Abstract: A mounting for precisely positioning a sensor on an apparatus while allowing removal and replacement without disturbing the precise positioning is shown. A single combination mechanical/electrical connector is used to fix a sensor in its mounting.

Abstract: An electronic interval timer in which a cylindrical shell having five rows of LEDs mounted at spaced intervals from top to bottom, formed every 72.degree. about the circumference simulates an hourglass timer. Timer and control circuits are connected to select a desired time interval and to illuminate the LEDs and turn off successive rings in proportion to the time remaining in the selected interval at any given time after actuation. An audible buzzer is also provided as are interrupt and reset capabilities.

Abstract: A contact protected mounting for non-contact proximity sensors has a pair of sleeves and a spring mounted about the sensor. One sleeve engages the sensor, and one engages the mounting bracket. The spring is mounted between the sleeve so as to allow the sensor to recess into the mounting when contacted by a machine part so as to eliminate any damage to the sensor itself. The sleeves are configured to mount about the body of the sensor and to be readily mounted within a mounting bracket or partition to properly monitor machine motion. Both axial and perpendicular machine motion is provided for.

Abstract: A kit is provided which has a number of protective covers of a generally U-shaped cross section to be frictionally snapped about the decorative molding, trim, or other component of an automobile, to protect the textured decorative trim components from an application of wax when the car is waxed, for protection and beautification. Additional plastic protection covers are provided for door handles, antenna well, and similar components where the introduction of wax or other foreign material would adversely affect the appearance and/or performance of the component.
