Abstract: An inductive liquid-level sensor employs a central shaft supporting multiple independent electrical loops that may be interrogated to detect the proximity of the conductive element in the float rising and falling with changes in liquid height outside of the shaft.

Abstract: A self-diagnostic acoustic wave touch actuated switch assembly includes a substrate having an acoustic wave cavity, a transducer operatively connected to the acoustic wave cavity, a processing unit, and at least one light emitting member operatively connected to the processing unit. The transducer is configured to generate a trapped acoustic wave within the acoustic wave cavity. The processing unit is operatively connected to one or both of the acoustic wave cavity and/or the transducer. The processing unit may be configured to activate the at least one light emitting member when the processing unit detects one or both of a switch malfunction and/or a potential switch malfunction.

Abstract: A buckle assembly including a first buckle portion having an outwardly projecting engagement member. The assembly further includes a second buckle portion including an extended socket structure with one or more resilient biasing arms disposed radially outboard of the extended socket structure. A sleeve member is disposed in reciprocating relation to the second buckle portion at least partially about the extended socket structure. A camming surface is disposed in substantially fixed relation to the sleeve member radially outboard from the resilient biasing arms. The camming surface includes at least one concavity engaging one or more of the resilient biasing arms.

Abstract: A damper assembly includes a fixed rack gear, a rotary gear damper having a gear engaged with the rack gear, and a tether movable with the damper along the rack gear and connected to the movable object to be controlled by the damper. A biasing element normally urges the damper away from anti-rotation locking members.

Abstract: An apparatus and method for molding a component onto a stretched blank. The apparatus includes a stretching assembly mounted adjacent to a first mold part. The stretching assembly includes a plurality of clamp assemblies that grasp the peripheral edge of the blank and a plurality of slide assemblies that move the clamp assemblies away from one another to apply a stretch to the fabric. The apparatus further includes a press for closing a second mold part onto the first mold part while the fabric is held in a stretched condition by the stretching assembly. In one embodiment, the stretching assembly may include a float plate that is movable with respect to the first mold part between a stretch position and a mold position. The apparatus may include a robot with tooling for moving the fabric onto the stretching assembly. The tooling may include a plurality of shot pins that push the fabric off of the tooling onto corresponding fabric pins in the stretching machine.

Abstract: A self-calibrating sensor includes a housing, an input lever coupled to the housing and configured to contact a device to be sensed, and an actuating element configured to automatically reposition an output device to a calibrated position. The sensor also includes a cam ring that is configured to move the output device to the calibrated position based on an input received from the actuating element and a lock ring coupled to the input lever. In one exemplary embodiment, the output device is an electrical contact assembly that is slidably engaged with the cam ring. During operation, the cam ring is configured to reposition the electrical contact assembly based on the input received from actuating element.

Abstract: A method of reducing if not eliminating the possibility of tearing or ripping of a mesh screen of a filter during the manufacturing process includes the step of intentionally deforming the mesh screen. With this technique, as the plastic material that forms the frame of the filter begins to expand or change shape, as a result of the heating and squeezing steps involved with the molding process, the deformed mesh screen will be able to accommodate the relative changes in shape without tearing or ripping of the mesh screen. With the invention, numerous shapes and configurations of tools may be used to provide the intentional deformation of the mesh screen during the manufacturing process as well as to provide for control over the amount and degree of mesh screen deformation. Also, the resulting filter will have a mesh screen that has improved retention capabilities which will enhance the performance of the filter.

Abstract: A cage nut assembly includes a cage, a nut and a heat sensitive adhesive. The cage includes a plurality of walls defining an internal chamber and an open end. An opening is formed through one of the walls. The nut is secured to the cage within the internal chamber. The nut includes a threaded channel exposed through the opening. The heat sensitive adhesive adhesively secures the nut to the cage within the internal chamber. The nut breaks away from the cage within the internal chamber when heat is applied to the heat sensitive adhesive.

Abstract: A molding retainer is provided for securing a molding to a return flange in a roof ditch. The retainer generally includes a throat, a stop, a molding seat and a molding clip. In the case of a discontinuous flange having individual flange coupons, the throat may define a through-hole that fits over each flange coupon. The throat may include a plurality of fingers adapted to snap fit into windows in the flange coupons, with the fingers being mounted at different heights to accommodate variations in the placement of the windows. In the case of a continuous flange, the throat may define a channel that fits over the flange. The stop engages the floor of the roof ditch to provide a reference point for the height of the molding, and the molding clip engages and holds the molding.

Abstract: A connector includes an elongated hollow body and a nut threaded onto the body. The nut is secured in place by outward expansion of material from the threaded body into a chamfer of the nut.
