Abstract: A lubricant composition for ammunition is an admixture of (a) molybdenum disulfide, (b) a fluorotelomer lubricant, and (c) a solvent medium which is deposited onto (d) a corn cob particle absorbent. Metal particles such as BBs or other grit may be included in the composition for use with copper jacketed bullets. The lubricant composition is deposited on the bullets by tumbling or vibrating the bullets, or otherwise contacting the bullets with the lubricant composition; drying the bullets and, thereafter contacting the bullets with untreated corn cob particle.

Abstract: A fire-extinguishing, material-containing, launching apparatus has a bore in which a projecting or launching wall releasably seats a canister of fire-extinguishing material. The apparatus includes a hollow tube which is disposed the launching wall and biasing member such as a spring, which normally urges the wall toward an open end of the tube. The wall is restrained from movement through an actuator rod, the forward end of which defines a retention member. Guide slots provided in the tube limit the movement of the launching wall.

Abstract: A method for mounting elongated pin connectors 10 which have a connector body 11 and pin contact elements 5, wherein the pin contact elements are pressed, preferably in a single operation, into openings 7 of a circuit board 8 and into openings 90 of body 11 arranged below circuit board 8. A pressing tool 1 is provided for contact element combs 2 which have a pilot strip 6 to which contact elements 5 are attached. A clamping section 3 of the tool 1 is designed so that it severs pilot strip 6 when the contact elements are pressed into contact with circuit board 8. The connector body 11 has cams 93,94 adjacent slots 90 for forming an upper surface with their upper sides.

Abstract: One piece socket (1) or pin type (37) electrical contacts are stamped from a sheet of resilient, electrically conductive material and rolled into a tubular body (3) having a center section (11, 39) of enlarged diameter which functions as a C spring and is radially compressed to insert or remove the contact from either the front or rear of a bore (33, 41) in a connector (31, 45). An annular groove (17, 47) in the center section (11, 39) engages a retention ring (35, 49) in the bore (33, 41) to lock the contact (1, 37) in place and the center section (11, 39) bears against the wall of the bore (33, 41) to stabilize the connection. The resilient fingers (19) forming the socket type contact (1) taper inward and then flare outward to form a funnel (21) which guides the pin (53) of a mating pin type contact (37) into a narrow neck (55) in the socket where it is wiped clean and firmly gripped.

Abstract: An improved electrical contact (10) for an electrical connector is disclosed. A first version of the contact comprises an elongated deep-drawn holder (11) having an axial holder passage (14) and an enlarged shoulder (12). The contact also includes a plurality of axially aligned electrical conducting fine wires (50) assembled together in a brush wire bundle. An elongated deep-drawn sleeve member (40) having an axial passage (46) extending therethrough is positioned over the holder to transform the first version into a second version of the contact. An intermediate flange (20) of the holder disposed rearward the shoulder is bent radially inwardly from the inner surface (22) of the holder passage to a position immediately adjacent the opposite inner surface (24) of the holder passage to provide an aperture (30) rearward the flange. The wire bundle, the sleeve and the holder are crimped together at a position forward the shoulder by four dies (64, 66, 68, 70) spaced apart in a circular arrangement.

Abstract: A filter connector is disclosed with an adaptor member (14) which permits removal and replacement of the filter connector member (10) without individually disconnecting and reconnecting the wires (16). The filter connector member (10) is provided with a plurality of filter contacts (22) each having a mating end (pin 26) at the forward end and a mating end (pin 28) at the rear end. A filterless connector member (12) includes plural filterless contacts each having a wire receiving end (74) and a mating end (socket 72) adapted to mate with the pin (26) of the corresponding filter contact (22). An adaptor member (14) includes a plurality of filterless contacts (42) each having a wire receiving end (90) and having a mating end (socket 88) adapted to mate with the pin (28). The filterless contacts (42) in the adaptor (14) are individually removable and replaceable in the event of a malfunction in these contacts.

Abstract: An electrical connector assembly, wherein contacts contained therein are shielded from electromagnetic interference. A coupling nut 300 unites a first metal shell 100 having a flange 140 thereabout, with the flange 140 having a first groove 180 formed in the face thereof, and a cooperating groove 190 formed about the periphery of the front section of the shell 100, and a second metal shell 200 having an end wall 220. A metal to metal contact is assured between the flange 140 of the first shell 100 and the end wall 220 of the second shell by means of a resilient metal strap 500 positioned with said grooves, with the leg portion 510 in first groove 180 in contact with the end wall 220 and the stem portion 520 situated in cooperating groove 190 contacting the front section of the first shell 100 and front section of the second shell 200. The strap 500 is preferably formed with grooves 530 therein, adjacent grooves 530 extending from opposite sides of the strap to give the strap 500 a sinuous shape.

Abstract: An electrical contact (10) for an electrical connector including a sleeve (20) and a plurality of axially-aligned fine wires (30), with each wire having an acutely angled end portion (32) at one end thereof and with the plurality of wires secured together at the other end to form a bundle (40). Preferably, the wires are secured together by a weld (50) formed by a capacitor (210) discharging across a gap (300) to the wires, although other securing methods could be used. The bundle (40) of wires then may be inserted into the sleeve of the contact (10) with the angled ends (32) forward in the sleeve (20) and the weld (50) rearward in the sleeve. Said sleeve then is crimped inwardly (25) forward of, or including, the welded portion, to hold the bundle (40) in place within the sleeve.

Abstract: An electrical connector is disclosed with a coupling nut (14) of the bayonet type for the connector bodies (10, 12) and an improved locking means (16) for the coupling nut. A resilient detent element (82) is disposed in a bayonet ramp groove (54) of the coupling nut (14) so as to be deflected and engaged by the corresponding bayonet pin (32) on one of the connector bodies when the coupling nut is tightened sufficiently to draw the connector bodies into abutting relationship.

Abstract: A solder pack consists of a thin heat resistant carrier board having spaced holes therethrough in which are held solder rings. The solder pack is, for example, placed over pins supported in correspondingly spaced holes in a printed circuit board so that each pin protrudes through an associated solder ring in the solder pack. Heat is applied to melt the solder rings to solder the pins to the printed circuit board. Two representative means for manufacturing solder packs are disclosed.
