  • Manual release and test apparatus for alarm system
    Patent number: 4154189
    Abstract: A manually operated release and test apparatus is disclosed for use with mechanically powered protection devices. A spring powered fire alarm, for example, is triggered either by exposure of its sensitive fusing element to a predetermined temperature, or by complete physical removal of the sensitive fusing element from the device. The release and test apparatus of this invention is a lever mounted on the alarm device for the consistent removal of the fuse assembly for testing the alarm while avoiding inflicting any damage thereto. This apparatus facilitates the testing and demonstration of the alarm device, without modifying the aesthetic appearance of the alarm. Also disclosed is a chain attachment which permits a remote force to be directly applied to the release lever so as to provide a release and test means for manual activation of the alarm in emergency situations.

  • System for monitoring integrity of communication lines in security systems having remote terminals
    Patent number: 4155073
    Abstract: A line monitoring system is disclosed which provides particular advantages to security systems having remote terminals. This system provides both a reduction in the required power for the line monitoring task and also increases the level of line security by generating a calculated response at the remote terminal, which calculated response could not be accidentally produced by a faulty remote unit. Futhermore, the calculated response at the remote unit greatly reduces the likelihood of clandestine entry at the remote site.

  • Nylon hose treated with microencapsulated hair dissolving solution
    Patent number: 4152784
    Abstract: A fabric garment which automatically removes unwanted hair while being worn against the skin of the user. The garment is coated with a pressure sensitive microencapsulated depilatory agent. Pressure exerted by a hair stubble against the fabric causes the microencapsulation to rupture and dispense the depilatory agent in a small localized area around the hair follicle. The depilatory agent dissolves the hair stubble without irritating the user's skin.

  • Fuel injection split engine
    Patent number: 4146006
    Abstract: A circuit is described for a multiple cylinder engine which permits operation of all of the engine cylinders or a part thereof in response to engine loads. Different operating modes, incorporating different numbers of cylinders, are activated in a fuel injection engine in response to varying power demands. Manual switching circuits on the dashboard of the automobile permit the driver to override the automatic system and require that the engine operate in any of its operating modes. When operating in partial modes, a circuit automatically rotates the cylinder banks which are operated to assure uniform engine wear and cooling. Switches are provided on the dashboard to permit the operator to selectively skip certain engine modes in the automatic, load-responsive sequencing of engine operation.

  • Single mount electrical control device assembly
    Patent number: 4144555
    Abstract: A combination of a potentiometer and an integrated circuit module are mounted on a printed circuit board which interconnects these members and provides for external connections. Mechanical mounting of the printed circuit board, the potentiometer, and the integrated circuit module is provided by a single mounting bushing of the potentiometer. The mounting arrangement also permits a heat sink tab on the integrated circuit to be clamped by this mounting bushing directly against the front panel of a user's equipment. Thus, the single mechanical mounting connection for the combination at the potentiometer bushing not only mechanically mounts all of the elements but additionally provides a heat sink connection for the circuit. At the same time, the use of the printed circuit board in this combination permits automated assembly and soldering which substantially reduces the cost of the circuit.
