| 137 | Interfacing attachment for remote mechanical fire alarms | US211382 | 1980-11-28 | US4389635A | 1983-06-21 | Edward L. Gallagher |
| An attachment which converts a single station, spring powered, temperature sensitive, fire alarm protection device into a remote signalling heat detector for a central fire alarm system, without affecting the internal apparatus of the alarm device or the environmental protection of such internal apparatus. The attachment includes a pivotally mounted member having a shield arm interposed between a magnet and a reed switch, and a lever arm which interacts with a winding key on the alarm device to move the shield arm from between the magnet and reed switch when the alarm is actuated. This movement of the shield arm permits the magnetic force of the magnet to activate the reed switch. The reed switch is connected by wire or radio link to a central monitor. Actuation of the reed switch, in response to actuation of the alarm device, produces an alarm signal at the central monitor. | ||||||
| 138 | Proximity sensing transducer with simulation means | US968847 | 1978-12-12 | US4365196A | 1982-12-21 | Colin M. Finch |
| A transducer having a field creating coil arrangement which produces a field having a field strength minimum, having a sensing coil positioned at that field strength minimum and responsive to changes in position of that minimum resulting from the proximity of an article to the field creating coil arrangement. By observing changes in the signal output of the sensing coil, information concerning the proximity of an article to the transducer is ascertained. Preferably the transducer includes a field disturbing means associated therewith for inducing a disturbance to the field created by the field creating coil so as to cause the sensing coil to operate by either simulating the disturbance of the field that would be caused by the proximity of an article or by changing the field while the article is present. Thus the transducer may be remotely checked as to its operation. | ||||||

| A system controlling apparatus wherein an array of sensors are used for detecting information and for providing signals indicative of information concerning passing articles such as presence of an article at a sensor, number of articles passing, the direction of passing and the velocity of passing. Signal processing apparatus is comparing the signals with pre-determined parameter information as to the system and for providing control to the system in response to detecting equality and for providing overriding control to the system in response to detecting inequality. Each of the sensors is self-checking during the period an article is not present. The information detected by the sensors is converted to a simple binary high or low signal and such binary signals from all sensors are compared in a "look-up" table comparator arranged to recognize a particular pattern of highs and lows at its input and to provide an output to the system if it is in accordance with a pre-determined pattern corresponding to the pre-determined parameter information of the system. | ||||||
| 140 | Liquid level sensor | US660170 | 1976-02-23 | US4082930A | 1978-04-04 | Denny L. Peeples |
| A liquid reservoir such as that for a brake master cylinder has a float in the liquid, a magnet and a reed switch secured to the float at a fixed spacing so that normally at high liquid level the reed switch is in a given state. When the liquid level falls, the float approaches a body of magnetic material suspended at a desired level in the reservoir or the bottom of the reservoir which comprises magnetic material. When low liquid level is reached, the body of magnetic material alters the flux field from the magnet to either increase or decrease the influence the magnet on the reed switch to cause a change of state of the reed switch thereby indicating low liquid level. | ||||||
