Title: Peroxide bleaching process for cellulosic and lignocellulosic material
Inventor: SHACKFORD LEWIS D
IPC: D21C9/153
Filed: 1995-06-29
Abstract: A method for bleaching cellulosic and lignocellulosic pulp using hydrogen peroxide as a bleaching reagent, utilizes a two-step reaction, viz. a short high temperature step at a pressure sufficient to suppress boiling and a longer atmospheric pressure reduced temperature step to consume a substantial portion of the hydrogen peroxide remaining after the short phase. The method includes the steps of introducing pulp (15), at a consistency of 10 %-18 %, to a mixer (100) in which the pulp is heated to a temperature above 100 ~C; adding sufficient sodium hydroxide to bring the pulp to a pH of 8.5; adding sufficient hydrogen peroxide (36) to equal from about 0.5 %-5.0 %, by weight, of the pulp; passing the pulp through a pressurized reactor column (400) at a rate providing a reaction time in the column of between 1 and 30 minutes; and depositing the pulp in a reaction tower and allowing the reaction to proceed for 1-5 hours until a substantial portion of the residual hydrogen peroxide has been consumed. It may be desirable to introduce the pulp to a mixer and add alkali to reactivate residual hydrogen peroxide by bringing the pulp to a pH of at least 9 between bleaching steps.

Title: Power manager system for highway signage
Inventor: HART STEPHEN P
IPC: G09G3/06
Filed: 1997-01-27
Abstract: A power management system for the control and operation of distributed power has a controller operatively connected to a plurality of monitors, switches, control devices, and a visible light emitting array. The monitors, switches, and control devices provide the means for the controller to modulate the power to the visible light emitting array using a current modulator. The current modulator produces a variable power duty cycle that is received by the visible light emitting array. The visible light emitters of that array have a selected perceivable brightness. That brightness is held constant but power is conserved due to the controller modulating the power.

Title: Methods and systems for displaying interlaced video on non-interlaced monitors
Inventor: GLENNON STEPHEN G
IPC: H04N7/01
Filed: 1997-02-12
Abstract: A number of methods to display interlaced video on non-interlaced monitor are disclosed. One method is to display all of the incoming fields but one at a time, and correcting for the positional offset of one field relative to another in theinterlaced data. An important aspect of the present invention is the correction of the positional offset of the two interlaced video fields. There are two ways presented to deal with the vertical offset of the two fields in accordance with the present invention. The first way is that the two fields can be displayed at different positions on the display using a non-interlaced display. The second way is that the video data can be altered to correct the positional offset between the fields. Another method of the present invention is to lock the frame rate of the output video to the incoming field rate or a multiple of the incoming field rate, or tocertain sub-multiples of the incoming field rate. An important feature of this method is that each frame of the output monitor need not match the incoming field time precisely. As long as each output frame is displayed exactly the predetermined number of times, the appearance of smooth motion will be maintained.

Title: Compositions for the detection of proteases in biological samples and methods of use thereof
Inventor: PACKARD BEVERLY S
IPC: C07K7/06
Filed: 1995-10-27
Abstract: The present invention provides for novel reagents whose fluorescence in-creases in the presence of specific proteases. The reagents comprise a characteris-tically folded peptide backbone each end of which is conjugated to a fluorophore.  When the folded peptide is cleaved, as by digestion with a protease, the fluo-rophores provide a high intensity fluorescent signal at a visible wavelength. These protease indicators are particularly well suited for detection of protease activity in biological samples, in particular in frozen tissue sections, because of their high fluorescence signal in the visible wavelengths. Figure 1 shows an HPLC  analysis of the D-NorFES-A protease indicator comprising 5'-carboxytetramethylrhodamine (C2211) as a donor fluorophore and rhodamine X acetamide (R492) as an acceptor fluorophore so that Figure 1 (A) illustrates HPLC of the intact indicator molecule before the addition of elastase; Figure 1 (B) illustrates HPLC where both fluo-rophores absorb after the addition of elastase and Figure 1(C) illustrates HPLC  after the addition of elastase where rhodamine X acetamide (R492) absorbs max-imally. This invention also provides for methods of detecting protease activity in situ in frozen sections.

Title: Automatic frequency control circuit
Inventor: ASAHARA TAKASHI
IPC: H04L27/22
Filed: 1997-05-27
Abstract: A signal from a differential detecting section is decoded by a data decision section and is inputted into a detection area judging section.  In the detection area judging section, synchronous word patterns such as a unique word periodically inserted into the decoded data is detected, determination is made as to in which area the synchronous word pattern was detected,  and in a case where it is judged by the capture determining section that frequency control is executed at an incorrect phase control point, a frequency deviation control section  computes a control rate for a frequency deviation so that a detection area for the received signal will enter an area of a correct phase control point according to a detection area of the received signal, and the frequency deviation is corrected so that control is executed at the correct phase control point by adding a value corresponding to the control rate to an output value from the averaging filter section.

Title: Meat fat removal enhancement
Inventor: MILKOWSKI ANDREW L
IPC: A23L13/00
Filed: 1997-07-15
Abstract: Sources of meat having a high fat content, such as pork trimmings, are processed in a manner by which meat products prepared therefrom have a dramatically reduced fat content while retaining the desirable functionality of the unprocessed meat sources.  The fat-containing meat trimmings or the like are comminuted, phosphated, heated and centrifuged under specific processing conditions in order to provide unformulated raw low-fat or no-fat meat having a fat content of not greater than on the order of about 1.5 percent by weight while having excellent functionality.  The unformulated reduced fat meat is formable into a variety of familiar meat products, including wieners, sausages, hamburger patties, and the like, thereby providing products having taste, appearance, texture and other qualities which are substantially indistinguishable from products prepared from higher fat unformulated raw materials but which have very low fat contents.  The phosphate use accounts for a fat reduction of from about 10% to about 40%.
