Title: A process and photographic material for the production of photographic records and copies which are corrected for tone valne
IPC: G03C1/46
Filed: 1958-02-12
Abstract: 884,251. Photographic materials and processes for tone value correction. AGFA A.G. Feb. 12, 1958 [Feb. 12, 1957], No. 4629/58. Drawings to Specification. Class 98(2). A photographic material comprises an image-forming (described in the Specification as "continuous tone") silver halide emulsion and a less sensitive silver halide emulsion for producing a tone value mask, these emulsions being sensitive in the same regions of the spectrum but the ratio of the sensitivities of these emulsions not being constant over the entire common sensitivity range. The emulsions may be in separate layers on a support, or may be in the form of a mixed emulsion, the gradation and sensitivity of the two emulsions responding separately to light of different wave lengths. The emulsions may be sensitive to the blue and green parts of the spectrum. Exposure may be to an object or image and processing to silver, dye or silver-containing dye, and in the latter two cases the processed material may be copied with two types of light simultaneously or successively on to material sensitive to both types of light, such as the same type of material originally used for the exposure, to result in a picture corrected as regards both shadow and highlight definition. Example 1 describes somewhat mathematically with reference to drawings (not shown), a continuous tone gelatino-silver bromoiodide layer and a masking gelatinosilver chlorobromide layer of 1 /30 sensitivity of the continuous tone layer, both layers being orthochromatic but the continuous tone layer having pronounced sensitivity in the green region and the masking layer having pronounced sensitivity in the blue region; and describes exposure of these with unfiltered light, and with blue and yellow lights which latter affect respectively masking and continuous tone layers more strongly. In Example 2 the continuous tone layer has 4 times sensitivity to green light than to blue and the masking layer of lower inherent sensitivity has equal sensitivity to blue and green, and such is stated to have advantages when used as exposure material as by arc light to a black and white continuous tone original via a reproduction camera, and additional advantages when used as copying material with coloured light. Example 3 specifies emulsions for the two layers, indicates exposure and processing as in Example 2 to produce a tone-value corrected image in silver, and continues with description of bleaching and colour developing this image to one of yellow dye and silver, which latter is printed by green and blue light on to the same two-layer material to give a result corrected for tone value in high lights and shadows. Specifications 799,590, 819,041, 845,217 and 878,487 are referred to.

Abstract: 1,048,216. Centrifugal pumps. METAL PUMPING SERVICES Inc. Feb. 4, 1964 [Feb. 6, 1963], No. 4743/64. Heading F1C. A pump comprises a hollow body defining a chamber providing communication between inlet and outlet openings, pumping means co-operating with the chamber and the openings to draw a liquid stream into the inlet opening and through the chamber and discharge it through the outlet opening, and a deflector disc mounted for rotation about an axis of the inlet opening, the disc and the periphery of the inlet opening being spaced apart by a distance less than the maximum dimension of solid particles capable of passing into and through the pump with the liquid stream. A centrifugal pump for submersion in a bath of the molten metal to be pumped comprises an impeller 20 screw-threaded on to a shaft 22 and journalled in a bore 18 in a casing 16. A rotating deflector disc 26, screw-threaded on to the shaft 22 and spaced a distance S from the bottom surface 23 of the casing 16, throws large solid particles aside and prevents them from entering the pump and clogging or damaging it. Agglomerates of solid or semisolid particles are similarly deflected or are broken up so that they can pass freely through the pump. The diameter of the deflector disc 26 is at least substantially the same as that of the bore 18 and may be substantially larger. An additional or alternative inlet, provided with a deflector disc, may be located at the top of the casing 16. Instead of being located outside the inlet, the deflector disc may be located within the inlet and made smaller in diameter than the inlet to provide a radial clearance corresponding to the axial clearance S. To resist corrosive attack by the molten metal, the impeller, casing, shaft and the discharge pipe (not shown) are formed from, say, graphite, carbon, silicon carbide or aluminium silicate or bonded mixtures of such materials. If graphite is used, at least the peripheral portion of the deflector disc may be of silicon carbide to resist abrasion.

Abstract: 212,249. Freund, E., and Brociner, S. Dec. 19, 1921, [Convention date]. Addition to 190,490. Metering systems. - When a connection has been established, a preliminary talking circuit is completed for a few seconds only during which the calling subscriber may ascertain the correctness of the connection. If during this interval the calling subscriber operates his meter or starts his time-recording device, the cutting-off threat is removed and a permanent talking connection established. The Figure shows the invention applied to a semi-automatic connection between two subscribers A, B. When the called subscriber B replies, the feed-relays f, g complete a circuit S, 1, 2, 3, 4 for a relay Z controlling a timing-apparatus, which threatens to cut off the connection at the end of 10 seconds. The depression of metering key ZT during this interval short-circuits relay f thus opening the circuit of the timing-relay Z. The Specification as open to inspection under Sect. 91 (3) (a) states that in a time-controlled system, conversations can be extended beyond the regular time by operating the metering-key again before the previous stage is exhausted, and comprises also the application of the invention to a manual exchange, and a semi-automatic system which is identical with a system described in the parent case as open to inspection under Sect. 91 (3) (a). This subject-matter does not appear in the Specification as accepted.
