Title: Facility for the making of composite multilayer structures by drape moulding
Inventor: MORIZOT RICHARD A P
IPC: B29K105/08
Filed: 1993-06-29
Abstract: In order to produce multilayer structures made of composite materials, by draping pre-cut elementary layers over a forming die (12), an installation is proposed comprising, in addition to the forming die (12), a gripping tool (16) capable of being mounted, for example, on the articulated arm of a robot. The forming die (12) comprises a flexible membrane (28), equipped with suction suckers (58) which grip the pre-cut elementary layers. A vacuum circuit (48) enables the membrane (28) to be pressed up against a counter-shape (26) placed behind the latter, in order to shape the elementary layer picked up. When the tool (16) is brought onto the die (12), a pressure source (52) acts on the membrane (28) in order to compact the elementary layer on the die. A suction system (76, 82) keeps this layer on the die, after releasing the suction via the suckers (58). <IMAGE>

Title: Protection process of magnetic powders and fe nd b permanent magnets against oxidation and atmospheric corrosion
Inventor: SAGAWA MASATO
IPC: C04B35/00
Filed: 1994-01-05
Abstract: This invention relates to a method of protecting magnetic powders and permanent magnets containing at least one rare earth, at least one transition metal and boron, against oxidation and atmospheric corrosion by introducing gaseous fluorine during the grinding of the powders. It is characterised in that the fluorine is introduced using a F2 + N2 mixture during the fine grinding of the powders, this mixture containing between 1 and 100 ppm (by volume) of fluorine, and preferably between 1 and 10 ppm. The powders thus obtained are markedly less reactive and the densified magnets are markedly more resistant to atmospheric corrosion than non-fluorinated powders and magnets obtained from the latter.

Title: Method and Apparatus for Heating of Bulk Materials
Inventor: KORTSCHOT CORNELIS
IPC: A23G1/18
Filed: 1994-07-27
Abstract: Heat is applied to a solid or semi-solid material in a cylindrical container in such a way that a precise, predetermined amount of heat is transferred to a horizontal layer of the material until it softens sufficiently to allow the heating element to sink into the material where it will heat the next layer.  The container is rotated about a vertical axis, and a horizontally-oriented heating element is lowered into contact with the material to apply heat to a horizontal layer.  The heating element is lowered through the material in a controlled manner to heat progressively lower layers within the container, until the whole container has been heated.  The heating element may be heated by pumping hot water therethrough, or by other means.  A container of hot liquid may be cooled in a similar fashion, by gradually raising a cooling element from the bottom of the container.

Title: Portable oral tooth brush
Inventor: CHENG DANNIE
IPC: A46B11/00
Filed: 1994-09-26
Abstract: ABSTRACT OF THE DISCLOSURE   A Portable pen size brush for tooth comprises a brush head section with an elongated longitudinal axis having a hollow canal from the base (Distal end) to the bristle area (Proximal end) of the brush head which allows tooth cleaning or bacterial preventing or protecting or whitening (agents or gel and or paste form) and or any of the above combinations to travel from the distal end to the proximal end when pressure is apply by the mechanical actions in the handle section. The handle section consist of a longitudinal hollow tube (capable of storing the above mentioned agents,paste,  or gel) with both proximal and distal end threaded internally for attachment to the brush head section and the rotary end unit. When handle section is not connected, common tooth paste tube can be thread into either  end to provide refill tooth paste into the hollow of the handle section. The rotary end unit consist of an elevating system which raises or lowers a platform within the handle when turned. The portable tooth brush is a seal system. Where when the rotary end unit is turned, the platform will push tooth paste inside the handle towards the distal end of the brush head section, where the tooth paste will travel to the proximal end of the brush head, exiting to the bristle of the brush head section. The brush head section will be covered (caped) when not in use. This system provides more brushing opportunities for everyone, since tooth paste and tooth brush are build into a single pen size portable system.

Title: Ablation catheter positioning system
Inventor: NARDELLA PAUL C
IPC: A61B5/296
Filed: 1993-06-16
Abstract: A multi-electrode cardiac catheter (10) has pairs of electrodes (13) connected to sensing circuitry (31, 32, 40) to produce a differential signal. The sensing output is sharply defined and self normalizing.  Preferably, a catheter ablation tip electrode (12) is an electrode of one pair, and the differential signal becomes non-zero when the tip contacts surrounding tissue. The shape of the differential signal provides information on the degree of electrode contact, as well as on the amount of locally-sensed tissue im-pedance change. The signal may be used as a trigger enable signal for a cardiac ablation catheter (10), and the applied level of RF power may be controlled based on the indicated degree of electrode contact and value of tissue impedance.
