Title: Apparatus for extruding spherically-shaped food products
IPC: A21C11/16
Filed: 1973-12-13
Abstract: 1418699 Extruding food spheres CAMPBELL SOUP CO 13 Dec 1973 57844/73 Heading B5A Spherical shaped food products, e.g. dumplings or meatballs, are formed by intermittent extrusion from a plurality of circularr orifices 20a in an upper die plate 20, as it and a lower contacting die plate 21 are linearly reciprocated in opposite directions to intermittently bring the orifices 20a into and out of alignment with orifices 21a in the lower die plate. In the Figs. 2 and 5 embodiment, each plate is reciprocated from a crank, e.g. 32, acting through links and a lever, e.g. 38, 40, and 34. The orifices 21a are oblate, and their semi-circular edges are tapered downwardly to effect a cutting action on the meatballs extruding from the orifices 20a. Each orifice 20a moves into central alignment with one of an adjacent pair of orifices 21a at each limit of the reciprocating movement of the plates, corresponding substantially to a dwell period, as shown in Fig. 2, and the shearing of the meatball is effected over the period of the relative reciprocation which is effected at maximum velocity, as shown in Fig. 5. The orifices 20a and 21a are spaced so that each orifice 20a is simultaneously in partial alignment with an adjacent pair of orifices 21a, to avoid extrusion pressure fluctuations. In the Fig. 11 embodiment both apertures 120a and 121a are cylindrical and of the same size and spacing, and the apertures are only in alignment at one of the extremities of reciprocation of the plates 120, 121, with each aperture 120a moving into and out of alignment with only one aperture 121a. The reciprocation of the plates 120, 121 is effected by a similar lever connection, but from a cam groove providing a dwell period of 200 degrees with the apertures 120a, 121a, in alignment, and a closing period of 100 degrees comprising 60 degrees of low, and 40 degrees of high acceleration to minimize extrusion pressure fluctuations. The extrusion is effected by a pump, and the spherical extrusions fall from the die on to a conveyer belt.

Abstract: 1,255,968. Granulating. GLAVERBEL. Dec.24, 1968 [Jan. 4, 1968], No.61437/68.  Heading C7X. [Also in Division C1] A liquid or pasty material, e.g. molten glass, slag or scoria is formed into particles by feeding it through the central shaft 22 to a rotating disc 20. The particles flung from the disc by centrifugal force are subjected during their trajectory to the action of one or more transverse jets of gas (which may be heated) either whilst traversing the chamber 24 or after they have passed out of the chamber via the peripheral opening 32. In the embodiment shown, hot gas is fed into the chamber via the pipe 34 to maintain a sufficiently high temperature (other means, e.g. radiant heaters may be used) and a stream of cold air 48 from pipe 42 carries away hot gas from the region outside the chamber. Further outside the chamber, the particles are subjected to an ascending current of air 56 from conduit 58 which increases the length of the trajectory path 54, and to decelerating jets from conduits 59. Further gas currents 78 and 80 serve to deflect the particles into the collecting chamber 40. Within and just outside the chamber 24 are additional gas conduits 106, 108, 112, 114, 120, 122, 124, 126, 66, 92, 94 and 98 from which jets of gas 108, 110, 114, 116, 118, 128, 130, 132, 134, 64, 96, 90 and 100 may issue. Adjustment of the gas velocities of these jets may be employed to vary the nature of the particles produced.
Patent GB-627336-A (GB)
IPC: G03B39/04
Abstract: 627,336. Photographic cameras. KODAK, Ltd. Feb. 28, 1947, No. 5856. Convention date, March 1, 1946. [Class 98 (i)] In a camera in which an image is recorded on a strip of film wrapped round a rotating drum, the objective is mounted on a pivoted carrier with the optical axis inclined to the pivotal axis, the carrier being rotated during exposure to move the objective across the drum, the inclination of the objective axis to the pivotal axis being such that the optical axis remains directed at an object to be photographed located on the pivotal axis. One form is shown in Fig. 2 for recording, for example, the trace on the screen 18 of the cathode-ray tube 17 of an oscillograph 16. The film is carried on a drum 12 in a light-tight casing 11 at the front of which is a gear-wheel 20, with a light-trap, carrying the objective 38 eccentrically mounted. The gear 20 is driven from another, 22, on a shaft which also carries a single tooth ratchet 26, and to which torque is applied through a slipping clutch 36 from a continuously-running motor. The pawl of the ratchet 26 may be released by a lever 34 to allow the shaft carrying the pawl to make one complete turn and traverse the lens 38 across the periphery of the film drum. The drum is driven by a hydraulic motor from a pump unit indicated at C. A speed indicator 118 is connected to a generator driven off the drum shaft. The film-feeding arrangements are shown in Fig. 3. By rotating the drum by an external handwheel 52 (Fig. 2), an access door on the drum is brought into line with a door on the casing. Into the drum are inserted feed and take-up spools 62, 59, between which the film is wound round the drum over rollers 61. To wind the film the drum is turned through 180 degrees until the take-up spool spindle 58 is in line with a shaft 63. The latter can be pushed in to engage couplings on the two shafts to rotate the take-up spool and a footage indicator 73. Ratchets prevent reverse rotation of the spool. When enough film has been wound a handle 81 on a shaft 79 can be turned to operate an eccentric 77 to lower a pawl 75 to engage a ratchet 74 on the feedspool. A small further rotation of the take-up spool then tightens the film round the drum. A member 87 locks, when in inoperative position, the various members which engage the rotating drum. The member 87 operates a micro-switch M<SP>1</SP>. This switch, and others connected to other interlocking devices not specifically described, control indicator lamps 107 (Fig. 2). They may also be electrically interlocked with the control buttons 108 for the pump unit C. The switch 106 controls the motor which drives the lens mount mechanism, and the switch 104 controls the motor 91 of a timing mechanism. The motor drives a disc 90 with a series of apertures in its periphery. Two lamps are arranged to shine through the apertures on to the two inargins respectively of the film. A contact device carried by the gear 20 illuminates the lamps for a period equal to one revolution of the drum to produce a sequence of timing marks in each margin.
