Title: Process for the manufacture of phenyl-aluminium compounds
IPC: C07F5/06
Filed: 1963-06-27
Abstract: Sodium phenyl aluminium compounds are prepared by the reaction of a sodium tetraalkyl aluminium compound with benzene in the presence of sodium alkoxides or phenyl sodium, and are subsequently decomposed to yield triphenyl aluminium.  1 mol. of a sodium alkoxide containing 4-10 carbon atoms, added in portions, may be used per mol. of sodium tetraalkyl aluminium, and the reaction carried out at 60 DEG  to 250 DEG  C.  The precipitate of sodium tetra-phenyl aluminium first formed may be recrystallized from tetrahydrofuran, or may be converted to triphenylaluminium by treatment at e.g. 100 DEG  C. with an aluminium halide, e.g. AlBr3 in benzene, or with a liquid alkyl aluminium halide, Sodium halide formed is removed, and by-product alkyl phenylaluminium compounds decompose on heating, e.g. during subsequent vacuum distillation to triphenyl aluminium and trialkyl aluminium. The residue after distillation at, finally, 10-3 Torr and 140 DEG  C. is triphenylaluminium.  When insufficient sodium alkoxide is used, incomplete conversion to e.g. sodium diphenyl dialkyl aluminium is achieved.  Intermediates wherein one or more alkyl groups of sodium tetra-alkyl aluminium are replaced by alkoxy groups are said to be formed, and such compounds may also be used as the starting material.

Abstract: 626,871. Testing physical qualities of materials; dynamometers. ARTHUIS, A. R. Aug. 27, 1946, No. 25587. [Class 106 (ii)] In a hydraulic machine for testing materials by tension, compression, bending, shearing, &c., the actual press is combined with a dynamometer which gives simultaneously a reading of the load on a dial, and a diagram showing the load and strain of the specimen, the dynamometer being connected to the source of hydraulic pressure in the press, and the indication of the strain being obtained by causing the movement of the piston in the press to move a sheet of paper on which the diagram is traced. A ram 2, in a cylinder 3 supplied with liquid by a hand pump 8, is connected, for tensile tests, to the upper clamp 9 for a test-piece E, and the lower clamp 10 is connected to a verticallyadjustable screw 11. The ram 2 contains several inner concentrically-arranged rams which can be brought into use to vary the sensitivity of the machine. For hardness tests, a tool having a steel ball is attached to the end of the screw 11 and the test-piece rests on the top of the composite ram 2. The cylinder 3 is connected by a pipe 7 to a hydraulic dynamometer D where the liquid forces upwardly a plunger 5 (not shown) against the action of a spring. To alter the sensitivity of the dynamometer a slidable sleeve may be arranged to bring further springs to bear on the plunger. The plunger 5 is connected by a cable C to a pulley 29 mounted on an axle to which an indicator 29a is secured and movable over a dial 14 having several scales to suit the different ranges of the machine. A pin 20 (not shown), secured to the plunger 5 and projecting through a slot 201 in the casing thereof, is connected to a cable 21 which, after passing around a twostage pulley 22 to magnify the movements of the pin 20, is connected to a stylus 19 slidable vertically on a rail 23. The stylus 19 engages a record web mounted on two drums, one, 15, of which is positively driven by a cable 18 and pulley arrangement by the movement of the ram 2, the free end of the cable having a counterweight 24 attached thereto. The stylus 19 this traces a diagram showing the relationship between load and strain.

Abstract: 737,561. Knitting-machines. CHARNWOOD ENGINEERING CO., Ltd. Jan. 16, 1953 [Nov. 1, 1951], No. 25596/51. Class 74 (2). A circular knitting machine having quality control mechanism is provided with a yarn furnishing device, the rate of delivery of which is varied in accordance with the variation in stitch length. An elastic yarn is fed through conical rollers 17, 18, the position of the yarn being varied by guide levers 23, 24 which are connected by a lever system to a lever 5 which operates the stitch cam 4. In knitting surgical hose with a heel pouch of non-elastic yarn the elastic feeder 10 is put out of action when necessary by mechanism 15, 16, and a clutch 20 is disconnected so as to break the drive to roller 17. If the elastic yarn is to be laid in between knitted loops of non-elastic yarn, a yarn guide 30 is provided to permit the rate of feed of the elastic yarn to be reduced without moving the stitch cam. The guide 30 is connected to the main guide 23 by a stop 37 on the main guide and a spring 38, so as to normally follow the movements of guide 23, but is movable independently of lever 23 from a stud 32 on a control drum 7 through a link and lever system. In a second embodiment the furnishing device comprises one conical and one cylindrical roller, and the rate of feed is adjusted as the tension in the yarn varies due to alteration in the length of the loops drawn.
