A floor cleaning device (1) comprises a housing (2) having an underside, at least one substantially disc-shaped brush being arranged on the underside of the housing. The disc-shaped brush can rotate and acts in a working surface. The device (1) also comprises a drive motor (4) for driving the brush, which drive motor (4) is coupled to the disc-shaped brush via a transmission. The disc-shaped brush is accomodated in a brush space, which brush space is delimited at the top by the underside of the housing (2), during use is delimited at the bottom by the workins surface and is delimited all the way around by an annular brush (10), the underside of which rests on the working surface during use. The annular brush (10) is provided with steam-feed means for feeding steam to the brush space.

A connecting assembly for connecting a C-shaped profiled-section element to another element comprises a connecting element and at least one coupling assembly (1) for coupling a C-shaped profiled-section element to the connecting element. The coupling assembly (1) comprises a plate-like connecting part (11) with two projections (16, 17), a connecting bolt (15) which fits through a bore in the connecting part (11), and an elongate nut element (22), which is pressed towards the connecting part (11) by the force of a spring acting on the connecting bolt (15). The two projections (16, 17) are positioned at a distance from one another which is such and the sides of the projections which face one another are shaped in such a manner that, in the situation in which the longitudinal centre axis of the nut element (22) substantially coincides with the centre axis of the projections (16, 17), the nut element (22) bears against the connecting part (11) and is retained between the projections (16, 17) in such a manner that it is locked against rotation.

An expansion tank (1) which is intended to be connected to a pipe system which is filled or is to be filled with a liquid, comprises a closed tank (2) with at least one connection opening (3) for a liquid pipe. The tank (2) is provided with a main valve (51) inside the tank (2) having a valve seat ((52) and a closure member (53) and being designed to close off the connection opening (3) at a defined difference between the pressure in the interior of the tank (2) and the pressure in the connection opening (3) and/or at a defined liquid level (57) in the tank (2). The tank (2) is further provided with an additional valve (71) for closing off a channel or passage (72) extending through the closure member (53) of the main valve from the interior of the tank (2) to the connection opening (3). The additional valve (71) is closed during normal operation of the expansion tank (1) when connected to a pipe system filled with liquid and is open if the difference between the pressure in the interior of the tank (2) and the pressure the connection opening (3) is higher than the original pressure in the expansion tank (1) when it was delivered ex works.
摘要:
An implantable textile prosthesis which is anatomically curved to substantially match the natural curvature of the aortic arch in a human being or patient is provided. The first woven section is arched define an apical region and to conform generally to an aortic arch of a human patient. A plurality of elongate woven tubular extents extend vertically from a top wall portion at the apical region of the tubular main wall. These tubular extents are sutured to the first woven section to provide fluid communication between the tubular main wall and the tubular extents.

A sheet structure obtained by separately producing an artificial leather base material and a leather-like skin, and combining the two together in simple equipment. An artificial leather having air permeability is produced as follows. A film material is filled in concavities of a transfer sheet having a convexo-concave shape reverse to a leather-like convexo-concave surface to form a perforated film layer. On the perforated film layer is formed a porous layer formed of open-cell foam. The porous layer is formed by coating an aqueous polyurethane dispersion solution containing base resin, which is foamed through agitation, followed by drying. The resultant sheet structure is thermally laminated on a desired base material. The base material is composed of a nonwoven fabric, a woven fabric, a knit, or the like, impregnated with foamed polyurethane as necessary. A thermally-fused open-cell foamed layer may additionally be formed on the porous layer to enhance flexibility and peeling strength, Lastly, the transfer sheet is peeled off.

A connection between an axle body (1) of a vehicle and a carrier arm (2), which extends in the longitudinal direction of the vehicle and crosses the axle body (1) substantially at right angles, the axle body (1) being substantially round in cross section, comprises a support part (3), which is positioned between the axle body (1) and the carrier arm (2) and has a recess (5) which accommodates part of the axle body (1), and also clamping means (4, 10), by means of which the support part (3) and that part of the axle body (1) which it accommodates are fixed to the carrier arm (2). At the location of the support part (3), the axle body (1) is provided with at least one projection (11) welded to the axle body, and in the recess (5) the support part (3) is provided with at least one depression (12) which is substantially complementary with respect to the projection, the projection (11), in the assembled state, being at least partially accommodated inside the depression (12).
摘要:
A wiring duct assembly including a duct base (10) and cover for supporting wire and/or optical cable therein, defining a latching mechanism (100) located on both the cover (40) and duct base (10). The latching mechanism (100) on the duct portion includes an inwardly projecting sidewall portion, a lip (27) attached thereto and a projecting tip potion (23) integrally attached to the lip. The sidewall, lip and tip define a groove (31) for receiving the latching mechanism (100) of the cover. The cover (40) includes two opposing side walls (46) wherein each side wall includes an inwardly extending portion for being received by a corresponding duct groove (31). The latching mechanism (100) for the cover portion further includes protuberances (48) in the interior surface of the cover (40) for securing the tip portion of the duct side wall to provide secure latching of the cover and duct base during shipping, installation, and completion of assembly.
摘要:
The invention relates to a device for administering a treatment fluid, in particular a chemtherapeutic agent, to an organ comprising at least one inlet vein and on outlet vein, which device comprises: - first closing means for closing the at least one inlet vein; - second closing means for closing the at least one outlet vein; - feed means for feeding the treatment fluid to the organ; - drain means for draining the treatment fluid from the organ; - a reservoir for storing the treatment fluid; and - pumping means for pumping the treatment fluid from the reservoir via the feed means into the organ and out of the organ again via the drain means.
摘要:
A composite intraluminal prosthesis which is preferably used as a vascular prothesis includes a layer of ePTFE and a layer of textile material which are secured together by an elastomeric bonding agent. The ePTFE layer includes a porous microstructure defined by nodes interconnected by fibrils. The adhesive bonding agent is preferably applied in solution so that the bonding agent enters the pores of the microstructure of the ePTFE. This helps secure the textile layer to the ePTFE layer.
