Title: Fire extinguishing systems and methods
Inventor: STEHLING HENRY J
IPC: A62C35/13
Filed: 1996-05-31
Abstract: In a preferred embodiment, a fire extinguishing system for suppressing fires on cook stoves, fryers or other heating or heated devices with fire suppressant dispensed through nozzles is powered by batteries which pro-vide current for both a detection circuit including a pair of heat sensors and control circuitry and current for a gas or electric house current shut-off. Preferably, the shut-off is operated acoustically upon sounding of an audible alarm which emits a signal to which the shut off is acoustically tuned. Pre-ferably, the heat sensors are diodes but, in alterative embodiments may be thermistors or active temperature sensors. While a wireless link, such as an acoustical link, is preferred between the control circuitry and shut-off, a wired link may also be used. In order to facilitate mounting of both the heat sensors and nozzles, magnetic housings are utilized which retain studs extending from tees, 90 degree elbows or both. A heat sensor housing is secured to the magnetic mount by magnetic force, which heat sensor hous-ing is in turn held securely proximate the heat source at appropriate locations.

Patent CA-2193276-A1 (CA)
Title: Method and apparatus for telephone call sub-billing
Inventor: PENZIAS ARNO ALLAN
IPC: H04M15/00
Filed: 1996-12-18
Abstract: A "breakout" of telecommunications toll calls on a per-station basis is providedto households or other telecommunications endpoints which have subscribed to only a us single analog telephone line. Subscribers wishing to avail themselves of such "station set billing" will have purchased and installed telephone stations sets which are adapted to transmit to the telecommunications service provider, during a call, e.g., at the start thereof, a signal carrying a code which identifies that station set. The subscriber, additionally, will have registered the station set's code, which may be marked on the bottom of the instrument, with the telecommunications service provider. Thus the service provider is able to identify which station set within the household a call is being made from or to which a collect call is being made. The telecommunications service provider can thus readily "tag" the toll charge for that call in the subscriber's monthly bill as having been made from, or billed to, a particular station set, hereby effectuating the inventive "station set billing" service. The station set may transmit the code at its own initiative. Alternatively, it may transmit the code in response to a query signal issued by the telecommunications service provider's equipment during call set-up. Preferably, the station set's code signal, as well as the query signal are of a type that cannot be heard by the human auditory system, such as a spread spectrum signal, thereby making the interchange of query and identifying signal imperceptible to the callers.
