Patent number: 4258942Abstract: A coupling device fitted onto an end of a hose into which a barbed nipple is inserted. The device is a rigid ferrule providing along its inner side two cylindrical portions of different diameters that are joined by a frusto-conical portion. The ferrule has a spiral thread of constant pitch formed on and along the inner side of all the portions. The thread in the larger cylindrical portion presses a shallow mating thread into the outside surface of the hose and initially advances the ferrule along the hose. The thread in the frusto-conical portion presses a progressively deepening thread into the hose and increasingly radially contracts the hose into the voids between the nipple barbs. The thread in the smaller cylindrical portion holds the hose contracted into the voids.Type: GrantFiled: May 25, 1979Date of Patent: March 31, 1981Assignee: Ideal CorporationInventor: Frank J. Viola

Patent number: 4096470Abstract: A system for alternately flashing two groups of signal lamps, as commonly employed for emergency and police vehicles, school buses, or the like, is provided with a lamp failure indicating circuit comprising two separate relay coils connected, respectively, as parts of current load lines to the lamp groups so that each coil normally will act through a contactor to energize a pilot circuit, thus causing a pilot lamp to be lighted so frequently when all the signal lamps are functional that the pilot lamp appears to be steadily illuminated; yet a relay coil will not so act, and the pilot lamp then will flash intermittantly to indicate a lamp outage, when a signal lamp on the load line of either coil does not function. In one embodiment, each relay coil has a contactor of its own in a separate branch of the pilot lamp circuit; in another, the two relay coils act alternately to displace a common contactor in the pilot lamp circuit.Type: GrantFiled: April 21, 1977Date of Patent: June 20, 1978Assignee: Ideal CorporationInventor: Samuel Kimmelman

Patent number: 4092563Abstract: Deterioration of the electrical contacts of variable load flashers provided for intermittently energizing vehicle signal lamps is inhibited by the provision of a coiled length of a current conductor having a suitable inductance value connecting the flasher contacts with at least one output terminal. In the case of a two-terminal flasher, the conductor extends to the single output terminal from a junction at the flasher contacts and in such a flasher for use in a signal lamp circuit having a relatively high current load, the coiled length is wound about a heat conductive core member connected to the single output terminal and has an inductance value of about 5.8 to 6 microhenrys. In two terminal flashers for use in signal lamp circuits having a lower current load, the coiled length may have an air core and an inductance value of about 2 to 2.2 microhenrys.Type: GrantFiled: August 30, 1976Date of Patent: May 30, 1978Assignee: Ideal CorporationInventor: Henry Parrondo

Patent number: 4001747Abstract: An improved self-biased vane structure normally buckled to an abnormal posture by a thermally expansible pull member comprises a piece of resilient sheet metal deformed downwardly relative to a horizontal reference plane between pairs of divergent creases which extend to opposite lateral edges of the piece from respective apex points spaced apart on the longitudinal center line thereof. The vane thus has a pair of triangular end panels between which there are oppositely sloped side or wing panels, and has a transversely, elastically bowed portion between the apex points. The bowed central portion may be creased longitudinally and/or formed with a central opening to give it selected buckling properties. The pull member extends centrally from end to end over the convex side of the vane; when it is heated, as by an electric current passing through it and the vane, the vane snaps toward its natural posture and brings the pull member into cooling contact with its central portion and its end panels.Type: GrantFiled: June 23, 1975Date of Patent: January 4, 1977Assignee: Ideal CorporationInventors: Ricardo Limeres, Alfred Osborn

Patent number: 3962665Abstract: An electro-thermally activated liquid level sensor that functions reliably under widely varying conditions of ambient temperature and supply voltage makes use of an elongate bimetal element cantilevered at one end thereof in a heat conductive wall adapted to be contacted by the liquid and heated by an electrical resistance element, e.g. by a resistance wire wound about the bimetal element and grounded through it, so that the free end of the bimetal element will close cntacts for a signalling circuit when liquid is not contacting said wall and will open the contracts in response to the loss of heat through the fixed end when liquid is contacting said wall. The bimetal element is composed of oppositely oriented bimetal strip segments fixed one to an end of the other and proportioned with the windings of the resistance wire, so that the switching action of the free end is not voltage-dependent; i.e.Type: GrantFiled: February 13, 1975Date of Patent: June 8, 1976Assignee: Ideal CorporationInventors: Edward Wojcik, Ricardo Limeres
