Abstract: A slate and tile roofing system includes a base layer of compliant roofing material and a series of tile fasteners fixed along a top portion of the roofing material. A series of weather barrier strips is attached to the series of fasteners and fixed to the roofing material. A series of slate tiles is semi-permanently mounted over the weather barriers to form a prefabricated tile roofing subassembly. The subassembly expedites and facilitates the installation of slate and tile roofs without the need for highly specialized labor.

Abstract: A launch, recovery, and handling system includes a track system arranged on a deck of a ship and a stern door of the ship. The launch, recovery, and handling system also includes an aft cradle and a forward cradle that are connected to the track system and moveable in first and second directions along the track system. The aft cradle is moveable from a first position at a first area inside the ship to a second position on the stern door for at least one of launching and recovering a payload.

Abstract: An inflatable structure mount is used for mounting a device to an inflatable structure. An example is mounting of radar panels to an inflatable structure within an airship. The mount includes the device, and inserts coupled to the back side of the device, which mechanically couple to flexures mounted on the inflatable structure. Some of the flexures may have slotted holes, used in positioning the inserts on the inflatable structure at positions that will allow the flexures to mate with the inserts. A jig or tool may be used as part of the installation process, to locate the flexures at points where they will properly engage the inserts. The flexures may also each face a center point that is underneath the device to be mounted. The flexures may engage the inserts in ways that allow for quick installation and de-installation of devices, and may allow for visual inspection of proper installation.

Abstract: A cantilevered leaf spring is biased against the upper edge of a roofing tile to prevent the tile from sliding upward beneath an overlying upper row of roofing tiles. The leaf spring can be formed as a part of a tile fastener which includes a hooked portion for receiving and holding the lower edge of a roofing tile on a roof. A series of tile fasteners is mounted to a layer of roofing material to facilitate installation of tiles without the need for installation tools. Damaged tiles can be easily replaced without the need for installation or removal tools. With this system, each row of underlying tiles is locked in place by the combined effect of an overlying and overlapping row of tiles and a spring awl on an upper fastener pushing the upper edge of a tile downwardly so that the lower edge of the tile is forced into the mouth of a lower fastener.

Abstract: Lightweight tile roofs using a single overlap of tiles between adjacent tile courses are protected from wind, rain, snow, ice, humidity and sun with a base layer of water resistant weatherproofing material and with a series of waterproof or water resistant shield strips. The shield strips are laterally spaced apart so as to underlie the cracks, joints or channels formed between the adjacent side edges of each pair of juxtaposed tiles. This double layer of weatherproofing material extends the useful life of lightweight tile roofs.

Abstract: A roofing tile installation system includes spaced rows of installation strips each having an elongated base to which is attached a plurality of spaced apart hooks. The hooks are formed with a profile that engages and presses on underlying tiles and that grips and hooks around the lower edge of an overlying tile. Each tile is positioned and held laterally between a pair of hooks and held vertically on the slope of a roof by a single hook. An improved weatherproofing system includes a second layer of water resistive material which protects an underlying layer of plastic weatherproofing material against exposure to sunlight and erosion from wind and rain.

Abstract: The illustrative embodiment of the invention is a munitions canister having a cover that is impervious to a variety of environmental stresses. In the illustrative embodiment, the cover includes a layer of rubber, which overlies a layer of sectioned, impact-resistant foam, which overlies a dome-shaped, structural member, which overlies a layer of acoustical dampening foam.

Abstract: A field case housing has a substantially cylindrical wall segment, an end segment and a flange all having a substantially constant wall thickness. The flange has reinforcing ribs connected to the wall segment and aperture reinforcing bosses. The end segment, the wall segment and the flange are formed as a single, integral part adapted to reduce warping of the housing during molding. A cylindrical guide member is located in the field case housing and a conical guide member is located in the fan baffle. The cylindrical guide member is adapted to insure a screw passing through the cylindrical guide member is guided to a point within the conical guide member. The fan baffle has a transverse wall with an aperture and guide walls extending adjacent the aperture. The guide walls are adapted to guide an armature past the magnets without contacting and damaging them.

Abstract: A drill (10) has a housing (12) with a motor (14) which includes an output pinion (104) which defines an axis (102). A power source (16) is coupled with the motor (14). An activation device (44) energizes and deenergizes the motor (14). As the motor (14) is activated, an output (18), which is coupled with the motor (14) is driven. The output (18) defines an output axis (156) which is substantially perpendicular to the motor axis (102). A transmission (20) is coupled between the motor (14) and the output (18). The transmission (20) changes speed and torque of the output (18) between at least two different settings.

Abstract: An fire protection system for use in shipboard magazines wherein electric at detectors in a ship magazine provide temperature data to a fire panel. Upon detection of predetermined threshold temperatures, the fire panel initiates an alarm system and activates a fire sprinkler valve to apply water to fire sprinklers in the magazine. Temperature data from the heat sensors and stored weapon response data are used by a damage control system to generate graphic display data showing thermal conditions in the magazine and estimated times and temperatures at which stored munitions will undergo thermal destruction.

Abstract: A system for determining the time between the receipt of two different sils, includes a voltage ramp generator which generates a time dependent voltage signal upon receipt of a timing pulse at a time T.sub.1, and provides the instantaneous value of the voltage signal when the voltage ramp generator receives an input signal having a predetermined threshold value at time T.sub.2. A data processor coupled to receive the voltage signal, generates the timing pulse, and determines a time difference .DELTA.T from the voltage signal, where .DELTA.T=T.sub.2 -T.sub.1.

Abstract: A radar/laser speed detection countermeasure device for use on a motorcycle is disclosed which detects and annunciates radar and/or laser based speed detection devices in use in the immediate physical area for the purposes of speed limit law enforcement. The device consists of a main detector body mounted in an interior cavity of a motorcycle, which is electrically connected to a remote mounted sensing head unit and a remote mounted indication and control panel. Hidden components and interconnecting wiring reduce the chance of theft and preserve the appearance of customized motorcycles.
