Title: "shape memory effect surgical needles"
Inventor: BENDEL LEE P
IPC: A61B17/06
Filed: 1992-08-27
Abstract: Abstract of the Disclosure Surgical needles are fabricated from a shape memory alloy.  The alloy has a low temperature state, in which the needle is formable into an elongated shape to pass through an elongated tube, and a high temperature state, in which the needle forms an arc.  The needle is particularly adapted for use in endoscopic surgery.  A needle that has a remembered curved shape is straightened and passed to a surgical site through a cannula.  It is then returned to its curved shape by heating it at the surgical site.  After use, it is withdrawn through the cannula.
Patent CA-2079752-A1 (CA)
Inventor: FUJIHIRA MASAMICHI
IPC: G11B11/00
Filed: 1992-10-02
Abstract: ABSTRACT   A high resolution apparatus for the observation of the properties of a sample material has a photon scanning microscope.  The apparatus detects evanescent light emitted from the sample, the intensity of which depends on the surface structure of the sample and the specific distribution of the optical properties thereof.  The apparatus provides for the detailed detection of the transparency or refractive index of a sample material in a higher resolution than the wavelength of the incident light, which is irradiated onto the sample material that is applied onto the top surface of an optical prism.  The apparatus includes means for maintaining an optical fiber tip, or other means for detecting a positioning signal, at a preselected distance from the sample. Furthermore, the apparatus provides for the detection of fluorescence of the sample.

Title: Electrical, telescopic jack
Inventor: MAGGIORI ENZO
IPC: B66F3/18
Filed: 1992-10-16
Abstract: Abstract Electrical telescopic jack A hoisting device is disclosed, in particular for use in test fields of aircrafts such as helicopters and small airplanes, comprising an   ?, electrically operated assembly provided with coaxial sleeves slidable by being screwed to one another, and a telescopic rod integral with the base of the jack and located at the centre of the sleeve assembly, the last extensible arm of said rod being rotatably connected to the innermost sleeve along which said arm can axially slide.  The outermost sleeve is rotated by a threaded bush, which is itself rotated by a worm screw/crown gear mechanism, and is unscrewed by reaction from the threaded bush as all of the remaining sleeves engaged with one another are prevented from rotating by the telescopic rod.  This is also the case in the following steps for the remaining sleeves without the need of retaining the jack.
Patent CA-2082065-A1 (CA)
Inventor: SITES RICHARD L
IPC: G06F9/44
Filed: 1992-03-04
Abstract: Information about the effects of calling each entry point in a program and information about external calls made by the program are recorded in an image information file. In addition to the addresses of the entry points and call destinations, the information may include any callback parameters and register usage associated with the entry points, and any definite values passed by the calls. When translating two separate but mutual-ly dependent programs that are not easily merged for simul-taneous translation, the image information files for the respec-tive programs permit the programs to be alternately translated with rapid convergence by an iterative method of checked as-sumptions and re-translation. By matching the addresses of the entry points of a first program with the addresses of the exter-nal calls for a second program, and by matching the addresses of the external calls in the first program with the addresses of the program entry points in the second program, the relevant externall calls and entry points in the image information file for the second program are identified. One program should be retranslated when a preceding retranslation of the other pro-gram changes the information for the matching calls and entry points in such a way that changed information might enable additional instructions to be discovered in the program under consideration for translation.

Title: Transgenic non-human mammal displaying the amyloid-forming pathology of alzheimer's disease
Inventor: CORDELL BARBARA
IPC: C12P21/02
Filed: 1991-06-17
Abstract: Cloned recombinant or synthetic DNA sequences related to the pathology of Alzheimer's disease are injected into fertilized mammalian eggs (preferably mice eggs). The injected eggs are implanted in pseudo pregnant females and are grown to term to provide transgenic mice whose cells express proteins related to the pathology of Alzheimer's disease. The injected sequences are constructed having promoter sequences connected so as to express the desired protein in specific tissues of the transgenic mammal (most notably in nerve tissue). The proteins which are preferably ubiquitously expressed include (1) .beta.-amyloid core precursor proteins; and (2) .beta.-amyloid related precursor proteins; and (3) serine protease inhibitor. The transgenic mice provide useful models for studying compounds being tested for their usefulness in treating Alzheimer's disease, and for studying the in vivo interrelationships of these proteins to each other.

Abstract: An improved wash process is provided for a horizontal washer wherein a concentrated detergent solution is applied to a spinning wash load, the load is spun to effect a greater than one gravity force to maintain the clothes load against the basket wall, and the concentrated detergent solution is recirculated through the clothes load for a first period of time. After the first period of time, the detergent solution is diluted somewhat, although the concentration remains abave a normal concentration of 0.06 to .28%. The wash chamber will then be spun to effect less than a one gravity centrifugal force on the fabric such that the fabric will tumble in the wash chamber. The lesser concentrated detergent solution will then be recirculated on to the fabric during a second time period.

Title: Maternity dress for a doll which simulates pregnancy
Inventor: FOGARTY A EDWARD
IPC: A63H3/00
Filed: 1993-03-05
Abstract: ABSTRACT OF THE DISCLOSURE A removable maternity dress (10) for a doll (D) which simulates pregnancy and child delivery and which may be easily adapted to a convention-al doll (D). The invention includes a doll dress (14) preferably made of non-stretchable flexible fabric having a concealed upright front pocket (28) connected thereto. The pocket (28) is sized to receive a baby doll (52) insertable thereinthrough a flapped lower opening at the bottom of the pocket (28). Removal of the baby doll (52) from the pocket (28) downwardly through the lower opening simulates child birth. A front opening (20) in the dress (14) adjacent the pocket (28) coverable by an apron-like fabric sheet (16) may also be provided. A layer of flexible latex (22) or the like connected to and extending across the front opening (20) simulates the appearance of the pregnant mid section of the doll (D). A liquid or gel-filled bladder (36) attached between the front of the dress(14) and the pocket (28) affords a more realistic sensation of touch of the babydoll (52) within the pocket (28). A lenticular screen (42) positioned over an image (50) of the baby doll (52) and having a transducer-like extension (46/48) therefrom affords simulated kicking movement of the baby doll (52) as found on an ultrasound machine (12).

Abstract: Abstract The slide track     interacts with a slide     arranged on a connecting rod    , the slide track being arranged on one of the elements           and the connecting rod being articulated on the other element. As a result, two positions of the elements are determinable with respect to each other, one of them being defined by a catch.      The slide track     has an elongated guide track and a flexible strip     . The catch is designed as a catch recess    , which is located at the one end of the guide track    . The other end of the guide track      forms with the flexible strip      a slit which can be varied in its width by elastic deformation of the strip     , brought about by the slide    .      The guide track is preferably designed as a rising surface     , which together with a lower strip      forms a clasp-shaped central part     . An elongated basic strip runs under the guide track      and also the catch recess     to an outlet from the element. The catch recess is bounded by a first, straight hook, which together with a second, curved hook forms a passage through which the slide     can go onto the basic strip     . The outlet is located in a covering strip of the slide track    , from which the second hook bends off.
