Patent EP-0256701-B1 (EP)
IPC: H04Q3/68
Filed: 1987-07-29
Granted: 1993-09-29
Abstract: An electronics space-division packet switch is disclosed in which each switch crosspoint includes digital logic capable of resolving simultaneous contentions for the source output buss medium. In particular, a bit-by-bit comparison (51) of priority codes disconnects all switches (54) but the one with the highest priority from the output buss (12). This extremely simple crosspoint switch structure makes possible extremely large space-division packet switches in very compact physical form, using large scale integration techniques.

Granted: 1992-09-16
Abstract: A coaxial CO2 laser utilizing high-frequency excitation which has an advantage of the high-frequency excited type that it is small in size and is highly efficient as well as an advantage of the coaxial type that the beam mode has a high quality. The laser has a laser pipe (3) composed of a dielectric and two helical conductors that are adhered onto the outer peripheral surface of the pipe and that have the same pitch. A CO2 laser gas flows through the laser pipe in the axial direction, and a high-frequency voltage is applied across the two conductors from a high-frequency power source (4).

Title: Device for the gas leak testing of hollow structures
IPC: G01M3/32
Filed: 1988-03-10
Granted: 1991-08-07
Abstract: In a method of testing the gas-tightness of walls defining a closed chamber a hollow member of resiliently flexible material is inserted into the chamber. A liquid is introduced into the hollow member until the hollow member substantially fills the chamber. A test gas is then introduced into the space defined between the hollow member and the chamber walls. Escape of any test gas from the chamber is then sensed by loss of gas pressure in the chamber or the presence of test gas outside the chamber. The presence of the liquid-filled hollow member reduces the amount of test gas needed and the associated risks and cost. The chamber may be defined between segments of oil well pipe casing connected by threaded sockets or it may be the space within a tank.

Abstract: Optical-recording medium having a light-transmitting substrate layer. 
<??>CDs are such recording media, on which data are stored in so-called pits, that is to say depressions in a light-reflecting layer following the light-transmitting layer. In the case of magneto-optical discs, data are stored in a magneto-optical layer by magnetising in the one or the other direction of magnetisation. For reading the data stored in this way, use is made of the Kerr effect, which produces a measurable rotation of the polarisation plane when a linearly polarised light beam is reflected at the magneto-optical layer. Although both recording media - CD and magneto-optical disc - already have a high storage capacity, a considerable increase in the storage capacity is of great benefit, in particular for computer applications and as a video disc. 
<??>In order to increase the storage capacity considerably, the light-transmitting substrate layer (1) is followed by a light-reflecting magneto-optical layer (2), in which data can be stored on the one hand by magnetising and on the other hand by means of depressions (3), so-called pits. The light-transmitting substrate layer (1) may also be followed by a partially transmitting magneto-optical layer (2) without pits (3), which is then followed by a light-transmitting layer (10). In this or a following layer (11), data can be stored by means of pits (3). 
<??>Storage medium for computers, video disc, CD.

Title: Device for fixing a ring on a shaft
IPC: F16B21/20
Filed: 1988-12-22
Granted: 1992-07-22
Abstract: A device for fixing a ring on a shaft comprises an annular support having a hole with a laminated tapering section. This section is surrounded by a cylindrical snap ring groove in which a split taper socket with an inversely conical hole is inserted. When the preassembled arrangement of support, ring and split taper socket are pushed on, the conical section of the hole in the support expands, thereby eliminating the wedge-shaped annular gap formed between the hole in the split taper socket and the inner circumference of the annular groove. The device protects the ring from potentially destructive radial forces.

Abstract: When an adaptation request arrives in the form of an adjustment to a manipulated variable or a set point, the resultant settling processes of manipulated variable and controlled variable are sensed and stored. The manipulated variables are supplied to a model (MD), the parameters T,n of which are modified in such a manner that the simulated response of the model excited with the stored variation of the manipulated variable corresponds as closely as possible to the stored real process response. The parameters of a controller (RG) are corrected, for example in accordance with the principle of the optimum of the absolute value, on the basis of the model which has thus been approximated to the process.

Abstract: An amplification procedure is performed on a first sample in which one or more of the four normal ribonucleoside triphosphates(rNTPs) or deoxyribonucleoside triphosphates (dNTPs) is replaced with an exo-sample nucleotide that is not present in nucleic acid to be amplified. After amplification, any contaminating amplified product that may be remaining is subjected to a physical, chemical, enzymatic, or biological treatment which renders nucleic acid containing the exo-sample nucleotide substantially unamplifiable. The treatment may be done as a separate step or it may be done in the presence of a second sample containing nucleic acid sequences to be amplified. The amplified nucleic acid sequences derived from the first sample which contaminate the second sample are not further substantially amplified during amplification of nucleic acid sequences of the second sample.

Abstract: The chemical components of lignocellulosic material which have been dissociated by a steam explosion process can be extracted from the mixture of components using a solvent extraction process. The solvents are water, alcohol and a mild caustic in that order, or the alcohol step can be by-passed and only water and caustic are used. The caustic is a stronger solvent and it will extract the alcohol solubles along with the caustic only solubles. The eluant from the these extractions contains a range of lignin derived substances, which have different applications, such as thermoplastic and thermosetting characteristics. This invention describes a method for partitioning these lignin components into reproducible fractions having definable characteristics for particular applications. For instance, many copolymer applications require a thermosetting only fraction of the lignin. Other applications require a thermoplastic only lignin. The patent also describes a process for converting the thermoplastic lignin fraction to thermosetting lignin. <IMAGE>
