Inventor: DORNBUSCH ARTHUR H
IPC: A61K8/00
Filed: 1992-08-28
Abstract: A swivel up package (1) for a deodorant or antiperspirant having specialized sealing (31, 32, 61) which prevents leakage of product, in eith-er its molten or volatile state, during manufacture, shipment and storage by containing all of the product within or above the elevator (30).  The preferred package (1) has a body (5) of an oval or circular cross-section with an open top and a closed bottom (12).  The bottom (12) has a central-ized aperture adapted to receive a spindle (19) having a screw shaft (20) disposed within the body (5) and a dial or handwheel (22) disposed out-side the body (5).  Also disposed within the body (5) of the package (1) is the elevator (30) having a threaded central hub (35) that is in engagement with the screw shaft (20).  The periphery of the elevator (30) is sealed along the internal surface (6) of the body (5) of the package (1).  Further sealing (61) is provided between the hub/threaded shaft (20) interface when the elevator (30) is in its lowermost position. The elevator (30) has a reservoir (55) to receive molten product during the fill process.  The seals (31, 32, 61) are such that flow of air and molten product to the reservoirs (55) is possible only through the top of the package.  The volumetric ca-pacity is at least as great as the volume intermediate the fill line of the package (1), filled in its upright condition with the product in a molten or liquid form, and the inner surface (85) of a forming means (73) used to shape the top of the product.  There is also provided a fill/invert process for manufacturing a cosmetic stick-type product using the package (1) de-scribed above.

Title: A method for the enzymatic treatment of chemical pulp before bleaching
Inventor: KAWABATA HARUHIKO
IPC: D21C5/00
Filed: 1994-01-21
Abstract: ABSTRACT    Provided is a method for enlarging the degree of delignification in chemical pulping without lowering the viscosity of the resulting pulp.  According to the method, an unbleached pulp or an oxygen-delignified pulp is held in an acidic condition before bleaching and treated with a xylanase exhibiting the activity at pH 4.5 or less.

Patent CA-2132622-A1 (CA)
Inventor: KENNEDY CHRISTOPHER R
IPC: C09K3/14
Filed: 1993-04-01
Abstract: The present invention generally relates to mechanisms for preventing undesirable oxidation (i.e., oxidation protection mechanisms) of reinforcement materials in composite bodies. The oxidation protection mechanisms include getterer materials which are added to the composite body which gather or scavenge undesirable oxidants which may enter the composite body. The getterer materials may be placed into at least a portion of the composite body such that any undesirable oxidant approaching, for example, a fiber reinforcement, would be scavenged by (e.g., reacted with) the getterer.  In a preferred embodiment of the present invention, the getterer material(s) form at least one compound (e.g., at least one glassy material) which acts as a crack sealant, thereby further enhancing the oxidation protection of the composite body. One or more ceramic filler materials which serve as reinforcements may have a plurality of superimposed coatings thereon, at least one of which coatings may function as a getterer. The coated materials may be useful as reinforcing materials in ceramic matrix composites to provide improved mechanical properties such as fracture toughness.  The present invention also relates to improved composites which incorporate these materials, and to their methods of manufacture.

Title: Anti-theft security lock
Inventor: VENETTACCI ALDO
IPC: E05B65/00
Filed: 1994-09-26
Abstract: In a double bar locking system it is known that security is maximized compared to the single bar locking system, since the double bars prohibit entry when attempts of removing the hinge pins from the exterior side of a door or forcing a door fail. However, this does not prevent the determined burglar to enter the premises through a window and then to open the secured door from the inside allowing more items to be stolen and easing the escape. It is the object of this invention to prevent this situation. The present invention provides a double bar locking system and prohibits the tampering of a locked door from both sides of the door. Thus, if a burglar should gain entry by breaking a window, the burglar's only recourse to fleeing would be through the window, thus encumbering and retarding the burglar's actions and limiting what can be taken from the premises. It is the object of this invention to provide a device which is small, lightweight, attractive, easy to manufacture and install. The present invention is designed with the minimum amount of material which allows simple manufacturing and effortless assembly. This locking device can be installed in many ways: horizontally, vertically, within or on the door, at any location. The installer is not limited to the type of door he can choose from when installing such a device. Thus, securing a door can be achieved with the minimum amount of cost and time. It is the object of this invention to allow the key locking cylinder to be easily replaced, whereby the owner of the premises can choose from a variety of cylinders ranging from simple, inexpensive mechanisms to complex and expensive ones depending of the required security.            Specification A locking device for use on any door to provide security against unlawful or unauthorized entry. The unit consists of a box which houses an actuator mechanism which retracts or advances a pair of toothed locking bars which travel along a common center gear. The rotation of the gear is controlled by a lock cylinder which turns with a key. Each locking bar within the housing is attached to a longer bar, exterior to the housing, which enters a receiver at the door's frame. The lengths of the additional bars vary depending on the size of the door; and the location and orientation of the housing. For clarification purposes, the front of the door will represent the side which is located outside the premises, while the back of the door will represent the side which is located inside the premises. The present invention relates to an improved double bar lock system as described herein with reference to the accompanying drawings which:

Inventor: THEVENON ALAIN
IPC: B60L9/18
Filed: 1994-12-12
Abstract: Système d'alimentation d'une locomotive multicourant à 2N moteurs, avec N supérieur ou égal à 2, comprenant 2N paires de convertisseurs de tension (Bi1 et Bi2) associés respectivement aux 2N moteurs, chaque moteur Mi étant alimenté au moyen d'un onduleur connecté aux bornes d'un condensateur de charge (Ci). Lorsque l'alimentation de la locomotive est en courant alternatif, chacune des paires forme un convertisseur 4 quadrants dont les deux parties sont reliées par l'enroulement secondaire (Si) d'un transformateur dont l'enroulement primaire est connecté directement aux bornes de l'alimentation alternative. Lorsque la locomotive est alimentée en courant continu, des commutateurs (Hi1 et Hi2) permettent d'utiliser les convertisseurs de tension soit comme hacheurs abaisseurs de tension, soit comme hacheurs élévateurs de tension. Ce système d'alimentation est conçu de telle sorte qu'en cas de défaillance d'un convertisseur ou onduleur, il suffit de l'isoler tout en conservant les autres fonctionnalités. La disponibilité est considérablement améliorée car, même en cas de défaillance, on conserve l'effort sur au moins 3 moteurs.
