Abstract: A latch assembly for a movable closure element. The latch assembly has a housing with first and second rotors each movable relative thereto between a first latched position, a release position, and a second latched position. The first and second rotors in their first and second latched positions define a receptacle with an effective diameter and a center line that is angularly disposed to the line of a straight edge on the housing. With the rotors in their first latched positions, the center line of the receptacle is spaced from the first line a first distance. The center line of the receptacle is at a first location with the rotors in their first latched position and a second location with the rotors in their second latched positions. The first and second locations are spaced a second distance. The effective diameter of the receptacle, with the first and second rotors in their first latched positions, varies from each of the first and second distances by no more than ±40%.

Abstract: A latch assembly kit including a latching subassembly, a first actuating assembly having a first configuration and normal and release states, and a second actuating assembly having a second configuration and normal and release states. The latching subassembly has a latched state, and a release state. The first actuating assembly is mountable on the first side of a movable closure element and causes the latching subassembly to change from its latched state into its release state as an incident of the first actuating assembly changing from its normal state into its release state. The second actuating assembly is mountable in place of the first actuating assembly and causes the latching subassembly to change from its latched state into its release state as an incident of the second actuating assembly changing from its normal state into its release state.

Abstract: Methods and apparatus to characterize a welding output circuit path. A welding output circuit path is characterized in real time with respect to a true energy and/or true power input to the welding output circuit path. A welding output circuit path is also characterized with respect to an inductance of the welding output circuit path. A welding output circuit path is further characterized with respect to a welding output waveform.

Abstract: A latch assembly for a movable closure element. The latch assembly has a housing, a first rotor movable relative to the housing selectively between a) a first latched position and b) a release position, and a second rotor movable relative to the housing selectively between a) a first latched position and b) a release position. The first rotor has a first throat to receive a strike element. The latch assembly further has an operating assembly with a latched state and an unlatched state. The operating assembly in the latched state releasably maintains the first rotor in its first latched position and the second rotor in its first latched position. The first rotor is movable substantially parallel to a reference plane as the first rotor moves between its first latched and release positions. The first rotor has a non-uniform thickness taken orthogonally to the reference plane.

Abstract: A latch assembly for a movable closure element of the type having first and second sides. The latch assembly has a housing, a first rotor movable relative to the housing selectively between a) a latched position and b) a release position, and an operating assembly which is operable to change the first rotor from the latched position into the release position. A first rotor is engageable with a strike element relative to which the movable closure element can be moved to thereby releasably maintain the movable closure element in a desired position. The first rotor is biased towards the release position. The operating assembly includes a catch block assembly that is movable selectively between a) an engaged position wherein the first rotor is maintained in the latched position and b) a disengaged position wherein the first rotor is permitted to move from the latched position into the release position.

The operating assembly has a catch arm that is movable relative to the housing from a first position into a second position to thereby change the operating assembly from the latched state into the unlatched state.

Abstract: A latch assembly for a movable closure element. The latch assembly has a housing with a peripheral edge defined in part by a substantially straight edge portion extending along a first line. A first rotor is movable relative to the housing selectively between a) a first latched position, b) a release position, and c) a second latched position between the first latched position and the release position. A second rotor is movable relative to the housing selectively between a) a first latched position, b) a release position, and c) a second latched position between the first latched and release positions for the second rotor. An operating assembly has a latched state and an unlatched state. The operating assembly in the latched state releasably maintains the first rotor in its first and second latched positions and the second rotor in its first and second latched positions.

Abstract: A latch assembly kit including a latching subassembly for mounting upon a movable closure element, a first actuating assembly having a first configuration and normal and release states, and a second actuating assembly having a second configuration that is different than the first configuration and normal and release states. The latching subassembly has a latched state, wherein the latching subassembly releasably engages a strike element to maintain the movable closure element in a desired position relative to a support to which the movable closure element is attached, and a release state. The first actuating assembly is mountable on the first side of the movable closure element and causes the latching subassembly to change from its latched state into its release state as an incident of the first actuating assembly changing from its normal state into its release state. The second actuating assembly is mountable to the first side of the movable closure element in place of the first actuating assembly.
