Abstract: "CONCRETE ARCH BURIED BRIDGE"               Abstract of the Disclosure A concrete arch buried bridge made up of upper and lower arched parts of corrugated metal provided with a reinforced concrete cap with a footing at each side, having an abutment extending inward under the margin of the upper part.  The margins of the respective upper and lower parts have a connection which can be left loose to enable their relative movement and tightened so that they are rigidly held together.  Each margin of the lower part has a permanent connection to the adjacent abutment which allows movement in the upward and downward direction, but resists lateral movement.  The bridge is constructed by first placing the lower part on a compacted fill and making the connection between the margins of the upper part and the lower part.  Then, the concrete cap is formed on top of the upper part and when the concrete is set sufficiently, the connection loosened and the fill completed on top of it.  The weight of the concrete and the fill will cause the upper part to settle and move downward relative to the lower part.  When the structure has settled the connection may either be tightened or left somewhat loose with provision made to prevent the lower part rising.

Abstract: AN IMPROVED DISC BRAKE                Abstract of the Disclosure An improved disc brake is of the type which includes a disc mounted for rotation about an axle.  A brake housing is mounted on the axle in alignment with a friction surface of the disc.  An axially movable, non-rotatable braking piston has an interior end at least partially mounted within the housing and an external end outwardly of the housing adjacent the friction surface of the disc.  Brake actuation means is mounted on the housing.  A powershaft is mounted within the housing in a hole in an end thereof in coaxial alingment with the braking piston and is capable of selective rotation by the brake actuation means.  The powershaft has worm gear teeth thereon engaged with mating teeth on the interior end of the braking piston to produce axial movement of the braking piston toward and away from the friction surface of the disc directly corresponding to the selective rotation of the powershaft.  The improvement includes a powershaft being retained within the housing by a radially extending shoulder portion thereof which overlies an interior surface of the end of the housing.          A steel thrust washer is between the shoulder and the interior surface and has a polytetrafluoroethylene material at a surface thereof adjacent the shoulder portion.  The thrust washer has an upset portion thereof extending toward the end of the housing.  The interior surface is provided a recess for receipt of the upset portion therein to prevent rotation of the thrust washer relative to the end of the housing during selective rotation of the powershaft.

Abstract: ABSTRACT OF THE DISCLOSURE       A speech recognition method and apparatus for detecting and recognizing one or more keywords in a continuous audio signal is disclosed.  Each keyword is represented by a keyword template which corresponds to a sequence of plural target patterns, and each target pattern comprises statistics representing each of a plurality of spectra selected from plural short-term spectra generated according to a predetermined system for processing of the incoming audio.  The spectra are processed to enhance the separation between the spectral pattern classes during later analysis.  The processed audio spectra are grouped into multi-frame spectral patterns and are compared by means of likelihood statistics with the target patterns of the keyword templates.  Each multi-frame pattern is forced to contribute to the total score for each keyword as represented by the keyword template.  A concatenation technique employing a loosely set detection threshold makes it very unlikely that a correct pattern will be rejected.

Abstract: ABSTRACT            A looking apparatus intended to lock two objects, for instance skies, to each other, comprises two locking members (1,10) from which one (I) has a transverse, dovetail shaped projection (3) and the other one (10) has correspondingly shaped groove (12). Thus the locking members may engage each other by means of a dis-placement movement. Securing of the locking members in engaged posi-tion is accomplished by means of a cylinder leek (17) which may be inserted into the locking apparatus when the members thereof are engaging each other owing to the fact that part openings in said members in said engaged position together form a cylindrical cavity, which extends into the locking apparatus to such an extent that it engages the projection (3) and the groove (12) communicating there-with. The cavity further has an undercut in which the lock plunger (18) of the cylinder lock may engage for securing she lock cylinder in inserted position.

Abstract: ABSTRACT                         STERILIZER     A sterilizer for hospital and field use uses ozone, water, and ultrasonic energy, which will kill even the most difficult bacteria and spores in shorter times than ethylene oxide sterilizers and which can be used for instruments which cannot stand steam temperatures or pressure changes.  Because no pressure chamber or heat is required, the sterilizer is much lighter, portable, and cheaper.      An article to be sterilized is suspended over a water bath through which ozone is bubbled, the moist ozone contacting the article.  The article is then immersed in the water and subjected to ultrasonic vibration for short periods to dislodge the bacteria and improve water/article contact.
