Patent CU-22148-A1 (CU)
Title: Procedimiento para la obtención de aditivos para lubricantes
Inventor: SPENGLER FERNANDEZ BEATRIZ MARIA LUISA
IPC: C01B25/14
Filed: 1988-12-28
Abstract: La composición objeto de la invención se relaciona con el campo de la química y en particular se refiere a un procedimiento para la obtención de un aditivo con acción antioxidante y anticorrosiva para inhibir el deterioro de las grasas y lubricantes cuando se someten a explotación. En la composición intervienen en sustitución de los alcoholes técnicos una o más fracciones de aceite de fusel cuyos puntos de ebullición están comprendidos entre 90 y 138sC, P2S5 , ZnO y aceite base. La novedad de esta invención consiste en el empleo de una o más fracciones de aceite de fusel durante la formación del ácido. Por otra parte, la obtención del ácido se hace utilizando como medio un aceite ligero, la cual hace más controlable la temperatura durante el transcurso de la reacción exotérmica y permite mejor homogeneidad en la mezcla reaccionante sin que este aceite intervenga en la reacción. Adicionalmente seleccionando las proporciones más adecuadas de los reaccionantes y las temperaturas de trabajo se obtienen reducciones apreciables del tiempo de reacción. El final de la reacción de obtención del ácido se hace mediante la determinación del peso equivalente de éste. Luego se procede a la neutralización del ácido con ZnO. Los aditivos preparados poseen excelentes características físico-químicas, tales como contenidos apropiados de P, S y Zn, mostrando además elevada acción antioxidante, anticorrosiva, poseyendo buena estabilidad y solubilidad en los aceites base.

Title: Device for ligand-receptor methods
Inventor: NOWAKOWSKI MARK RONALD
IPC: G01N37/00
Filed: 1991-03-11
Abstract: Devices for use in either competitive or non-competitive ligand-receptor assays, having a microporous member in contact with a non-absorbent textured surface, where the surface texturing is such that a capillary network is formed when in contact with the microporous member. More particularly, these devices comprise: a porous member having an upper and a lower surface, being positioned in the device such that said sample may be applied to said upper surface; and a non-absorbent member having a textured surface with channels capable of forming a network of capillary channels when placed in communication beneath or around said porous member, said capillary network being substantially parallel to the lower surface of said porous member; whereby the sample, alone or in combination with other fluids,when applied to said upper surface is drawn through said porous member to said capillary network formed between said porous member and said non-absorbent member when substantially all the void volume of said porous member is filled with said sample and/or fluids and when contact is made between said porous member and said non-absorbent member. These devices are suitable for use in ligand-receptor assays which are performed using either immunochromatographic methods or in those which are performed using flow-through methods. <IMAGE>

Filed: 2015-02-05
Abstract: L'invention concerne une tôle d'acier comprenant, en % en poids, 0,04 = c = 0,30; 0,5 = mn = 4, 0 = cr = 4; 2,7 = mn + cr = 5; 0,003 = nb = 0,1; 0,015 = a1 = 0,1; et 0,05 = si = 1,0; la composition chimique de la tôle thermoformée rend celle-ci insensible à la vitesse de refroidissement après l'austénisation, et permet d'assurer une distribution uniforme de la résistance à la traction, dans la plage de 800 à 1400 mpa, sur toute l'étendue des pièces, indépendamment du décalage entre les opérations de refroidissement/trempe finale. Par conséquent, une partie formée peut être refroidie à l'air ou pendant qu'elle se trouve dans une matrice. L'ajout de nb permet de réduire la quantité de c nécessaire pour obtenir une résistance à la traction donnée, et d'améliorer la soudabilité.

Title: Improvements in or relating to linear polyamides
IPC: C08G69/26
Filed: 1954-12-14
Abstract: Linear polyamides are formed from oxalic acid and a di-methyl hexamethylene diamine or a mixture of two diamines at least one of which is mono-methyl hexamethylene diamine. In the substituted hexamethylene diamines the methyl groups are in 2, 3, 4 or 5 position. Minor amounts of conventional diamines, dibasic acids, monoaminomonocarboxylic acids or caprolactam may be included in the reaction mixture. Ingredients may be present as amideforming ingredients, e.g. as oxamic esters of the diamines or as diamine-dibasic acid salts. Monofunctional amide forming ingredients may be included as described in Specification 495,790, [Group IV]. Preferably lower alkyl or aryl esters of oxalic acid are used and mixed with the diamine in the cold preferably with a solvent. When the initial reaction ceases, heat is applied to drive off solvent and alcohol formed in the reaction. Final heating may be at 300 DEG C. under reduced pressure. Conventional reaction techniques may be employed. Examples are given employing (1) 3,4-dimethyl hexamethylene diamine (2) a mixture of 3-methyl-hexamethylene diamine with hexamethylene diamine and (3) a mixture of 2-methyl and 3-methyl hexamethylene diamine.

Title: Terminal slowdown control for elevator system
IPC: B66B1/48
Filed: 1973-05-16
Abstract: Terminal slowdown control for elevator systems which includes spaced markers and a detector, mounted for relative movement as an elevator car approaches a terminal. The markers are spaced such that if the elevator car is approaching the terminal with a constant deceleration rate, the combination of the spaced markers and detector will produce pulses at a constant rate. If this constant rate is within a predetermined range, the slowdown is normal. If the rate is faster than a predetermined value, comparison means provides a speed error signal which may be used to initiate terminal slowdown, and the same speed error signal may be used to generate an auxiliary speed pattern voltage for use by the elevator control in bringing the car to a stop according to a predetermined deceleration schedule.
