Abstract: TAPE ASSEMBLY          ABSTRACT         A tape assembly for use with an ullage measuring device for the measurement of ullage of a liquid in a storage tank, has one end adapted for connection to a detection device and its other end adapted for connection to a tape assembly payout device. The tape assembly comprising an outer jacket of material impervious to the liquid under measurement and electrically non-conductive.  A pair of spaced electrically conductive elements is contained within the outer jacket.  A tape having measuring indicia thereon is also contained within the jacket and is juxtaposed to the electrically conductive elements but insulated therefrom to form a composite tape formed of the pair of conductive elements and the indicia tape.  The assembly permits more accurate measurement than has hitherto been possible.

Abstract: ?     APPARATUS AND METHOD FOR INJECTION MOLDING OF ELONGATED               HOLLOW PLASTIC CONTAINER WALLS     ABSTRACT OF THE DISCLOSURE           Straight walled hollow containers may be molded without taper, according to the present invention.  Two mold halves, when brought together define a cavity configured to the outer wall of a hollow plastic container to be-injection molded, and also an opening at one end of the cavity to enclose the stem of a core defining the inner wall of the hollow plastic container.  When the core is disposed in the cavity, it is centered within the latter.  Thereby a space is provided between the inner walls of the mold halves and the outer wall of the core to receive plastic material in-jected under high pressure through a sprue, also defined by the-inner walls of the mold halves.  After injection, the plastic is cooled to just below the softening point of the plastic.  At this point separation of the mold halves sur-rounding the outer portion of the core, is commenced and a force is applied to initiate withdrawal of the core from between the mold halves. Simultaneously therewith, air under pressure is injected into the space between the innermost end of the core within the cavity and the adjacent end of the cavity.  Thereby, the air under pressure is forced be-tween the core and the surrounding soft molded plastic to act as a bearing or lubricant to enable the core to be com-pletely withdrawn from the cavity without damaging the molded container.

Abstract: CANADIAN PATENT APPLICATION ABSTRACT OF THE DISCLOSURE A suspension system for a double-axle vehicle has been developed which allows load-sharing up and down movement of the axles to occur in a rectilinear manner so as to cope with road surface irregularities, such as potholes. The rectilinear manner of the movement ensures that the axles do not twist and, for example set up driveline vibration in a driven axle. The forward end of the leading spring and the trailing end of the other spring are each carried by a cranked rocker. The intermediate ends of the springs are interconnected by a further rocker. A torsion shaft links one axle to a rocker mounting point, and the free arms of the two cranked rockers are connected by a rod which causes the cranked rockers to move synchronously as the springs move up and down, thereby ensuring rectilinear movement of the springs. -1-

Abstract: Abstract A sieve device for separating a mixture of particulate material in components of different sizes, comprising a perforated sieve surface that rotates around a central, vertical shaft, said sieve surface having the shape of a hollow, truncated cone casing with a downwardly directed top, on which an imperforate distributor cone with an upwardly directed top has been amounted in the middle, of which distributor cone the basis connects to the sieve surface, whereas the supply of the mixture to be separated takes place via a central supply tube placed above the distributor cone, whereas the removal of the coarse component takes place near the circumference of the sieve surface. The novel device comprises at least one additional sieve surface, of which the diameter of the perforations differs from that of the former sieve surface, which additional sieve surface is displacable between a non operative position, in which it is removed from the former sieve surface and cannot receive mixture, and an operative position, in which it is placed on top of the former sieve surface and can receive the supply of mixture.

Abstract: Abstract of the Disclosure A valve and particularly a safety valve for use in controlling flow from a well in which an external motor is utilized to shift the actuator of a valve such as a ball resilient means between the crosshead attached to the motor and the reciprocating actuator. The actuator is latched when the valve is in the open position so that it cannot be moved to closed position except by movement of the reciprocating motor. The valve and seat assembly are designed to be re-placed as a unit and can be fabricated as a subassembly with the valve in exact open alignment when the reciprocating actuator is in full valve open position as determined by a stop against which the valve member bottoms.      The valve may have its actuator moved beyond the normal reciprocating range for opening and closing of the valve member to permanently lock the valve member in full open position without hindering further reciprocation of the actuator so that it can be used as a control for a secondary valve. The housing and actuator are provided with latch means and a secondary valve with a secondary actuator are landed in the housing and in the actuator so that reciprocation of the actuator then moves the secondary valve between open and closed positions.
