Patent EP-0134924-B1 (EP)
IPC: C10G11/14
Filed: 1984-06-19
Granted: 1987-12-09
Abstract: The invention is particularly concerned with controlling the two stage regeneration temperatures of the RCC residual oil cracking unit below 760 DEG  C. (1400 DEG  F.) by effecting a first stage regeneration with direct injection of water in an oxygen lean atmosphere to product CO rich flue gases under temperature conditions restricted not to substantially exceed 732 DEG  C. (1350 DEG  F.) preferably less than 732 DEG  C. (1350 DEG  F.) thereby partially regenerating the catalyst. The partially regenerated catalyst is withdrawn and directly cooled with boiler feed water to produce steam in an external catalyst cooler before passing the catalyst to a second stage catalyst regeneration for contact with an oxygen rich atmosphere restricted not to exceed 760 DEG  C. (1400 DEG  F.) and preferably maintain less than 760 DEG  C. (1400 DEG  F.). The catalyst regenerated by this technique comprising residual coke less than 0.25 wt % is passed to a riser conversion zone for catalytic cracking residual oil feeds.

Title: Supporting arrangement for rollers, especially for supporting conveyor belt rollers
IPC: F16C23/08
Filed: 1984-07-19
Granted: 1988-03-16
Abstract: According to the invention, an inexpensive antifriction bearing is located in a plastic block and the plastic block is encircled by a further plastic ring. The softening point of the plastic ring is lower by 20 DEG  C. than that of the material of the bearing block and between the softening point and melting point of the ring a difference of at least 30 DEG  C. exists ensuring that in case of excessive warming up of the bearing, the sliding on each other of the plastic block and of the outer plastic ring as plain bearing, puts the bearing out of action for a certain time. The contact surfaces of the bearing block and the ring are spherical, ensuring the compensation of possible eccentricity by self-aligning. The ring is fixed in the seat of a roller by flanging. The invention renders superfluous the otherwise indispensable high-precision single-purpose machine or horizontal lathe for boring the roller, and makes possible the application of the technology of mass production.

IPC: B01D53/94
Filed: 1985-02-21
Granted: 1988-09-28
Abstract: A catalyst composition effective for selective catalytic reduction of nitrogen oxides with ammonia in a gas stream has an upstream section comprising a phosphorus getter comprised of a phosphorus retaining material, e. g., activated alumina, and a downstream section comprising a vanadium oxide containing catalyst, e. g., a vanadia/titania catalyst. It has surprisingly been found that vanadium oxide catalysts are poisoned by phosphorus which may be contained in the form of phosphorus contaminant compounds in the gas to be treated, so that the positioning of a phosphorus-retaining material upstream of the catalyst prolongs catalyst life. In operation, the gas to be treated is passed first through the phosphorus getter upstream section of the catalyst composition and then contacted in the presence of ammonia with downstream section catalytic material.

Title: Lentille polarisee arretant la lumiere bleue et le rayonnement ultraviolet
Inventor: JOHANSEN LAURIE A
IPC: G02C7/12
Filed: 1986-10-16
Granted: 1994-12-28
Abstract: Une lentille (12) arrête sensiblement la lumière polarisée horizontalement et arrête sélectivement des longueurs d'ondes comprises entre 300 et 549 nanomètres. Cette arrêt sélectif est commandé par un filtre à transmission ponctuelle (14) choisi de manière à transmettre à 450, 500, 515, 530, ou 550 nanomètres. Le point spécifique d'arrêt et de transmission choisis est fonction de l'usage/environnement ultime de la lentille (12). Si on choisit un filtre qui transmet à 450, il arrête les longueurs d'ondes comprises entre 300 et 449 nanomètres avant qu'une transmission n'ait lieu à 450 nanomètres; de même, un filtre transmettant à 550 arrête les longueurs d'ondes comprises entre 300 et 549 nanomètres avant qu'une transmission n'ait lieu à 550 nanomètres. La lentille (12) permet également la transmission de 30 à 40 % des longueurs d'ondes au-dessus de 625 nanomètres. Le filtre (14) combiné à un polariseur (16), arrête le rayonnement ultraviolet et la lumière bleue qui sont nocifs. Tandis que le port de lentilles n'arrêtant que la lumière bleue procure un effet bénéfique et apaisant, l'adjonction d'un polariseur (16) renforce sensiblement cet effet apaisant tout en améliorant la vision sans gêne visuelle.

Abstract: On account of the elasticity of leather, making an open structure from a skin or sheet of leather in the present state of the art does not make it possible to obtain a structure in which the strips are all situated in the same plane and which together form uniform meshes. To overcome this disadvantage the skin or sheet of leather (4) is backed, before making an open structure, with a thin sheet (2) of a material with very little elasticity and capable of being made into an open structure without shrinkage. This backed skin or sheet (7) is then made into an open structure and pressed with or without heating, depending on the nature of the substrate. <IMAGE>
