Title: Purifying electrolytic copper@ refining solution
Inventor: TOMITA MASATOSHI
IPC: C25C1/12
Filed: 1997-03-13
Abstract: A process for purifying a sulphuric acid-containing electrolytic copper solution, circulating in an electrolytic copper refining system, involves adding sodium hydrogen sulphide to a withdrawn portion of the solution for in-situ production of only the requisite quantity of hydrogen sulphide gas which is used for the purification treatment. Also claimed are: (1) a similar process in which (a) the withdrawn solution is split into two portions; (b) the first portion is treated with sodium hydrogen sulphide to precipitate and remove metals (e.g. Cu, As, Sb and Bi) as sulphides and is then treated with excess sodium hydrogen sulphide for reaction with residual sulphuric acid to produce hydrogen sulphide gas; (c) the hydrogen sulphide gas is used for treating the second portion of the solution to precipitate and remove metals (e.g. Cu, As, Sb and Bi) as sulphides; and (d) the filtrate from the second portion of the solution is returned to the electrolytic refining system; and (2) a similar process in which (a') the solution is contacted with hydrogen sulphide gas to precipitate and remove Cu, As, Sb and Bi as sulphides; (b') the solution is split into two portions; (c') the first portion is returned to the electrolytic refining system; and (d') the second portion is treated with excess sodium hydrogen sulphide to separate and recover Ni as the sulphide, the resulting hydrogen sulphide gas being used in step (a').
Patent DE-19712107-A1 (DE)
Inventor: POLZ HANS DR
IPC: A61B5/352
Filed: 1997-03-22
Abstract: The method involves transforming raw data into a data set to produce a corresponding image or grey-scale value for each voxel according to a defined algorithm. The image or grey-scale value is used for that image point which does not exceed a maximum permissible distance from the nearest voxel in the individual image or image plane. Each voxel or its position is selected for the transformation according to a defined program routine. Finally, the image or grey-scale value is formed for the voxel, whereby the maximum permissible distance can be fixed or adjustable.

Patent DE-19733906-A1 (DE)
Inventor: LORENZ JOACHIM DIPL ING
IPC: H04L12/403
Filed: 1997-08-05
Abstract: The invention relates to a method for automatic address allocation, said method being based on distance measurement. According to the invention, a master (M) transmits a preamble (P) via the bus. Said preamble is received by all slaves that are to be addressed. The slaves react to the preamble (P) by transmitting a sequence of response signals (A). A slave (S2) located in the direction of the master (M) upstream from a slave (S3) transmitting a sequence of response signals (A) records the sequence of response signals (A) from the transmitting slave (S3) and waits for a new preamble (P). The slave (Sz) which does not record any sequences of response signals (A) from other slaves is the last slave when seen from the master (M) without an address allocation on the bus. Said slave (Sz) becomes available to receive a telegram (T) from the master(M) giving it a name. During the next cycle of the method the slave (Sz) which has recently been given a name no longer reacts to the preamble (P) enabling another slave which evaluates the bus constellation to become available for reception of the telegram giving it a name. In this way all slaves without an address are gradually given a name.

Patent DE-19811516-A1 (DE)
Title: Card-matching magazine shaft with bottom end stop
IPC: B65H3/24
Filed: 1998-03-17
Abstract: An opening (26) below the card (14) shaft (28) end stop (32) extends the shaft in a contour matching that of the card, but offset slightly from the shaft, so the edge of the opening acts as end stop. The opening reaches into the shaft section and plunger (44) level with the surface supporting the bottom card, and it moves parallel to the card plane with the result that the card is tilted over across the shaft section and so fits into the outline of the extension opening. The bottom end of the shaft (24) and the opening are enclosed in frame structure (20,22), whose two parts are joined together to hold respective end stop surfaces a few degrees apart round the shaft axis. The frame is recessed (47,48) opposite the end stop surface to one card height, so the vertical side of this recess (58) is in line with the edges of the opening below. Plungers are arranged on longitudinal sides of the shaft close to the bottom end for the card tilting operation.

Title: Fire fighting nitrogen generator for closed room oxygen concentration reduction, to halt combustion
Inventor: WAGNER ERNST WERNER
IPC: A62C2/00
Filed: 1998-03-18
Abstract: A nitrogen generator (as opposed to bottled gas) is used to reduce the oxygen concentration from the normal 21% to about 16% so that the room could still be visited safely. In case of fire this concentration is lowered to about 12% by using bottled gas and at this level combustion cannot be sustained.  Oxygen concentration is monitored by instruments incorporated in an aspirating type of fire detector/alarm so that the operation of this system is automatic. T here can be provision to lower the oxygen concentration at night, when it is unlikely that the room need be visited, from the stated 16% by using the nitrogen generator.
