Title: Process for recycling aqueous fluid absorbents fines to a polymerizer
Inventor: GRAHAM ANDREW T
IPC: C08F265/00
Filed: 1992-05-15
Abstract: ABSTRACT     A process is described for recycling dry aqueous fluid absorbent polymer fines into a process that includes a polymerization step for making the aqueous fluid absorbent polymer.  The process requires recovering the dry polymer fines, mixing the fines with a polymerizable monomer solution for making the aqueous fluid absorbent polymer and polymerizing the mixture of fines and monomer to form the aqueous fluid absorbent polymer.  In the process the fines are incorporated into the new polymer gel and becomes indistinguishable therefrom.  The gel may then comminuted into a particulate dried and then separated into a portion having a desired minimum particle size in a fines portion having less than the desired size.  The fines portion is then recycled up to about 30 percent by weight based on gel solids may be recycled for the 38,9992-F     preferred polyacrylate based aqueous fluid absorbent polymer.     38,992-F

Abstract: The data words in a list are grouped into n groups.          The grouping is performed by selecting the first data word of the list and every nth data word thereafter to form a first group, and then by selecting the next data word of the list and every nth data word thereafter to form a second group and repeating this selection process until n groups are formed.          The maximum/minimum among the data words of each of the n groups is determined, and a data word number of the maximum/minimum is ascertained.  Subsequently, an absolute data word number of the maximum/minimum of each of said n groups is determined using the data word number obtained and the group number and n.  Finally, the absolute data word is determined by ascertaining the maximum/minimum in the list by comparing the n maximums/minimums of the n groups.

Title: Apparatus and method for magnetically confining molten metal
Inventor: GERBER HOWARD L
IPC: B22D27/02
Filed: 1992-06-12
Abstract: Molten metal, in the gap between two counter-rotating rolls of a continuous strip-casting apparatus, is prevented from leaking out of an open side of the gap by a magnetic confining apparatus employing the proximity effect to produce a horizontal magnetic field extending through the open side of the gap.  The apparatus includes structure for confining the magnetic field substantially to the open side of the gap and for preventing dissipation of the magnetic field away from the open side of the gap.

Title: Tape tensioning mechanism with tape loading-activated tensioning pin
Inventor: KUSHIRO SUNAO
IPC: G11B15/665
Filed: 1992-06-22
Abstract: ABSTRACT OF THE DISCLOSURE           A video tape recorder has a tape tensioning mechanism for tensioning a magnetic tape drawn out of a tape cassette.  The tape tensioning mechanism has a ten-sioning arm angularly movably mounted on a movable chassis and having a tensioning pin for contacting the tape to ten-sion the tape when the tape has been loaded in a predeter-mined tape path, a tightening lever movably mounted on the movable chassis, and a tension spring for normally urging the tensioning arm in a direction to turn the tensioning arm to bring the tensioning pin into contact with the tape.          A pusher is fixedly mounted on a fixed chassis for pushing the tightening lever to tighten the tension spring substan-tially at the same time that the magnetic tape is loaded in the predetermined tape path.  When the magnetic tape is not loaded in the tape path, the tightening lever is released from the pusher to loosen the tension spring.  Since the tension spring is not required to bias the tensioning arm when the magnetic tape is unloaded and is only required to bias the tensioning arm when the magnetic tape is loaded, the tension spring may be of a relatively small size.

Abstract: In a color television system having picture-in-picture (PIP) capability, apparatus is provided for automatically modifying the operation of a beam current limiting (BCL) section while the small picture is being displayed to prevent the visibility of the small picture from being adversely affected. In an embodiment, a contrast BCL control signal is decoupled from the contrast section, and a substitute control signal, at least approximating the user responsive contrast control signal, is substituted for it in response to a switching signal which causes the small picture to be inserted within the big gicture. however, the BCL section continues to be responsive to the beam current during the time interval in which the small picture is displayed so that the BCL contrast control signal accurately represents the contents of the entire image. In addition, the operation of an automatic contrast reduction section which is responsive to a peak-white representative video signal is also disabled during the time interval in which the small picture is displayed. In an alternate embodiment only the operation of the contrast BCL section is disabled, but the operation of the automatic contrast control is maintained. If desired, a brightness BCL control signal may also be decoupled from the brightness section.
