Patent DE-3270735-D1 (DE)
Title: Digital repeater circuit
Inventor: CATCHPOLE RICHARD JOHN
IPC: H04B3/36
Filed: 1982-06-01
Granted: 1986-05-28
Abstract: Feedback equalization is employed for digital repeaters of transmission systems having twisted-wire pairs, in order to reduce intersymbol interference while minimizing near-end crosstalk gain. Previously the incoming signal was selectively amplified at the higher frequencies in order to negate intersymbol interference, with subsequent near-end crosstalk gain. According to the present invention the intersymbol interference element of an incoming signal is cancelled, prior to amplification in an adder by a compensation signal derived from the output signal of a regenerator and a retimer. An output stage serves to amplify and shape the resultant signal to a form suitable for transmission. The compensation signal comprises the inverted output of a filtering and scaling network.

Title: Compositions of the "emulsion explosive" type, process for their manufacture and use of these compositions
Inventor: LIBOUTON JEAN-CLAUDE
IPC: C06B23/00
Filed: 1983-03-18
Granted: 1989-09-07
Abstract: An explosive composition of the water-in-oil emulsion type includes at least one emulsified gel formed of an oxidizing solution of an inorganic salt dissolved in water and a fuel phase containing a liquid hydrocarbon and an emulsifier in combination with an inert or reactive lighting constituent and, if appropriate, one or more oxidizing salts or metal fuels.

Granted: 1988-07-07
Abstract: A method of separating metal particles where particles of the one metal exhibit a higher degree of friction against a surface than particles of the other metal, particularly for separating lead particles and copper particles one from the other. In accordance with the invention a layer of a mixture of the metal particles is deposited, by means of a feed conveyor (4) or the like, onto the peripheral surface (8) of a drum (3) which rotates about a horizontal axis (7). The material is deposited at a location on the drum (3) spaced at a distance (a) from a vertical plane (10) through the drum axis (7), in a direction opposite to the rotational direction of the drum, this distance (a) being adapted so that those particles which exhibit greater friction against the peripheral surface (8) of the drum (3) than the other particles are carried by the drum in its direction of rotation, while the other particles are moved in an opposite direction gravitationally.

Patent DE-3668377-D1 (DE)
IPC: G01N15/04
Filed: 1986-02-24
Granted: 1990-02-22
Abstract: A complex liquid, such as a biological liquid, is stratified, as by centrifugation in a tube, into constituent layers. The most dense or heaviest constituent layer is measured volumetrically by physically expanding the entire layer with a cylindrical float which is inserted in the tube and which occupies the portion of the tube also occupied by the constituent layer being measured. The axial extent of the expanded layer is measured to provide an indication of the volume of the layer being measured. The end of the tube proximate to the layer being measured contains a plug of a more dense material which is immiscible with the subject liquid and into which the float will settle during centrifugation. The float thus settles into the plug of dense material and "floats" therein so as to extend through the entirety of the layer being measured.

Abstract: The invention relates to a shaped cleansing composition containing an alkali, earth alkali or ammonium perborate anhydride and at least one cleansing constituent. The improvement consists in that the cleansing composition also contains an alkyl salicylate of which the alkyl group has 1 to 4 carbon atoms. It is preferred that use should be made of methyl salicylate. Alkyl salicylate prevents the shaped composition from going sticky and promotes the solubility of the composition in water.
