Title: Improvements in and relating to the treatment of liquid mixtures containing aldehydes
Inventor: TAYLOR ARTHUR WILLIAM CHARLES
IPC: C07C45/50
Filed: 1947-09-12
Abstract: Aldehydes are distilled from mixtures which contain residual catalyst comprising cobalt or a cobalt compound by a "flash distillation" in which the aldehyde is recovered in an overhead fraction.  The term "flash distillation" is defined and includes (1) supplying heat at a high rate to a liquid film; (2) submitting a warm liquid to less than atmospheric pressure; (3) letting down a hot liquid under pressure to a lower pressure.  The mixture may be one resulting from the reaction of olefines with carbon monoxide and hydrogen and may contain an inert diluent such as a high-boiling hydrocarbon.  In examples: (1) a crude non-aldehyde obtained by reacting di-isobutylene with carbon monoxide and hydrogen using metallic cobalt as catalyst was preheated to 92 DEG  C., and fed at 1 1/2 litres per hour to a point about one-third down a mild steel column packed with stainless steel rings and electrically heated so that the top was at 125 DEG  to 130 DEG C., and the bottom at 150 DEG  to 160 DEG  C.  Distillation was effected at about 150 mms. pressure.  Non-aldehyde was taken off overhead. (2) A crude product containing butyraldehyde, obtained by reacting propylene with carbon monoxide and hydrogen using metallic cobalt in an inert high-boiling hydrocarbon, was fed at 2 to 3 litres per hour and distilled in the same way, the preheat being to 80 DEG C., and the top and bottom temperatures being 100 DEG  and 150 DEG  C.

Abstract: 779,750. Testing fabrics. PRESS, J. J. Sept. 5, 1955 [Sept. 20, 1954], No. 25402/55. Class 42 (2). [Also in Group XIX] Apparatus for testing fabric by abrasion comprises a fabric mount 11, Fig. 4, with a flat surface on which the fabric 82 is mounted without strain, a friction mount 12 with a flat friction surface 60 parallelto the fabric mount surface, and means for producing relative orbital movement between the two surfaces in their plane of engagement, one mount being movable relatively to the other in a direction perpendicular to the said surfaces. As shown, the fabric sample 82 to be tested is secured without tension over a flat resilient pad 79 on the face of fabric mount 11 by means of a rubber band 81. Mount 11 comprises a block 75 detachably mounted on the end of a shaft 58 slidable in an arm 56 of the machine frame. A rod 64 fixed to arm 56 slides in a hole 67 in the head 63 of shaft 58 to restrain mount 11 against rotation. In its operative position, mount 11 is pressed by weights 68 downwardly against the friction surface 60 on friction mount 12. Surface 60 is provided by a piece of woven fabric held against a rubber pad 97 or a grooved aluminium disc, or directly against backing plate 19, by a screwed collar 99. The fabric 60 is preferably a plain, twill, herring- bone or basket weave and is preferably calendered; it may be formed of synthetic yarns or, where more abrasion is required, metal or metalcontaining fabric may be used. Friction mount 12 rests, on legs 20, on a disc 18, Fig. 5, and is keyed thereto by pins 22 engaging holes in the disc. Disc 18 is screwed to a strap 25 connected by eccentric pins 42, 43 to gears 27, 29 meshing with an idler 28. Gear 27 is driven by a shaft 37 so that strap 25, disc 18 and mount 12 describe an orbital path without rotation of mount 12 about its own axis. The fabric sample may be applied to block 75 without tension by means of a tool 90, Fig. 8, which holds it over the face of the block while ring 81 is rolled down into groove 80. In operation, the test sample,is subjected to the rubbing produced by the orbital motion of mount 12 for about one minute. The rubbed fabric is then inked, e.g. by placing a piece of carbon paper on surface 60 and operating the machine for a few cycles. The inking makes visible any pills produced by the rubbing, which are then counted; comparison may then be made with other similarly treated and marked areas and other pieces of fabric.

Addition to 674,172, [Group V], Class 106 (v) [Also in Group V] Consists in improvements in the method of forming and filling capsules of plastic material according to the parent Specification, whereby pre-measured, compacted and shaped charges of a filling powder are fed to the cavities in the strip of plastic material. In addition to the cavity die roll 12 and sealing roll 13, a roll 11 having a number of measuring cavities 15 in its periphery is used. The cavities communicate, through porous plugs '16 of felt, sintered metal or glass or fine metallic screening material, with manifolds 22, which, during the time that the cavities are beneath the filling hopper 49, are connected to vacuum conduits 27 in stationary valve plates 23. Powder is drawn into the cavities and the charge levelled off as the cavities pass under the front edge of the hopper. The charge is retained in the measuring cavities until they register with the die cavities in the die roll 12. At this point the manifold 22 passes from its connection to the vacuum conduits 27 and registers with pressure conduits (not shown) in the same valve plates 23. The charge is blown into the die cavities and the capsules then sealed by means of the sealing roll 13 in the manner described in the parent specification. After discharge, the measuring cavities pass on and are again connected to pressure which blows out any remaining powder into a dust receiver 52. Air jets. and brushes may also be used to clean the cavities.
