Abstract: ABSTRACT               SUSPENSION ASSEMBLY FOR A WHEEL AND BRAKE   A suspension assembly couples a wheel assembly (16) and a brake assembly (60) to a frame (10).  The suspension assembly includes a support (20) for receiving an axle (24).  The axle carries the wheel assembly (16) at one end of the support (20) and forms a drum (46) at the other end of the support (20) for engagement with the brake as-sembly (60).  Therefore, the support (20) separates the wheel assembly (16) from the brake assembly (60) so that the brake assembly (60) brakes the wheel assembly (16) vic the axle (24).

Abstract: ABSTRACT            An inspection device detects flooding in a hollow structural member such as the leg of an oil or gas rig so as to detect the presence of through wall cracks in the member.  The device comprises an ultrasonic transducer for transmitting a pulsed beam of ultrasonic sound to pass through opposing faced walls or wall portions of the member and a visual indicator responsive to time spaced echoes of the ultrasonic beam reflected respectively from the opposing walls or wall portions and received by the transducer to indicate the presence or absence of flooding in the member.  The transducer is located in the bridge plate of a jig and its beam passes through an aperture in a support frame of the jig.  The support frame has a pair of spaced magnetic feet attached to a bracket on the frame and a further magnetic foot secured to the frame, the feet permitting the jig to be clamped onto a steel rig member so that the transducer can be optimally aligned with the member to optimise received echoes.  The bridge plate is movable in two orthogonal planes by adjusting control knobs so as to optimise alignment.  A further visual indicator also  responsive to the echoes from the transducer is adjustable to indicate whether the transducer is optimally aligned and only when the transducer is optimally aligned is the presence of flooding, if indicated by the indicator, taken to be valid.

Abstract: WEARING APPAREL AND METHODS FOR THE MANUFACTURE   OF WEARING APPAREL            ABSTRACT OF THE DISCLOSURE     Methods are provided for producing protective and useful wearing apparel, such as work gloves, work boots and aprons,  and wearing apparel so produced by such methods.  The methods include joining a non-woven fi-brous web, such as needled felt to a knitted web, such as a knitted jersey, and utilizing a needled staple fiber preferably from the non-woven web to join the two webs together into a formed laminate.  The joining pro-cedure is such that the finished laminate includes the needled staple fiber extending from one surface of the web to form a base surface for a subsequent applica-tion of an elastomeric coating.  The resulting coated surface is textured to provide a gripping surface, for example, for use in gloves to handle smooth surfaced items with sharp edges, such as glass.  The remaining exposed non-woven fibrous web surface forms  a soft protective internal surface for the wearing apparel such as gloves or boots.  The outer coating may be liquid impervious, or it may be permeable in order to provide a fabric laminate which is "breathable".

Abstract: Abstract of the Disclosure This invention relates to a ridge tile which defines a ventilating gap between the outside surface of that end portion of the tile which is over-lapped in the roof and the inside surface of the over-lapping end portion Or the adjacent ridge tile in that its end portion which is overlapped in the roof has a flat surface and the lower portions of the outside surface of its overlapped end portion define a clearance with the inside surface of the overlapping end portion of the adjacent ridge title. It is an object of the invention to provide a ventilating ridge tile which is of the kind defined first hereinbefore and together with an adjacent ventilating ridge tile of the same kind defines a larger effective ventilating cross-sectional area whereas the external size and shape of the ventilating ridge tile are substantially pre-served and the universal usability of the ventilating ridge time in a mortar bed or with unbonded joints on roof pane tiles or ridge-adjoining tiles is ob-structed or reduced.  This is accomplished in that the overlapped end portion of the ridge tile is provided with additional, outwardly sloping, flat surfaces between the surface at the apex of the tile and those portions which define a clearance with the adjacent ridge tile.

Abstract: ABSTRACT      Treatment of oxidic materials In the fluidised bed chlorination of oxidic materials, for example minerals such as bauxite, tantalite, columbite, wolframite or scheelite, the separation of metal values giving vaporous chlorides at the reaction temperature is enhanced by maintaining a zone substantially free of chlorine in the fluidised bed, for example a zone at least 0.25m in depth measured from the expanded bed surface.  A high aspect ratio bed and counter current movement of the bed matter and the chlorine within the bed are preferably used.
