A cleaning vehicle comprises a rolling chassis and a primary power source (13) in the form of a combustion engine which is able and configured to drive the vehicle. A suction installation (30) is provided which has an underpressure chamber (20) and a pump device (31,32,33) coupled thereto. The pump device comprises a primary pump unit (31,32) which draws its input power from the primary power source (13). In addition, the pump device comprises a secondary pump unit (33) which is optionally driven directly by a secondary power source in the form of an electric motor. The secondary power source (33) is supplied independently of the primary power source (13) by an electrical power supply.

System for preventing the leakage of liquid from an outdoor work-site around the perimeter of the work-site includes a load-supporting surface having at least two adjacent mats and a plurality of berm members configured to be disposed around the perimeter of the load-supporting surface.

An aerodrome maintenance apparatus for monitoring runway and taxiway conditions and remotely reporting the status of the runway or taxiway. The apparatus comprises a drive unit operable to provide self-controlled rolling movement of the apparatus along a surface of a runway or taxiway of the aerodrome, a detection unit comprising one or more sensors configured to detect one or more parameters of the surface, and a communications unit comprising a transceiver arranged to transfer data derived from the detection unit from the apparatus to a remote server. The apparatus is arranged, in use, to move along the surface and transfer data representative of one or more parameters of the surface to a remote server.

The invention relates to a vacuum installation for industrial application, the installation comprising a first vessel having a first gas inlet for allowing a gaseous substance into the first vessel and a first outlet for depletion of a material, a second vessel having a second inlet for aspirating a quantity of material and a second gas outlet for depletion of the gaseous substance, wherein the gaseous substance comprises a vapour generated from the material, a storage chamber for storing the quantity of material, the storage chamber having a third inlet, wherein at least the first vessel communicates with an interior of the storage chamber via the first outlet and the third inlet; and a vacuum pump located in between the first vessel and the second vessel, and operated to lower the pressure in the second vessel, thereby allowing the material to be sucked into the second vessel via the second liquid inlet to an equilibrium level between the material and the gaseous substance, the vacuum pump being further operated to transport the gaseous substance to the first vessel to raise the pressure in the first vessel, thereby forcing the material in the first vessel into the storage chamber.

A collection kit for the removal of unwanted material from a surface, said kit comprising: iv) ferromagnetic material to absorb and/or adsorb the unwanted material when spread across the unwanted material creating an area of operation; v) an apparatus having a magnetic source operable to attract the ferromagnetic material together with absorbed and/or adsorbed unwanted material when the magnetic source is touching or in the vicinity of the area of operation; and vi) means to dislodge the ferromagnetic material and absorbed and/or adsorbed unwanted material from the apparatus once the ferromagnetic material has been removed from the area of operation.

The absorbent spreader is the only product of its kind that is specifically designed to make spreading maintenance absorbents a cleaner and faster task, saving consumers time and energy usually spent from traditional methods. The absorbent spreader is uniquely designed with a release button enabling users to precisely control where to drop the clay, ensuring no accidental messes or unnecessary waste of clay during task work.

Methods of containing liquid introduced onto a support surface include forming the support surface with at least two mats, the mats forming a perimeter of the support surface. A plurality of berm members is positioned at least partially around or proximate to the perimeter of the support surface and extends upwardly relative to the mats sufficient to prevent liquid introduced onto the top of the support surface from leaking off of the support surface around the perimeter thereof.

Disclosed is a device for absorbing and marking a potentially dangerous substance on the ground, the device including: an elongate hollow body, the inner walls of which define a storage space in which a powder is stored which is capable of absorbing the substance when the powder comes into contact with the substance, the storage space leading into an opening for pouring the powder onto the substance in order to neutralize the substance, a base on which the lower end of the body is directly or indirectly mounted, the base projecting laterally relative to the body so as to form a marker in order to position the device on the ground in a stable manner and to mark the presence of the absorbed substance on the ground.
