Abstract: ABSTRACT The electron applicator incorporates a stationary support tube and an insert tube.  Thee support tube and the insert tube each have a first end portion and a second end portion.  The first end portion of the insert tube slideably ex-tends into the second end portion of the support tube.  Electrons of high energy are transmitted through the assembly of both tubes.  The surface of the insert tube is tapered inwardly toward the end thereof in the travelling direction of the high energy electrons.  A device is provided for preventing the insert tube from sliding out of the support tube.  A first engaging device engages the in-sert tube in a first working position.  This device is such that upon a predeter-muned axial force which may inadvertently be exercised by a patient under treat-ment, the insert tube will slide into the support tube.  An adapter for small field or cavetory treatment may be connected to the output end of the insert tube. To compensate for the additional length of the tube assembly associated with such an adapter, the insert tube is moved into the support tube by a distance equal to the effective length increase and held in this second position by a second engag-ing device which can be similar to the first engaging device.

Abstract: VENEER LATHE CHARGER HAVING IMPROVED POSITIONING FOR CHARGER SPINDLES     Abstract A veneer lathe charger apparatus is described having an improved charger spindle positioning system which is less vulnerable to damage, is of simpler construction and is of faster operation.  The charger spindle positioning system includes spindle support and adjustment means for moving the spindles both horizontally and vertically by linear movement in one direction of linear positioning means at the opposite ends of the log.  The linear positioning means are located above the log so as not to be damaged by a falling log.  Each linear positioning means includes a pair of cylinders whose piston rods are pivotally attached to a spindle support plate on opposite sides of the spindle.          A log support and centering means receives logs at a pick up position and transports such logs to a scan position after rough centering the logs with their longitudinal axis in such a scan position.  The charger spindles engage the log in the scan position and rotate the log while it is scanned with a light beam to determine the optimum yield axis of the log for the greatest production of wood veneer.          The charger spindles are then moved automatically by the linear positioners to move the log from the scan position until its optimum axis is aligned with a transfer position located at a predetermined position relative to the lathe axis.  Transfer arms engage the log to move the log from the transfer position to the lathe where the optimum axis of the log is in alignment with the lathe spindle axis.  The log support and centering means returns from the scan position to the pick up position and does not reclamp the log in the transfer position.  As a result the log is only held by the charger spindleswhen it is engaged by the transfer arms in the transfer position.  No reclamping of the log is necessary because in the scanning position the charger spindles are spaced sufficiently below the transfer position to provide clearance for the transfer means as it moves back from the lathe axis position to the transfer position.  This enables four logs to be simultaneously acted upon by the lathe charger apparatus of the present invention and greatly increases the speed of operation of such charger.

Abstract: ABSTRACT OF THE DISCLOSURE        A machine for "dry mix" packerhead concrete pipe manu-facture has two stations and a separable tubular jacket movable therebetween.  A rotatable cylindrical packerhead is movable axially within the jacket and a "dry mix" delivery means deposits mix atop the packerhead as it rotates and moves vertically up-wardly within the jacket.  The packerhead distributes the mix thereabout to form a concrete pipe in the jacket.  A radially ex-pandable and contractable core is movable axially in a contracted condition to a position within the pipe and is then expanded.          Vibrators within the core are operated to "redensify" the pipe; that is, to compact the mass thereof, to eliminate voids, and to relieve residual forming stresses therein.  A guide ring is employed to align the contracted core axially with the pipe during entry and further guiding and supporting devices for the core are provided.  Core entry and withdrawal is power actuated as is core expansion and contraction within the pipe.  Expansion and contraction devices may comprise fluid cylinders operated adjacent a single axial split line in the core or, true circle expansion and contraction means may be provided with a core having one or more axial split lines.

Abstract: DUMP DELAY VALVE            Abstract:       A delay valve (10) has a body defining an enclosure (14), with a separating plate (16) and diaphragm operator (22) therein to define an input (18), output (20) and third (24) chamber.  The input (18) and output (20) chambers are adjacent, and separated by the separating plate (16).  This plate (16) defines an aperture (30), an umbrella valve opening (26) and a port (28), all of which communi-cate between the input  (18) and output (20) cham-bers.   A stem (40) and seal (42) arrangement is affixed to and operable by the diaphragm operator (22) against the bias force of a spring (44), to seal communication through the port (28) at and above a pressure differential between the output (20) and third (24) chambers.  As the input (18) chamber vacuum decreases,  the output (20)  chamber vacuum level likewise decays through the aperture (30) at a relatively slow rate.  When the pressure differential between the output (20) and third (24) chambers is inadequate to overcome the bias force of the  spring  (44), the port  (28)  opens and thus produces equilibrium between the input (18) and output (20)  chambers.   This delay valve (10) thus rapidly returns to an equilibrium position and is again ready to commence controlling without awaiting a slow decay return to equilibrium.
