A low voltage light novelty decoration that includes a substantially hollow and decorative main portion, a generally circular-shaped base portion, and adjusting apparatus. The substantially hollow and decorative main portion has a shape that identifies a specific event and provides an optical recognition that associates the specific event in a mind of a viewer. The generally circular-shaped base portion is integrally formed and has an exposed outer surface, a substantially concealed inner surface, a center, and a centrally-disposed, inwardly-tapering, longitudinally-oriented, and generally circular-shaped throughbore. And, the adjusting apparatus is associated with the generally circular-shaped base portion for adjusting the diameter of the centrally-disposed, inwardly-tapering, longitudinally-oriented, and generally circular-shaped throughbore to substantially equal the diameter of the light portion if the diameter of the centrally-disposed, inwardly-tapering, longitudinally-oriented, and generally circular-shaped throughbore is not substantially equal to the diameter of the light portion, so that the centrally-disposed, inwardly-tapering, longitudinally-oriented, and generally circular-shaped throughbore can be adjusted by the adjusting apparatus to properly fit on the light portion when the top cap of the light portion is removed and replaced by the voltage light novelty decoration.

A fail-safe, magnetically coupled head positioner latch assembly for a Winchester-type disk drive comprises a rotatably mounted latch member including an outwardly extending latch arm and tang, and a solenoid assembly. The latch arm is adapted for engaging the head positioner in a parked position, and rotating to a non-interactive position with the latch arm being non-interactive with the head positioner. Magnetic coupling force between a permanent magnet structure and the solenoid assembly causes the latch arm to remain in the non-interactive position during normal disk drive operation. Activation of the latch is accomplished by applying current to the solenoid which generates a magnetic field opposite to that of the permanent magnet structure causing the rotatably mounted latch assembly to rotate so that the latch arm engages the head positioner. The tang is adapted for interacting with a permanent magnet structure as the latch arm engages the head positioner, whereby the magnetic coupling force between the tang and the permanent magnet structure imparts a torquing force to the latch arm which restrains the head positioner in the parked position. Actuation of the head positioner upon initiating normal disk drive activity positively disengages the head positioner from the parked position.

A precision magnetic head positioner assembly for a Winchester-type hard disk drive storage system includes a main rotatable integral head positioner body and an integral magnetic coil assembly. The positioner body includes outwardly extending integral head positioning arms and a seating surface comprised of two angled lateral seating surfaces. The integral magnetic coil assembly comprises a coil frame and a mounting surface having two angled lateral mounting faces which engage the positioner angled seating surfaces for mounting with fasteners. Precision self-alignment of the positioner seating and bobbin mounting surfaces is provided by an alignment ledge protruding outwardly from the positioner seating surface which engages the lower edge of the bobbin mounting surface. An interference between the positioner seating surface and bobbin mounting surface angles improves mounting alignment and stability.

A stand for supporting the trunk of a tree in an easily adjustable attitude. A clamp can be securely attached to a lower portion of a tree trunk in such a manner that the clamp is immovable with respect to the trunk. A collar extends radially about the clamp and has a convex surface that has a downwardly-facing convex spherical surface and defines a central opening. A base includes a socket having a concave surface shaped to engage the convex surface of the collar matingly and with sufficient friction between the mating surfaces to hold the tree in any selected position with a generally upright attitude. The attitude and orientation of a tree held in the stand are easily adjusted by slightly lifting the collar to reduce the friction between the collar and the socket while rotating or tilting the collar with respect to the socket.
