  • Patent number: 5992345
    Abstract: A process and a device for producing sausage casings which bear a coating of spice particles on the inside are distinguished in that the inside of the sausage casing is provided with an adhesive coating which hardens from the liquid state and the spice particles are projected against the adhesive coating while it remains adhesive. The production of the spice particle coating can be interrupted in sections, that is to say in the sections predetermined for tying off individual sausage casings.

  • Patent number: 5796485
    Abstract: An apparatus and a method are presented in order to carry out an automatic optical inspection of an off-center rotating component to be measured. Using a measurement procedure which avoids mechanical contact having a source producing parallel rays and a detecting means, the off-center rotating component is rotated about a rotational axis, whereby a motion of the detecting means is synchronized with the rotation and is carried out in such a fashion that the separation, in the direction of an optical axis, between the off-center rotating component and the detecting means remains constant. In this manner optical distortions are avoided which would otherwise occur in the optical measurement procedure.

  • Patent number: 5331174
    Abstract: To automatically examine medical ampuls to determine their dimensional accuracy, the ampuls are moved in a horizontal position on a chain conveyor in a cadenced manner through an optoelectronic testing station. At the testing station, each ampul is lifted out of the chain conveyor and illuminated by light from a diffusely radiating illumination source perpendicularly to the longitudinal axis of the ampul. In the case of one-point-cut ampuls, the ampuls are rotated about their longitudinal axes during the testing process. The light passing through the ampul is received by a photodiode camera system which converts the images into electrical image signals. These image signals are evaluated with respect to their changes in intensity produced by the tested ampul in order to generate measurement values for the desired ampul dimensions and, if applicable, for their deviations from standard ampul dimensions.
