Title: Method of forming a hollow prosthesis
Inventor: EATON L DANIEL
IPC: B29D22/00
Filed: 1994-08-01
Abstract: The method of the present invention creates a hollow plastic prosthesis using the following steps. First, a mold of the prosthetic article is created and the mold is injected with room temperature vulcanizable plastic. The mold containing the RTV plastic is maintained at a fixed temperature for a sufficient period of time for the outer most portions of the RTV plastic to form a vulcanized layer in proximity to the inner surface of the mold. The RTV plastic article is then removed from the mold and the remaining unvulcanized plastic is expressed from the interior. The opening is then sealed and the entire article is allowed to completely cure. The prosthetic article thus created is a one piece seamless article conforming substantially to the shape of the mold. The article is hollow and contains no openings communicating with the exterior so that the article retains flexibility and furthermore has the property of being compressible while retaining the ability to return to its original shape once pressure has been moved.

Title: Packaging container and method of forming the same
Inventor: BERGERIOUX CLAUDE
IPC: B65B53/02
Filed: 1994-08-23
Abstract: A packaging container comprises a holding container (11) formed by deforming a multi-layer sheet made of a resin according to a thermoforming method, a lid (13) made of resin and adapted for sealing the holding container (11), and an exterior covering surrounding the exterior of the holding container (11) and made of a non-metallic material having a hardness and a thermal insulating performance higher than those of the holding container (11).  Since no metal is used in the packaging container, the packaging container can be easily crushed after being thrown away, and the collection of the packaging container can be made easier.  Since the holding container (11) and the lid (13) are made of resin and the exterior covering is made of a non-metallic material, food in the packaging container can be directly heated by dielectric heating.  According, the food can be heated to a sufficient temperature within a short time.  Moreover, since the exterior covering has a good thermal insulating performance, the packaging container can be held by hand even immediately after being taken out from a vending machine, and the food held therein is prevented from quickly getting cold.

Title: Methods and apparatus for managing objects and processes in a distributed object operating environment
Inventor: SNYDER ALAN
IPC: G06F9/46
Filed: 1996-03-13
Abstract: A variety of methods and apparatus for managing deactivation and deletion of objects and server processes are taught. According to some embodiments of the present invention, a thread of execution termed the reaper thread systematically cycles through a computer process deactivating and/or deleting objects based upon a variety of criteria. One suitable criterion for object deactivation is based upon the amount of time lapsed since a client has requested services of the object. According to the timeout criterion, the reaper thread determines the period of time since the last client requested services from the object, compares this to a timeout value which may be defined by any suitable entity, and proceeds with deactivation and/or deletion accordingly. Object deletion may have a separate criterion or be specifically requested by a client. A deletion flag may be set to indicate that object deletion is requested. When an object has deactivated, the reaper thread further determines if the deletion flag for this object is set, and, if so, further proceeds to perform an object deletion operation. In some embodiments, the reaper thread is further responsible to shutdown the server process under which the reaper thread is executing. As is well known to those skilled in the art of object oriented programming, a thread of execution is essentially a sequential flow of the point of execution through a computer process. One suitable criterion for server process shutdown would be related to the server process activity.

Title: Webbing Take-Up Device
Inventor: HORI SEIJI
IPC: B60R22/28
Filed: 1996-04-17
Abstract: There is provided a webbing take-up device in which a load required to rotate a spool in a webbing drawing direction with reference to a shaft is stabilized in the process of rotating the spool, a stable load can be achieved with small deformation, and miniaturization can be achieved.          In an ordinary state, an EA plate keeps its original shape, and the shaft and spool are rotated together with each other.  When the shaft is prevented from being rotated in the webbing drawing direction in vehicle sudden deceleration, the EA plate is plastically deformed by a webbing drawing force, and the EA plate is pushed in an internal-angle portion of the spool with rotation of the spool in the webbing drawing direction with reference to the shaft.  The EA plate is bent by a U-shaped portion and then wound around the outer periphery of the shaft.  The other end portion of the EA plate is pushed into the internal-angle portion at a winding start end portion of the EA plate around the shaft to prevent the subsequential rotation of the spool in the webbing drawing direction with reference to the shaft.  Thus, when the webbing is prevented from being drawn, the webbing is drawn by a predetermined length, and energy absorption can be achieved.

Title: Boundary-spline-wavelet compression for video images
Inventor: YUEN PAK-KAY
IPC: H04N7/26
Filed: 1995-01-13
Abstract: A method and apparatus for performing video image compression and decompression are disclosed. The video image compression is performed using boundary-split-wavelet decomposition, in which the wavelets applied to sample locations at the boundaries of image intervals are different from those applied to sample locations within the intervals. The decomposition is performed first for horizontal rows of the image data, and then in a vertical direction upon the results of the first decomposition. Quantization serves to locally round off the higher frequency components of the decomposition, and the decomposition is repeated until the desired compression ratio is obtained. Lossless compression may then be applied to the decomposed image data, and the compressed image is transmitted or stored, depending upon the application. Decompression is effected by lossless decompression of the received data, followed by reconstruction of the image using boundaly-spline-wavelets, repeated as necessary to fully reconstruct the image. The reconstructed image can then be displayed on a conventional video display.

Filed: 1995-01-18
Abstract: An apparatus  for  packing fowl which includes first (12)  and  second (14) workstations.  The first workstation is provided  to receive the  product to be packaged.  A pusher mechanism  (18) pushes the product from the first station between spaced  plates  (30, 32)  into a plastic bag and then  through the gates of a clipper mechanism.   Advancement is slightly retarded by means of a blocking mechanism (34) to thereby insure  that the product is tightly retained within the flexible plastic bag. The bag and product are thereby moved to the second station at which time a holding bar preliminary closes the bag.  Thence, gates close and gather the neck of the  bag  and a metal clip is advanced  by  means of a  punch in a clip channel defined by the closed gates. The clip is thereby fastened about the neck of the closed  plastic  bag  and the excess tail of the bag is cut by means of a knife.  Trap  doors then release the packaged product  onto  a conveyor  belt, a new bag is positioned  on  the spaced, guide plates, and the apparatus is ready to recycle.

Filed: 1995-07-05
Abstract: A fumigant, comprising cyanogen (C2N2) (as herein defined), provides a viable alternative to conventional fumigants such as methyl bromide, phosphine and carbonyl sulphide. Experiments have shown that cyanogen (C2N2) can be used as such a fumigant, in the control of a range of biota, including insects, mites, nematodes, fungi and their spores, viruses, spiders, bacteria, moulds and rodents. It is also suitable for use on a variety of commodities, including grain, seeds, meats, fruit, vegetables, timber, plants, cut flowers and soil.  It is shown that an efficacious concentration of cyanogen (C2N2) as a fumigant leaves a very low residue and can be readily flushed from commodities. In particular, it has been observed that a mixture of cyanogen (C2N2) and carbon dioxide have a synergistic effect, when applied to various biota. Throughout the specification, it should be noted that the term "cyanogen" is defined as the gas (at STP) cyanogen, C2N2, essentially free from hydrogen cyanide and other cyanogenic compounds (that is, compounds that give rise to hydrogen cyanide). Cyanogen, which has also been termed dicyan and oxalonitrile, as a fumigant, may be shown as (CN)2, C2N2 or NC-CN.
