Title: Improvements in the manufacture and production of nitrogenous condensation products
IPC: C07D221/18
Filed: 1933-03-11
Abstract: Pyridino compounds of pyrene or chrysene are subjected to an oxidizing treatment in acid media, and if desired, the products so formed are halogenated.  Chromic acid is preferably used as oxidizing agent and quinones are formed, which may be purified by the usual methods.  In examples: (1) dipyridinopyrene (prepared by nitrating pyrene in nitrobenzene, reducing and converting the diamino body by Skraup synthesis) is treated with bichromate and sulphuric acid to give a greenish-yellow dyeing quinone; dimethyldipyridinopyrene (prepared according to Doebner and Von Miller synthesis from diaminopyrene) may be similarly treated; (2) monopyridinopyrene (prepared by a Skraup synthesis on monaminopyrene) is treated in glacial acetic acid with chromic anhydride to give an orange-yellow dyeing quinone; on brominating this in nitrobenzene in presence of iodine and iron a yellow vat dye is obtained; by action of sulphuryl chloride on the quinone a yellow dye is also obtained, and halogenation may also be carried out in chlorsulphonic or sulphuric acids; (3) dipyridinochrysene (prepared by nitrating chrysene in nitrobenzene, reducing and converting the diamino compound by a Skraup synthesis) is oxidized as in (2) to give a reddish-yellow dye. Specification 349,059 is referred to.  The Specification as open to inspection under Sect. 91 relates to the introduction of substituents into the oxidized products and mentions nitro and amino substituting groups.  This subject-matter p  does not appear in the Specification as accepted.
Patent GB-905924-A (GB)
Title: Improvements in and relating to the control of the cooling water system of condensers, for example in a steam turbine plant
Inventor: WATSON HENRY
IPC: F16K11/085
Filed: 1960-03-02
Abstract: <PICT:0905924/III/1> <PICT:0905924/III/2> In a condenser system of the type wherein steam is condensed by direct contact with sprays of cool water, the warm water discharged from the condenser 30 (Fig. 6) is cooled by indirect heat exchange with air, the heat exchanger comprises several sectors 42 each associated with a plug valve having six ports; one pair of ports 6, 9 (Fig. 4) can be connected to the associated heat exchanger sector, another pair 4, 7 can be connected to a water storage tank 48, one port 5 of the third pair can be connected to the spray nozzles of the condenser and the other port 8 can be connected to the water circulation pumps 37.  The individual heat exchange sectors are readily put into, or taken out of, service. The ports 5 are connected to the spray nozzles of the condenser via manifold 40, hydraulic turbines 33, and pipes 32.  The outlets from the bottom of the condenser lead to pumps 37 which are connected to manifold 35 and the ports 8 of the valves. Pumps 37 are partly driven by turbines 33 and partly by electric motors 43.  When a particular heat exchanger sector is in service, the plug is adjusted so that ports 8, 9, 6, 5, are open; and this permits water to flow from manifold 35 into the sector, and the cooled water to be discharged from the sector into manifold 40. In order to empty the sector quickly, the plug is adjusted so that ports 6, 7, 9 and 4 are open (ports 5 and 8 being closed), in order to connect the sector with pipe 44 and tank 48.  To refill the sector, the plug is in the position shown in Fig. 4, whereby water flows from manifold 35 through port 8 and the internal duct 23 in the plug to port 6 and thence through pipe 46 to the sector, and water also flows past the chamfered edge 22 of the plug to port 9 and pipe 49 and thence to the sector.  By-pass valve 41 permits, if opened, part of the water from the manifold to return directly to the spray nozzles of the condenser, without passing through the heat exchanger, whereby the temperature of the water sprayed into the condenser can be matched to the actual requirements of the operation.  Water is supplied to the condenser from tank 48 via valve 55, when the water level in the condenser drops below a predetermined minimum.

Title: Improvements in autographic registers
IPC: B41L5/04
Filed: 1923-03-15
Abstract: 218,713. Imray, O. Y., (American Sales Book Co., Ltd.). March 15, 1923. Memorandum appliances.-In an autographic register in which the record strips are aligned by the engagement of pins with registering apertures in the strips, a member carrying the pins is reciprocated across the strips through a toothed segment on a hand oscillated member which also serves through another toothed segment to actuate the feed rollers. The strips are fed by positively geared rollers 31, 36 from rolls 7<a> over a writing surface 8 where carbon sheets are interposed between them. The ends of the roller 36 are carried by two vertically slidable plates 39 and are spring- pressed toward the roller 31. Two guide openings 56, 57 are provided adjacent to the delivery side of the feed rollers and are formed bv two cross-bars 52, 53, and a central guide plate 50 carried bv side plates 51. The lowest strip passes through the opening 57 into a filing chamber and the other strips pass through the opening 56 of the machine. Rotation of the feed rollers is effected through a ratchet mechanism from a toothed segment 128 carried by a hand-oscillated member 126. When the segment 128 passes out of engagement with the feed-mechanism, a part 133, carried on the segment 128, prevents further rotation of the feed rollers by engaging the locking teeth 136, 137 carried by the pinion 129, and a second toothed segment 127 on the member 126 engages a toothed segment 23 on a shaft 22, so as to cause a crank 24 on the shaft 22 to engage projections 25 on a vertically movable member 16. The member 16 carries the alignment pins 100, a severing knife 58 and a filing pin 73. When the member 16 is moved upward, the pins enter apertures in the strips and at the same time the feed rollers are separated by a tappet 105 on the member 16 engaging and lifting the plates 39, so that the backward pull on the strips serves to align them. The knife 58 cooperates with the bar 52 to sever the used record strips and the filing pin 73 pierces the lowest strip which has passed into the filing chamber. An extension 55 of the guide plate 50 is slidably mounted between the side plates 51 and is moved out of the path of the knife as it passes upward by a projection 63 on a shaft 62 rocked by the engagement of the upper end of the knife with a second projection 66 thereon. The length of the strip fed at each oscillation of the member 126 is regulated by an adjustable stop 139 which determines the initial position of the segment 128. The roller 36 mav be lifted independently of the member 126, if desired, by a hand-operated shaft having cam surfaces engaging the lower edges of the plates 39.

Abstract: 988,347. Endless belt conveyers. PROSPECT MANUFACTURING CO. Inc. Feb. 24, 1964, No. 7598/64. Heading B8A. Articles are passed to a conveyer for subsequent delivery to any of a plurality of preselected stations by apparatus comprising (Figs. 1, 4) a main belt 10 passing articles to deflectors 12, 14 and down a slide 16 to transfer belts 20, 21 which deliver the articles to tables 22, 23. Each table 22, 23 has an associated photo-cell 26, the interruption of the associated light beam stopping the associated belt to prevent articles piling up on the table. A pair of delivery belts 24 is associated with the tables 22, 23 and each delivery belt 24 has an associated article detecting photo-cell 28. An operator checks the destination of an article on a table (say 22) and codes it by means of a control unit (not shown). The article is then placed on the belt 24 and is carried at low speed until it is detected by the photo-cell 28 which acts to stop the belt 24. A conveyer comprising tilting trays 52 passes the delivery end of the belt 24 and as a tray 52 comes into position opposite the delivery end of the belt 24 it mechanically actuates a switch to energize a solenoid 42 associated with belt drive means 40 to cause the delivery belt 24 to operate at high speed to pass the article to the tray 52. Simultaneously, the control means transfers the delivery code to the conveyer so that the tray 52 dumps the article at the assigned station. Fig. 3 shows an embodiment wherein the delivery belt 24 is replaced by a delivery belt 56 mounted on a carriage running on tracks 62. Movement of the carriage is synchronized with the high speed drive of the delivery belt so as to move alongside the tray 52 whilst the article is passed thereto. The apparatus may be used in sorting postal articles.

Abstract: 527,767. Isomerization of paraffinic hydrocarbons. I. G. FARBENINDUSTRIE AKT.- GES. March 14, 1939, No. 1189. Convention date, March 15, 1938. [Class 2 (iii)] Paraffinic hydrocarbons of from 4-12 carbon atoms are isomerized, by passage with hydrogen over an absorbent or hydrogenating or dehydrogenating catalyst at between 200‹-600‹ C. and at a pressure exceeding 100 atmospheres, the partial pressure of the hydrogen being less than 5 per cent of the total pressure. The preferred temperature range is from 350‹ C.-500‹ C. and the preferred pressure 200 atmospheres or more. The preferred catalysts are absorption agents or sulphidic or oxidic hydrogenation or dehydrogenation catalysts, which should not be reducible under the conditions used, such as chromium oxide, sulphides of the heavy metals of the 6th to 8th groups of the periodic system, used either alone or mixed with other substances. Pure metallic catalysts may also be used but are less suitable. The life of the sulphide catalysts may be prolonged by using initial materials containing a small amount of sulphur. As absorption agents there are used materials with a large surface, such as alumina silica gel, and zinc oxide. These compounds are particularly useful when the hydrogen used contains traces of halogen. Active carbons and silicates may also be used. In examples (1) normal hexane is passed at 410‹ C. at 220 atmospheres with 1 per cent of hydrogen containing a little hydrogen sulphide over active carbon which has been impregnated with ammonium thiomolybdate solution and dried in a current of carbon dioxide. The product is cooled under high pressure to give a liquid boiling mainly between 35‹-69‹ C. (2) Liquid normal butane containing a small amount of organically combined sulphur is passed over pieces of tungsten disulphide at 420‹ C. at 240 atmospheres together with hydrogen. By cooling at high pressure as before a mixture of normal and isobutane is obtained. (3) Isobutane is treated as in example (2) to give a mixture of normal and isobutane.
