  • Patent number: 4395155
    Abstract: A reflective highway marker mounted within an elongated groove formed in a highway pavement, the groove extending longitudinally of the highway and exposing the reflective highway marker to the headlights of oncoming motor vehicles when their approach distance from the reflective highway marker is adequate for highway guidance purposes. The reflective highway marker is provided with a reflective surface which is slightly inclined from the vertical and oriented to reflect back to the eye level of the average driver of an average vehicle a beam of light which emanates from the level of the average headlight on an average vehicle. The elongated groove is substantially narrower than the width of the narrowest motor vehicle tires conventionally in use to prevent destructive contact between the tires and the reflective highway marker.

  • Patent number: 4333557
    Abstract: For use in connection with coin-operated vending machines or the like having a coin lock-out coil or solenoid which accepts or rejects coins depending on whether the sole solenoid is energized or de-energized, a detector circuit comprising electromagnetic beam emitters, electromagnetic beam sensors and circuits for interpreting the received signal and determining whether the coin lock-out solenoid is to be energized, thereby accepting a coin, or de-energized, thereby rejecting a coin. The emitter is directed toward an incoming coin slot with the moving coin reflecting the beam in a particular pulsed sequence depending upon the surface characteristics and contours of the coin. The beam sensor is so located as to pick up the pulsed reflected beam from the surface of the coin, which reflections are amplified, timed and counted, and analyzed to accept or reject the coin through energizing or de-energizing the coin lock-out solenoid.

  • Patent number: 4304065
    Abstract: A walking hand puppet in the figure of a walking or crawling land or sea animal, bird, insect or the like, comprising a body with finger-insertable appendages, and a non-functional glove on the body, said glove having a passage formed therein through which a hand is insertable to insert the fingers into the appendages and to manipulate them in simulation of walking or crawling. The presence of the glove creates the optical illusion that the hand is received and held therein, which raises the question of how the appendages are manipulated.

  • Patent number: 4226045
    Abstract: A stackable toy comprising a doll having a centrally disposed, vertically movable pin, said pin being recessed within the doll when in retracted position and extending upwardly from the doll when in projected position, a socket being formed within the doll below the pin. The projected pin of one such doll is adapted to engage the socket of a second such doll to assemble the two dolls in stacked positions. Each doll is also provided with angularly disposed pin-shaped limbs, e.g. arms, and these limbs are equally engageable with a doll socket. A plurality of dolls made in accordance with this invention may be stacked by means of their respective centrally disposed pins as well as by means of their respective pin-shaped limbs. Various alternative means are provided for extending and retracting the centrally disposed pin. In its simplest form the pin is manually movable into either projected or retracted position.

  • Patent number: 4204559
    Abstract: A line tap valve for tapping refrigerant lines of refrigeration and air conditioning systems, said line tap valve having a housing which is adapted to be clamped to a refrigeration line, said housing having two non-aligned but communicating valve bodies or chambers, a line piercing valve in one valve body or chamber and a service valve in the other valve body or chamber, said line piercing valve and said service valve being independently operable, to control the flow into and out of the refrigerant line. The service valve is removable and replaceable without refrigerant leakage when the line piercing valve is in closed position. The line piercing valve is retractable from the refrigerant line to provide an unimpeded flow therethrough when the service valve is in closed condition.

  • Patent number: 4184786
    Abstract: Method and means for protecting earth dams from failure caused by overflow or internal (tunnel) erosion. The invention provides a barrier between the dam and the impounded water in the form of a water-impervious covering for the vulnerable surfaces of the dam. At the least the covering should sheathe the top and upstream face, but better protection is provided by extending the covering to the downstream surface. The covering is flexible to conform to the contours and surface irregularities of the dam, and anchoring means are provided to secure the covering to the dam and to prevent or minimize seepage.

  • Patent number: 4168836
    Abstract: An internally illuminated spindle for record player turntables, said illuminated spindle being adapted to guide and facilitate placement of disc records on the turntables. Secondary internal illumination may also be provided in the spindle to illuminate the label area of the disc records. The internally illuminated spindle is constructed to minimize scratching of the disc records in the event of misalignment of the records relative to the spindle when they are placed on the turntable. This construction is also feasible in the absence of illumination.

  • Patent number: 4157140
    Abstract: Retractable clamping means for clamping sheet laminates and other forms of work upon the work supporting surface of a table, said clamping means being retractable to inoperative storing position below said work supporting surface, and being movable to operative clamping position above the work supporting surface. In the preferred form of the invention, the clamping means operates upon two adjacent sides of rectangular workpieces in each clamping operation, and the workpieces are rotated 180 degrees on the work supporting surface to enable the clamping means to operate upon the remaining two sides of the workpieces. To facilitate handling of the workpieces, the table used in conjunction with the clamping means embodies air or other fluid float means.

  • Patent number: 4134420
    Abstract: A faucet valve for kitchen sinks, bathroom washbasins and like applications, said faucet valve being adapted to be made of molded plastics, having relatively few operative parts, and designed to minimize the stresses of assembly and use. The invention has two principal features: the first is the use of a ratchet interlock between the bonnet of the valve and the cover plate of the sink or washbasin, said interlock being oriented to allow the bonnet to be rotated in one direction relative to the valve body in order to thread the bonnet into engagement with the valve body, and to prevent the bonnet from rotating in the opposite direction relative to the valve body when the valve is in use; and the second is the use of a self-centering valve closure member in the form of a spherical ball mounted within a spherical socket with sufficient clearance between them to enable the ball to float relative to the valve seat.
