Abstract: POWER STEERING PUMP     Abstract of the Disclosure:   A pump comprises a housing having an inlet and an outlet.  The housing defines a pumping chamber and pumping means is located in the chamber and is operable to pump fluid from the inlet to the outlet.  The pumping means includes pumping elements which define a series of pumping pockets which expand and contract to effect pumping of fluid.          A cheek plate having one axial side adjacent to and facing the pumping means is supported  in the housing.  The cheek plate has a sealing position blocking fluid communication between the pumping pockets and is movable therefrom to enable fluid to flow directly between the pockets.  The housing defines a cavity on the other axial side of the cheek plate.  A fluid passage di-rects a flow of fluid from the pumping means into the cavity for urging said cheek plate into sealing position.  A seal is provided between the cheek plate and the housing blocking flow into the cavity.  An orifice is located in the pump outlet.  A valve means is provided for venting the fluid pressure in the cavity to enable the cheek plate to move away from the pumping means to bypass fluid from the pump outlet to the inlet across the cheek plate.  The valve means includes a movable valve member having surfaces acted upon by fluid pressures on opposite sides of the orifice and which is movable in response  to changes in the forces acting thereon to control the pressure in the cavity to control the position of the cheek plate.  The valve member is stabilized by a fluid flow therepast which flow is established after initial movement of the valve member which effects venting of the cavity.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention provides an apparatus for feeding trees in their longitudinal direction into a processor along the treatment line.  The apparatus may be used for lopping, measuring, spray-protecting, cutting, sorting, or any other corresponding operation.  The apparatus comprises two feeding rolls or rollers provided with surfaces of sufficient adhesive capacity.  The feeding rolls are arranged above and underneath the feeding line of the trees and are mounted on substantially horizontal axles each of them at an arm of its own.  The arms are pivotable in the vertical direction and are fastened, by means of articulated joints, at a vertical distance from each other, to the frame of the treatment line.  A cylinder-piston apparatus is arranged between the arms of the feeding rolls and produces the compression force required by the feeding rolls  and guarantees continuous drive by both feeding rolls.  The upper feeding roller is placed somewhat closer to the beginning of the treatment line than the lower feeding roller.

Abstract: FLUSH TOILET ACCESSORY                   ABSTRACT OF THE DISCLOSURE             This invention provides a flush regulator for use in a toilet flush tank, in order to regulate the out-flow through the outlet pipe in such a way that less water is used per flush than normally is the case.  The regulator includes a gripping means for attaching to the vertical stem which is screwed into the standard ball valve, and the gripping means supports two upright post members from which upwardly open cups are supported.  The cup members are wholly to one side of their respective post members r and are positioned such that rotation of the regulator with respect to the bracket normally supporting the stem will bring one of the post members into contact with the bracket, rather than a cup member.  By insuring that the cup members do not contact the bracket, interference with the intended vertical motion of the regulator, ball valve and stem is avoided.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates generally to the shaping of a blank carried out by filter-dehydration as it is obtained from a sludge-like solid/liquid mixture and, in particular, to the shaping of a blank in a resilient mould-grid containing the mould negative utilizing sludge obtained from ore-dressing installations.  To date, there are no specific requirements regarding the shaping of blanks obtained in the above-noted manner since there appears hitherto to have been little or no knowledge regarding the significance of such requirements or of the relationship between shaping and function.  The present invention proposes to provide a blank of a configur-ation such that the somewhat conflicting requirements regard-ing functionally optimal shaping can be largely fulfilled.          Accordingly, the shaping of the blank is such that at least one projection of the blank onto a plane approximately at right angles to a surface of a filter has approximately a form of a trapezoid, the sides thereof which enclose an angle ?1 larger than 90° merging into each other with a curve.

Abstract: ABSTRACT OF THE DISCLOSURE     A rock drilling bit for a pneumatic percussion hammer has a bit head and an anvil extending up from the bit head and slidable in the bit drive sub of the hammer.  So the bit will be rotated with the hammer without unduely stressing the anvil, the upper part of the bit head is of non-round cross-section and slidable in a socket of corresponding cross-section in the bit drive sub.  If the anvil is not integral with the bit head, but is screwed into it, the lower part of the anvil is of matching non-round cross-section so torque applied by the rotating hammer is applied equally to anvil and bit head.

Abstract: ABSTRACT OF THE DISCLOSURE          A web tension monitor in which the tension of a moving web passing over a guide roll is monitored by a sensing device positioned upon a cantilever-mounted support which is coupled to a shaft which carries the roll.  Forces applied to the roll by the tensioned web passing over it are coupled to a fixed frame through the cantilever-mounted support by means of a pair of concentric rings between which bearing balls are disposed in confronting openings formed in both members at diametrically op-posed points.  Misalignment and expansion of machine components can be tolerated to a large degree without causing pre-loading of the sensing device.

Abstract: A PROCESS FOR THE MANUFACTURE OF OPTICAL FIBERS             WITH A RADIAL REFRACTIVE INDEX                Abstract of the disclosure A process yielding a glass blank in the form of a rod intended for drawing an optical fiber of the kind of self-focussing fiber i.e. having a radial refractive index gradient, having features (substantially transparency or transmission efficiency) lower than those of the fibers intended for long distance communication but sufficient for middle distance transmission, and which exhibits a lower cost than known processes. In a first stage a phase separation yields a "hard" phase (rich in silicon) and a "soft" phase (poor in silicon and rich in impurities) due to the drawing of a rod from a bath of molten glass through a cooling system having a strong temperature gradient and creating a radial refractive index gradient. In a second stage the soft phase is leached, eliminating the impurities contained in the soft phase but keeping safe the radial gradient. In a third stage a consoli-dation treatment is a pure annealing treatment rendering the hard phase more homogeneous.

Abstract: ABSTRACT OF THE DISCLOSURE A versatile by-pass humidifier assembly utilizes the flow of air therethrough as a driving force to rotate a fluid carrier subassembly.  The fluid carrier subassembly has a unique "drop-in" design enabling its easy removal and replacement, all without the use of tools or fasteners.  More particularly, an open-topped reservoir means is slidably received in the housing through an opening in the front section thereof, the reservoir means being accessible at the front of the housing for removal and replacement. The rotatable fluid carrier subassembly is rotatably received in a given position in the housing between the end walls thereof with a portion thereof adapted to contact fluid within the reservoir means via the open top thereof. The reservoir means and the fluid carrier subassembly are each removable from the housing separately from each other.  Means are provided for rotat-ing the fluid carrier subassembly through at least 360° and for operatively connecting the rotating means with the fluid carrier subassembly.  The gas to be humidified enters the housing through one of the apertures defined by the housing, passes through the fluid carrier subassembly to absorb moisture therefrom, and exits the housing through another aperture defined by the housing.
