Patent DE-4020229-A1 (DE)
Inventor: HECK ALFRED
IPC: C22B1/00
Filed: 1990-06-26
Abstract: A device with which grinding residues, that is swarf which is produced in the working of ferromagnetic materials, can be treated is described. Grinding residues of this type are still associated, in particular, with oil and water and are, in this device, placed in a separating tank (14) which contains a detergent substance or washing solution (51). The oil adhering to the grinding residues is dissolved in this separating tank (14) by mixing and stirring. Subsequently, in a first phase, permanent magnets (17) are used to generate on the tank walls magnetic fields in which the ferromagnetic constituents attach themselves to the residues. 
<??>The further constituents can now be passed through a filter (18) and there filtered out of the washing solution. After these constituents have been removed, the magnetic field is switched off. The ferromagnetic constituents are now returned to the washing solution and are passed with the washing solution into this filter (18) or another filter (19), there filtered out and dried. The washing solution is subsequently passed to a tank (25); recovery of the oil removed from the residues takes place in the latter.

Title: Optical sensor row with multiple photo-elements on same substrate - supplies each two-pole photo-element with nonlinear current-voltage characteristic and converts photo-current dynamic range
Inventor: MADER GERHARD DIPL PHYS DR
IPC: H04N5/355
Filed: 1990-09-24
Abstract: The optical sensor row consists of a separated amorphous photoelectric material with a number of photoelements on a substrate (4). Each photoelement (1) is connected to a passive two-pole element (2) of amorphous material with a non-linear current-voltage characteristic on the same substrate.

Title: Gene comparison by restriction length analysis - using fluorescent labels, used to diagnose genetic defects
Inventor: KAMBARA HIDEKI
IPC: C12Q1/68
Filed: 1991-01-07
Abstract: Comparison of genes is effected by (a) cleaving two or more genes with the same enzyme; (b) labelling the DNA fragments from each gene with a different fluorescent label; (c) mixing all the labelled fragments; (d) further cleaving the fragments in the mixt. with an enzyme; (e) separating the fragments; and (f) optically detecting any differences in the pattern of sepd.  fragments. Pref., step (e) is effected by one- or multi-dimensional gel electrophoresis.

Title: Door lock with add-on solenoid operated catch - uses sensors to monitor door operation and also key operation
Inventor: GRECKSCH ERNST DR
IPC: E05B17/22
Filed: 1991-01-31
Abstract: The mechanical lock is in one housing (3) while the add-on solenoid catch (4.1) is in a separate housing (4). Sensors (S1, S2) monitor the opening and closing of the door and operate the solenoid catch accordingly, after a preset time interval. Other sensors (S3, S4) monitor the action of the key operated lock and provide a further control of the solenoid catch. The solenoid catch is only withdrawn if the lock mechanism is opened. It remains locked if the key catch (3, 2) is forced back, without the key operation. The add-on catch has an integral power supply (4, 4). To conserve battery life a switch-off control immobilises the solenoid if the lock is left for long periods e.g. holidays. ADVANTAGE - Simple add-on catch, failsafe operation.

Inventor: MAISCHNER DORA DIPL ING
IPC: B23K26/02
Filed: 1991-02-26
Abstract: In a process for machining workpieces using a laser beam, the machining operation, in particular the welding depth or the degree of through welding, is monitored by detection of optical and/or acoustic signals from a non-protective, laser-induced plasma or steam. To obtain reliable monitoring results as independent as possible of signal fluctuations, the signals undergo frequency analysis and the mean amplitudes (Ax, Ay) of two different frequency bands (x, y) of the analysed frequencies are used, together with a predetermined computational function, to determine a rating value (B).

Title: Thermoplastic material and fabric bonding - by heating plastic across width by pressure against heated plate followed by pressure on applied fabric
Inventor: HEERTEN GEORG DR
IPC: B29D28/00
Filed: 1991-11-23
Abstract: To achieve a firm bond between a wide thermoplastic material surface and an equally wide textile material, the operation is in cycles where, in the first step, part of the thermoplastic material is heated across its whole width by pressure against a heated plate. In a second step, the heated thermoplastic, is bonded with an overlaid textile material through pressure over the whole width.

Title: New nucleic acid sequencing method - using one labelled nucleotide at one time in cycles comprising elongation, wash, label detection and removal of the label, then repeating
Inventor: ANSORGE WILHELM DR
IPC: C12Q1/6869
Filed: 1991-12-13
Abstract: Claimed is a nucleic acid (NA) sequencing method in which a double strand of an at least partially single stranded template NA is synthesised starting from a double stranded NA piece or a primer by (i) incubation of the NA with a DNA elongation mixt. including a polymerase and one of the four nucleotides which is labelled, (ii) sepg. the NA from the elongation mixt., (iii) detection of any labelled nucleotide insertions, (iv) removal of the label if there had been an insertion, and repeating (i)-(iv) for all four nucleotides separately. Pref., the NA is anchored to a fixed phase such as biotin/avidin. USE/ADVANTAGE - Very long NAs and small amts. of NAs can be detected with a high accuracy since each DNA mol. contributes to the labelling. The limited capacity of gel matrixes is overcome so that any length of NA can be sequenced. Even if a wrong nucleotide had been incorporated the wrong signal is removed so that it does not influence further sequencing.
