Title: Improvements in and relating to systems for cooling of air for example for aircraft pressurised spaces
Inventor: HEBDEN GEOFFREY PATRICK
IPC: B64D13/06
Filed: 1955-03-09
Abstract: 773,248. Air cooling installations; refrigerating. NORMALAIR, Ltd. March 9, 1955, No. 6893/55. Classas 29 and 64(3) Air is cooled by heat exchange first with air and then with water which is evaporated. In the apparatus shown, compressed air supplied to an aircraft cabin 22 is cooled first in a cooler 14, then in an indirectcontact heat exchanger 3 in which it heats water and converts it into steam which escapes to the atmosphere, then in a cooler 5, and finally by driving a turbine 20. Exhaust air from the cabin 22 flows, under the action of a fan 23 driven by the turbine 20, through the coolers 5, 14 to act as coolant. In the heat exchanger 3, the air flows through coiled tubes 16 immersed in water and connected to headers 17, 18. In the form shown, two air-cooling systems supplied by separate engine compressors are interconnected through a shut-off valve 15, so that if one engine.or air supply duct is damaged the compressor of the other engine can supply both systems. Bypasses for the turbines 20 and coolers 5 may be regulated by valves 25, 34 which are either manually operated or, as shown, operated by pistons 26 acted on by, springs and pneumatic pressure from air bled from the cabin supply ducts after leaving the heat exchangers 3. Bimetallic elements 31, 32 in the inlet and outlet ducts of the cabin regulate needle valves. 29, 30 controlling the leakage of the bled air, and so control the air pressure on the pistons.

Title: Coated nuclear fuel particles
IPC: G21C3/62
Filed: 1971-03-15
Abstract: 1378501 Nuclear fuel UNITED KINGDOM ATOMIC ENERGY AUTHORITY 14 March 1972 [15 March 1971 28 July 1971] 6907/71 and 35554/71 Heading G6C The kernel of a coated nuclear fuel particle comprises an oxide of uranium, thorium, or plutonium together with an oxide of a metal of variable valency, e.g. cerium, terbium, or praseodymium, which acts as a stabilizer. The stabilizing oxide is at least partially in its lower valency state and reacts, during fission, with released oxygen, thus preventing reaction of the oxygen with coating material, e.g. pyrolytic carbon. The added oxide may be distributed throughout the fuel oxide. In examples, the kernels are made by powder agglomeration or by gelation of sol droplets; ceric oxide which has been added is reduced to cerous oxide by heating in an argon-hydrogen mixture, and the kernels are stored in a non-oxidizing atmosphere until required for coating.

Abstract: 1495455 Grooved cylinders and follower units TOYODA JIDOSHOKKI SEISAKUSHO KK 19 Feb 1975 [25 Feb 1974] 6930/75 Heading D1J The invention relates to an apparatus of the kind in which a yarn package 3 is driven by a friction roller 4 and the yarn 1 is traversed by a follower 10 sliding in an endless helical guide groove of a rotating cylindrical cam 6, the cam 6 being housed in a cam box 7 that carries opposed guide rails 8, 9 between which the follower 10 slides. According to the invention the cam box 7 is supported such that it can be turned about the longitudinal axis of the cam 6 there being means for locking the box 7 at a first position Fig. 2, in which the rails 8, 9 face the friction roller 4; and at a second position, Fig. 5 where the rails 8, 9 face away from the friction roller. The box 7 carries a stop 7c. In Fig. 2 the stop 7c abuts a fixed stop 15a and piston and cylinder unit 22 engages in a recess 7d in the box 7 to hold the box in this setting. In Fig. 5 the stop 7c abuts a fixed stop 15b and the piston and cylinder unit now engages in a recess 7c in the box 7. The cam 6 has at least one pair of helical endless guide grooves in its surface, Fig. 4 (not shown) there being a ring-shaped guide groove (25) between each pair of helical guide grooves; and an auxiliary guide groove (29a, 29b) connecting each helical groove to the ring-shaped guide groove (25). The turnable box 7 and the ring-shaped guide groove (25) facilitate the changing of the followers 10 when they become worn.

Title: Dyestuffs containing urethane and thiourethane groups
IPC: C09B62/00
Filed: 1961-02-24
Abstract: The invention comprises dyestuffs of the general formula <FORM:0924534/IV(a)/1> wherein F denotes the radical of organic dyestuff and R is <FORM:0924534/IV(a)/2> or -SCH2-COOR1 where "halogen" stands for a halogen atom, preferably chlorine or bromine, R1 is a carbocyclic aromatic or aliphatic radical, X- is a colourless anion and n represents a whole number.  The dyes may be of the azo, azomethine, nitro, stilbene, anthraquinone, triphenylmethane, oxazine, dioxazine or azaporphine series.  They may contain higher condensed ring systems such as benzanthrone and dibenzanthrone and where they contain metal-complex forming groupings may be used in the form of metal complexes, e.g. copper, cobalt, chromium, iron and nickel complexes.  Metal free- or cobalt, copper and nickel phthalocyanines may be employed.  The specified urethane groupings may be introduced into the dyes by known methods, e.g. by the reaction of free amino group containing dyes with appropriate chloroformic acid esters or thioglycollic acid esters.  Alternatively the urethane radicals may be introduced into dyestuff precursors which may then be converted to dyes, e.g. by diazotization and coupling.  The urethane groups may be linked to the nucleus of the dyestuff radical directly or through a bridge member, e.g. aliphatic or cycloaliphatic radicals, -SO2NH-aryl-, -CO,NH-aryl-,-SO2-NH-(CH2)x and -CO-NH-(CH2)x.  Additional substituents specified include, sulphonic and carboxylic acid, sulphonamide, sulphone, disulphimide, alkyl, alkoxy, halogen, aryl or alkylamino, nitro, cyano, sulphuric semi-ester, hydroxyalkyl-sulphone- or -sulphonamide groups, mono- or dichlorotriazinylamino-or -amido, mono-, di or trichloropyrimdinyl-amino- or -amido, epoxide, b - or g -chloroalkyl or acylamino, isothiocyanate, sulphofluoride and vinyl sulphone groups.  Among the many dyes of which the preparation is described in examples are those prepared from 1-amino-4-[p-aminohexahydroanilino]-anthraquinone-2- sulphonic acid and chloroformic trichloroethyl ester; benzene-2-sulphonic acid -[1-azo-71]-2-amino-81-hydroxynaphthalene-31, 61-disulphonic acid and chloroformic b -bromallyl ester; copper-phthalocyanine-3-disulphonic acid -3-di-(31-amino-41-sulphophenyl)-sulphonamide and chloroformic 2-bromallyl ester and the azodye, 1-amino-benzene-4-sulphonic acid-->1-(41-aminophenyl)-3-methyl-5-pyrazolone, and chloroformic-2-chlorallylester.  The dyes are employed in the dyeing or printing of hydroxyl group-containing materials, e.g. cotton and regenerated cellulose and synthetic polyamides and are fixed to the material by a combination of heat- and alkaline-treatment.

A second transistor T 1  is constructed so that it passes a current proportional to the collector current of transistor T 0 , and is connected so as to control the output current of a current mirror T 2 , T 3 . This current, which is proportional to the current carried by transistor To, is fed to terminal 3 forming the connection between resistors R a , R b  which comprise a voltage divider across the output supply V out . It is shown that the voltage V out  increases linearly with the output current I out . The system may be used to supply a small D.C. motor.
