Patent DE-3824051-C1 (DE)
Title: Wire-grid weaving machine for pressed wires with automatic weft insertion
IPC: D03D41/00
Filed: 1988-07-15
Granted: 1989-07-27
Abstract: In the hitherto known grid-weaving machines for pressed wires, it has not been possible to determine an exact position of the crimpings in relation to the warp wires, so that fault additions can occur here during the cutting-off operation, with the result that, as the case may be, corresponding weft wires are not tied in correctly. In order to guarantee an exact weft insertion, there is proposed a light-(? not sure of word) arrangement which senses the crimping of the weft wire and which controls the draw-in rolls of the roller insertion assembly accordingly.

Title: Safety device for an electrochemical cell and method
IPC: H01M50/569
Filed: 1988-08-03
Granted: 1990-03-01
Abstract: The invention relates to a safety device for an electrochemical cell and a method for implementing this safety device. The intention in this case is to permit a response which is sufficiently fast for breaking of the cell (1) or the like to be prevented, even in the event of internal short-circuits. The problem is solved by providing at least one drain valve in the cell (1) and by providing a removal device, preferably in the form of an inert gas contained under pressure in a vessel (4), which gas penetrates quickly into the cell (1) or the like via a line and removes the electrolyte so that no further chemical reaction is possible. Advantageously, the cell (1) or the like is linked via a valve to an electrolyte circuit, the electrolyte circuit being interrupted in the event of malfunction and connection with the inert gas being set up instead. <IMAGE>

Title: Component for covering the space surrounding the saw blade of a jigsaw
IPC: B23D49/16
Filed: 1988-12-08
Granted: 1989-12-21
Abstract: In order to effectively extract the accumulating sawdust or chips in hand-guided jigsaws, it is known to cover the saw blade and the space surrounding it by a u-shaped hood sitting on the sole plate of the jigsaw. However, this hood does not permit any bevel cuts, since it prevents swivelling of the sole plate relative to the jigsaw. The novel component is also intended to enable bevel cuts to be made without impairing the suction action. The component is provided with vertically adjustable wall parts (18, 19) relative to the plane of the sole plate (24) of the jigsaw. The wall parts (18, 19) are carried along with the sole plate when the latter is swung out. <IMAGE>

IPC: A47C9/10
Filed: 1990-02-16
Granted: 1991-05-08
Abstract: The folding stool has scissor-type pairs of legs (1,2) which can be telescopically shortened to about one half of their length.  The top ends of the legs are joined by two struts (11).

The top ends of the legs are linked to the seat struts and fixed to one shank of an L-shaped angled link (9,10) so that they can move through 270 deg. on axes (27,28).  The connecting struts have locking bolts and holes. ADVANTAGE - Load relief for the link bolts, easy handling, and improved stability.

Granted: 1991-07-25
Abstract: A frame (3) of a form panel (1) is formed by a hollow profile (4), preferably having a closed cross-section, the cross-section of this hollow profile (4) corresponding substantially approximately to a rectangle. Provided adjacent to the outermost edge web (5) of this hollow profile (4) but without affecting the length or width of this edge web (5), on a profile section or end web (9) running transversely to this edge web (5), is at least one recess (7), to which a crowbar (8) can be attached when the edge web (5) is standing on a ground surface (6) or the like. The edge web (5) can thus have its greatest possible width on the hollow profile (4) despite such a recess (7) serving for the engagement of a crowbar (8) and is protected in the best possible way against deformations by the crowbar (8), so that it remains a substantially level and undeformed stop for a neighbouring shuttering element even after prolonged use.

Title: Process and apparatus for removing acid, iron and manganese from water
Inventor: SCHULER HANSJOERG DIPL ING
IPC: C02F1/64
Filed: 1993-04-27
Granted: 1994-11-03
Abstract: A process for removing acid from (deacidification of) water or elevating the pH and hardening water, in particular for treatment to give drinking water in an in-house water supply, based on a filtration of the water to be treated via a bed containing a lime filter material, is characterised in that a removal of iron and/or removal of manganese from the water to be treated is performed in the same apparatus and simultaneously with the deacidification or pH elevation and hardening, and in that instead of periodic backwashing the filter material, after it is exhausted, is discarded, where exhausted denotes that the filter material has decomposed, is no longer to be used for hygienic reasons and/or is blocked with precipitated iron and manganese reaction products. The process is inexpensive and backwashing the water treatment unit is not necessary. <IMAGE>
