Abstract: CRANE BOOM TOP PLATE LATERAL SUPPORT                    Abstract To resist side deflection and buckling of the top (26-26d) and side plates in larger size multi-section telescopic crane booms, top plate lateral supports (37) for the movable boom sections (21,22, 23,24) in the fully extended and fully retracted critical zones are provided to supplement the action of bottom lateral wear pads (36).  The top plate lateral supports (37) include adjustable spring bars (41) on the sides and forward ends of the boom sec-tions and coacting cam pads (47,48) on the top plates (26a,26b,26c,26d) of the boom sections, at their for-ward ends for when the boom sections are fully re-tracted, and in the socketing zones for when the boom sections are fully extended.

Abstract: ABSTRACT OF THE DISCLOSURE      A sleeve valve is carried in a parenteral solution ad-ministration device.  The valve comprises an outer-housing (30) defining an outlet tube (28); an inner tubular support (38) defining an inlet tube (45) and a closed forward end positioned within the outlet tube.  Lateral aperture means (46) are provided in the tubular support, and an elastic tube (40) surrounds the inner tubular support to cover the lateral apertures. The inner tubular support is free of elastic, tube-retaining structures at its closed end, and is adapted to permit the elastic tube to be laterally slid-able on the inner, tubular support through a limited dis-tance.  The outer housing defines vanes (44) to limit the lateral advancement of the elastic tube on the support, while shoulder means (42) are positioned about the support to limit the lateral retraction of the elastic tube away from the closed end.  Accordingly, pressurized fluid flow through the inlet tube causes expansion of the elastic tube by pres-sure to permit fluid flow between the tube and tubular sup-port out of both ends of the elastic tube.  The valve can have higher flow rates at lower pressures, while at the same time having a lower residual volume.

Abstract: ABSTRACT OF THE DISCLOSURE   The invention is intended to eliminate the far-end cross-talk effects between transmission lines grouped together in one link by employing filtering means already introduced into the receiving channel of a terminal or intermediate station of a half-duplex transmission line. The far-end crosstalk minimizing device is included in a half-duplex digital trans-mission station linked to a line section whose other end is a grouping point for the lines and which produces an attenuation less than a maximum attenuation. It comprises an equalizing circuit and switches. The equalizing circuit is included in the receiving channel of the station and includes a filter having a transfer gain practically equal to the difference between the attenuation of the line section and the maximum attenuation. The switches introduce the filter in series into the transmitting channel of the station during each transmission operation of the half-duplex station cycle.

Abstract: ABSTRACT Apparatus and a process are disclosed for removing a single flexible member from a magazine capable of holding multiple flexible members.  The magazine is designed to contain multiple elongated flexible members such that the bottommost flexible member is retained in the magazine by means of detents positioned on both sides of an opening located at one end of the magazine; each detent comprises a ledge extending at an angle greater than 90° and less than 180° from an end wall of said magazine.          The apparatus also comprises a pick-up head or vacuum transport member which is capable of passing through the opening of the magazine and contacting a portion of the bottommost flexible member inside the magazine. By supplying a vacuum through the pick-up head or vacuum transport member the bottommost flexible member can be made to flex or bend sufficiently as the pick-up head is removed from   the opening in the lower end of the magazine to effect the withdrawal of one flexible member (the bottommost flexible member) at a time from said magazine.  The invention has particular applicability to the handling of test devices used in the determination of a particular constituent in a liquid sample.

Abstract: ABSTRACT      A toilet  seat hinge mounting assembly for top attachment to a commode having a vertical mounting hole includes a base member mountable on the top surface of a commode with an elongated hollow stem extending downwardly from the base member and having an axial opening extending axially along its length and having an outer configuration permitting it to be inserted matingly downwardly into a commode mounting hole; the stem is divided into first and second stem halves separated by a diametric slot extending upwardly from the lower end of the stem with the lower end of the stem halves being defined by planar follower surfaces that are oriented at an acute angle relative to the axis of the stem with the lower ends of the planar follower surfaces flaring outwardly from the axis of the stem.  A threaded bolt extends downwardly through the axial opening in the stem with a camming a nut being mounted on the bolt below the lower end of the stem; the upper end of the nut is defined by two upwardly converging planar  camming  surfaces  each  oriented  substantially parallel to and facing one of the planar surfaces defining the lower extent of the stem.  Rotation of the bolt is effected by use of a screwdriver from above the commode and the planar camming surfaces on the nut engage the planar surfaces defining the lower extent of the stem to prevent rotation of the nut which is consequently moved upwardly with the planar camming surfaces consequently also serving to force the stem halves apart into forceful contact with the mounting hole to effect retention of the stem therein.
