Abstract: For the production of hetero-bispecific monoclonal antibodies at least the genes for the light chain and for the variable part of the heavy chain are isolated from a hybridoma cell line which secretes an antibody with a desired specificity and they are inserted into a eukaryotic plasmid vector which contains a marker capable of selection together with a strong promoter, this expression vector is transfected into a hybridoma cell line which secretes antibodies with a second desired specificity, the cell line is cultured, the antibodies are obtained and the bispecific antibody is isolated.

Abstract: The food and beverage preservative of this invention uses a finely divided calcium component in a solution of vinegar, alcohol and a fermented germ. The calcium component is present in said preservative in an amount of from 3,000 to 4,000 mg for each 100 to 200 cc of the solution. The preservative has a ph of from 4.5 to 5.5. The calcium component is derived from egg shells, clam shells, oyster shells, scallop shells, animal bones, fish bones, coral and any mixtures of two or more of these.

Abstract: A continuous process of producing beer is described. Starch-containing raw materials are disintegrated and are optionally processed to form malt, a wort is produced from the disintegrated and optionally malted raw materials, and the wort is subjected to alcoholic fermentation. In that process all process steps are performed continuously. The mash is initially heated in a reactor system to a temperature of 75.degree. to 85.degree. C. The grain residue is removed from the mash. The wort is subsequently hopped and is heated to a temperature from 105.degree. to 140.degree. C. This is succeeded by a flash evaporation, a removal of the dregs and a cooling of the wort, which is subsequently fermented at 6.degree. to 25.degree. in the presence of a biocatalyst. The fermenting process may be succeeded by a partial or full continuous de-alcoholization of the beer.

Abstract: A water-dispersible lipidic hop extract composition, comprising at least 10% by weight of free fatty acid substances derived from hops, is useful to increase the utilization of the hop aroma and flavor components. It may be produced by treatment of an extract of hops with an excess of alkali. The starting hop extract, made conventionally as by extraction with organic solvent or carbon dioxide, preferably has alpha, isoalpha, and beta hop acids removed before treatment with excess alkali. A cosolvent, such as a lower alkanol, polyol, or wetting agent, heat, or high shear may be used to improve mixing of the lipidic organic phase of the hop extract with the excess alkali. The water-dispersible lipidic hop extract imparts an enhanced hop aroma and flavor upon addition to the wort at some point during the brewing process between boiling and the beginning of fermentation. A beer incorporating the dispersible lipidic hop extract has a stronger hop aroma and flavor than beer incorporating the usual hop extract.

Abstract: The invention relates to a method of ensiling fodder made by combining fresh or wilted silage material with solid carbon dioxide while utilizing the essential conditions for homofermentative lactic acid fermentation, which are known in themselves and the basic parameters of which can be monitored. The solid carbon dioxide is added in an amount of 0.5 to 20 kg per ton, preferably 1 to 3 kg per ton, according to a principle of distribution that gives priority to the zones of the silo most endangered by oxygen in the air, in particular the marginal zones. The fermentation process must take place with an amount of silage material large enough to be little affected by the ambient temperature.

Abstract: Wines and other alcoholic beverages are treated to remove sulfides by passing the beverage through a filter medium comprising polyvinyl polypyrrolidone, polyvinylimidazole, or a copolymer of the monomers of these two polymers, the polymer or copolymer having been pretreated with a solution of a metallic salt, preferably copper sulfate or silver nitrate.

A wrap material is tightly secured around the food product unit and the protective band to form a package. The protective band may have alternating narrow segments and wide segments to ensure that the wrap material keeps the top and bottom extremities of the food product unit inside the protective band and spaced from the upper and lower edges of the wide segments of the protective band.

Abstract: A coccidiosis-relieving agent comprising cashew nut shell oil and/or anacardic acids as an active ingredient and a feed for relieving coccidiosis comprising cashew nut shell oil and/or anacardic acids. Cecal lesions of livestock and poultry, in particular poultry such as fowl, can be relieved by adding cashew nut shell oil and/or anacardic acids to a feed. The coccidiosis-relieving agent according to the present invention does not completely inactivate Coccidium protozoa, but induces slight infection to immunize an animal, thus achieving a so-called "passive immunological effect". The coccidiosis-relieving agent is efficacious in allowing Coccidium protozoa to grow and imparting sufficient immunological stimuli while relieving lesions to thereby lessen damage to poultry such as fowls.

Abstract: The invention pertains to a novel cooking utensil for use in cooking food together with a conventional cooking vessel such as a covered skillet. The cooking utensil comprises a thin, substantially planar food-supporting cooking member having a bottom surface shaped substantially identically to a lower, inner surface of the conventional cooking vessel so that the food supporting member will substantially completely cover the lower, inner surface of the cooking vessel in flush contact therewith when the food supporting member is placed in the vessel, and handle means integrally connected to a central portion of an upper surface of the food supporting member for lifting and handling the food supporting member. The food supporting member preferably has a uniform thickness significantly smaller than the thickness of a bottom wall portion of the cooking vessel, and a continuous surface so that fluid cannot pass therethrough during a cooking operation.

Abstract: The present invention is directed to a convenient and economical method for improving the rate of raising newborn piglets from the pregnancy of the sow to the weaning of the piglets. The method reduces the incidence of premature piglets and increases the lacteal yield of breeding sows by feeding the breeding sows a feed containing saccharides mainly composed of oligosaccharides.

Abstract: A method and device in the regulation of the headbox of a paper machine/board machine, in which additional flows are introduced into the pulp suspension at different points across the width of the headbox. The concentration of the additional flows is different than the average concentration of the pulp suspension. The additional flows are introduced through additional-flow pipes to the vicinity of inlet openings of turbulence tubes of a turbulence generator. The grammage profile of the web in the direction of width of the web is regulated in the headbox by adjusting the distance of the end of the additional-flow pipe/pipes from the turbulence generator, whereby the amount of the additional flow entering into the additional-flow pipes and, at the same time, the amount of the pulp suspension flow are regulated.

Abstract: Effluents are minimized from a cellulose pulp mill having a recovery boiler by concentrating liquid effluents from the bleach plant and/or liquid spills from process streams, incinerating the concentrated effluents in the recovery boiler, removing particles present in the flue gases from the recovery boiler to produce an ash including salts containing potassium and chloride, and sulfur compounds, and removing the potassium and chloride from the ash while returning the sulfur containing compounds to the recovery loop, so as to balance the sulfur, chloride and potassium levels in the mill. The sulfur is typically returned directly to a stream of black liquor just before entry into the recovery boiler. Green liquor is produced from the melt, which preferably is treated to remove metals from it prior to caustization (e.g. by sedimentation and/or filtration), and prior to green liquor crystallization to produce sodium hydroxide.
