Patent GB-606976-A (GB)
Title: Prism spectrometers
IPC: G01J3/16
Filed: 1945-11-26
Abstract: 606,976. Speedometers. AMERICAN CYANAMID CO. Nov. 26, 1945, No. 31839. Convention date, March 21. [Class 97 (i)] The instrument includes an entrance slit, an off-axis parabolic collimating mirror, a Wernicke prism and an exit slit in optical alignment. As shown in Fig. 1, light after passing through an entrance slit 2 is reflected by mirror 3 on to an off-axis parabolic mirror 4 which collimates the beam and directs it to a Wernicke prism. This prism forms the subject-matter of Specification 607,033, and consists of two crown glass sections 5, 6 and a liquid section 7, the whole being surrounded by a jacket 8 through which flows water at a controlled temperature. The prism serves to disperse the rays of light which then fall on to a mirror 9 to be reflected by a parabolic mirror 10 and plane mirror 11 on to the exit slit 12. Mirror 9 is adjustable to bring rays of any one wavelength which emanate from prism 6 into focus at the slit 12. To reduce the instrument's size it may be rendered auto-collimating or the device may be duplicated by employing the exit slit of one as the entrance slit of the other to increase light efficiency. The liquid section 7 of the Wernicke prism is filled with a colourless liquid ester of an acid selected from the group consisting of orthomethoxy cinnamyl fatty acids, paramethoxy cynnamyl fatty acids and cynnamylidene fatty acids.

Filed: 1954-05-03
Abstract: 781,565. Comparing colours. GOSSEN & CO. GES., P. May 3, 1954, No. 31899/56. Divided out of 781,564. Class 97(1) [Also in Group XL(a)] A colour temperature indicator comprises an area covered with a daylight fluorescence colour and an area covered with an ordinary ncnfluorescence light-reflecting colour, the areas being arranged' side by side in a common plane so that the two areas appear to be of the same brightness when illurriinated by light of a determined colour temperature. To give an increased range of measurement the fluorescent strip 6, Fig. 1, is arranged in steps of brightness, or has a graded filter superposed thereon, the step which has the same brightness as the ordinary colour strip 7 giving the colour temperature of the illuminating light read off a scale 8. The invention is based on the fact that, for a continuous spectrum source, the amount of ultra-violet present depends on the colour temperature, this light also affecting the intensity of the coloured light emitted by fluorescence of the strip 6. To increase the sensitivity of a filter transparent only to part of the ultra-violet light may be placed before the strips. Suitable fluorescence colours are Rhodamine B extra, and Lumogen T orange GG whilst the ordinary light-reflecting colour may be molybdate red.

Title: Process and apparatus for drawing sheet glass
IPC: C03B15/08
Filed: 1959-09-22
Abstract: 908,148. Drawing sheet glass. PITTSBURGH PLATE GLASS CO. Sept. 22, 1959 [Nov. 3, 1958], No. 32201/59. Class 56. In the drawing of sheet glass from a molten bath through a drawing chamber wherein coolers are spaced for the sheet and the bath and disposed in a central area of the chamber and air flows upwardly along the sheet and a pattern of air flow is established due to the cooling, the pattern of air flow is disturbed by directing a separate fluid stream in the central area in an upward direction from a location adjacent to and not substantially above the coolers and the rate of flow of the fluid stream is controlled to permit some flow of air upward with the rising sheet. In a conventional sheet drawing apparatus in which a sheet 10 is drawn from molten glass 12 in a drawing chamber 22 by rolls 18 in a chamber 20, the chamber 22 is substantially enclosed, with the sheet 10 passing up between catch pans 30 and L-blocks 24 lying adjacent the molten glass 12. Conventional water-coolers 32 are provided on either side of sheet 10. As shown in Fig. 2, burners 34 are provided adjacent L-blocks 24 to give an oblique upward flow of gas on either side. In addition to the burners, the air flow is controlled by plates 36 between the upper edges of the coolers 32 and the glass sheet 10 and by dampers 38 at the entrance to the chamber 20. As shown in Fig. 6, burners 3411 are positioned above and outside the coolers 32 to give an upward stream of gas, the air flow also being controlled by dampers 38. In both Figures, the subsequent main air flow is shown in heavy lines, intermediate velocity by light solid lines and relatively low velocity air currents by broken lines. In modifications, not shown, burners 34 and dampers 38, as in Fig. 2, only are used, burners between the coolers 32 and sheet 10 and directed obliquely towards the coolers and dampers 38; burners 34, burners with attached baffle plates between the coolers 32 and sheet 10 and dampers 38; burners between the coolers 32 and sheet 10, plates 36 and dampers 38: in each case the air currents adjacent the sheet 10 are low velocity upward currents. Each burner 34, 3411 comprises a pipe with closely spaced holes which extends across the full width of the chamber 22 and is mounted so that the inclination of the flames can be varied. The plates 36 may be mounted, as shown in Fig. 8, by means of brackets 44 which fit over the tops of coolers 32. The plates are pivoted to the brackets 44 and may be varied angularly with respect to the sheet 10 by a rod 42 extending through the end wall of chamber 22. The dampers 38, 38<SP>1</SP> may be similarly pivotally mounted by brackets fitting over the edges of the catch pans 30. Specification 659,256 is referred to.

Abstract: 1,056,107. Electromagnetic relays. WESTERN ELECTRIC CO Inc. Aug. 15, 1963 [Aug. 31, 1962], No. 32269/63. Heading H2B. [Also in Divisions H1 and H4] A ferreed switch comprises one or more dry reed contact sets surrounded by a thin sleeve of square loop magnetic material. A magnetic shunt plate 804 positioned at the mid-point of the sleeve separates the sleeve magnetically into two independent halves. When the two halves are magnetized series-aiding, the flux return path is through the reeds, causing them to close. When the two halves are magnetized in series opposition, the flux through the reeds is a minimum, causing the reeds to open. Each end of the sleeve has two windings, one winding having a larger number of turns than the other. The winding with the largest number of turns is connected in series opposition with the winding having the fewer number of turns on the other end of the sleeve. When either of the sets of windings thus formed is energized, the two ends of the sleeve are poled oppositely and the contacts are opened. When the two sets of windings are energized simultaneously with equal currents, the two sleeve ends are poled series-aiding and the contacts are closed.
