Abstract: A garment hanger has a body (1) with a longitudinal axis. A movable first arm (2) is slidably mounted on the body for free movement with respect to the body substantially along the longitudinal axis. A constant or decreasing force spring (4) applies a resilient force to the first arm to urge the first arm outwards of the body so that the first arm is able to move between a retracted position and an extended position relative to the body. The resilient force exerted by the garment hanger remains substantially constant or increases between a fully retracted position and a fully extended position.

Abstract: Inkjet printing apparatus for use with radiation curable ink includes a sensor for sensing the amount of radiation emitted by a source of radiation. A controller is connected to the sensor and is operable to vary the amount of radiation emitted by the radiation source in accordance with a signal received from the sensor. A drive mechanism moves the source of radiation to a location laterally offset from the substrate where the sensor is positioned.

Abstract: A wound therapy combination comprising a suction head and a surgical drape. The suction head comprises a planar flange portion and a tubular connector piece on a first face that communicates with an aperture extending to a second face. The second face is formed with projections that define flow channels for facilitating flow of liquids to the aperture.

Abstract: An advertising ski paraphernalia basket is securely mounted in non-rotatable relation to a safety bar of a chair ski lift. The basket includes one or more surfaces on which is placed indicia, usually advertising. The advertising is preferably replaceable, making the basket a site for third party paid advertising exposed to a captive audience that produces a continuing revenue source. The chair ski lift safety bar is moveable in an arcuate path between a passenger safety position whereat the safety bar is disposed forwardly of an apex balance point in blocking relation in front of the chair portion of the chair ski lift, and an entry-exit position whereat the safety bar is disposed above and rearwardly of the chair portion of the chair ski lift and rearwardly of the apex balance point. The basket comprises a floor suitable for receiving ski paraphernalia, and walls extending upwardly from the floor about the periphery thereof.

Abstract: An enclosure for an electronics assembly, comprises (i) a housing (1) having a recess (36); and (ii) a module (40) for holding one or more components of the assembly, the module being insertable into the recess by sliding, and removable therefrom by sliding in a direction opposite to the direction of insertion; and (iii) a spring retaining element (48) located in one of the housing and the module, the element being in the form of a resiliently deformable arm that engages the other of the housing and the module when the module is inserted into position within the recess in order to prevent removal of the module from the recess. The arm can be manually bent to release the module from the recess, but the housing or the module allows a degree of movement of the retaining element during release of the module that is insufficient to allow the arm to bend beyond its elastic limit. The enclosure enables the module to be held firmly in place, but allows quick and easy release for maintenance of the assembly.

Abstract: A system for stimulating the healing of tissue comprises a porous pad positioned within a wound cavity, and an airtight dressing secured over the pad, so as to provide an airtight seal to the wound cavity. A proximal end of a conduit is connectable to the dressing. A distal end of the conduit is connectable to a negative pressure source, which may be an electric pump housed within a portable housing, or wall suction. A canister is positioned along the conduit to retain exudates suctioned from the wound site during the application of negative pressure. A first hydrophobic filter is positioned at an opening of the canister to detect a canister full condition. A second hydrophobic filter is positioned between the first filter and the negative pressure source to prevent contamination of the non-disposable portion of the system by exudates being drawn from the wound. An odor filter is positioned between the between the first and second hydrophobic filters to aid in the reduction of malodorous vapors.
