| 34 | Oscillatory circuit utilizing PTC resistor | US108616 | 1979-12-31 | US4320309A | 1982-03-16 | Charles R. Griffiths; William G. Ferguson |
| A control circuit for producing a repetitive closed-circuit, open-circuit condition between an electrical power source, such as a battery, and an electrical load comprises a positive temperature coefficient resistor in series with a relay coil. The PTC resistor is caused to alternate between a low resistance state and a high resistance state which permits energization and de-energization of the relay coil. | ||||||
| 35 | Combined switch and flasher | US802883 | 1977-06-02 | US4177408A | 1979-12-04 | Robert D. Mason |
| A switching apparatus to be substituted in a conventional wiring system of a building for the on-off switch of a conventional light such as a porch light for causing the light to flash on and off, the switching apparatus including a flasher wafer which is switched into and out of the circuit for the light and which flasher wafer is confined in an open and unobstructed pocket within the switch housing so as to be readily inserted and removed for replacement, the switch toggle being translucent and illuminated in synchronism with the flashing produced by the flasher wafer. | ||||||
| 36 | Flasher device | US494874 | 1974-08-05 | US3953817A | 1976-04-27 | James P. Covert |
| A flasher device includes a terminal with an inner extension carrying a stationary contact thereon, the extension supporting a conductive heat responsive means connected to another terminal of the device and having a movable contact thereon, an insulating member sandwiched between the heat responsive means and the terminal extension by a metal rivet having a head portion bearing against one of the terminal extension and heat responsive means, a shank passing through the insulating member and in spaced relationship to the defining walls of an aperture in the terminal extension through which it passes, and a staked end bearing against a washer insulating it from the other of same. The insulating member preferably has positioning projections extending into correspondingly sized apertures in the heat responsive means and the terminal extension to fix their relative position thereof. A heating coil is electrically connected across the heat responsive means and the terminal extension. | ||||||
