Patent CA-2269691-A1 (CA)
Title: Acoustic communicator for central vacuum cleaners
Inventor: LINDSAY EDWARD W JR
IPC: A47L5/38
Filed: 1999-04-22
Abstract: A wireless acoustic communicator is disclosed which permits a remotely-located operator to monitor and control a central vacuum cleaner. The acoustic communicator does not need problematic batteries, airflow blockers, or special wiring networks but uses only low-frequency acoustic signals that are transmitted through the pipe system of the vacuum cleaner. Command signals are effectively transmitted, even while air is flowing through the pipe system, by using a continuous multi-frequency signal, a resonant physical structure, and an adaptive signal detector. A preferred embodiment uses a powerful reed to generate a continuous acoustic signal. The reed is manually plucked by a slide switch to start vibration, which is then continued by the airflow through the pipe system caused by the running vacuum motor. The vacuum motor runs only if the signal is present. The acoustic communicator includes a resonant detection tube that filters the signal before it reaches a microphone. The adaptive signal detector reacts to noise and airflow sensed with a microphone by tracking signal phase, altering detection criteria, and sampling independently in time, frequency, and space. In addition, the wave form of the acoustic signal can be changed to create a control signal for other central vacuum cleaner functions, such as motor speed control. The acoustic communicator can also be used to monitor the central vacuum cleaner; for example, it can report a full condition of the dust filter.

IPC: B29C65/00
Filed: 1997-11-20
Abstract: Apparatus for heat-sealing polymer films which shrink when heated include provision for moving the zone of application of heat and pressure during the heat sealing process. This allows for shrinking of the polymer film in a region adjacent to the heat seal so that the film thickens and is more resistant to failure in use through peeling. The apparatus includes a pair of sealing bars (4, 5) one of which (4) is wedge-shaped and the other of which (5) is flat. Both bars are heated and one of them can be moved in direction 12 to apply pressure to film located between the bars. At the beginning of the heat sealing step pressure is applied over an initial zone along the apex of the wedge. Subsequently the bar 4 is rolled around an axis located near to the apex of the wedge, in the direction shown by the right hand end of arrow 13, to apply heat and pressure over a wider zone located adjacent to the initial zone.
