Abstract: 480,370. Screw-and-nut gearing. WILMOT-BREEDEN, Ltd., and SPICER, H. J. Sept. 11, 1936, No. 24789. [Class 80(iii)] [Also in Group X] Operating mechanism for pivoted windows comprises a rotary member h having oppositely directed external and internal screw threads which engage respectively with members a and i connected to the fixed and hinged frames, the member h being rotated by a device which has a slidable connection therewith and which is secured against axial movement in the member a. In the construction shown, the member a is swivelly connected by means of a stud c to a support b which is secured to the window frame. The means for rotating the member h consists of a handle p mounted on spindle m of square or other non-circular crosssection. The spindle slidably engages with a correspondingly shaped aperture in the rear wall of the member h, and is prevented from axial movement by the engagement of its handle p and a collar p with opposite faces of a flange o on the member a. The outer end of the inner member i is bifurcated and carries a pin which serves as a pivot for a link k connected to the hinged frame.

Title: Improvements relating to ceramic-to-metal seals
Inventor: WHITMORE EDWARD JOHN
IPC: C04B37/02
Filed: 1953-09-09
Abstract: 746,963. Ceramic-metal seals electroplating. FERRANTI, Ltd. Sept. 2, 1954 [Sept. 9, 1953], No. 24897/53. Classes 36 and 41. [Also in Group XXII] A ceramic-metal seal is made by applying to the ceramic surface a film comprising a suspension of finely divided metallic carbide, firing the film in an atmosphere containing hydrogen to cause the carbide to form on the surface a strongly adherent layer which is partly or wholly converted to metal by said atmosphere, forming a metallized surface thereon which will be wetted by a brazing material, and brazing a metal member to the metallized surface. The carbide material may be tungsten carbide or a mixture such as tungsten and titanium carbides. The adherent layer may be metallized by plating with a metal which will bond thereto, such as nickel, cobalt or iron, and then with a metal to assist brazing, such as silver which is subsequently melted by firing in a non-oxidizing atmosphere. For example, the adherent layer may be nickel plated for 20 minutes at a current density of 0.07 amp./sq. inch., and then silver plated for 20 minutes at the same current density and fired in hydrogen at 1050‹ C. Alternatively the adherent layer may be coated with a film of like carbide material mixed with a less amount of finely divided metal which will bond to the adherent layer and be wetted by a brazing material, this film being fired in a non-oxidizing atmosphere. In a further modification the metallized surface may be formed by the application of a suspension of a metal powder and then sintering in a non-oxidizing atmosphere. The metal member may be of nickeliron and may be nickel-plated and silverplated and then fired in hydrogen before being brazed to the metallized ceramic surface, silver being used as the brazing medium.

Title: Method for the manufacture of hydrocyanic acid from volatile nitrogen compounds and hydrocarbons
IPC: C01C3/02
Filed: 1951-10-29
Abstract: Hydrocyanic acid and hydrogen are produced from volatile nitrogen compounds and hydrocarbons by passing a mixture thereof containing at least a half a nitrogen atom per atom of carbon with oxygen in such quantities if at all, as to ensure the reaction remains endothermic, through or around continuously heated metal tubes or elongated chambers made of or coated with catalysts, the reaction taking place on the catalytic surfaces at above 800 DEG  C., preferably at 900-1200 DEG  C.  Catalysts may be metals or alloys of Pt, Ru, Os, Pd, Rh, Ir, Cu, Au, Re, Ta, Nb, V, Mo, or W, as well as one or more oxides of the second or third groups of the Periodic Table, such as Al, Sc, Y, La, Be, Mg.  These may be in the form of foils or gauzes, which may in addition to lining the tube walls, project into the tube, or as coatings, or the tubes may be provided with ceramic layers or inserts which may themselves be catalytic or suitably impregnated.  The gas mixture may be passed through the tubes at a linear speed of more than 5 metres per second.  The preferred apparatus consists of a bundle of tubes, vertically or horizontally arranged in a heating furnace, the tubes having individual flexible connections and lead-in pipes of smaller diameter which enable the gas to be fed to and withdrawn from the hottest parts of the tubes. Cooling devices may be arranged externally of the heating chamber. The tubes may be heated electrically, by irradiation or by heating gases.  According to an example, ammonia and methane in a volumetric ratio of about 1 : 1 were passed through an externally heated heat resistant steel tube lined with a platinum foil containing 10 per cent ruthenium.  The rate of flow employed at reaction temperatures between 950 DEG  and 1150 DEG  C. was from 6 to 60 kilograms of ammonia per day using a 10 mm. diameter tube or 30 to 240 kilograms per day for a 60 mm. diameter tube.  Industrial gas mixtures may be used containing as well as ammonia and methane, hydrogen or nitrogen contaminants.

Abstract: 1,119,253. Light modulators. WESTING- HOUSE ELECTRIC CORP. 8 June, 1966 [29 June, 1965], No. 25453/66. Heading H4F. A display screen comprises a cholesteric phase liquid crystal film which exhibits a change in its optical scattering properties, i.e. reflecting properties, in response to temperature changes. A thermal image is impressed on the heatsensitive cholesteric layer by means of an array of magnetic transfluxors having two apertures through which electrical conductors pass. Two electrical conductors pass current through one aperture for writing information into the transfluxor core and erasing information from the transfluxor core respectively, and one electrical conductor passes alternating current through the other aperture for providing magnetic flux reversals in the transfluxor core to generate heat in accordance with the amount of information written therein. The amount of heat dissipated also depends on the frequency of the alternating (excitation) current. White light incident on the liquid crystal film is selectively scattered in accordance with the temperature of the film and a coloured image is displayed. The liquid crystal film may be held at a suitable temperature to give an overall background colour such as black or red in reflected white light, the coloured image being superimposed. By using monochromatic viewing light brightness along will vary with temperature.
