IPC: F21V21/10
Filed: 1993-10-26
Abstract: ABSTRACT OF THE DISCLOSURE           A lighting assembly for luminaries and the method of  installation wherein the base or pedestal  is readily interchangeable with the pole.  An anchor plate is mounted in the bottom of the pole and has a plurality of mounting bolts threadably engaged in holes formed in the anchor plate.  An equal number of keyhole-shaped slides are formed in a mounting plate located on the top of the base.  Each keyhole-shaped slide has an aperture which is larger than the diameter of the bolt head and an arcuate slot extending outwardly therefrom having a width smaller than the size of the bolt head.  The pole is lowered onto the base and the head of the bolt passes through the aperture of the keyhole-shaped slide.  The pole is then rotated to align the ornamental features of the pole with that of the base with the bolt shaft moving along the narrower slot.   The bolt is tightened to clamp either the bottom of the pole against the base or the anchor plate of the pole against the mounting plate of the base, by the head of the bolt clamping against the bottom surface of the base mounting plate.

Patent CA-2123359-A1 (CA)
Inventor: KOLIN KEVIN S
IPC: C07F7/22
Filed: 1994-05-11
Abstract: This invention provides a method for reducing fifty-fold the size of equipment required for making a given volume of alkyltin thioglycolic acid esters.  In said method,  an alkyltin thiocarboxylic acid ester is made from the corresponding alkyltin halide and thiocarboxylic ester  in a continuous process that requires but one agitated reaction vessel.  The organic reactants and an acid acceptor are added simultaneously to a reaction vessel equipped with agitator impellers and containing a sufficient level of water to provide an agitatable medium.   Extremely vigorous agitation  (at  least about 75 turnovers per minute,  which is sufficient to achieve a fluid velocity across the impeller(s) of at least about 50 feet per minute) is employed to avoid side reactions which often cause the formation of a tenacious, stringy emulsion, the breaking of which requires a rather difficult and wasteful filtration.   Continuous withdrawal of the reaction mixture from said reactor  is commenced promptly after commencement of the additions and said mixture  is continuously separated  into an aqueous phase and an organic phase as it is withdrawn without the need of demulsification means.  The pH of the reaction mixture is greater than 7 but the maximum is about 8.2 and the temperature is from about 40 to about 80°C.

Inventor: KURIHARA MASAHIKO
IPC: A61K31/52
Filed: 1994-06-29
Abstract: ABSTRACT      To stabilize the active ingredients, a caffeine is incorporated into a solid pharmaceutical preparation comprising a dextromethorphan and a phenylpropanola-mine.  The pharmaceutical preparation may further com-prise ibuprofen.  The active ingredients may be further stabilized, in combination with the incorporation of the caffeine, by grouping and incorporating separately each or suitably combined plural of the active ingredi-ents into different groups or by minimizing the amount of any reducing sugar such as lactose.  The solid phar-maceutical preparation is practically valuable since decomposition of each active ingredient with the lapse of time is remarkably suppressed and the active ingre-dients are stabilized for a longer period of time.

Title: Process and device for the separation of an unsaturated hydrocarbon from a fluid mixture with other hydrocarbons
Inventor: CREUSEN RAIMOND J M
IPC: C07C7/152
Filed: 1994-07-13
Abstract: A fluid mixture from which an unsaturated hydrocarbon has to be separated, is passed in the first stage at superatmospheric pressure to one side of a first semiselective gas separation membrane with a non-porous active layer, and a liquid complexing agent is passed along the other side of said first membrane, where said unsaturated hydrocarbon is bound through complexation in the interface of membrane and complexing agent. In the second stage said unsaturated hydrocarbon is dissociated from the complexing agent through temperature increase, the mixture of complexing agent and dissociated unsaturated preferably is passed at superatmospheric pressure to one side of a second semiselective membrane with a non-porous active layer and the unsaturated hydrocarbon migrates to the other side of the membrane and is discharged. Finally, the complexing agent is recycled.

Title: Contenant reutilisable a volume variable
Inventor: ASSELIN DANIEL
IPC: B65D21/08
Filed: 1995-03-28
Abstract: Un contenant réutilisable comprenant une chemise cylindrique ouverte aux deux extrémités, dont une des extrémités est conçue pour y adapter un bouchon ou un couvercle, et une tête de piston cylindrique s'ajustant à l'intérieur de la chemise cylindrique pour ainsi former un réservoir, remplissable par l'une des extrémités et réutilisable, pouvant contenir, par exemple, un produit liquide ou semi-liquide, où la tête de piston cylindrique peut se déplacer longitudinalement à l'intérieur et entre les deux ouvertures de la chemise cylindrique pour expulser totalement ou en petites quantités le produit contenu dans la chemise. Les contenants rigides à cavité creuse sont largement utilisés à titre d'emballage, pour exposer des produits à la vente, ou comme appareil distributeur de ces produits, et sont souvent fabriqués en plastique ou en verre, par exemple. Avec l'utilisation de la matière plastique, des contenants ont été conçus pour être déformés par une compression des parois permettant ainsi l'expulsion par une orifice du produit contenu. Ce type de contenant est actuellement très répandu sur le marché pour une grande variété d'utilisation. Une autre façon d'expulser un produit est en permettant la déformation ou le déplacement du fond du contenant. Ainsi, certains de ces contenants rigides sont munis d'un réservoir, contenant un produit à être consommé, dans lequel l'utilisateur fait déplacer un piston qui expulse le contenu du réservoir par un orifice. Le brevet américain 2,839,928 de S. F. Fohrman (juin 1958) illustre bien le principe dont il est question ici, mais dans une application réutilisable dédiée à la mesure d'un volume. D'autre part, le brevet américain 3,325,063 de B. Hansen (juin 1967) décrit un système semblable utilisant un mécanisme particulier où un produit placé dans un réservoir est expulsé par l'action rotative d'une tête de piston à l'intérieur du réservoir. Ces types de contenants sont habituellement vendus avec un contenu pré-empaqueté dans le réservoir, et sont jetables entièrement ou en partie. C'est également le cas du produit décrit dans le brevet canadien en instance 2,109,539 de M. Boiardi (novembre 1993). Ce type de produit, où certaines composantes sont jetables, oblige la multiplication des pièces, limite la diversité des utilisations d'un même contenant, empêche la réutilisation de ces composantes, et est incompatible avec des préoccupations contemporaines qui cherchent à réduire le nombre de produits à utilisation unique sur le marché de la consommation, et qui favorisent les produits pouvant être recyclés, réutilisés et récupérés. De plus ce dernier produit omet complètement la possibilité d'une utilisation avec un bouchon ou un couvercle qui permet la réutilisation du produit dans des usages multiples.
