Title: Poultry defeathering apparatus
Inventor: HATHORN JACK LAVOID
IPC: A22C21/02
Filed: 1970-04-01
Abstract: 1,262,601. Poultry plucking machines. GORDON JOHNSON CO. 1 April, 1970, No. 15402/70. Heading A2U.  A poultry plucking machine comprises a pair of vertical plates 80, 84 which are driven in orbital paths in their own planes by crankshafts 76, each formed integrally with a driving shaft 74, a number, preferably four, of these crankshafts being provided to support each plate, and resilient plucking fingers 86 which are secured to each plate so that the fingers project towards a central vertical plane between the plates, the poultry being conveyed along this plane by an overhead chain which is attached at intervals to brackets 6 having rollers 8 running on a track rail 4. Preferably, as shown, the plates, their driving shafts, and respective driving motors 102, are mounted on separate frames 34 which are adjustable towards and away from each other, by being supported through rollers 46 on rails 26 (28) and having nut members of opposite hand mounted in the respective frames engaging corresponding threaded portions on shafts 50 which are disposed adjacent opposite ends of the frames 34 and carry handwheels 52. The direction of the orbital movements of the plates is the same and is such that when the plates are moving towards the poultry entering between them they are also moving downwardly. Additional resilient fingers 90 secured to inwardly bent portions 88 of the plates 80, 84 prevent the poultry rising upwardly out from between the plates during travel from one end to the other. The fingers 86 on the two plates are arranged to approach each other sufficiently closely to ensure that they exert a substantially continuous rubbing action on the poultry. By this means, wear on the fingers is said to be reduced and at the same time made more even, while a reduced fingertip speed of 10,000 inches per minute as compared with the 30,000 inches per minute of a typical drum or disc type plucking machine is said to result in a superior plucking efficiency as compared to the drum or disc type plucking machine. In order to balance the masses of the plates 80, 84 and the fingers 86, 90, counterweights 78 are provided on the shafts 74.

Abstract: 1,268,566. Spectrophotometers. POLSKA AKADEMIA NAVK, INSTITUT CHEMII FIZYCZNEJ. March 25, 1969 [March 28, 1968], No.15642/69. Heading G2J. A spectrophotometer, having a mono-chromator system comprising a light source in the form of a luminous spot moving on a luminescent screen of a cathode ray tube, consists of a grating monochromator and a prismatic or filter monochromator, the entrance slit or slits of the prismatic or filter mono-chromator coinciding with the exit slit or slits of the grating monochromator, and the luminous spot being movable along one of several paths situated side-by-side, whereby through the exit slit of the prismatic or filter mono-chromator is transmitted a spectrum of an order of diffraction depending on the path of movement of the luminous spot. In one embodiment the luminous spot scans a plurality of paths 2, 3, 4, the light output being collimated by a concave mirror 5 on to a diffraction grating 6 from which it is reflected via mirror 5 to focus on an exit slit 7. The light from slit 7 passes on to a further concave mirror 11 which reflects the beam on to a prism 12 having a reflective backing. The mirror 11 reflects light from prism 12 and focuses it on a final exit slit 13. The paths 2, 3, 4, grating 6, slit 7, prism 12 and slit 13 all lie in one plane which is the focal plane of both mirrors 5 and 11. Thus it is an image of grating 6 which is focused on prism 12. For each path 2, 3, 4 the grating 6, prism 12 and slit 13 will pass light of a different wavelength, the slit 13 being so located as to blank off undesired harmonics. Path 2, 3, 4 is selected by a change in voltage at the tube. In an alternative embodiment the prismatic mono-chromator is replaced by a filter mono-chromator. This filter monochromator may comprise a plurality of optical filters disposed adjacent the exit slit of the monochromator, each filter covering a different segment of the slit and transmitting light of a different wavelength, light passing through the filters depending on the path of movement of the luminous spot. In a further alternative the grating monochromator may have several exit slits in front of each of which is disposed an optical filter.
