Abstract: A steam venting extruder feeder is provided for gravity feeding of flowable solid materials into a food extruder downstream of the first normal first zone feed port. The steam venting extruder feeder feeds the material down a tube while simultaneously venting steam from within the extruder around the periphery of the feed tube inside an outer tube in which compressed air is forced to assist in the flow of steam and pulls air in with the feed material preventing steam condensation and build-up in the feed tube.

Abstract: A control circuit for an a.c. to d.c. power converter, in which the load current of the power converter is detected and averaged, and it is added to the voltage control signal of the voltage control system which controls the converter output voltage to be constant, so that the converter control is less affected by the ripple of the load current.

Abstract: A multi-readable information system includes a substrate material and one type of printed information that is readable by a first entity, such as information in machine readable bar code that is printed on an area of the substrate material. A different type of printed information occupies the same field area of the substrate material, such as information in human-readable symbology that is printed in at least a portion of the area occupied by the bar code. The bar code is printed in a first ink that can be read utilizing energy of a first wavelength and the human-readable symbols are printed in a second ink that can be read in a humanly visible wavelength. The humanly visible ink absorbs insufficient energy in the first wavelength to prevent reading of the bar code by a bar code-reading machine and the bar code does not interfere with the readability of the human-readable symbols.

Abstract: An optical inspection machine has a discharge chute provided for receiving fragile articles thrown from a high speed belt in the course of ejecting such articles. The chute has an "S"-shaped bottom with the top of the "S" under the trajectory of the ejected articles, the mid portion of the "S" positioned to receive the falling articles at a minimum impact angle, and the bottom of the "S" discharging the sliding articles after being significantly decelerated due to the variable slope of the "S"-shaped chute bottom. The inspection machine has another "S"-shaped chute for receiving articles from an infeed conveyor and transferring them to the high speed belt while minimizing deceleration.

Abstract: Method and apparatus for controlling the reactivity of lime produced in a lime cycle process that includes the steps of forming burnt lime in a kiln, washing and filtering of lime sludge, and causticizing of green liquor, which lime cycle process steps are carried out under variable operating conditions. At least one mechanical property of the burnt lime is measured, and at least one operating condition of the time cycle process is adjusted, based on the measured mechanical property of the burnt lime, so as to thereby control the reactivity of lime produced in the lime cycle process.

Abstract: The known double facer of the type that when a single-faced cardboard sheet and a liner are being pinched and conveyed by a belt on the upper side and a heating box on the lower side, pressurized air is fed from an air chamber onto the back side of the belt to press the single-faced corrugated cardboard sheet and the liner onto the side of the heating box and thereby the single-faced corrugated cardboard sheet and the liner are made to stick to each other, is improved in that the side walls of the air chamber are supported in a movable manner in the widthwise direction of the sheet so that the width of the air chamber can be adjusted according to the width of the corrugated cardboard sheet to be produced to avoid the side edge portions of the corrugated cardboard sheet from crushing and insufficiently sticking. This results in reduction of unacceptable sheet products and economy of a driving power expense.

Abstract: Cryogenic apparatus and methods are disclosed which enable a substance to be frozen at a rapid rate thereby promoting the formation of a multitude of small ice crystals in the substance rather than a smaller number of large ice crystals. The method comprises circulating a cryogen around a closed canal. The canal is preferably partly immersed in a bath containing a liquid which boils at a temperature below the boiling point of the cryogen in the canal, and which preferably boils at a temperature below the freezing point of the cryogen in the canal. Means for sensing the temperature of the cryogen are provided, the temperature sensing means controlling a heater which maintains the temperature of the cryogen above its freezing point. The cryogen can circulate in a horizontal plane or in a vertical plane. Where the substance to be frozen comprises organic tissue, the cryogen preferably flows in a vertically arranged canal and the tissue is plunged countercurrent into upwardly flowing cryogen.

Thereby performance of the digital protective relay can be significantly improved.

Abstract: In an induction motor controller, for the amount equivalent to the secondary interlinkage flux computed by use of a component of lag of first order based on the search coil voltage or the primary voltage of the induction motor, an error with respect to the actual secondary interlinkage flux is increased in a low-speed range. However, since an estimated amount equivalent to the secondary interlinkage flux computed based on the estimated amount of the secondary interlinkage flux is also attended with the same error with respect to the secondary interlinkage flux, when the former is substracted from the latter, there only remains a term concerning the speed estimation error, which enables an estimation of the speed to be conducted also in the low-speed range.
