Abstract: ABSTRACT            A tangent spin furnace providing a combustion chamber of metal which is unlined with any refractory material but whose temperature is maintained below the self-destruct level by combustion air being introduced into the combustion chamber between a plurality of slats defining the combustion chamber and disposed in space relation to each other so that they define longitudinal slots.  Thus there are slots for the introduction of combustion air between the slats so that a sweep of combustion air is maintained peripherally inside of the combustion chamber over virtually the entire inner surface thereof.  Without refractory material lining the combustion chamber overheating is avoided by the cooling effect of the sweep of combustion air.

Abstract: METHOD OF PACKING COLLECTED OBJECTS AND PACKING STATION THEREFOR. ABSTRACT OF THE DISCLOSURE This invention relates to a method of packing collected objects having different shapes and volumes, and to a packing station therefor. The method consists in assembling beforehand the objects to be dispatched in a container having a retractable bottom; the container is lowered towards an open-top chest covered with a plasticized film. The bottom of the container is removed so that the objects bear directly upon the plasticized film, whe-reafter vacuum is created in the inner volume of the chest in order to alter the shape of the plasticized film and thus lower the top level of the objects. Then the container is removed in turn and a rigid support is laid upon the objects and bonded to the plasti-cized film at the level of the flange of the aperture; finally, the vacuum is discontinued in the chest for releasing the package thus obtained. This invention is applicable more particularly to the mail order industry and the dispatching of goods in general.

Abstract: ABSTRACT OF THE DISCLOSURE         An optical heterodyne detection pulse receiving system comprises a local oscillator for generating a laser light wave; a half-mirror for aligning the wave fronts of the local laser light wave from the local oscillator and of a modulated light wave, resulting from the modulation of a laser carrier with a pulse signal; a photoelectric converter for receiving the local laser light wave and the modulated light wave, and generating an elec-tric signal having a frequency equal to the difference thereof.          Timing circuitry is provided for extracting the timing signal of the pulse signal from the electric signal and an extractor extracts from the electric signal an intermediate frequency signal equi-valent to the frequency difference between the local oscillator light wave and the laser carrier.  A local oscillator control circuit is provided for comparing the intermediate frequency signal and the timing signal and so controlling the local oscil-lator as to synchronize the Nth multiple (N is a positive integer) of the half cycle of the intermediate frequency with the full cycle of the repeating frequency of the pulse signal.  The inven-tion permits the intermediate frequency to be reduced to less than one third of the value used in prior art systems without causing pulse wave form distortion.
