Abstract: Qualitative and quantitative meat production is improved considerably and decisively through administration of radio-active iodine isotope compounds, preferably the artificial iodine isotope I.sup.131. The glandular thyroid tissue is destroyed to any desirable degree by its administration. This method has the great advantage that in general a single administration suffices to achieve dramatic results. The method does not interfere with other measures used to improve meat production, such as early castration, or the use of feed additives like vitamins, antibiotics, and hormone preparations.

Abstract: Valuable products are obtained from Theobroma fruits by preferably removing the peels from said fruits, opening the fruits, separating the seeds from the preferably peeled parenchymatous part of the fruits, and immediately thereafter fermenting the seeds and processing said parenchymatous part. Preferably the fruits are pretreated, for instance, with an alkaline solution and, after peeling, are neutralized, or they are pretreated with a preserving agent. The parenchymatous part of the fruits is expressed to yield the fruit flesh juice containing a hydrocolloid which has proved to be a valuable emulsifying, thickening, stabilizing, suspending agent and protective colloid. The expressed Theobroma fruit flesh is converted into a nutritious animal feed, especially for small animals. Thus the Theobroma fruits are substantially completely utilized.

Abstract: A structural element is provided which is preferably made of metal or plastic and which is useful as load-bearing element of high bending strength for various structures, supports, bridges, vehicles, as load-bearing foundation, and for many other purposes. Such structural element consists of two or more shells or plates which surround at least one cavity. Said cavities are equipped with load-bearing supporting elements, shells, panels, and the like which are associated with pressure plates, preferably honeycomb or grid-like plates. The ribs or ridges of said honeycombs or grids are relatively small, i.e. very narrow. The structural element, furthermore, comprises at least one flexible or movable plate which exerts a pressure onto the elements inserted into the cavity or cavities. Said pressure is equal to or greater than atmospheric pressure and higher than the pressure in the support cavity. The structural element of this invention may also be of tubular shape.

Abstract: The process of separating citric acid and/or isocitric acid and their salts from aqueous solutions containing said acids or their salts, and especially from fermentation solutions, consists in contacting said solutions under pressure with a permselective membrane. The material composing said membrane has introduced thereinto acid or basic groups so as to yield membranes of predetermined swelling power. Preferred membranes are those consisting of polyimide or polyamide polycondensation products which are modified by acid or basic groups, of polysulfones modified by acid groups, or of vinyl polymers modified by acid or basic groups. Adjustment of the starting solutions to a pH lower than 3.0 is advantageously effected by means of polyvinylsulfonic acid.

Abstract: Novel ethynylindenyl compounds and derivatives are described. Their use in the treatment of inflammation is also disclosed.

Abstract: A loadbearing construction element consisting of outer shells which define an air-tight cavity in which is supported insulating elements which form collectively an inner unit. Means are provided for evacuating the cavities of the inner unit and for subsequently pressurizing the components of the inner unit to form a composite core the components of which are fixedly connected to each other. Pressure against the components of the inner unit can be increased by adjustable screws extending through the outer shell into contact with a pressure plate forming part of the inner unit. In this manner, stresses in the element are created so that the outer shells and the components of the inner unit are reinforced and rendered resistant to bending.

Abstract: A therapeutic composition of methaqualone and the like quinazolinone compounds or their acid addition salts per se or in combination with other therapeutic agents, said composition containing solubilizing adjuncts and being rapidly and readily absorbed, and methods of making and using same.

Abstract: An improved heat and cold insulating flexible composite element comprises at least one radiation chamber with walls of flexible material having reflecting surfaces. Opposite walls of said chamber are resiliently spaced from each other by suitable spacing elements.Preferably the chambers are enclosed by an envelope which may also be formed of flexible reflecting sheets.

Abstract: Novel 1,4-bis-formyl cyclohexane polycarboxylic acids have proved of considerable value as agents capable of preventing and inhibiting scale formation in aqueous media. Especially valuable scale formation inhibiting and complexing agents are 1,4-bis-formyl cyclohexane-1,2,3,6-tetracarboxylic acid and 1,4-bis-formyl cyclohexane-1,2,3-tricarboxylic acid. They are prepared by oxidizing the corresponding bicyclo-(2,2,2)-octene(7) polycarboxylic acid-2,3-anhydrides. The novel nitrogen- and phosphorus-free acids have a surprisingly high threshold effectiveness and can be used in detergent and cleaning solutions in combination with conventional detergents and cleaning agents.

Abstract: A fluorophosphate glass of a high positive anomalous partial dispersion .DELTA..nu..sub.e within the range of from about +10.0 to about +21.0, a relatively high index of refraction n.sub.e within the range of from about 1.47 to about 1.54, and an Abbe number .nu..sub.e within the range of from about 84.1 to about 51.0 is provided. A simple process of melting such a glass is disclosed.

Abstract: Scale formation as well as deposition of incrustations in aqueous systems are prevented by the addition of a monophosphoric acid ester of a hydroxy alkyl urea compound or of salts of such an ester. Preferred esters of this type are the esters obtained by reacting hydroxyl alkyl urea compounds with urea phosphate. The esters are highly effective even when they are added in substoichiometric amounts calculated with respect to the scale and hardness causing compounds present in aqueous systems.

Abstract: The invention relates to a method for the resistance welding of sheet metal coated with layers, wherein firstly electrical contact is established between the sheets to be interwelded and between the welding electrodes and said sheets, and subsequently welding is effected across the coating layers. The invention relates also to machines for carrying out this method.

Abstract: N-acyl-1-amino alkane-1,1-diphosphonic acids or their alkali metal salts are highly effective scale and deposit formation preventing, metal ion complexing, sequestering, and anti-corrosive agents which can be used with great advantage in washing and cleaning fluids and detergent preparations. Such N-acyl-1-amino alkane-1,1-diphosphonic acids are prepared, for instance, by acylating the corresponding 1-amino alkane-1,1-diphosphonic acids or by hydrolyzing the corresponding (1,1-diphosphono alkane) acylamidines.
