Abstract: A foot protector for use in combination with stocking-type hosiery to cushion and protect a wearer's foot is described. The foot protector is preferably knit to include padding in the form of integrally knit terry loops, and has a specially constructed top portion for encircling the wearer's ankle. The top portion extends upwardly to a greater extent proximate the wearer's heel than the instep, and is substantially unpadded. When the foot protector is worn in a layered relationship with a stocking and a shoe, the protector is only minimally visible, if at all, thereby providing enhanced wearer comfort while maintaining the appearance of wearing stockings and shoes alone.

Abstract: A method of and apparatus for sorting plastic items is disclosed. The method comprises the steps of transmitting polychromatic light from a source through each individual item; detecting the quantity of light of a first color passing through each individual item with a detector opposed to the source as a stream of the items is successively directed past the source and the detector; detecting the quantity of light of a second color passing through each individual item with the detector, wherein the second color is different from the first color; and selectively removing individual items from the stream, the removal being based upon a comparison of the quantity of light of the first color detected and the quantity of light of the second color detected.

The cutter has a longitudinal bore therethrough defining a fluid passageway. The chuck has a longitudinal bore at least partially therethrough for gripping the cutter and defining a fluid passageway. The bore of the chuck is in fluid communication with the bore of the cutter. The chuck includes opposed ends and a medial portion disposed between the opposed ends. The medial portion includes longitudinally spaced-apart, circumferential lands which define bearing surfaces for engaging the inner surface of the cutting fluid gland. The medial portion has an opening therein defining a fluid passageway. The gland has an opening therein defining a fluid passageway.

Abstract: A microactuator for precisely aligning an optical fiber with an optical device includes a carrier having at least one bimorphic actuator which bends or deflects in response to electrical stimuli to thereby controllably position the carrier and, in turn, an optical fiber mounted on the carrier, with an optical device, such as a laser diode. The bimorphic actuator includes first and second layers of first and second materials, respectively, which respond differently to electrical stimuli. For example, the first and second materials can have different coefficients of thermal expansion or one of the materials can be a piezoelectric material such that application of electrical stimuli to the bimorphic actuator will deflect the actuator by a precisely controllable amount. The carrier can also be mounted on an alignment support structure such that upon deflecting the bimorphic actuator is urged against a portion of the alignment support structure so as to move the carrier relative to the alignment support structure.

Abstract: A process for producing industrial denier filaments of a thermoplastic polymer at higher rates of production than those using liquid quenching media is disclosed. Liquid polymer is extruded in the form of hollow filaments at a throughput and rate of take up that produces individual filaments of greater than about 30 denier. A flow of gas is then directed at the liquid filaments at a flow rate and temperature that are sufficient to quench and solidify the individual filaments in the absence of any other quenching fluid. The filaments formed by the disclosed process have larger diameters than solid filaments of the same denier.

Abstract: A method and apparatus for detecting high impedance faults and other arcing phenomena in an electrical distribution system. Electrical signals on the distribution system are monitored and a number of frequency components isolated, such as zero-sequence current and voltage, second harmonic voltage, third harmonic current, eighth harmonic voltage and current, and a measure of magnitude of the components are taken over successive data acquisition periods. The measures of the component magnitudes are formed into a pattern for each data acquisition period, and the difference between patterns for successive periods are compared against a pattern threshold which is set to suit the characteristics of the distribution system. A pattern difference greater than the pattern threshold indicates the possibility of an arcing fault, which can then be confirmed by determining whether the frequency components are modulated at twice the fundamental frequency of the distribution system.

Abstract: A process and an apparatus for the typographical labeling of folded printed products, such as folded individual sheets or folded publications, on an inner side, in particular in the border region of the inner side, is designed for carrying out this typographical printing in folded printed products which are conveyed with their fold approximately at right angles with respect to the conveying direction, and can thus be used with the conveying systems which are conventional nowadays in printing works for conveying printed products in the form of imbricated streams. The front and rear halves of the respective folded printed products are moved apart via an opening device, with the result that a printing head can carry out the desired typographical-labeling operation on the inner side of the folded printed product.
