Patent number: 4616928Abstract: A photoelectric smoke detector including a housing defining a test zone and an opening for admitting smoke thereinto, a light source arranged to direct light to the zone and a light responsive element arranged to receive light scattered by smoke particles in the zone. An optical barrier prevents the direct transmission of light through the zone and between the light source and light responsive element, the barrier defining a light passage for transmitting light directly therebetween. Projecting into the light passage is a mechanical gate that can be adjusted to alter the size of the light passage and thereby vary the level of light transmitted directly therethrough between the light source and the light responsive element. In response to selective adjustment of the mechanical gate, the light responsive element can provide a background signal that obviates normal electronic noise.Type: GrantFiled: June 20, 1984Date of Patent: October 14, 1986Assignee: Kidde, Inc.Inventors: George E.

Patent number: 4521180Abstract: A laboratory gas burner and control apparatus including a burner assembly made from electrically conductive material and adapted for positioning on a counter. Defined by the burner is an inlet for connection to a gas source and an outlet for feeding gas to a flame. An electrically operated valve controls the flow of gas to the burner outlet and an igniter is energizable by a power supply to ignite gas emanating from the burner outlet. Associated with the igniter is an activation circuit that produces either ignition periods during which the igniter is energized by the supply or non-ignition periods during which the igniter is deenergized. Initiation of each ignition period requires manipulation of a manual activation mechanism. Once ignited, the presence of flame at the burner outlet is detected by a flame sensing mechanism. A valve control circuit maintains the supply valve open only during either ignition periods or periods during which flame is detected by the sensing mechanism.Type: GrantFiled: June 11, 1984Date of Patent: June 4, 1985Assignee: Kidde, Inc.Inventors: Carl W.

Patent number: 4512482Abstract: A crane boom extension or jib is held on the nose of the boom by a single fixed length self-adjusting cable loop which extends around an arcuate guide attachable at several different locations to an inclined plane mounting bracket on the jib near its outer end. The mere repositioning of the guide on the inclined plane mounting bracket allows the jib to assume several different angularly offset positions relative to the axis of the boom without other adjustments. The inclined plane mounting bracket establishes the plane in which the cable loop lies in all adjusted positions of the jib. The arrangement is convenient, safe and simplified.Type: GrantFiled: February 15, 1983Date of Patent: April 23, 1985Assignee: Kidde, Inc.Inventor: William R. Mentzer

Patent number: 4502584Abstract: This disclosure is directed to a coin slide assembly having a coin slide disposed for accommodating up to eight coins in a vertical position. The assembly further includes sets of inter-engaging channels and post on the assembly housing and on the coin slide, respectively, to restrict access to the internal blocking dog components of the assembly by persons intent on damaging or interferring with the normal operation of the dogs. A gate is provided through which the coins pass upon inserted movement of the coin slide. The assembly further includes a coin sizing block having inverted V-shaped notches which cooperate with the blocking dogs to render the coin slide operative only when properly sized coins are carried by the slide. A protective bar restricts the movement of the blocking dogs beyond their non-blocking position to prevent distortion of the spring which biases the dogs to their normal blocking position.Type: GrantFiled: September 30, 1982Date of Patent: March 5, 1985Assignee: Kidde, Inc.Inventor: Christos Lambiris

Patent number: 4484686Abstract: A side stowable swing-around boom extension is pinned on the nose of a telescoping crane boom in a first use position nearly coaxial with the center line of the boom but tilted or offset therefrom at a small angle. Two larger angularly offset use positions of the boom extension are obtained with convenience and with complete safety while the crane boom and boom extension are at a near ground level position. Two slotted tension links are connected between the upper side of the boom extension and the boom nose and are allowed to support the boom extension in either of two major offset use positions automatically as the crane boom is elevated from the near ground level position. In such operation, the boom extension is allowed to rotate around the axis of its lower side pivotal connection with the boom nose while its upper side connection with the nose is released. The lower side connection is biased toward a position corresponding to the nearly coaxial use position of the boom extension.Type: GrantFiled: April 23, 1982Date of Patent: November 27, 1984Assignee: Kidde, Inc.Inventor: William R.
