Inventor: FRIESEN HENRY
IPC: B60D1/36
Filed: 1994-05-31
Granted: 1998-12-22
Abstract: An implement includes a clevis assembly connected to the forward end of the implement hitch for limited fore-and-aft movement to permit holes in the clevis and of a tractor drawbar to become aligned for receiving a hitch pin, a latch then being operable to prevent further fore-and-aft movement of the clevis.  First and second parallel legs of the clevis are provided with holes in which are received first and second bushing portions respectively of first and second jaws.  The bushing portion of the first jaw is threaded and the hitch pin has a threaded end received therein, the pin being operable to move the first jaw towards the second jaw so that the jaws may tightly clamp a drawbar located therebetween.

Title: Ophthalmic pachymeter and method of making ophthalmic determinations
Inventor: SNOOK RICHARD K
IPC: A61B3/14
Filed: 1994-07-05
Granted: 2006-05-16
Abstract: An ophthalmic pachymeter which is highly effective in aiding in the determination of thickness and the optical density of the cornea of an eye an a real-time basis. The pachymeter therefore lends itself to effective employment in aiding in radial keratotomy and other surgical procedures With respect to the eye. The ophthalmic pachymeter of the invention has three major subsystems which include a television camera, a multiple slit projector and an associated processing and display system. In a broad form, the invention comprises illuminating a selected portion of the cornea, moving a slit across the cornea and generating Tyndall image ray paths for enabling, analysis of the optical density of the cornea and the thickness of the cornea. This is accomplished through a series of digitally-encoded television images of the optical section of the cornea produced by a multiple slit projector and which images are then subjected to digital analysis. A locus of each of the significant elements of the reflected image of the anterior portion of the eye is defined. In this way, the optical character of the cornea/air interface is compared with the corrected reflectance of the stroma and the endothelium, in order to determine relative transparency. A density map may be constructed in parallel slices far display as a three-dimensional plot of the frontal surface shape of the cornea and for defining and displaying the local thickness, the posterior surface contour, and the optical density of the cornea.

Title: Transgenic animal models for alzheimer's disease
Inventor: WADSWORTH SAMUEL
IPC: G01N33/48
Filed: 1992-12-29
Granted: 2007-04-17
Abstract: The construction of transgenic animal models for testing potential treatments for Alzheimer's disease are described. The models are characterized by a greater similarity to the conditions existing in naturally occurring Alzheimer's disease, based on expression of all three forms of the .beta.-amyloid precursor protein (APP), APP695, APP751, and APP770, as well as various point mutations based on naturally occurring mutations, such as the London and Indiana familial Alzheimer's disease (FAD) mutations at amino acid 717, and predicted mutations in the APP gene. The APP gene constructs are prepared using the naturally occurring promoter, as well as inducible promoters such as the mouse metallothionine promoter, which can be regulated by addition of heavy metals such as zinc to the animal's water or diet, and promoters such as the rat neuron specific enolase promoter, human .beta. actin gene promoter, human platelet derived growth factor B (PDGF-B) chain gene promoter, rat sodium channel gene promoter, mouse myelin basic protein gene promoter, human copper-zinc superoxide dismutase gene promoter and mammalian POU-domain regulatory gene promoter. The constructs are introduced into animal embryos using standard techniques such as microinjection. Animal cells can be isolated from the transgenic animals or prepared using the same contructs with standard techniques such as lipofection or electroporation. The transgenic animals, or animal cells, are used to screen for compounds altering the pathological course of Alzheimer's disease as measured by their effect on the amount and histopathology of APP and .beta.-amyloid peptide in the animals, as well as by behavioral alterations.

Title: Therapy and imaging probe and therapeutic treatment apparatus utilizing it
Inventor: DORY JACQUES
IPC: A61B8/12
Filed: 1994-07-26
Granted: 2002-11-19
Abstract: The therapy and imaging probe of the invention comprises a probe body (20') of an elongate shape defining a general axis (X-X), one imaging transducer (40') for transmitting imaging waves, and one therapy transducer (30') for transmitting therapy waves.     The imaging transducer is mounted on first support means providing translational movement of the imaging transducer within the probe, parallel to the general axis (X-X) of the probe, between a withdrawn position and an extended position. The therapy transducer is mounted on second support means providing rotation of the therapy transducer within the probe, about an axis of rotation (X1-X1) parallel to the general axis (X-X) of the probe but offset with respect to the imaging transducer, to allow rotation of the therapy transducer between a withdrawn position and a treatment position. In the withdrawn or non-active position of the therapy transducer, the imaging transducer may be brought by translational movement to its extended position to occupy the place occupied by the therapy transducer in its treatment position. Thus, the imaging transducer may form an image of a region for treatment by the therapy transducer. In the treatment position of the therapy transducer, the imaging transducer is at its withdrawn position, The therapy transducer, during the transmission of therapy waves, directly transmits the therapy waves in a direction substantially identical to the direction in which the imaging transducer transmits the imaging waves when imaging waves are being transmitted.

Abstract: L'invention concerne les antennes d'émission des lochs Doppler et des courantomètres. Elle consiste à répartir les transducteurs (701) d'une telle antenne sur une base plane circulaire. Les polarités, les phases et la séquence d'alimentation de ces transducteurs avec deux fréquences distinctes F1 et F2 permettent d'obtenir quatre lobes d'émission inclinés de 30 DEG  sur l'avant, sur l'arrière, à babord et à tribord. Une sommation adéquate des signaux de réception permet de définir deux lobes de réception avant/arrière et babord/tribord dans lesquels les échos sont distingués par la fréquence. Elle permet de déterminer la vitesse du bâtiment porteur indépendamment de la vitesse de propagation du son dans l'eau. En outre la base d'émission plane est sensiblement plus petite qu'une base ordinaire comprenant quatre groupes de transducteurs inclinés.

Abstract: Multiple branch peptide constructions formed from peptides derived from the V3 loop of gp120 protein of HIV-1, and including the consensus sequence GPGR preceded by 0 to 4 amino acids and succeeded by 2 to 4 amino acids, preferably not including I in the 3 amino acids immediately preceding GPGR and most preferably GPGRAF, show increased receptor affinity and prevent cell-to-cell fusion. They have a direct virostatic effect. Because they present the same peptide sequence several times, these MBPCs are able to neutralize in vitro the different steps of virus envelope/cell membrane fusion, and infected cell membrane/uninfected cell membrane fusion of several strains of HIV-1 and HIV-2. Notably, they are effective in blockading both CD4 receptors on lymphocytes and macrophages and GalCer receptors on colon epithelial cells. These results open a potential use in treatment of HIV-1 and HIV-2 infection.
