[Class 38 (ii)] In an automatic control system for regulating any physical condition such as pressure, temperature, humidity, a measuring instrument responsive thereto controls a bolometric device which influences the grid circuit of a gas or vapour filled discharge tube to effect continuous variation of the anode current whereby the physical condition is varied. In the apparatus shown, the temperature responsive resistances 3, 4 of a Wheatstone bridge 3, 4, 5, 6 are cooled differentially by air blown on to them by nozzles 14, 15 through slots 7, 8 in a plate 9, the slots being more or less shielded by a plate 2 which is moved in either direction, so as to uncover one of the slots, by a pointer 1 operated by a measuring instrument in accordance with variation of the quantity to be regulated. A transformer 24 supplies A.C. to the bridge and out of balance effects due to the cooling of either resistance 3, 4 are communicated through transformer 25 to the control grids 17<a>, 18<a> of gas or vapour filled discharge tubes, in circuit with a regulating coil 16. The protecting grids 17b, 18b may be energized through a transformer 21 from a phase shifting device consisting of a condenser 22 and a resistance 23. Specification 436,651 is referred to.

Abstract: 1336683 Modulating light RCA CORPORATION 19 April 1971 [9 March 1970] 23184/71 Heading H4F [Also in Divisions G2 and H1] An optical system for projecting an image on to a viewing screen 18 (Fig. 3) by means of a projection device, e.g. lens 17a, from an object 23a not parallel to the screen comprises a prism 32 arranged so that light reaches lens 17a as though originating from a plane 23b parallel to the screen, by positioning the prism so that a plane parallel to the plane 23b passing through the line of intersection of the entry and exit faces (produced if necessary) passes within the prism and is closer to the entrance face than the exit face. Object 23a may be a Schlieren optical system illuminated by lamp 15 and condenser 16a. The Schlieren system is formed by a cathode ray tube having a target electrode as shown in Fig. 2. 21 is the face of the C.R.T., carrying within the tube a plurality of electrically connected support conductors 22, which support an electrostatically deformable metal film 23, e.g. of Ni, Cu or Al.

Light reflected from the film forms the image to be projected, and stop 19 (Fig. 3) is placed at the focus of the projection lens 17a. Prism 32 may be a composite structure of two or more prisms to allow use of light which is not monochromatic (Figs. 4, 5 and 6, not shown).

Abstract: 277,342. I. G. Farbenindustrie Akt.- Ges. Sept. 10, 1926, [Convention date]. Addition to 268,830. Samples furnished. Benzanthrone derivatives. - Benzanthrones substituted in one or more Bz-positions are prepared by condensing such reduction products of anthraquinone and its derivatives as contain oxygen in the meso-position with maleic acid, ester, or anhydride, or with fumaric acid or ester. When the condensation is effected by simple heating together of the reacting bodies, intermediate products are produced which are converted into benzanthrone derivatives by further treatment with acid condensing agents. Thus from anthrone. and maleic anhydride is obtained a product of the probable constitution. By treating this product with an acid condensing agent, or by using such agent in the first place, there appears to be formed, according to conditions, either a dihydrobenzanthrone derivative such as or, bv oxidation and loss of carbon dioxide. Bz-1- oxybenzanthrone. According to examples, the following products are obtained :-(1) a condensation product (formula I) by heating anthrone with maleic anhydride; it yields Bz1-oxybenzanthrone by heating with aluminium chloride and nitrobenzene; (2) a dihydro-Bz1-oxybenzanthrone by heating anthranol with maleic acid and sodium-aluminium chloride and pouring on to ice; on drying it oxidizes to Bz1-oxybenzanthrone; (3) a Bz1-oxybenzanthronesulphonic acid by heating anthrone with diethyl fumarate and sulphuric acid, pouring into water, and salting out.
