Title: Improvements relating to the production of seamless hollow bodies by dipping
IPC: B29C41/14
Filed: 1938-08-16
Abstract: 518,169. Moulding by dipping. BRATRING,. K., and INTERNATIONAL CONTAINERS, Ltd. Aug. 16, 1938, No. 24106. [Class 87 (ii)] In moulding hollow-bodies by dipping cores 2 in solutions of cellulose derivatives or other plastic material, the temperature above the surface of the solution is maintained lower than that of the solution itself so that as the coated cores are withdrawn, they emerge into the zone of lower temperature. In some cases the coated cores are subjected to an atmosphere at a temperature lower than that of the solution and are subsequently dried at a higher temperature. A 15 per cent. solution of cellulose acetate may be maintained at 30 to 35‹C. and a drying chamber above the solution at 25‹C. The coated cores may subsequently pass through separate chambers at 35‹C. and 40 to 45‹C.. Cores 2 may be moved intermittently by a belt 3 through chambers 6, 7. A dipping bath 10 is mounted within a chamber 9 on a lifting device within the chamber 6. The chamber 9 is. provided with a closure flap 11 and is heated by tubes 15. The chamber 6 is provided with heating and cooling tubes 13, 14 which circulate the air and maintain the required temperature. In use, the chamber 9 is raised to immerse the cores as the belt is stationary. After dipping, the cores pass to the drying chamber 7 heated by tubes 16. The chambers 6, 7 are provided with gas-tight doors which close when the belt is stationary.

Title: 1,4-dihydropyridine
IPC: C07F7/10
Filed: 1966-05-10
Abstract: The subject matter relevant to this heading is the same as that in parent Specification 1,112,566.ALSO:Novel 1,4-dihydropyridine is prepared by reacting pyridine and an SiH compound in the presence of palladium, rhodium, nickel, platinum, iridium or ruthenium as a catalyst, to form a compound in which the nitrogen atom has an organo substituted silyl group attached directly thereto and removing said organo substituted silyl group to obtain a reaction mixture including 1,4-dihydropyridine.  The organo-substituted silyl group is removed by reaction with, for example, methanol, water, ammonia and phosphines.  The SiH compound can either be a silane R3SiH where R is an organoxy or monovalent hydrocarbon radical or a polysiloxane containing silanic hydrogen. Many examples of suitable SiH compounds are given (see Division C3). In an example, trimethyl silane is reacted with pyridine in the presence of palladium to yield a mixture of trimethyl silyl substituted hydropyridines from which 1-trimethyl silyl dihydro pyridine is obtained by fractional distillation and reacted with methanol to give 1,4-dihydropyridine. 1,4-Dihydropyridine undergoes vinyl polymerization and polymerization by N-H addition (see Division C3).

Filed: 1946-08-21
Abstract: 642,368. Radio navigation. O'BRIEN, W. J. Aug. 21, 1946, No. 24987. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 28, 1947.] [Class 40 (vii)] In an equi-phase difference contour radio navigation system, having three spaced transmitters, two of the transmitters radiate signals of different but harmonically related frequencies in fixed phase relation and the third radiates two other different frequencies harmonically related and in fixed phase relation to each other and to the signals from the other transmitters. At the receiver two signals of like frequency, one from the signals from the third transmitter and the other from the other two signals, are derived and compared in phase. Neglecting one of the signals from the third transmitter the system becomes similar to that described in Specification 620,479 and a receiver for such a system may be used to give an accurate position determination. However, by using all four signals a less accurate but less ambiguous determination of a single positional co-ordinate may be made at a phase comparison frequency lower than in the prior system. The transmitter radiating two frequencies may, in one embodiment, be placed on the line joining the other two and operated as a master transmitter having two oscillators of, say, 60 and 70 kc. feeding the antenna, the oscillators being interlocked to provide a fixed frequency ratio and phase relationship. The other two stations may be slave stations such as described in the above-mentioned Specification radiating respectively 80 kc. and 90 kc. signals, frequency and phase locked to the 60 kc. signals which they receive from the master station. At the receiver all the signals are received on a common antenna 8 and separated into four different channels 9, 10, 11 and 12 tuned to the individual frequencies. The two signals of 60 and 70 kc. received from the master transmitter are derived at 13 from channels 9 and 10 and the 10 kc. beat frequency applied to phase discriminator 14. The other input to the discriminator is the beat frequency of the 80 and 90 kc. received signals derived at 15 and the discriminator output drives phase indicator 16. Specifications 25491/46 (as open to inspection under Sect. 91), 620,480, 620,481, 620,507, and 642,398 also are referred to.

Abstract: 1513703 Locating defective fuel rods BABCOCK-BROWN BOVERI REAKTOR GmbH 17 June 1976 [26 June 1975] 25164/76 Heading G6C In a method of locating defective fuel rods of a fuel element of a water-cooled reactor whilst the rods are assembled in the fuel element, the fuel element 4 is removed from the reactor and inserted in a water-filled pressure vessel 3 which is then pressurized to a predetermined value, and sound waves emitted by each individual fuel rod 17 are detected in order to obtain an indication of water penetration into each rod. In one embodiment, Fig. 1, one of the end members 5 of the fuel element 4 is removed and the fuel element then rests within the pressure vessel 3 upon a support 6 provided with cavities 7 for locating the other end member 5. The pressure vessel 3 is closed in a pressure-tight manner by a cover 2 to which there are secured, by means of intervening compression springs 12, a number of sound emission detectors 13 equal to the number of fuel rods 17. Each sound emission detector 13, Fig. 2, is preferably so constructed that the apex angle of its cone is larger than that of the cone of the fuel rod end 21. By means of a pump (not shown) the pressure in the vessel 3 is raised via a pressure line 15 to a level equal to that existing within the reactor when in operation. The detectors 13 now receive sound waves of different intensities according to the different stress conditions existing in the undamaged cladding tubes and in those tubes into which water has penetrated, the resultant signals being transmitted via lines 16 to an evaluation point, which can be arranged at the central control position of the reactor power plant. Furthermore, on the basis of the turbulence noises generated during the phase when the pressure is being built up in the vessel 3 and resulting from the flow of water through the leakage points in the defective fuel rods, determinations can be made of the magnitude of the leakage. In an alternative embodiment (Figs. 3 and 4, not shown) in which removal of a fuel element and member 5 is not necessary, a single sound emission detector 13 is situated externally of the pressure vessel 3 and is connected via a sound transmission conductor (22) and a contact member (23) with a particular fuel rod under test. A non-metallic, preferably resilient, sound insulating member (24) prevents the transfer of secondary noise from an adjacent fuel rod serving as a support abutment for the contact member (23). The sound emission detector 13 is moved sequentially from one fuel rod to the next.

Abstract: 1318703 Continuous casting; working at specified temperatures VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE AG 26 May 1970 [30 May 1969] 25286/70 Headings B3F and B3V In a continuous slab-casting machine, when a water-cooled mould 1 is released and raised (as indicated in broken lines) out of a frame 2 in which it is mounted, an upright part 3 of the casting guide of a secondary cooler with a curved portion 6 can be lifted out through the frame 2; there is a curved part 7 of the guide, which is displaceable horizontally, followed by a withdrawing and straightening unit 12. The distance h between the surface of the metal in the mould 1 and the bottom of the vertical part of the guide and secondary (spray) cooler is 1À0-4À0 m. Two ladles 28 and two tundishes 30 are supported on slewable arms 24-27 and the tundish arms 26, 27 may be displaceable along a column 22 to immerse the tundish spouts in the mould 1. There are connections between the mould 1 and frame 2 for the cooling-water and for interfixing. The frame 2 is reciprocated together with the mould 1 and two pairs of rolls fixed to the latter. The curved guide-part 7 (whose rolls 8 may be of different diameters) may be replaced by guide 20 which includes a non-cooled portion 21 which allows equalization of the temperature over the strand cross-section. Alternatively, there may be a non-cooled unit between the guide-part 7 and the withdrawal and straightening stand 12. The latter also rolls the strand 11. The equalizing of the temperature is applied to rimming-steel strands. The stand 12 has a guide roll 15, rolls 13 (which, if they do not merely withdraw the strand, reduce the strand up to 30%) and straightening rolls 14 which may also exert pressure on the strand. The strand 11 may be reduced, if there is no temperature equalization, by the rolls 13 while it has a hotter core (greater than 900‹ C.,e.g. 1200-1300‹ C., compared with a surface temperature of 800-1000‹ C.) which therefore is primarily worked. This results in improved quality when there is subsequent rolling to obtain plates.
