Title: Automatic valve for the rapid emptying of a hydraulic medium from a space under excessive pressure
Inventor: DAMS JOERN
IPC: F15B13/02
Filed: 1985-06-01
Granted: 1986-11-20
Abstract: The invention relates to a multi-way valve for returning fluids from a cylinder of a hydraulic system which has a valve housing with three connections as well as a valve body displaceable therein against the force of a spring. The object of the invention is to create a multi-way valve of the generic category mentioned at the beginning which is distinguished by a well-defined operating position and ensures rapid emptying of a hydraulic medium from a space under excessive pressure both via the second connection to the tank and via the first connection towards the control unit. This object is essentially achieved according to the invention in that the valve body (22), irrespective of its operating position with regard to the second connection (2) to the tank (8), has at least one continuous passage (24, 25) constantly connecting the first connection (1) to the third connection (3), and in that the valve spring (21), in the position of the valve body (22) open to the tank (8), is provided with a preloading force which is greater than the sum of all friction forces acting on the valve body (22). <IMAGE>

Abstract: In order to radically improve the efficiency of evaporators used in vacuum foil coating plants wherein reactive metals such as Al, Ni, Fe and the like are being evaporated, a radiation heater heated up to about 2500 DEG  C. is placed in a cavity, the inner wall surface of which carries the liquid evaporant. The liquid evaporant is evaporated and energized by the radiation heater emitting high energy photons and also electrons. The high energy vapor is directed in a beam and reduces evaporant waste caused by stray deposits, and also forms a denser metallic coating on a moving foil being metallized.

Title: Method for controlling the solidification and cooling conditions for cast iron castings
Inventor: LINDSCHEID HELMAR DR-ING
IPC: B22D27/04
Filed: 1987-04-25
Granted: 1988-08-18
Abstract: Cooling blocks (2) are employed as cooling elements for controlled cooling of a cast-iron melt or casting (1). As an additional component in a jacket (3) of high thermal conductivity, these blocks contain a material (4) which melts or solidifies between 650 and 800@C. The heat of fusion of the material (4) additionally absorbed by this component of the cooling block (2) accelerates the cooling of the cast-iron melt and of the casting (1) in the overheating and solidification range. The heat of solidification given off by the fused component (4) - aluminium or a copper/tin alloy for example - during the process of further cooling delays the cooling of the casting (1) in the eutectoid transformation range at about 690 to 750@C and therefore makes possible the formation of a ferritic structure in the casting (1). <IMAGE>
Patent DE-3936542-C1 (DE)

Filed: 1989-11-02
Granted: 1991-04-11
Abstract: An indicator for mounting on objects displays time-lapses and/or the onset of changes of state. A visible display is obtained by means of a colour change in the indicator or the like produced by reaction of chemical substances, accompanied by destruction of one of the barriers initially separating the chemical substances. The barrier is a separating or covering layer which can be penetrated by local corrosion by a chemical substance initially enclosed by the barrier. In one embodiment, a surface appears following local corrosion, accompanied by a visible change in the indicator. In another embodiment, the barrier separates two chemical substances which can react with each other to produce a visible change, at least one of which penetrates the barrier in order to react with it.

Patent DE-4126341-C1 (DE)
IPC: A61M1/02
Filed: 1991-08-09
Granted: 1993-01-28
Abstract: In a device (10) for separating blood the haematocrit value of the blood to be separated plays an important role for sedimentation of cellular blood constituents. Due to the fact that considerable fluctuations of the baseline haematocrit value of the blood may occur, especially in the intraoperative field, during processing of blood, for example as a result of infused volume expanders, irrigation solutions, added anticoagulants and the like, it is expedient to include the predetermined haematocrit value of the blood to be separated in the separation process, in order to maintain the blood separation at constant values, in particular with a constant haematocrit value of the erythrocyte fraction. According to the invention, the amount of blood flowing through the separating device (10) is automatically adjusted as a function of the haematocrit value of the blood supplied.

Title: Measuring apparatus for calorimetric determination of the AC losses of superconductors
Inventor: SCHMIDT CURT DR
IPC: G01N25/18
Filed: 1993-06-22
Granted: 1994-10-20
Abstract: The invention relates to a measuring apparatus for determining the AC losses of superconductors in AC magnetic fields of arbitrary frequency. The measuring apparatus consists of a cylindrically shaped sample holder on which the superconductor to be measured is wound. During the measurement, the sample is surrounded by a medium, having low thermal conductivity, which serves as a thermal resistance with respect to the surrounding liquid helium bath. The applied AC field leads to an increase in the temperature of the sample, which increase is a measure of the losses. Using a heating device, the same heating as with the application of the AC magnetic field can be produced, by means of which the AC losses of the superconductor can be ascertained. The series measurement of samples can therefore be carried out with low time expenditure.
