  • Patent number: 4087090
    Abstract: An amusement device is provided with an elongated upstanding transparent tube, closed at its top and bottom, and containing a suitable projectile, advantageously a ball. A launching means in the form of a pivotal lever is provided adjacent the bottom of the tube. Ball retaining slide members are positioned at spaced locations along the tube and are adapted to be digitally moved into and out of the interior of the tube. The ball normally rests at the bottom of the tube upon the launching lever. When the lever is depressed the ball is propelled upwardly in the tube and the user then tries to digitally insert a slide member for the purpose of catching and retaining the ball as it gravitationally drops through the tube.

  • Patent number: 4087581
    Abstract: Microspheric opacifying agents are provided by admixing an aqueous, partially condensed, aldehyde condensation product with an oily material containing an emulsifying agent thereby forming a water-in-oil emulsion, admixing an amphiphilic acid catalyst with the emulsion and polymerizing the condensation product to form discrete, substantially spherical, opaque, solid particles. Additionally, the solid particles may be separated from the oily continuous phase and admixed with water for the further removal of oil material, and thereby causing the formation of spherical agglomerates or "super particles" having a substantially greater opacity than the aforesaid discrete particles. The super particles are hollow, substantially spherical particles having substantially spherical, discontinuous walls composed of agglomerated substantially spherical particles.

  • Patent number: 4081981
    Abstract: Apparatus for forming pipe from an elongated metal strip including a supply reel for the strip, an elongated tubular carrier, an axle at one end of the carrier for supporting the supply reel and edge-forming means for bending the edges of the strip to join them in a helical fashion to form the pipe wall. In one embodiment, the supply reel is supported at one end of the carrier and the strip is guided through the carrier and out through an opening near the other end. The carrier is supported for horizontal rotation. Near the opening there are guide rolls arranged in a helical path so that the strip emerges through the carrier, goes through the guide rolls, and then goes through the edge-forming devices including profiling and rabbeting rolls, also helically arranged. A motor is mounted at that end of the carrier and a chain drive from the motor drives the profiling and rabbeting rolls.

  • Patent number: 4080813
    Abstract: A mounting plate having three knockouts for three bolt locations of a deadbolt lock is mounted behind a rectangular opening in the edge of a hollow door. A filler plate and a cover plate are provided to cover the unused ones of the knockouts. When no deadbolt lock is installed in the door, the entire filler and cover plates are used to substantially fill the rectangular opening. When a dead bolt is installed in the door, a knockout is removed to leave an opening at the proper location for the bolt to pass through. The deadbolt lock bore drilling is made on the selected centerline either by the distributor or installer. The filler and cover plates are broken along weakened separation lines and appropriate portions thereof are attached to the mounting plate to cover the unused knockout locations. An adjustable backset lockset mounting arrangement is mounted adjacent the rectangular opening to receive and support the lockset in either of two positions. Breakouts in the door are preformed.

  • Patent number: 4078317
    Abstract: A flight simulator having an operator console, a conventional television receiver and one or more transparencies which are overlaid on the face of the television receiver.Electronic signals, generated by circuits housed in the operator console, produce an illuminated display on the television receiver including movable symbols representing the simulated aircraft, and fixed symbols representing environmental features such as landing fields. Controls on the console permit an operator to "fly" the aircraft symbol from, around and to the fields. Two modes of operation are provided, one simulating cross-country flight and the other, employing an enlarged scale representation, simulating takeoff and landing conditions.The overlay includes other fixed environmental features such as mountains. The display is divided into two portions, one in elevation and the other in plan, with aircraft symbols being concurrently visible in each portion.

  • Patent number: 4076477
    Abstract: A plurality of extrusion dies are operated from the same source of heat-plastified polymeric material, e.g., from a single barrel extruder, via a distribution manifold which includes forwardly diverging flow passages each leading to a different one of the dies. The flow passages of the manifold have equal flow capacities and compensation for differences between the extrusion dies is accomplished by equipping each die assembly with a replaceable flow control insert, the inserts being so dimensioned that the pressure differential across each die assembly, including the insert, is the same.

  • Patent number: 4075782
    Abstract: A doll in which an illness symptom is created, a treatment is administered and in which the treatment removes the symptom. One symptom is a fever produced by closing a switch which heats the doll's forehead and moving a member near an orifice of the doll's body, the forehead temperature being recognizable by touch and the oral or other indication being detectable by a simulated thermometer. The treatment comprising insertion of a spoon or simulated pill to open the switch and restore the member. Measles (roseola) is simulated by closing a switch to illuminate translucent portions in the body, presenting the appearance of spots. Mumps is simulated by inflating portions of the cheeks and neck, treatment comprising moving a valve member to slowly deflate the portions. Tachycardia is produced by changing the speed of a motor which drives a heartbeat simulating device. Cough-like sound will be produced by recording devices.
