Enables the periodic release of pressure, which can build up due to thermal expansion of the stored liquid or contraction of the cavity in the rock salt and can damage the surface shut-off valves or the overburden, to be carried out solely on the stored liquid side, thus eliminating corrosion by the brine.
Patent DE-2338912-A1 (DE)
Title: Dispensing valve for granulated material - displaceable tube cooperates with conical closure plug
Inventor: WEHNL HELMUT
IPC: F16K41/10
Filed: 1973-08-01
Abstract: A dispensing valve for granulated or powder materials conveyed through pipes, has a sliding metal tube connected concentrically with a hollow piston. The piston is moved in a bore in a housing under a pressure differential established across it via two ports. At one end the housing supports a fixed conical plug which can seal the end of the tube. The pressure fluid is prevented from contacting the tube by corrugated bellows which may be pressurised with an inert gas via duct. Air jets prevent granulated material accumulating on the plug. Conventional piston ring seals are used throughout the construction and allow high temperature operation about 200 deg.C.

Title: Co-ordinate digitiser for automatic reading of technical drawings - inductive sensor provides measured position using two wire loop arrays
Inventor: JUHASZ ANDRAS
IPC: G06F3/046
Filed: 1975-01-03
Abstract: A co-ordinate digitiser for use with computerized systems for the reading of technical drawings utilises an inductive sensor. A number of conducting wire loops are arranged in columns with a fixed distance between each other. The loops are located on a plate over which is located a cylindrical coil with a continuously supplied alternating current winding. The sensor loops are represented by two pairs such that when magnetic field is moved the direction of motion may be determined. Comparison of phase between the two loops enables the position to be determined. Two such sensing arrangements located perpendicular to each other provide a full two axis co-ordinate digitisation.

Title: Reducing emission of nitrogen oxides in catalyst mfr.
Inventor: FEINS IRVIN RALPH
IPC: B01J27/24
Filed: 1975-01-22
Abstract: This process is for reducing the amt. of nitrogen oxides emitted during the calcination of a catalyst carrier which contains a source of nitrogen oxides. The novelty is that, prior to calcination, the carrier is treated with sufficient urea to suppress the formation of nitrogen oxides during calcining. The urea is pref. added to a catalyst promoter soln. used to impregnate the shaped carrier, the addn. being made when to a mixt. being prepd. in a chaser- or chilean mill. The process is intended for use in the mfr. of catalysts which contain nitrates and which can therefore result in environmental contamination when the catalyst is calcined on the carrier. The catalysts are used to prevent environmental contamination by the exhaust gas from internal combustion engines, esp. motor cars
