Abstract: Disclosed is an improved combustion products smoke alarm that includes  an  electronic  circuit  which automatically tests  the detector's  operation  repetitively  at  periodic  intervals,  or periodically sounds the detector's alarm to remind the occupant to manually  test  the  detector' s operation.  In  the  preferred embodiment, this periodic testing or reminding occurs at weekly intervals.  Thus, occupants living about such a smoke alarm, after experiencing this repetitive sounding of the detector' s alarm for some time, will come to anticipate its sounding and notice its absence if the smoke alarm becomes inoperative.

Abstract: The present invention relates to reinforced pressure-sensitive adhesive tapes, and to a method and apparatus for making these tapes. Reinforced tapes, also known as filament tapes, generally comprise a backing having adhered to one major surface thereof a plurality of yarns, which comprise a multiplicity of glass or synthetic polymeric filaments, by means of an adhesive. Alternatively, the yarns can be replaced by individual filaments.  Typically, a layer of pressure-sensitive adhesive is then applied over the yarn- or filament-bearing surface of the tape. Although filament tapes are extremely useful, the cost of making them is high because of the high cost of filaments and the high cost of processing.  In order to reduce the cost of making filament-reinforced tapes, some manufacturers have resorted to reducing the number of filaments adhered to the backing. However, this expedient reduces the tear strength of the tape. The present invention provides a tape comprising a backing bearing on at least one major surface thereof a plurality of ribs disposed substantially longitudinally thereon, and further bearing on at least one major surface thereof a layer of adhesive. The ribs are joined to the backing such that the contact angle between the ribs and the surface of the backing ranges from about 10.degree. to about 160.degree.. At least 50% of the cross-section of the ribs must project from the rib-bearing surface of the tape. It is preferred that the adhesive be a pressure-sensitive adhesive. The tape of this invention can be prepared by means of coextrusion techniques.

Abstract: METHOD FOR STABILIZING HETEROLOGOUS PROTEIN    EXPRESSION AND VECTORS FOR USE THEREIN                Abstract of the Invention The present invention provides a method for stabilizing heterologous protein expression in bacteria by using a 3' truncated chloramphenicol acetyltransferase (CAT) gene fused in frame with a gene encoding a heterolo-gous protein.  When expressed in a bacterial host, the resulting hybrid gene produces a fusion protein in re-coverable yield.  Cleavage sites separating the CAT and heterologous protein are also provided to facilitate isolation and purification of the desired heterologous protein   The invention further provides bacterial vectors containing the hybrid gene fusions for expression of the fusion protein comprising the desired heterologous protein.

Abstract: A method of making solid glass articles by the flame hydrolysis technique. A thin stratum of low viscosity glass soot is applied to the surface of a mandrel. First and second coatings of glass soot are deposited on the surface of the thin stratum to form a porous preform. The refractive index of the soot particles of the first coating is greater than that of the soot of the second coating, and the soot of the first coating has a viscosity lower than that of the second coating. The mandrel is removed, and the soot preform is subjected to a high temperature whereby it is consolidated to form a dense glass blank. The glass surface tension and the relative viscosities of the inner and outer portions of the preform cause the aperture to close during the consolidation process. The thin stratum, which preferably includes P2O5, smoothes over the damage caused by removing the mandrel and reduces or even eliminates seed formation at the axis of the resultant glass blank. The blank may be heated and drawn into a filament, or it may be sliced into optical windows, lenses or the like.

Abstract: Structural assembly, more particularly for a shower partition, comprising a door support in the form of a profiled rail having, in an outer face thereof, a first channel, of which one side flange forms a groove, and a facing panel mounted in this first channel. The facing panel is held in the first channel by a connecting element fitting in the groove. Existing arrangements of this type are relatively wide, of correspondingly large structural volume, and of high material costs. In order to obtain a structurally simple and inexpensive connection between the facing panel and the profiled rail, it is proposed that the panel be provided with a longitudinal second channel which opens towards the groove of the first channel. The connecting element engages partly in the second channel and partly in the groove.

Abstract: The adjusting mechanism is used for exerting a force on two components moveable relative to one another and comprises a cylinder, a piston and a piston rod. A guide rod is also provided on the piston and is guided in a guide connection of a bottom cylinder casting. A control piston is displaceably guided in a longitudinal bore of the piston and in a further longitudinal bore of the guide rod. The piston contains transfer ducts, which are either obturated by the control piston or are freed or exposed by a smaller diameter portion of the control piston. An inner cylinder chamber is completely filled with a flowable or fluid grease. As a result, the piston rod can be locked in position by the control piston closing the transfer ducts and, on releasing or opening the latter, the piston rod can be moved. The locking of the adjusting mechanism in a specific position, as is particularly required in the case of tiltable chairs, is consequently facilitated in comparison to known adjusting mechanisms. In addition, by using flowable grease, the sealing of the adjusting mechanism is made simpler.

Abstract: FIELD: nuclear physics. 
     SUBSTANCE: method of determining density and radioisotope composition of fission-fragment products contaminating an area and formed as a result of a nuclear explosion or emissions from atomic industry plants, from an aeroplane (helicopter) or automobile, is based on measuring radiation energy of contaminating products using a spectrometre. The spectrometre registers separate gamma-ray lines. Gamma-ray intensity at any energy is measured using two detectors in two known solid angles and, knowing height on which measurement is taken and efficiency of the detectors, "penetration coefficient" is determined, from which density of contamination of the area with the given isotope is determined. 
     EFFECT: identification of a range of equilibrium isotopes with quantitative determination of their density.

Abstract: Abstract of the Disclosure:          In a method of recognizing an input pattern represented by a time sequence of input feature vectors (a(t)) as a recognized pattern selected from a plurality of reference patterns which represent categories of recognition objects, respectively, each of the reference patterns is defined by a sequence of state models, successively supplied with the time sequence of the input feature vectors and with a sequence of preceding state vectors (h(t, s, n)), the sequence of the state models produces a time sequence of predicted feature vectors (A(t+l, s, n)) and a sequence of new state vectors (h(t+l, s, n)).  The recognized pattern is selected from one of the reference patterns that minimizes a prediction error between the time sequence of the input feature vectors and the time sequence of the predicted feature vectors.  The prediction error is calculated by using a dynamic programming algorithm.          Training of the reference pattern is carried out by a gradient descent method such as back-propagation technique.
