Patent CA-2101041-A1 (CA)
Inventor: BLUEMEL SIEGFRIED
IPC: C09C1/36
Filed: 1993-07-21
Abstract: In the preparation of a suspension with a high content of titanium dioxide, which has been produced according to the chloride process, a finely divided titanium dioxide is slurried, in unflocculated condition without use of a dispersing agent, dechlorinated and then filtered. The content of multivalent anions can be controlled in the slurry before the filtration through suitable dechlorinating agents, particularly hydrogen peroxide and/or sodium hydrogen sulfite, and thereby the solid content in the filter cake and the consistency of the filter cake are advantageously influenced. If, on one hand, no or only few multivalent anions are present, a thixotropic filter cake with a high solids content is obtained in a pressure filtration. The filter cake is converted into a titanium dioxide suspension with a high solids content through feeding into a titanium dioxide suspension to which a dispersing agent has been added. If, on the other hand, a rigid filter cake is desired by, for example, a vacuum filtration, a minimum quantity of multivalent anions is necessary for the formation of the rigid filter cake. The solids content is, however, lowered in comparison to the thixotropic filter pastes. Where this minimum quantity of multivalent anions is exceeded, the solids content declines further. The rigid filter cakes can be rendered flowable through the direct admixing of dispersing agent. Hydrogen peroxide is particularly preferred as a dechlorinating agent.

Patent CA-2112579-A1 (CA)
Inventor: DUNFORD DAVID V
IPC: B21D26/055
Filed: 1992-07-02
Abstract: The low peel strengths of diffusion bonded joints in aluminium alloy structures has been a bar to their use in superplastic forming. The invention overcomes this disadvantage by creating a workpiece intended for subsequent superplastic forming by dif-fusion bonding an assembly of alloy sheets (30-32) in bonding zones according to a predetermined pattern and providing reinfor-cing material (33) in the workpiece in the region of the diffusion bonded zones. The reinforcing material serves to prevent the ten-sile stresses exerted during subsequent superplastic forming from initiating peel fracture of the diffusion bonds. Instead, the tensile stresses act so as to bring about superplastic deformation in those regions of the workpiece between the diffusion bonded zones.

Abstract: A new and improved apparatus (9) for illuminating the rear portion of a vehicle (14) and particularly the license plate (14A) of such a vehicle (14) with a bright glowing light. The apparatus (9) includes a transparent channel member (30) for receiving a high voltage high frequency transformer (21) and a single annularly shaped neon bulb (20) therewithin for illumination purposes. The neon bulb (20) is energized by the high voltage, high frequency transformer (21) that is coupled to the vehicle electrical system (10) by a low voltage high frequency power supply (12). The channel member (30) is adapted to be mounted adjacent to the license plate (14A) of a vehicle (14) and sealed with a protective cover (40) to help prevent accidental shock and to protect the bulb (20) from exposure. The preferred method of using the apparatus (9) is to connect the apparatus (9) to the lighting system of the vehicle (14) so that when the brake pedal of a vehicle is depressed, the low voltage power supply (12) generates a source of low voltage high frequency electrical energy to power the high voltage transformer (21) and in turn the associated neon bulb (20) to augment the vehicle brake lighting system.

Abstract: Abstract:            A method and a press for carrying out the method are proposed for controlling the drive of a hydraulic press for the purpose of forming and/or cutting sheets of metal or the like. In order to propose a novel control of the drive of such a press in which, in particular, use i made of the principal of secondary control, the different movements of the press ram and of the piston/cylinder unit driving the press ram are coordinated with one another,  it  being the case that a pressure network operates in a closed circuit and a maximum system pres-sure is determined by a pressure accumulator. Here, the piston of a piston/cylinder unit is restrained on both sides at as high a pressure level as possible and force is applied to the press ram by performing a selective removal of volumetric flow in one piston/cylinder unit.

Abstract: Les processeurs possédant une structure a instruction unique et données multiples constitue une nouvelle catégorie de processeurs de signaux vidéo intégrés qui convient particulièrement au traitement en temps réel d'images bidimensionnelles. La structure à instruction simple et données multiples est adoptée pour exploiter le haut degré de parallelisme inhérent à de nombreux algorithmes de traitement de signaux vidéo. On a ajouté à ladite structure des éléments qui aident à l'exécution et au séquençage conditionnels qu'il était impossible de réaliser avec les machines à instruction unique des données multiples classiques. Une machine de transfert séparée décharge le traitement de transaction du noyau d'exécution, ce qui permet un équilibrage des ressources d'entrée, de sortie et de calcul. Cela représente un facteur critique de l'optimisation de l'exécution du traitement de signaux vidéo. Ces éléments additionnels couplés avec une structure évolutive permet une exécution au moyen d'un modèle unique de programmation et fondée sur l'application.

Title: Blood extraction flow control calibration system and method
Inventor: PRINCE PAUL R
IPC: G05D7/06
Filed: 1993-05-28
Abstract: A method and system for calibrating and controlling the with-drawal of a fluid, such as blood, from a fluid source, such as a blood vessel, includes a fluid pump (26), a pressure sensor (24), a flow rate sensor, and a microprocessor based flow control subsystem. The flow control subsystem optimizes the flow rate by sensing zero flow rate pressure within the subject, making a plurality of periodic flow path pressure measurements and extrapolating a calibration flow rate curve (I10). A control curve (130) is generated by utilizing the zero-flow rate pressure point ( 100), the slope of the calibration curve ( 110), and an empirically predetermined pressure offset value (150). The blood pump (26) is then operated at a maximum speed that is limited by the flow control curve ( 130) to maximize flow without occlusion or collapse of the blood vessel during blood withdrawal. The method and system of the invention is particularly applicable to automated apheresis system.

Title: Stabilizing agent for beer
Inventor: TANAKA MASANORI
IPC: C12H1/044
Filed: 1995-05-17
Abstract: A stabilizing agent for beer comprising a particular amorphous silica exhibiting a large negative zeta--potential in the pH region of the beer. The amorphous silica is of the-xerogel type and has a specific surface area of from 100 to 600 m2/g, a porous volume of 1 to 2 cc/g, and OH groups in a number of not larger than 7/nm2 on the silica surface, and an aqueous suspension thereof exhibits a pH of from 4 to 6.2 and a zeta-potential of negative polarity, the absolute value thereof being not smaller than 20 mV. When used as a stabilizing agent for beer, the amorphous particulate silica effectively removes the haze since the aqueous suspension thereof exhibits a weakly acidic pH which is close to that of the beer and a large negative zeta-potential, and helps improve froth-holding property and fragrance-retaining property of the beer.
