Abstract: This invention provides a high speed catadioptric objective system of F/1.2. The lens system comprises, in accordance with the advance of the light rays, a front or first single lens, a main mirror lens, a counter mirror and a field lens system. The counter mirror is mounted in front of the front lens in order to achieve a short overall length and a good correction of sphero-chromatic aberration. The counter mirror may serve as a focussing element or it may be fixedly mounted to the front lens. The present lens system is distinguished over similar prior art systems by its overall length, which has been reduced by 30 percent, sunshade included. The same type of glass is used for almost all lenses of five preferred embodiments in order to eliminate the secondary spectrum and to enable the objective to be used within a very broad spectral range. An almost perfect correction of aberrations has been achieved with only spherical element faces, thus the systems are suitable when maximum image quality and speed are required. They are useful also for low light level and IR spectral range applications.

Abstract: Greater positioning tolerance is permitted in inductively coupled transmitter and receiver tuned circuits by achieving critical coupling therebetween. Critical coupling at a predetermined distance is obtained by selecting the appropriate quality, Q, of the tuned circuit, whereby the quality of the transmitter tuned circuit is preferably three times larger than the quality of the receiver tuned circuit. In a transcutaneous signal transmission system the critical coupling is realized by adjusting the spacing of the coils of the tuned circuits whereby the output impedance of the transmitter decreases to one-half the output impedance with no coupling.

Abstract: A multistage piston assembly is provided in apparatus for stuffing large meat articles in flexible tubular food casing. The piston assembly is mounted in longitudinally axial alignment with the article-loading chamber and stuffing horn and includes a first stage piston and a second stage piston coaxially mounted inside the first stage piston. During the first stage of operation, the two pistons move together to force the meat article through the article-loading chamber and into the stuffing horn. The second piston is then actuated to force the meat article through the stuffing horn and into the food casing. In order to prevent loss of liquid from the meat article during the stuffing operation, the two pistons are constructed so that they fit snugly inside the loading chamber and stuffing horn with minimum clearance and also are made to be substantially coextensive in the longitudinal direction with both the chamber and horn.
