Patent EP-0389507-A1 (EP)
Inventor: FRITSCH WALTER
IPC: B29C45/13
Filed: 1988-10-29
Abstract: Dans un dispositif de fabrication de pièces moulées composites en plastique, au moins deux mélanges de réaction différents sont injectés en même temps ou l'un après l'autre dans l'empreinte (28, 28', 28'') d'un moule (20, 22) par différents culots (24, 26). Pendant le temps d'injection d'au moins un des mélanges de réaction, l'empreinte est subdivisée en deux ou plusieurs régions mutuellement isolées. Après l'injection d'un mélange de réaction, on enlève le cloisonnement entre les régions de l'empreinte et les mélanges de réaction liquides au moins en partie convergent au niveau du plan de joint. Ce dispositif permet de lier au moins deux matériaux ayant des propriétés différentes par une seule opération. Il est utile pour fabriquer des pare-chocs, des béquets, des parties de la carrosserie et des garnitures intérieures de véhicules à moteur.
Patent EP-0329973-A1 (EP)
Inventor: ENLOE JACK HARRISON
IPC: H01L23/15
Filed: 1989-01-27
Abstract: Dense ceramic sheets suitable for electronic substrates are prepared by hot pressing ceramic green sheets containing ceramic powder and organic binders which leave no undesirable residue upon pyrolysis in the absence of oxygen. Boron nitride sheets made of boron nitride powder in a similar binder are placed on each side of the ceramic green sheet to form a composite. After hot pressing the composite so as to remove the binder and densify the ceramic, the BN layers are removed. 
     Multiple sheets can be made simultaneously by this technique and multilayer ceramic electronic substrates can be produced with internal interconnections between the metal circuits at the various layers by depositing metal circuit patterns on the green sheets such as by screen printing.

Abstract: This invention relates to a continuous perfusion apparatus of a liquid for use in cell culture, hydroponics, breeding, and the like. The perfusion apparatus comprises (1) a container which is horizontally partitioned by an inner lid and whose upper part is open, (2) a hollow cylinder (A) and a small pipe (B) which penetrate through the inner lid to effect communication of the spaces above and below the inner lid with each other and (3) a blast pipe (C) for feeding air into a space below the inner lid. One of the ends of the hollow cylinder (A) is positioned above (a) the inner lid while the other end near (b) the bottom wall of the container. One of the ends of the small pipe (B) is positioned above (c) the inner lid while the other end immediately below (e) the inner lid. Its central part extends downward and is bent by 180° near the bottom wall of the container, but its lowermost part (d) is on a level a little above the lowermost end (b) of the hollow cylinder. After a liquid is fed into the container, air is blown into the space below the inner lid so as to lower an artificial water surface inside this space. When the artificial water surface reaches the lowermost part (d) of the small pipe, the air filled in the space below the inner lid escapes to the upper part of the inner lid through the small pipe (B) and the artificial water surface rises. When this surface reaches one (e) of the ends of the small pipe, lowering of the artificial water surface again takes place. In this manner, the artificial water surface moves up and down repeatedly to cause perfusion of the liquid in the container.

Abstract: Ressort à disque conique utilisé comme diaphragme et comme ressort de rappel de touche de clavier ou similaire. Le ressort à disque conique ci-décrit (D) présente une structure dont la section ondulée forme des ondulations en spirale (P) autour du cercle central (10) d'une feuille d'ébauche à partir de points arbitraires sur sa circonférence. Les ondulations en spirale (P) peuvent commencer en au moins deux points parmi des points équidistants sur la circonférence du cercle central et, de préférence, en des points équidistants à des emplacements impairs. Le ressort à disque conique (D) ci-décrit ne présente pas de stress excentrique et de direction de fonctionnement au moment de la déformation, mais subit une déformation uniforme dans le sens de la circonférence, lorsqu'on l'utilise comme diaphragme. Lorsqu'on l'utilise comme ressort de rappel des touches (43) d'un clavier, la force de pression sur la touche (43) est transmise à toute la région et le ressort subit une déformation douce et présente un fonctionnement de commutation fiable. Il est préférable de supporter et de fixer le ressort conique (D) ci-décrit en appliquant une tension dans un sens centrifuge à la totalité de la circonférence de sa périphérie externe. Cet agencement permet de rendre uniforme la déformation de la totalité du ressort conique.

Title: Two-platen type mold clamper
Inventor: INABA YOSHIHARU
IPC: B29C45/66
Filed: 1989-07-05
Abstract: Two-platen type mould clamper which does not require a tie bar and a rear platen, hence requires a reduced number of components and is easy to maintain and economical. A plurality of ball nuts which are able to rotate relative to a movable platen but not able to move in an axial direction relative to the same are fitted to the movable platen which is disposed so as to be capable of reciprocating relative to a fixed platen. Ball screws are meshed with these ball nuts, respectively. One of the ends of each ball screw is fixed to the fixed platen. With the rotation of a motor, the ball nuts connected to the motor through sprockets and a chain are rotated and the ball nuts and the movable platen move towards the fixed platen. The ball screws extend after mould touch and generate mould clamping force.

Abstract: A broadcaster for granulated product, in particular fertilisers, has a supply container received by a vehicle and possessing a large width transverse to the direction of travel and an outflow orifice in the region of each of its outer ends, a cross-conveyor arranged in the supply container, an agitator above each outflow orifice and a centrifugal disc arranged underneath each of the discharge orifices and intended for distributing the spreading product. To keep the mechanical stress on the fertiliser caused by rotating parts as low as possible, during the spreading work the two agitators are driven continuously, whilst the cross-conveyor has a drive which takes effect as a function of the filling level of the spreading product above the cross-conveyor and which cuts in when the filling level falls below a specific value. <IMAGE>
