Title: Method of protecting security documents
IPC: B42D15/02
Filed: 1986-02-14
Granted: 1990-05-23
Abstract: The method is applicable to protecting security documents of the type comprising a substrate bearing information which is to be protected from tampering, together with transparent protective layers of thermoplastic material heat sealed around said substrate. The method provides a set of pigment-retaining micro-holes in the substrate, said pigment being soluble in protective layer solvents. Any attempt at dissolving away the protective layers to gain access to the support for tampering with the information thereon, will also have the effect of making tell-tale marks on the support, as it absorbs the pigment is spread in the thickness of the support like ink in blotting paper.

Abstract: A process is disclosed for accurately maintaining a low alumina content of between 1 and 4.5% in a cell for the production of aluminum by electrolysis in the Hall-Heroult process. According to the invention, a control parameter P=-1/D(dR1/dt), is determined, wherein D is the variation in the alumina content of the electrolytic bath in % weight per hour, R1 is the internal resistance of the cell, and t is the time. A series of operations is then carried out in a repeated cycle, starting with the cell being fed alumina at a nominal rate which is substantially equal to the quantity consumed by electrolysis. At periodic intervals, an over-supply of alumina is added in order to enrich the bath, and the over-supply is continued for a preset time during which dR1dt is negative. The feed rate is then reduced to less than the nominal feed rate, during which time dR1dt passes through zero to become positive and the regulation parameter P, the value of which tends to rise, is measured often. The successive values of P are compared with a required preset value Po. As soon as P equals Po, the feed rate is returned to the nominal feed rate and a new cycle is recommenced.

Title: Method of individually marking pre-baked anodes for the electrolytic production of aluminium
IPC: G09F3/00
Filed: 1987-06-12
Granted: 1991-08-07
Abstract: The invention relates to a method for the individual marking of precooked anodes used in the production of aluminum by electrolysis in the Hall-Heroult process, and to the anodes produced thereby. These anodes are produced by hot compaction of a carbonaceous paste, and according to the invention, during or immediately after such compaction, a plurality of impressions is formed in the upper part of each anode. The impressions are depressions and/or relief portions, constitute a digital coding for the identification number of each anode, and remain legible until withdrawal of the components of the butt of the worn anode from the electrolysis tank. The marking can be carried out using a binary or ternary code, where the reference plane of the zone of the anode which carries the marking corresponds to a first digit, with other digits corresponding to depressions of a particular depth, depressions of a greater depth, or relief portions.

Abstract: A cardiac valve prosthesis in which the inner area of the valve ring has an internal cross section continuously decreasing in flow direction. The valve ring is shaped like a nozzle, and flow disruption occurs only at the nozzle end, allowing a concentric flow discharge. Vortex formation at the jet boundary and inside the flow is inhibited. As a result, flow resistance is reduced and blood damage is minimized. A flushing channel traverses the joint cavity in order to avoid deposits of blood particles in the valvular joint.

Abstract: In an apparatus comprised of a ring-shaped nozzle in a nozzle piece, which ring-shaped nozzle has a reciprocally movable nozzle cone piece, wherewith the cone piece and nozzle piece together define a ring-shaped nozzle opening, it is desired to modify the ring-shaped nozzle such that, in the manufacturing of hollow bodies, the amount of scrap can be reduced and the range of practicable applications of the apparatus can be extended. This is achieved in that an additional device or arrangement is provided for closing the nozzle opening. With the improved apparatus, one can achieve improvements in the hollow body being produced, the improvements being attributable to a special technique of closing the ring-shaped nozzle, which technique is enabled by the novel closure device.

Abstract: The kit (1, 20) contains a sample application zone (3) which has a sample layer (6b, 29b, 29c) with a sample field (10, 37, 38) for application of a stool sample, and analysis means with reagents which react with the analyte and include a component generating a detectable signal. A considerable simplification of, in particular, immunological determinations is achieved by the sample layer (6b, 29b, 29c) being composed of a material which has capillary activity so that a liquid is transported therein by capillary action. The sample layer is, on the one hand, in contact permitting fluid exchange with an eluent application zone (2) so that an eluent applied there penetrates into the sample layer and elutes an analyte which is contained in the sample and is soluble in the eluent. The sample layer is, on the other hand, in contact permitting fluid exchange with an eluent pickup zone (4) from which the eluent with the eluted constituent is picked up and passed to the analysis means.   <IMAGE>

Granted: 1993-05-19
Abstract: In a system for recognizing a time sequence of feature vectors of a speech signal representative of an unknown utterance as one of a plurality of reference patterns, a generator (11) for generating the reference patterns has a converter (15) for converting a plurality of time sequences of feature vectors of an input pattern of a speech signal with variances to a plurality of time sequences of feature codes with reference to code vectors (14) which are previously prepared by the known clustering. A first pattern former (16) generates a state transition probability distribution and an occurrence probability distribution of feature codes for each state in a state transition network. A function generator (17) calculates parameters of continuous Gaussian density function from the code vectors and the occurrence probability distribution to produce the continuous Gaussian density function approximating the occurrence probability distribution. A second pattern former (18) produces a reference pattern defined by the state transition probability distribution and the continuous Gaussian density function. For a plurality of different training words, a plurality of reference patterns are generated and are memorized in the reference pattern generator.
