Filed: 1972-03-22
Abstract: 1393434 Treating effluent; heavy water DEUTERIUM CORP 22 March 1972 [22 March 1971] 13481/72 Headings C1A and C1C In a process for producing heavy water in a dual temperature exchange system in which H 2 S gas and water are contacted at elevated temperature and pressure, water, prior to being fed into the system, is heated by heat-exchange with effluent discharged from a hot tower of the system and saturated at elevated temperature and pressure with H 2 S gas from a cold tower of the system. In the embodiment shown, hot effluent from a hot tower (not shown) is passed via line 8A to flash evaporators 26-23. The resultant H 2 S gas is treated with cold water to condense water vapour contained therein and the H 2 S gas is returned to the system via line 7A, which line includes compressors 40-42. The remaining H 2 S in the hot effluent is stripped by steam in stripper 22, treated with cold water, compressed and returned to the system. The effluent, after treatment in the stripper 22, is passed to steam flash evaporator 18, part of the produced steam being used in stripper 22. The sea water being fed to the system from line 3A is passed via hydrocyclone 10 and deaerator 11 to heat exchanger 16 comprising a plurality of units connected in series and in parallel, in which it is heated by effluent from evaporator 18. The feed water is then further heated by direct contact with steam produced in the evaporator 18 and then saturated in saturator 21 with H 2 S gas from a cold tower of the system, supplied through line 9A.

IPC: C09B56/04
Filed: 1933-05-10
Abstract: Stilbene dyes; monoazo dyes.--New azo dyestuffs of the stilbene series are obtained by subjecting to the action of alkaline reducing agents and of oxidising agents, in either sequence, the dyestuffs obtained by condensing with aminoazo compounds (a) 4 : 4<1> - dinitrostilbene-2 : 2<1>-disulphonic acid, (b) 4 : 4<1>-dinitrodibenzyl-2 : 2<1>-disulphonic acid, or (c) a product of the alkaline conversion of 4-nitrotoluene-2-sulphonic acid.  The products give orange to red dyeings which, as compared with those from the parent dyestuffs, are redder and brighter and of enhanced fastness, especially to chlorine and to light.  The following examples are specified.  (1) The product of condensation in alkaline solution of 4 : 4<1>-dinitrostilbene-2 : 2<1>-disulphonic acid with 4-aminoazobenzene-4<1>-sulphonic acid is heated for \ba1/2\be hour at 70--80 DEG  C. with an alkaline solution of sodium sulphide, whereupon sodium hypochlorite is added and heating continued for \ba1/2\be hour at 80--90 DEG  C.; the solution is then neutralised and the dyestuff is salted out; the product dyes cotton, from a bath alkaline with sodium carbonate, clear orange shades fast to chlorine and to light.  (2) The product of alkaline condensation of 4 : 4<1>-dinitrostilbene-2 : 2<1>-disulphonic acid with 2 - methyl - 4 - aminoazobenzene - 2<1> - sulphonic acid is heated for 3--4 hours at 80--85 DEG  C. with an alkaline solution of dextrose; the solution is then neutralised and the product salted out and heated for \ba1/2\be hour at 80--90 DEG  C. with a solution of sodium hypochlorite; the product, separated as in (1) dyes cotton redder and purer full orange shades than are obtained with the parent dyestuff; the shades are also of greater fastness to chlorine and to light.  (3) Similar products are obtained when the aminoazo compound in (2) is replaced by 2-methyl-5-methoxy - 4 - aminoazobenzene - 2<1> - or 4<1> - sulphonic acid or 2 - methyl - 5 - methoxy - 4<1> - ethoxy - 4 - aminoazobenzene - 2<1> - sulphonic acid.  (4) The products of condensation of 4 : 4<1> - dinitrostilbene - 2 : 2<1> - disulphonic acid with aminoazo compounds of the type, an anilinesulphonic acid or a homologue thereof --> an aminohydroquinone-dialkylether, such as 2 : 5-dimethoxy - 4 - aminoazobenzene - 4<1> - sulphonic acid, are reduced and oxidised as in (2).  (5) The reduction and oxidation of example (1) are effected in the reverse order.  (6) The product of alkaline condensation with 4-aminoazobenzene-4<1>-sulphonic acid of the product of reaction of caustic soda lye on p-nitrotoluenesulphonic acid (cf. Specification 22555/09, [Class 2 (iii), Dyes &c.]) is reduced by warming with sodium sulphide solution and the product is oxidised with sodium hypochlorite or chlorine in an alkaline medium.  (7) The products of condensation of 4 : 4<1>-dinitrostilbene-2 : 2<1>-disulphonic acid (1 mol.) with aminoazo compounds such as 2-methyl-4-aminoazobenzene-4<1>-sulphonic acid (2 mols.) are similarly reduced and oxidised.

Title: Improvements in or relating to record player change speed gears
IPC: F16H15/46
Filed: 1957-05-01
Abstract: 823,310. Change-speed gear. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 1, 1957 [May 4, 1956], No. 13891/57. Class 80 (2). [Also in Group XXXVIII] Relates to a gramophone change-speed gear of the type comprising a stepped driving-wheel 4 engaged by a friction idler disc 2 mounted on a lever 5 supported on a bracket 6 pivoting on a shaft 8, the idler disc 2 engaging the rim of a turntable 1. A spring 3 biases the idler disc 2 to engage the stepped driving wheel 4 and the turntable rim. A flange 11 on the bracket 6 is adapted to be engaged by a coned disc 13 when a push-button 12 is depressed. Such operation of the push-button 12 causes the coned disc 13 and flange 11 to coact in such a way that the bracket 6 &c. is first turned slightly against the bias of the spring 3 to disengage the idler disc 2 from the steps on the driving wheel 4. Further depression of the push-button then forces the bracket 6 downwardly of Fig. 3 against the bias of a spring 10 on its supporting shaft 8. The bracket 6 is formed with a curved indexing plate 15, Fig. 1, having an aperture 16 shaped as shown in Fig. 6, and co-operating with a pin 17 passed transversely through the shaft 8. Downward movement of the bracket 6 and the indexing plate 15 causes the upper edge of the aperture 16 to coact with the pin 17 and turn the shaft 8 anti-clockwise of Fig. 1. On releasing the push-button, the bracket 6 &c. is pushed upwardly by its spring 10 so that the lower surface of the aperture 16 re-engages the pin 17. The lower surface 18-20 of the aperture 16 is so shaped that the bracket 6 &c. returns to a different position axially of the shaft 8. Accordingly the idler disc 2 engages a different step on the driving friction wheel 4, and the gear gives a different ratio. When one end of the pin 17 leaves the end 20 of the aperture 16, the other end of the pin enters the opposite end of the aperture. A speed indicating disc 24 is secured to the end of the shaft 8. As a modification, the pin 17 may be arranged to be moved initially against spring bias, the indexing plate then turning on release of the pushbutton.
