摘要:
Layered security bars (2, 4, 6, 8) are provided each having a structural outermost layer (10) and at least one ceramic layer (12) usually surrounding a core (14) to defeat attacks by thieves' tools. The outermost layer (10) is formed of a structural metal ordinarily an elongated tube (18, 36, 56, 72) having a case-hardened exterior (22) and a hollow interior (20, 28, 60, 74) containing discreet ceramic links (26). The embodiments include a simple bar (2), a deluxe prison bar (4), a rodded bar (6) with ceramic rod segments (68), and a shackle (8) with fish-spline links (78). Additional metallic and ceramic layered components are also provided.

A locking system for beverage taps (10) is provided for use with conventional beverage faucets (12) such as those utilized to dispense kegged beer and the like. The system (10) incorporates an elongated valve stem (14) which protrudes from the proximal end (38) of the faucet body (12) and is provided with an axial end bore (66) having pin threads (68) therein. A lock subassembly (18) actuated by a key (20) attaches to the valve stem (14) by a threaded driver pin (118) which engages the pin threads (66). A case cylinder (80) encloses the engagement position and overlaps a portion of the faucet body (12) such that antirotation ears (113) prevent relative rotation and loosening of the engagement except when the key (20) is utilized. When tightened, the lock subassembly (18) forces the valve stem (14) into a closed position, preventing opening of the faucet and dispensing of beverages.
摘要:
A portable tool for forming louvers in a sheet metal work piece. The tool has a substantially C-shaped frame with an upper leg, a lower leg, and a body forming a throat in which the louvers are formed. A female die assembly is mounted on the lower leg of the frame. A male die is positioned in a carriage which slides longitudinally along the upper leg of the frame. Stops define the length of travel of the carriage and clamps hold the work piece between the female die assembly and the male die. An increasing cutting and forming force is applied to the male die, and against the work piece and the female die assembly, until a louver is cut and formed in the work piece.

摘要:
A combination charging unit and portable, hand-held transceiver which includes a latch mechanism operable to effect an electrical connection between the charging circuit in the charging unit and the rechargeable power supply in the transceiver automatically upon insertion of the transceiver into the charging unit. The latch mechanism causes insertion of plug connectors on the charging unit into mating connectors in the transceiver in a direction which is perpendicular to the axis of insertion of the transceiver into the charging unit. The latch mechanism prevents damage to the plug connectors by exerting a predetermined constant insertion force, independent of the force employed to seat the transceiver into the charging unit, in mating the plug connectors. The latch mechanism includes a release lever which provides a mechanical advantage to the operator during the initial portion of its release movement thus compensating for the gripping effect of the plugs with their mating connectors.
摘要:
A tamper resistant bicycle lock (10) is provided having a base (12) and a shackle (14) each provided with an interior ceramic layers to defeat attacks by thieves' tools. The shackle (14) is formed of a structural metal tube (32) having a case-hardened exterior (34) and a hollow interior (46) containing ceramic links (36). The arc segment (22) of the shackle includes fish-spline links (40) and is bent into shape subsequent to the installation of the ceramic links (40). The base (12) is formed of an elongated hollow bar (70) with ceramic rod segments (96) in corner bores (94). A lock cylinder subsystem (112) is situated in central bore (84) and is provided with a cylinder guard subsystem (114) including metallic (138) and ceramic disks (140). Additional metallic and ceramic layered components are also provided.

Padlock structures in the form of a trailer lock (10) and base and shackle padlocks (124, 168) are provided. Each type of padlock includes a lock body/base (12, 126, 168) and a lock pin (42) or shackle (128). At least the lock body (12) and/or base (126, 158) is a structural metallic material and each is provided with ceramic interior elements (22, 24, 112, 116, 120, 166, 174) to, in combination, defeat or severely hinder directional attacks by thieves' tools. In deluxe embodiments a cylinder guard structure (90, 152) with alternating metallic wafers (94, 98, 108) and ceramic wafers (96, 106) protects the lock cylinder (66). Deluxe metallic lock pins (42) and shackles (128) are also provides with interior ceramic plugs (22, 24) often with interior flexible cables or capillary tubes (26) with marking fluids (28) to mark and identify perpetrators of tampering.
摘要:
A mobile radio programmed to analyze idle channel assignments issued by a repeater station and select different channels, if appropriate, which are especially adapted for communicating with other communication facilities, such as a telephone interconnect. Programmed into the mobile radio with each communication channel is an indication of whether or not such channel can be utilized to communicate with the other communication facility. If communications are desired with the other communication facility, and if the present idle channel assigned by the repeater station does not permit such communication, then a processor in the mobile radio consults a data list of appropriate channels, selects one such channel, and then establishes communications to the other communication facility on such channel.
