Abstract
1,106,350. Flashing signals. TUNG-SOL INDUSTRIES Inc. 21 July, 1966 [15 Sept., 1965], No. 32790/66. Heading G4Q. [Also in Division H1] A two terminal voltage and load compensated flasher comprises a first unit having two pairs of normally closed contacts 16, 18 and 36, 38 adapted to open upon expansion of a current responsive element 14 with passage of current therethrough, a second unit having a pair of normally open contacts 28, 30, and means operative when the contacts of the first unit are open for initiating closure of the normally open contacts. The first unit comprises a blade 12 held against its natural bias by pull ribbon 14. The second unit comprises an arm 24 welded to leaf spring 26 tending to close contacts 28, 30 but restrained by pull wire 22. When switch 42 is closed current flows from battery 45 through blade 12, ribbon 14 and contacts 16, 18 to light the lamp 40. Ribbon 14 heats up and expands allowing blade 12 to snap open contacts 16, 18 and 36, 38 when the lamp 40 goes out. The current then flows through resistor 34, wire 22 and arm 24, this is insufficient to light the lamp but sufficient to heat up wire 22 causing it to expand and allow contacts 28, 30 to close. During this time ribbon 14 has been cooling and contracting till it closes contacts 16, 18 and 36, 38. Current then flows through blade 12, contacts 36, 38, contacts 30, 28, arm 24, short circuiting wire 22 and ribbon 14, and lamp 40 is lit. Wire 22 cools down and contracts opening contacts 28, 30 thus the current flows through blade 12, ribbon 14 contacts 16, 18 and lamp 40 and ribbon 14 again heats up starting the cycle again. The time lamp 40 is off is the cooling time of ribbon 14 which is constant regardless of voltage and current and the time lamp 40 is on is the cooling time of wire 22 plus the heating time of ribbon 14 which sum is constant regardless of voltage and current. Figs. 6 and 7 (not shown) show the heating and cooling times of ribbon 14 and wire 22 and the on/off cycle of the lamp, Fig. 5 (not shown) shows an alternative unit for the second unit, this alternative unit being similar to the first unit and Figs. 1, 2, 3 (not shown) show the physical construction of an assembly of the two units, resistor 34 and terminals 4, 6. A back stop (8c) for blade 12 acts as a noise maker for an audible signal. An electromagnet may be positioned adjacent arm 24 to provide snap action for the opening and closing of contacts 28, 30.
