  • Patent number: 4942386
    Abstract: An impact sensing and alarm system having a dual adjustment impact system and alarm circuit for activating selected alarm devices in conjunction with tamper switches connected to provide additional protection to critical areas of a machine. The impact sensor provides dual sensitivity with an adjustable conically tapered spring circumjacent an adjustable threaded contact. The spring is adjustable for coarse setting of the impact loading range and is then fixed. The threaded contact is adjustable to fine tune the threshold sensitivity. An alarm circuit is provided which is constructed to activate visible, audible or silent remote alarms. The impact alarm system is encapsulated to prevent access except to the adjustable threaded contact, and is simple and compact enough to be adaptable to protect any coin-operated or other electronic device.

  • Patent number: 4167166
    Abstract: An arrangement for inducting auxiliary heated air into the intake manifold of a carbureted internal combustion engine in an efficient, optimal manner, which achieves substantially complete vaporization of the fuel with a relatively low volume of auxiliary air. The arrangement includes an air induction tube receiving filtered air, which tube is connected to a heater tube disposed within the interior of the exhaust system or to a hot water heat exchanger to heat the auxiliary air, which is then inducted into the engine intake manifold via an insulated double wall tube and a metering block which produces a controlled flow of the heated air into a pair of distributor tubes extending from the metering block into branch cavities of the engine intake manifold.

  • Patent number: 4151507
    Abstract: An alarm system for vehicles or the like responsive to unauthorized tampering. The circuitry includes at least two sensor arrays, each adapted to produce a signal responsive to tampering of a particular kind. In the case of an automobile, one sensor array is responsive to the opening of the trunk or hood, and its signal immediately actuates an alarm, such as sounding the horn; another sensor array, responsive to movement of the vehicle or opening of a door, produces a signal which, after a time delay of, say, 15 seconds, actuates the alarm. Another time delay circuit turns off the alarm after, say, 25 seconds. The circuitry includes arming means incorporating a third time delay, by which to arm the system after a delay of, say, one minute following the turning off of the ignition switch.
