Abstract: A door security apparatus is disclosed herein. The door security apparatus comprises a sleeve member, a door engagement member and a spacer, and is configured to engage a double-lever arm door closer to allow for the locking of a door from the inside. The apparatus further comprises a locking mechanism for keeping the apparatus attached to the door closer. The door engagement member is configured to engage the top edge of a door, the sleeve member is configured to slidably engage the double-lever arm door closer, and the spacer is configured to connect the door engagement member and the sleeve member.

Abstract: Apparatus and method for adjusting and maintaining printhead-to-platen spacing in a printing device, wherein the printing device includes a printhead-carrying carriage and the carriage is pivotally mounted on and reciprocally shiftable along a guide shaft. An anti-rotation rail mounted on a hanger in the printer engages the carriage and determines its position relative to the printer's platen. A clamp structure is connected to the anti-rotation rail and extends through the hanger and is operable for clamping the anti-rotation rail to the hanger. An adjuster mechanism connected to the clamp structure is operable for selectively shifting the anti-rotation rail vertically upwardly or downwardly to position and maintain the carriage, and correspondingly, the printhead a preselected, nominal distance from the platen.
