Patent DE-3121442-A1 (DE)
Title: Method for controlling the temperature of steam flowing in a line by injection, and arrangement for implementing the method
Inventor: SAUERLAND WERNER ING GRAD
IPC: F01K3/00
Filed: 1981-05-29
Abstract: When controlling the temperature of a flowing steam in which, as a function of a predefined steam temperature setpoint, an injection medium is injected, controlled in its amount by the change in temperature, there is the risk, owing to transient phenomena or major effects of disturbance variables, of the amount of injection medium being subject to undershooting or overshooting. In order to reduce the deviations of the steam temperature it is proposed that the measured temperature and the pressure of the inflowing steam are employed to determine the enthalpy of the steam, that the predefined setpoint of the desired steam temperature behind the injection point of the injection medium, and the pressure of the outflowing steam are employed to determine the enthalpy behind the injection point,  that the enthalpy of the injection medium is determined and that the measured amount of steam flowing in, the difference of the steam enthalpies upstream and downstream of the injection point, and the difference of the steam enthalpy behind the injection point and the enthalpy of the injection medium is employed to determine the setpoint for the injection medium amount and is used as a guidance setpoint for the quantitative control of the injection medium. <IMAGE>

Patent DE-3132643-A1 (DE)
Title: Hydrostatic unit
Inventor: EICKMANN KARL
IPC: F04B9/10
Filed: 1981-08-18
Abstract: In the housing of a hydrostatic unit at least two mutually sealed chambers are arranged, which can be acted upon by differing first and second pressures in the first or the second chamber. Generally, however, there is also arranged a third chamber with a third pressure. The unit may also contain a pump and a motor, the use of radial chamber units, particularly radial piston units being preferred in order to achieve a short construction. A proven embodiment of the unit is pressure transmission, that is a pressure transformer in which, for example, the motor drives a high pressure pump. The unit can then be used in a pressure line and can then convert a low or medium pressure into a high or super pressure where it is required remote from the first pump. According to further embodiments of the unit it can deliver different fluid flows with different flow behaviour and thereby drive machinery, vibrators, presses, moulds, reciprocating units etc., particularly with units operated and driven by it, and actuate additional controls or feeds.

Title: Apparatus for the production of metal strip from a melt
Inventor: HILZINGER REINER DR
IPC: B22D11/06
Filed: 1981-09-12
Abstract: To produce a narrow strip (1) directly from a melt (3), the so-called melt-spinning process is known. In this process, molten metal emerges from a nozzle (4) and flows against a moving surface (6) of a cooling roller (7). The apparatus according to the invention makes it possible to produce such strips, composed of a metal alloy, with a relatively large thickness - up to about 0.2 mm - from the melt (3) without solidification of the melt in the nozzle (4) due to excessively slow movement of the cooling roller (7). The solution consists essentially in a slot-shaped nozzle opening, the larger dimension of which lies in the direction of motion of the cooling roller (7), and in the fact that the surface (6) of the cooling roller is wide relative to the narrow dimension of the outlet cross-section for the melt. This apparatus is suitable particularly for the production of amorphous starting material for springs. <IMAGE>

Abstract: The circuit current of a direct converter (24U, 24V, 24W) is split and controlled in each phase such that the circuit current in a phase having a large absolute magnitude of the load current is small, and the circuit current in a phase having a small absolute magnitude of the load current is large. This compensates for the reactive power such that the sum of the lagging reactive powers in the phases and the leading reactive power of the phase-advanced capacitor (31) cancel one another out. <IMAGE>
Patent DE-3140821-A1 (DE)
Title: Device for heating liquids
IPC: F24H1/28
Filed: 1981-10-09
Abstract: For heating a liquid needed for a heating installation, it can as is known be filled into an inner and outer boiler which are arranged in the form of a combustion chamber with boiler circuit pump. To achieve an advantageous degree of efficiency, low-temperature operation is sought in this connection, with which the liquid is not heated more than is absolutely necessary. Then, however, the boiler walls themselves also have only a relatively low temperature, so that the flue gases flowing past condense. The sulphurous acid arising in this connection leads to corrosion damage. In the case of the invention, the outer boiler is designed in the manner of a pot with a bottom space which receives the liquid and which is connected to the inner boiler. The latter is moreover, in the region of the forward run connection for the heating installation, connected to the outer boiler via a throttle so that a circulation of the liquid according to the principle of gravitational force can take place. The temperature of the boiler walls flowed against by the flue gases is, on account of the relatively slow flow of the liquid, considerably higher than the temperature of the liquid, so that the dew point of the flue gases is not fallen below. As a result, the desired low-temperature operation is possible practically without limitation of a minimum temperature.

Title: Scintillation camera
Inventor: NISHIKAWA MINEKI
IPC: G01T1/164
Filed: 1981-10-16
Abstract: The invention relates to a scintillation camera in which reference correction quantities are stored in advance at grid points in a predetermined matrix in accordance with position signals which are supplied by a radiation position calculating circuit (5), the position signal supplied by this circuit (5) is subjected to an A/D conversion with each scintillation process, a correction quantity with respect to a point is calculated with coordinates on the basis of the reference correction quantity at each grid point in a unit grid area, the grid points enclosing the point on the coordinates which corresponds to the digital position signal, and the correction quantity is added to the position signals supplied by the calculating circuit (5). This scintillation camera is characterised by the fact that two random number generators (17, 18) supply first and second independent random data with each scintillation process, which are added as lower-significance bits to X and Y components in the position signal, and the correction quantity at the point on the coordinates is calculated by using these added data for or as measurement position signal. <IMAGE>
