Abstract: ABSTRACT OF THE DISCLOSURE:       Fire indication, derived from a sensor, is tested whether it exceeds a first threshold level; if it does, the signal is integrated in an integrator which has a slow, or long time constant to integrate a rising signal, but a short, rapid time constant to discharge, upon drop of the signal; in one form, the integrator includes a diode in the integration circuit, so that it will discharge an integrating capacitor rapidly, upon drop in signal level exceeding the first threshold. When the integrated signal exceeds a second threshold, an alarm is give.  Providing for rapid discharge of the integrated signal prevents false alarms resulting from repetitive short pulses exceeding a first threshold level which, however, do not persist.

Abstract: ABSTRACT OF THE DISCLOSURE:     A continuous casting plant for slabs, comprising a water-cooled mould from which the strand is continuously extracted, a supporting- and guiding means having rollers for guiding the strand between them, and a cooling device having nozzles for spraying a coolant, in particular water, onto the strand and the rollers, wherein a part of said cooling device is formed by flat jet nozzles arranged parallel to the surface of the strand, their longitudinal axes being parallel to the axes of the rollers, and two flat jet nozzles are arranged between neighbouring rollers. Advantageously, the flat jet nozzles are arranged within the area defined by the slab edges of the slab sizes to be cast in the plant, and advantageously they are arranged opposite, toward each other. Furthermore, the flat jet nozzles can have nozzle openings in opposite directions, each opening pointing toward the slab edges. Advantageously, the flat jet nozzles are displaceable in the direction of the roller axes and are thus adjustable to various slab widths.

Abstract: A B S T R A C T   O F   T H E   D I S C L O S U R E           A method and apparatus for rapid automatic comparison of two patterns, such as fingerprints, each of which may be randomly located and oriented within some bounded area.  The patterns, or portions thereof, are optically superimposed and rapidly scanned with respect to each other in a rotated scan pattern.  Reflected or transmitted incoherent radiance is sensed to provide a measure of the correlation between the two patterns.          Logic circuitry including a threshold decision function signifies pattern identity or dissimilarity by activating a panel light, audible signal or other suitable indicator.  Optical baffling and spatial and electronic filtering enhance correlation signal discrimination and supress spurious modulation responses.

Abstract: ABSTRACT  In the manufacture of multiple-glazed window units having a heat-cured peripheral seal, a dark-coloured heat-curable sealing material, such as a black polysulphide rubber, is cured by radiant heating, e.g. by infra-red heating directed at the periphery of the units, so as to heat the sealing material while minimizing the heat-ing of the air within the space or spaces between the panes of the units, thus reducing the problem of peripheral spacer blow-out.  The process can be carried out in a tunnel oven through which stacks of the units are transported on conveyors, the stacks being turned through 90° at an intermediate point to expose all sides of the units to the radiant heat from infra-red heaters disposed along the sides of the oven.

Abstract: ABSTRACT             An apparatus and method for continuously forming and filling tampon overwraps or sacks wherein a web of pouch forming material is unwound from a supply roll, passed through an adhesive printer which applies spaced apart transverse stripes of heat activatable adhesive which ultimately form end seals for the sacks, the adhesive being dried on a drying drum having raised portions which coincide with the transverse stripes of adhesive.      The web proceeds to a hollow tube forming mandrel and is formed around the mandrel with the longitudinal edges of the web over-lapped and sealed to form the longitudinal seam of the tubing.      The formed tubing is tangentially received by a rotating turret having a plurality of pleating and sealing stations spaced about its periphery, the spacing between adjoining stations correspond-ing to the spacing of the transverse stripes of adhesive on the tubing.  Each station has a pleater which sequentially engages and gathers the tubing and sealing jaws which engage and seal the gathered tubing in the areas of the transverse adhesive stripes to form a continuous series of sacks.  As the leading end seal of each successive sack is formed, a charge of particulate absorp-tive material is introduced through the tubing into the sack being formed, the hollow mandrel having a funnel-like hopper into which measured increments of the absorptive material are deposited, an air jet in the mandrel acting to propel the material from the mandrel and through the tubing so that the material comes to rest against the leading end seal of the sack being formed, whereupon the formation of the next successive end seal completes the sack and encloses the deposited charge of material.      Adjustment means are provided to establish the pitch distance between adjacent sets of sealing jaws as the turret rotates to insure accurate registry of the transverse adhesive stripes with the sealing jaws both during start-up and normal operation, and phase adjustment means are also provided to initially synchronize turret rotation with tube movement.
