Abstract: A latch for securing a cover or door to an enclosure provides a dust and water tight seal. The latch has a housing in which an activator is rotatably mounted. The latch housing has a depression formed in one of its surfaces. A gasket is designed to fin in the depression providing a seal between the activator and the housing. In the preferred embodiment the latch is a quarter-turn latch. The rotation of the latch is limited between a locked and unlocked position substantially 90.degree. apart.

Abstract: A match performance 0.22 caliber cartridge having improved accuracy provided as a result of being manufactured with an improved base wall construction, and a thinner, less dense, more uniform and more effectively located lubricant coating on the bullet as compared to the 0.22 caliber cartridges utilized heretofore in match competition; and as a result of a lubricant groove which is located most advantageously and is manufactured with an optimum depth.

Abstract: A latching apparatus includes a rack and pinion drive. A latch bar slide between a latched and unlatched position with ramped latching members mounted on the bar engaging complementary latching members. The latch connects to several types of latch actuators including a button actuator having rotation indicating means. The latch is also configured to connect to a keyed latch actuator and a push-button actuator.

Abstract: A cabinet has overlapping doors to cover a cabinet opening. The overlapping doors include sealing gaskets formed on interior surfaces of the doors. The doors are shaped for the gaskets of the doors to overlap and abut in sealing engagement upon closure of the doors.

Abstract: A non-toxic primer composition for center-fire cartridges which provides improved ballistic data and is void of metallic oxidizing compounds. It is comprised of a mixture of about 10-30% by weight of nitrocellulose and/or a double based propellant such as Hercules Fines, approximately 30-75% by weight of two percussion-sensitive compounds such as DDNP and tetracene, and approximately 10-30% by weight of calcium silicide. The mixture provides improved propellant ignition and non-toxic ignition products, and minimizes misfires in that it contains no hygroscopic compounds.

Abstract: The invention comprises a washer for establishing electrical continuity between two conductive members each having a non-conductive coating and which are secured together by threaded fasteners such as screws. The washer has projections that pierce the non-conductive coatings of the two conductive components as the threaded fasteners are tightened thereby establishing electrical continuity through the washer.

Abstract: A restructurable enclosure having a plurality of mounting blocks which are secured to the body of the enclosure at various spaced locations around and adjacent the outer peripheral portions of the door and wall panel openings therein. Each of the mounting blocks includes a plurality of threaded bores in the bottom surface thereof which communicate with openings in the enclosure body to facilitate permanent mounting of such blocks to the enclosure, and to facilitate attachment of sub-panels and other assemblies within the interior thereof, without obstructing the same. Each block also includes a pair of threaded or open bores extending inward from its outer mounting surface to facilitate mounting of the enclosure door or various wall panels to the enclosure solely from the exterior of the enclosure, without the need for accessing the interior thereof.

Abstract: A multifaceted modular enclosure frame which is constructed of a latticework of identical cross-sectionally configured frame sections that include an inherent integrally formed guide system for proper installation and positioning of sub-panel mounting boards within the enclosure. Each frame section defines an interiorly disposed guide channel and mounting flange, an exteriorly disposed corner flange, and an exteriorly disposed flange trough, while maintaining an open design and a cross-sectional configuration which mates cooperatively with other identically configured frame sections to provide an integral mitered corner which is devoid of separate corner adapter inserts. The interiorly disposed guide channel provides the integral guide system for the sub-panel mounting boards which are received within the enclosure. Each corner flange defined by such frame sections provides an exterior surface upon which mounting blocks are carried to provide for complete external connection of enclosure wall panels thereto.

Abstract: A system for installing and properly positioning a sub-panel mounting board within a freestanding electrical enclosure, wherein the base sections of the enclosure frame form a continuous rectangular guide channel around the inner periphery of the enclosure which is designed to receive in opposite parallel channel segments thereof a pair of channel followers that are connected to opposite lower corners of the mounting board. Each channel follower has a depending leg which extends into its respective channel segment and supports the mounting board during installation thereof. The depending leg of each channel follower engages the bottom of the channel when the mounting board is tilted forward for installation within the enclosure. Once the mounting board is installed and positioned upright, each channel follower rests upon a mounting flange formed by the enclosure frame, thereby allowing the mounting board to be secured thereto.

Abstract: An electrical enclosure is shown having a cabinet and a door connected by hinges. The hinges comprise door and cabinet components and a removable hinge pin wherein the door component extends through a slot formed in a flange along an edge of the door, and the cabinet component is attached to the cabinet. Locking ramps are provided on the door component which extend through and engage the edges of openings in the door flange on opposite sides of the slot.

Abstract: An improved sabot bullet for use primarily in connection with shotgun shells which includes a slug having a forward portion which radially converges towards the middle portion thereof, and an outer conforming sabot casing which includes a pair of sabot segments which substantially surround and conform to the outer configuration of the slug. Each sabot segment is constructed to be slightly radially spaced from the slug near the constricted middle portion thereof, and to converge and engage the radially diverging portion of the slug near the forward end thereof, so as to cause the slug to be guided mainly at a point adjacent the front end thereof. Each sabot segment is also constructed to extend rearwardly beyond the rear end of the slug to facilitate rearward movement of the slug relative to the sabot, and consequent outward radial wedging of the sabot segments against the inner walls of the gun barrel, upon firing the fireman.

Abstract: A multiple point latching system, for use with single or multi-door enclosures, which utilizes a plurality of combinational cam-pinion latch members which are rotatably mounted to the inside surface of the door and simultaneously driven by an elongated rack which extends between such latches and disconnectedly inter-engages therewith. Each combinational cam-pinion latch includes a plurality of teeth which disconnectedly inter-engage with apertures in the rack to cause simultaneous rotation thereof. A handle which is connected to the door and accessible from the exterior thereof drives one of the latch members which in turn causes movement of the rack and consequent rotation of all other combinational cam-pinion latches. Such latches are rotatably mounted at spaced locations along the free peripheral portions of the enclosure door.

Abstract: A readily detachable fastener for mounting upon an enclosure, the fastener having a base member with channeled edge portions designed to slidably engage the enclosure upon which it is mounted. A connector pin extends outwardly from the base member, and is designed to releasably lock into a pin receiving hole of the enclosure such that the detachable fastener may be attached or removed from the enclosure, as desired. A latch is pivotally connected to the base member, and carries a bail which catches on the cover of the enclosure when the latch is pivoted to an open position. The latch may then be pivoted to a closed position, thereby tightly securing the cover to the enclosure. The base member and latch are constructed with openings therethrough so as to accommodate locking the same together with a conventional lock.
