Title: Changing the transparency of the bounding surfaces of solid di-electrics by interference layers
IPC: H01Q17/00
Filed: 1951-05-31
Abstract: 711,357. Modifying surface reflection. OPTISCHE WERKE C. A. STEINHEIL SOHNE GES. May 31, 1951 [Oct. 1, 1948], No. 12980/51. Drawings to Specification. Class 97(1) A system of three or more interference layers for changing the spectral transparency of the boundary surfaces of an optical component is characterized by the fact that the parameters Di=4# ni di (where ni and di are the refractive index and thickness of the i th. layer) satisfy within Œ 10 per cent a system of equations (1) defined in the Specification connecting the reflection co-efficients of the layers and functions # (Di) which are also defined in the Specification; the ratio Di+1/Di is not equal to α/# where α and # are whole numbers less than 5. The Specification contains a mathematical discussion on the derivation of the system of equations and of the functions # (Di) and describes how to use the equations to determine the thicknesses and indices of the various layers which are necessary to produce an interference filter having a spectral curve approximating that desired. One example is directed to the formation of interference lavers ensuring substantial freedom from reflection in the visible spectrum. A graph of # (D), as defined by equation (10) in the Specification, is first plotted. A number of equations (1) equal to the number of layers (six in the example) which it is desired to use is set up. It is then decided that the layers shall be alternately of materials of certain refraction indices so that the reflection co-efficients of the layers can be determined. By a process of approximation and the use of graphs, the values Di of the layers are then determined using the six equations (1). The spectral reflectivity of a system of six layers produced in this manner is shown in Fig. 2. In the second example, it is desired merely to reduce reflection from a glass surface. It is assumed that four #/4 layers are to be used and it is laid down that the refractive index of the outer layer is not to be less than 1.45. From equation (4), defined in the Specification, the reflection coefficients are determined; hence the refractive indices are found. It is found that there is no suitable material having one of the refractive indices determined, and so a material having a refractive index approximately equal to that one is used. Knowing the refractive indices, the values D i  are now ascertained in the same way as for the first example.

Abstract: 560,932. Electric furnaces. GARDNER, D. Sept. 21, 1942, No. 13293. Convention date, April 4, 1942. [Class 39 (iii)] A furnace suitable for the production and distillation of metallic magnesium is heated externally by the passage of current through a body of loose granular material, the resistance of which is varied by means of pressure platens acting upon it. A reaction chamber C is surrounded by a perforated wall 22, which is surrounded by an uptake flue F from which gases pass to conduits P, Fig. 3, in the wall of the chamber 24 and thence to a condensing chamber within the body of the block V. Hydrogen or other gas may be introduced through passage 26. The tube 21 may be centred in the chamber 24 by radial ribs. Two diametrically opposite conduits P may discharge into two compartments of the condenser which may be used alternately. The condenser is partly within and partly without the heating chamber to prevent condensation of the metal vapour in the upper part and allow it in the lower part. Vents in the upper part of the condenser compartments may discharge into passages 56 in the wall of the chamber 24, Fig. 3, and thence through the upper block 28. The material to be treated is fed downward by a screw 60, the pitch of which may increase downward. The screw may be rotated uniformly or intermittently by worm gearing 66 through a spring 65. The cross shaft 68 is connected by gearing 69, shaft 70, and gearing 71, to a power shaft 73. The lower end of the feed screw may be connected to the driving shaft 70 by gearing 77, 74. Solids are discharged from the furnace on to a rotary table 82. The electric heater comprises granular resistance material 84 arranged in annular layers of increasing fineness outwards, so that the outer fine layer is a heat insulator. The material is enclosed by fixed plates 89 backed by brickwork, and by movable platens 93 which are adjustable to vary the pressure on the material 84 and so vary its resistance. All the platens are geared together by chains 98 and cross shafts 101 with helical gearing 102, so that pressure may be applied uniformly by rotating a handwheel 104. Current is applied to opposite pairs of platens, Fig. 3. The layers of the material 84 may be separated by impregnated paper sheets which survive sufficiently to keep the strata intact. Adjustment of the platens 93 may be automatic, controlled by the electrical or temperature conditions. The screw 60 may alternatively be stationary and the heating chamber and heater rotated. Specification 502,576 is referred to. '

Abstract: 1452874 Vehicle battery temperature control systems DAIMLER-BENZ AG 2 April 1975 [6 April 1974] 13474/75 Heading H1B [Also in Division B7] A motor vehicle comprises an internal combustion engine, a storage battery 16 enclosed in a protective housing 18 and an air pump 11 for supplying air to exhaust gas treatment devices 4, the air pump being arranged to provide a flow of air through the gap 17 between the battery and the protective housing. The pump 11 supplies air via pipes 9 to the devices 4, the heat generated by which would cause excessive heating of the battery. To counteract this effect the battery is cooled by air sucked into the housing through a shielded inlet pipe 19 and delivered to the pump by a pipe 21. When the battery temperature is low, a heat sensor 26 opens a valve 25 to allow the pump to draw in air from the engine compartment instead of via the inlet pipe 19. To obtain rapid warning of a cold battery the air inlet to the housing 18 may communicate with the engine compartment or hot sections of the exhaust pipe.
