Abstract: The invention relates to a device for detecting contact of a tool (2a, 2b) with an electrical conductor (5b) encased by an electrical insulation (5a). In order to ensure a reliable, robust and simple display of the tool-conductor contact for potential-free and short cable lengths, the tool (2a, 2b) consisting of an electrically conductive material is fastened to a tool holder (1a; 1b) made of electrically conductive material. A thin electrical insulation is provided between tool (2a, 2b) and tool holder (1a, 1b) so that these components together with the coaxial cable form a capacitor (CS). An inductance (La; Lb) is connected parallel to this so that a high-Q LC resonant circuit is formed between tool and tool holder. The electronic circuit arrangement excites the resonant circuit and determines characteristic oscillation parameters of this resonant circuit.

Abstract: A central vacuum cleaning system includes a locking collar mounted at various locations in a structure or RV and connected to the inlet end of a vacuum conduit. A section of hose is slidably mounted within the conduit and extends therefrom for cleaning an adjacent area. A pair of O-rings within the collar frictionally retains a handle mounted on the end of the hose in a stored position when the hose is in a retracted position and provides an air seal between the handle and vacuum supply conduit. A locking mechanism mounted on the collar automatically locks the hose in a selected extended position when manually pulled from the collar by a locking finger engaging an adjacent section of the hose. An electric switch on the collar enables a user to actuate the vacuum supply source. A mounting bracket enables the collar to be mounted at various locations in the structure and a ring formed on the collar enables the collar to be rotated to a desired position on the mounting bracket.

A handle and yoke distinct from, and behind, the base provides a moment arm anterior to the base when a force is applied. The handle and yoke assembly reduce the friction between the cleaning surface and the vacuum, allowing for larger motor and debris capturing capabilities, with easier handling and maneuverability resulting in advanced and superior cleaning capabilities.

Abstract: A vacuuming device for neutralizing flammable powders. The device includes a container having an upper chamber and a lower chamber separated by a baffle, with the upper chamber being in fluid communication with the lower chamber proximate an outer annular region of baffle. A liquid such as water is disposed in the lower chamber, and an air jet drawn into the lower chamber via a vacuum inlet line. In one embodiment, the air jet passes through the liquid for generation of a tangential flow that causes the body of liquid to rotate within the lower chamber. The rotation in the lower chamber can also cause the air in the upper chamber to rotate, so that liquid droplets entrained therein migrate to the outer wall centrifugally. Flammable particles entrained in the air jet are wetted and neutralized.

Abstract: A tool for a vacuum cleaner that comprises a nozzle and a bristle assembly. A suction opening is provided in the base of the nozzle, which extends from a front to a rear of the nozzle. The bristle assembly is mounted within the nozzle and protrudes through the suction opening. The suction opening is delimited along its length by a leading edge and a trailing edge, and at least part of the leading edge is raised relative to a front end and a rear end of the nozzle. Consequently, when the tool is swept over a cleaning surface and the front end and the rear end of the nozzle contact the cleaning surface, a gap is created between the cleaning surface and the leading edge.
