Patent DE-3119862-A1 (DE)
Title: Tubular heat exchanger
Inventor: MEISSINGER HERBERT
IPC: F28D7/02
Filed: 1981-05-19
Abstract: In order to construct a three-dimensional heat exchange member, which can easily be adapted to different tasks, in a simple way in the case of a tubular heat exchanger, in particular for use in a container which can be filled with a heat exchange (transfer) fluid, which has flexible, coiled tubes for a second heat exchange fluid which are arranged at a distance from one another and are formed by coherent longitudinal regions of a flexible battery (coil), it being the case that the position of the longitudinal regions relative to one another is fixed by rigid, rod-like retaining means, which are arranged parallel to one another and perpendicular to the coiling direction of the battery or by strips (bands) extending in the coiling direction of the battery, the retaining means are formed by supporting cross struts (1, 2) which cross one another diagonally and on which there are arranged supporting longitudinal rails (3, 4, 5, 6) extending in parallel, and the battery (7) is mounted on the supporting cross struts (1, 2) and the supporting longitudinal rails (3 to 6) in the fashion of a spiral helix and succeeding one another vertically. In a further embodiment, the battery sections (8) can be arranged like discs in the shape of a spiral, and it is possible to provide in the vertical horizontal discs succeeding one another in which battery sections are arranged in the shape of a spiral. It is possible by means of this construction for the length of the battery and the arrangement of the individual sections to be selected arbitrarily, and the battery surfaces are offset in the radial and axial directions of flow through the heat exchanger in such a way that the sections are not situated, or are situated only to a slight extent, in the flow shadows of the adjacent sections. <IMAGE>

Title: Horizontal drive for a recording head
Inventor: JOHANNSEN FRED ING GRAD
IPC: B41J19/20
Filed: 1981-06-06
Abstract: The print head (2) can be moved continuously and incrementally in guide rods (3) in the line direction. A motor-driven guiding spindle (7) is used for its adjustment and is connected rigidly to the motor shaft (10) and the timing disc (9). The connection between the guiding spindle and the carriage (1) bearing the print head is produced by a guiding nut (13) which engages with a projection (22) in a recess (15) on the carriage and at the same time is supported against being rotated by the guiding spindle by engagement on a guide rod. This prevents vibrations of conventional drive systems with transmission wire, toothed belt or spindle being transmitted to the carriage and thus to the print head. <IMAGE>

Title: Sealing device and pressure-tight transfer mechanism
Inventor: SUKEGAWA HIROMU
IPC: B32B15/08
Filed: 1981-06-09
Abstract: Sealing device for pressure-tight sealing between a fixed element and a movable element. The sealing device comprises a flexible sealing element on which two opposite rims are formed, one of which is attached to the fixed element and the other rests against the movable element and is in contact with it. A free part of the flexible sealing element between the two rims of the latter is essentially rolled up, more specifically in a direction from the free part of the flexible sealing element nearest to the fixed rim towards the free part of the sealing element nearest to the rim in contact with the movable element. A first space is divided off on the essentially concave side of the flexible sealing element and a second space is divided off on the essentially convex side of the flexible sealing element. A higher fluid pressure in the first space presses the contact rim of the flexible sealing element firmly against the movable element. A description is also given of a pressure-tight transfer mechanism for the transfer of a plate between a space at higher pressure and a space at lower pressure, the transfer mechanism having two rollers in contact with one another and two sealing devices according to the invention.

Patent DE-3204379-A1 (DE)
Title: A measuring method for determining the noise temperature of a two-terminal network, independently of its impedance
Inventor: SCHIEK BURKHARD PROF DR ING
IPC: G01R29/26
Filed: 1982-02-09
Abstract: The invention relates to a measuring method for determining the noise temperature of a two-terminal network, independently of its impedance, and a noise temperature measuring device for carrying out the method. The input ports of a compensating radiometer of conventional construction (for example thickness radiometer, correlation radiometer) are connected, according to Figure 1, to a circuit consisting of two couplers (K1, K2), two reference noise sources (R1, R2), an auxiliary noise source (R3) and the attenuating section (D) and the object being measured (MO). Further developments relate to the preamplifiers used in the radiometer in order to reduce the influence of their inherent noise on the measurement result. In contrast to methods previously known, it is possible, using this measuring system, to determine the noise temperature of mismatched two-terminal networks without a circulator or other passive non-reciprocal components being needed. The method is therefore particularly suitable for measurements in a frequency range below 1 GHz.

Patent DE-3220201-A1 (DE)
Title: Adaptor for connecting nozzles
Inventor: FIEBICH HUBERT ING
IPC: F16L37/12
Filed: 1982-05-26
Abstract: The invention relates to an adaptor for connecting nozzles, as can be used, for example, for the attachment of the water supply hose to washing machines. In the manufacture of specific apparatuses which operate with heated or pressurised media such as water, oil or gas (washing machines and dishwashers, water coolers for internal-combustion engines, hydraulic systems and the like) it is necessary during the final check of the complete apparatuses to supply several hundred or thousand apparatuses with the medium briefly during one working day, in order to be able to carry out a test run. In this case, it is intended to be possible to make the connection to the supply source of the medium as quickly as possible. This is achieved by means of the adaptor according to the invention. Said adaptor is characterised by a housing which is simultaneously used as a handle, within which the pipe piece which is connected to the supply line is supported such that it can be displaced axially and is surrounded by three or more plates having a cross-section in the shape of an annular sector, which plates have an inner profile in their front section matching the outer profile of the connecting nozzle, and partially emerge out of the housing when the housing is pushed to the rear with the pipe piece held fixed, and spread out, and return into the housing by reversing the displacement, with the profile engaging in the connecting nozzle.
