Patent CA-2185617-A1 (CA)
Inventor: AMSTUTZ HANSPETER
IPC: C07K16/00
Filed: 1996-09-16
Abstract: High-titer immunoglobulin preparations are produced by carrying out the following steps in succession: fractionating blood plasma from a plasma pool, whereby at least one industrially usable fraction substantially containingpolyclonal immunoglobulin G is separated, at least one residual fraction being obtained; preparing a protein solution from the protein components contained in the residual fraction obtained in the previous step or in subfractions thereof; and subjecting the resulting protein solution at least once to affinity chromatography with immobilized ligands of at least one ligand type, the specific plasma proteins being bound to the ligands, and removing the bound plasma proteins, which are converted as active components into a high-titer immunoglobulin preparation. The immunoglobulins obtained can be processed into an IV well-tolerated, storage-stable product. The method leading to a valuable immunoglobulin preparation makes use of human plasma fractions which have hitherto been rejected in conventional industrial plasma fractionation methods.

Abstract: A processor of a cellular modem monitors for the presence of a residual echo signal during a full-duplex portion of a training sequence. In particular, the processor monitors an equalizer error signal during a full-duplex training phase that follows the half-duplex training phase for the echo canceler. If the processor detects a level of the error signal greater than a predefined threshold, the processor presumes the increase in the error signal is due to the presence of a residual echo signal and performs a predefined adjustment of the taps of the  corresponding echo canceler of the cellular modem.
Patent CA-2188767-A1 (CA)

IPC: F16K27/02
Filed: 1994-12-02
Abstract: La présente invention concerne un assemblage de vanne-papillon en matière plastique à utiliser dans un système de canalisation en plastique. Le corps de vanne est en matériau thermoplastique, le siège de vanne ayant un noyau dur en matière phénolique ou autre plastique et un couvercle résilient. Le corps de vanne plastique utilise dans sa construction un anneau de blocage pour maintenir la pression sur le siège de vanne, ce qui aide à sceller la fermeture de vanne contre le siège. La pastille de fermeture peut être soit en métal soit en plastique, selon le service envisagé. Elle est retenue dans le corps de vanne par un cône de vanne inférieur fixé dans le corps de vanne de telle manière que ladite pastille de fermeture peut tourner librement sur ledit corps de vanne, et par un cône de vanne supérieur comprenant un anneau de blocage central et soutenu par un logement sur le corps de vanne. Ledit logement a une douille prenant appui contre l'anneau de blocage central et un bouchon tubulaire qui a son siège dans le logement, exerçant ainsi une pression contre la douille et, partant, contre l'anneau de blocage central, de sorte qu'il contribue à la protection anti-échappement. Le bouchon tubulaire est scellé par un joint torique interne d'étanchéité au cône de vanne supérieur. Les cônes de vanne supérieur et inférieur sont scellés au corps à noyau dur du siège de vanne. Le siège de vanne est scellé dans le corps de vanne par une paire de joints toriques d'étanchéité sur les côtés opposés des cônes de vanne. Le cône de vanne supérieur est calé de telle sorte que l'on peut faire tourner la pastille de fermeture à l'aide d'un dispositif à poignée. La vanne a un rayon de fonctionnement de 360~ et comprend une goupille de sécurité pour maintenir la vanne entièrement ouverte, entièrement fermée ou dans diverses positions intermédiaires. La vanne peut être installée dans l'une ou l'autre direction d'un système de canalisation.

Title: Coupon manufacturing machine
Inventor: BEST SCOTT D
IPC: B31D1/02
Filed: 1997-04-17
Abstract: A coupon manufacturing machine assembly (10) for producing a two-sided coupon card (78). The coupon card (78) is fabricated from a continuous sheet of stock (26) wherein the sheet of stock (26) has an adhesive layer (30) and a release film (32) applied to a bottom surface (34). A printing station (12) prints indicia on a top surface (36) of the continuous sheet of stock (12) in two parallel rows. The two parallel rows define a first strip (38) and a second strip (40) of the stock (26). A laminating device (14) applies a clear laminate (46) to the top surface (36) of the stock (26) for viewing the indicia. A cutting device (16) separates the continuous sheet of stock (26) into the first strip (38) and the second strip (40) and an inverting device (18) rotates the second strip (40) 180° relative to the first strip (38). More specifically, the second strip (40) passes through a first turn bar (52), a spacing roller (58), and then through a second turn bar (54) to effectuate the 180° rotation. A striping device (20) removes the release film (32) from the first strip (38) to expose the adhesive layer (30). The adhesive layer (30) of the first strip (38) is moved into a bonded relationship with the release film (32) of the second strip (40). Specifically, a coupling device (22) mates and adheres the adhesive layer (30) of the first strip (38) with the release film (32) of the second strip (40) to form a series of two-sided coupon cards (78) with the indicia printed on both sides thereof.

Title: Multilayer forming fabric
Inventor: BARRETO EDNALDO VILAR
IPC: D03D11/00
Filed: 1995-12-05
Abstract: A triple layer fabric (13), useful in the forming section of a papermakers' machine, is provided. The fabric (13) has a top fabric layer having at least one set of warp yarns (11) interwoven with at least one set of weft yarns (12); a bottom fabric layer having at least two sets of weft yarns (14, 15) forming a top and bottom layer of the bottom fabric layer, and at least one set of warp yarns (16); and at least one binder yarn (18) interweaving and joining the top fabric layer and the bottom fabric layer. The top fabric layer is preferably a plain weave fabric while the bottom fabric layer is preferably a semi-duplex weave. Also, in one preferred embodiment, the weft yarns in the bottom fabric layer (14, 15) are generally stacked, as are the warp and weft yarns of the top and bottom fabric layers. The binder yarns (18) are preferably binder warp yarns, but may be binder wefts. In interweaving the top and bottom fabric layers, the binder yarns (18) engage only the upper weft yarns (14) or the warp yarns (16) of the bottom fabric layer. Thus, the binder yarn (18) is protected by the lower weft yarns (15) of the bottom fabric layer from normal wear and abrasion thereby increasing fabric life.

Abstract: A trim-in-place thermoforming process and system is disclosed. The system includes a mould and a set of co-operating knife assemblies capable of trimming the moulded object across multiple elevational contours while still on the mould. Each knife assembly cuts the moulded object within a limited range of elevational contours because the knives must be kept shallow to discourage them from wobbling out of alignment; however, multiple knife assemblies can be aligned and stacked to provide for cuts that continue across elevational contours. The mould defines multiple swages, each swage being complementary to a specific knife assembly. The knives and swages do not touch, but the clearance between them is minimal, preferably about 4 thousandths of an inch, and plastic stretched across a swage will be sheered when the complementary knife is enveloped in the swage.

Abstract: A swinging/sliding door for vehicles includes at least one door leaf; a support rail fixedly mounted in the vehicle for supporting the door leaf; a carriage longitudinally slidably mounted on the support rail; a pivotable support mechanism, possibly forming an articulated parallelogram, for connecting the door leaf to the carriage; a guide rail fixedly mounted in the vehicle, wherein a guide pin connected to an element of the support mechanism travels in the guide rail and determines the angular position of the support mechanism; a linear drive for effecting the movement of the door leaf or carriage along the support rail, wherein the linear drive acts on an engagement point of the carriage. The engagement element for the carriage is moveable between two positions, wherein one position corresponds to the outwardly swung, open position of the door leaf and the other position corresponds to the inwardly swung, closed position of the door leaf, and wherein the movement of the engagement element from one position to the other position causes a torque to act on a hinge point of the support mechanism on the side of the carriage for effecting the inward and outward movements or for at least substantially reinforcing the movements.
