Title: Injection molding die
Inventor: ABE TOMOKAZU
IPC: B29C45/56
Filed: 1994-06-08
Abstract: ABSTRACT   A die for injection molding for charging molten resin onto a surface material set on the cavity surface is disclosed. The die comprises direction changing means for changing the direction of flow of the molten resin charged-through the gate to directions along the surface of the surface material. The direction changing means may be asubstantially conical direction changing member for changing the direction of flow of the molten resin. Since the direction changing means can change the direction of flow of the molten resin charged into the die, which is completely closed or slightly open, to directions along the surface of the surface material, the molten resin does not strike the surface material. Thus, damage to the surface material in the neighborhood of the gate can be prevented, and the surface material can be protected against the collision with molten resin which is at a high temperature and under a high pressure.

Patent CA-2130780-A1 (CA)
Inventor: SIVILOTTI OLIVO G
IPC: C25C3/04
Filed: 1994-08-24
Abstract: A process for electrolytically producing magnesium metal from MgCl2 dissolved in an electrolyte, by conversion to the product metal and chlorine gas, wherein the MgCl2 content of the electrolyte is replenished by supplying thereto a feed having as components one or more magnesium chloride ammoniates for decomposition by the heat of the electrolyte into MgCl2 and ammonia gas. The feed, which may also include uncombined MgCl2, is delivered to the electrolyte at a location at which the generated ammonia does not come into reactive contact with the chlorine gas. The temperature of the electrolyte as well as its MgCl2 content can be controlled by selection of feed components, relative proportions, and rate of supply. The ammoniate content of the feed can be produced by reaction of ammonia with magnesium chloride hydrates, using the ammonia gas generated by the decomposition.

Title: Immobilized-cell carrageenan bead production and a brewing process utilizing carrageenan bead immobilized yeast cells
Inventor: NEUFELD RONALD J
IPC: C12N11/08
Filed: 1994-10-06
Abstract: A process for immobilizing viable cells in gelled carrageenan beads comprises preparing an aqueous phase that is a mixture of a gellable concentration of un-gelled carrageenan,  in an aqueous suspension of viable cells,  in which the mixture's potassium concentration is low enough that the thermogellation temperature of the carrageenan in the suspension  is  below a  temperature  to which  the viable  cells  are substantially thermosensitive.   This is done at a first processing temperature  that  exceeds  the  thermogellation  temperature  of  the carrageenan  in  that  aqueous  suspension,  but  which  is  below  the temperature to which the cells are substantially thermosensitive.  A mixture of the aqueous phase and a non-reactive food-grade oil phase is then prepared, and subjected to shear by passing it through a static mixer under flow-rate conditions selected to disperse the aqueous phase in the oil phase, such that a resulting emulsion has a selected droplet size  distribution.    Thereafter,  the  temperature  of  the  resulting emulsion is decreased from the first processing temperature, to a second processing temperature which is below the thermogellation temperature of the carrageenan in the suspension.  This results in the formation of polymer gel beads having the immobilized viable cells entrapped therein.
Patent CA-2134123-A1 (CA)
Inventor: SCHNEIDER JAMES
IPC: A61M16/20
Filed: 1993-04-21
Abstract: The invention relates to a respiratory support system (10) which includes a suction catheter device (41), a suction control valve (79), and a ventilator manifold (11). The catheter device (41) includes a proximal end connector (72) having a valve (75) therein which prevents air flow through the catheter (54) until the suction control valve (79) is attached thereto, and a distal end connector (40). The suction control valve (79) includes an actuator (113) which is linearly movable between a first position to a second position. The valve also includes a rotatable valve core (135) which can be rotated by the actuator (113) to a third position to disable its linear movement and to open an ancillary access port. When the actuator (113) is in the first position, atmospheric air can pass through the valve (79) and into the suction pressure source in such a manner that a "hissing" auditory signal is generated, indicative of the presence of suction pressure within the valve (79). The ventilator (11) includes an access port (15) for attachment and detachment of the suction catheter device (41) thereto. The access port (15) has a normally closed valve (16) therein. The placement of the speciallly designed connector (40) of the suctioning device (41) in the access port (15) forces the normally closed valve (16) to an open position.

Title: Wing with a wing grid as the end section
Inventor: LA ROCHE ULRICH
IPC: B64C23/06
Filed: 1994-03-30
Abstract: The wing with the span (b) according to the invention has a main part (1), which has a substantially closed surface with respect to the flow (v) and is provided at its free end with an end section in the form of a wing grid. The wing grid has at least two parallel-staggered winglets (2). Such a wing grid as part of the wing span (b) takes over the intended profile cir-culation at the attachment point to the main part and subdiv-ides said circulation approximately uniformly over the winglets.      Thus, the same lift is produced in the end section with at least two winglets. Thus, for the wing the circulation distri-bution is more complete and the induced resistance is decreased.      An upper or lower limit for the action is obtained, as a function of whether as a result of the fixed wing grid for the entire wing a rectangular circulation distribution is produced or only for the part of the overall span replaced by the wing grid. Thus, for the wing with wing grid there is a correspon-ding reduction of the induced resistance as compared with a conventional wing without a wing grid for the same resulting aspect ratio.
