Abstract: A foot 200 for attachment to a leg 180 of a trolley frame 100 designed to assist a user of reduced mobility move about a floor 120. The foot 200 has a first state in which the foot presents a contact surface 224 having a frictional resistance that facilitates slidable contact between the foot 200 and the floor 120 when attached to the leg 180 and when in use, and a second state in which the foot presents an enhanced contact surface 252 having an increased frictional resistance between the foot and the floor to resist said slidable contact. The foot 200 is transferrable between the first and the second states in dependence on a downwardly directed force 190 being exerted by the user on the foot through the leg of the trolley frame to allow the trolley frame 100 to be slid or to resist sliding depending upon the state of the foot.

Abstract: A solid fuel burning space heating appliance comprises a combustion chamber including front, side and rear walls, a top and a bottom. An apertured grate arrangement is provided in the combustion chamber for supporting solid fuel. An ash collecting region is located under the grate arrangement, with an air inlet for providing combustion air. A first air outlet in the combustion chamber is located below the grate arrangement, and a second air outlet in the combustion chamber is located above the grate arrangement. An air diverting arrangement is provided for selectively diverting air from the air inlet between the first and second air outlets. A glass cleaning system provides a vertical curtain of air over the interior surface of a glass panel. The glass cleaning system includes an air supply adjacent one side wall, an air reservoir connected to the air supply and a dam defining a tapered outlet slot for providing the curtain of air from the air reservoir.
