Patent DE-4122741-A1 (DE)
Inventor: AHLBORN GUENTER
IPC: B61F5/16
Filed: 1991-07-10
Abstract: A bogie or truck for high-speed rail vehicles or railway cars includes an H-shaped bogie or truck frame, primary springs cushioning the bogie frame, and a lateral bolster being movable relative to the bogie frame, receiving a coach or car body and being cushioned relative to the bogie or truck frame by air springs. The object is to provide a bogie with a low number of contact points with the coach body, which allows a configuration for rotational retardation, which has a minimum structural width and low weight, which permits small air spring bellows, which allows the installation of additional air reservoirs for the air springs below the lateral bolster and which has additional assemblies disposed at locations which keep the bearing components free from bending or torsional stresses. According to the invention, each air spring is supported directly on the side wall of the bogie frame. The lateral bolster carries friction plates on its upper surface near its transverse ends above its bearing on the air spring for supporting the coach body. The lateral bolster is movable relative to the bogie frame only vertically and horizontally transversely within a defined path and is guided horizontally in the longitudinal direction with play in guides of the bogie frame. The lateral bolster is connected to the coach body through a journal which transmits only horizontal forces, and can be freely rotated with the bogie frame relative to the coach body.

IPC: C07K14/415
Filed: 1991-10-10
Abstract: In the method described, a protein-containing substance is first taken up in an alkaline solvent to give a solution. Insoluble constituents of the substance are separated off, the solution is neutralized and desalinated, and then the proteins contained in the solution are concentrated. The decomposition of the protein-containing substance is carried out at room temperature using homogenization equipment. The heat dissipated into the protein-containing substance during homogenization is simultaneously removed. The pH of the alkaline solvent during the decomposition is over 11.5 and/or decomposition is carried out in the presence of a detergent, in particular sodium dodecyl sulphate (SDS).

Title: Spinning machine with reduced loss of fibre - has double apron drafting with suction roller at output
Inventor: ARTZT PETER
IPC: D01H5/74
Filed: 1991-11-28
Abstract: A spinning machine has a double apron drafting zone with output through a roller pair having another double apron running at the same speed. The bottom apron runs around the two bottom rollers of the output, and the top final roller has a ring form suction to the yarn. The input roller pair leads to a double apron pair and output. The output bottom roller is driven at the same speed as the roller which is surrounded by the apron working in conjunction with the top apron. The top roller is hollow, and has holes in a line around the circumference, to coincide with the section over an arc of 60 deg. in the baffle. An adaptor fits into the centre of this roller to provide the necessary airflow. The sector is formed as a hollow disc, which runs in a groove round the inside of the cylindrical part of the roller, and this forms a seal for the suction. ADVANTAGE - The system reduces hairiness, avoids loss of fibre, creates fewer breaks and improves the quality of the yarn, along with a high draft

Title: Electromagnetic travelling field for physiological tissue stimulation - using travelling DC field of variable intensity and orientation pulse-timed to be synchronised with natural body rhythms.
Inventor: KASTL HEINER
IPC: A61N2/02
Filed: 1992-02-19
Abstract: The method of activating the transport of fluid or ionic substances in human or animal tissue e.g. the lymphatic, muscular or nervous systems, employs a travelling magnetic field of 0.6 to 6000 GAUSS generated by an array of DC supplied electromagnets successively switched by an electronic controller. The activating current pulses have a repetition rate of 0.1 to 10Hz or can coincide with pulse or encephalographic characteristics to promote a peristaltic movement within the tissue. The low voltage source (1,2) supplies the magnets (9 to 16) which are enclosed by a plastic sheet via the capacitors (4), pulse-shaping amplifiers (5 to 8) and pulse timing terminal (3). USE/ADVANTAGE - Stimulates physiological changes in tissue or bone structures to enhance analysis and treatment of defects.

Patent DE-4209744-A1 (DE)
Inventor: SATO MOTOHARU
IPC: G11B5/84
Filed: 1992-03-25
Abstract: A magnetic disk which has a high coercive force having a protective layer formed with a nondiffusive element, not diffusing into a magnetic layer of a Co alloy in a heating process is produced by forming the magnetic layer of a Co alloy and the protective layer in order on a substrate and heat-processing said substrate at a temperature higher than 250 DEG C. An under layer of Cr may be applied prior to the magnetic layer. Numerous examples of the nondiffusive element are specified, eg Zr, and it can comprise two different elements. For example the Zr layer is changed to an oxide layer, etc. by the heating process and becomes a layer which functions as a protective layer, and on the other hand, a chemical compound of Zr and a non-magnetic element in the magnetic layer of a Co alloy, Cr for example, is not generated, so that the segregation of Cr into the crystalline grain boundaries of the magnetic layer of a Co alloy is more effectively expedited. Because of this, since magnetic interactions between the crystalline grains in the magnetic layer of a Co alloy are weakened and disks having high coercive force can be obtained.

Title: Clamp for rope end for use with wind-surfer - has movable part rotating around rotary point in relation to fixed part to clamp firmly rope end
Inventor: NAUJOKS UDO
IPC: B63B35/79
Filed: 1992-09-08
Abstract: A movable part rotates around a pivot point in relation to a fixed part (5) and clamps the rope end tightly. The fixed part is cylindrical and is a shaft of a forked pair of shafts of a wind surf rig. The movable part is displaceable on the fixed part when there is no pull on the rope end (6). The clamp displacement is rendered difficult by a spring arrangement, so that the movable part does not automatically move when there is no pull on the rope end. The clamp effect occurs only by pulling on the rope end vertically to the fixed part and is removed by pulling on the rope end parallel to the fixed part. USE/ADVANTAGE - Used as a safety trapeze fixture for a wind-surfer. Provides an easily adjustable rope end fixture which also incorporates an emergency release facility.

Title: Rapid adaptation of thermal fixer to wider sheet in copier or printer - using lateral position sensor to control motor adjusting relative tension of two roller contact pressure springs before feeding of sheet
Inventor: KOPP WALTER DIPL ING
IPC: G03G15/20
Filed: 1992-10-22
Abstract: In the course of printing or copying onto narrow record carriers, only a portion of the pressure roller (205) and of the fixing roller (201) comes into contact with the carrier, so that unequal heating of both rollers leads to variations in dia. along their length. To overcome this, before a wider record carrier is fed the two rollers are pressed together without any sheet being interposed. The contact pressure is higher over the length of rollers which was in contact with the narrower record carrier. ADVANTAGE - Damage to record carrier and degradation of fixing quality after increase in its width are prevented.
