Abstract: METHOD AND APPARATUS FOR REMOVAL  OF OBJECTS FROM BODY PASSAGES                         ABSTRACT    An apparatus for insertion into the urethra for attachment to and removal of an in-dwelling urinary continence device comprises generally a tubular body having a longitudinal bore with a slidable shaft therein. Slidable jaws are connected to a first end of the shaft and are normally retained in a closed position within the bore.  The shaft may be longitudinally displaced within the bore to cause the jaws to protrude therefrom and assume an opened position.  A magnet, slidable within the jaws, protrudes from the jaws when they are in their opened position to attract a ferrous ball for retraction into the jaws.  The apparatus employs a method for removing an intraurethral device wherein anchoring members holding the device in place may be collapsed and the device removed with a single insertion of the tool.  The device may also be used for retrieving objects from body passages other than the urethra, for example, arteries.

Abstract: ABSTRACT         Chocolate is refined by so-called couching. This is carried out in a device whereby the mass is spread out in a thin film and exposed to the air. Among other things, the viscosity is reduced as a result. By subjecting the chocolate mass directly prior to the spreading in a thin film to high shear stresses, a further reduction in viscosity takes place. The invention provides a device wherein, directly preceding the spreading out in a film, the mass is subjected to high shear stresses by means of arranging radially directed pins on a drive shaft.

Abstract: PATENT ABSTRACT OF THE DISCLOSURE            A method and system are provided for mapping between an application relational database of arbitrary structure and an application knowledge base in order to permit a user to draw inferences through a knowledge base.  Also included are procedures for translating knowledge base queries into database queries, for transforming data retrieved from the database into units (structured objects) in the knowledge base and for updating a relational database based on changes made to the application knowledge base.  These procedures are supported by general purpose knowledge bases.  The method includes providing mapping knowledge bases for storing the mapping between an arbitrary relational database and the application knowledge base. The mapping between classes in the application knowledge base and the relations on a database is stored explicitly in units in a user mapping knowledge base.  These units are called class maps.  The mapping between the slots of a class in an application knowledge base and the attributes of the above relations on the database is stored explicitly in a slot of the class map corresponding to the class.

Abstract: ABSTRACT       An attachment for a flexible package is disclosed to enable the user to fasten a re-closable package.  A bifurcated adhesive member is secured to the body portion of the package at a distance from the opening thereof.  The member has a jaw-like construction with a hingeline about which one of the jaws may pivot.  When the jaws are opened by the user, the re-closed, folded end of the package may be inserted there-between, and the jaws subsequently closed to retain the package in re-closed condition.  It is particularly useful for flexible packages of corn flakes, potato chips, cheese, etc., where portions of the contents are removed over a period of time, gradually decreasing the volume of the contents and forming a sequentially smaller package which should be re-sealed to preserve the freshness of the contents.
