Abstract: A drop down ladder rack is disclosed. The ladder rack has a first assembly and a second assembly configured to be mounted on top of a vehicle. The assemblies are coupled to a connecting rod, which is rotatable. The assemblies move between a first, raised position and a second, lowered position. Each of the first and second assemblies comprises a first support member fixedly secured to the vehicle, a second load carrying member configured to be slideably engaged with a first end of the first support member, and a third actuation member configured to enable the second load carrying member to move with respect to the first support member. A first end of the third actuation member is connected to the connecting rod by a drive rod and a second end of the third actuation member is pivotably connected to the second load carrying member, thereby enabling the second load carrying member to move with respect to the first support member.

Abstract: An arrangement for generating page and/or device-optimized cascading style sheets (“CSS”) is disclosed in which CSS blocks are provided in a collection of one or more files. In an illustrative example, the collection of files is arranged as XML (extensible Markup Language) files. Each CSS block is marked with attributes that indicate to which modules used to compose a page it applies, and/or its applicability to a specific device. At page rendering time, the CSS for the page is dynamically generated by selecting CSS blocks from the files based on detected device capabilities and/or the modules on the page.

Abstract: A support for manual grease guns has a base and lever-restoring mechanism. Grease guns conventionally have a pumping head with a barrel and lever joined thereto for cycling through pumping and restoring strokes between restored and depressed extremes. The restored extreme has the lever and barrel flared apart. Conversely, since the pumping stroke closes the flare, the depressed extreme has the lever brought alongside the barrel. The base has ground-engaging feet as well as clamps for clamping the grease gun tightly by the barrel, preferably with the lever projecting away for pedal-style depression in a generally vertical plane by a user stepping on it. The lever-restoring mechanism links the lever to the base, and yields under the user's step while the lever moves through pumping strokes, but restores the lever toward the restored extreme therefor as soon as the user takes his or her step off the lever.
