Title: Improvements in or relating to a process for producing dialkyl aluminium hydrides
IPC: C07F5/06
Filed: 1959-01-29
Abstract: Dialkyl aluminium hydrides are prepared by reacting inactive aluminium, hydrogen, an aluminium alkyl or alkyl aluminium hydride and an activator consisting of an alkali or alkaline earth metal or an alkaline compound thereof together with an a -olefin.  The a -olefin may have from 2 to 20 carbon atoms in the molecule, and both it and the hydrogen used should be free from oxygen and moisture.  It is preferred that the aluminium should be finely divided.  It may be slurried in a liquid medium such as hexane, heptane or other aliphatic hydrocarbon or benzene, toluene or other aromatic hydrocarbon, or in the dialkyl aluminium hydride itself.  When using media other than dialkylaluminium hydride, it is advantageous to have 3%-10% of dialkyl aluminium hydride initially present.  Reaction may be carried out between 60 DEG C. and 250 DEG C. and between 100-15,000 lbs. per sq. inch pressure.  The activator may be lithium, sodium, potassium, rubidium, cesium, calcium or barium or their aluminates, carbonates, bicarbonates, hydroxides, acetates or other carboxylates.  The process may be carried out batchwise or in a continuous manner.

Abstract: 1303444 Controlling jib cranes BALDWINLIMA-HAMILTON CORP 23 Jan 1970 [27 Jan 1969] 3396/70 Heading B8B A control device 35 for a jib crane 10 mounted on a vehicle 12 prevents the free end of the boom from passing a predetermined surface fixed with respect to a selected point remote from the vehicle. A vehicle orientation linkage assembly 36 has its first link 44 brought to a vertical position by an electric motor 68 operated in response to a mercury switch 72 mounted on the link 44. This positions a set of stops on a bank 38 mounted on a link 60 supported by links 46, 47 from the link 44. A jib elevation and length follower 42 causes corresponding movement of a switch bar assembly 40 with an arm 106 fixed to extend towards the path of the bank 38 of stop pins. The lowermost stop pin 83 acts as a reference point, one of the other pins 82<SP>1</SP> being selected to correspond to the selected surfacein this case a horizontal plane. The relative position of the bank 38 to the link 44 is normally fixed by a spring loaded friction brake acting between surfaces 134, 136 but this may be released by activating a solenoid 132 (the device 35 being inoperative). If this is carried out when the head 28 of the jib 16 is positioned at the selected reference point the reference stop pin 83 is brought to its required position, whereupon the solenoid 132 is deactivated and the control device 35 is set ready for use. The control device 35 may be modified to maintain the jib end 28 in a preselected vextical plane (not shown), or may be modified to maintain the jib end 28 in a predetermined curved or complex path by shaping the underside of bar 104, associated with the arm 106, appropriately, (not shown).

Abstract: 979,989. Feeding record tapes. POTTER INSTRUMENT CO. Inc. Jan. 28, 1963 [Jan. 31, 1962, No. 3446/63. Heading G5H. Multiple-loop tensioning arms 12 and 13 Fig. 1 for a magnetic tape are normally tensioned by springs 15 and 17 respectively and as shown in Fig. 4, each of these springs, shown as 15<SP>1</SP> in Fig. 4, acts on a link 19 keyed to the shaft 14 carrying a tension arm (not shown in Fig. 4). A lug 21 on link 19 is engageable by a projection 22 on a link 23 which is free to rotate on shaft 14 except as determined by a flexible cable 24 and return spring 25 which are bolted to the link. To release tension a switch (not shown) is operated to cause an electric motor 30 to rotate until stopped by a limit switch ; the rotation of the motor winds up cables 24a and 24b on a cylinder 33 so causing respective links 23 to rotate; the projections 22 on links 23 engage lugs 21 and cause links 19 to rotate, thus turning shafts 14 and swinging the arms 12 and 13 to position when they do not tension the magnetic tape. Operating a second switch (not shown) causes motor 30 to rotate in the opposite direction until stopped by a limit switch; the projections 22 then disengage from lugs 21, and the arms 12 and 13 are tensioned by their respective springs. Dashpots 27a and 27b prevent the tension arms being damaged if the tape breaks.
