Abstract: CANADA                  FISH EGG SUPPORTING SYSTEM           Abstract of the Disclosure A system for supporting fish eggs including a waffle-patterned surface providing individual fish egg supporting apertures,  The apertures are in a noncircular form to permit the flow of fluids and gases around the egg supported in each aperture.  The apertures are spaced from one another a distance to permit the eggs resting in adjacent apertures to have a gap therebetween to prevent the fungus that might form on a dead egg in one aperture from spreading to an adjacent viable egg resting in the next aperture.  The system can include stackable trays which permit numerous eggs to be held in a small volume.  The apertures are of sufficient similarity in surface configuration to natural gravel beds to support the alevin in comfort to encourage maximum conversion of the egg yolk to fish tissue rather than wasting such nourish-ment on notion.  The trays can be stacked within a raceway with a porous membrane upstream of and adjacent to the stacked trays to distribute the flowing water evenly throughout the stack.

Abstract: ABSTRACT OF THE DISCLOSURE:     A mold assembly for continuous casting has a plurality of open-ended molds.  The mold assembly further has a cooling member which is common to all of the molds and co-operates with each mold to define one or more cooling passages therewith.  The cooling member, which is provided with one or more pairs of coolant inlet and outlet bores, is in the form of a cooling jacket or in the form of a back-up plate depending upon whether the molds are tube molds or plate molds.  The mold assembly is rotatably mounted on a mold table having a casting location at which a mold is positioned during a casting operation.  A coolant supply and coolant dis-charge conduit are arranged in the mold table adjacent the casting location.  In operation, one of the molds of the assembly is positioned at the casting location with the remaining molds being in standby positions.  At least one pair of the coolant inlet and outlet bores in the cooling member is aligned with the coolant supply and discharge conduits in the mold table.  Molten metal is introduced into the mold to form a continuously cast strand.  When the mold is to be changed, the introduction of molten metal into the mold is terminated.  The trailing end of the strand is with-drawn from the mold, the supply of coolant to the mold is discon-tinued, and the mold assembly is rotated to bring another mold into the casting position. In this manner, substitution of one mold for another may be accomplished rapidly and without removing the supply vessel for the molten metal.

Abstract: ABSTRACT      A hand-held electronic device provides for simultaneous operation of a sports-action game by two operators.  A housing contains a display panel and two seven-segment displays that provide status information. Operational circuitry is contained in the housing that controls the seven-segment displays and the display panel.  Offensive and defensive control boards are provided on either side of the display panel to enter offensive and defensive commands into the operational circuitry.  The display panel includes five stationary offensive-player positions and a goal position, and an LED is provided at each of the positions to indicate that the goal has been reached or that the offensive player is in possession of a game object.  Furthermore, pass paths of LEDs are provided between pairs of the offensive players, and shot paths of LEDS are provided between some of the offensive players and the goal.  The operational circuitry simulates passes by consecutive illumination of the LEDs in a pass path, and it sim-ulates shots by consecutive illumination of LEDs in a shot path. LEDs are also provided in a defensive-player path and in a further path that simulates a goalie or a target, depending on the game being sim-ulated. Coincidence between the defensive player and the game object is detected by the operational circuitry, and successful or unsuccessful shots and passes are simulated as a result, depending on the game being simulated.

Abstract: VERTICAL SYNCHRONIZATION SYSTEM               ABSTRACT OF THE DISCLOSURE            A two-mode digital vertical synchronization system is described for controlling the phase synchroniza-tion of vertical scan in a television receiver.  In one mode, the system searches for incoming vertical sync pulses which occur during a wide sync "window".  Sync pulses received during that window are utilized to initiate vertical scan.  When the received sync pulses are in time-coincidence with an internal control signal generated at a standard line/frame rate, the system switches to a narrow window mode of operation.  Vertical sync pulses received during a narrow sync window continue to initiate vertical scan.  When a lack of time-coincidence between received vertical sync pulses and the control signal occurs for a predetermined interval, the system reverts to its wide window mode.  Preferably, the locally generate  control signal has a time duration sufficient to permit detection of coincidence between itself and a typical non-standard vertical sync pulse to hold the system in the narrow window mode, thus preventing oscillation between the narrow and wide window modes.

Abstract: Abstract Both the position and shape of the solidification front in molten metal passing continuously through the horizontal solidification chamber of a mold body are precisely controlled in the invention by establishing a cooling probe insertion pattern in which some of the probes are inserted into cooling bores in the mold body to greater distances that others.  Specifically, establishment of a solidification front characterized by a liquid/solid isotherm that is substantially symmetrical across the chamber is achieved by progressively increasing the cooling probe insertion distance from the bottom to the top of the mold body.  Premature, asymmetrical solidification on the bottom of the chamber is effectively minimized and reduces hot tears, fissures and other surface defects in the casting.

Abstract: ABSTRACT OF THE DISCLOSURE        A working pit with an articulated tool arm assembly is provided for an automobile assembly line.  A tool carried by the arm assembly is used to perform assembly operations in an automo-bile moving either longitudinally or transversely along the line. The articulated arm is mounted on a trolley which is movable longi-tudinally of the working pit along tracks adjacent a side wall of the pit.  The tool arm can pivot horizontally toward and away from the pit wall and can pivot vertically to enable a tool holder at the end of the arm to move from a position at or below floor level to a position in the path of an automobile body moving along the assembly line above the pit.  The tool holder enables the tool to rotate through a path of 360° and to tilt.  The articulated arm is especially designed for use with a nut runner to tighten nuts and bolts underneath the automobile body, but can also be used with other tools.  A nut retaining wrench or work holder can be carried by the tool holder and mounted for movement toward and away from the nut runner.
