Inventor: DELMAS FRANCOIS
IPC: C01B7/14
Filed: 1993-06-25
Abstract: The invention relates to a process for the purification of an aqueous alkali metal chloride solution containing iodine in which oxidation is carried out to molecular iodine and then it is adsorbed on active charcoal.

Title: Method and apparatus for treating an ophthalmic lens mold
Inventor: ADAMS JONATHAN P
IPC: B29C39/22
Filed: 1993-12-17
Abstract: An apparatus and method for directing accelerated electrons to at least part of one surface of one ophthalmic mold piece prior to filling with monomer and lens polymerization. In particular it has been found that generation of the ionized oxygen by means of a corona treatment electrode sufficiently increases the adherence of the polymer to the mold piece so treated. Tn the preferred embodiment, the flange around the convex, male piece of the lens mold is corona treated so that when the mold pieces are separated after lens polymerization, the flashing of excess polymerized material surrounding the lens cavity adheres to that male, convex piece flange while the lens is removed with the female, concave piece.

Title: Discharge and transfer system for apparatus for gelatin coating tablets
Inventor: BERTA NORBERT I
IPC: A23G7/00
Filed: 1994-01-11
Abstract: Apparatus and method for coating products with two colors including a first coating section, a second coating section and a side to side transfer device for transferring products from the first to the second sections. The transfer device includes a pair of plate grippers each having a movable upper jaw and a movable lower jaw. The upper and lower jaws are each adapted to receive and retain a product carrier plate.      The transfer device includes a cam follower that precisely closes the upper and lower jaws so that carrier plates located in the jaws are positioned in registration with each other in order to clamp product between the plates and to maintain the product clamped in the plates while the grippers are transferred between the first and second conveyor guides. An unloading station includes breaker pins for breaking a seal that may be formed between the coating material applied in the first coating section and the carrier plates. At a discharge station the carrier plates are rotated to cause the product to fall to a collection bin. Clean out bars adapted to be extended through the carrier plates while the plates are in the rotated discharge position cause any product that may have adhered to the plate and any excess coating material on the plate to be removed.

Title: Fibrinogen processing apparatus, method and container
Inventor: COELHO PHILIP H
IPC: B05D1/18
Filed: 1994-01-18
Abstract: ABSTRACT OF THE DISCLOSURE An instrumentality for promulgating the cryoprecipitation of fibrinogen from a blood product. The instrumentality contemplates a container for the blood product, an apparatus for creating the fibrinogen within the container and a method of manipulating the container within the apparatus and subsequently after fibrinogen has been formed. The apparatus includes a receiver within which the container is supported, a motion transfer device for the receiver to impart motion to the container while simultaneously subjecting the container to a temperature differential to cause heat transfer. The motion imparted to the container results in a thin coating of the blood product being disposed on an interior surface of the container which, in turn, is exposed to a heat transfer fluid through the wall of the container. Successive coatings placed on an interior of the container are timed such that each coating is placed on a previous coating that has changed phase. Flexure of the container after the contents of the container have been frozen can occur by providing a vacuum within the container causing an implosion of frozen material.Subsequent phase change back to a liquid and then a second freeze/thaw followed by centrifugation causes a cryo-fraction to be precipitated therefrom. The container within which the blood product is housed includes an opening for admission of the blood product therewithin, an outlet for extraction of fibrinogen and access to a source which can provide a pressure differential vis a vis the interior and exterior of the container. Information of the temperature profile within the container may also be provided.

Title: Detachable Embolic Coil Assembly
Inventor: PALERMO THOMAS J
IPC: A61L31/04
Filed: 1993-09-03
Abstract: This invention is a surgical instrument and specifically is a device for delivering embolic coils to a selected site within the vasculature of the human body via use of a catheter.  In particular, the device involves an embolic coil having a radially enlarged member attached to one end, which coil is released-by forcing the radially enlarged member axially through a distendible aperture situated on the distal end of a pusher assembly.  Alternatively, the embolic coils may be mounted on a guidewire  and a pusher sheath within the catheter lumen used to push through the coils through the end of the catheter lumen.  The catheter has a constricted distal tip or other means of frictionally controlling the release of embolic coils.  Additionally (or alternatively), the guidewire may engage the embolic coils from their interior to allow precise placement of the coils.

Abstract: Abstract of the Disclosure A concrete tile of integral, one-piece construction has left side and right side portions of different coloring which extends through the entire thickness of the relatively thin, generally planar tile.  An upper surface of the tile has a groove therein which separates the differently colored left side and right side portions.  The left and right side portions have different lengths, providing the tile with a stepped front edge.  A method of making the tile dispenses wet concrete having two different colors into a partitioned pug box for disposition onto opposite sides of a pallet, so that the two different colors reside on opposite sides of the pallet in side-by-side relation.  The wet concrete is metered and compressed by a roller and shaped by a slipper to provide the concrete tile with a desired cross-sectional shape, following which the concrete is then chopped by a knife assembly to form the individual tiles with desired edge configurations.  The concrete is cured and then removed from the pallets to form the completed tiles.  The method may be incorporated into a continuous process in which a succession of the pallets are passed by a conveyor beneath a making head assembly containing the partitioned pug box and the roller and slipper and then beneath a knife assembly to form a succession of the concrete tiles.

Title: High Torque Double Gimbal Control Moment Gyro
Inventor: ROSEN HAROLD A
IPC: B64G1/28
Filed: 1994-07-27
Abstract: A  system  and  related  method  is  provided  for  rapidly repointing spacecraft through the application of a high torque, of a gyroscope in which braking means  (20,  22) provided on a gimbal (16, 18) is actuated simultaneously with the actuation of the  torque  motor  (24,  26)  to  achieve  amplification  of  the control moment imparted to the gyroscope (10).  Because only one brake  (20,  22) may be actuated at a time in a double gimbal gyroscope system having a single spin wheel (12), actuation of the brake  (20,  22)  for each of  the  two axes  is  sequential. However  in a system having redundant torque motors  (24,  26), re-pointing  of  the  spacecraft  may  be  achieved  using  the simultaneous  braking  and  torque  application  method  of  the present  invention  without  increasing  the  repointing  time  by applying torque to a gimbal (16) rotating about one axis of the first spin wheel (12) at the same time that torque is applied to a  gimbal  (18)  rotating  around  the  orthogonal  axis  of  the redundant spin wheel (12).
