Abstract: Docket 6173 METHOD AND APPARATUS FOR RECOVERING PAPER FIBERS FROM WASTE PAPER CONTAINING MATERIALS          Abstract of the Disclosure Waste paper containing materials, e.g. commercial "waste paper", are treated for recovery of reusable paper therefrom by slushing in a pulper from which two fractions are continuously extracted - a first fraction through small holes, e.g. 1/4 inch, and a second fraction through substan-tially larger holes, e.g. 1 inch.  The second fraction is screened, preferably after a centrifugal cleaning operation, in a screen having small perforations sized to accept only substantially defibered paper, and the accepts flow is mixed directly with the first extracted fraction.  The reject flow from this screen is conducted, with or without an intermediate deflaking operation, to a tailing screen from which the accepts are recycled to the pulper and the rejects are eliminated from the system.  Major advantages of this method and system include the continuous elimination of plastic and other floating trash from the pulper, a high degree of essentially complete defiber-ing in the pulper, and minimal recycling of adequately defibered stock.

Abstract: Abstract of the Disclosure The invention provides an advancing member for use in a system for the so-called "cube" storage and retrieval of a large number of items, such as loaded pallets.  Such a system employs a frame providing a plurality of parallel storage paths arranged in one-upon-the-other rows and side-by-side tiers. Each path provides a plurality of stations each able to store an item, and is provided with a respective advancing member which is motor-operated and extends substantially the full length of the path, the motor reciprocating the member back-and-forth. The advancing member carries for each station a pendulous lockable driving advancing means engagable with the item therein to move it to the next successive station as the member moves; it also carries a similar detector means, which may be constituted by the respective driving means, to detect the presence of an item at a station and unlock the preceding driving means so as to prevent the feeding of an item to an already occupied station.  The entry and delivery ends of each path are provided with respective detectors to control movement of the advancing member to ensure that the delivering station is always occupied.  The direction of feed of the advancing member is reversible.

Title: Golf ball retriever
Inventor: WALTER ERHARD P
IPC: A63B47/02

Granted: 1980-03-04
Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an improved golf ball retriever of the type which may be lowered directly over the ball.          The retriever has a telescopic handle for reaching into water hazards and the like.  The handle is pivotally connected to a body member which has a pair of lower forwardly extending curved arms and a retaining ring pivotally connected at its rear to the body member at a point above the plane of the curved arms.  Thus the retaining ring normally slopes forwardly downward and rests on the ends of the curved arms.  The ring is slightly larger in diameter than a golf ball and when the retriever is lowered over a golf ball, the ring pivots slightly upward to increase the effective size of the opening between it and the curved arms to allow the ball to pass therethrough.  When it has, the ring drops down past the outside of the ball, and the retriever is then lifted upwards with the ball engaged by the ring and the curved arms.  The body member has an upper curved holding finger which prevents the ball from being dislodged and to which the handle is pivotally connected.  This structure provides the advantage that the ball may be released simply by resting the body member on the ground and pulling forward on the handle.          This automatically pivots the body portion about the ball and the retaining ring to release the ball.  In other embodiments, the retaining ring may be rectangular or triangular with the body portion having arms to match.

Abstract: ABSTRACT OF THE DISCLOSURE    An induction heating apparatus includes a pair of thyristors inversely parallel connected to receive power from a low frequency energy source, a commutating circuit and a gating control circuit for supplying control pulses to the thyristors to produce a forward halfwave current through the commutating circuit which in return produces a backward commutating current to the thyristors.          The gating control circuit includes a pulse transformer having a pair of secondary windings connected to the thyristors and a primary winding responsive to control pulses supplied from a pulse generator to produce a positive gating pulse in each of the secondary windings to drive one of the thyristors into conduction depending on the polarity of the source voltage to produce the forward current.  The control pulse has a longer duration than the maximum duration of the forward halfwave current so that upon cessation of the forward current the other thyristor is gated into conduction to allow the backward commutating current to pass therethrough to complete an oscillation cycle.  A counterelectromotive force is generated in the secondary windings in response to the trailing edge of the positive gating pulse to negatively bias the thyristor to quickly turn it off.
