Patent DE-3632226-A1 (DE)
Title: Solubilisation chromatograph
Inventor: KUZE SHUICHI
IPC: B01D15/08
Filed: 1986-09-23
Abstract: In a solubilisation chromatograph, a solvent composed of a buffer solution and ionised micelles is passed through a capillary tube whose two ends are connected to the positive terminal and the negative terminal, respectively, of a direct-current source, then a sample is introduced into the capillary tube. Constituents of the sample introduced are separated by a combination of the phenomenon of the dissolution of the sample in the ionised micelles with a capillary electrophoresis process. A qualitative or a quantitative analysis of the sample constituents is carried out. The chromatograph is characterised in that a three-way connection (10) is connected by means of a first opening to the capillary tube (1) and by means of a second opening to a line (8) for supplying the said solution and the sample, while its third opening, which serves as outlet opening, is disposed on the inlet side of the capillary tube (1) in order to bring the inlet of the latter into contact with a flow of a solution composed of the sample and the solvent and to drain the remaining solution, which has not been introduced into the capillary tube, via the third opening, and furthermore a device for varying a contacting time of the capillary tube with the sample and/or a device for controlling an amount of sample sucked into the capillary tube are provided. <IMAGE>

Title: Method and apparatus for setting uniform treatment-agent coatings on running material webs
Inventor: TISCHBEIN CLAUS DIPL ING
IPC: D06B23/26
Filed: 1986-11-29
Abstract: The invention relates to a method and an apparatus for setting uniform treatment-agent coatings on running material webs, especially on webs of woven and knitted fabric, and is intended by simple means to obtain reliable measurement values for controlling the linear pressure of a squeezing unit, downstream of the coating device, over the width of the material web. For this purpose, it is proposed, according to the invention, before the coating of the treatment agent, to subject the dry material web to throughflow measurements in a manner distributed over the width of the material web and to use the resulting varying throughflow values in order to set the varying linear pressures for squeezing off the coated treatment agent over the width of the material web (Figure 1).   <IMAGE>
Patent DE-3641166-A1 (DE)
Title: Bioherbicide broadcaster and liquid-manure broadcaster
Inventor: KLASEN ANTON
IPC: A01M21/04
Filed: 1986-12-02
Abstract: The sector of use of the bioherbicide broadcaster is agriculture. It is an appliance which works without nozzles. It generates a closed spraying-agent circuit, so that no spraying agent escapes outwards. Functioning is based on the fact that the spraying agent flows out of a tank through a pipe onto a spreading disc which rotates. The arrangement of some steps results in a spreading mist. The broadcast spreading agent is intercepted again by a frame and pumped back into the tank. The appliance is mounted behind a tractor and is set in such a way that the frame sweeps precisely over the entire flora. Now, when the tractor travels over a field or meadow, only the projecting weeds protrude into the spreading mist. In this way, only the stubborn weeds are wetted in a fully controlled manner. The entire remaining environment remains protected from the spraying agent. There is no other spraying method which takes place in such a controlled and such an economical way. After the frame has been removed, an outstanding liquid-manure broadcaster is obtained.
Patent DE-3641264-A1 (DE)
Title: Gas-pressure-sprung ski pole
Inventor: RIENKS GERD
IPC: A63C11/22
Filed: 1986-05-30
Abstract: Conventional ski poles are intended to generate propulsion through arm movements. To this end, an arm posture is necessary in which only slight forces can be transmitted. The angle of the pole and length of stroke are unfavourable. Because of the telescopic pre-stress of the gas-pressure-sprung ski pole, the force of a "pull-up", in other words virtually the entire body weight of the skier, can be stored even in the vertical position. Then, in the oblique position of the ski pole, the stored force is liberated in the form of propulsion in an ergonomically favourable body posture and accelerates the skier very substantially, doing so over a relatively long "length of stroke", which is obtained cumulatively from the spring travel of the pole plus the arm stroke.

Title: Continuously operating melt filter with automatic passage of a filter-fabric band
Inventor: REINHARD MICHAEL DR
IPC: B29C48/692
Filed: 1987-03-31
Abstract: The invention relates to a melt filter for removing contaminants, foreign bodies and agglomerations from plastic melts and other fluids. The object underlying the invention is to provide a melt filter with a through-running filter-fabric band, which operates automatically, that is to say operates for a long period without manual cleaning and exchanging work, also operates without problems in the case of high melt pressures and in the case of melts with low viscosity and a sharp solidification point and in which only low forces have to be transmitted through the band. The object is achieved according to the invention in that the filter-fabric band (1) is guided continuously by means of a rotating carousel (2) through the melt stream (3), in that the forces necessary for transporting the filter-fabric band (1) are transmitted by a combination of frictional and positive connection and in that the sealing of the melt with respect to the exterior is carried out by mechanical means. <IMAGE>

Title: Rewinding device to make used carbon ribbon cartridges for typewriters illegible
Inventor: TRAUT HANSJOERG DR
IPC: B41J35/38
Filed: 1987-10-14
Abstract: As long as "non-deleting" carbon ink-ribbon cartridges are used in typewriters, the rewinding of the carbon ribbons which have been used and are thus also impressed in a non-deletable manner and making them illegible at the same time is the only quickly implementable possibility of complying with the requirements of data protection. This purpose is fulfilled by a rewinding device in the manner of a super-eight film viewer, in which the used ink ribbon is guided over deflection rollers before it is wound up, for example onto a super-eight film reel. When it passes over the deflection rollers, some of the characters are punched out in order to make the stored data illegible. <IMAGE>

Title: Method for producing a superstructure for railways
Inventor: SCHUHBAUER ALBERT DIPL ING DR
IPC: E01B1/00
Filed: 1988-03-29
Abstract: A method is used to produce a superstructure for railways, consisting of slabs laid on the formation, preferably of a jointlessly produced slab of concrete or special concrete with plastic and/or bitumen additives, optionally with an upper levelling layer of fine asphalt concrete. The track grid consisting of tracks screwed to concrete sleepers is bonded to said slabs by means of a bitumen- and/or plastic-based casting compound. In order to provide a superstructure of this type in which the track grid can be readily bonded to the baseplate by the casting compound, in particular also in banked curve regions, parallelepipedal precast concrete parts (4) are inserted into the spaces between the sleepers (2) and bonded to the sleepers (2) and the slab (1) by means of the casting compound (10) (Fig. 2). <IMAGE>
Patent DE-3812219-A1 (DE)
Title: Recompression for CO2 weapons and compressed-air weapons
Inventor: JUENGLING HELMUT
IPC: F41B11/723
Filed: 1988-04-13
Abstract: The recompression is intended for CO2 weapons and all types of compressed-air weapons. It is installed, for example, after the main cylinder (2) (in Figure 1) but can also expediently be integrated in the piston (6) (shown by dashed-dotted lines in Figure 1). The object of recompression is to prevent a vacuum being formed when the air emerges in an explosive manner from the compression chamber (1), and furthermore to minimise the force which is required for compression. The compression acts simply by a piston (14) being forced back by the compressed air onto an opposing spring force of the spring (15) in Figure 1, or (21) in Figure 2. If the recompression is, for example, integrated in the piston (6) (shown by dashed-dotted lines in Figure 1), then the piston and springs (14 and 15) in Figure 1 and (20 and 21) in Figure 2 are omitted. When a shot is fired, the compressed air leaves, for example, the compression chamber (1) in Figure 1, and in this case a valve (10) or a hole (9) in Figure 2 is dimensioned such that the spring pressure (15 on 14) and (21 on 20) which then acts forces the pistons (14 and 20) continuously back to the original point without a weapon being jolted, for example, in the process. <IMAGE>

Patent DE-3833812-A1 (DE)
Title: Energy convertor
IPC: F03D5/00
Filed: 1988-10-05
Abstract: Energy convertor which comprises a container of various shapes, in which balls move in an unordered manner and in which one or more arms are attached. Attached on the arms is a plurality of movable flaps which open about their pivot only in one direction and independently of one another and which allow passage of a ball only in this one direction. The arms are attached in such a manner that every ball which wishes to pass through the arm line collides with one or more flaps. Furthermore, the arms are connected to one or more shafts. The shafts are attached in such a manner that they permit the arms to rotate about them. The container which is set in motion by the effect of energy from outside transfers energy to the balls located in the said container. If a ball wishes to pass the arm line, it collides with one or more flaps. If the collision takes place on the opening side of the flap, the ball passes the arm line unhindered. If the collision takes place on the other side, the flap, which does not open from this side in the present impact direction, prevents the passage of the ball. As a result of the collision, the ball energy is transferred onto the shaft by means of the flap(s) and the arm.
