Patent CA-2181997-A1 (CA)
Inventor: MIDDELMAN ERIK
IPC: H05K3/00
Filed: 1995-01-25
Abstract: The invention relates to a method of making a composite laminate comprising the steps of providing unidirectionally oriented parallel fibres (UD filaments) (3) with a resin matrix to form a composite UD layer and laminating a plurality of UD layers to form a UD crossply laminate (18). In the method of the invention, the UD filaments are impregnated with a melt of a resin which in the uncured form solidifies below a certain temperature (Tm). Thereupon the UD filaments-containing resin is cooled to a temperature below Tm to produce said composite UD layer. The produced composite UD layer is irreversibly cured before or after lamination. Notably latent curing resins are suitable. The impregnation is preferably conducted by coating a process belt (8) with solid resin (6), laying the UD filaments onto the resin, and heating the resin so as to form the resin melt. The heating of the resin is preferably conducted by means of IR irradiation (11).

Title: Barrier package
Inventor: AMBLER DAVID M
IPC: B65D65/40
Filed: 1995-02-27
Abstract: A barrier package for the storage of lens wafers used in fabricating laminated lenses comprises a package adapted to be sealed to enclose therein a lens wafer and formed of a multilayer material, including a metallic layer, of low moisture transmission rate, so that conditions of humidity inside the sealed package are substantially isolated from humidity conditions external of the package. Lens wafers so stored exhibit minimum distortions to interface curvature. Instead of or in addition to being stored in a barrier package, the lens wafers can also be coated with a moisture barrier coating to achieve isolation from external humidity fluctuations. The moisture equilibrated precision lens wafers are suitable for use in optical devices.

IPC: C05F17/90
Filed: 1996-10-28
Abstract: The object of the invention is a logistic method for transporting and handling materials in a tunnel composting plant, as well as the plant itself. The materials for tunnel composting brought to the plant are unloaded into intermediate collection points (4.1, 4.2, 4.3) and compostable material is treated from the materials brought also according to the current recipe. The composting materials are transferred to the composting tunnel (3) that is free at the time,and after composting the composted material is transferred from the composting tunnel (3) to a heap of finished material at its own collection point(4.4). Composted material is transported from the heap of finished material to the desired point of use. According to the invention, essentially all of the handling of all the materials at the plant is carried out using a wheeled loader(8), equipped with a mixing and crushing bucket (8.1).

Abstract: La réactivité entre un alloantigène et un anti-alloantigène révèle une réactivité immunologique entre deux échantillons biologiques de la même espèce. La réactivité entre un xénoantigène et un anti-xénoantigène révèle une réactivité immunologique entre deux échantillons biologiques d'espèces différentes. Dans de nombreux cas, les deux réactions révèlent un rejet induit par les anticorps. On peut utiliser des anti-anticorps pour réduire la réactivité croisée dans de nombreux cas de figure du type transplantation, soit dans une espèce similaire soit entre des espèces différentes. On prépare ces anti-anticorps dirigés contre les anticorps responsables du rejet induit par les anticorps. On peut utiliser ces anti-anticorps in vivo ou in vitro pour former un complexe avec les anticorps et réduire ou éliminer ainsi la réactivité entre un alloantigène et un anti-alloantigène, ou la réactivité entre un xénoantigène et un anti-xénoantigène entre deux combinaisons quelconques d'espèce. On peut également utiliser ces anticorps pour cibler et éliminer les lymphocytes B qui produisent des anticorps anti-xénogéniques.

Abstract: A tube connector assembly, preferably for medical use, is provided having a key component and a lid lock component to provide fluid communication between a fluid source and a destination such as a patient. The lid lock component includes a removably lockable lid. The lid is held closed in a locked position by stops located on at least one flexible arm integrally formed and selectively displaceable in the lid lock component. The lid is forced open by a longitudinal key within the key component. The key spreads the flexible arms so that the formerly locked lid is capable of passing through an opening created between the flexible arms to clear the stops. The lid is converted into a position parallel to the length of the lid lock component to provide fluid communication between tubing connected to the lid lock component. The connector assembly can be used for dialysis and the like.

Title: Food molding apparatus and method of forming food products
Inventor: LONDON EUGENE JACK
IPC: A21C11/18
Filed: 1997-05-02
Abstract: The invention provides a molding apparatus and process of molding formable materials which comprises at least one supply manifold for receiving a formable material and plungers or pistons for applying pressure to the formable material within the manifold. A mold plate including at least one mold cavity is driven between fill and discharge positions, with the at least one mold cavity selectively exposed to the supply manifold when in the fill position. A clamp member is positioned adjacent the mold plate when in the fill position, and pressure is applied on the clamp member to clamp the mold plate against the supply manifold. The clamp member and associated structure apply pressure to the clamp member compensating for deflection of these structural members which maintains the moldplate in firm clamping relation relative to the supply manifold. The arrangementeliminates the need to provide the clamp plate with a thick cross section or heavy mass which would accommodate forces normally encountered during filling of the mold cavities. In this manner a mold plate having a relatively thin section, and a clamp member also of relatively thin section may be utilized, to allow a machinehaving significantly increased width to be realized. The significantly increasedwidth of the machine will correspondingly increase capacity, and also allows compatibility with other processing equipment. A mold plate knife assembly is used to cut the formable material at a position adjacent the mold cavities subsequent to filling to facilitate formation of precise portions of the formable material, and also functions to seal off the supply manifold prior to movement of the mold plate toprovide distinct-advantages.

Abstract: Des premier et second systèmes de surveillance de lits (20, 220) peuvent être utilisés, respectivement, à domicile ou dans un établissement de soins de santé et détectent de manière fiable une tentative de départ d'un lit ou autre par une personne surveillée avant que les pieds de la personne surveillée ne touchent le sol. Les deux systèmes de surveillance créent un champ de signaux radioélectriques ou neutralisent les signaux cernant un volume désigné se trouvant à proximité du lit, et génèrent un signal d'alarme chaque fois qu'un bracelet de cheville (44) ou autre dispositif porté par la personne surveillée se déplace en dehors du volume surveillé. Le signal d'alarme peut être généré soit au niveau du lit, soit au niveau d'un point éloigné, et l'alarme peut soit retentir au niveau du point éloigné, au niveau du lit, soit être même transmise à un poste d'infirmière ou autre. Un système de surveillance domicile/zone (420) est également conçu et génère un signal d'alarme chaque fois que le signal provenant d'un émetteur du bracelet (44) porté par l'utilisateur tombe en dessous d'un niveau de seuil indiquant que l'utilisateur s'est déplacé au-delà d'une zone de "sécurité". La personne soignante peut facilement commuter le dispositif de la fonction "DOMICILE" à la fonction "ZONE" et peut régler l'unité de commande de façon à avoir plusieurs plages dans la même fonction, ce qui permet de modifier l'étendue de la zone de "sécurité". De préférence, le système de surveillance domicile/zone (420) comporte un système intégré de surveillance de lit afin de pouvoir effectuer une surveillance en continu si l'état de la personne surveillée se détériore ou si elle commence à s'éloigner du lit.
