Abstract: A telescopic tanker for carrying fluid which has a wheel-mounted, extendible chassis with a first tank section and at least one other tank section that is telescopingly received within the first section. The tank sections are movable between their telescoped and untelescoped positions, and the tanker is adapted to be attached to a towing vehicle.

Abstract: A tracked vehicle to receive a wheeled vehicle and to be driven by the wheeled vehicle. The tracked vehicle has a chassis. Guide wheels are mounted on the chassis at each side and drive wheels mounted at at least the rear of the chassis, at each side. A track at each side of the vehicle is driven by the driven wheels and guided by the guide wheels. Drive members are attached to each drive wheel to receive a drive transmission. The chassis can receive and retain the wheeled vehicle further drive members are attachable to the driven wheels of the wheeled vehicle to receive the drive transmission so that driving of the driven wheels of the wheeled vehicle drives the tracks of the tracked vehicle.

Abstract: A container able to be moved from a raised position to a folded position. The container has a base and a roof spaced. First members are pivotally attached to the base and extend upwardly when the container is raised. Second members are pivotally attached at one end to the roof and each pivotally attached at its other end to a first member. Upper side panels extend between the roof and a pair of second members. Lower side panels extend between the base and a pair of first members. Reciprocable locking members can move from a first position at which they lock the first and second members in the raised position to a second position in which they allow pivoting of the first and second members. The locking members may be moved as required.

Abstract: A greenhouse comprising walls defining an area. A roof covers a portion of the area. Track means are interposed between the roof and the walls so that the roof may be moved along the track to cover a selected part of the area.

Abstract: A tool having a housing with a plurality of bits located within the housing. Each bit has a working end to protrude from the housing and an inner end in the housing. There is a pathway in each bit adjacent the inner end. An opening in the housing allows a bit to protrude. That bit can be gripped to hold it in place. Second openings are positioned in the housing and shafts extending through each second opening and through a pathway in a bit. Each bit is urged radially outwardly, for example by a spring. A bit may be selected by pushing on its shaft and moving the shaft downwardly towards the opening. The bit is then gripped in place with its working end protruding from the opening in the housing.
