Patent ES-8302286-A1 (ES)
Title: Furnace for heating slabs, billets, rough castings and the like
IPC: F27B9/38
Filed: 1982-01-15
Abstract: A furnace for heating all sides of products such as metal slabs, billets, rough castings and the like includes a furnace chamber having a charging end and a discharging end. A plurality of carriages are positioned throughout the length of the furnace chamber to support products to be heated and are sequentially movable through the chamber from the charging end thereof to the discharging end thereof. Each carriage includes a support bench having extending upwardly therefrom support members to directly contact and support the products to be heated. A charging station is located adjacent the charging end of the furnace chamber for loading a product to be heated onto the carriage and introducing the thus loaded carriage into the furnace chamber, thereby displacing loaded carriages within the furnace chamber toward the discharging end and discharging a downstream-most loaded carriage from the discharging end of the furnace chamber. An unloading structure is located adjacent the discharging end for unloading a heated product from the carriage discharged from the discharging end. A return chamber extends from adjacent the unloading structure to the charging station to enable the unloaded carriage to be returned to the charging station. A heat insulation device within the return chamber reduces heat loss from the unloaded carriage while in the return chamber.

Title: Novel prostaglandin analogues and process for making same.
IPC: C07D301/03
Filed: 1982-03-01
Abstract: A novel process for the oxidation of olefins to the corresponding alpha-epoxy alcohols which can be incorporated in the total synthesis of members of a novel class of prostaglandin analogues. Olefins are reacted with singlet oxygen in the presence of a group IVB, VB or VIB transition metal catalyst, excluding chromium. The reaction is fast and highly selective to the alpha-epoxy alcohol. When cyclopentene is oxidized in the process of the invention, high yields of cis 2,3-epoxy-cyclopentan-1-ol are obtained. The latter compound is used as a starting material in the synthesis of prostaglandin analogues. The prostanoids of the invention are characterized by an oxa group replacing the methylene group at the 7-position, and the absence of a hydroxyl or other substituent at the 11-position. Members of this class of prostanoids show important cytoprotective properties in animal tests.

Patent ES-8307556-A1 (ES)
Title: Device for transversely conveying strand cuts from a multi-continuous-casting plant.
IPC: B65G47/32
Filed: 1982-06-30
Abstract: For a multi-strand continuous casting installation there is proposed accomplishing the transverse conveying or transfer of the cut strand sections, not as was heretofore conventional practice by a single clearing or removal movement occurring over the entire width of the installation, rather by a number of successive partial conveying strokes or movements, wherein the strand section is displaced from its starting position either through the distance (s) or the distance (s'). Consequently, there is required for each strand section a number of shorter partial conveying strokes or displacement movements corresponding to the ordinal number of the strand from which it is derived, and thus, during cutting of shorter strand sections the clearing time can be better accommodated to the cycling of the cutting operation. The displacement paths, depending upon the technique employed, amount to either s=dx(N-1)/N or s'=dxN/(N+1), wherein N constitutes the number of strands and d their spacing. The apparatus for performing the method contains transport carriages possessing pivotable pawls which perform the displacement paths driven by a lever mechanism.

Filed: 1982-10-14
Abstract: EP--98913 A (+22.3.82, 13.4.82, 23.8.82 (2), 14.10.82, 7.12.82, 15.12.82, 21.12.82 (3) 24.12.82 (2) -ES- 510664, 511397, 515186, 515187, 516506, 518012 518238, 518343 (5) (6), 518567, 518568)  The device is disposed on or in an object to the protected and the conductive sphere is caused to be positioned in a given zone (D1) where it causes closure of either switch of a pair of switches but not both switches simultaneously. The interval between the intants of closure of the two switches represents the amplitude and rapidity of movement of the object. Slight displacements or vibrations will not cause both switches to close due to the distance separating them but sudden violent displacements caused by a bag being snatched will cause an alarm. - The switches may be constituted by interdigitated printed conductors on a circuit board, the spacing between the conductors being such as to allow them to be bridged by the conductive sphere. Various forms of electronic monitoring circuit are described to trigger an alarm device in response to the two switches being closed in response to violent movement of the conductive sphere, using bistable circuits. The path has zones of differing curvature to provide a variation of the movement sensitivity.  (4/55)

Title: Process for obtaining transfer factor from colostrum, transfer factor so obtained and use thereof.
IPC: C07K14/52
Filed: 1984-11-23
Abstract: Antigen specific excreted transfer factor may be obtained by collecting material, e.g. colostrum or milk, secreted by the mammary gland of a suitable lactating mammal, e.g. a cow having immunity to the antigen under suitable conditions such that materials which interfere with transfer factor efficacy are removed so as to obtain transfer factor. Colostrum or milk so collected may be used directly, typically after sterilization, or may be treated to further concentrate and/or purify transfer factor. Treatment to yield colostral whey containing transfer factor is presently the preferred method for obtaining transfer factor for use in conferring immunity against diseases associated with antigens for which the transfer factor is specific. Cell-associated transfer factor specific for an antigen may also be obtained by incubation release from, or lysis of, cells obtained from the collected material. An alternative method for obtaining transfer factor is to recover it from the mammary tissue of a suitable lactating mammal. The transfer factor may be used in edible compositions and in pharmaceutical or veterinary compositions and in methods for conferring immunity in a human or lower animal to a disease associated with the antigen. The transfer factor may then be used to prevent or treat the disease.
Patent ES-8602316-A1 (ES)
Title: Tri-level sandcastle pulse decoder.
IPC: H04N9/44
Filed: 1984-12-07
Abstract: The decoder includes a pulse source (11) for supplying a train of trilevel pulses to the input terminal (I) of an integrated circuit carrying chrominance and luminance signal processing circuits of a receiver. Pulses at a level above a base level provide positive-going retrace blanking pulse components. Pulses at a second higher voltage provide burst gating pulses, and pulses at a third intermediate voltage level form kinescope bias control interval timing pulses. A voltage comparator (30) compares the train of pulses with a reference lvel which is between the first and intermediate voltage levels. A second voltage comparator (40) compares with pulse train with a second and lower voltage reference. A keying pulse is produced when the level of the trilevel pulse train is above the second reference voltage level. - A control transistor (73) is arranged to receive the keying pulse, and response to the output of the first voltage comparator so as to prevent production of the keying pulse when the trilevel pulse train is at the higher voltage level.
