Abstract: An upholstery tool for use with a surface cleaning apparatus, the apparatus including a source of suction, wherein the tool includes a body including a dirty air inlet in a tool surface which faces a surface to be cleaned in use, wherein the dirty air inlet includes a first inlet section which extends across the surface and terminates in peripheral bleed air inlets a second inlet section which extends across the surface and terminates in peripheral bleed air inlets; and a third inlet section which fluidly connects the first and second inlet sections; and an outlet for fluid communication with the source of suction fluidly connected to the dirty air inlet.

Abstract: A surface treatment device includes a body and a treatment head for treatment of a surface wherein at least a part of the treatment head is detachable from the body of the device, and replaceable by a treatment head or part of a different configuration from that of the first head or part.

Abstract: The invention provides an automated workstation capable of continuous, non-stop processing of specimens. The workstation includes a storage area that holds multiple cassettes containing specimens compounds or other materials to be analyzed or used in conjunction therewith (collectively, “specimens”) which, preferably, are maintained on slides, microliter plates, or the like (collectively, “plates”). The workstation also includes a robotic arm for processing the specimens, e.g., by grasping the plates, moving them from the cassettes to other apparatus contained within the workstation, and placing the plates back in the cassettes. The invention also provides methods and apparatus for acquiring and processing samples in narrow, thin-walled pipettes without transferring them to wells, vials, or other reaction vessels.

Abstract: Solderable structures, and related methods for making them, can provide thermal conductivity and/or electrical isolation for electronic devices soldered to the structures. Each of the structures includes a solderable material bonded to a heat sink by a thermally-activated bonding material which provides thermal conductivity between the solderable material and the heat sink and which can be configured as a three-layer bonding film to also provide electrical isolation. The structures can be produced in a highly-automated, rapid way without the need for standard mounting hardware and mechanical preparation of the heat sinks.
