Patent CA-2209863-A1 (CA)
Title: Underactuated mechanical finger with return actuation
Inventor: GOSSELIN CLEMENT M
IPC: B25J15/00
Filed: 1997-07-09
Abstract: This invention provides a finger with three phalanges and three degrees of freedom for a flexible and versatile mechanical gripper which uses only a limited number of actuators. The finger is robust, can provide large grasping forces and can perform power grasps as well as pinch grasps. The mechanism used in the finger has an additional mechanism maintaining the last phalanx orthogonal to the palm in order to allow the gripper to perform pinch grasps on objects of different sizes. For purposes of fine control, tactile sensors as well as potentiometers are included in the finger. The mechanical gripper designed using these fingers allows the stable grasping of a wide class of objects while specifying only two coordinates (the force or position for closing the whole finger and the orientation of the finger) for each of the fingers.      The mechanical gripper has three fingers and three phalanges per finger. When performing a grasp, the fingers will progressively envelope the object to be grasped and eventually reach a static equilibrium.      Underactuation between the fingers of the gripper is also possible.

Inventor: ZHANG LISHA
IPC: A61K31/12
Filed: 1997-01-31
Abstract: The present invention relates to methods for the inhibition of the gene product of the neu oncogene, p185neu tyrosine kinase. Over-expression of the neu oncogene leads to chemoresistance. The methods disclosed involve the novel use of emodin in combination with chemotherapeutic drugs to treat carcinoma. Furthermore, emodin surprisingly potentiates the antineoplastic effects of the chemotherapeutic agents. The inventors propose that emodin sensitizes cancer cells such that they become amenable to treatment by chemotherapeutic drugs.

Patent CA-2245850-A1 (CA)
Title: An optical connection
Inventor: HEITMANN WALTER
IPC: G02B6/38
Filed: 1998-08-27
Abstract: The optical connection here described, between fibre optic waveguides and an optical window, in particular for measurement purposes, ensures improved long-term stability and improved measurement precision because of the extreme stability of transmissions. The surface of the optical window is coated with a thin, absorption-free layer of extremely hard material, with the result that its scratch resistance is greatly increased and thus measurement precision is similarly enhanced by the elimination of scratches.  The thickness of the protective layer is such that troublesome reflection losses caused by differences in the refractive indexes have largely been eliminated.  The hardness of the protective layer is greater than that of the material used for the optical window. In addition, its optical thickness is very small in relation to the operating wavelengths that are involved.  A protective layer of corundum is used for optical windows or the like that are of quartz glass.  Oxides, nitrides, borides, and carbides can also be used.  In the case of optical windows or the like that are of multi-component glasses or of plastic, the protective layer is of an absorption-free organic or inorganic material that is of great hardness.  The optical thickness of the protective layer is between 1/1000 and 1/10 of the operating wavelengths.  The layers are applied using ion-supported processes or ion-beam atomizing processes, or MicroPlasma processes.

Abstract: An adhesive coated flexible core (10) is fed to an extruder which extrudes a low density, closed cell foam sheath (14) about the core. The core and sheath composite is then cut into rod-like elements (16) of predetermined length. Each of the rod-like elements is then restrained at a position spaced inwardly from one of its ends, and an orificed plate (20) and an element end are axially pressed together such that the core extends through the orifice (22) in the plate and the foam sheath is compressed. The excess core extending through the plate orifice is then cut, and the pressure between the plate and the element is released, such that the foam sheath returns to its original condition, thereby producing a composite in which the core end is recessed into the foam sheath end. The end of the element is finished by sealing, preferably through the application of a hot brand (30).
