Patent CA-2137108-A1 (CA)
Inventor: WILSON CHRISTOPHER M
IPC: A61C13/225
Filed: 1994-12-01
Abstract: Dental appliances, including dentures, which have flange extensions attached through elastically hinged sections provide added stability and security during mastication by redistributing forces to an increased surface area and advantageously utilizing underlying intraoral bone ridges. The hinged sections allow these appliances to be installed and removed over these bone ridges. The hinged sections are biased so as to return to their original configuration once in place. Smooth conforming surfaces in contact with tissue allows these appliances to be comfortably used. Lower dentures in particular are advantageously equipped with extended flanges which are attached through hinges at the mylohyoid ridges and redistribute forces from frontal loads across the mylohyoid ridges to the submandibular fossae.

Title: Reactor for high temperature, elevated pressure, corrosive reactions
Inventor: BLANEY CAROL A
IPC: C02F11/08
Filed: 1994-12-15
Abstract: Reactor for containing high pressure, high temperature, corrosive reactions, especially supercritical water reactions. The reactor comprises an inner reactor vessel which houses the corrosive reaction, an outer containment vessel which contains a substantial level of the pressure, and insulating means to contain the high temperature of the inner reactor, which prevents the outer containment vessel from rising above a specified maximum temperature.   Using this reactor,  the lifetime and reliability of the materials of construction are increased because the outer pressure-containing vessel does not experience the high temperatures which tend to cause metals and alloys to lose ductility, and the inner reactor vessel does not experience a high pressure drop across its walls  and,  therefore,  can  be  made  of  temperature  and corrosive-resistant materials which  are not  required to sustain high stress without failure.

Title: Message device
Inventor: WILLOWS KEITH S
IPC: G11C11/34
Filed: 1995-03-16
Abstract: Microprocessor-controlled  message  devices with provision for recording, digitally storing, and playing back a voice message.  Playback of the message is initiated by a motion responsive inertial switch with  a  hairpin  actuator  or  by  a  user-accessible preview switch.  Recording is initiated by a press-to-record switch which will allow recording to proceed only for so long as the switch is maintained in a closed state by the user.  Playback is precluded while a message is being recorded.   An on-off switch is provided to disenable the inertial switch,  and an optional delay feature keeps the inertial switch from initiating message playback for a designated period after the on-off switch is closed.   Another option allows a user to adjust the sensitivity of the device to  motion.    Yet  another  control  inactivates  the recording circuitry, which keeps a stored message from being  accidentally  or  purposely  recorded over  or erased  and thereby  results  in  the  same  recorded message  being  played  back  each  time  playback  is initiated.

Patent CA-2148619-A1 (CA)
Inventor: CASTOLDI ROBERTO
IPC: B65B61/14
Filed: 1993-11-29
Abstract: The present invention provides an apparatus for applying an adhesive handle to a load, both if it is a pack of items kept together by a unitizing means such as heat-shrunk wrapping or if it is a single article such as a box. More specifically, the apparatus applies for adhesive handles to loads as they are driven along a path, the apparatus in its preferred embodiment being characterized by a rotatable lever having two opposing arms, either of the arms being in turn positioned within the path. A holding means is provided on the lever for carrying a handle to lay on a surface of the two arms of the lever with its non-adhesive side against the surface of the lever and its adhesive side exposed. Additionally a lever driving means is provided to controllably rotate the lever by about 180· after a load that is driven along the path hits an arm of the lever that is positioned within the path. With such an apparatus, the front side of each load that is driven along the path hits against a first arm of the lever, i.e., the arm positioned within the path. On that arm, one of the adhesive portions of the handle is exposed, so that such adhesive portion can be adhered to the load. Immediately thereafter, because of the impact of the load, the lever driving means is activated so as to rotate the lever by about 180· at a rotational speed so that the other arm of the lever hits the back side of the load. At that moment, the other adhesive portion of the handle, laying exposed on such other arm of the lever, is adhered to the load. Thus, the two adhesive portions of the handle are adhered to spaced portions of the load, while the non-adhesive side extends therebetween, over the load.

Patent CA-2166601-A1 (CA)
Inventor: SOLOMON DONALD D
IPC: A61J1/00
Filed: 1996-01-04
Abstract: A bottle having a sterility seal and a method for producing same are disclosed. The bottle, which can be configured to retain a medicament in powder or tablet form, features a protective cap configured to engage a transfer assembly associated with the bottle. The cap includes one or more raised ridges on an interior surface engageable with a portion of the transfer assembly. A band or layer configuration of a sealing material such as silicone is applied to the transfer assembly prior to insertion of the cap thereover. As the cap comes into surface contact with the sealing material, the ridges cause the material to "roll up" into a toroidal O-ring configuration, thereby forming a seal between the cap and the bottle adapted to the dimensional variations of those components. The seal, which is resilient, is able to withstand harsh handling treatment and pressure or temperature variations without separation from the cap or bottle, thereby providing a hermetic seal isolating the transfer assembly and, hence, the medicament from the outside environment.
