Title: Improvements in or relating to electric sign lamps their arrangement and mounting in groups
IPC: G09F9/307
Filed: 1929-08-22
Abstract: 338,589. Bullen, A.G. Aug. 22, 1929. Monogrammic s i g n s. - Illuminated signs are formed of electric lamps arranged in holders so constructed that the light can be seen from behind through the base of the lamp which is transparent and unobstructed by leads &c. The cap 3 of the lamp 1 has an opening at its end and carries contacts 4 at its side engaging with contacts 5 carried by a base plate 6 in a hole in which the lamp fits. The cap and the hole may be slightly tapered, or a flange 8 prevents the lamp from passing through the hole. A locking ring may be secured on to the base plate and engage a collar on the lamp. The plate 6 may be fitted with a number of holes to receive lamps and letters &c., and may be formed by fitting lamps into the appropriate holes, strip contacts connected to the contacts 5 being embedded in the plate. In order that it may be seen from the back of the plate 6 and from any angle which lamps are alight, lenses may be placed at the back of the openings in the plate, the lamps being then inserted from the front.

Title: Process and apparatus for effecting the hydrogen enrichment of hydrogen-containing gas mixtures
IPC: F25J5/00
Filed: 1965-06-17
Abstract: 1,041,964. Cold separation of gas mixtures. LINDE A.G. June 17, 1965 [June 18, 1964], No. 25593/65. Heading F4P. In a process for increasing from about 50 to 95% the hydrogen content of a gas mixture containing hydrocarbon and other gases which are condensed in at least one of a group of at least three cyclically interchangeable regenerators 1, 2 and 3, Fig. 1 (not shown), or reversible heat-exchangers from which the condensates, e.g. methane, carbon monoxide and carbon dioxide are at least partially evaporated by a flushing gas at a reduced pressure effected by a blower 23 during a second phase of the cycle and the regenerator so purified is re-cooled during a third phase of the cycle, at least part of the hydrogen-enriched mixture leaving the first phase regenerator is heated, expanded at a turbine 24 and passed through the regenerator which was freed in part of condensates during the previous phase of the cycle. In operation feed mixture is expanded from 30 to 10 atmospheres pressure in an engine 21 into a line 11 connected to the regenerators and part of the purified hydrogen mixture leaving, say, regenerator 1 through a line 4 is branched off at 5 and wound in a coil 6 in the regenerator 1 returned at 7 to the main stream 8 which after expansion at turbine 24 is passed through a line 17 to regenerator 2 to effect recooling thereof and is passed through a line 12 and a compressor 22 to an outlet 14. During the flushing period between 1 and 6% of the purified hydrogen is withdrawn from line 8 and is fed through a line 10 to the regenerator 3 being flushed at a pressure of about 0À5 atmospheres maintained by blower 23. In a modification and assuming no hydrogen sulphide in the feed mixture, line 10 is closed and regenerator 3 is flushed at a pressure of 0-2 atmospheres and residual methane is re-evaporated during the succeeding cooling period. In a further modification a portion of warm product hydrogen leaving compressor 22 is withdrawn at 14 and passed to the inlet of turbine 24; the heating coil 6 being dispensed with.

Abstract: Process for the preparation of sulphonated disazo dyes of the general formula: <IMAGE>  in which     X = -H, -CH3, -OCH3, -Cl, -SO3M or -NO2;   Z = -H or -CH3;   Y = -H or -SO3M;   the group SO3M is in the 6- or 7-position, K = lower alkyl having 1 to 4 carbon atoms or -CH2-CH2-SO3M if Y is hydrogen;   M = -H, -Na, -K or -NH4, obtained by coupling the diazonium salt of an optionally substituted aniline with a naphthylamine sulphonic acid, diazotising the compound thus obtained and finally coupling with a benzylaniline substituted in various ways. Such dyes are particularly used in the dyeing of nitrogenous fibres, where they give rise to shades varying from red to violet, with very good general fastness properties, affinity and levelness. They have the fundamental and determining advantage of not involving the use of  alpha -naphthylamine in their preparation, unlike other dyes of similar structure which require particular care and precautions due to their noxious toxicological properties.
