Gregory G. Davis - Anaheim CA

International Classification:

F42B 3304
F42B 3310

US Classification:

86 36

Abstract:

The present invention defines a precision primer-reloading assembly to be mounted in and operated by a suitable cartridge-reloading press. The assembly includes a tubular support-body member having a ram rod mounted therein so as to be positioned within the cartridge case at the time the primer is loaded. The support-body member is mounted to the reloading press above and in alignment with a primer-guide assembly which is mounted to the press ram of the reloading press. The guide assembly includes a guide base having a primer-guide pin. A coil spring is positioned on the guide base so as to engage the guide housing that is slidably mounted over the guide base, the guide housing being formed with a closed end having a centrally positioned recess. This recess is provided to support and align the cartridge case with the ram rod, whereby the primer can be loaded in the primer pocket of the case by means of the primer pin as the ram rod is activated. One or more shim members are provided to allow the primer to be selectively positioned at a predetermined location within the primer pocket.

International Classification:

B32B 306
B42F 300

US Classification:

428100

Abstract:

A flexible panel or sheet adapted for installation in a printer for separating the incoming blank paper web from the outgoing printed paper web. The sheet is wide enough to span (overlap) perforations in edge areas of the paper that are used to pull the paper web through the printer. By providing a physical separation between the incoming paper and outgoing paper it becomes possible to prevent uneven paper backups, misfeeds or uneven paper movement caused by tiny slivers of paper lodging or catching in the drive perforations when the webs come into contact with each other. The separator sheet is attached to the printer by two spaced-apart straps that extend from the sheet around a pre-existing crossbar in the printer. The straps lie in the general plane of the separator sheet to minimize the sheet thickness; cutouts in corner areas of the sheet accommodate the straps. The straps are of adjustable length to permit optimum positionment of the separator sheet.

Assignee:

International Classification:

G06F 1122
G01R 2702

US Classification:

324158R

Abstract:

An identification circuit for use in identifying at least two integrated circuits having the same logic function but different input/output characteristics, each circuit having first and second isolated power supply conductors. A unilateral current conducting circuit having an input and an output is coupled between the first and second power supply conductors via conductive jumpers in all but one of the identifiable integrated circuits. The conductive jumpers are removed for one integrated circuit family. The other integrated circuit families have unique combinations of a resistor and at least one serially coupled diode wherein a predetermined potential is required to induce current to flow therethrough for each family. The potential of the first power supply conductor is increased in predetermined steps until current flow is detected, or a predetermined maximum potential is reached. The combination of the presence or absence of current flow and the potential at the first power supply conductor associated therewith provide the identification of the integrated circuit.

International Classification:

H03B 512
H03L 500

US Classification:

331109

Abstract:

A voltage controlled oscillator circuit including an oscillator circuit having first and second terminals to which an external inductance is connected. A frequency control voltage (V. sub. F) is applied through a bias circuit to the second terminal for varying the center frequency. The oscillator circuit may have an AGC circuit or a modulation circuit connected to it. An output amplifier is connected with the first terminal and has an adjustable output impedance for matching the input impedance of a load circuit.

US Classification:

26714013, 188268, 29592

Abstract:

An apparatus and method for vibration suppression using a granular particle chain. The granular particle chain is statically compressed and the end particles of the chain are attached to a payload and vibration source. The properties of the granular particles along with the amount of static compression are chosen to provide desired filtering of vibrations.
