Patent EP-0295463-A2 (EP)
Inventor: KUNZLE VIRGIL
IPC: C02F1/48
Filed: 1988-05-24
Abstract: A number of ring-shaped permanent magnets (35) are secured coaxially and at distances from one another in a cylindrical housing (20) with axial connections for inlet and outlet pipes (23, 29). The permanent magnets (35) feature a magnetic pole face at each end of their axes and they are arranged identically with respect to their polarity. Spacers (40) are situated between the adjacent permanent magnets (35), each spacer providing a free space through which lines of magnetic force run parallel to the axis. The spacers (40) also carry disc-like components (45) having openings (47) for the passage of water and having wings (48) which conduct the water passing through into the free spaces between the permanent magnets (35) in a helical circular motion and transverse to the magnetic field. During the passage of the water through the magnetic fields the salts dissolved in the water and, in particular, calcium carbonate are molecularly modified in such a way that afterwards they remain in the dissolved phase for a relatively long time and finally precipitate out in the form of microcrystalline sludge, which can be easily flushed away. <IMAGE>

Abstract: A device for producing light marks on an electrical module comprises a computer (1) and a projection device (2) connected thereto, which contains two deflection devices which can be controlled by the computer. The deflection devices direct the light beam onto coordinate points on the electrical module which are predetermined by the computer. Connected to the computer (1) there is an electrical module tester (5), which tests the electrical module (4) for electrical faults. The computer stores derived fault data in a fault data memory (1a). A position data memory (1b) contains the coordinates of all the theoretically possible fault locations of the electrical module, under their addresses. By comparison, the computer determines the position data associated with the fault data and transmits this information to the projection device which uses it to produce the control signals for the deflection devices. <IMAGE>

Abstract: The invention relates to a method and an apparatus for manufacturing of a magneto-optic recording and erasable information carrier. This involves applying various chemical substances as layers on a substrate (4) by means of a magnetron-sputtering system. The proportional composition of the layers is controlled by altering the magnetic field strength of the magnetron (1). By means of a suitable measuring instrument (51, 58), the compensation temperature of the respective layer is monitored and compared with a desired value. If the two compensation temperatures differ, the desired value can be set by adjusting the cathode voltage Uc, which in turn takes place by means of a controller (63) by adjusting the distance of the magnets (8, 9, 10) of the magnetron (1) from the target (6).

Abstract: Where a signature is to be automatically verified, or data is to be entered into a computer, a special pen is usually employed but this pen is liable to be stolen or vandalised. In the present invention the tip 15 of an ordinary pen presses lined paper 12 on to a transparent plate 10 and modifies internal reflection in the plate at the point of contact. A light source 13 edge-illuminates the plate and light received by a receiver 14 at another edge of the plate varies in intensity as the pen tip crosses the lines. By measuring the intervals between crossing line boundaries information is obtained which can be analysed for use in signature verification and data entry.

Abstract: A first line of cellular defense against many viruses, including those causing AIDS, is activation of an intracellular biochemical system termed the 2ʹ-5ʹ oligoadenylate/RNase L pathway. It is well known that this pathway malfunctions in individuals with progressive AIDs-related immune dysfunction, but the mechanism of malfunction remained obscure. An inhibitor substance, released in HIV infected cells or a virus directed inhibitor of biochemical intermediates in the 2ʹ-5ʹA/RNase L pathway, Which by apparently physically attaching to the terminal product (RNase L) in the biochemical pathway, causes the entire system to malfunction which thus allows HIV to multiply uncontrollably has now been identified. The relative intracellular level of this newly-isolated inhibitor has prognostic significance with respect to the development of full-blown AIDS and eventual death.

Abstract: There is disclosed apparatus and methods for sensing electrical signals generated in a living body and mapping these signals to MIDI code. The apparatus senses electrical signals generated in the body through electrodes (12, 14, 16) on the skin or implanted in various areas of the body. The electrical signals are then amplified (24), filtered (26) and converted (28) to digital data. This digital data is analyzed to determine characteristics of the electrical signals such as amplitude, frequency, change in amplitude or change in frequency. These characteristics are then mapped (36) to MIDI code or other code to control the generation of musical (38) notes or video (40) display information. There is also disclosed a method and apparatus for determining the alpha wave or other content of brain waves by taking a fast fourier transform of the brain wave and determining the coefficient for the fourier frequency component at the frequency of desired frequencies. Further, a method of altering MIDI code generated from biopotentials is disclosed where the effect of musical notes generated by the MIDI code on the biopotentials causes changes in the MIDI code. A similar method is also disclosed wherein MIDI code received from another machine is changed based upon mapping of biopotentials from the body of a subject.
