Abstract: Abstract of the Disclosure:         In a squelch signal generator (11) responsive to a digital input signal (IN) which draws an eye pattern having at least one eye at each time instant appearing at a predetermined period, a squelch threshold level (VS) is preselected outside of a predetermined one of uppermost and lowermost cross-points of at least one eye.  A squelch comparator (41) compares an input level of the input signal with the first squelch threshold level to produce a result signal representative of a first result of comparison.  The result signal is processed at each time instant by a processing circuit (42, 48, 50, and 51) into a squelch signal when the input signal is classified into an undesired signal.  An additional squelch threshold level may be preselected outside of the other of the uppermost and the lowermost cross-points.     (Fig. 1)

Abstract: FLIP-OVER MECHANISM            ABSTRACT OF THE DISCLOSURE           A flip over mechanism for a cyclometer register includes an eccentrically balanced fly-wheel freely rotatable on a drum shaft between a driver drum and a first driven drum, each drum being marked with decimal digits 0-9.  The driver drum is driven in smooth rotation by a measuring device whose measurements are to be accumulated.  At a certain point in its rotation, the driver drum engages and begins rotating the fly-wheel.  As the driver drum is rotated into a position at which it performs a 9-to-0 transition, the fly-wheel becomes overbalanced and rotates forward on its stored potential energy until a striker thereon engages a tooth of a first carry pinion located between the fly-wheel and the first driven drum.  This applies a momentary forward tap to the first carry pinion.  The tap on the carry pinion provides a substantially instantaneous carry operation to be performed in all of the driven drums which are in position to require a carry.  The mass of a replaceable weight on the fly-wheel is selected to apply the correct imbalance for producing a smooth operation.

Abstract: CLOSURE CAP CONSTRUCTION           Abstract A compact, high-flow-rate closure cap construction for hand-held dispensers, comprising a cap body having an upstanding tubular discharge neck portion, and a clo-sure cap having a bore receiving the neck portion. The neck portion has a cylindrical exterior sealing surface, and the bore has a sealing annulus engaged with the ex-terior sealing surface. The closure cap is axially slid-able on the neck portion between a closed sealing posi-tion and an open, product-discharging position. The bore of the neck portion contains multiple product-flow dis-charge passages which enlarge the effective cross-sec-tional area of the bore so as to increase its flow-han-dling capacity, with a minimum of loss in its stiffness and rigidity. The cap has a discharge orifice that is normally closed off by a stopper peg carried by a bridge on the cap body. On the underside of the peg is a re-lieved area in the form of a slot, that increases the size of one of the openings constituting the discharge path, thereby facilitating an increased volume of prod-uct flow. In addition, the cap has an expansive inside wall surface along which the product flows. This surface in turn has a plurality of recesses or discharge pas-sages. The advantage is that there is decreased resist-ance to product flow without sacrificing wall stiffness or jeopardizing the ability to readily mold the parts out of the desired plastic substance.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for measuring stress and strain associated with a pipe, pressurized vessel, structural member or deformable body contain-ing a flaw or stress concentration utilizes a laser beam to illuminate a surface being analyzed and an optical data digitizer to sense a signal provided by a speckle pattern produced by the light beam reflected from the illuminated surface.  One signal is received from the surface in a reference condition and subsequent signals are received from the surface after surface deformation.  The optical data digitizer provides the received signal to an image processor, and the processor stores the signals and correlates the deformed image received with the reference image and then sends this correlated information to a minicomputer which performs mathematical analyses of the signal to determine stress and strain associated with the surface.  The apparatus is constructed as one integral unit, and further includes a digital and tape display, as well as a television monitor and an electro-optic range indicator.
