Title: Dental floss provided with chemotherapy agents
Inventor: SIMIONATO LUIZ BELLINO
IPC: A61K8/02
Filed: 1994-06-07
Granted: 2008-07-29
Abstract: Dental floss provided with chemotherapy agents, including wax that is emulsible upon contact with saliva. State of the art dental flosses achieve an efficient release of active agents within the oral environment, by using soluble waxes, but said solution decreases comfort of application since there is a de-crease in the levels of sliding and penetration between the teeth, in comparison to the use of insoluble waxes. The use of said emulsible wax allows for an efficient release of the chemotherapy agent through the oral environment - preferably fluoride ions - while maintaining the same levels of sliding and penetration between teeth as are obtained with insoluble wax.

Abstract: The refilling container of the present invention is a simplified container for use in containing a refilling detergent and the like. A number of the refilling containers can be laied at a limited space. The refilling container can be refilled with a content easily and surely, and can be disposed easily. The refilling container is comprised of a thermoformed container body and a seal film for sealing an opening positioned at the lower end of the container body. A tapered cylindrical shoulder portion is continuously connected to the upper end of the barrel portion of the container body, and from the center portion of the shoulder portion, a nozzle cylinder 4 closed by a platen 21 at the extreme end thereof extends upwardly, In case of such as refilling a content in the container body or displaying the refilling container after filled with a content, the refilling container is converted to the state of the shoulder portion being subsided in the barrel portion, while in case of reffilling a content in another container, it is converted to the state of the shoulder portion being projected from the barrel portion and then the extreme end of the nozzle cylinder is cut to form an injection port.

Abstract: A mechanism for adjusting the height of a frame of an agricultural implement relative to a groundsurface is described. A parallelogram frame is provided which includes a frame mounted member and a wheel mounting member parallel to the frame mounted member. The frame mounted member is secured in substantially vertical orientation to an end of a transverse support member of the frame of the agricultural implement. A stub axle is secured substantially perpendicularly to a face of the wheel mounting member remote from the transverse support member with a ground engaging wheel rotatably mounted on the stub axle. An expandable jack is mounted to the top of the transverse support member. Upon expansion of the jack a force is exerted upon an upper connecting member causing the parallelogram frame to pivot until a first end of the upper connecting member to which the end of the transverse support member is attached is raised relative to a second end of upper connecting member. Upon contraction of the jack a force is exerted upon the upper connecting member causing the parallelogram frame to pivot until the first end of upper connecting member to which the end of the transverse support member is attached is lowered relative to the second end of upper connecting member.

Abstract: In a method of manufacturing a semiconductor device comprising a semiconductor chip and a carrier film which includes an insulating film and wiring patterns formed on one of main surfaces of the insulating film, an adhesive layer is formed on a surface of a semiconductor wafer having a number of integrated circuits. Each of the integrated circuits has electrode pads for external connection on the foregoing surface of the semiconductor wafer. Subsequently, openings are formed at regions of the adhesive layer corresponding to the electrode pads, and then, the integrated circuit is cut from the semiconductor wafer so as to obtain the semiconductor chips.      Thereafter, the electrode pads of the semiconductor chip and the wiring patterns of the carrier film are connected to each other through the corresponding openings of the adhesive layer, respectively. Then, the semiconductor chip and the carrier film are bonded together via the adhesive layer interposed therebetween. It may be arranged that the adhesive layer is formed on the carrier film rather than on the semiconductor chip.

Title: Communication system including method and apparatus for maintaining communications with a mobile terminal
Inventor: NAGHSHINEH MAHMOUD
IPC: H04L12/56
Filed: 1996-03-01
Granted: 2001-07-03
Abstract: A communications network having a number of routers, a number of base stations and a number of mobile units maintains communications with the mobile units by assigning a unique address known to the routing entities of the network to each mobile unit. By including the mobile units unique address in topology updates of the network, the location of the mobile unit at any time is made known to all routers of the network. That is, once a mobile unit moves into a domain of a new access point and establishes a new link with the new access point, it uses the topology update mechanism of the network to make its new location known to all routers. Once a router of the network receives topology update information specific to the mobile unit's new location, it updates its routing table such that packets destined to the mobile unit are routed in a path which terminates at the mobile unit and contains its new access point.

Title: Hardfacing for progressing cavity pump rotors
Inventor: MILLS ROBERT A R
IPC: F04C2/107
Filed: 1996-03-04
Granted: 1999-02-02
Abstract: A hardfacing for downhole progressing cavity pumps is disclosed as well as a method for producing same. The hardfacing consists of a metal carbide layer applied to the ferrous pump rotor body by way of plasma spraying and a top layerof metallic material having a lower hardness than the metal carbide. The metal carbide layer has a grainy surface with a plurality of peaks and intermediate depressions, the peaks being formed by metal carbide grains at the surface of the metal carbide layer. The thickness of the top layer is adjusted such that the depressions between the peaks of the metal carbide layer are completely filled thereby providing the rotor with a metal carbide hardfacing of significantly reduced surface roughness. In the process of the invention, the pump rotor, which may beprovided with a molybdenum bonding layer, is plasma coated with the metal carbide and the resulting carbide layer is covered with the metallic material top layer. The top layer is polished either until the dimensions thereof are within the tolerances acceptable for the finished rotor or until a majority of the peaks of the carbide layer are exposed. The hardfacing significantly increases the service life of the rotor and stator of downhole progressing cavity pumps.

Abstract: A new method for defrosting a dehumidifier. The new method minimizes the formation of liquid "slugs" which can occur during normal defrosting and which can damage the compressor, and also makes the operation of the dehumidifier more efficient. In the new method, defrosting take place with the fan running to draw warm, room air over the condenser to warm the refrigerant passing through it in reverse, to thus minimize the formation of liquid "slugs". The warm air however is prevented by baffles from passing over the evaporator where it would undesirearably pick up moisture from the melting ice on the evaporator. An apparatus for carrying out the above method is also provided.

Abstract: A pair of cross brace members are diagonally positioned within an internal cavity of a refrigerator door shell that is defined by an outer front panel, side walls and in-turned, return flanges. The cross brace members are generally L-shaped in cross-section and are inter engaged at central portions thereof which are specifically configured with respective cut-out connection portions to aid in assembly and positioning of the cross brace members. The cross brace members have tabs at terminal ends thereof which extend above planes defined by generally horizontally extending upper sections of the cross brace members. These tabs are adapted to rest upon respective ones of the return flanges to initially mount the cross brace members within the door shell. Once the cross brace members are appropriately positioned with the door shell, insulation foam is supplied into the internal cavity. The foam flows through longitudinally spaced holes provided in generally upright sections of the cross brace members and around the cross brace members. Once the insulation foam hardens, the cross brace members become fixed to the door shell such that a reinforced refrigerator door assembly is defined. An inner door liner can then be attached to the return flanges.
