Abstract: Apparatus and methods for cutting carpet pile are disclosed as including a clipper having a driver, a reciprocating blade and a fixed blade. The fixed blade and the reciprocating blade define an area there between. The fixed blade has a bore passing through the blade and into the area. A fluid supply, connected to the bore, supplies fluid through the fixed blade and into the area. A manifold, attached to the fixed blade, can be used to pass fluid through the fixed blade into the chamber. In such an embodiment, the manifold includes a passage communicating with the bore and the fluid supply. In another embodiment, an orientation mechanism is used to orient the carpet clipping head. In this embodiment, the orientation mechanism includes a base bracket and a pivot bracket. The pivot bracket is pivotally attached to the base bracket at a pivot point. The carpet clipping head is attached to the pivot bracket so that movement of the pivot bracket causes the carpet clipping head to pivot about the lead prong.

Abstract: A design is formed in a carpet secured to a table with a carriage controlled and moved over the table by a computer. A carver is mounted to the carriage and is computer-controlled to carve a design into the secured carpet. Also, a separator is mounted to the carriage and is computer-controlled to separate the carved carpet into a plurality of pieces. The secured carpet has a grain extending in a first particular direction, and carving in a second particular direction produces an actual result offset from an intended result by a quantified offset. The first direction and second directions are determined and a relationship therebetween is calculated. An offset associated with such relationship is then determined, and the determined offset is employed to position a carver during carving in the second direction. Thus, the employed offset produces an actual result that aligns with the intended result.

Abstract: An open cylinder adapted to receive a tear gas canister has a trigger mechanism that holds the canister well above the bottom of the cylinder. When the device is activated by an intruder, the operating mechanism withdraws trigger mechanism from under the cylinder, frees the cylinder to fall by gravity against an impact plate, which inturn, opens the canister value so that tear gas is discharged into the surrounding environment.
