Abstract: ABSTRACT OF THE DISCLOSURE     A sensing apparatus is described for use in a target indicat-ing system operative selectively to signal a strike on a target plate.  The target indicating system includes an actuator mechanism adapted to be driven by a pressurized gas, conduit and servo control means in flow communication with the actuator mechanism and adapted, in use, to supply gas under pressure to the actuator mechanism.  A strike sensing apparatus or assembly is also included, connectible, in use, to the conduit and servo control means.  This sensing apparatus includes a housing defining a cylinder therein having one portion thereof adapted to be in flow communication with the source of pressurized gas.  A piston is provided being slidably movable in the cylinder. The piston has a bleed channel therein to depressurize the cylinder.  A motion-sensitive weight, preferably in the form of a sphere, is supported by the piston and acts on a needle valve to keep the bleed channel closed.  This weight is moveable in response to a strike on the target plate, enabling the bleed channel to be uncovered, thereby causing rapid depressurization of the cylinder and a correspondingly rapid lowering of the target.  Preferably the weight is a spherical  ball and the stem portion of the piston is formed with a spherical seat for supporting said ball.  In another preferred form of this apparatus, biasing means are included, supported in the cylinder housing to cause retraction of the piston when the cylinder has been depressurized.

Abstract: ABSTRACT OF THE DISCLOSURE           A dynamic concentrator for separating a filtrate and a concentrated slurry from a solids-containing fluid.          The concentrator comprising a housing having an inlet for introducing a solids-containing fluid therein and an outlet for removing a concentrated slurry of solids therefrom.          Two coaxially spaced apart annular elements are mounted within the housing between the inlet and the outlet.  A shaft extends coaxially through the housing with a radially extensive element secured coaxially thereto and located between opposite facing surfaces of the annular elements thereby to provide a flow path for solids-containing fluid from the inlet to the outlet which extends across the surfaces and from one side of the radially extensive element to the opposite side thereof passing around the outer periphery of the radially extensive element between the outer periphery and the interior surface of the housing, and from one side of each of the annular elements to the opposite side thereof passing around the inner peripheries of each of the annular elements between the inner peripheries and the shaft.  The concentrator is arranged to have a motor coupled thereto for causing relative rotation between the shaft and the radially extensive element and the annular elements.  At least one of the elements comprises at least one filtering surface with the interior side of the filtering surface being in fluid communication with the exterior of the housing for the removal of filtrate from the housing.          The concentrator is characterized in that at least one plough member extends inwardly from the inner periphery of each of the annular elements into the flow path to deter accumulation of solids in the region defined radially between the surface of the shaft and the inner periphery of each of the annular elements during the relative rotation.

Abstract: ABSTRACT OF THE DISCLOSURE           In an optical line tracer of the circular scan-ning type, it is advantageous to have different scanning diameters depending on the velocity of tracing and other factors.  The present invention provides for continually adjustable scanning diameter by adjusting the angle of a reflecting mirror type scanner.  In normal operation, the mirror of the scanner is rotated about an axis which is at a small angle relative to a perpendicular to the mirror. This causes light impinging on the mirror to describe a circular path as the mirror is rotated on the axis.  By providing a continual adjustment of the angle of the mirror, the diameter of the circle described by the reflected light can be adjusted.
