Title: Purification of alcohols by distillation
IPC: C07C29/80
Filed: 1950-03-30
Abstract: Crude alcohols such as those obtained by Oxo synthesis, are purified from thermallyunstable, higher-boiling, non-alcoholic impurities by distillation under sufficiently reduced pressure and under controlled conditions of temperature and time such that the higher-boiling impurities do not decompose to give volatile products which would contaminate the alcohol distillate.  The crude alcohol is preferably subjected to a preliminary topping distillation to remove low-boiling impurities.  The purified alcohols are suitable for esterification in the manufacture of plasticizers.  In the example, iso-octyl alcohol prepared by reaction of a C7 olefin feed with carbon monoxide and hydrogen in the presence of a cobalt catalyst followed by catalytic hydrogenation, was topped and then distilled in a 12-plate column under a pressure of 250 mm., so that the bottoms temperature never exceeded 226 DEG  C.  The alcohol removed overhead gave a phthalate ester with a Hazen colour only 40 per cent of that given by the ester obtained from the alcohol obtained by fractionating the crude alcohol at atmospheric pressure.ALSO:Crude alcohols such as those obtained by OXO synthesis, are purified from thermally-unstable, higher-boiling, non-alcoholic impurities by distillation under sufficiently reduced pressure and under controlled conditions of temperature and time such that the higher-boiling impurities do not decompose to give volatile products which would contaminate the alcohol distillate.

Title: Improvements in the production of copper alloys
IPC: C22C9/00
Filed: 1943-05-21
Abstract: A process for removing brittleness from bismuth-bearing copper or bismuth-bearing copper alloys consists in melting the metal, deoxidising the same as necessary in order to free it substantially from oxygen, and adding lithium in amounts up to 0.1 per cent., the final product containing both bismuth and lithium, the former preferably in amounts up to 0.01 per cent.  The process may be applied to copper and copper alloys as follows. Non-arsenical copper alloy containing 0.003-0.007 per cent. bismuth is melted, deoxidised with sufficient phosphorus to leave a residium of 0.01-0.05 per cent. of phosphorus and 0.035-0.1 per cent. lithium is added.  0.01-0.1 per cent. lithium is added to a molten deoxidised arsenical copper alloy containing 0.001-0.01 per cent. bismuth and 0.3-0.5 per cent. arsenic.  This deoxidised copper alloy may be obtained by treating with sufficient phosphorus to leave a residium of 0.01-0.05 per cent. phosphorus. Copper-cadmium alloys containing 0.5-1 per cent. cadmium and 0.001 to 0.01 per cent. bismuth are melted, deoxidised and treated with 0.01-0.05 per cent. lithium.  A copper-cadmium alloy containing 1.0 per cent. cadmium and 0.006 per cent. bismuth is melted, treated with phosphorus to leave not more than 0.014 per cent. phosphorus and treated with 0.01-0.05 per cent. of lithium. Copper-tin alloys containing up to 12 per cent. tin and 0.001-0.01 per cent. bismuth are melted, deoxidised and treated with up to 0.01 per cent. lithium.

Title: Improvements in Slice Collectors for Meat, Bread and like Slicing Machines.
IPC: B26D7/32
Filed: 1918-05-17
Abstract: 118,824. Berkel & Parnall's Slicing Machine Manufacturing Co., (Berkel, C. F. M. van). May 17, 1918. Cutting slices in succession. - A disk-knife meat-slicing machine is provided with a number of elongated tines or spikes to receive the cut slices, and with an impaling and a pressing device to force the slices backwardly on the tines. The base 10 carries the reciprocating table 14 and rotary disk knife 11, constructed and actuated in a known manner. On a bracket 25 is pivoted an oscillating slice-receiving table 27, moved to the left synchronously with the table 14 by a flexible band 30 attached to the table 14 at 32 and to the table 27 at 31. The band engages a downwardly projecting rim 29 on the table 27. The table 27 is returned by a spring 33 on its upright standard 26. This standard provides a bearing for a curved vertical receiving-plate 36 which has a number of projecting tines 41 to receive thereupon the cut slices. The tines pass freely through a vertical curved plate 40 which is carried by, and can be forced outwardly to remove the collected slices from the tines by pins 39 slida.ble in guides 38 on the plate 36. As the meat table 14 moves towards the left, whereby a slice is cut off, the table 27 also moves to receive the slice upon the tines, and then passes in front of a guard-plate 42, Fig. 4, acting also as an impaling-plate and having a series of triangularly-shaped notches or grooves 44, which receive the points of the tines and force the meat on to the tines. On moving farther to the left, the plate 27 with the tines and meat thereon pass in front of a curved plate 47, which is a detached extension of the plate 42 and has grooves registering with the notches 44. This plate is carried by a standard on a slide-bar 55, normally forced away from the axis 26 by a. spring 59, but caused to approach it when the table 27 is at its extreme left position, by means of a roller 62 on the slide-bar engaging one end of a lever 63, the opposite end of which is engaged by a roller 65 on a curved extension 66 of the usual actuating-pitman 20 of the meat table 14. By this means, all the slices of meat on the tines are forcibly pressed backwards, and the tines project sufficiently to receive the next slice. The slices are eventually removed as above stated. In a modification, the collector table is shaped so as to be entirely on that side of the pivotal support which is away from the slicing-knife, so as to enable all the tines to enter the meat at right-angles. In a further modification, the ends of the tines are curved outwards to a varying amount, the greater curvature being given to those on the extreme right side, or farthest from the axis, while those on a line with the axis are quite straight.
