Abstract: An extendable support system for supporting an object on a surface, the support system comprising a support structure comprising an inner post and an outer post arranged such that the relative longitudinal position of the inner post and the outer post effects a change in an overall length of the support structure to vary the height of the object above the surface; a guide assembly comprising one or more guides positioned between the inner post and the outer post, the guides being configured to maintain the lateral position of the inner post and the outer post with respect to one another while allowing longitudinal movement of the inner post and outer post with respect to one another along the length of the support structure.

Abstract: A hydraulic foot assembly for supporting an object on a surface, the foot assembly comprising a cylinder defining an interior reservoir, a piston dividing the reservoir into two chambers in fluid communication with one another, the piston moveable within the reservoir, the position of the piston within the reservoir effecting the overall length of the foot assembly, a valve arrangement configured to limit movement of the piston within the reservoir.

Abstract: A water tap having a tap body, separate connections on the tap body for receiving supplies of hot water H, cold water C and further liquid F, a common discharge spout mounted on the tap body, and valves for controlling the supply of hot water H, cold water C and further liquid F from the tap body to the discharge spout, in which: the discharge spout is provided internally with two separate discharge passages which lead to a common discharge outlet; the tap body defines a route for hot water only which communicates with a first separate discharge passage in the discharge spout; the tap body also defines separate incoming routes for the cold water C and the further liquid F, and a common outgoing route for either the cold water C or further liquid F and such common outgoing route communicating with a second separate discharge passage.

Abstract: A water tap (10) having a tap body (11), separate connections (12, 13, 14) on the tap body (11) for receiving supplies of hot water H, cold water C and further liquid F, a common discharge spout (15) mounted on the tap body (11), and valves (20, 24, 25) for controlling the supply of hot water H, cold water C and filtered water F from the tap body (11) to the discharge spout (15), in which: the discharge spout (15) is provided internally with two separate discharge passages (16, 17) only which lead to a common discharge outlet (18) of the spout (15); the tap body (11) defines a route (19) for hot water only, under control of a hot water control valve (20), and which route (19) communicates with a dedicated first one (16) of the two separate discharge passages in the discharge spout (15) and which can therefore discharge hot water H only; the tap body (11) also defines a separate incoming route (21, 22) for each of the cold water C and the further liquid F, and a common outgoing route (23) for one or the other

Abstract: A door and a ceramic handle or knob assembly are disclosed. The ceramic handle has a socket extending from a rear end wall and into the body of the handle. A plastic insert is received in the socket, so that the handle may be secured to the door by means of a threaded bolt, passing into and expanding the plastic insert.

Abstract: A door and a ceramic handle or knob assembly are disclosed. The ceramic handle has a socket extending from a rear end wall and into the body of the handle. A plastics insert is received in the socket, so that the handle may be secured to the door, either by means of a conventional spindle or by means of a threaded bolt, passing through a hole in the door.

Abstract: A door having a releasable door lock is disclosed for use in e.g. a bathroom. The locking mechanism comprises a plate having a slot which in use is moved to surround the square section spindle and prevent its rotation. The plate is moved by means of a rotatable pin which includes a toothed wheel such that rotation of the wheel moves the plate and locks it in position. The door is releasable from the outside of the room in an emergency.
