    Abstract: A conveyor having a belt and continuous bearing elements near the lateral edges of the belt to support the belt, in which there is means to supply fluid under pressure to the gaps between the bearing elements and the belt to form a fluid bearing for the belt. The bearing elements may have convex surfaces, and the belt may have cooperating concave surfaces of very slightly smaller concavity, whereby the gaps are narrowest at the edges of the bearing elements. Preferably, the bearing elements are hollow and there is means to supply pressurized fluid to the hollow elements, and thence to the gaps between the bearing elements and the belt.

    Abstract: 1,153,433. Endless conveyers. AJEM LABORATORIES Inc. 24 June, 1966 [8 July, 1965], No. 28546/66. Heading B8A. [Also in Division B1] An endless conveyer belt 10 is formed with guide rails 13 which are adapted to engage guide pulleys 15b, 15c, 15d thereby constraining the belt to a pre-determined path. The rails 13 are mounted on edging strips 14. The pulleys may be adjusted in a direction normal to the plane of the belt by screws (19), (Fig. 2, not shown); they may also be resiliently mounted. The rails may be of triangular, square, trapezoidal or half-round cross-section, the crosssection of the pulley rim conforming to this shape in each case. As applied to a mesh screen belt for a filtration unit (Fig. 8, not shown), (see Division B1) one guide pulley (72) is located near a drive drum (71) which bears the reaction of the pulleys (72). Another pulley (74) bears on a bearing surface (76).
