Patent DE-4034719-A1 (DE)
Inventor: SCHEUERMANN KLAUS
IPC: G21F7/005
Filed: 1990-11-01
Abstract: The object of the invention is a shielding cover (1) containing a tackle line (14), the end of which is secured with a claw (13) inside the shielding cover. The claw (13) is designed to grasp baskets (19) with radioactive materials like waste which are to be stored in a container (10) arranged beneath the shielding cover and is closable with a lid (20). The lid (20) is used at the same time as the closure for the shielding cover (1). The shielding cover (1) contains a laterally projecting housing section (4). In this section (4) the lid (20) is arranged to move between two end positions transversely to the longitudinal axis (6) of the shielding cover (1). In one end position the lid (20) reveals a lower aperture (8) in the shielding cover (1). In the other end position the lid (20) closes off the shielding cover (1). A fluid acceptance tank (44) is also arranged to move between two end positions in the housing section (4) beneath the lid (20). While the fluid acceptance tank (44) reveals the aperture (8) in one end position, it covers it in the other.

Title: Offset and response compensation of line or matrix detectors
Inventor: BUECHTEMANN WOLF DIPL PHYS DR
IPC: H04N1/195
Filed: 1990-12-12
Abstract: The line or mosaic detector used for thermal image processing has a facility for compensation to reduce the effect of the so called Aliasing phensmenon. As two detectors (1,2) are moved between positions (1'-n') differences of voltage (U) are apparent.     As one detector (1) moves to the position previously associated with the other (2) an offset voltage difference exists. The process eliminates the difference to harmonise the output.
Patent DE-4040202-A1 (DE)
Inventor: BECHTOLD DIETER
IPC: H01M10/10
Filed: 1990-12-15
Abstract: The preparation of the solid gel electrolyte, which usually follows the pouring of the initially liquid sulphuric acid into the finished storage battery fitted with charged positive and negative electrodes, can be associated with the formation process by finally installing the still unformed plates (blanks), fitting the final current terminals (poles, pole bridges) and forming with a sulphuric acid which is dilute but which already contains the gel former in the form of finely dispersed silica. After the formation process has been carried out under conditions which are otherwise also conventional in the case of batteries containing liquid electrolyte, the storage battery is ready for use and contains an immobilised electrolyte.

Title: Outputting characters, esp. to dot matrix printer - using standard character generator with synthesiser for special character sets
Inventor: STENGEL KARL DIPL PHYS
IPC: G09G5/24
Filed: 1991-01-21
Abstract: Characters are selected from a character generator according to at least one character request. Character detection and selection devices select a first character from the generator depending on the request, place it in a character synthesiser and select at least one further character and place this in the synthesiser. The synthesiser combines the first character with the one or more further characters and outputs a new character resulting from the combination. Capitals of reduced height can be placed in the generator and/or in an additional character generator. USE/ADVANTAGE - For outputting characters to display or printer, esp. dot matrix printer. Enables correct representation of special characters without expanding conventional character generator.

Patent DE-4103690-A1 (DE)
Title: Injection mould for stepped precision parts, e.g. gear clusters - has stacked disc inserts of equal outside dia. each comprising one dia. of cavity for improved accuracy with spark erosion
Inventor: TROESCHER HERBERT
IPC: B29C45/37
Filed: 1991-02-07
Abstract: Injection mould for precision parts having several co-axial diameters, in which the mould inserts (17,18) are composed of a number of discs (19 to 22,24,25), each of thickness corresp. to a single step or dia. of the moulding (3' to 8'), and with equal outside diameters (15,16) mating with a corresponding bore in the mould plate(s) (9,10). Tangential alignment is maintained by a radial key fitting closely in corresponding locating slots in the mould plate (9) and insert discs (19 to 22). The parts of the cavity and locating slots are spark-eroded. USE/ADVANTAGE - Moulding precision parts e.g. gears and gear clusters, for wristwatches and similar mechanisms. Normally the mould parting line occurs at the largest part diameter, so that in a one-piece insert, the smallest diameters are furthest from the insert face. Even when the cavity is closed by a separate plate, the span of the electrode wire between guides must be greater than the total insert thickness, with loss of accuracy due to deflection of the wire. This span is reduced to slightly greater than the length of the corresp. part of the moulding, giving increased accuracy. The common outside diameter and tangential key ensure accurate alignment of the parts of the cavity. The arrangement permits several cavities in a single composite insert. The disc inserts are simpler, cheaper and more accurately manufactured than the usual one-piece ("potshaped") inserts.
Patent DE-4104581-A1 (DE)
Title: Space framework with cylindrical girth and diagonal tubular bars - has node connection with ball with screw union between ball and tubular bar end narrowing towards it
Inventor: MYLAEUS ARMIN
IPC: E04B1/19
Filed: 1991-02-14
Abstract: The node connection has a ball (3), a threaded bolt, a drive muff (69) and a conical transition piece (4a) at the end of a cylindrical tubular bar (4). In the ball are several radially directed holes (3a) with inner threads (3b). The threaded belt has on the tubular bar side an outer thread, and a like thread on the ball side. The tubular bar side outer thread has a smaller pitch and a greater dia. than that on the ball side. It also corresponds to the inner thread (4c) of the transition piece (4a) and the ball side outer thread corresponds to the inner thread (3b) of the ball (3). The central area of the bolt, which occupies approximately a third of its length, corresponds in dia. to the dia. of the tubular bar side outer thread, whereby this latter thread can also extend over the central bolt area. USE/ADVANTAGE - A space from work with ball nodes in which the connecting means are virtually invisible.

Patent DE-4105877-A1 (DE)
Title: Electromagnetic recording head with improved wear properties - uses glass compsn. with much higher hardness value but low softening point
Inventor: OHATA TSUKASA
IPC: C03C3/074
Filed: 1991-02-25
Abstract: The electromagnetic recording head features 2 half cores with a magnetic gap between them over which the magnetic tape passes. The cores contain a glass material in each half with the compsn.: PbO 72-75 wt.%, B2O2 15-20 wt.%, SiO2 2-3 wt.%, ZnO 5-7 wt.% and Al2O3 0-1 wt.%. The amorphous material is formed as a layer on a surface shaped like a truncated pyramid. The truncation is of such a size that a gap of the correct length (TD) is formed by grinding and lapping. The core halves are connected together by the low melting glass (46). The Vickers hardness of the glass layer (46) is pref. 330-350 HV and the bending strength 40-50 g. The magnetic material (40) used in the head oref. contains Co, especially an alloy of Co-Nb-Zr. The insulating material used (42) is pref. SiO2.  A barrier layer (44) is used, pref. of Cr. The core halves are formed by first forming a pyramidal surface in a ferrite substrate material. Then the angular surface is coated in succession with a layer of amorphous magnetic material (40), insulating layer, barrier layer and glass layer. The surface is then truncated by grinding and lapping. USE/ADVANTAGE - The glass shows a much improved wear-out performance. It works satisfactorily even at high temperature and high humidity. The glass softening temp. is the same as for the currently used glasses and the glass does not react with the magnetic material. The low softening point allows the  glass to be melted without recrystallising the amorphous magnetic material.
