Abstract: The dislosure relates to fluid flow control devices, particularly for use in connection with valves used in the control of fluids under high pressure. In the new structure, the valve trim includes a novel and advantageous form of flow restrictor, which serves to limit flow velocity and which causes the fluid pressure to be reduced in a sufficient number of discrete stages to minimize noise and cavitation. The new flow restictor comprises an axial stack of annular discs, each provided with a plurality of annular baffle ribs projecting from its opposite end faces. The annular baffle ribs on one side of the disc are slotted along a number of equally spaced radii, and the ribs on the opposite side of a disc are similarly slotted, but along radii offset from the first set of radii. When a series of these discs is assembled in a stack, downwardly facing ribs of one disc fit between upwardly facing ribs of a disc next below, providing a series of annular passages interconnected by radial slots.

Abstract: A process for producing VLSI (very large scale integrated) circuits employs techniques of self-aligned gates and contacts for FET devices and for both diffused conducting lines in the substrate and polysilicon conducting lines situated on isolating field oxide formed on the substrate. Mask alignment tolerances are increased and rendered non-critical. The use of materials in successive layers having different etch characteristics permits selective oxidation of only desired portions of the structure without need for masking and removal of selected material from desired locations by batch removal processes again without use of masking. There results VLSI circuits having increased density and reliabilty. The process allows the simultaneous doping of two or more regions resulting in uniformity of device characteristics.

Abstract: Disclosed is a firing mechanism for revolvers having a firing pin and a limit pin each movable by the hammer to engage the cartridge and cooperable to limit the extent of penetration of the firing pin into the cartridge.

Abstract: A simplified combination animal call has a casing divided into identical upper and lower half sections held together by a securing elastic band. Symmetrical channels of different widths spaced longitudinally along half sections provide airways through the casing whose openings act interchangeably as mouthpiece openings along one side of the casing and sound-emitting bells on the opposite side. Air blown through any such airway vibrates a second elastic band which spans each airway to produce an animal-like sound. Multiple airways of different widths make available several different pitch ranges at once. Changing either the size or tension of the vibratory elastic band changes the pitch that is available at each slot. Finally, the pitch produced may be dynamically varied either by changing the tension on the vibratory elastic or by compressing the mouthpiece side of the casing while the device is in use.
