Abstract: A washing system for an elevated surface has a) a housing having a liquid application cleaning system therein; b) a support element that supports and elevates the washing system; c) a rigid member extending from a surface of the housing that faces away from a surface to be cleaned so that the cable, when supporting the cleaning system against the surface to be cleaned and connected to the housing at a connection point, exerts a rotational force on the cleaning system in relation to the fixed fulcrum at the roof top; and d) weights provided at a distance and direction from the connection point fulcrum to at least in part counterbalance the rotational force.

Abstract: A truck and trailer combination has a trailer removably mounted on the truck frame with longitudinal and horizontal channel members secured to the truck frame and longitudinal rails fastened to the trailer. The rails have a slide fit with respect to the channel members. Lock pins connect the rails to the channel members.

Abstract: A fish live box has a frame assembly supporting a mesh screen surrounding a chamber for accommodating fish. A top wall and door closes the top of the frame assembly. Brackets mount the live box to a dock. Upright legs mounted on the frame assembly are vertically adjustable to locate pads on the bottom of the legs on the bed of a body of water to support the box on the bottom of a body of water.

Abstract: A sight glass apparatus providing visual information concerning the presence of absence of liquid in a refrigeration system has a sight glass with a pair of clear glass bodies secure to a housing having a chamber for the liquid. The bodies have angled prismatic surfaces. One body includes a convex lenses that directs light to a colored member that reflects a colored toroid image when the chamber is full of liquid. A moisture sensing element is mounted on the sight glass to identify the presence of water in refrigeration and air conditioning systems.

Abstract: A vest for a human body has an air core coupled to a pulsator operable to subject the vest to pulses of air which applies and releases high frequency pressure forces to the body. The pulsator has two diaphragms connected to a brushless electric dc motor with rotary to reciprocating linear motion transmitting mechanisms comprising scotch yokes having anti-lash assemblies operable to generate air pulses in an air pulsing chamber. The diaphragms also increase the pressure in a manifold chamber. A check valve connects the manifold chamber with a pulsing chamber to allow pressurized air to flow from the manifold chamber into the pulsing chamber. An air flow control valve in communication with the manifold chamber is used to adjust the pressure of the air in the manifold and pulsing chambers. A programmable motor controller adjusts the duration of operation and speed of the motor to vary the operational time and frequency of the air pulses.

Abstract: A self powering portable case has a custom liner insert tray accommodating electric hair clippers and trimmers and detachable blades therefore. Retractable power cords attached to the hair tools are dispensed from cord holders to facilitate tool use. The cords are electrically coupled to a power connector that is connected to a electric power supply to power the tools.

Abstract: A ski lift for an airplane having skis has a body transversely rotated with a shaft on a ski and an axle secured to the body rotatably supporting a wheel. A bar secured to the body engages the ski to limit rotational movement of the body and locate the axle and wheel in engagement with a support surface laterally of the vertical plane of the shaft to retain the ski above the support surface. A handle is used to manually rotate the body and angularly move the axle and wheel.
