Patent AT-407698-B (AT)
IPC: F21Y115/10
Filed: 1999-09-02
Granted: 2001-05-25
Abstract: The invention relates to a lamp device which is worn on or directly in front of the forehead, respectively, or above or beside the eyes, respectively, and which ensures that the wearer's freedom of movement is neither restricted nor hindered by cables or other connections. The present invention is special in that several non-thermal, light-emitting elements are provided for the generation of light and that the individual light-emitting elements emit the light in a defined direction of radiation and are located in such a way that the light which is generated is directional. The light-emitting elements are located in such a way that each of them forms a particular angle with the visual axis of the wearer so that all light sources have a common intersection point just at the wearer's monitoring or working distance, respectively. Moreover, all individual light-emitting elements have the same distance to that intersection point. Furthermore, the vertical position of the area of illumination may be varied in front of the wearer's face.

Patent CH-631048-B (CH)
Inventor: LEUTHOLD OSKAR
IPC: G04F5/06
Filed: 1979-07-13
Abstract: The converter comprises a first MOS transistor fed by a current source or by a current-limiting element and it receives through an input capacitor the alternating input voltage. The first transistor is biased by a second MOS transistor the distance drain-source of which is connected between the gate and the drain of the first transistor. The second transistor is biased on its gate by a voltage of reference in such a way that its equivalent internal resistance takes a very high value. A filter capacitor is connected between drain and source of the first transistor. A direct voltage is delivered on the drain of the first transistor the value of which being function of the amplitude of the alternating input voltage. The converter can be implemented by any conventional technology for MOS integrated circuits because it uses only standards elements which are easily integrated.

Abstract: Facsimile data signal trains are transmitted from an originating station of Group 2 or Group 3 to a destination station Group 2 or Group 3 by way of an intermediate station. The scan line frequency of the facsimile data signal trains of the second group thereby amounts to n lines/second and m picture elements/line of the originals scanned whose information content is to be transmitted by facsimile data signal trains of Group 3. In the intermediate station, data signal trains of Group 2 are converted into data signal trains of Group 3 before intermediate storage and are subsequently intermediately stored, whereas data signal trains of Group 3 are intermediately stored without conversion. The data signal trains of Group 2 received in the intermediate station are converted into data signal trains of Group 3 before they are intermediately stored by demodulation, scanning with a frequency T2=mxn Hertz and coding of the samples according to a redundancy-reducing source code method.

Abstract: A ruminally inert fat for a ruminant feed is made by applying reducing sugars to oilseed meats and heating to induce non-enzymatic browning. The process is controlled to ensure penetration of the reducing sugars into the interior of cracked oilseed meat prior to browning. The browning reaction renders the protein which surrounds the oil resistant to rumen bacterial degradation to thereby encapsulate the oil in a protective matrix.
