Abstract: An automated, self-service dry cleaning delivery system accepts and records items dropped off through a kiosk for cleaning, and returns cleaned items to the same kiosk for customer pick-up. A computer software program operates the conveyors, the loading doors, and material transporting equipment. To facilitate maximum customer satisfaction, numerous customer feedback choices are displayed to maximize system dexterity.

Abstract: Axially compressible, self-sealing, high bandwidth F-connectors for conventional hand tools for interconnection with coaxial cable. An internal, dual segment sealing grommet activated by compression provides a seal. Each connector has a rigid nut that is rotatably secured to a, tubular body. A rigid, conductive post coaxially extends through the connector. A post barbed end penetrates the cable within the connector. A tubular, metallic end cap is slidably fitted to a body shank, and thereafter forcibly compressed lengthwise during installation. The end cap has a ring groove for seating the enhanced grommet. The end cap can irreversibly assume any position, being held by end cap teeth. A tactile system comprising external convex projections on the body complemented by a resilient, external O-ring on the end cap aids installers who can properly position connectors with the sense of touch.

Abstract: A container comprises a knockdown carton made from a flat blank of corrugated material, and a knockdown lid. The carton comprises a center panel, foldable end panels, foldable side panels, and foldable corner panels. A pair of diametrically opposed corner panels are folded inwardly into contact with opposed end panels. The end panels comprise rectangular cutout holes surrounding foldable flaps. The lid has a central panel that is divided from integral end panels and integral side panels. A lid side panel extending vertically downwardly is coupled to the carton. Lid end panels have elliptical orifices that register with carton cutout regions and adjoining slots that align with handle anchor orifices. An alternative lid has flaps comprising major and minor segments separated by a diagonal fold line. The minor segment has an apex that releasably biases the flap in engagement with the end panel, yieldably locking the lid.

Abstract: A programmable liquid sampler for obtaining and digitally analyzing multiple, sequential samples in real time from an external source of liquid to be analyzed comprises an adaptive feedback algorithm for correcting sample weight measurements occasioned by vacuum delays. A sampling assembly receives and at least temporarily stores a sample drawn by suction through an air port that can also pressurize the chamber. A load cell determines sample mass through a logic controller that implements adaptive feedback by recognizing a desired target sample size, requesting an initial sample, and measuring the initial sample size. A variable scaling factor is derived by comparing the target sample size to said measured sample size and the subsequent requesting size is scaled. Samples can be stored in multiple compartments of a radial table that is indexed by the computer software for proper sample control.

Abstract: Coin operated vending machines and vending methods for self service car washes that vend different commodities or services at a united price. The machines vend vacuum at different speeds, and spot remover or fragrance. Each machine has a computer-controlled, multi-segmented bar graph providing an analog indication of the amount of a vend that remains, and a dot matrix system for displaying text messages. The bar graph has multiple adjacent segments each having multiple cells that contain separate LEDS of different colors. The bar graph provides a relative, analog indication of the amount of a particular commodity remaining to be vended. When a vend starts, all of the bar graph segments are illuminated and as vending continues, bar graph segments and individually cells are sequentially decremented. Different products are associated with different colors. The customer may switch selections while a credit balance remains, and bar graph illumination is reset to 100%.

Abstract: A training wheel assembly for standard bicycles comprises training wheels connected by resilient legs to a dynamic compression fitting. The wheels project generally rearwardly and outwardly apart from the bicycle rear. Adjustable mounting brackets enable wheel height to be varied. The dynamic compression fitting comprises an adjustable flange section mounted to the bicycle frame within the standard trapezoidal void to the rear of the crank sleeve. A pair of yoke segments can be slidably adjusted to accommodate varying dimensions. An intermediate flexing section resiliently coupled beneath the flange section receives ends of the legs and establishes an up and down pivot. A damper section connected beneath the intermediate section comprises a rigid, tubular sleeve that slidably receives a tubular cap. A resilient grommet coaxially confined between the sleeve and the cap is compressed by an elongated through bolt coaxially penetrating the compression fitting. The bolt establishes a radial pivot.

Abstract: A method and apparatus of preventing sunburn includes a forearm guard, which includes a first panel having a front edge, a rear edge, a first lateral edge and a second lateral edge. A coupler is attached to the first panel for selectively coupling an inner surface of the first panel to an outer surface of the first panel. The forearm guard is extended around a forearm and coupled thereto with the coupler. An upper armguard includes a second panel having an upper edge, a lower edge, a first side edge and a second side edge. A biasing member is attached to the second panel for biasing the first and second side edges toward each other. An arm may be extended between the biasing member and the second panel so that the upper armguard is positioned on a front portion of an upper arm.

Abstract: A high performance, multiple rotor, hydraulically driven riding trowel for finishing concrete includes a rigid trowel frame with two or more downwardly-projecting, bladed rotor assemblies that frictionally engage the concrete surface. The rotor assemblies are tilted with double acting hydraulic cylinders to effectuate steering and control. Double acting hydraulic cylinders also control blade pitch. Hydraulic pressure to the rotors is monitored and controlled by an unloader valve system that monitors drive pump pressure with a shuttle valve to derive an unloader pilot signal. A sequence valve responds to the unloader pilot signal to control a pressure valve that bypasses the normal foot control valve in an overpressure situation. The pressure control head signal normally applied to the hydraulic drive motor control heads is modified with a feedback signal to automatically control the associated pump swash plates.

Abstract: Screen separators and a screen tensioning system for separators that facilitates rapid measurement of screen tension. Each separator subframe screen is suspended between opposed subframe walls. Suitable linkages distribute vibration during the aggregate sifting process. Screen edge flanges are secured by tensioners that control a screen suspension bracket. A carriage bolt fitted through bracket orifices and the walls coaxially receive a resilient grommet captivated by an adjustable sleeve nut. As the nut is tightened, screen tension increases and the grommet diameter increases. A portable gauge with an internal U-shaped measurement sleeve is fitted over the deformed grommet to measure screen tension. A plurality of gauge calibration points bordering the deformed grommet determine applied screen tension.
