Abstract: LOAD CHECK AND BYPASS VALVE     ABSTRACT         A load check and bypass valve includes a check valve providing fluid flow from an inlet-outlet port to a motor port while blocking reverse flow therethrough and a bypass valve resiliently biased to a closed position for blocking fluid flow through a bypass connecting the motor port with the inlet-outlet port.  The bypass valve has an opened position permitting fluid flow therethrough and is movable to its opened position by a selectively controllable actuating device.  A first force exerting device is provided for exerting a force on the bypass valve urging it towards its opened position and is connected to the motor port by a first passage.  A second force exerting device is provided for exerting a force on the bypass valve urging it towards its closed position and is connected to the motor port through a second passage.  A check valve is disposed in the second passage providing fluid flow therethrough from the motor port to the second force exerting device while blocking reverse fluid flow therethrough.  An orifice communicates with the second passage between the check valve and the second force exerting device.

Abstract: NON-CLOGGING SCREEN APPARATUS            ABSTRACT OF THE DISCLOSURE     A vibratory screening apparatus has a pair of screen cloths in close face to face abutment with the strands or wires of the lower screen cloth generally intersecting the openings of the upper screen cloth to prevent "blinding" of the upper screen cloth by reason of the tendency of the strands of the lower screen cloth to prevent engagement of particles in the upper screen cloth of a size which would tend to clog the openings of the upper screen cloth.  The mesh size of the lower screen cloth may be equal to the mesh size of the upper screen cloth or slightly larger than the upper screen cloth openings up to about fifty per cent larger.  The superposed screen cloths may rest upon a much coarser mesh screen which serves merely as a structural support for the screen cloths and does not perform a screening function, the coarser mesh screen having upper edges defining a transverse arch for supporting the screen cloths in an upwardly arched formation so that the longitudinal strands of one screen are held securely against the transverse strands of the other screen and vice versa.

Abstract: ABSTRACT OF THE DISCLOSURE A dye binding reagent fox protein assay comprises Coomassie Brilliant Blue G-250 and an acid having a pKa of from 1 to 2.  Upon addition of the reagent to a protein-containing solution, the attendant color change can be spectrophotometrically measured to quantitate even micro-grams of protein.  Furthermore, the reagent is applicable to a wide range of proteins and requires only about 2 minutes of measurement.  Addition of an alcohol such as ethanol to the reagent further improves sensitivity.

Abstract: ABSTRACT           Reinforced corrugated fiberboard containers are disclosed which can be produced in a high-speed continuous process from a sheet of single-face corrugated material comprising a corrugated web adhesively secured to a single facing sheet having a width much greater than that of the web to provide outwardly extending fly portions of substan-tial width.  The web forms the corrugated core of a single-wall laminated board formed by turning over the fly portions to reinforce the side edges and securing the fly portions to the corrugations to partially cover the core and to pro-vide the board with double-faced side portions and an unrein-forced single-faced middle portion.  The laminated board can be passed through rotary cutting dies or the like in a high-speed continuous process to cut and form slotted box blanks.

Abstract: ABSTRACT          The present invention relates to an electrical connector assembly and, more particularly, to a sealed connector assembly configured to reduce the force required to effect the electrical connection.  Prior art receptacle members and plug members are individually formed of resil-ient insulating material having a high coefficient of friction.  This makes it possible for the primary mating seal to be accomplished by the meting halves with an inter-ference fit.  This compounds the meting problem, however, due to the considerable force required to provide straight push-pull mating without skewing or bending the mating halves.  The interference fit also masks the "feel"  of align-ment of the contacts, increasing the possibility that the contacts will be bent or damaged.  The receptacle member of the present invention has a recess at one end defined by a resilient wall having an outer end terminating in an inward-ly projecting lip.  The plug member has a projection at one end defined by a neck portion having an inner end termina-ting in a contact-receiving face.  The plug  ?mber also has a collar axially located on the neck portion to cooperate with the lip in providing an environmental seal with the neck having a maximum transverse dimension no larger than the inner diameter of the lip but with the collar being larger in transverse dimension than the lip.  The collar is positioned along the neck portion such that the first contact mates with the second contact prior to engagement of the lip with the collar.
