Abstract: A toy basketball game having a court floor, a stand attached to the floor for a backboard ring and net, an articulated player and a movable base for the player. The player contains a compressible spring in one leg which is held compressed by a lever on the player's leg, which lever releases the spring to cause the player to jump and to raise its arm having in its hand a releasable ball, which ball releases when the player's arm contacts the ring of the basketball basket. The base has a rotatable wedge-shaped plate for changing the angle of jump of the player so as to cause the player to be projected toward the ring from any location of its stand on the court. If desired, the ring and the arm of the player may be provided with adhering roughened surfaces so that the player can hang on the ring.

Abstract: A fluid pressure system comprising an electric motor-driven pump for maintaining a predetermined pressure range in a system, including a remote solid-state encapsulated triac motor control circuit having a micro pressure sensor switch in the outlet duct from the pump. For example, this control device includes a special nipple for installation in a water well casing for maintaining a given range of water pressure in a system supplied by the well.

Abstract: The disclosure comprises a tray mountable under the floor of a vehicle, which tray contains an extendible ramp mechanism. This mechanism comprises a ramp and a driving panel for the ramp. The ramp is fulcrummed intermediate its ends on the outer ends of parallel arms extending from the driving panel. Also in the tray, as part of the driving mechanism, are a pair of parallel toothed belts driven by a reversible rotating motor, which belts are attached to the driving panel for extending and retracting the ramp from the tray. Mounted under the driving panel is a reciprocating motor connected by a crank arm to a shaft having additional crank arms pivotally connected to the underside of the ramp adjacent the driving panel. When the ramp is fully extended, the reciprocating motor tilts the ramp so that its inner end is moved upwardly to be flush with the floor of the vehicle. Simultaneously, the outer end of the ramp contacts the ground.

Abstract: Disclosure concerns a portable drawing toy comprising an openable rectangular box having manual rotatable knobs in the two lower opposite corners, which knobs move by strings and pulleys a horizontal and a vertical bar orthogonally with respect to each other. At the intersection of these bars is a socket for one of a plurality of different colored marking pens. A cover for the box comprises a framed window with flanges for holding a translucent paper on the underside of the window so that when the cover is closed the marker pen contacts the paper and rotation of the knobs causes the pen to draw lines on the paper, which lines can be viewed through the window. The translucent paper can be changed for retaining the drawing made thereon, and a magazine for different colored pens is provided in the base of the box.

Abstract: An improved method and apparatus for cleaning liquid-carrying hoses, and the like. A suitable cleaning solvent is passed under pressure through the hose. The pressure of the solvent delivered to the hose is measured and used to control the pressure of compressed air mixed with the solvent to maintain a turbulent flow of a predetermined mix ratio for various solvent pressures. The turbulent solvent/compressed air mixture increases scrubbing of the hose to reduce the cleaning time and the quantity of solvent required to clean the hose.

Abstract: The disclosure concerns a peripherally-toothed cutting wheel for parallel series of intermeshed cutting wheels, such as employed for the shredding of tires. Each cutting wheel comprises three congruent disks axially bolted together in which the two outer disks have hardened rectangular teeth radially bolted thereon. The inner sides of these teeth abut the opposite surfaces of the intermediate or third spacer disk peripherally congruent with the two outer teeth-mounting disks. Each rectangular tooth comprises a block of hardened material, such as steel, and may be backed up by a second congruent rectangular block providing an outer wearing surface in addition to the outer side surface of the tooth itself.

Abstract: Steps are convertible into a platform of an elevator for wheelchairs such as installed in vehicles and buses, during which conversion a barrier is automatically raised from the bottom step to be at the outer edge of the platform. The barrier is operated by an extensible link under the bottom step, which link is connected between the barrier and a crank arm keyed to an oscillatible transverse shaft under the inner part of the bottom step. Two additional crank arms are keyed to the ends of this shaft and are connected to a frame for a step or riser to oscillate said shaft when the steps are extended and unfolded into their platform position. The extendible link extends the barrier into a ramp when the platform is in its lowest position for access by a wheelchair. Reciprocating motors such as hydraulic pistons extend, retract, fold and unfold the panels that form the steps and their intermediate risers.

Abstract: This invention concerns a system for insuring and accurately controlling the turbulent flow of a pressurized mixture of a gas and a cleaning fluid for purging and cleaning ducts. The pressures of cleaning fluid and the gas are continuously sensed and transduced into electrical signals for controlling valves for the pressurized gas to maintain and insure its pressure at a predetermined amount relative to the pressure of said cleaning fluid, so that when the gas and fluid are mixed in a turbulator, turbulent flow is insured. The improvements of this circuit include a pressure sensor transducer for sensing the pressure of the input of the air to the turbulator and feeding it back to the main air pressure transducer for accurately maintaining a predetermined ratio between the gas and cleaning fluid pressures within less than about 1 psi in at least pressures of 150 psi. A pressure warning signal indicates when the gas and/or cleaning fluid pressure is too low to produce effective turbulent flow.

Abstract: The disclosure concerns a hard multi-ply laminate, at least two of the plies comprising primarily wood fibers compressed with a plastic, and an intermediate ply of a different chemical composition than the wood fiber plies, and top and bottom plies of substantially the same physical performances to avoid warping. An adhesive is applied between each of the plies and all the plies are compressed to form a hard laminate. An edge of the resulting board is shaped to form an artistic configuration, and the edges are coated with a moisture barrier. Thus the resulting hard laminate boards with a sculpted edge can be used directly for table and desk tops, shelving and the like without the addition of an edging strip.

Abstract: The framed printout is connected to an expendable core for a high-pressure die casting die, which printout is spaced outside and surrounds the cavity in the die. The casting and its cavity in the die has at least one open side into which the core is positioned, such as to form a jacket around a cavity in a casting. The die has in its parting surface a pocket for seating the frame of the printout and its connections to the core, which pocket is spaced from and is outside the casting cavity in the die.

Abstract: This disclosure concerns an expendable core for molds such as die casting dies, which core has a central aperture which may be elongated. The outside of this core is provided with a plurality of parallel grooves across the elongated sides of the core parallel to the aperture. These grooves may have corresponding ribs in the central aperture. One and the common end of each of these grooves is provided with a bridging web integral with the core for reinforcing and strengthening the core. The opposite end of the core from these webs may be provided with a printout portion also integral with the core by which the core is supported in the mold or die.

Abstract: The special angular fixture or jig for mounting a casting, such as a die cast engine block, resiliently holds the casting both inside and outside of a cabinet, in which cabinet the casting is high-frequency-vibrated for removing an expendable and disintegrated core, such as of sand, from the casting. The fixture is so located with respect to the door to the cabinet so that when the door is closed, the casting on the fixture is resiliently held between the closed door and a vibrating plate of a high-frequency vibrator. Specifically, the fixture disclosure is L-shaped and mounted on cushioned legs to a downwardly open door to a cabinet, which legs permit the casting to be urged against a vibrating plate mounted in the cabinet when the door of the cabinet is closed. The cabinet collects the particles of the disintegrated core which are vibrated from the casting.

Abstract: The partition wall units include panels with mitered tubular frame strips, posts, raceways which also can be adapted for baseboards, and covering edge strips. Most of these units include a groove along an outer edge into which are removably mounted interlocking or interhooking key members having uniform C-shaped cross-sections. These C-shaped cross-section key members on adjacent edges slideably engage each other to form cylindrical apertures between the two interhooked C's. Self-tapping screws are then screwed into these cylindrical apertures near the ends of the adjacent strip for locking the two units together. The substantially rectangular tubular frame strips around the panels have mitered joints which are connected by a pair of longitudinally complementary angle blocks with complementary grooves along their legs between their abutting surfaces.

Abstract: A sealed connection for a sleeve and jacket for protecting a molybdenum electrode mounted through the wall of an electric glass furnace. Around the electrode in the wall is a stainless steel sleeve coated on the inside with a fused alumina and having an outwardly extending flange at its outer end which engages the outer wall or shoulder in the aperture in the wall through which the electrode extends. The flange has an axially outwardly extending rib of V-shaped radial cross-section which seats and centers in an annular V-shaped groove around the inner end of a water jacket that surrounds the electrode outside the furnace. Refractory sealing gaskets are placed between the flange and the wall of the furnace and in the cooperating grooves and ribs of the sleeve and water jacket. The sealed cylindrical annular space around the electrode between it and the sleeve and the jacket is filled with nitrogen to prevent oxidation of the molybdenum electrode.

Abstract: The core box has a drag and a cope forming a mold cavity for forming a sand base core. This sand is injected into the cope and the air in the cavity is vented through vents remote or spaced away from where the sand is inserted. These vents are usually in the drag, but may also be in the cope. In each vent adjacent the cavity is a cylindrical cup-shaped plug having slotted perforations in its bottom narrower than the diameter of the sand grains. The diameter of this perforated vent plug is at least 50% greater and preferably at least twice the width of the cavity, slot, or groove at the vent whereby air can be vented along the cavity. Furthermore, the plug having the perforations may be contoured to the groove or that portion of the cavity in which the vent is located so that air can also be vented from the sides of the cavity or groove.

Abstract: An open-top, heat-resistant container, such as a molten metal ladle for filling the shot sleeve of a die casting machine, having a block rigidly attached to the ladle and partly submerged into the surface of the molten metal in the container or ladle for reducing a major portion of at least half of the area of the exposed surface of the molten metal in the container. The block may be vertically adjustable for varying the amount of immersion into the molten metal when the predetermined amount of molten metal retained in the container has been reached by flow over a weir edge of the container or ladle. A fraction of a centimeter difference in level of molten metal in the container multiplied by the exposed area of molten metal in the container can amount to a kilogram difference in the molten metal measured by the tilt and weir of the container or ladle. Thus, the less the exposed area of the surface in the container, the more repeatable the measured amount of molten metal can be poured from the container.

Abstract: This disclosure concerns dies for die casting machines having a stationary or cover die and a movable or ejector die which has a movable slide mounted thereon. A tapered trough is provided across the slide and into opposite sides of the movable die, and the cover die is provided with a floating wedge that fits into the full length of this trough for positioning and locking the slide with respect to the movable die on which this slide is mounted. The floating wedge may be held in the cover die by flanges on the wedge which loosely fit in grooves in the cover die. The tapers on the wedge and the sides of the trough are complimentary for locking the movable die parts together when all the die parts are closed for filling the cavity formed by the die parts with molten metal.

Abstract: A pair of parallel slalom posts connected by a flag, which flag is connected by an elastic strip with one of the posts, and the other post is provided with a tilting joint. Thus, if a skier touches the post with the tilting joint, the post can bend without damage to the flag.

Abstract: A stationary die for a horizontal die casting machine has an oscillatable molten metal injector below the die that oscillates from an acute angle outside the die for filling with molten metal to an acute angle under the die or injecting the molten metal into the die. The stationary die has an annular docking block at the same acute angle to the horizontal as the axis of the shot sleeve under the die. The edge of the aperture at the outer end of the docking block is adjacent to and substantially in the plane of the parting surface of the stationary die so that the docking block per se projects outwardly from the surface. Correspondingly, the adjacent parting surface of the movable die is provided with a cavity for fitting this projection of the docking block, but since the surfaces of this docking block are at convergent acute angles, they provide no restriction to the movement of the movable die.
