Granted: 1982-01-19
Abstract: ABSTRACT OF THE DISCLOSURE           A method is provided for producing a metallic article.  The method includes forming a mixture of metallic particles selected from the group consisting of platinum group metals, gold, silver and base metals, the metallic particles having a size falling within the range 1/2 to 50 microns, and particles of a thermoplastic material;  placing the mixture in a mold;  molding the mixture under pressure and at an elevated tempera-ture;  and removing the metallic article from the mold.  This method is a distinct improvement over the "lost-wax" process in that a separate casting mold is not required for each of the individual article products.  It is particularly adaptable for the fabrication of "cheap" items of jewellery, e.g., medallions, which are required to have a pleasing appearance but little intrinsic value.

Granted: 1982-07-13
Abstract: ABSTRACT          Signal correction apparatus for use in a video disc playback system wherein an FM video signal is recorded on the disc in an alternating sequence of light reflective and light non-reflective regions forming a plurality of substantially circular and concentrically arranged informa-tion tracks, and wherein the signal is recovered from the disc using an objective lens to focus a beam of radiation onto a selected track, as the disc is rotated with respect to the beam at a prescribed rate.  The objective lens has a limited resolving power, so the video signal recovered from the disc is increasingly bandlimited as the radius of the selected track decreases, thereby causing a variation in the relative amplitudes of the luminance and chrominance portions of the reproduced signal.  The signal correction apparatus operates to correct for such band limiting by detecting the amplitude  of the successive chrominance bursts in the recovered video signal and producing a corresponding gain control signal, and by controllably amplifying in accordance with the gain control signal the portion of the FM signal spectrum near the FM carrier, where the luminance informa-tion is primarily located, whereby a substantially constant relationship between the respective amplitudes of the luminance and chrominance portions of the video signal is achieved, regardless of the radius of the information track from which the signal is recovered.

Granted: 1983-08-02
Abstract: TEMPERATURE SENSING PROBE AND DISPOSABLE PROBE COVER            ABSTRACT      This invention relates generally to a tempera-ture sensing probe and disposable probe cover adapted for use with an electronic thermometer.  A disposable cover for an electrical probe is known, wherein the cover includes a thermally insulating plastic body formed together with a heat conductive metal tip. However, forming the cover with a body and tip portion of dissimilar materials is costly and increases the expense of employing the device.  Moreover, such ar-rangement generally has included an electrical probe having a spring biased probe shaft mounted for axial reciprocation, thereby adding further to the cost and complexity of the device.  The present invention over-comes these deficiencies by providing an improved probe and cover arrangement.  The temperature sensing probe includes a probe shaft rigidly mounted on a handle and having a temperature sensing tip at the distal end of the shaft.  A disposable cover is provided in the form of a unitary elongated tube constructed of heat con-ductive material and having an open proximal end arranged to slide  over the probe shaft and a closed distal end arranged to tightly engage the temperature sensing tip of the shaft in order to retain the cover on the shaft and provide a positive conduction of heat to the temperature sensing tip.  For the purpose of selectively ejecting the cover after temperature measurement, the probe handle includes a movable ejec-tion button for manually driving the cover forwardly with sufficient force to disengage the cover from the tight engagement with the temperature sensing tip.
