Abstract: HERBICIDE COMPOSITIONS OF EXTENDED SOIL SOIL LIFE               Abstract of the Disclosure Herbicidally active thiolcarbamates are employed in combination with certain allyl amine salts of thiocarbamic acid oompounds having the formula   wherein R4 and R5 are independently selected from the group consisting of allyl, alkyl substituted allyl, and lower alkyl groups having from about 1 to about 6 carbon atoms;       R6 and R7 are independently selected from the group consisting of allyl, alkyl substituted allyl, and lower alkyl groups having from about 1 to about 6 carbon atoms; and X is oxygen or sulfur wherein at least one of R4 and R5 and at least one of R6 and R7 is an allyl group.  In a typical application, the allyl amine salt of thiocarbamic acid compound is included in sufficient quantity to lessen the rate of soil degradation of the thiolcarbamate. As a result, the herbicidal effectiveness of the thiolcarbamate is enhanced and prolonged, rendering single application of the herbicide effective over a longer period of time.

Abstract: Abstract:    A heat pump system for a building provides space heating or cooling, together with a supply of hot water available in both the heating and cooling seasons or when the building space is neither heated nor cooled.  The system is also versatile in that it can be readily accommodated to new construction (forced air systems) or to the retrofitting of existing buildings, the majority of which are fitted with convection type hot water radiators.  These results are achieved by a refrigerant circuit that includes three heat exchangers (12, 15, 16), one (12) linked to a heat source (10), one (15) to a forced air system including a blower (17) and the third (16) to a hot water circuit (40-49) that supplies heat to the radiators (47) and to a hot water tank (41).  A reversing valve (13) in the refrigerant circuit and a two way valve (42) in the hot water circuit enable selection of one of several operating modes, i.e. space heating only, space cooling only, hot water heating only, or one or more combinations of these requirements.  The valve (42) in the hot water system can give priority to the hot water tank (41) over the radiators (47).

Abstract: ABSTRACT OF THE DISCLOSURE           A seat plate for protecting wooden structural members against structural damage due to crushing, as well as the effects of moisture, humidity and the like.  The plate member includes a pair of mutually perpendicular planar members and, in one embodiment, is in the form of a flat sheet metal plate which is bent along a fold line to provide first and second planar plate portions intersecting each other at right angles.  One of the plate portions has a dimension in a direction perpendicular to the fold line which is substantially greater than the dimension of the other plate portion in a direction perpendicular to the fold line.  The smaller of the two plate portions has a plurality of teeth struck therein to provide a means of attaching the seat plate member to the wooden structural member.  In use, the seat plate may be installed with the smaller plate portion contiguous with a vertical side wall of the structural member, and with the larger plate portion contiguous with a lower horizontal surface of the structural member.

Abstract: IMPROVED PUNCTURE-RESISTANT CONTAINER     ABSTRACT OF THE INVENTION           The invention is directed to an improved open-ended flexible plastic container which  is  adapted  to package a meat article having protruding bone  sections.   In  particular,  the  container comprises  a flexible bag preferrably formed from an oriented, i.e. heat shrinkable, and  heat  sealable  plastic  material.   Since  the  bag  material  is susceptible to puncture by bone sections which may protrude from a meat article, one face of at least one side of the bag is provided with a sheet of material which is more resistant to bone puncture than the bag material.  The sheet may be adhered on an interior or exterior face of the side of the bag, as desired.  The puncture resistant sheet is located on and adhered to the bag in such a manner that it can be aligned with and overlie the protruding bone sections upon insertion of the meat article  into  the  bag.   Preferably  the  sheet  of  puncture  resistant material is smaller in size than the face of the side of the bag to which the  sheet is adhered.   Additionally,  the puncture resistant sheet is provided with at least one line of weakness which allows the puncture resistant sheet to maintain its original alignment with the protruding bone  sections  of the meat article during a vacuum packaging process.

Abstract: PROCESS FOR PRODUCING CARBONATED BEVERAGES AND PACKAGE THEREFOR A method is disclosed of producing a carbonated beverage for example a soft drink, which method comprises dispensing into a sealable receptacle a predetermined amount of a liquid flavour extract, adding to said receptacle an appropriate portion of yeast, fermentable sugar and an amount of water to provide suitable dilution of said flavour extract, and permitting the receptacle to stand so as to effect fermentation by the yeast and consequently production of a carbonated soft drink. Control reagents are incorporated in the liquid flavour extract to provide a suitable "bite" in the eventual beverage and to cause termination of fermentation when the pH drops to a certain level. The method affords a simple means of producing soft drink beverages in small or large quantities in the home. Also disclosed is a unitary package comprising the liquid flavour extract, individual portions of the yeast and dispensing means for releasing a predetermined portion of the extract into a sealable receptacle for commencing the fermentation procedure.
