Abstract: ABSTRACT OF THE DISCLOSURE:           An apparatus for testing the crosspoints of a multiple stage end-marked switching network.  The network being tested comprises in each stage at least one orthogonal matrix of bi-stable, solid-state crosspoints.  The network has a predetermined plurality of unique paths between each fixed point at the oppo-site ends of the network.  Those pachs are clearly defined in at least one intermediate stage of the network such that the paths can be checked for open circuit conditions and short circuit con-ditions by enabling specific paths or groups of paths in that stage and inhibiting all other paths or groups of paths.  The apparatus shown may be controlled by controls which may be incor-porated into a stored program controller controlling the switch-ing network or by means of a computer programmed to perform rou-tining of the exchange including the network.

Abstract: ABSTRACT OF THE DISCLOSURE     A pressure reducing valve according to this invention consists of a housing for a valve seating member and the valve member.  The housing has a main chamber located therein within which the valve seating member is mounted for longitudinal movement.  A valve chamber is formed in the valve seating member and is proportioned such that the valve seating member is balanced with respect to the pressure of fluid in the inlet side of the valve.  The valve member is mounted in the valve chamber and secured with respect to the housing against movement such that the valve is closed by movement of the valve seating member into engagement with the valve member when the pressure downstream of the valve member exceeds the predetermined maximum output pressure.   The valve provides throughput  passages which are axially alligned with one another to minimize the turbulence in the flow of fluid therethrough.

Abstract: ABSTRACT          In printing on continuous webs, it is known to employ a sequence of ink-image combinations to achieve the full image result. In the case of contiguous patterns printed on a continuous web, such patterns are often printed from the same printing plates repeatedly and frequently comprise products which are of standard widths. The invention concerns the use of laterally separated flexographic printing members in combination with multiple ink fountains for the purpose of improving productivity and efficiency of manufacture.

Abstract: Abstract of the Disclosure In a centrifuge including a centrifuge rotor and a drive shaft for spinning the rotor at selected rotational speeds, a safety device adapted to prevent the rotor from attaining a ro-tational speed likely to cause the rotor to explode with a force that could not be contained within the centrifuge housing.  The device includes a hub member having a central opening adapted to receive the upper end of the drive shaft for supporting the rotor thereon, the hub member being formed with oppositely disposed heavier portions connected by relatively thinner web sections.          The web sections are so designed and constructed, relative to the weight of the heavier sections, as to rupture at a predeter-mined rotational velocity of the rotor thereby causing the hub member to depart from the shaft, leaving no driving capacity or support for the rotor on the shaft, which then causes the rotor to separate from the drive shaft before attaining a hazardous rotational speed.

Abstract: HEART VALVE PROSTHESIS                Abstract of Disclosure A heart valve having a base with a passage and a free-floating pivoting disc for controlling the flow of blood through the passage.  Inwardly directed proximal and distal pivots control the pivoting movement of the disc.  The pivots are offset from the diameter of the disc so that the disc pivots between its open and closed positions between its center and an outer peripheral edge of the disc.  The disc is held in free-floating as-sembled relation with the pivots and base with a curved retaining rod having a curved end projected through a central hole in the disc.  In one form of the valve a per-manent magnet in the disc assists the closing of the disc in response to a drop in the pressure of blood moving through the valve passage.  A suture collar surrounds and is mounted on the outer portions of the base.  A low fric-tion sleeve interposed between the base and the collar permits rotation of the valve relative to the suturing collar after the collar has been attached to the heart tissue.

Abstract: ABSTRACT OF THE DISCLOSURE     The back filter automatic vehicle wash water reclaim system of the present invention includes wash and rinse bays with wash and rinse sumps being provided for collecting used water therefrom.  Two pairs of back wash filter tanks are pro-vided for receiving used water from the rinse sumps and such tanks are characterized by the fact that water can be flowed in the reverse direction therethrough to clean such filter tanks for future filtering of rinse water.  The filter tanks are con-nected with the rinse sump by means of rinse conduits which connect the inlets of such filter tanks in parallel.  The out-lets of such filter tanks are connected with one another and a back wash conduit is provided which leads from the respective inlets of the filter tanks to a separator pump which directs back wash water through a separator for return to the wash water sump for subsequent use in spraying through a rinse arch and onto the surface of a vehicle to be washed. Valves are pro-vided for selectively controlling the water flow from the rinse pump during the vehicle rinse mode to direct such water in a forward direction through such pairs of filter tanks and to the rinse arch.  During the back wash mode, such control system actuates the rinse pump and valves in the rinse and back wash conduits to selectively direct the water first in a forward direction through one pair of filter tanks to be returned through the back wash conduit to such separator pump to be directed to the separator itself and back to the wash water sump for subsequent use in vehicle wash. The control system is also operative to subsequently direct the water from the rinse sump in a forward direction through the other pair of filter tanks and then in a reverse direction through such one pair of filter tanks to thereby back wash such one pair of filter tanks and direct the back wash water also through the separator to the wash sump.

The control system includes means whereby the transmission is placed in neutral, automatically, whenever the brake is to be disengaged to lower a load and a control valve including a spool with small and large slots along with a drum-driven metering pump controls fast and slow lowering speeds.  Emergency free fall of the load is accomplished in the valve by bypassing the small metering slot.  An arrangement of an accumulator and check valves allow hydraulic disengagement of the brake even if the engine is dead and there is provided a recirculating hy-draulic circuit to conserve oil in such an instance so that the accumu-lator volume can be minimized.  A system is included whereby the accumulator may be discharged, when the prime mover is inoperative to allow the operator of the winch to leave the location with the load suspended with the knowledge that the load cannot be lowered either intentionally or accidentally.
