Title: Process system for continuously measuring the oil content of water
Inventor: EICHHORN BERND
IPC: G01N33/18
Filed: 1983-02-18
Abstract: In a process system for continuously measuring the oil content of water, in which a solvent and sample water is fed by two metering pumps, the oil is extracted from the sample water flow with an organic solvent, the water is removed in a filter, in particular a hydrophobic filter, the oil-laden solvent is analysed in an analyser, in particular an analyser functioning as an infrared measuring instrument, the solvent is subsequently separated from the oil and circulated for reuse and the water removed is drained via a purification stage, a precise measurement is achieved, even after prolonged maintenance-free intervals and even independently of varying metering ratios and quantities, by feeding the solvent and the sample water together through a valve having a spring-loaded valve body and a valve seat which forms a constriction, and from there directly to the filter.

Title: Embossing machine
Inventor: BLANKENBURG HEINZ
IPC: G05B19/23
Filed: 1983-02-19
Abstract: An embossing machine for different sequences of characters has a number of coaxial character discs which can be connected to a common motor via an electronically controlled coupling in each case, it being possible for the individual couplings to be activated in each case via a control device to vary the character adjustment until the character discs have reached their respective intended position, and each individual character disc being assigned a scanning means which serves for determining a starting position for each character disc. Whilst dispensing with further scanning means assigned in each case to the character discs and determining their position, only one common scanning device is provided for direct or indirect scanning of the rotary movement of the common drive side of the couplings, switching means being provided in each case in the control devices assigned to each character disc, which switching means switch output pulses of the scanning device, in each case only after the relevant character disc has been found to have reached the starting position, to the associated control device which controls the respective coupling.

Title: Cleaning of hollow fibres with an aqueous solution
Inventor: SIGDELL JAN-ERIK DR
IPC: B01D65/02
Filed: 1983-07-07
Abstract: The present invention relates to cleaning of hollow fibres in the preparation or re-use of dialysers for artificial kidneys or similar blood filters. In the preparation of such filters it is usually necessary to remove an oily substance by rinsing the hollow fibres and to free them from blood in the processing for re-use. In the preparation it has hitherto been customary to use non-aqueous liquids for rinsing because aqueous solutions in principle lead to shrinkage during the subsequent drying step. The invention describes a process for preventing shrinkage. As a result, the rinsing process is also suitable for processing for re-use because the filter can subsequently be dried and, for example, sterilised with gas.

Title: Joint connection for the extremities of a toy figure
Inventor: JUNGINGER JOERG
IPC: A63H3/46
Filed: 1983-10-25
Abstract: In order to connect the arms and legs of a toy figure with a soft outer coating, for example of material, to the body, a cardboard disc has previously been arranged in each of the parts, the cardboard discs in the adjacent parts then being rotatably fixed to each other by means of metal bolt or the like. Since these known joint connections can become loose during washing and cause rust spots, the object of the present invention is to provide a joint connection which is both washable and, nevertheless, soft in order not to impair the fit of the coating. To this end, the discs (2, 3) of the joint connection (1) consists of plastic, are convex on their outer edge and can be connected to each other by a plastic bolt. The plastic is insensitive to moisture and also causes no rust spots at all, and hard edges are avoided by the convexity of the edge. <IMAGE>

Title: Control key with rotating drive
Inventor: BENESCH HELMUT
IPC: H01H11/00
Filed: 1984-04-04
Abstract: The control key converts a pivoting movement of the handle (5) into a straight-lined movement of the pressure piece (3) by means of a curve and a cam (10) which interacts therewith. The hollow-cylindrical pressure piece (3) has two curves (11, 13) on the radius, one curve (11) of which has a latching depression. When the cam (10) interacts with this curve (11), the control key latches in the limit position. After twisting the pressure piece (3) through 180 DEG , the second curve (13) interacts with the cam (10). This curve has no latching depression. The handle (5) pivots back into the original position after being operated, because of the spring force of the compression spring (4). <IMAGE>
