IPC: G03D7/00
Filed: 1949-01-31
Abstract: 657,201. Photographic gas-developing apparatus. OZALID CO., Ltd., and REYNOLDS, E. H. Jan. 31, 1949, No. 2626. Drawings to Specification. [Class 98 (ii)] In apparatus employing a developing gas or vapour which gives rise to obnoxious exhaust fumes, the waste developing gas or vapour exhausted from the machine is subjected to chemical reaction to decompose it into physiologically inactive substances. As described, waste ammonia leaking from the developing chamber and evaporating from the developed prints is drawn off from the hood surrounding the machine by a motor-driven fan and passes along the extraction duct over granular black copper oxide packed in a tube and heated by a surrounding electric element to 400-500‹ C., when the ammonia is decomposed into nitrogen and water with reduction of the oxide. Periodically the waste ammonia is first passed over a platinum wire electric heating coil in the extraction duct which has been raised to about 500‹ C., when the ammonia is catalytically decomposed into water and oxides of nitrogen which re-oxidise the reduced copper to the black oxide. Both the oxide tube and that housing the platinum catalyst, which tube may also carry an external heating element, may be surrounded by asbestos lagging, and baffles may be inserted in them to lengthen the path of the waste gas. Other suitable oxides are those of chromium, molybdenum, tungsten, titanium, tin, lead, silver, manganese, iron, nickel, and cobalt, in particular lead dioxide, manganese dioxide and nickel monoxide, while the catalyst may alternatively be platinum, osmium or nickel on asbestos fibre, platinum on quartz, or platinum-plated nickel gauze. The motor driving the exhaust fan may also drive through reduction gearing the lower of the two rollers driving a belt which advances the prints upwardly across the perforated inclined wall of the developing chamber. Specification 495,392 is referred to.

Abstract: 682,569. Multiplex systems. TELEFONBAU UND NORMALZEIT GES. Feb. 6, 1951 [Feb. 24, 1950; Oct. 19, 1950], No. 2886/51. Class 40 (iv). In a system for compressing and dovetailing successive portions of a plurality of communication signals, a moving magnetic tape T receives the signals from n (=6 as shown) recording heads S and then passes n rotating, pick-ups HA (which may rotate in either direction) connected to a common output circuit, the heads being angularly staggered to lie on a helix. The tape is arranged to contact a drum over the area on which pick-up is to take place, the arcuate sweep being 1/n of the circumference of the drum, where n equals the number of pick-ups and also equals the ratio of the relative velocity between pick-up and tape to the tape velocity. By this means successive pick-ups commence reception immediately on cessation of reception by the preceding pickup. In the reconversion equipment incoming signals are fed to n rotating recording heads located immediately below the corresponding pick-ups and recording on portions of the tape which then pass n pick-ups H feeding corresponding output channels. In a modification, Fig. 4 (not shown), the upper portion of the tape is used for compression and dovetailing and the bottom half for the reconversion process. Since all signals in the common channel will lie above the audio range, this range may be used for sending synchronizing signals between the compression and reconversion equipment.
