Abstract: This disclosure relates to mopping trolleys and has particular reference to mopping trolleys for facilitating the cleaning of a floor area. According to one aspect of the present invention there is provided a mopping trolley comprising carriage means capable of translation movement over a surface, a mop press assembly carried by said carriage means for expressing liquid from a mop head inserted into the press and at least two liquid receptacles, wherein a waste receptacle is arranged to receive waste liquid expressed from the mop press, and a clean receptacle is for providing a source of clean liquid for use in mopping.

Abstract: According to the present invention there is provided an electrical appliance having a releasable cable connector for electrically connecting the appliance to a remote power supply, wherein a first junction means is adapted to provide the releasable electrical connection between the cable connector and the appliance, characterised by the provision of a second junction means adapted to provide a non-releasable, hard-wired electrical connection between an alternative cable connector and the appliance, wherein the first junction means and the second junction means are arranged and configured so that the selection and use of one of said junctions by attachment of one cable connector precludes the simultaneous selection of the other connector.

Abstract: The disclosure relates to the floor scrubbing or finishing machines. There is provided a machine for scrubbing or finishing a floor surface comprising carriage means adapted for translational movement over a floor surface, a workhead, an electric motor carried by the carriage means and arranged in use to drive the workhead and battery support means adapted in use to support at least one battery as a source of electric power for driving the electric motor, wherein said battery support means are adapted to support said at least one battery so that said at least one battery can be positioned in a selected one of a range of positions relative to said workhead whereby the loading on said workhead can be varied as required.

Abstract: Methods and apparatus are described for marine asset security and tracking (MAST). A method includes transmitting identification data, location data and environmental state sensor data from a radio frequency tag. An apparatus includes a radio frequency tag that transmits identification data, location data and environmental state sensor data. Another method includes transmitting identification data and location data from a radio frequency tag using hybrid spread-spectrum modulation. Another apparatus includes a radio frequency tag that transmits both identification data and location data using hybrid spread-spectrum modulation.

Abstract: A method is disclosed for reducing sag in drilling and completion fluids and in workover fluids. The method employs a drilling fluid comprising a low molecular weight polyalkyl methacrylate with an average molecular weight ranging from about 40,000 to about 90,000. This additive does not result in increased viscosity of the fluid.
