Title: Bulk grain silo hatch hinge and closing mechanism
Inventor: IMMEL BERTHOLD
IPC: B65D90/32
Filed: 1996-03-05
Abstract: A hatch closes a bulk solids storage silo with contents stored under pressure or representing a risk of fire or explosion. The hatch opens to one side on a hinge mechanism which raises it clear of the curved silo wall. In the closed position, the edge of the hatch is sealed against the silo, and the closing mechanism exerts a continual pre-determined closing force on the hatch. If a given closing pressure threshold is exceeded, the pressure on the hatch is temporarily relaxed. The closing assembly (6) has a locking assembly (17) linked to the closing element (7). When the hatch (2) starts to open the closing element pushes against and releases the hatch. It does not permit the closing element to swing back to the locked position until the closing hatch has almost reached the closed position.

Patent DE-19623203-A1 (DE)
Inventor: STRAUSS MICHAEL PROF DR
IPC: C12N9/00
Filed: 1996-06-11
Abstract: A virus vector is disclosed for the transfer of stable episomes, i.e. extrachromosomal genetic elements. The invention has applications in medicine, in particular genetic therapy, and in medical-biological fundamental research. The object of the invention is to prolong by autonomous replication the function of a gene, which normally subsists only for a short time after viral gene transfer, and at the same time to effectively inhibit the expression of viral genes. The aim of the invention is to introduce by means of a virus into target cells a DNA whose replication cycle matches the cycle of said cells and which is introduced during nuclear division into the nucleus of the daughter cells. For this purpose, the disclosed virus vector for the transfer of stable episomes has a virus DNA, a DNA sequence that is autonomously replicable and into which the gene to be transferred is incorporated, at least 2 recognition sites for a specific recombinase, and if required a specific recombinase gene incorporated into the virus DNA.

Patent DE-19702321-A1 (DE)
Title: Adaptive filtering of sample series
Inventor: KRAKER ALFRED DIPL ING
IPC: H03H21/00
Filed: 1997-01-23
Abstract: The method involves an adaptive filtering of an input sequence of sample values of a signal. An error value is formed from a respective output value and a corresponding reference value, as a measure for the deviation between those values. New coefficients for a respective next filter step are calculated from a filter coefficient of a current filter step.  The inverse of a correlation matrix is used when calculating the new coefficients, which indicates, through its elements, the correlation between the sample values of the input vectors of a section in the respectively preceding filter step. A new inverse of a new correlation matrix is calculated from the inverse for the coefficient determination in the respectively next filter step. The section has a constant length during at least two successive filter steps.

Title: Vacuum cleaner extension head pivotally joined to the main suction body with a working position angle and a parking position
Inventor: SINSTEDTEN JOHANNES
IPC: A47L9/02
Filed: 1997-05-02
Abstract: The vacuum cleaner suction unit and handle has two bistable positions by which it is stored when not in use with the unit upright and when used may be lowered to reach beneath furniture. A spring-tensioned wire is attached to one end of a link on the pivoting mechanism and is shortest at the two preferred positions. The pivoting mechanism (4) in the extension head (3) has a wire (7) attached to a lever (5), which moves with the suction body about an axis x, and a tension spring (6) attached to a fixed point (9). In the lowest position of the cleaner (2) the wire is tensioned least and the head unit is lowered at the far end (16), increasing suction there. As the cleaner handle is raised the tension in the wire increases and suction is equalised. When the handle is in the upright position for storage the lever (8) is held towards the end (16) of the head. Tension is adjustable by means of a manually operated lever (14) which deflects the wire between control points (10,11).

Title: Cellulose filament yarn production
Inventor: MICHELS CHRISTOPH DR
IPC: D01D5/06
Filed: 1997-10-08
Abstract: The precipitation bath is used for the production of cellulose filament yarns, in a dry-wet extrusion process. The precipitation bath has a laminar upwards flow in the zone surrounding the spinning funnel. The main portion of the precipitation bath flows in on the entry cross-section of the spinning funnel in a zone which is 3-20 mm below the bath surface level and, after contact with the filaments along a stretch of 30-130 mm, it is partially separated from the filaments. Surplus precipitation bath liquid passes out of the spinning funnel zone through an overflow. The overflow and the separated main portion of the fluid is returned to the zone round the spinning funnel. In an Independent claim the apparatus has a spinning funnel (2) with a total length (SL) of 30-100 mm. The ratio of the funnel entry and outlet cross-sections A1:A2 is 5:1 to 80:1. A feed opening (4) is at the base of the spinning box (1), and an overflow barrier (5) for the precipitation bath (3) is at a level of 5-15 mm over the upper edge of the spinning funnel. Preferred Features:- The precipitation bath liquid, before entry into the zone round the spinning funnel, has a flow speed which is faster through a filled body stretch than in an empty stretch, with the flows aligned vertically upwards and downwards. The liquid flow speed is accelerated by 5-80 times in the spinning funnel. On leaving the spinning funnel, the filaments are deflected at a tangent or at a small angle of up to 30 deg , out of the precipitation bath liquid flow. The length (SL) of the spinning funnel (2) is pref. 40-60 mm, and the funnel entry-outlet ratio A1:A2 is pref. 10:1 to 30:1. A flow channel (14) is in front of the feed opening (4), with a section filled with bodies (20) and an empty section (21) at the outflow side. A lower container (10) holds the precipitation bath overflow from the spinning funnel (2) and the spinning box (1), and is connected to the feed opening (4) through a pump (17). The air gap (SV), between the spinning jet (6) and the surface of the spinning bath, has a width of 10-50 mm. The spinning funnel (2) is of an elastic material.
