Abstract: Abstract Three adjacent continuously running chain link assemblies having two contiguous common paths, respectively in those paths (1) form staples from lengths of wire and (2) insert and clench the staples while creasing a signa-ture passing through the linear path defined by the contiguous chain links.  This produces simplified equip-ment operable at high speeds synchronously on line with signatures from a rotary printing press, or the like.  The wire lengths are handled and formed into staples by very simple non-critical mechanical means constituting a magnetic male die member and female shaping die member carried by respective contiguously traveling chain link assemblies to mate as they move about sprockets into an arcuate path leading into their contiguous mated linear travel path.  Similarly the staples are passed through the signatures and clenched in entering the second contiguous path where incremental chain link carried creasing die sets grasp, transport and crease the signatures over the linear contiguous pathway to present a folded and stapled output signature.

Granted: 1984-11-06
Abstract: Continuous Flow Urological Endoscopic Apparatus Abstract A continuous flow urological endoscopic appar-atus includes an endoscope having a reciprocatively-mounted treating device.  For circulating fluid into and out of a body cavity for flushing purposes, a delivery conduit conveys clear irrigating fluid under pressure to the interior of the body cavity via the open end of the endoscope sheath.  A return conduit withdraws turbid fluid from the interior of the body cavity.  An inlet of the return conduit is positioned within the sheath forwardly by a sub-stantial axial distance from the objective lens of a telescope, and spaced radially from the axis of the lens.  The return inlet directs turbid fluid forwardly away from the objective lens for clearing turbid fluid continuously out of the field of view of the objective lens, thereby enhancing greatly the visi-bility of the operative field for much longer periods of time.  The return inlet is positioned near the outer-most protracted position of the treating device so that the flow of fluid is away from the objective lens and also provides for good negative pressure for the return flow of fluid at all positions of the treat-ing device.  A pressure sensing device is mounted within the sheath for detecting fluid pressure within the body cavity, and an electric conductor conveys signals indicative of the internal pressure within the body cavity, for safety purposes.  Pump devices establish the continuous flow of fluid into and out of the interior of the body cavity via the delivery and return conduits, respectively.  A control circuit responds to the signals for de-activating the pump device when the fluid pressure within the body cavity exceeds a predetermined unsafe value of pressure.

Abstract: CONVEYOR ASSEMBLIES FOR DETACHABLE MOUNTING TO A TRACTOR            ABSTRACT OF THE DISCLOSURE          Present conveyors such as portable grain augers are most commonly positioned, raised and lowered manually and are powered by a small air-cooled engine, electric motor or a tractor power take-off.  The disclosed conveyor system utilizes a tractor for all modes of transport, positioning, raising and lowering, and powering the conveyor.  The under-carriage configuration allows a tractor to be coupled beside and in parallel with the conveyor.  The undercarriage moves as a unit with the tractor but is freestanding when uncoupled.          The tractor power take-off is utilized to drive the conveyor through the use of any one of several drive systems and the tractor electrical and hydraulic systems may be used to power controls for raising and lowering the conveyor.  In grain au-gers, in addition to the mechanical auger flighting used to move the grain, a pneumatic system may also be adapted to this unit.  Its function is primarily the same as that of present drag or clean-up augers which are used to move grain toward the auger intake during clean-up operations.  The pneumatic system features only a suction stage with the grain being taken in through a suction hose and deposited into a cyclone above the auger flighting.  The blower or fan is mounted on the undercarriage behind the tractor and is powered by the tractor power take-off independently of the auger flighting.

Abstract: SILICON LAMINATED MEDIA FOR  ARCHIVAL OPTICAL STORAGE                  ABSTRACT            Laminated media for optical storage of data in binary form include bi-layer and multi-layer structures of silicon and another element preferably a transition metal.  Metals more useful are included in Groups VB, VIB, VIIB, and VIII on the periodic chart plus Mg and Au.  More advantageous elements within the above group include V, Nb, Ta, Cr, Mo, W, Mn, Fe, Co, Rh, Ni, Pd, Pt, and Au.  The most effective elements are Pd, Pt, Cr, Ta, Rh, V, and Co.  The metal can be deposited upon a silicon layer or vice versa.  The latter is preferred where a recording laser beam hits the silicon layer first because the amount of energy reflected is reduced and the silicon layer on top passivates the metal layer.  The materials are non-toxic.  Bi-layers of rhodium and silicon have extremely long lifetimes, Pt and Si are long, Pd and Si are less long and Te alone has an extremely short lifetime comparatively.

Abstract: Abstract Sync-positive and sync-negative video signals appearing across load resistors (46,45) of synchronous video detector employing array of NPN transistors are coupled via respective voltage dividers (52,54;53,55) to complementary inputs of differential amplifier employing NPN transistors (57,59).  Signals appearing across load resistor (58) of amplifier are coupled via an active filter (70,71,72,73) to video signal output terminal (10). Detector load circuits (45,46), amplifier load circuit (58), and active filter (70-73) each provide high frequency roll off with break point lying between desired video passband and second subharmonic of picture carrier intermediate frequency.  Active filter provides response boost within high end of video passband, and response null in vicinity of picture carrier intermediate frequency.  Level shift circuit (70,71,74) utilizes series resistance of active filter.  Differential amplifier (57,59) has current source (60,61) responsive to amplifier output to avoid cut off of amplifier transistor receiving sync-negative drive.

Abstract: APPARATUS FOR MEASURING BLOOD PRESSURE                 ABSTRACT OF THE DISCLOSURE           The open end of a catheter is inserted in the blood vessel of a patient.  The catheter is connected by hollow tubing to a physiologic pressure transducer.  The tube is filled with an intermediate pressure-transmitting fluid such as a physiologic saline solution.  An infusion device between the patient and the transducer constantly flushes the system with a slow flow of fluid.  Blood pressure variations are transmitted through the fluid to the transducer, which converts the pressure to electronic information and transmits the information to a monitor for display.  Between the infusion device and the transducer is a variable restrictor which damps the pressure waves in the fluid.  This restrictor is used to tune the system to eliminate resonant waves, which distort the monitoring reading.  In one form, the variable restrictor includes a valve having an orifice, the effective size of which is reduced or enlarged by compressing and releasing a deformable, flexible ring.  In another form, the variable restrictor includes a valve which has a valve seat with a flow opening through which the fluid pressure wave passes.          To control pressure wave flow through the valve, a valve needle is moved toward and away from a valve seat, which reduces and increases the size of the flow opening.

Abstract: ABSTRACT OF THE DISCLOSURE           A water driven power system has a cylindrical body with valved water supply and drain ports in the bottom thereof, the valves including valve plates rotatable between valve open and valve closed positions.  A float is freely movable up and down between an upper limit position and a lower limit position in the cylindrical body due to buoyancy during supply of water through the supply valve and due to gravity during drainage through the drain valve.  The float movement during the time of water supply is converted to rotation and a one-way clutch mechanism supplies the motion to an output mechanism.  A valve opening and closing mechanism closes the water supply valve and opens the drain valve at the upper limit position of the float and opens the water supply valve and closes the drain valve at the lower limit position of the float.  A linkage is connected to the respective ones of the valve plates end is driven up and down for moving the valve plates in rotation by springs which are compressed and then caused to drive the linkage when the linkage is released.
