Abstract: OXYGEN REACTOR SYSTEMS PULP REJECT TREATMENT     ABSTRACT OF THE DISCLOSURE      A method and apparatus for the delignification of cellulosic fiber material to minimize the amount of reject material in the final pulp produced.  The fiber material is digested, washed, oxygen delignified, and passed through a screening stage to provide a main pulp stream, and a reject stream from the separation stage. The flow and consistency of the separated reject mater-ial is determined, the reject material is refined, and sufficient chemical is added to the separated reject material, based upon the flow and consistency thereof, so that subsequent delignification of the reject mater-ial may be effected.  This may be accomplished either by passing the reject material through a separate oxygen delignification stage and then returning it to the main pulp stream, or adding caustic to it and soaking it in a soak tank for predetermined period of time, and then returning it to the main pulp stream before the oxygen delignification stage therein.

Abstract: ELECTRONIC INJECTION METERING AND MONITORING SYSTEM    William W. Norton Jack L. Stansbeary Johann Clemens Roscoe T. Earl ABSTRACT OF THE DISCLOSURE          A system is provided for injecting slaughtered animal carcasses with tenderizing solution.  The carcasses to be injected are weighed and are conveyed to a plurality of sequential injection stations. A number of injection headers are energized for calculated energization time periods.  Each carcass is injected by each injection header with solution that flows automatically for a calculated time period that is generally proportional to the carcass weight.        A microprocessor is utilized to provide a separate data storage location for each injection station.  Data is provided to each storage location in proper sequence as the side to be injected is conveyed to sequential injection stations.  A separate timing means is provided for each injection station, and data from the storage location is transferred to the timing means in sequence as the carcass to be injected is conveyed to sequential injection stations.        The microprocessor is also utilized to generate a display that is used to monitor the output and internal performance of the injection system with regard to weight data sequential transfer and also injection count number information.  An alarm status condition is generated if the system performance is not in compliance with internal standards.

Abstract: RCA 73,301 ABSTRACT         The outputs of a pair of non-additive combiners are coupled to respective inputs of a differential amplifier and an a.c. signal to be amplified is applied to a selected input of one of the combiners.  A control circuit operates in a first mode to apply control voltages to the combiner inputs for causing the one combiner to block the a.c. signal and also causing both combiners to apply a common mode input voltage of a first value to the amplifier inputs. In a second mode, the control circuit changes the values of the control voltages in a sense to cause the one combiner to pass the a.c. signal and to also cause both combiners to apply a common mode input voltage of a second value to the amplifier inputs whereby, in either mode, the amplifier produces a constant quiescent d.c. output voltage.

Abstract: ABSTRACT OF THE DISCLOSURE:           A method of forming a beam blank, in which a plate-shaped slab is reduction-rolled in the widthwise direction by working rolls having box grooves each formed at the center with a projection, whereby side spreadings are created at opposite end portions in the widthwise direction of the slab to provide a blank of dog-bone shape in cross section.  The blank is further rolled by working rolls having beam blank grooves to provide a beam blank of a predetermined shape in cross section.  The plate-shaped slab is then reduction-rolled in the widthwise direction by working rolls having box grooves each formed at the center with a projection, according to:  a first step in which the plate-shaped slab is reduction-rolled in the widthwise direction box grooves each formed at the center with a projection to provide grooves for positioning in the centers at opposite end faces in the widthwise direction of the plate-shaped slab; a second step in which the plate-shaped slab is further successively reduction-rolled in the widthwise direction by respective box grooves successively larger in width than those used in the preceding step and each formed at the center with a projection fit in the groove; and a third step in which the plate-shaped slab is further reduction-rolled in the widthwise direction by working rolls with flat bottoms or working rolls having box grooves each formed with a projection low in height, whereby recesses formed by use of the projections at opposite end faces in the widthwise direction of the slab are lessened in depth and the side spreadings are further facilitated.

Abstract: NEH:em #3697 COLLAPSIBLE SOLUTION CONTAINER          Abstract of the Disclosure A collapsible container for medical fluids which is blow molded in such a manner that when the con-tainer is supported at one end, the side wall portions will automatically become self pleating and will continue to assume a pleating condition toward the bottom of the container as the medical fluid is emptied therefrom. This self-pleating aspect is accomplished by blow molding the container in such a manner that the shoulder and side wall portions are of an average smaller dimension through-out the longitudinal axis of the body section and the shoulder portions join the side wall portions at an angle so as to effect a structurally weak point when the bag is supported by a hanger tab.  This self-pleating phenomenon results in a container wherein the meniscus of the fluid is readily readable and accurately ascertained.

Abstract: ABSTRACT OF THE DISCLOSURE       Method and apparatus for pressurized fluid stream treatment of the surface of a relatively moving substrate to impart visual surface changes thereto.  The apparatus includes a fluid discharge manifold comprising an elongate compartment with discharge slot disposed across the path of relative movement of the substrate to discharge pressurized heated fluid, such as air, in one or more narrow discrete streams into the surface of a substrate, such as a textile, fabric.  A plurality of spaced, cooler air out-lets are disposed in the discharge slot of the manifold, and pressurized cooler air is select-ively directed through the outlets and across the slot in accordance with pattern information to block the heated air streams from exiting from the discharge slot in selected locations and thus pattern the surface of the web.  Associated with each of a plurality of inlet conduits is a separate heater unit and temperature sensing means, as well as an individual metering valve, for heating and adjusting the flow of pressur-ized fluid passing into the manifold.  The indi-vidual metering valves are adjusted to balance the temperature of the heated fluid exiting from the inlet conduits into the manifold.  A single temperature sensing device, located in the mani-fold, may then be used to adjust a uniform supply of power to all heater units, thereby maintaining a desired fluid temperature in the manifold.      The invention further includes means for supplying a heat transfer fluid to the interior of a rotatable roll employed to support the sub-strate during its passage by the heated fluid distributing manifold.      The heated pressurized streams of air striking the surface of a thermoplastic yarn or fiber containing textile fabric causes thermal modification and longitudinal shrinkage of thermoplastic yarn and fiber components therein to provide the patterned appearance to the fabric surface.      Also specifically disclosed are novel textile pile fabrics having patterned surface effects therein, and thermoplastic textile woven fabrics which are treated with the heated stream or streams to provide a crepe or pucker appear-ance in the fabric.

The engineers keyboard is so mounted that it may be moved to a position in front of the console in substantial alignment with the cathode ray tube and the operators keyboard when it is desired to make changes in the computer data base.  At other times, the engineers keyboard is moved to a retracted position below the work space of the console, under the operators keyboard.
