Patent DE-3610940-A1 (DE)
Inventor: MATZKE WOLFGANG DR ING
IPC: D21B1/16
Filed: 1986-04-02
Abstract: The bleaching chemicals are added to the pulp immediately after heating of the raw pulp thickened to more than 20% by weight and immediately prior to a dispersing process. This is carried out in a high-speed, high-efficiency disperser, where the heated, thickened pulp is forced through a plurality of narrow slits in a disperser lining and is exposed to strong shearing, impact and kneading stresses. In this way, the dispersing process is reduced to a time period less than 3 seconds, preferably about 1 second or less. As a result, the total time required for reductive bleaching is reduced to less than 15 seconds and no further measures are required for displacing and excluding air from the system. The method can also be advantageously used with oxidative bleaching at reduced reaction time requirements. A high dispersing temperature in the region of 40 DEG C. to 110 DEG  C., preferably about 95 DEG  C. is possible and there are essentially simultaneously carried out the bleaching and dispersing actions without the need for separate dispersing stages and large reaction towers and pumps.

Title: Apparatus with step-shaped, vertically offset access levels
Inventor: THEIS RICHARD
IPC: A63H18/02
Filed: 1986-04-11
Abstract: The invention "apparatus with step-shaped, vertically offset access levels" makes it possible for a motor vehicle to gain access from a 1st driveway level onto a 2nd, higher, central driveway level, and from there onto a 3rd driveway level which is, once again, higher or at a distance from the 2nd level. The arrangement, according to the invention, of the access ramps or levels is to make it possible, only with special driving knowhow and only during a defined period of time, for the vehicle to move onto the 3rd driveway level, this being possible only utilising the mass inertia of the vehicle. In this arrangement, there is effected a gradually increasing pivoting of the vehicle in the direction of the higher driveway level and, finally, an actuation of the drive or of the brakes of the vehicle. According to the invention, for gaining access from the 1st driveway level to the central driveway level, the apparatus has between these levels, at least laterally in the drive path, in each case one access support or a slope. This merges flush into a stretch in the central, horizontal driveway level, said stretch or level being formed by the rocker board, located in its rest position, of a rocker stand. The rocker board is articulated beneath the rocker axis, with its board longitudinal direction perpendicular thereto, such that it swings tangentially about a circumferential circle with respect to the rocker axis and, finally, strikes laterally against a horizontal, spaced-apart ramp of the 3rd, higher driveway level.

Title: Underwater mine projectile with adjustable detonation system - penetrates vessel hull or detonates above surface level
Inventor: SIEBERT RAINER
IPC: F42C15/32
Filed: 1986-07-19
Abstract: The projectile launcher (14) is located on the seabed (12) and is activated by surface vessel sound waves (16) which, via a sensor (15), ignite the projectile motor unit (21).  Immediately after launch, a drag line (25,26) is deployed which stabilises the projectile (11) and exerts a hold off pressure on the warhead ignitor (24).  As the end of the drag line leaves the surface (18) or penetrates the vessels hull (19) water pressure on the drag line decreases immediately, allowing the igniter (24) to arm and detonate the warhead (27).  A length (x) of the drag line is set to allow sufficient hull (19) penetration (x), or height (x) above the surface (18), before detonation occurs. USE/ADVANTAGE - Simple non-electronic activated warhead igniter. Detonation point can be pre-set by drag length.

Inventor: HEHL KARL
IPC: B29C45/17
Filed: 1986-08-05
Abstract: The mould exchanging apparatus, serving a plurality of plastic injection moulding machines, comprises an exchanging table (27), which serves as transporting carriage and can be moved in a linear guide (45) to a depot (44) for injection moulds as well as to the plastic injection moulding machines, aligned in parallel with the guide (45), in connecting position for the mould change. Two mould receiving places are arranged one behind the other on a rotatable carrier plate (27h) on the exchanging table (27). In the connecting positions, mould guides (G") of the receiving places, with the carrier plate (27b) turned if need be, form alternately with a mould guide of the mould clamping space of a plastic injection moulding machine and alternately with a mould guide of a depot receiving place (44a) transport tracks for the exchanging of an injection mould. It is achieved by such a design that the injection moulds of an entire group of plastic injection moulding machines can be exchanged fully automatically with the exchanging table (27), provided that the said machines are arranged in a space-saving manner with respect to the mould depot (44). This arrangement avoids running over the operator sides of the plastic injection moulding machines, and consequently the operator, following an upright transporter. <IMAGE>

Title: Device for heat-treatment of articles tending to cake
Inventor: STEININGER FRANZ
IPC: F27B7/18
Filed: 1986-12-06
Abstract: The invention relates to the problem of automatically keeping the inner wall of a heated rotary tube (1) free from caking. It is based on the state of the art, in which a rolling body lies in the rotary tube, which body is provided on its outer surface with at least one helical strip. The basic thought of the invention consists in imposing on the rolling body a sliding movement instead of a pure rolling-off movement in order to achieve a scraping action of the strip on the rotary tube wall. To this end, the invention proposes two solutions. The first solution consists in the rolling body (10) being conical. The second solution consists in two cylindrical rolling bodies (17, 18) being present and the strips (19, 20) of the two rolling bodies (17, 18) being designed as counter-running screw windings which engage in one another. <IMAGE>

Title: Arrangement for feeding an extremely low frequency transmission antenna
Inventor: ESPRESTER RALF DR ING
IPC: H04B1/04
Filed: 1986-12-19
Abstract: An essentially known DC-voltage-fed switching transformer is used to activate a transmission antenna in order to radiate extremely low frequencies (ELF) with an AC signal. Thanks to the high efficiency which can thus be achieved, only small cooling units are required. Since the switching transformer is operated with a switching frequency which is significantly higher than the actual transmission frequency, the size of the reactive elements of the arrangement is also minimised. The arrangement according to the invention is therefore especially important for mobile transmitters.

Patent DE-3743193-A1 (DE)
Inventor: SCHMIDT PETER
IPC: A61G7/10
Filed: 1987-12-19
Abstract: A raising plate (14) is supported by two guide arrangements (16) in the form of pivot frames (18, 20) connected to one another in a hinged manner. In the raised position of the plate (14), the pivot frames (18, 20) are so upright that the slide bearings (28, 34) of the pivot frames (18, 20) tend to jam in the rails (30) guiding them. If the raising arrangement is activated so as to effect a lowering movement of the plate (14), the plate (14) would retain its height position on account of the tendency of the slide bearings (28, 34) to jam. This tendency to jam is overcome by virtue of a spring arrangement (36) engaging in the area of the upper pivot bearing (34) of at least one guide arrangement (16). <IMAGE>
