Abstract: 957,806. Oil break switches; mechanical switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 31, 1962 [Jan. 15,1962], No. 1434/62. Heading H2B. A change-over switch immersed in oil in a tank 15 has main and auxiliary roller contacts 11, 24 mounted on copivotal arms 12, 26 having a lost-motion coupling between them and engaging spring-urged fixed contacts 17 or 17<SP>1</SP> and 25 or 25<SP>1</SP> respectively. The switch is operated through an overcentre toggle linkage 21, 22 operating on the main contact arm 12 directly and the auxiliary contact arm 26 through the pin and slot coupling 23, 27. The surfaces of the auxiliary contact rollers 24, 25, 25<SP>1</SP> is of arc resistant material. In a transformer tap-changing switchgear (Fig. 2, not shown) two such change-over switehes are operated in sequence, by a common shaft 20, as a diverter switch. A modification involves the use of spring-loaded butt contacts in place of the rollers &c.

Title: Improvements relating to refractory products
IPC: C04B35/48
Filed: 1936-01-17
Abstract: A refractory product is prepared by calcining a mixture of zircon and one or more refractory metal oxides (e.g. magnesia, alumina) capable of combining with vitreous silica, the oxide or oxides being in such quantity that all the silica which results from the decomposition of the zircon, when heated at a temperature of at least 1500 DEG  C. but without fusion, will combine therewith.  The quantity of oxide added may be sufficient to combine with all the silica which would result from total decomposition of the zircon.  In an example, a mixture consisting of 40 to 20 per cent of zircon and 60 to 80 per cent of natural corundum, with perhaps a little clay, is pressed and calcined at about 1600 DEG  C.  As grog may be used the product of the process set forth in Specification 429,367.  Reference has been directed by the Comptroller to U.S.A. Specifications 1,952,119 and 1,952,120.

Abstract: 1319032 Measuring semi-conductor impurity concentration WESTERN ELECTRIC CO Inc 13 Jan 1971 [19 Jan 1970] 1619/71 Heading G1U The deep impurity concentration in a semiconductor wafer 12 is determined by forming a depletion layer in the wafer, using a Schottby diode 13 reverse-biased from a variable D.C. source 18, applying an alternating current signal from a source 20 to the diode, developing across the wafer a voltage of the frequency of the second harmonic of the frequency of the applied signal and, determining the phase difference in a detector 26 between the derived second harmonic voltage and a second harmonic voltage derived from a frequency doubler 30 connected to the source, which phase difference is proportional to the concentration of deep impurities at the edge 19 of the depletion layer and is displayed on on XY recorder 28. As disclosed in Specification 1269263 (see Division G1) the depth of the depletion layer is proportional to the amplitude of the fundamental voltage developed across wafer which is derived by a filter 27 and applied to the X-co-ordinates of the X-Y recorder, the Y co-ordinate being fed from the phase detector 26 to record deep impurity concentration vs. depth. The edge 19 of the depletion layer is caused to move through the wafer by variation of the voltage from source 18. A combined apparatus for measuring deep impurity concentration as above and doping density profile as described in the above-mentioned specification is illustrated in Fig. 3 (not shown) where the amplitude of the second harmonic voltage developed across the wafer 13 derived by a received 37 which amplitude is proportional to the shallow impurity concentration at the edge of the depletion layer.

Abstract: 174,359. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Wilson, G. P.). Jan. 20, 1921, [Convention date]. Protective arrangements for electrically-driven apparatus such as rolling mills comprising a ground relay 15 which, through the time-lag relay 33, trips the main circuit-breaker 4 after a delay which is greater than the time taken bv the work to pass through the rollers, as described in Specification 169,152, are provided with an additional relay 28 in the tripping circuit energized by the motor current to prevent tripping while the mill is operating. The additional relay is moved to the open position by the core of a winding 29 energized from the current transformers 9, 10, 11 and is held by a latch 31, thereby maintaining the tripping circuit open even if, after the imposed delay, it is closed by the relay 33. If an earth develops, for example, at 35, the relay contacts 16, 17 are closed and the relay 33 proceeds to close. Before final closure, however, it bridges the contacts 34, energizing the winding 32 from the local source 19, 21 and withdrawing the latch 31 so that, when the rolling operation is concluded and the current is taken off the motor, the tripping circuit is closed and the circuit-breaker opens to enable the " earth " to be cleared.

Title: Improvements in or relating to the neutralization of acid solutions of caprolactam
IPC: C07D201/16
Filed: 1966-01-14
Abstract: A process for neutralizing solutions of e -caprolactam in sulphuric acid wherein the neutralization is effected with ammonia and the ammonium sulphate formed is subsequently recovered in the presence of water, comprises utilizing the heat evolved during the neutralization reaction to heat the neutralization mixture to a temperature of from 40 DEG  to 50 DEG  C., at a pressure of from 0.055 to 0.095 absolute atmospheres, so that substantial hydrolysis of the caprolactam is avoided and the caprolactam separates from the aqueous phase, and conditions are established in the mixture to evaporate therefrom a substantial portion of the water present in the mixture, thereby separating the crystallized ammonium sulphate substantially free from entrained caprolactam. The heat of neutralization may constitute the sole source of heat or a minor amount of external heating may additionally be supplied.  The process may be carried out in a continuous manner, the ammonium sulphate slurry being centrifuged, the ammonium sulphate crystals being washed with cold water to remove the caprolactam and the combined mother liquors and wash liquors being continuously recycled to the neutralization zone.  The process may be carried out in an apparatus comprising at least one crystallizer and a separator.  A means for applying a vacuum to the crystallizer may be incorporated.
