  • Patent number: 10113738
    Abstract: An underwater wall mounted light fitting having a sealed light source chamber and an electrical supply connection chamber including a port to sealingly engage over an electrical supply line with an array of electrical conductive connectors embedded in a dividing wall and each providing a connection terminal on opposite sides of the wall within the chambers respectively. The dividing wall is moulded around the connectors which are provided as rigid spigots with circumferential grooves to receive the moulded wall material. The connection chamber is a hollow cover with the port which includes a compression gland assembly for an electrical supply line. The dividing wall is securable against a peripheral frame provided on the lens and the frame includes a continuous flange which fits around the dividing wall. The housing is releasably securable to a wall mountable bracket. LEDs provide the light source.

  • Publication number: 20170321442
    Abstract: The invention relates to a drive mechanism for a pool cleaner (101). Rotation from a turbine assembly (201) is transmitted to a pair of rear wheels. A first wheel (104.1) is forwardly driven. The second wheel (104.2) is switch between corresponding forward rotation and rearward rotation. An axle (109) of the first wheel (104.1) includes a coaxial shaft which rotatably supports a sleeve that carries the second wheel (104.2). The reverse transmission is effected by a double-sided dog clutch member (117) slidably between a pair of clutch gears (118, 119) freely rotatable on a rotating lay shaft (111).

  • Patent number: 6474404
    Abstract: The invention relates to a method for controlling the temperature of a melt (10), preferably of a steel melt, in a distributing vessel (11), whereby the temperature of the melt is measured, the measured result is compared with a predetermined temperature range in the form of specified values, and as much heat is supplied or withdrawn from the melt such that the temperature remains inside said range. In order to control the melt temperature, a fireproof shaped part (20) which is closed on both sides and which is provided for accommodating a liquid cooled induction coil (1) is immersed in the melt (10). The transmission of heat is carried out by means of thermal conduction out of the wall of the shaped part (20) which is coupled to the induced electromagnetic field and/or by means of a direct coupling to the liquid melt (10).

  • Patent number: 5230582
    Abstract: A highway divider including a plurality of housing-like steel divider members which are releasably connected to each other in longitudinal direction. Each divider member has two side walls arranged in a mirror-inverted configuration. Each side wall includes a lower longitudinal strip member, a center longitudinal strip member and an upper longitudinal strip member which are connected to each other through concave portions so as to prevent buckling. Transverse wall members which are I-shaped in cross-section and have bottom surfaces are welded to the side walls on the vertical level of the lower longitudinal strip members and of the lower concave portions. In addition, horizontally extending stiffening plates can be welded between the side walls on the vertical level of the upper sides of the transverse wall members and the vertically middle portion of the center longitudinal strip members. Two successive divider members are connected through shaped pieces, connecting plates and threaded bolts.

  • Patent number: 5096179
    Abstract: A sheet feeder for the supplying of stream of single sheets to a sheet-processing machine. Preferably, a pile of sheets is carried by a pile table to a sheet-singling apparatus. The sheet-singling apparatus transfers a continuous stream of individual sheets, via a conveying table, to the sheet-processing machine. The invention allows for an extension of the time for changing the pile of sheets, due to the fact that a pile of sheets is provided on either side of the machine.

  • Patent number: 4741797
    Abstract: Apparatus is provided in which a support table and clamp arrangement serve to hold a panel in position while a surfacing sheet already applied to the major face of such panel, is applied around radiused edges of the panel. The apparatus includes a turntable to support a panel in raised position relative to the support table when the turntable is being rotated to enable successive edges of the panel to be presented to the apparatus without removing a panel from the turntable. The turntable can be located on a carrier movable laterally towards and away from the clamping arrangement.

  • Patent number: 4539065
    Abstract: Apparatus for applying a surfacing sheet such as a plastic sheet, veneer or the like to an optionally radiused edge of a panel, or to a column or the like, in which an applicator bar which is, optionally heated and is preferably flat, is urged against the surfacing sheet to press it onto the surface of the panel column or the like. Means are provided for ensuring that lateral movement of the applicator bar takes place relative to the panel or column to stretch and smooth the surfacing sheet onto the surface of the panel or column. The applicator bar is preferably carried on an arm arrangement held between two spaced rotatable end supports and the biasing is carried out by a number of spaced pneumatic or hydraulic piston and cylinder assemblies acting transverse to the arm arrangement. The biasing means is preferably carried on a frame member carried by the rotatable end supports.
