Title: Photographic Products and Processes
IPC: G03C8/52
Filed: 1967-01-11
Abstract: 1,182,308. Photographic materials and processes. INTERNATIONAL POLAROID CORP. Jan.11, 1967 [Jan.11, 1966], No.38566/69. Divided out of 1, 182, 302. Heading G2C. A photographic material for use in the diffusion transfer process comprises a support coated with a silver halide emulsion layer and optionally a translucent second layer, either or both layers containing an opaque substance in an amount which does not stop exposure of the emulsion through the second layer and a siliceous material in the layer or layers containing the opaque substance. The material preferably contains a top layer with a silver precipitating agent but such a layer may be formed during development if the developer contains such an agent and a polymer. In imagewise exposure and development of the material in the presence of a silver halide solvent, the negative image formed in the emulsion layer is masked by the opaque substance so that only the positive image is seen. In the examples, a paper support is coated with a layer containing a gelatine silver halide emulsion titanium dioxide, silica and alphamethyl glucoside as humectant (see Specification 1,182, 307). The material is imagewise exposed and developed with an alkaline solution containing a developer, a silver halide solvent, development nuclei (sodium sulphide and lead and cadmium acetate) and sodium carboxymethoxycellulose so that a positive silver image is formed in the carboxymethylcellulose layer deposited. The addition of silica gives a denser silver image. Alternatively, the silver halide layer may be coated with an image-receptive layer of lead sulphide in gelatine. Other opaque substances such as calcium carbonate, magnesium oxide or barium sulphate may be used or the substance may be produced in the material after imagewise exposure. Magnesium aluminium silicate is also specified as a siliceous material.

Patent GB-861238-A (GB)
Title: Process for making steel
IPC: C21C5/32
Filed: 1958-12-03
Abstract: Steel is made in a converter by a first stage of blowing through the bottom tuyeres to a carbon content of 0.7 to 1.5% and top blowing in a second stage with lime loaded oxygen with the converter turned down.  Lime may be added during the first stage in the form of lumps, powder or briquettes, or it may be supplied as a powder suspended in the bottom blown gas which may be air enriched to 30% oxygen.  With low silicon irons, the slags from the previous operation may be suitable for the first stage without further addition of lime. During the second stage, ores, oxides of iron, or siliceous materials may be added in bulk or in the form of powder blown in with the gas, and in the latter part of the second stage the oxygen may be free from suspended additions.  At the end of the second stage the refining may be terminated leaving the steel with low phosphorous and relatively high carbon content, or the carbon content may be reduced in a third stage in which bottom blowing is resumed.

W.; 138, South Country Club Drive, Schenectady, New York, U.S.A.) Dec. 29, 1930, No. 39090. Convention date, Dec. 28, 1929. [Class 39 (i).] A gastight s e a 1 consisting of a metal sleeve 5, a metal core 3, and a vitreous compound 4 interposed therebetween, is made by filling the sleeve with compound, heating the sleeve and compound to the softening temperature of the compound in an electric furnace, heating the core to a temperature about 75‹ C. in excess of said softening temperature and forcing the core into the compound. The seal is described in connection with lead-in conductors of mercury rectifiers, the lead-in conductor 2 to the anode 1 being screwed into a terminal portion 8 welded to the core 3. The compound consists of 50 per cent ground mica and approximately 50 per cent lead borate and is ground and heated to drive off oxygen and then compressed with a small quantity of water. This powder is forced into the sleeve 5 in a mould and heated until it is plastic, a small quantity being also heated in a cylindrical mould to form the head of the seal. The sleeve 5 and compound are then removed to a furnace at 200‹ C. below the temperature of the first oven and the head portion is placed on the compound in the sleeve 5. The heated core 3 is then pressed into the seal the whole being held at high pressure for about half an hour during which time the mould is allowed to cool. The sleeve 5 and core 3 are serrated to increase the leakage path and a shoulder 6 on the core 3 compresses the plastic material in the'sleeve 5. The core is of non-oxidizing material such as iron alloyed with 25 per cent chromium, and has substantially the same coefficient of expansion as the compound and the sleeve, which is of mild steel. Specification 318,555, [Class 39 (i), Electric lamps, Arc &c.], is referred to.
