Abstract: The invention relates to a security barrier apparatus. Some embodiments of the present invention may be used in conjunction with a previously existing security gate or perimeter and other embodiments may be used as stand-alone security barrier gate systems. The various embodiments of the security barrier apparatus comprise a passive security gate apparatus that is capable of withstanding the force of an object, such as a vehicle, of up to 1.1×106 ft-lb/s wherein the driver of the object is attempting to gain entrance through the security gate apparatus.

Abstract: An improved system for upgrading new and existing gates or barriers to provide improved crash barrier rating. This system comprises a reinforcing attachment to the gate or barrier and improved reinforced bollards with catch hooks to absorb the energy of impact. The reinforcing attachment is an arrangement of cable and structural members that provide for increased reinforcement by ensuring that the load is distributed on the cable to minimize the risk of breakthrough as a result of cable failure. The bollards have been improved by strengthening the catch hook attachments and adding reinforcement positioning elements to facilitate proper assembly.

Abstract: A reprographic marking device has two rolls, e.g., a pressure roll and a fuser roll, forming a nip. A drive motor moves the rolls in a continuous back and forth lateral motion to change the position of the rolls relative to a paper sheet passing through the nip portion.

Abstract: A print job processing method at least includes: providing processing attributes for particular print stock, including a predetermined fuser dwell time; establishing a print job, including the stock to be used for each page of the print job; for each page in the print job, selecting the appropriate subsystem containing the stock specified for the particular page; for each page in the print job, transferring image substance to each sheet to be printed, the placement of the image substance corresponding to an image to be duplicated on the page; matching the appropriate portion of the processing attributes to each subsystem; for each page, automatically fusing the image substance to the page according to the dwell time established by the processing attributes for the stock used for the page; and outputting processed pages.

Abstract: A vibration damper includes at least one damper mass and at least one bush bearing, the bush bearing having an inner supporting core surrounded with radial clearance by an outer supporting sleeve, a spring mass made of elastomer material that extends essentially radially and joins the supporting core and the supporting casing being arranged in the gap formed by the clearance. The damper mass has an essentially pot-shaped recess, in which the bush bearing is arranged, the supporting casing being pressed in an essentially airtight manner into the recess, and the hollow space delimited by the damper mass and the bush bearing being designed as a pneumatic spring.

Abstract: A non-retractable ball-point pen is disclosed which comprises an elongate ink cartridge, an elongate barrel having a longitudinal bore therethrough for receiving the cartridge and an end cap for tightly sealing one end of the elongate barrel and for engaging and retaining the cartridge in the barrel. The other end of the barrel has a polygonal cross-section with a diameter smaller than the writing tip of the cartridge. Hence, the walls of the barrel defining the polygonal cross-section frictionally grasp the writing tip and the non-engaging surfaces of these walls provide vent passageways in communication between the interior of the bore and the outside atmosphere for venting the cartridge.

Abstract: A retractable ball-point pen includes a housing comprising a barrel and cap, the latter being rotatable with respect to the former to control extension and retraction of a writing tube located within the housing. A ferrule which is pressfit into an opening at the non-writing end of the barrel serves as a mount for a guide bushing having an offset bore therein through which a writing tube extends. The cap rotates about the cylindrical surface presented by the bushing and a retaining ring which engages the inner wall of the cap prevents axial movement of the cap. A cam member which includes a helical cam surface is fixedly mounted in the cap and a spring biases writing tube against the cam surface so that rotation of the cap in first direction causes extension of the tube while rotation in the opposite direction causes retraction of the tube.
