Title: Process for producing cellulose from lignin-containing raw materials.
Inventor: CALL HANS-PETER
IPC: D21C9/10
Filed: 1987-10-24
Abstract: A process and apparatus for transforming and/or extracting lignin or its decomposition products from lignin-cellulosic materials. For this purpose, a redox potential in the 200-500 mV range is set by adding oxidizing and/or reducing agents and/or salts and/or phenolic compounds to an acid aqueous solution of the lignin-containing raw materials. The lignin-decomposing reaction is initiated with bleaching by adding enzymes, micro-organisms, animal or vegetable cells. The reaction is maintained for several hours at a redox potential value oscillating around a constant value, at a constant temperature and with constant agitation.

Abstract: In a precision operable robot arm comprising four levers (11-14) pivotally connected with each other into a parallel arranged link form, when one ends of first and second levers aligned vertically, for example, are driven respectively by two motors (2, 3) such that the levers are swung around the alignment axis in a horizontal plane, for example, a work supporting device (16) provided at an outwardly extending end of the fourth lever (14) is also moved in a horizontal plane. 
     A first pulley (8) is fixedly secured to a position aligning with the driving shafts (5, 6) of the two motors, while second and third pulleys (17, 18), which are integrally rotatable, are rotatably supported by a pivot pin (15) coupling the second and fourth levers, and fourth pulley (19) rotatably supported at the outer end of the fourth lever is fixed to the work supporting device. First and second belts (21, 22) are extended around the first pulley and the second pulley, and the third pulley and the fourth pulley, respectively, so that the work supporting device is held in the same posture regardless of the movement thereof int he plane.

Abstract: The invention relates to a modified beeswax and to a process for this modification. The modification consists of a treatment of beeswax to remove free acids. According to the invention this can be accomplished by reacting the free acid present in beeswax with glycidol at a temperature of 80 to 120°C in the presence of a basic catalyst. This modification results in an improvement of the properties of the beeswax. The modified beeswax being outstandingly suitable for use in cosmetic preparations whereby it does not cause any crystallization in the fatty phase. The modified beeswax has so called self-emulsifying characteristics and displays an outstanding dispersant action for solid substances. The compatibility with pigmented products and mixtures of mineral products in an oil phase is good.

Abstract: The inventor has found that, irrespective of track thickness or the material of which the track is constructed, the optimum track width for a thick film heater track is in the range of from 1.2mm to 2.1mm. Further advantage accrues in that for a given resistance the track is longer and may be conformed to a pattern to give improved temperature distribution. 
     A heating element is also provided, comprising a plurality of thick film electrically resistive tracks (8) applied to the surface of an electrically insulative substrate and switching means (10) for selectively connecting one or more of said tracks to a power supply. The resistance and hence the operating temperature of the heating element may be varied by changing the track or tracks (8) connected to said switching means (10).

Title: Device for determining parameters of interest in living organisms.
Inventor: SKRABAL FALKO
IPC: A61B5/00
Filed: 1988-02-02
Abstract: In order to determine at least one parameter of interest in a living organism, a perfusion is directly introduced in the tissues. After its partial balancing by the tissue parameter of interest, the perfusion fluid is collected and analyzed for the parameter of interest, as well as for endogenous or exogenous marker properties indicative of the degree of interaction between the perfusion fluid and the tissue, in such a way that the parameters of interest can be determined with the help of such characteristic properties. Contrary to usual processes, used exclusively inside blood vessels or other body cavities filled with liquid, this process creates in the tissues, i.e. in the closed cellular structure, a previously inexistent cavity, in which the perfusion fluid introduced in the tissue interacts directly with the organic tissue, with no intervening membranes. The transfer of the measurement site into the tissue completely eliminates the risk of the thromboses and embolies, besides strongly reducing the risk of infection.

Abstract: A technique for transferring byte-wide serial data from a UART to a word-wide parallel data bus and vice versa is provided. Input control signals are established for the UART to specify the type of transfer to be implemented: odd byte, even byte or word. When a single byte is being sent from a CPU to a UART FIFO for serial transmission, then the predetermined storage location within the UART depends upon the address and the number of bytes being sent, not upon the byte's position on the data bus as is conventional. Similarly, when a serially received byte is to be transferred from a UART FIFO to the CPU, the next byte available is transferred to the data bus regardless of the position on the bus that it will occupy; in other words, regardless of whether it will be in the high byte or low byte position.

Abstract: The invention relates to a cellular digital mobile radio system including base stations (B m , B n ) and mobile stations MS₁, MS₂) with transmitters and receivers. The invention also relates to a method of transmitting message information digitally between mobile and base stations in such a system. 
     In accordance with the invention, at least two base station transmitters (B ma , B mb , B na , B nb ) at a given transmitting distance from each other are assigned to each of certain cells (C m , C n ) within a restricted geographical area. The base station transmitters which are assigned to the same cell transmit digitally modulated radio signals within the same frequency range at least partially simultaneously to the mobile stations of the cell. The radio signals from different base stations transmitters associated with the same cell are digitally modulated with the same message information to the mobile stations in the cell. 
     Different base station transmitters (9A, 9B) preferably transmit the digitally modulated radio signals with the same message information to a given mobile station with a given mutual transmission time shift. Here, the transmission time shift is selected individually for each mobile station, such that corresponding digitally modulated radio signals with the same message information to a given mobile station from different base station transmitters arrive practically simul­taneously at the mobile station.
