Title: Composite-material panel
Inventor: GALLINA RICHARD
IPC: H01B3/52
Filed: 1994-02-03
Abstract: A description is given of a composite-material panel having a core comprising a plurality of layers of synthetic resin impregnated kraft paper, which is bonded on each of both sides with an outer layer of impregnated covering paper.

Title: Resin-containing, low-remanence composition, and magnetic component produced therefrom in the form of a preform
Inventor: SUZUKI KEIICHIRO
IPC: C08K3/22
Filed: 1994-02-24
Abstract: The invention relates to a resin-containing, low-remanence (low-retentivity, soft-magnetic) composition comprising (a) 80-95% by weight of a pulverulent, low-remanence material and (b) 5-20% by weight of a resin component, where the latter contains (1) 70-99.5% by weight of a polyarylene sulfide resin (2) 0.5-30% by weight of a polyethylene of particularly high molecular weight whose mean molecular weight (weight average) is in the range from 4 x 10<5> to about 7 x 10<6>. As a consequence of the presence of polyethylene of particularly high molecular weight, a magnetic composition having improved flow behaviour in the molten state is provided which is suitable for processing by injection moulding, while at the same time adequate heat resistance during soldering is maintained, as is evident from the fact that a preform made from the composition exhibits no cracking after immersion for about 10 minutes in a solder bath at about 260 DEG C.

Title: Equipping a filter plant with rigid sintered plastic filter elements
IPC: B01D46/24
Filed: 1994-05-24
Abstract: In a procedure for equipping a filter plant (4), at least one of the existing filter bags is removed and replaced by a filter element arrangement consisting of inherently mechanically stable, sintered, open-topped filter elements (18,19) attached to a connection element (16) which fits onto the connection point for the removed filter bag. Also claimed is a filter element arrangement for use in the procedure.  The elements used in the procedure are made from sintered granular plastic materials, and more than one element is attached to a circular connection element. More pref., two filter elements extend longitudinally and side-by-side. The procedure includes the modification of the pipework and nozzles for the reverse-flow cleaning system so that a nozzle (28,30) is directed into the open end of each new element.  The elements are fixed to the connection pieces using a plastic moulding material. The cross-section of the elements perpendicular to the longitudinal axis is such as to fit within a circle of 100-200 mm diameter. The ratio of length to the smallest width of the element is at least 25:1. Where two elements are mounted on a common connection piece, their closed ends are connected by a holder (22).

Title: Non-destructive thickness measurement of semiconductor wafer
Inventor: HABERGER KARL DIPL PHYS
IPC: G01B7/06
Filed: 1994-06-15
Abstract: A method for the non-destructive testing of the thickness of a semiconductor wafer (100) whose first principal surface (102) is brought into contact with a similar and supporting silicon wafer (107) whose contacting surface has a nickel plated layer (106) of high magnetic permeability. The opposite surface (104) of the wafer (100) under test carries a flat pick-up coil (108) whose inductance varies inversely with its separation from the nickel layer (106) and is therefore a measure of the wafer (100) thickness. The coil (108) forms an element of an oscillator circuit whose frequency changes can be readily correlated with the wafer (100) thickness with considerable accuracy.
Patent DE-4421784-A1 (DE)
Inventor: FLECKENSTEIN THEO DR
IPC: C11D7/44
Filed: 1994-06-22
Abstract: The novel agent is based on powdered cellulose as the adsorbent and also contains a cleaning fluid, water in the simplest case, an colloidal silicon dioxide. The agent is distinguished by its extraordinarily thorough cleaning performance and a very low tendency of the textiles cleaned thereby to become dirty again. The accumulation of residues on the textiles repeatedly treated with this agent is very low. It is also surprising that the textile materials are treated very gently during the cleaning process.

Abstract: Selon l'invention, une batterie de secours constituée par un accumulateur, servant à assurer l'alimentation de secours d'un circuit, en tension de service, est réunie avec un élément irréversible électriquement constitué par un fusible, pour former une unité. Si cet élément irréversible se trouve à son état initial au moment d'une interrogation, il passe à son état irréversible et ce moment est mémorisé. En fixant sans ambiguïté le moment de la première mise en service de la batterie de secours, on peut éviter un échange de la batterie, semblant impératif pour des raisons de sécurité, avant la fin de la durée de vie garantie. Dans un mode de réalisation particulier de l'invention, l'élément irréversible indique le moment où la batterie de secours atteint la fin de sa durée de vie.
