Patent CA-2069237-A1 (CA)
Inventor: FATTORI JOSEPH E
IPC: B26D1/02
Filed: 1992-05-22
Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed is a method and apparatus for shaping a top surface of a product, such as an antiperspirant or deodorant product, to have a compound-curved shape.  The apparatus includes at least one cutting blade which moves inward and outward in a second direction while the product passes by in a first direction perpendicular to the second direction, such that the cutting blade cuts the top surface of the product to have a desired profile in the first direction.  The cutting blade itself can have a desired profile along a third direction perpendicular to the first and second directions, to impart to the top surface of the product a desired profile in the third direction.  A plurality of cutting blades can be used, to incrementally remove product material to form a final shaped product surface.  The product cut off in forming the shaped surface can be reclaimed for refuse.  The apparatus can also include stationary blades, and can be used to form a product having a shaped top surface with a profile having different radii of curvature in the same direction.

Title: Methode de fracturation de formations geologiques et composition de fluides hydrauliques utilisee a cette fin
Inventor: WESTLAND JOHN A
IPC: E21B43/267
Filed: 1990-12-11
Abstract: L'addition de quantités relativement petites d'une cellulose bactérienne à des fluides de fracture hydraulique améliore leurs propriétés rhéologiques pour la cassure hydraulique de formations géologiques. Une suspension d'étançonnement est considérablement améliorée et les pertes de friction dans les cuvelages des puits sont réduites de manière significative, ce qui se traduit par des besoins en énergie de pompage moindres. Des modèles informatiques indiquent si les fractures de la formation se propageront sur des distances plus grandes que la partie étançonnée de la fracture. Normalement, uniquement environ 0,60 à 1,8 g de cellulose bactérienne par litre de fluide de fracture est nécessaire. Une cellulose bactérienne préférée est produite dans des cuves de fermentation avec agitateur en utilisant des souches résistantes à la mutation d'une bactérie provenant du genre Acetobacter.

IPC: F15B21/0423
Filed: 1990-11-05
Abstract: The present patent application refers to a device for the improvement of the running conditions in a hydraulic installation or in so-called hydraulic system. The device contains a central circulating circuit separated from the influence of the atmosphere. To the circulating circuit are connected an outlet and an inlet for the connection of the hydraulic fluid to the other parts of the hydraulic system. The mentioned circulating circuit is divided into at least two chambers separated by pressure generating respectively pressure reducing units (3, 4, 5). The first chamber (1) is to a certain extent an expansion room for the hydraulic fluid in the system which is separated from the atmosphere and it forms a low-pressure part in the circuit. The second chamber (2) forms a high-pressure part which directly or indirectly is connected to the said outlet. The circulating circuit holds medium (4, 13) for the cooling and filtering of the hydraulic fluid.

Title: Method of treating air with discs in multilayer structure
Inventor: HARAGA HISATO
IPC: B01D53/06
Filed: 1991-11-27
Abstract: ABSTRACT            Processes for treating air in order to decompose or remove foreign matter contained in the air or to add a functional agent to the air, by use of rotatable circular plates stacked in a multi-layered form.  Rotation of the circular plates causes thin air layers between the circular plates to exhibit a self-blowing function, whereby an air-blowing function is added and the treatment of air by the air-treating function of the plate surfaces is promoted.  It is therefore possible to cause separation of laminar Plow, a promoted turbulence of boundary layers near the plate surfaces due to increased velocity of air relative to the circular plates, propagating stall, etc. in the thin air layers.  These phenomena enable marked activation of the contact between air flow and catalyst, adsorbent or the like which is supported on, infiltrated in or otherwise possessed by the multiplicity of circular plates according to the intended use of the multi-stacked plate assembly.  Thus, the air treatment performance is improved markedly.  Further, the rotation of the circular plates increases the distance of contact with air and causes the air to flow along a curved line resembling a logarithmic spiral relative to the circular plate, so that even where the spacing between the circular plates is nonuniform, there is little possibility of a steady drift being developed with respect to the circumferential direction, and the entire surface area of each circular plate can be utilized effectively.  This also contributes to an enhanced air-treating function and an improved performance.  Moreover, even where the spacing between the rotatable circular plates stacked in multi-layered form is reduced in order to increase the area of contact between air and the functional agent, an attendant increase in the self-blowing function due to the rotation of the circular plates ensures a marked promotion of the air-treating function, without any reduction in the flow rate of air through the air-treating assembly.

Title: Process for the storage and transportation of liquid hydrocarbons
Inventor: ENGELHARDT FRITZ
IPC: C10L7/00
Filed: 1992-09-08
Abstract: ABSTRACT        The present invention relates to the use of hydrocarbon-rich gels as a safe storage or transportation form for liquid hydrocarbons and to a process for the safe storage and safe transportation of liquid hydrocarbons.  In the process according to the invention, the hydrocarbon is converted into a hydrocarbon-rich gel by addition of a surfactant and water.  After storage or transportation has taken place, the hydrocarbon-rich gel is broken down again.  The surfactant and water are preferably added to the hydrocarbon in amounts such that a hydrocarbon-rich gel of 70 to 99.5% by weight of hydrocarbon, 0.01 to 15% by weight of surfactant and 0.49 to 15% by weight of water is formed.  The gels are distinguished by a flow limit, which means that although they can be pumped in a simple manner, they cannot flow in the state of rest and therefore cannot be accidentally discharged from defective storage or transportation tanks, thus considerably reducing environmental hazards due to storage or transportation of hydrocarbons.
