Abstract: There is disclosed a granular copper hydroxide dry flowable bactericide/fungicide having improved biological activity and a method for making and using same. A bactericide/fungicide is made by forming a homogeneous aqueous slurry containing between approximately 5% and 20% by weight (based on the total weight of all dry ingredients) of a first dispersant selected from the group consisting of partially neutralized polyacrylic acid having a pH of between approximately 5 and 10 and an average molecular weight of between approximately 1,000 and 10,000 and lignin sulfonate, between approximately 0% and 5% by weight (based on the total weight of all dry ingredients) of a second dispersant for bentonite clay, between approximately 40% and 80% by weight (based on the total weight of all dry ingredients) phosphate stabilized cupric hydroxide and between approximately 6% and 30% by weight (based on the total weight of all dry ingredients) bentonite clay; and spray drying the slurry to thereby form a dry free flowing granular bactericide/fungicide product. The slurry can also include antifoam and wetting agents. Other partially neutralized polycarboxylic acid polymers useful as the first dispersant are also disclosed.

Abstract: (1) COOLING OF HYGROSCOPIC PLASTIC COMPOUND STRANDS AFTER                      EXTRUSION :            ABSTRACT:          This system is ideal for hygroscopic brittle materials when extruded in combination of additives with variable moisture content. It has been found that sudden cooling of the strands made the extruded material brittle and thus it becomes impossible to bring them to the puller of the pelletizer to be further processed. Therefore, steady cooling is three steps made the process work for polystyrene crystal. in combination of medium or high impact styrene along with additives.

Abstract: A data display display pager capable of automatically protecting a particular message over a limited period of time.  The receiver stores a message signal in a message signal storage area included in control means thereof.       When the pager detects out of the stored message signal protection information which is made up of a protection time signal indicative of a period of time for protecting the signal and a set of particular marks occurring before and after the protection time signal, it protects the message signal over the protection time.  The message signal is protected in either of two modes which are discriminated from each other on the basis of the number or the kind of particular marks.  During the protection time, the stored message (signal) is displayed in a first mode wherein a message without the protection information appears or in a second mode wherein the entire message appears, depending on the above-mentioned protection mode.          On the elapse of the protection time, the stored message signal has, in a first protection mode, the protection information thereof deleted or has, in a second protection mode, only the particular marks thereof deleted.

Abstract: APPARATUS AND METHOD FOR HANGING FISHING NETS            ABSTRACT OF THE DISCLOSURE           A net web is supported by upper and lower float and  weight  lines  by  a  connecting  structure  which  is connected to the respective line to resist movement along the line. Each connecting structure has an outer portion with a locking opening therein and cooperates with a cord loop.    An  inner  loop  end  portion  of  the  cord  loop cooperates with the line and the connecting structure to resist movement along the line. An outer loop end portion passes  through  the  selvage  of  the  fish  net  web  and cooperates with an adjacent connecting structure and its associated loop. The cord loop of one connecting structure passes  through  the  locking  opening  in  an  adjacent connecting structure, and a cord loop of the said adjacent connecting structure passes through the cord loop of the said  one  structure  to  interfere  therewith  to  prevent separation of the cord loop of the said one structure from the  adjacent  connecting  structure.  This  essentially prevents unintentional unravelling of the cord loops from adjacent connecting means should one cord loop be severed. The structure permits easy connection and disconnection of a fish net web from cooperating float and weight lines, thus significantly reducing skill and labour costs for hanging and repairing nets.

Abstract: Attache cases and business cases in general typically have a portfolio section for organizing papers and a main packing section.          Depending on  the  needs  of  the  user,  these  portions  can  be selectively closed off.  However, it's best that these sections are relatively accessible depending on whether the case is opened from the vertical position or whether the case is opened from the horizontal  position.    Accordingly,  Applicant  has  provided  a portfolio catch system which, depending on the orientation of the case, holds the portfolio in a closed position where the front of the portfolio is attached to the lid portion of the case, or in the alternative, if the case is opened from the vertical position, the panel is held to the base of the case, thus preventing the contents of the base from spilling and automatically permitting ready access to the contents of the portfolio.  Also disclosed is a series of lid containers and base containers arrayed along the upper edge of the lid and base shells at the upper side of the case.   These containers are readily accessible in all conditions of the case, and are especially accessible when the case is opened from the vertical position wherein access to the contents of the portfolio, as well as these lid and base containers, can be readily had.

Abstract: The present invention relates to the identification and purification of a herpes protease and a nucleic acid segment coding for two proteins. The first protein is the herpes protease which is able to cleave itself and also cleave the second protein. This protease is required for the assembly of the herpes virus capsid, therefore is essential for replication. The second protein has previously been designated as the family of. proteins in viral infected cells, ICP35. The protease and its substrates are encoded by overlapping nucleic acid segments. This invention also relates to a promoter sequence for the second protein. Methods are presented of producing a viral protease, screening a protease inhibitor which may be used in a drug designed for the treatment of herpes disease, methods for treating herpes and other viral infections wherein the virus employs a protease substantially similar to the herpes protease, for capsid production. Methods for detecting herpes infections and other viral infections are also disclosed.
