  • Patent number: 4498635
    Abstract: A machine for dispensing dry and moist materials including those which are self-adhering and/or compactible or which tend to agglomerate comprising a material dispensing chute formed at its sides by horizontally reciprocating, expanded metal grid plates which engage and separate material from adjacent material pressing thereagainst for passage through the grids of the plates and metered depositation onto articles or products passing therebeneath. The grid plates have horizontally spaced, downwardly converging upper portions forming a V where the majority of material is separated and horizontally spaced, parallel lower portions forming a narrow transverse width channel which prevents material from loading up between the grid plates in the V, such giving the chute a generally Y-shape in transverse cross-section.

  • Patent number: 4498036
    Abstract: A method of adaptive control for use in a controlled system having an adjustable forward loop gain and a control system apparatus for carrying out the method are disclosed. The control system measures the value of a parameter which is to be controlled and generates an error signal by comparing the measured valve of the parameter with a desired valve. The error signal is squared and the time derivative of the squared error signal is obtained. The control system compares the length of time that the derivative so obtained has a positive value to the time it has a negative value to obtain a gain control signal, and applies the gain control signal to the forward loop gain. The gain control signal reduces the adjustable forward loop gain until a preselected margin of stability in the controlled system is obtained.

  • Patent number: 4487421
    Abstract: A self energizing pipe gasket includes a base and arm configuration projecting therefrom which cooperates with the base when pipe sections are assembled to cause the lip or sealing edge of the arm to kick away or distend toward the sealing surface of the pipe. To facilitate this action a harder insert is provided in the base in the form of a reinforcing ring providing a less compressible surface for the arm to react against. The ring also stiffens the gasket making it more difficult to dislodge upon assembly of the pipe sections enabling higher compression forces and assuring that the gasket does not go under or below the minimal compression requirements to form a sound flexible yet fluid tight seal.
