Title: Separation of heavy metals from waste water of the titanium dioxide industry
Inventor: SCHINKITZ DIETER
IPC: C02F9/00
Filed: 1992-10-01
Abstract: For economical and assured separation of chromium, vanadium and titanium ions from acidic waste waters, which accrue in great quantities in preparation of titanium dioxide, the pH is first raised to around a value of 3 by addition of a calcium and magnesium compound, preferably through addition of dolomite brick powder. Directly thereafter, the pH is fine tuned into the range of 4.3 to 4.7 through addition of calcium hydroxide and/or sodium hydroxide, and the hydroxides are separated with the aid of a flocculating agent. Since iron ions and calcium ions remain mainly dissolved in the waste water through such selective precipitation, only a relatively small volume of slush has to be disposed of.
Patent CA-2085939-A1 (CA)
Title: Blood sampling device
Inventor: ISHIBASHI HIROMU
IPC: A61B5/15
Filed: 1992-12-21
Abstract: A simple low cost blood sampling device provides a vacuum chamber, a skin suction portion and a piercing and cutting means. The device is sufficiently simple and painless to facilitate its use by the person from whom the blood sample is required, even in the case of a child. The piercing needle is located within the vacuum chamber such that upon the application of vacuum the skin is drawn upwardly against the piercing needle, and being in an engorged condition, due to the suction effect, readily yields the desired blood sample. The local stretching sensation of the skin tends to mask the pain that the penetration of the needle might otherwise produce.

Abstract: Entretoise d'écartement imperméable aux gaz et isolante (15) utilisée pour les vitres isolées de portes et fenêtres permettant de séparer avec précision deux ou plusieurs panneaux transparents de verre ou de plastique (13, 14), que l'on fixe en place de façon hermétique pour empêcher l'entrée ou la sortie d'humidité, et qui peut contenir divers gaz inertes ou de l'air entre lesdits panneaux adjacents, utilisée pour les vitres isolées de portes et fenêtres. L'entretoise (15) est fabriquée avec un matériau organique isolant tel que le carton ou le plastique ayant une rigidité appropriée, sur lequel on applique une couche ou strate de matériaux de barrage aux vapeurs d'humidité ou aux gaz (22, 24, 25), de manière à former un âme isolante composite que l'on peut mouler en structures tubulaires pour former des unités d'entretoise individuelles. De telles structures d'écartement peuvent avoir une conductivité thermique extrêment basse, de manière à ne pas constituer un barrage thermique entre le panneaux séparés, diminuant par là, voire éliminant ainsi le problème du givrage des bords de fenêtres et/ou de la formation de points de condensation périphériques, commme cela se produit lorsqu'on utilise des dispositifs d'écartement métalliques. L'entretoise d'écartement en forme de tube creux peut servir à contenir des matériaux déshydratants (19) pour absorber l'humidité et les vapeurs organiques qui circulent ou sont présentes dans la cavité de fenêtre creuse et qui peuvent s'introduire lorsqu'on met en place l'entretoise. Le(s) matériau(x) pour l'entretoise d'écartement isolante et améliorée peut(peuvent) avoir une forme de ruban plat et flexible, d'une longueur continue de préférence ou à section rigide préformée, comme cela est le cas actuellement, de manière à bénéficier de l'avantage économique de pouvoir fabriquer des entretoises d'écartement de tailles diverses sans faire de pertes par coupe comme cela est le cas lorsque les ensembles d'entretoise d'écartement sont découpés dans des lorsque les ensembles d'entretoise d'écartement sont découpés dans des longueurs standard de profil creux préformé et rigide. Il est également envisagé toutefois de fabriquer une entretoise d'écartementunique de longueurs prédéterminées. Les entretoises de longueurs standard et rigides seraient alors aisément coupées à angles droits ou mitrées ou jointes par des joints insérés por former des entretoises d'écartement isolantes. On peut également aisément inclure un film de protection contre la détérioration par l'ultraviolet dans la formule de revêtements ou celle de l'entretoise d'écartement.
