  • Patent number: 4925423
    Abstract: A fabric doll constructed in the shape of a "cut-out" paper doll and having certain resemblances to aesthetic features thereof. The doll is assembled in a laminate configuration having outer layers of bonded fabric and an interior pad of a polyester fiber cushion. A stiffening stay is secured in the neck region of the doll for providing rigidity and preventing the head of the doll from flopping over as is conventional with paper dolls and the like. Securement hook and loop strips are also utilized on the frontal surface of the doll for facilitating attachment of play clothes. In this manner, a simple and inexpensive structure closely resembling a paper doll but in a reuseable and washable configuration is provided for the benefit and enjoyment of a small child.

  • Patent number: 4926399
    Abstract: A transducer mounting system for permitting the remote pivotal actuation of an underwater signal transducer. The mounting bracket permits a wide variety of transducers to be mounted upon a conventional trolling motor and remotely actuated by an operator in the boat. Actuation of the bracket directs the transducer of a conventional fish locator or depth finder of the acoustic variety for locating fish or other objects therearound. By securing the bracket to the trolling motor, one axis of orientation of the transducer is automatically indicated by the orientation of the trolling motor. Concomitant angulation of the bracket and transducer affixed thereto will thereby permit the operator to precisely locate desired objects such as fish in the direction indicated by the trolling motor.

  • Patent number: 4921048
    Abstract: A programmable system for controlling the operation of a plunger completion oil or gas production well to optimize production from the well. The controller operates one or more motor valves controlling the well in accordance with programmable values of off-time, on-time and exhaust-time. The controller monitors whether or not a plunger arrival signal is received on each cycle of intermitting the well and changes either the off-time or the exhaust-time for the next cycle in response thereto. In oil well mode, the off-time is decreased slightly for each cycle following a cycle in which plunger arrival occurred and increased slightly for each cycle following one in which it did not. In gas well mode, the exhaust-time is increased slightly for each cycle following a cycle in which plunger arrival occurred before on-time expired and decreased slightly for each cycle following one in which it did not.

  • Patent number: 4907650
    Abstract: A wellhead for a polished rod pumping unit to provide emergency closure of the bore through the wellhead in the event of breakage of the polished rod. The valve assembly includes a flapper valve mounted on a swivel pin for movement between a vertical open position and a horizontal closed position across the wellhead bore. The flapper valve is spring biased toward the open position. A well pressure responsive cylinder and piston assembly is mounted on the side of the wellhead with an operating rod into the wellhead against the flapper valve to move the valve from the open position to a horizontal closed position. The piston is exposed to well pressure on the one side urging the piston outwardly to the valve open position and a spring engages the piston on the opposite side biasing the piston inwardly toward the valve closed position when well pressure is not sufficient to keep the spring compressed. One form of the wellhead includes a packing assembly for sealing around the polished rod.

  • Patent number: 4899508
    Abstract: A building system integrating the combination of aluminum and steel structural elements for the efficient assembly of stone and glass panels in a curtain wall system which is conspicuous for its lack of a grid appearance. A plurality of discrete steel clips are utilized for securing stone panels to supporting mullions. A plurality of aluminum members are secured to structural mullions whereby glass may be mounted thereto. The stone and glass panels are sealably secured adjacent one another while a glazing adapter is constructed for assembly over the structural mullions there behind. A splice facilitates mating engagement of the aluminum mullions to permit relative movement therebetween. In this manner, both steel and aluminum may be utilized most efficiently for the assembly of stone and glass panels in a curtain wall system with improved structural and aesthetic qualities.

  • Patent number: 4864480
    Abstract: The operating process is based on the existance and cooperation of at least six functional units (64, 65, 66, 67, 68, 70), whereby the functional units (65, 66, 67) have a monitoring and control function. Functional units (64, 68, 70) together form the pause and frequency control circuit. Functional unit (65) monitors demagnetization of the transformer (2), functional unit (66) controls the time-averaged output current and functional unit (67) controls the output voltage of the switching controller. Functional unit (64) forms the voltage time-integral of the input voltage and functional unit (68) determines the target value of this voltage time-integral according to the pause duration determined. The process can be extended to monitoring the input voltage for the overshooting of a maximum value by a functional unit (71) and for under-shooting of a minimum value by a functional unit (72).
