Title: Light responsive electrical lamp dimming means
IPC: H05B39/08
Filed: 1969-07-04
Abstract: 1,270,881. Photo-electric control of lamps. MINNESOTA MINING & MFG. CO. July 4, 1969 [July 5, 1968], No.33937/69. Heading G1A. The intensity of a source of light is varied between fixed maximum and minimum intensities as a direct function of the background intensity. Preferably the source of light is the aspect lights of a traffic signal and the intensity is varied by chopping the A.C. supply to the particular lamp using the circuit shown in Fig. 5. Background illumination is sensed by the device shown in Fig. 9, mounted in the rear wall of the traffic signal, having a photo-cell 272 illuminated through a yellow plug member 278 which has a screwdriver slot 286 which acts as a light filter. The hollow centre of plug 278 is provided with an apertured disc 292 which controls the amount of illumination received. These parts are represented in Fig. 5 as follows; photocell 182, yellow filter 200 and apertured disc 202. In operation, reduction of the light falling on photo-resistor 182 will increase its resistance causing the R. C. integrating circuit formed of resistor 190, photo-cell 182, variable resistor 194, capacitor 192 to bias diode 184 to trigger the bidirectional thyristor 186 into conduction for less than a full cycle of the supply thereby reducing the brightness of aspect lamp 92<SP>1</SP>. The colour of the filter and the size of the aperture may be varied to provide the required range of intensity. The size of resistor 194 determines the minimum intensity of the light source. In a modified circuit used when only one aspect of the traffic signal is to be dimmed additional capacitors and resistors are used, Fig. 7 (not shown).

IPC: C07C51/265
Filed: 1957-11-01
Abstract: Cyclic carboxylic acids are prepared by oxidising an alkyl or haloalkyl substituted compound of aromatic character or a closely related oxygenated derivative thereof, i.e. where the substituent is an aldehyde, hydroxy- or alkoxymethyl, acyl or hydroperoxy group, or one of the alkyl substituted or oxygenated compounds containing a polar substituent inert to oxidation under the reaction conditions, the reaction being carried out in the liquid phase by means of molecular oxygen or ozone in the presence as catalyst of a compound of a metal of variable valence and of hydrogen chloride and in the absence of bromine and bromine-containing compounds.  The hydrogen chloride is preferably carried in the oxygen-containing gas in a concentration of from 0,001 to 1 gm. mole per 100 litres of oxygen at N.T.P. and the total amount of chlorine introduced is preferably 0,1 to 10 gm. atoms per mole of starting material.  The process is said to be applicable to aromatic and heterocyclic compounds containing up to three substituents convertable to carboxyl groups and which may also contain as inert substituents halogen, nitro, sulphonamide, alkoxy, aryloxy, acylamino, acyloxy, carboxy, sulphonic acid or ester, amido, amino or benzoyl groups.  In examples p-toluic acid is oxidised to terephthalic acid in benzoic acid or phthalic anhydride and in the presence of cobalt and manganese acetate.  The Provisional Specification refers to the process where the hydrogen chloride is obtained from a metal chloride or an organic chloride which yields hydrogen chloride under the reaction conditions and two further examples describe the oxidation of p-toluic acid (1) in the presence of lithium chloride together with a catalyst and (2) in the presence of cobalt and manganese chlorides as catalyst.  Specifications 840,009 and 842,998 are referred to.

Title: Improvements in or relating to apparatus for making hollow glass bodies by pressing and blowing
IPC: C03B9/193
Filed: 1928-11-29
Abstract: 302,153. Naamlooze Vennootschap Maatschappij tot Exploitatie van Uitvindingen. Dec. 10, 1927, [Convention date]. Blowing ; pressing. - Relates to a machine for making hollow glassware, particularly electric lamp bulbs, in which parisons are formed by pressing and are afterwards blown to shape. The invention consists in making the glasscontacting parts of the parison mould and the plunger of heat-insulating material, and lacing this material with metal of high conductivity. The high conductivity of the metal ensures that its surface temperature is uniform, so that marks on the finished ware, due to uneven chilling of the glass, are avoided. The heat transmission of the parts as a whole is sufficiently low, however, to prevent too much heat from being abstracted from the glass, but not so low as to permit the metal to stick to the glass. In the construction shown, the plunger 10 and parison mould 11 consist of blocks 14, 15, respectively, of heat-insulating material such as asbestos, cement. or soapstone, with a coating or facing 12 of sheet silver clamped between parts 20, 21 which screw on to one another. The blocks 14, 15 are cooled, if necessary, by liquid circulated through chambers 18 by pipes 16, 17.

Abstract: 430,421. Aircraft lamps. HARLEY, M. C., The Red House, Cranford, Middlesex. Dec. 14, 1933, No. 35258. [Class 4] [See also Group XI] Aircraft illuminating-apparatus comprises a projecting lamp of the kind having means productive of a light beam comprising a portion which is substantially parallel or non-divergent and a portion laterally dispersed and deflected generally downwards in relation to the lamp axis, the lamp being mounted on an external aircraft surface so that the lamp axis may be angularly adjusted in a substantially vertical plane extending forward in the general line of flight. As shown, a lamp of the type described in Specification 372,285, [Group XI], has the upper portion of the deflected beam deflected in the direction of the lamp axis by means of a plano-cylindrical astigmatic lens d and diffused by a ribbed glass plate e adjacent or cemented to the lens. The lamp is retractable into and out of, e.g. the aircraft wing, and is hinged at f to the wing surfaces. Movement of the lamp is effected by Bowden wires j, j<1> adjustable from a sprocket wheel o, the position of which may be held by adjustable friction means. The wires pass over guide pulleys l, l<1> and are secured one to each end of a quadrant g mounted on a bracket h on the back of the lamp. The quadrant may be housed in a fairing. The hinge axis f may be set somewhat oblique to a transverse axis of the aircraft and a shield w may be provided. In a modification, the lamp is housed in a recess in a nose fairing and hinged forwardly under the control of a Bowden wire secured by a link to the lamp. The desired orientation of the lamp in its retracted position is obtained by means of a tapered packing ring interposed between the lamp and the rim carrying the front glass. The lamp is provided with an emergency light filament b situated above and behind the main filament b. In the case of an 8" lamp the filament may be displaced <3>/16" above and behind the main filament. Specification 326,162, [Class 75 (iii)], also is referred to.

(NH 4 ) 2 CO 3  and/or NH 4 HCO 3  and contacting the mixture with sufficient sulphide to precipitate the metal ions; (3) allowing the organic and aqueous phases to separate, (the aqueous phase now containing ammonium uranyl carbonate on solution plus precipitated sulphides); and (4) separating the precipitate from the aqueous solution. The uranium may be recovered as UO 2  or U 3 O 8  by increasing the concentration of (NH 4 ) 2 CO 3  or NH 4 HCO 3  to 1À2-2À5 mole/l. and calcining the resulting precipitate of ammonium uranyl carbonate. The process may form the second cycle of a process in which, in a first cycle, acidic Fe<SP>+3</SP> containing UO 2 <SP>+2</SP> solution is concentrated by extracting with UO 2 <SP>+2</SP> complexing agent, stripping the organic phase with Fe<SP>+2</SP> containing acid to produce an aqueous phase containing Fe<SP>+3</SP> and U<SP>+4</SP>, which is then reozidized to UO 2 <SP>+2</SP>. The organic extractant, in both cycles, may be di-2-ethyl-hexylphosphoric acid, together with tri-n-octylphosphine oxide as synergistic agent, in kerosene. If the starting liquor is acid, the organic phase from (1) may be scrubbed with H 2 O before proceeding with step (2).
