Title: Synthetic process for producing ª--cyanpropion-alde
IPC: C07C27/22
Filed: 1960-06-02
Abstract: b -cyanpropionaldehyde is obtained by reacting acrylonitrile with carbon monoxide and hydrogen in the presence of cobalt carbonyl in a reaction medium comprising a Lewis' base, contacting with an oxidizing agent to decompose the cobalt carbonyl complex formed, separating the decomposed complex, and distilling the residual solution to remove the solvent.  Lewis bases are defined, and exemplified by alcohols and ketones.  The decomposed complex is separated either by adding a mineral acid and removing the resulting water soluble cobalt salt by an ion exchange resin, or by precipitation followed by filtration or centrifugation.  Any acetal in the residual solution is hydrolysed in the distillation, the aldehyde being obtained from the bottom and the solvent alcohol from the top of the distillation column. Specification 838,737 is referred to.

Patent GB-687212-A (GB)
Title: Improvements in or relating to the manufacture of artificial yarn
IPC: D02J1/22
Filed: 1950-07-28
Abstract: A device for stretching a bundle of acid-wet artificial cellulose filaments received from a spinneret comprises a pair of sets of spaced parallel rods, those of one set being interleaved with those of the other set, a fixed member carrying one of the sets and a pivoted member carrying the other set, with the rods of the two sets displaced to provide a zig-zag path of increasing sinuosity for the filaments passing thereover; the pivoted member is capable of movement about an axis parallel to the rods, whereby the overlap of the zig-zag path may be varied, and means are provided for urging the pivoted set of rods into a position of increased overlap with respect to the fixed set of rods. Preferably each set of rods is carried by a bar, the bars are pivoted together, and one bar is weighted to urge it towards the other bar.  The device may be used in the production of rayon threads from viscose with coagulating baths of concentrated sulphuric acid.  Stretching of 300-400 per cent may be effected. As shown, filaments extruded from spinneret 1 form a yarn 3 as they travel through an acid coagulating bath towards roller 4, which is mounted loosely on spindle 5 outside the bath liquid. The liquid may splash on to spindle 5 so as to <PICT:0687212/IV (a)/1> <PICT:0687212/IV (a)/2> act as a lubricant for roller 4.  The yarn passes to freely-mounted roller 6 and thence to a stretching device 8.  This device comprises two sets of parallel rods of glass, stainless steel, sintered alumina or other acid-resistant material, one set a, b, c, being secured to bar 9 and the other set, a1, b1, c1, being secured to bar 10.  Bar 9 is pivoted to bar 10 by pin 16, and its free end carries a rod 11 along which a weight 12 may be moved to vary the downward force on the upper set of rods, a, b, c. After threading the yarn through the device, the bar 9 is lowered to a position such that the yarn follows a sinuous path in which the extent of the zig-zag increases from the feeding end to the delivery end.  The position of the rods and the path of the yarn during the stretching operation are indicated in broken lines in Fig. 2.  The yarn tends to arrange itself in the form of a flat band or ribbon as it passes through the stretching device.  The yarn passes from the stretching device 8 to a roller 13.  Further stretching may take place between rollers 13 and 15, and between roller 15 and a delivery cylinder.  Rollers 6 and 15 have radial passages extending from their peripheries to the spindle 7 so that coagulating liquid passes to spindle 7 and acts as a lubricant therefor.  Roller 13 or its spindle is helically grooved to draw up bath solution between spindle and roller for lubrication.  Specifications 287,553, 318,258, [both in Class 2 (ii)], 396,901, 397,509, 650,896 and 652,645 are referred to.

Abstract: 696,338. Making commutator bars; forging. GENERAL MOTORS CORPORATION. Aug. 13, 1951 [Aug. 29, 1950], No. 18972/51. Classes 83 (ii) and 83 (iv). In a method of making commutator bars, two segments of bar stock of the required crosssection are located side-by-side in spaced parallel relation, and rigidly confined on all sides of their cross-sections except for the inward facing sides, and then subjected to endwise pressure to form dovetail tangs on their inner edges. A sectional die 26, Figs. 2 and 9, is carried in the tapered bore of a sleeve 23 mounted for limited axial movement over a bolt 24 in a die holder block 22 on a press platen 20. The sleeve 23 is urged from the platen by a spring 39 engaging between the sleeve and a sleeve 38. Within the sleeve 38 is mounted a two-part bushing 36 which guides a first punch 30, whose corss-section conforms to that of the die cavity 29 and which is riveted to half bushes 32, Fig. 2, beneath which an ejector-rod 34 engages. The press slide 21 carries a pusher bar 45 and a second punch 48, held within twopart sleeves, 43, 46 respectively. In operation, bar stock is fed through a guide 51, Fig. 7, sheared to length by a plate 54 and presented to the die 26. On the first stroke of the slide the pusher bar 45 forces the segments into the die, the punch 30 and ejector moving down to the lower limit of their movement so that the punch 30 partially forms the tangs, Fig. 2. The slide is then retracted, moved laterally to align the punch 48 with the die, and the second stroke of the slide completes the formation of the tangs, Fig. 3. This final deformation causes material of each segment to upset inwardly against the other, frictional engagement between the segments and the die causing the die and sleeve 23 to move downwardly against the spring 39 to complete the formation of the lower ends of the tangs by the punch 30. Ejection of the finished bars by operation of the rod 34 causes the sleeve 32, Fig. 2, to engage and lift the sleeves 36, 38 and return the sleeve 23 and die to their upper position, and on retraction of the ejector the spring returns the sleeves 36, 38 to their lower position.
