Abstract: A drying device for a wall structure includes an inflatable drying mat (1) of lightweight plastic sheeting and a floor engaging portion (2), a wall engaging portion (3), an outwardly facing portion (4) that extends between an outer edge portion (5) of the floor engaging portion (2) and an upper edge portion (6) of the wall engaging portion (3) to define a triangular cross-section when in use and connected to an air mover. In use of the drying device, a deflated mat (1) is laid on a floor and against a wall structure to be dried. The air mover is then powered up whereupon the mat (1) is deployed automatically against the wall to a height in excess of one meter without any outside assistance.

Abstract: The present invention provides a drying device for a wall structure, the device comprising an inflatable drying mat (1) of lightweight plastic sheeting and generally comprising a floor engaging portion (2), a wall engaging portion (3), an outwardly facing portion (4) that extends between an outer edge portion (5) of the floor engaging portion (2) and an upper edge portion (6) of the wall engaging portion (3) to define a triangular cross-section when in use and connected to an air mover. The drying mat 1 also comprising opposite end portions (7, 8) that closes the mat (1) to form an inflatable configuration when in use. The floor engaging portion (2) and the wall engaging portion (3) are both provided with a multiplicity of apertures whereby, when the mat (1) is deployed against a wall structure and an air mover is attached to the mat (1) air passes through the multiplicity of apertures to dry the wall structure.

Abstract: During each idle period in which a plasma processing tool is not used in succession, upon lapse of a selected period of inactivity by the plasma production tool of between 10 and 60 minutes, a plasma is generated within the plasma processing tool to heat the vacuum enclosure to an operating temperature reached during production use of the plasma processing tool. A gas-only purge is then performed, and the vacuum enclosure is pumped down to a base vacuum to remove small particles of less than 0.12 microns that may otherwise generate on the interior walls of the vacuum enclosure. Extended operation of the plasma processing tool without failure of particle qualification or reduced availability is achieved.

Abstract: Low power double heterojunction bipolar transistors with low parasitics, and methods for making the same is presented. A transistor is fabricated such that the collector region underneath a base contact area is deactivated. This results in a drastic reduction of the base-collector parasitic capacitance, Cbc. An embodiment of the present invention provides a transistor architecture for which the base contact area can be decoupled from the collector and hence allows for dramatic reduction in the parasitics of transistors.

Abstract: An electrical connector includes a window assembly including an electrically insulating transparent base and a plurality of electrically insulating transparent windows extending outwardly therefrom. The connector may include an electrically conducting body having spaced apart cable-receiving passageways for receiving respective insulation-free electrical cable ends therein, and with each cable-receiving passageway having a cable inlet opening and a cable end viewing opening opposite the cable inlet opening. The body may also have at least one respective fastener-receiving passageway intersecting each cable-receiving passageway. The individual windows of the window assembly are aligned with respective cable end viewing openings to provide a cover and to permit visual confirmation of proper placement of the insulation-free electrical cable end within a corresponding one of the cable-receiving passageways.

Abstract: High-density composite materials comprising tungsten and bronze are useful as lead replacements in the production of ammunition, weights and other high density articles. The composition of the composite, articles manufactured using the composite, and a process for making the composite are disclosed.

Abstract: A heterojunction bipolar transistor is presented, comprising a substrate having formed thereon a heterojunction bipolar transistor layer structure, and including an emitter layer. The emitter layer includes a strained, n-doped compound of indium arsenic and phosphorus. The transistor further comprises, between the substrate and emitter layer, a subcollector layer, a collector layer, a base layer, and an optional spacer layer. The emitter layer may include a graded portion. A contact layer is formed on the emitter layer to provide contacts for the device.

Abstract: A tubular article has an outer component of insulating material having a convoluted outer surface, and an inner component of stress grading material. In another embodiment, a tubular article has an outer component of insulating material having an outer surface that is convoluted along part of its length and shedded along another part of its length. The articles may be of heat-shrinkable polymeric material. The articles are particularly useful for terminating high voltage electric cables, and in the manufacture of electrical insulators.

Abstract: A system is disclosed which indicates a series of intermittent losses of fluid between any two stations along a fluid flow system such as a refinery or pipeline. The series of intermittent losses relates to a chain of intervals of operation of the fluid flow system. A sudden disturbance in the operation of the fluid flow system during an interval of operation is smoothed over a selectively variable number of intermittent loss indications in the series rather than reflected entirely in the intermittent loss indication for the interval of operation in which the sudden disturbance occurs. On the other hand, actual changes in the operation of the fluid flow system are averaged over the selectively variable number of intermittent loss indications in the series so that rapid changes as well as gradual changes in the operation of the fluid flow system result in a trend in the series of intermittent losses.

Abstract: An assembly for locking a hook to a board to prevent the hook from disengaging from the board wherein the hook has an offset board engaging portion, a shank portion having a straight board engaging portion extending at right angle thereto with a notch near the shank. The hook is held in frictional contact with the board by a locking clip having an opening traversed by the offset board engaging portion of the hook and a curved indentation engaged in the notch of the straight board engaging portion of the hook.
