Abstract: Poultry carcasses are treated to improve the eating qualities, notably flavor, tenderness, juiciness, etc. by injecting an additive such as a liquid into the meat tissue of the leg and thigh portions by inserting a hollow needle through both of the portions from either the end of the leg from which the foot has been severed, or from the posterior opening in the carcass, and without penetrating the skin of the carcass. The needle is inserted into an empty sheath of a tendon which has been pulled from the leg portion, and the needle is advanced through the sheath and beneath the poultry skin through the flesh of the leg without penetrating the skin of the thigh and leg and the additive is then introduced into the flesh.

Abstract: A method of hulling berries in which the unhulled berries are supported on a pair of oppositely rotating brushes with their adjacent sides moving downwardly and with the bristles in partially lapping relation at their adjacent sides.The bristles are sufficiently stiff and resilient to pull sepals drawn between them downwardly from a berry supported on the pair of brushes, without tearing them, and to partially enter each berry at the stem end of the calyx (hull) for passing over the enlargement on the calyx at said end to quickly push the enlargement, with the sepals attached, out of the berry.In operation, upon one of the sepals of a berry supported on the pair of brushes being engaged between bristles, the berry will be held against movement longitudinally of the brushes while the remaining sepals are progressively gathered between the brushes, and after being gathered the brushes slightly enter the berry to move across said enlargement and remove it, including the gathered sepals, from the berry.

Abstract: To achieve constant brightness from the chlorine stage of a wood pulp bleaching system, the chlorine addition rate is controlled by two white light photosensors positioned, respectively, 1-5 minutes downstream of the chlorine addition point and immediately prior to the chlorine washers. A relative error signal from the late photosensor is cascaded upon the set-point of a signal differentiator for the early photosensor to generate a chlorine valve control signal. The photosensors comprise selenium photocells positioned against a transparent stock conduit window and reflection illuminated by a low power white light source positioned more remotely from the window than the photocell at a discreet offset angle relative thereto. The white light is directed past the photocells, through the windows and into the flow stream; the photocells being responsive to the relative magnitude of white light reflected from the wood pulp. The power generated from the photocell is correlated to the pulp brightness.

Abstract: A process for producing uniformly shaped chip-type products having a surface design thereon. The process provides chip-type products having a series of substantially parallel alternate arcuate ridges and grooves extending across both surfaces which effect a rippled appearance to the products wherein the rippled configuration is impressed only on one surface of the dough by a mill roll having an annularly grooved surface.
