrillating surface moves at a speed in excess of the speed of travel of the tape. In an example polypropylene tape is fibrillated by a roller covered with grade 24 grit moving with a surface speed 3À5 times that of the tape.

Title: Shaped body of zeolite, a process for its production and its use
IPC: B01J20/18

Abstract: A shaped zeolite-containing body, e.g., zeolite-containing monoliths, having high compressive strength is prepared from a particular class of siloxane-based binders in combination with zeolite, plasticizing agent, and methylcellulose. It has been discovered that when using the particular class of siloxane binder with the aforementioned components, the body formed therefrom can be processed and calcined at temperatures below 300° C., thereby reducing costs typically seen with other processes for preparing shaped materials containing zeolite. The shaped bodies of this invention have been shown to have compressive strengths of at least 20 N/mm2 or more.
