Abstract: A file cabinet having vertically arranged horizontally movable drawers and an anti-tip lock mechanism that permits movement of a single drawer from its closed to its opened position while simultaneously locking the remaining unopened drawers against movement from their closed to their opened positions.

Abstract: A centrifugal balancer is combined with a computer system programed to suggest trial weights and placement and correction weights and placement to be used in interactive menu driven balancing sequences. Vibration responsive transducers provide inputs to automatic multi-gain amplifiers in a computer interface. The signals produced by the amplifiers are filtered by adjustable bandpass filters which are driven to match the rotational frequency of the work piece being balanced. Peak detectors rectify the output of the filters and an analog-to-digital converter processes the output of the peak detectors. A counter, reset by a sensor monitoring work piece rotation, is incremented until disabled by zero crossing detectors monitoring the outputs of the filters to provide relative phase information.

Abstract: There is disclosed in connection with a random orbital sander the utilization of improved arrangements for resiliently supporting an air motor, controlling the flow of pressurized air to the motor, and utilizing air exhausted from the motor to withdraw dust from a shroud arranged to collect dust generated incident to operation of the sander. Also disclosed is an alternative dust collecting arrangement, wherein the shroud is connected by a sander mounted duct to a source of vacuum.

Abstract: A flexible sanding/deburring head adapted for driven rotation by a power tool is formed from a plurality of juxtaposed thin sheets of flexible abrasive material individually die cut to define a connecting portion having a mounting opening disposed centrally thereof and at least three projections connected to the connecting portion to extend generally radially of the mounting opening, wherein the projections are uniformly spaced annularly of the mounting opening and bound uniformly sized cut-out areas opening radially of the mounting opening and each projection is divided into parallel fingers having relatively inner ends connected to the connecting portion and relatively outer ends arranged to lie generally along arcs of a circle whose center is coincident with the center of the mounting opening. The projections are skip-cut to define the fingers.

Abstract: A device for testing visual contrast sensitivity is disclosed whereby the contrast between a vectographically polarized test symbol and a reference background may be continuously varied by changing the direction of polarization of a polarization analyzer situated along the test axis. The invention is practiced by providing a chart projector or a conventional refractor with a rotatable analyzer.

Abstract: A vertical position and gravity map aided INS is self contained (no external signals required); covert (no signals emanated); unrestricted in operating area; able to operate in quiet or active gravity regions; and able to be configured with proven instruments.

Abstract: A unitized expanding dowel is disclosed for accurately and repeatably locating a part having a through hole relative to a reference part having a hole of like size. The dowel includes a radially expandable, resiliently deformable cylindrical sleeve having an axial passage therethrough. A portion of the passage is frusto-conically shaped to complement a tapered expansion pin movable within the axial passage in a first axial direction to force the outer surface of the sleeve to radially expand into tight surface engagement with inner surfaces of the holes. Coupling means connect the sleeve to the expansion pin and permit movement of the pin in an opposite direction to allow contraction of the sleeve away from tight engagement with the holes while preventing withdrawal of the pin from the sleeve passage.

Abstract: An apparatus and method for creating an aligned subassembly of optically critical components of a temperature compensated, hand-held refractometer prior to installing the subassembly in a refractometer housing is disclosed. The preferred embodiment is a plastic subassembly frame with a critical angle prism reference surface, a temperature responsive member fulcrum, a compensating prism mount, an objective lens mount, and a reticle mount.

Abstract: An automatic slack adjuster operating to effect reduction of slack present in a vehicle brake system upon brake release incorporates a member cooperating with a slack adjusting rotor to determine a reference position for the rotor and to return the rotor to such reference position at the completion of each brake operational cycle.

Abstract: An autonomous covert Inertial Navigation System uniquely suited for underwater applications wherein Schuler and siderial errors are bounded without external navigation aids or active instrumentation of ground speed is achieved by integrating a conventional Inertial Navigation System with a gravity gradiometer capable of measuring gravity field components independently of platform accelerations.

Abstract: A golf swing training process comprising the steps of:(a) providing a golf swing training device having a support frame, a force translation member, and a pivot, said support frame supporting said pivot for rotation about a generally vertical axis and enabling the vertical position of said pivot to be adjusted, said force translation member having two ends and being engaged with said pivot for pivoting said ends about said generally vertical axis;(b) adjusting the vertical position of said pivot such that said force translation member is substantially the same distance above ground level as one's knees;(c) assuming a golf stance wherein one's legs are generally apart and one's knees are bent such that a back of each said knee is engaged with an end of said force translation member;(d) swinging a golf club through an arc generally across the front of one's body such that the back of one of said knees moves in a first direction against one end of said force translation member to cause said force translation mem

Abstract: This invention relates to new bis(acyloxymethyl)imidazole derivatives; to compositions comprising these derivatives; and to processes for their utility as fungicides, bactericides and as inhibitors of the growth of cancer, particularly solid tumor cancer, in warm blooded animals of the formula: ##STR1## wherein M is ##STR2## or R; each R, R' and R" are independently selected from hydrogen and Z substituted or unsubstituted alkyl, cycloalkyl, cycloalkenyl, alkenyl, aryl, and heterocyclic ring wherein said ring comprises at least one of oxygen, nitrogen, sulfur or silicon; provided that ##STR3## may form a Z substituted or unsubstituted heterocyclic, and R' and R" attached to the imidazole ring, may form a Z substituted or unsubstituted heterocyclic ring; X is selected from at least one of oxygen, sulfur, nitrogen and alkyl; provided further that silicon is not directly attached to oxygen, sulfur or nitrogen and R' is not hydrogen when X is oxygen or sulfur; and Z is selected from halogen, nitro, nitrile, alkyl
