Abstract: Abstract of the Disclosure Microporous anionic exchange and non-ionic adsorbent resins which are capable of adsorbing an antibiotic and which have been coated with a non-ionic detergent are disclosed. When contacted with bacterially infected body-fluid specimens, the disclosed rosins remove antibiotics from the specimen while exhibiting diminished bacterial adsorption. A combination of a disclosed detergent-coated non-functional adsorbent resin with a cationic resin removes other bacterial inhibitors, as well as antibiotics, from bacterially infected body fluid specimens while permitting the bacteria to remain in the specimens. By removing bacterial inhibitors while sparing the bacteria, the disclosed resins make possible rapid isolation and identification of an infecting organism.

Abstract: ABSTRACT OF THE DISCLOSURE          This invention discloses a novel fluid motor or pump comprising a housing having a bore, a rotor body mounted for rotation in the bore and defining therewith an annular space, and a plurality of circumferentially spaced longitudinally extending blades mounted  in slots on the outer periphery of the rotor body.  Each of the blades is made of a resilient flexible material and has one of its longitudinal edges secured to the rotor body to form a blade corner about which the blade is flexed. The free portion of the blade pivots due to its resilience to swing its other longitudinal edge into frictional sealing engagement with the wall of the  bore.  Longitudinally extending separator strips are mounted on the housing in the bore and divide the annular space into at least two chambers.          Inlet ports opening through the housing to each chamber are provided adjacent the trailing edge of each separator strip considered in the direction of rotor rotation, and outlet ports opening through the housing to each chamber are spaced a short distance from the leading edge of each separator strip on the leading side thereof so as to provide a closed cavity between the trailing edge of the port and the separator strip when the leading side of a blade passes the discharge port, thereby trapping fluid in the cavity to act as a buffer.  With this construction, the life of the blades and motor can be signi-ficantly improved and the wear and vibration on the motor is is reduced.

Abstract: Abstract Tree cutting equipment that may constitute a part of the head of a tree harvester includes a saw assembly and a shear assembly, the shear and saw being movable towards each other, preferably in substantially the same plane.  A stop associated with the shear assembly and engageable with the saw assembly limits the extent to which the saw can approach the shear so as to prevent the saw from attempting to cut completely through the trunk of a tree located between the shear and saw.  The stop is located on the side of the pivot point for the saw that is remote from the shear, and a window is provided in the arm that supports the shear to permit the ejection of saw chips.

Abstract: FLUID BLAST CIRCUIT INTERRUPTER INCLUDING OBSTRUCTION-FREE FLUID RELEASE FACILITY ABSTRACT: An improved circuit interrupting device includes a pair of relatively movable contacts between which an arc is established. As the contacts are moved apart to elongate the arc, a container of pressurized dielectric fluid directs a flow of the fluid from a port at the arc. A diaphragm which normally closes the port to prevent fluid flow is mechanically attached to one of the contacts. When the contacts are moved apart, the container and the one contact also move apart tearing or cutting open the diaphragm to permit the fluid to flow at the arc. The tearing or cutting of the diaphragm is performed in the direction taken by the fluid when it flows. Thus, there is nothing at the former location of the diaphragm to obstruct its flow. Both relative contact movement and the relative movement of the container and the one contact are effected by the action of the ignition products of a power cartridge on a piston-cylinder.

Abstract: D-21,521 CONSTANT PERCENT BREAK                TYPE DIAL PULSE CORRECTOR by Nam Tosuntikool and Robert Yapp ABSTRACT OF THE DISCLOSURE     The first astable multivibrator of a series connected pair of astable multivibrators is responsive to each break interval of input dial pulses for establishing a fixed time delay after which the second multivibrator initiates a corrected break interval and starts a first timing capacitor thereof charging at a rate set by a fixed time constant.  Each input break interval also causes a capacitor of a second timing circuit to start discharging at a rate set by another fixed time constant, the time that the second capacitor starts discharging being a function of the pulse repe-tition frequency of input dial pulses.  When the charge voltages on the two capacitors are the same values, the output of a comparator resets the second multivibrator to terminate an output break interval so as to cause corrected dial pulses in the output thereof to have a constant percent break.

Abstract: Equalizing System for Load Lifting Apparatus Abstract Lift trucks having two laterally spaced apart motors for lifting a load on a carriage provide excellent forward visability for operators thereof. When the load is unevenly disposed upon the carriage, or the lift truck encounters uneven terrain, the lifting components of the lift truck are subjected to unequal stresses.  Such unequal stresses, if uncorrected, reduce the useful life of the lifting components, particularly a pair of chain assemblies associated with the carriage.  A load equalizing system has first and second guide assemblies each having a slot and a pin which connects each motor to a movable structure and maintains substantially equal tension in the pair of chain assemblies when off-center loading is encountered.  The load equalizing system permits one motor to move a predetermined distance relative the other in response to off-center loading, which equalizes tension of the chain assemblies and which thus extends the useful operational life of the lifting components.
