Abstract: Abstract of the Disclosure The invention relates to an apparatus for the continuous electrochemical purification of contaminated liquids.  The apparatus includes an electrocoagulation chamber containing an electrolyte and having upstanding soluble elongated electrodes therein.  Electrolyte is introduced into the electrocoagulation chamber and flows the electrolyte between the electrodes.  Contaminated liquid is introduced into the electrocoagulation chamber while it contains the electrolyte.  The electrodes are disposed laterally spaced from each other and extending in parallel relationship, and a plurality of solid elongated insulative partitions are disposed next adjacent to the electrodes or between adjacent electrodes to define jointly with the electrodes a plurality of separate liquid flow paths between the next adjacent electrodes to preclude mixing and turbulence of the electrolyte as it flows through the flow path.

Abstract: ABSTRACT OF THE DISCLOSURE          A universal joint for connecting a pair of elongated members is disclosed.  The joint provides for transmission of torque between the pair of members when the pair of mem-bers are oriented at various angles relative to each other. One of the members terminates in a cavity, or housing, which is substantially cylindrical.  The other member extends into the cavity and a pair of sockets cooperate with the other member to secure the latter within the cavity.  The pair of sockets include outer surfaces which substantially match with the cylindrical cavity surface to enable the pair of sockets to rotate in a plane relative to the one member. The pair of sockets include projections which are received in an opening on the other member to enable the other member to pivot relative to the pair of sockets and the one member in substantially perpendicular plane.  At least one of the sockets is shiftable in a direction along the major axis of the member receiving the projections in order to reduce the maximum dimension of the pair of sockets and the member to permit the pair of sockets and the member to be accommodated within the housing.  When accommodated within the housing, the socket is shiftable into its operative position wherein both sockets substantially engage the wall of the cavity. The shiftable socket includes a locking member opening designed to accommodate a locking member for locking the socket with respect to the other member when the socket is in its operative position with respect to the other member.

Abstract: ABSTRACT OF THE DISCLOSURE         The collapsible safety element has a polygonal end and a star-shaped end which are interconnected by flat triangular sections.  The triangular sections are disposed relative to one another so that the points of the star-shaped end are in line with the corners at the polygon-shaped end.  Consequently, when the safety element is closed, the triangular sections extending from the star-shaped end are disposed in parallel relation to each other.  This improves and increases the sealing effect of the safety element at high pressure.

Abstract: A?-144 IMPROVED TUBE CUTTING APPARATUS                          ABSTRACT A ram driven tube cutting apparatus of the double cut type in which sections of tubing are suc-cessively severed from a continuous length thereof by a notching cut followed by a severing cut, includes improved mechanism for clamping the tubing during the cutting process.  A pair of opposed, complemental die jaws are mounted on slides controlled by spaced cam followers carried by the slides.  A reciprocating wedge cam engages and forces the cam followers apart to move the slides thereby closing the jaws on the tubing.  One of the cam followers comprises a roller mounted on an eccentric shaft which may be selectively rotated to adjust the clearance between the die jaws. The other cam follower is spring loaded toward the cam within a slide mounting provided in its slide and automatically shifts to an overload position to avoid damage to the mechanism when foreign objects become lodged between the die jaws.  Each of the die jaws consists of a pair of die jaw portions having spaced, opposed forces defining a slot through which  a severing blade may pass.  The die jaw portions are removably mounted on the slides by bolts anchored with trap nuts slidably confined within a T-shaped passageway  in the slides to permit adjustment of the spacing between opposed -faces of the die jaw portions.

Abstract: A MOBILE SPREADER UNIT          Abstract of the disclosure A mobile spreader unit comprises a tractor and a detachable hopper. The latter is defined by tapering front and rear walls and has a breadth permitting it to fit in between the rear wheels of the tractor. There is an elongate spreader opening in the bottom of the hopper, and an agitator adjacent to the mechanism driven by a roller to be brought into contact with one of the rear wheels of the tractor. Pivots at the front wall of the hopper are atachable to brackets at the tractor, and are located so the point of gravity of the hopper tends to tilt it away from the tractor. In its furthermost tilted position the rear wall will be substantially parallel to the ground, and the hopper may then be used to scoop up particulate material to be spread. A pressure fluid actuator raises the hopper to an upright position, in which finally the roller con-tacts the rear wheel of the tractor and drives the agitator.
