Title: Apparatus for forming a product of filler material encased in an envelope of covering material
Inventor: HAYASHI TORAHIKO
IPC: A23P30/25
Filed: 1968-04-11
Abstract: 1,218,256. Extruding coated materials. T. HAYASHI. 11 April, 1968 [13 April, 1967], No. 17598/68. Heading B5A. Apparatus for forming a product of a filler material encased in an envelope of a covering material comprises means for extruding a sleeve of covering material around a core of filler material and means for continually severing portions of the extrudate so that each portion comprises a core of filler material completely surrounded by covering material. The apparatus is intended for use in enveloping a food product in an outer casing of, for example, dough or batter. As shown, filler material 25 is fed from a hopper 1 down the central passage of rotating extruder screw 3. The covering material 26 is fed by feeding device 10 to cylinder 6, down which it is forced by extruder screw 4 to form a sheath surrounding the filler material 25. The thickness of the covering material is determined by a ring 5 housed at the base of the cylinder 6. The cutting device comprises a pair of rotary cutters 12 each comprising a "cup-shaped" body having a spiral blade of varying radius and 1¢ turns or less, the edge of the blade being rounded and the underside of the blade being rectilinear and varying from vertical in its highest position to horizontal in its lowest. The blades rotate in opposite directions with the same angular speed. A dish 18 is situated below and between the blades and is adapted for rotational and up-and-down movement. The shape of the cutter blades (which is precisely specified) is such that as the extruded material passes between the cutter blades, the filter material stream is broken and the covering layer is closed around it. The finished product is pushed off to dish 18 by a blade 23 mounted on one of the cutters and is removed by a conveyer 24.

Abstract: 756,560. Television pick-up tubes. FERNSEH, GES. July 3, 1953 [July 5, 1952], No. 18524/53. Class 39 (1). A storage target is scanned by a beam of highvelocity electrons and is flooded with a stream of low-velocity electrons derived from an auxiliary photo-cathode disposed on a surface facing the target, and two or more auxiliary electrodes maintained at positive potentials relative to the photo-cathode, surround the path of the slow electrons from photo-cathode to target with the electrode having the highest potential nearest the target. Part-annular auxiliary photo-cathode 1 is formed on the wall of the tube between the image converter section containing main photo-cathode 6 and the storage section containing target 2 and may be deposited at the same time as 6 by evaporation of antimony and caesium. Between 1 and 2 glass cylinder 4 is fused to the envelope and metallic coating 8 is condensed on to the inner surface of 4 so that this section constitutes one auxiliary electrode and is maintained between 1 and 2 volts positive relative to photo cathode 1. The target consists of an insulating and secondary-electron-emissive layer 2 deposited on signal output plate 7. The second auxiliary electrode is a rectangular frame 3 consisting of four separate wires, whose positive potentials can be separately controlled at values higher than that of electrode 8, mounted on the scanned side of the target, each wire being carried by a support 10 (Fig. 2) which projects through an aperture in plate 7. Image converter anode 5 is deposited by condensation on glass cylinder 9 supported from the tube wall by contact at a few points to provide good insulation. Disturbances due to fluctuating illumination such as from fluorescent lamps can be counteracted as follows. Stray electrons collected by one wire of frame 3 which is connected via a high resistance to a potential of 6 to 10 volts positive, produce a signal which is fed through a low-pass filter to the input of the picture amplifier in antiphase to the image signal from target 7. Auxiliary photo-cathode 1 is preferably illuminated by glow-discharge lamps operated from a stabilized D.C. supply.
