Title: Glycoalkaloids for controlling cellular autophagy
Inventor: CHAM BILL E
IPC: A61P35/00
Filed: 1991-01-18
Abstract: The invention is directed to the control of cellular autophagy, cellular agglutination and the immobilization of motile cells. Such control is useful in, for example, the treatment of cancer, contraception, termination of pregnancy, removal of pathogenic organisms and removal of any abnormal cellular growth (malignant or otherwise); as a diagnostic and analytical tool whereby cell structure can be studied and testing could be undertaken for the presence (and subsequent analysis) of pathogenic and non-pathogenic organisms; and in the manufacture of biochemicals whereby certain cells must be destroyed or otherwise contained. From surface analysis of normal and abnormal cells, specific receptors on abnormal cells which are either not present on normal cells or are only present insignificantly reduced numbers can be identified.  Alkaloids and other pharmaceutically acceptable compounds are preferentially recognised by the abnormal cells, and which bind thereto and subsequently destroy.

Title: Wide field strip-imaging optical system
Inventor: VAUGHAN ARTHUR H
IPC: G02B17/06
Filed: 1992-10-30
Abstract: PATENT APPLICATION           WIDE FIELD STRIP-IMAGING OPTICAL SYSTEM                          ABSTRACT A strip imaging wide angle optical system is provided.  The optical system is provided with a "virtual" material stop to avoid aberrational effects inherent in wide angle optical systems.  The optical system includes a spherical mirror section for receiving light from a 180-degree strip or arc of a target image.  Light received by the spherical mirror section is reflected to a frusto-conical mirror section for subsequent rereflection to a row of optical fibers.  Each optical fiber transmits a portion of the received light to a detector.  The optical system exploits the narrow cone of acceptance associated with optical fibers to substantially eliminate vignetting effects inherent in wide-angle systems.  Further, the optical system exploits the narrow cone of acceptance of the optical fibers to substantially limit spherical aberration.  The optical system is ideally suited for any application wherein a 180-degree strip image need be detected, and is particularly well adapted for use in hostile environments such as in planetary exploration.

Title: Fes method improvements
Inventor: HAUGLAND MORTEN
IPC: A61N1/36
Filed: 1993-06-04
Abstract: ABSTRACT OF THE DISCLOSURE            The motor function of a partially or completely paralyzed muscle is restored by implanting a nerve electrode, e.g. a cuff electrode, for sensing electrical signals from a sensory nerve which innervates a part of the body which is phy-siologically related to the partially or completely paralyzed muscle, stimulating the paralyzed muscle by means of a muscle stimulator, sensing by means of said nerve electrode an electrical signal from the sensory nerve, producing a further control signal for reactivating the muscle stimulator dependent on the electrical signal sensed after the expiration of a predetermined period of time after the stimulation of the muscle, and restimulating the paralyzed muscle in response to said further control signal. The electrical signal is amplified, band-pass-filtered, and optionally rectified and bin-integrated when producing said further control signal. The bin-integration is performed by means of an integrator having an adjustable integration period, said integrator being synchronized with the muscle stimulator. A secure grip of an object through FES of a partially or completely paralyzed muscle which is involved in holding the object, is obtained by detecting the start of a slip of the object from the ENG signal from the nerve electrode and immediately upon detection of the start of a slip producing or modifying a control signal for activating a muscle stimulator stimulating the paralyzed muscle. The start of the slip is detected automatically as an event that exceeds a predetermined threshold value in that the ENG recorded from the sensory nerve is processed using analog or digital circuitry, and a low pass-filtered version of the ENG, delayed by a number of samples, is subtracted from the actual electrical signal sensed, thereby removing unrelated background activity from the signal.

Abstract: ABSTRACT      A device for establishing an adjustable and flexible loop to act as releasable cuffs to restrain a person or to act as a releasable tie for bundles of wire or cable.  A strap includes a free end and a lock end to receive the free end to establish a loop.  The lock has a ratchet with a set of pawls engageable with the teeth spaced along the free end of the strap.  The ratchet is hingedly mounted in the lock so that urging the strap into the lock causes the teeth to apply a rotational force to the pawls which rotates the ratchet about the hinge to disengage the pawls from the teeth to allow the strap to be inserted into the lock, while urging the strap out of the lock causes the teeth to apply an opposite rotational force to the pawls which rotates the ratchet about the hinge in the opposite direction to engage the pawls with the teeth to prevent the strap from being withdrawn.  The lock includes a keyhole to receive a key with a tab, so that the rotation of the key causes the tab to apply a force rotating the ratchet about the hinge to disengage the pawls from the teeth to allow the strap to be withdrawn.
