Title: Improvements in or relating to the winding of electrical apparatus, for example, electric transformers
IPC: H01F27/34
Filed: 1944-10-06
Abstract: 580,585. Transformers. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Oct. 6, 1944, No. 19236. Convention date, Oct. 7, 1943. [Class 38 (ii)] A transformer has a continuous high voltage winding arranged as a stack of coaxial sections each comprising a number of disc-shaped coil layers, the winding being continuous through sets of turns in sequence, each set consisting of those turns of one section which are in different layers but have the same diameter, the first connections to all sets being made to turns in the same layer. Fig. 7 shows parts of a core 31 and of a low-tension winding 32 round which are two sections of the high-tension winding, each comprising two layers 51, 52 and 53, 54. Terminal connection 55 is connected to coil 12 of Sec. No. 1, and connections between turns of this section are made in the inverse numbering order to turn 1 as shown in Fig. 9, and then by connection 56 to turn 1 of Sec. No. 2, the internal connections of which are made to turns' in numerical order to turn 12 which is connected by lead 57 to the next section. Fig. 5 shows the actual arrangement of turns 1 and 2 and how, owing to the crossover connections, each turn subtends rather less than 360 degrees. The layers of each section are separated by twelve equidistant radial spacers between which pass the cross-connectors, and the sections are separated by similar thicker spacers. This winding arrangement results in the maximum potential between' adjacent conductors being the voltage between two turns, thus lessening the insulation thickness. The effect of connecting the turns as described is to increase the interturn capacity and thereby give a better voltage distribution across the winding under surge conditions.

Patent GB-1041636-A (GB)
Title: Treatment of stainless ferritic sheet and strip material
IPC: C21D8/04
Filed: 1963-05-15
Abstract: A process for the treatment of stainless ferritic sheet or strip material containing 14-20% by weight of chromium, comprises cold rolling and annealing the cold rolled material at a sufficient temperature and for a sufficient time as to ensure the formation of small amounts of transformation structure within the ferrite material. During annealing at a suitable temperature, usually in the range 850 DEG -930 DEG C., small portions of austenite are formed within the material, which form transformation structures on cooling, the presence of which has a similar effect on the yield point elongation of the material as does a small degree of cold re-rolling and so dispenses with the latter treatment.  In an example given the time of annealing is 1 1/2 minutes.

Patent GB-994394-A (GB)
Title: Process for melting ferrous metal
IPC: C21C5/56
Filed: 1963-05-15
Abstract: A process for melting ferrous scrap wherein the heat required for the melting is primarily derived from the combustion of a material based on the element silicon in an oxidizable state, and gaseous oxygen in determined proportions. The element silicon may be introduced into the furnace in a pure state, as a silicon alloy, such as ferro-silicon or as a compound such as calcium silicide.  In the form described an initial pool of molten metal is formed in an open topped vessel, into which is introduced an oxygen lance.  The rate of supply of oxygen, and the rate of addition of scrap metal and silicon into the vessel precisely determine the rate of melting and the temperature of the molten metal forming the pool.  A slag making material such as burnt lime or limestone is also added in such proportion as to produce a slag of the desired lime:silica ratio. Further additions may be made if necessary of materials to alter the properties of the slag formed during the reaction, e.g. the surface tension, fluidity, basicity &c.  After removal from the vessel, the molten metal may be superheated by passage of further oxygen therethrough. Specification 576,133 is referred to.
Patent GB-1585148-A (GB)
Title: Radio determination of position using satellites
IPC: G01S11/08
Filed: 1978-05-12
Abstract: The time-of-arrival of timing signals transmitted by two satellites is measured relative to a crystal clock, and an approximate position fix is computed for the ship or other object being located. Because of clock error the position fixes are displaced along a hyperbolic line of position. A two-way active range measurement through a third satellite or one timing signal satellite enables computation of an independently determined line of position, the true position fix being at its intersection with the hyperbolic line of position. The clock error is corrected and the method of position fixing from two timing satellites is repeated until the clock drift exceeds acceptable limits. A continuous navigation service and also position surveillance are realized.

Abstract: 274,912. Ansaldo Soc. Anon., and Soc. Anon. Officine Galileo, (Assignees of Traversi, R. A.). July 24, 1926, [Convention date]. Sights and methods of sighting.-A panorama sighting telescope, particularly applicable to ordnance, comprises an upper reflecting prism b adjustable in azimuth from a fixed point h and a compound reflecting prism a mounted in front of the prism band independently adjustable about a horizontal axis from a second fixed point e for elevating the line of sight. In the form shown in Fig 1, the elevation prism a and direction prism b are mounted on a sleeve d rotatable in azimuth by a gear h, the elevating prism a being rocked independently of prism b by a gear e of the rack and pinion type, which causes vertical movement of a sleeve f connected with the prism a by an extension g. The erecting prism i mounted on a sleeve p is rotated through half the angle described by the. prism b by means of planetary pinions j. The Specification as open to inspection under Sect. (91) (3) (a) also describes with reference to Fig. 1 (cancelled) (1) means for connecting the telescopes A<1> with gun elevating and sightcorrecting gears, (2) a range dial with separate means for adjusting the index to compensate for changes in muzzle-velocity, and (3) a fuze-setting device. The gun trunnion carries worm sectors A meshing with screws B on racks D which through wheels E and pinions F elevate the sights. The initial angle of sight, set up by a hand-wheel G which sets an index L to a range dial J, causes through wheels 0, P, and differential gear R, V, rotation of shaft C, screw B, and gear F. The future angle of sight is set up by hand-wheel H which rotates the dial U and the shaft C through the differential gear. Deflection is set up on a dial 19 by operating a hand-wheel 18 and shafts 30, 22, 21, 23. Corrections in elevation for " roll of ship " are introduced by moving the index L by means of a pendulum Z acting through a differential gear X on a wheel 6 connected with shaft 28 by a differential gear Y. The planetary pinion 7 of the gear Y is connected with the gun-elevating gear by links 10 - - 12. The corrections for muzzle-velocity are effected by interchangeable cams within the range dial K acting through a spring-controlled rack to apply correcting movements to a radial pointer (not shown). The fuze-setting gear 31 is operated by a handwheel 29 in accordance with curves on a dial 26, the index 27 of which receives the correcting movements imparted to the elevation index L on the other side of the gun. This subject-matter does not appear in the Specification as accepted.
