Title: Device for the controlled supply of liquid
IPC: G03D3/06
Filed: 1962-08-07
Abstract: 973,310. Liquid level control. AGFA A.G. Aug. 7, 1962 [Aug. 4, 1961], No. 30258/62. Heading G1H. In a liquid supply control device in which there is included in a liquid supply line a main valve controlled by a limiting device to give predetermined intermittent opening periods, a flow regulator in the liquid line downstream of the main valve and a float valve in the liquid line upstream of the main valve and of a predetermined height above the working level of the supplied liquid the arrangement is such that the liquid drains from the float valve at a greater rate than it eners such float valve. In the arrangement shown in Fig. 1 liquid is fed from a storage tank 8, by means of air under pressure from a compressor 12 acting on a float 13, through a hose 14 to a chamber 15 arranged at a higher level than process tanks 1. The chambers 15, shown in Fig. 2, of a transparent synthetic plastic, is closed by a cover 23 provided with an upper extension 24 closed by a cap 26 and housing a centrally located perforated tube 27 which reduces the velocity of the in-flowing liquid through the elbow 28 from the tank 8. A lower tubular extension 25 co-operates with a cone 30 on a float 31 which is guided in the chamber 15 with lateral play to allow liquid entering above the float 31 to pass through a pipe 19, hose 21, solenoid operated valve 20, an interchangeable nozzle 33 and a pipe 34 to the inside of thechamber 2 above the liquid level 35 therein. The construction of the chamber 15 is such that the liquid fed thereto cannot equal the speed of the liquid draining therefrom. Liquid is fed from the chamber 2 into the chamber 1 by a pump vane 4, driven by a motor 3, forcing liquid downwardly in a cylinder 5 and through a pipe 6. In the arrangement shown in Fig. 3 two switches 36, 37 are provided in the circuit of the solenoid valve 20. The switch 36 is provided with a roller 39 situated in the path of a photographic paper 38 to be developed and closes automatically when the paper is tensioned so that liquid delivery can only take place while the paper 38 is present. A timer 45 transmits switching impulses to a motor 40, which drives the shaft 42, to close the switch 37 by means of cams 42, 43. The cams 42, 43 are displaceable relative to one another in a rotary manner on the shaft 42 to alter the actuating period of the switch 37 and thus the opening period of the valve 20. The interchangeable nozzles 33 can have varying cross-sections or flow resistance since individual developing baths require different amounts of liquid from the storage tank 8 for a unit of time. A throttle valve may however replace each nozzle 33.

Title: Improvements relating to the recovery of silver from solutions
IPC: C01G5/00
Filed: 1946-10-15
Abstract: Solutions containing a silver thiosulphate anionic complex are brought into contact with an anion exchange in salt form to cause exchange of the anionic complex, and the silver is removed from the exchanger by treatment with an acid, e.g. nitric acid, or salt, e.g. potassium carbonate, ammonium carbonate or nitrate, sodium sulphate or chloride, or base, e.g. ammonium or sodium hydroxide, or alternatively in metallic form by combustion of the exchanger.  The silver solutions employed mostly derive from photographic processes; other solutions containing silver in cationic form are first treated with sodium, e.g. thiosulphate. Suitable exchangers are aniline black, aromatic amine-formaldehyde resins, basic melamine resins and aliphatic amine resins such as prepared from the polyalkylenepolyamines.  An example relates to a resin prepared from formaldehyde, acetone and tetraethylene pentamine by the process of Specification 572,836, [Group I].
