Title: Method of manufacturing bearing bushings
IPC: B22F3/11
Filed: 1933-04-28
Abstract: 423,582. Bearing materials. MANGANESE BRONZE & BRASS CO., Ltd., Caxton House, Tothill Street, London.- (Chrysler Corporation; 341, Massachusetts Avenue, Detroit, Michigan, U.S.A.) April 28, 1933, No. 12457. [Class 12 (i)] [See also Group V] A method of manufacturing bearing bushings of porous metal consists in mixing together, in powdered form, iron and a metal of lower melting point, with the iron preponderating, adding a small quantity of volatile lubricant, forming the mixture into a briquette by compression, and sintering the briquette in a reducing or non-oxidizing atmosphere. The iron may be sponge iron and the other metal copper or brass. Graphite may be added to the powdered metals. The finished material may be treated so as to harden the iron constituent, or the iron particles may be carbonized before being mixed with the other powdered metal so that the article can be hardened by cooling. The finished material has a coefficient of heat expansion approximately equal to that of iron. A furnace suitable for heating the briquettes is shown in Fig. 1. The briquettes 5 are carried through the oven 2 of the furnace upon a conveyer 3 and ultimately fall into a cooling bath 6. Hydrogen, nitrogen or other gas is supplied to the oven through a pipe 4 and leakage of the gas at the bath 6 is prevented by submerging the walls 7, 8, of the furnace casing in the cooling bath 6. Reference has been directed by the Comptroller to Specification 396,195 (as open to inspection under Sect. 91 of the Acts), [Group XXXII].

Patent GB-586470-A (GB)
Title: Improvements in or relating to the manufacture of aliphatic amines
Filed: 1940-08-07
Abstract: Secondary and tertiary amines are produced by treating an aliphatic alcohol with an excess of ammonia in the presence of a dehydrogenation catalyst, cooling the resultant mixture of nitrile, hydrogen and unreacted substances and passing <PICT:0586470/IV/1> this mixture over a hydrogenation catalyst to convert the nitrile p into a mixture of primary, secondary and tertiary amines. Secondary and/or tertiary amine is or are withdrawn from the production cycle and the other amine or amines are returned to the cycle at convenient points.  The equilibrium which exists in the hydrogenation zone is thus displaced in favour of the production of secondary or tertiary amine.  Some primary amine can also be withdrawn from the production cycle.  Unchanged nitrile, alcohol and ammonia are all returned to the process.  In the Figure, alcohol from tank 1 is reacted with excess of ammonia in the dehydrogenation furnace 3 and in the hydrogenation furnace 7 the nitrile is converted to the corresponding amines.  These are freed from ammonia in the small column 16 and the primary amine is then separated as a head product in column 19 and can be withdrawn or returned to either furnace as desired.  The unchanged nitrile is separated as a head product in column 29 and the alcohol is then similarly separated in column 42 and collected in the tank 47. The secondary amine is next separated as a head product from column 49 and can be withdrawn or sent to tank 47.  The remaining tertiary amine is run into tank 47 or withdrawn as desired.  The contents of tank 47 consisting of alcohol and secondary or tertiary amine are returned to tank 1 to be fed into the production cycle.  In examples: (1) Dibutylamine is made from butanol and ammonia using reduced nickel deposited on kieselguhr and raised to 200 DEG  C. as dehydrogenation catalyst and reduced copper at 180 DEG  C. as hydrogenation catalyst.  The mono- and tributylamines are returned to the furnaces 7 and 3 respectively. (2) Mono- and dibutylamines are prepared simultaneously by using the same dehydrogenation catalyst as in example 1, but with reduced nickel at 100 DEG  C. as hydrogenation catalyst.  The two amines are collected in the proportions desired, all the remainder as well as the tertiary amine being returned into the cycle.  (3) Diethylamine is made from ethyl alcohol and ammonia using reduced copper as catalyst in each furnace, but at 320 DEG  C. in furnace 3 and at 160 DEG  C. in furnace 7.  Diethylamine is withdrawn, all other products being returned to the cycle. Specification 456,952 is referred to.

Abstract: 728,127. Inspecting fabrics. LASZLO, A. Sept. 1, 1952 [May 31, 1951], No. 12909/51. Class 42 (2). [Also in Groups XV and XIX] Apparatus for progressing and inspecting lengths of fabric and for recording faults which may occur on the fabric comprises a machine for progressing the fabric whereon the fabric may be inspected during its travel, and a registering device, ineluding a reduction gear driven from the machine, for progressing a tape, whereon the faults may be recorded, at a greatly reduced speed relative to the speed of the fabric. The registering device shown is attached to the table of a fabric inspection machine and comprises a reduction gear 12 driven from the top roller of the machine. Gear 12 has a ratio of 50 : 1 and drives through belts 14, 28 feed rollers 24, 26. Spring-pressed rollers 23, 25 co-operate with rollers 24, 26 respectively and are releasable by movement of a handle 32. The feed rollers draw a paper recording tape 16 from a feed roll 17 and over a plate 22 when the tape is wound on to a take-up roll 19 driven frictionally from roller 25. In traversing plate 22 the tape passes beneath an aperture 15 in the top surface of the casing 11 of the device. The device is provided with a removable side cover for loading and unloading tape rolls. A braking device may be incorporated to prevent over-running of tape 16. The device can be disposed so that tape 16 moves parallel to, and adjacent the edge of, the fabric passing over the inspection table; or the tape may be arranged to move above the fabric area. In use the inspector marks the paper tape through aperture 15 with pen or pencil whenever a fault appears in the fabric, different symbols being used for different faults; or the pencil may be left resting on the paper to make a continuous line, faults being indicated by sideways movements of the pencil. A datum for marking, corresponding to the point of inspection, may be provided over tape 16 by a fixed ruler or small frame. A carbon copy of the fault record may be made. Different coloured pencils may be used for different faults, or provision may be made for typing appropriate letters or signs on the tape to indicate faults. The tape may have scale markings corresponding to the length of fabric progressed. Where it is desired that a length of marked tape corresponding to a considerable length of fabric be visible, aperture 15 may be larger and the gear reduction much greater, or the tape may be led out of the machine to be wound on a spool some distance away.
