Abstract: ABSTRACT       The invention is concerned with hydrostatic bearing arrangements in which there is a fluid-flow control valve which is adapted to exercise an automatic pressure responsive control over two fluid-flow outputs to a pair of bearings.          The fluid-flow control valve has a deflectable valve member located between two control surfaces so that a fluid-flow restriction is formed between the valve member and each of the two control surfaces, whereby movement of the valve member in a direction to close one of the restrictions opens the other restriction and vice versa, there being a fluid supply port opening through one of the two control surfaces into the restriction between that surface and the valve member.          There may be a communicating port through the valve member and a single supply port communicating directly with one of the restrictions and communicating indirectly with the other restriction through the communicating port.  As an alternative to the communicating port, the valve may have a conduit by-passing the valve member.     In a preferred arrangement, a valve assembly comprises two or more fluid-flow control valves each in accordance with the invention combined in a stack, with a single inlet passage communicating with an inlet port in each of the valves. There may for example be a manifold block, the inlet passage being formed in the manifold block, and the valves being mounted on the block.     The invention also comprises a hydrostatic bearing arrangement for a machine in which there are two hydrostatic bearings and a control valve of the kind referred to, arranged so that the fluid supply to the bearings passes through respective ones of the two fluid-flow restrictions, the two bearings being mounted on the first of a pair of relatively movable members in a machine and the two bearings acting on oppositely facing surfaces of the second of the relatively movable members, the arrangement providing that if the relatively movable members tend to approach each other so as to narrow the clearance at one of the bearings and to increase it at the other bearing, the resultant increase in fluid pressure at the bearing where the clearance tends to narrow causes movement of the valve member whereby the fluid supply from the valve to the bearings is varied so as to exercise a control on the location of the second relatively movable member with respect to the first relatively movable member.   - 1a -

Abstract: ABSTRACT OF THE DISCLOSURE Dewaxing aid used in a solvent dewaxing process is recovered in wax bottoms from slack wax by vacuum distilling the slack wax to about 5-10 wt. % bottoms at a temperature no greater than about 320°C.  The dewaxing aid-containing wax bottoms is recycled back into the dewaxing process by adding same to the wax containing oil feed in an amount ranging from about 0.5-5 wt.%.  This has been found to be particularly advantageous when the dewaxing aid is an .alpha.-olefin copolymer, a chlorinated paraffin/naphthalene condensation product and mixture thereof because of their thermal stability.

Abstract: ABSTRACT OF THE DISCLOSURE     A rail construction for mounting and tensioning an electrically heated screen on and between a pair of longitudi-nally extending, spaced frame members.  The rail preferably is formed as an aluminum extrusion having a relatively large metal mass in cross section.  The rail has a modified channel shape in cross section with an upper curved flange, a lower angled flange and an intervening projection.  The upper curved flange is enclosed with electrical insulation and is adapted to en-gage a vertical wall of one of the frame members when mounted thereon.  The lower angled flange has a hook shape complementary to a hook shape formed on the edge of the screen cloth.  The intervening projection forms a wedge-shaped channel in combi-nation with the lower hook-shaped flange of the rail.  The wedge-shaped channel has an angled surface against which a complemen-tary wedge-shaped clamping bar clamps the hooked screen edge.          A series of bolts extending through the rail from the outside surface clamp the wedge bar, and interposed hooked screen edge, against the angled surface of the wedge-shaped channel.  A plurality of bolts extend through the rail and are engageable with a vertical wall of the frame member and are adapted to draw the rail toward the wall to tension the screen which is clamped to the rail by the wedge bar.  Electrical insulators are mounted on the rail bolts, and are located between the frame member and bottom of the rail to electrically insulate the rail from its associated frame member.  One or both surfaces of the opposed clamping surfaces of the wedge bar and wedge-shape channel may be serrated to provide increased gripping contact between the wedge clamp and the screen edge.
