Title: Index mark for maximum/minimum thermometers
Inventor: HOFMANN STEFAN
IPC: G01K1/06
Filed: 1983-12-22
Abstract: The invention relates to an index mark for maximum/minimum thermometers for fixing the highest and lowest temperature values in industry, meteorology, agriculture, the household and other areas. The aim is a reliable functionality of the index mark in the thermometer capillary and an optically effective readability. The object consists in developing an index mark with as low an inherent weight as possible, which by virtue of its design increases the tension at the surface of the display liquid at the contact surface to the meniscus. This is achieved according to the invention when the cross-sectional surface of the index mark facing the display liquid has a profile which subdivides the meniscus in the glass capillary into a multiplicity of individual meniscuses. It is preferable for the index mark according to the invention to consist of one or more hollow needles open at both ends and made from ferromagnetic or nonmetallic material, preferably plastics, ceramic or glass.
Patent DE-3346725-A1 (DE)
Title: Compensation circuit for a data modulator
Inventor: POETTER MANFRED DIPL ING
IPC: H04L27/233
Filed: 1983-12-23
Abstract: A demodulator circuit with a phase demodulator is proposed, which is used to demodulate a data-modulated RF signal transmitted with a limited bandwidth. To prevent corruption of the data contents of a demodulated data signal during data processing, the data signal supplied by the phase demodulator (17) is DC-decoupled according to the invention by means of a high-pass filter (28). The data signal thus obtained is regenerated by a comparator (23) by feeding a fixed reference voltage (URef) to a second input (24) of the comparator and by feeding the band-limited data signal supplied by the phase demodulator to the first input (22). The mean DC voltage value (UM) of the data signal is kept constant by means of a compensation circuit (19). <IMAGE>
Patent DE-3401799-A1 (DE)
Title: Hot mangle
Inventor: GEIGER FRIEDRICH DIPL ING
IPC: D06F67/08
Filed: 1984-01-19
Abstract: To increase the efectiveness of a hot mangle, the aim is to select the looping angle of the heatable trough (2) partially surrounding the mangle roller (1) as large as possible. This is counteracted by the reduction in diameter of the mangle roller (1) which occurs when the hot mangle is in continuous operation. The invention overcomes this problem in that stiffening ribs (4) surrounding the trough (2) on the outside transversely to the mangling direction are heated in their outer edge region. The stiffening ribs (4) consequently expand more on their periphery than at their small-area points of connection to the trough (2), thus leading to a contraction which reduces the diameter of the trough (2). The mangle roller (1) can thus be surrounded by the trough (2) over an angular sector of more than 180 DEG , without the penetration of the mangle roller (1) into the trough (2) being impeded. <IMAGE>

Title: Absorber rod drive for nuclear reactors
Inventor: ACHER HEINZ DIPL ING
IPC: G21C7/12
Filed: 1985-01-11
Abstract: The invention relates to a further development of the invention according to DE 3342838 A1. The figures included therein for identical parts have been adopted. The invention relates to the figures of the main application. The free bearing of the hollow piston against the nut caused by hydraulic pressure is replaced by a hydraulic or spring-releasable securement. This dispenses with the pressure system required for generating the hydraulic pressure and consequently the electric power always required for this for driving the pumps or the mass flow. The absorber rod, slit open in its longitudinal axis, is replaced by an absorber rod in the longitudinal axis of which the hollow piston is in common connection with the absorber rod. This makes the absorber rod more stable in itself and simplifies installation.

Patent DE-3625629-A1 (DE)
Title: Transport frame for pump units
IPC: E21F13/00
Filed: 1986-07-29
Abstract: Even sensitive units such as pump, coupling and motor connected to one another in the conveying direction can be conveyed underground on the monorail conveyor rail on a conveying frame since the lower support and the frame holding the units are each guided relative to one another and designed in such a way that the frame slides into the horizontal or remains in this horizontal position in the event of a corresponding inclination of the lower support. For this purpose, the lower support is bent in the form of a circular arc, has two U-shaped rails which are arranged with the flanks against one another and hold running wheels assigned to the frame and at the same time guide these wheels. In the event of a corresponding inclination of the conveying frame, the frame supporting the sensitive units thus moves automatically into the horizontal and remains there until the conveying frame assumes a different angle. According to another design, the bent support is arranged outside the rectangular framework and above the latter and is itself connected to the crabs. The upper support of the rectangular framework is equipped with running-wheel pairs on an attachment, which pairs can roll in this support, which forms a track with a concave curvature in the direction of the roof. Such a design has an advantageously small overall height. <IMAGE>

Title: Automatic inspection of textile webs
Inventor: MASSEN ROBERT PROF DR ING
IPC: D06H3/08
Filed: 1986-11-20
Abstract: The invention relates to a method and a circuit arrangement for automatic inspection of plane fabric webs by means of a parallel arrangement of colour-area cameras. The inspection is based on colour-defect recognition carried out in real time, at the same time as local structural-defect recognition carried out in real time, and on 2-dimensional image evaluation initiated in the event of unreliable recognition results and no longer carried out in real time. Colour-defect recognition is based on a classification carried out by means of a colour-feature memory, and structural-defect recognition makes use of a cyclically written transient-image memory for the more accurate 2-dimensional grey-value evaluation in the event of defects recognised unreliably in the local region.

Abstract: Owing to the compression and expansion phase produced in a rotation of the slide, the entire assembly is a two-stroke heat engine. Due to the good blocking function between the differential pressures, a displacement effect is achieved in the rotation, making the same assembly suitable for drive functions and for compression functions.  Design advantages     1.) Simple construction with few moving parts.   2.) Acceleration of the masses in one direction.   3.) Thrust power in one direction. 4.) Rotating drum provides the function for blocking element and charging element, and output, cooling, lubrication and flywheel. 5.) Low residual gas retention and hence good fresh-gas charging, due to small clearance. 6.) Good mixing of the charge, and heat division into reaction heat and compression heat by virtue of the two assemblies.
