Patent CA-2225287-C (CA)
Title: Multi-layer injection molding apparatus having three position valve member
Inventor: ZHUANG HELEN
IPC: B29C45/16
Filed: 1997-12-18
Granted: 2005-09-13
Abstract: Valve gated injection molding apparatus having three position valve member actuating mechanism for multi-layer molding. A first melt passage extends to the gate through an annular channel in a heated nozzle, while a second melt passage extends around an elongated valve member in a central melt channel. A rack member engaging the rear end of the valve member is driven by a pinion member connected to a front piston in a front cylinder. A rear piston in a shorter rear cylinder aligned with the front cylinder has a stem extending forwardly into the front cylinder. First, air pressure applied behind the rear piston retracts the valve member from a first closed position to a second partially open position wherein melt flows only through the annular channel. Then, air pressure applied behind the front piston retracts the valve member to a third fully open position wherein melt flows simultaneously through both melt channels to provide the three layers. When the cavity is nearly full, air pressure is released behind and applied in front of the front piston to return the valve member to the second position until the cavity is full. Air pressure is then released behind the third piston to advance the valve member to the first closed position in which its front end is seated in the gate for ejection.

Abstract: A delamination problem in fabric laminates made of a fabric laminated to a n on- porous, hydrophilic organic polymer film, such as a breathable polyurethane film, was found to be caused by the hydrophilic nature of the polymer. A particular adhesive pattern was devised to overcome the delamination problem . More specifically, a wash-durable fabric laminate of a continuous, non-porou s hydrophilic polymer, e.g., a breathable polyurethane, layer and a fabric lay er were bonded together by a discontinuous, but interconnected pattern of an adhesive layer. The fabric laminate is water-vapor-permeable, air-impermeabl e and liquid water impermeable.

Abstract: A multipole ion guide is configured to improve the transmission efficiency of ions which traverse the length of one guide (7) and enter either another multipole ion guide such as a quadrupole mass analyser (14) or a three-dimensional ion trap (64). The ion transfer multipole ion guide radial dimensions are reduced such that the pole assembly (30) and an appropriately shaped exit lens (31) can be positioned within a portion of the internal space defined by the larger radius second multipole ion guide poles (43). Ions exiting the first ion guide of reduced size find themselves inside the second ion guide close to the centerline (41).  In this manner, ions can be efficiently transferred from one ion guide to another, even for those ions with low kinetic energies. In a second embodiment of the invention, the exit region of a multipole ion guide (50) is configured such that the multipole ion guide poles can be extended into a counterbore (65) of a three-dimensional ion trap end cap electrode (64). With this configuration, ions (including those with low kinetic energies) can be transferred into a three-dimensional ion trap with increased trapping efficiency.

Granted: 2004-08-31
Abstract: The invention is directed to a method for adapting injection molding machines utilizing horizontally opening and closing molds and their opening and closing mechanisms to vertically opening and closing molds and their opening and closing mechanisms and vice versa. An injection molding machine might, for example, be utilized to inject hot synthetic resin substantially horizontally into a cavity between horizontally opening and closing molds associated with horizontally opening and closing mechanisms. This horizontal mold and its opening and closing mechanism is removed relative to the injection molding machine and substituted therefor is a vertically opening and closing mold and its associated vertically opening and closing mechanisms.  The hot plastic material from the horizontal injection molding machine is initially constrained in movement horizontally but subsequently vertically into the cavity of the vertically opening mold. This allows molds to be utilized with presses which might otherwise heretofore been structurally and functionally incompatible.

Title: Ligand-mediated immunofunctional hormone binding protein assay method
Inventor: CARLSSON LENA MARIANA SUSANN
IPC: A61K38/30
Filed: 1991-11-19
Granted: 2008-01-08
Abstract: A ligand-mediated immunofunctional assay (LIFA) method for detecting the presence and the concentration of polypeptide hormone binding proteins which comprises capturing the binding protein with a solid phase bound first antibody, saturating the bound hormone binding protein with the ligand polypeptide hormone, and detecting the bound ligand polypeptide hormone with a detectably labeled second antibody specific for the ligand polypeptide hormone. In the absence of added saturating polypeptide hormone, the LIFA measures the amount of hormone binding protein bound to the endogenous ligand polypeptide hormone. A growth hormone binding protein assay illustrates the method of the present invention. LIFA  assay results indicate that increased binding protein substantially increases growth hormone activity. Methods of use and formulations of growth hormone binding protein, growth hormone, insulin-like growth factor-I and insulin-like growth factor binding protein are disclosed.
