Abstract: A device and method for locking a firearm are provided, the device having a locking round, elongate locking rod, protective cylinder, and locking tool. The locking round has a radial flange, an internal thread, and a plurality of prongs associated therewith, wherein the prongs are disposed about a circumference of the locking round. The locking rod has a conical cam, an external thread, and a first engagement member, wherein the cam is operable to radially expand the prongs through engagement between the internal and external threads. A removable tool having a second engagement member is operable to be inserted into the protective cylinder that is rotatably coupled to the locking rod, wherein a rotation of the tool is operable to operable to engage the shoulder, prongs, and protective cylinder with the firearm, thus providing first, second, and third friction regions for locking the locking device in the firearm.

Abstract: A method for controlling mosquito populations comprising the following steps: a) providing an insecticide comprising a pyrethroid, b) providing a sprayer having an extension thereon, c) inserting the insecticide into the sprayer, d) inserting the extension into the catch basin, e) spraying the insecticide onto the interior surfaces of the catch basin, including any stagnant water which may be located at the drop-off of the catch basin.

Abstract: A method of making a carbon commutator is provided. The method includes the steps of providing a planar substrate having a series of current-carrying regions; providing a carbon base having a brush-contacting surface and a second opposite surface; substantially covering the second surface of the carbon base with a conductive plating to form an unslotted commutator body; applying a conductive bonding layer to the conductive plating; bonding the unslotted commutator body to the substrate; and cutting corresponding slots in the commutator body to form a series of commutator segments.

Abstract: A fuel pump and the method for making the fuel pump designed for operation in an environment of a hydrocarbon fuel having a significant portion of oxygen-containing moieties are disclosed. The pump consists of a body, a shaft, a commutator, and brushes in contact with the commutator; the method of making the commutator comprises the steps of affixing a formed carbon article to a suitable substrate, machining the article to a commutator, and cutting slots into the commutator. In one embodiment, the method includes forming the carbon article directly on the substrate prior to the machining steps.
