Title: Improvements in or relating to transformers for use in high-frequency heating generators
IPC: H01F27/32
Filed: 1954-01-19
Abstract: 751,021. Transformers. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 19, 1954 [Jan. 22, 1953], No. 1596/54. Class 38 (2). A transformer supplying a high-frequency heating coil comprises a helical water-cooled tubular primary coil 1 which surrounds a substantially cylindrical ferrite core 11 and is enclosed in an oil-filled tank 3 made of insulating material, and encircled by a secondary coupling coil 5 in the form of a bent metal strip. The core 11 is supported by three insulating strips 13 which enter slots in the core and consist of two parts having adjacent recesses between which the coil 1 is gripped. The tank 3 is of glass or quartz with a base 27 and a flange 7 cemented to it. To this flange is fixed a cover 8 through which pass ends 9, 10 of coil 8 in an oiltight manner, these ends being connected to an h.f. generator, and to a supply of cooling water. End 10 passes through an axial hole in the core which is interrupted by a saw cut 29 to reduce the self inductance of the lead. The secondary coil 5 which, by being external to the casing, can be movable or easily replaceable, bears terminals 23, 25 at its out-turned ends 19, 21 for connection to the heating coil, and has soldered to it a tube 17 which carries cooling water, which may, if desired, be that which passes through coil 1. The heat generated by core losses is carried by the oil to the water-cooled coil 1. Specification 751,022 is referred to.

Abstract: 821,466. Navigational instruments. PIERCE, M. R., and ZUCKERMAN, T. E. Jan. 16, 1957 [Jan. 17, 1956], No. 1689/57. Class 97(2)  An optical navigational device comprises means for providing a representation of a point, representing an assumed position, as on a universal plotting sheet, and superposed thereon, an optical image of an observed celestial body displaced from said point in a direction corresponding to the azimuth direction of said body from the navigational device and by an amount representing the difference between computed and observed altitudes of the body. In the form shown, Fig. 12, light from a star is received through a double Dove prism 23, 24, which is rotated, by coarse and fine adjustment means, not shown, to the estimated altitude of the star about a horizontal axis in the common hypotenuse face. A telephoto lens 30, 30<SP>1</SP> images the star, after reflection of the light beam by a mirror 31, in a focal plane 32 if a pivoted mirror 33 is removed from the light path. Superposed on the image of the star, by means of a partially reflecting mirror 101, is the image, produced by a lens 44, of an illuminated graticle 41 which carries an azimuth circle 5<SP>1</SP>, a longitude line 7<SP>1</SP> and latitude lines 8<SP>1</SP>, 9<SP>1</SP> and 10<SP>1</SP> spaced at one degree intervals which are imaged respectively at 5<SP>11</SP>, 7<SP>11</SP>, 8<SP>11</SP>, 9<SP>11</SP> and 10<SP>11</SP>, Fig. 2, the intersection 6<SP>1</SP>, imaged at 6<SP>11</SP>, representing the estimated position of the star. Two wires 3<SP>1</SP>, 4<SP>1</SP>, which are actually adjacent the graticule 41, are imaged at 3<SP>11</SP>, 4<SP>11</SP> to form meridians and are at a spacing adjustable to correspond to the latitude. For this purpose they are carried by members 47, 48 slidable on guides 53, 54 and are actuated by a rotatable knob, not shown, graduated in terms of latitude and carrying projections engaging slot 61, 62 in the respective members. A fixed wire 2<SP>1</SP> is imaged at 2<SP>11</SP> to form an azimuth line. The wires are all fluorescent and are illuminated by an ultra-violet source 51. Also imaged in the focal plane, using a half-silvered mirror 100, is a line 1<SP>1</SP> on a plate 77 adjustable by a screw 85. The image 1<SP>11</SP> is moved by adjusting the screw, to align it with the observed star position 13<SP>11</SP> and so becomes a line of position. A bubble 88 may be imaged at 88<SP>11</SP> for correction purposes. The composite image may be viewed, with the mirror 33 in the position shown, through an erecting prism 92 and eyepiece 91. When the mirror is lifted, as by a reflex camera mechanism, the image may be photographed in the plane 32 using a focal plane shutter. U.S.A. Specification 1,653,585 is referred to.

A photographic type-composing machine comprises a continuously moving matrix, and a light-sensitive surface receiving images projected by an optical system in response to illumination of the matrix by light flashes timed to project images of selected characters carried on the matrix on to the surface at the required locations, wherein there is a plurality of independent light projectors and associated light-deflecting means and the control circuits cause projection of the characters in a sequence which is independent of the sequence of characters in the text being composed. Fig. 1 illustrates apparatus in which characters are carried on a moving matrix 2; there are two projection units or flash tubes 8, 18 associated with mirrors 12, 22 of galvanometers 13, 23. In the " start " position, projection unit 18 directs light along path 20 and 24 to form a light patch 26 on the matrix, illuminating the selected character, the image of which flashes along path 25 to the light-sensitive surface. The mirror 22 then moves through a small angle, so that the next " flash " of unit 18 will project the selected character on to a different area of the light-sensitive surface, e.g. to form the next letter in the line of type. Simultaneously at the " start " position, projection unit 8 illuminates the matrix 2 at a different area 27, e.g. to print the last letter of the line. An alternative arrangement (Fig. 4, not shown) involves three flash tubes (72), (74), (76) with associated galvanometer mirrors (78), (80), (82) so that the projection unit which is first conditioned by the control circuits to project a character will project first regardless of the position of the character in the composed line. The circuits controlling character selection and the timing of the projection are similar to those disclosed in Specification 1,093,856.
