Title: Imaging medium with low refractive index layer
Inventor: BLOOM IRIS B K
IPC: G03C8/24
Filed: 1992-08-06
Abstract: IMAGING MEDIUM WITH LOW REFRACTIVE INDEX LAYER           Abstract of the Disclosure An imaging medium comprises means for providing a light-reflecting layer, an image-receiving layer for receiving image-forming components, a transparent layer superposed over the image-receiving layer such that an image in the image-receiving layer can be viewed through the transparent layer against the light-reflecting layer, and an image enhancement layer disposed between the image-receiving layer and the transparent layer, the image enhancement layer having a refractive index less than that of the transparent layer and the image-receiving layer and not greater than about 1.43.  The image enhancement layer decreases internal reflections within the medium and thereby improves the quality of the image seen.  The imaging medium can be used as the imaging element of a diffusion transfer process film unit.

Title: Sutures Utilizing Shape Memory Alloys
Inventor: PYKA WALTER R
IPC: A61B17/064
Filed: 1991-02-20
Abstract: A suture and a suturing method are set forth for suturing a wound in the tissue of a patient and defined by tissue edges. The suture comprises an alloy member having a first end portion, a second end portion, and a first undeformed shape. It is deformable into a second deformed shape. The member has the property of recovering from its second shape towards its first shape upon the second shape being subjected to specified conditions. The first shape is a suturing loop adapted to draw and hold the tissue edges defining the wound together. The second shape is adapted to allow the member to be drawn through the tissue in position for the loop to form. The method comprises inserting such a member while it is in its second shape into position for it to assume its first suturing loop shape and subjecting it to conditions which cause it to recover towards its first shape.

Title: Logging while drilling apparatus with multiple depth of resistivity investigation
Inventor: SINCLAIR PAUL L
IPC: G01V3/28
Filed: 1992-10-22
Abstract: In an MWD system, a mandrel for connection to the drill bit is set forth which supports shallow, intermediate and deep measuring resistivity systems. By transmitting upwardly and downwardly in alternate fashion, and receiving the transmitted signal at pairs of receiver coils, transmitted signal phase shift and attenuation are measured. A method of measuring is set forth which includes making resistivity measurements close to the drill bit at increasing ranges from the borehole so that formation resistivity prior to fluid invasion is obtained.   Measurements are thus provided of formation resistivity before, during and after fluid invasion.   The method also accommodates formations which have a relative dip angle with respect to the well borehole.

Inventor: MICHAEL J GABRIEL
IPC: A61K38/00
Filed: 1993-01-04
Abstract: An orally administrable therapeutic protein is provided by combining the therapeutic protein with a stabilizing agent in an aqueous solution. The solution is coated onto nonpareils and microencapsulated with a water emulsifiable enteric coating composition. The microcapsules are orally administered. The coating protects the protein as it passes through the stomach. Upon reaching the small intestines, the basic pH of the intestinal juices will dissolve the coating, allowing the protein to be released and induce antigen specific immune response which has the specificity of the native molecule. The stabilizing agent protects the therapeutic protein from denaturation during the encapsulation process. In addition to being immunogenic, when administered orally, encapsulated allergen has a therapeutic effect in the treatment of human allergies.

IPC: C10G1/10
Filed: 1991-08-21
Abstract: A method is described for the recovery of high yields of monomers from waste and scrape polymeric materials with mini-mal amounts of char and tar. The process involves pyrolysis in a circulating fluid bed (CFB). The polymer is heated to a tempera-ture of about 650 °C to about 1000 °C at a rate of more than 500 °C/sec in less than two seconds. Heat is supplied to the CFB by a stream of hot sand heated in a separate combustor. The sand is also used as the circulating fluid bed material of the CFB. The process is essentially devoid of solid carbon char and non-monomeric liquid products.

Title: Method for selecting teeth for the production of dentures or the like
Inventor: LAPOINTE YVES
IPC: A61C19/10
Filed: 1993-07-07
Abstract: A method for determining the size, shape and position of a pair of upper central incisors for the production of dentures comprises the steps of covering the patient's upper gums with a paste, providing a series of representations of different pairs of upper central incisors and positioning different ones of these representations on the paste until a representation of desired size and shape is selected and secured to the paste by way of an adhesive at a chosen location thereon. The paste carrying the selected representation is then removed from the patient's mouth, whereby dentures can be produced on the basis of the positioning of the upper central incisors on the paste roll and on the selected model of upper central incisors, as the latter determine the models of the remaining teeth of the dentures. The method can also be used for the determination of an artificial tooth used for a dental implant, a bridge or a crown. A kit is also proposed which includes a series of templates providing various representations of two-dimensional pairs of upper central incisors, a paste substance to be applied on the patient's gums or on a denture plate, and an adhesive for securing a selected representation to the substance. Also, a method is proposed for determining the vertical dimension of occlusion with a rest position clearance also for the production of dentures, wherein lower central incisors are positioned with respect to the patient's facial characteristics.
