Patent YU-82289-A (YU)
Title: Animals breeding device
Inventor: HELMUT BUGL
IPC: A01K1/02
Filed: 1989-04-20
Abstract: The invention relates to an arrangement for accommodating livestock, in particular pigs, in which the animals are accommodated individually, or several together, in sleeping boxes so that they can only lie side by side and primarily only in one direction, or in some cases also in opposite directions. The arrangement can have air intake, air circulation and/or waste air devices by which the air is treated in accordance with the animals' requirements. An essential feature is that an aperture (4) is provided on at least one side (3) of the sleeping box through which the animal can on its own initiative move its head into a region outside the sleeping box. The aperture (4) is provided with a single or multiple curtain (5). The device has the advantage that the warmer region surrounding the body of the animal is formed separately from the head and respiration region, and that the air conditions in these regions can be separately adjusted.

Abstract: PROTECTOR FOR ELECTRIC CIRCUITS             ABSTRACT OF THE DISCLOSURE:  A current-limiting, single-element, dual-function, electric fuse has a fusible element with at least one "weak spot" of very small cross section; and the temperature of that weak spot will exceed eighty percent of the melting temperature of the material of the fusible element when that electric fuse operates at its maximum continuous current carrying capacity. Because the temperature of that weak spot is so close to the melting temperature of the material of that fusible element, that weak spot can quickly melt and interrupt the circuit through the electric fuse in response to a low but potentially-harmful overload.  The weak spot can be given a very small cross section, and it can be permitted to operate at temperatures close to the melting temperature of the material of the fusible element, because the housing for the electric fuse and arc-quenching filler within that housing dissipate large amounts of the heat which is generated by that weak spot.  Specifically, an appreciable amount of the heat, which the weak spot generates in response to a low but potentially-harmful overload, will be conducted to the inner surface of the housing for the electric fuse by the arc-quenching filler; and a substantial percent of that conducted heat will pass to, and be radiated by, the exposed outer surface of that housing.  The conduction of heat to the inner surface of the housing is fostered by locating the weak spot closer to that inner surface than to either terminal of the electric fuse; and the passing of that heat to the exposed outer surface of that housing is fostered by making that housing of a material which has a thermal conductivity in excess of thirty thousandths of a calorie per square centimeter of cross section per centimeter of length per second of time per degree centigrade.

Abstract: ABSTRACT OF THE DISCLOSURE             An electrostatographic machine is provided with a manually operable switch for changing the output of a pre-transfer corona discharge device depending upon the contrast characteristic of an original document to be copied. If the pre-transfer device is energized by an A.C. signal biased to a preselected D.C. level, this D.C. bias level may be changed in accordance with contrast quality of the original document to vary the image density at which transition from transfer suppression to transfer enhancement takes place. Alternatively the A.C. excitation level may be varied to change the point at which transition from transfer enhancement to transfer suppression occurs.

Abstract: Abstract of the Disclosure Siloxane foams which are activated and cured by heating can be prepared by mixing an organohydrogensiloxane, a hydroxylated organosiloxane and a rhodium catalyst in amounts such that the ratio of silicon-bonded hydrogen atoms to silicon-bonded hydroxyl radicals is from 2.5/1 to 40/1 and thereafter heating the mixture above 90°C. The rhodium catalyst provided a pot life of at least 8 hours when used in amounts of 0.0025 grams per 100 grams of hydroxylated organo-siloxane.  The siloxane foams can be made to have an increased fire retardant property by adding 0.01 to 2 parts by weight carbon black based on the weight of the total composition.  Siloxane roams are also prepared from mixing an organohydrogensiloxane, a hydroxylated organosiloxane, a vinyl containing triorganosiloxy endblocked polydiorgano-siloxane and a rhodium catalyst.  These foams can be used for cushioning, in acoustical applications and protective filling or coating applications and especially applications wherein fire retarding is important.

Abstract: ABSTRACT OF THE DISCLOSURE           A continuous, low cost method of concentrating dilute streams containing fractions of adsorbable chemicals is dis-closed which minimizes heat consumption and provides highly con-centrated supplies of valuable chemicals which are suitable for reuse or sale without substantial further processing.  The meth-ods hereof are particularly adapted for concentrating waste con-densates derived from pulp-making operations such as the Kraft or sulfite processes, but in general are also applicable for treating a wide variety of dilute organic or inorganic adsorb-able chemicals.  The invention involves initially adsorbing and concentrating a chemical fraction from the dilute stream followed by desorption and recycling of the adsorbed materials to further concentrate the same whereupon the desorbed chemicals are direc-ted to a second concentration zone and concentrated therein; at this point the partially concentrated steam is diverted back to the adsorption zone for further adsorption and concentration simultaneously with the dilute stream initially passing there-through, while concentration continues in the second zone to yield a final product having a concentration on the order of 90% by weight or better.  In preferred forms only a single fraction-ating column is employed in the second concentration stage which minimizes capital costs and reduces steam consumption, while recycling back to the adsorption zone permits continuous opera-tion of one fractionation column doing the work of two or more columns.  Thus, dual use of the single fractionator column in both intermediate and final concentration steps allows contin-uous operations with equipment heretofore used only in batch-type operations.

Abstract: Abstract of the Disclosure This invention pertains to improvements in the manufacture of soda-lime glass from pelletized glass batch material in which a major portion of the alkali metal oxide flux material (e.g. Na20) in the final glass is derived from an alkali metal hydroxide (e.g. NaOH) and in which the alkali metal hydroxide is reacted with alkaline earth metal oxide source material (e.g. limestone) during the preparation of the pelletized glass batch mater-ial.  The improvements are obtained by reacting aqueous, concentrated alkali metal hydroxide with at least a portion of the alkaline earth metal oxide source material to form an aqueous slurry which contains the reaction products, then mixing with the slurry the remaining glass batch materials under conditions to assure thorough mixing and then pelletizing and heating the batch material at a temperature of at least about 145°C to assure sub-stantially complete drying of the pellets and substantially complete reaction of the alkali metal hydroxide.
