Abstract: A system and method for raising a structure, or part thereof, the system comprising vertical jack members connected and disposed about a rail system attached about the periphery of the structure. The vertical jack members comprise an outer sleeve and a slidable inner portion that is driven vertically by a jack screw and drive block. Extensible diagonal cross-braces stabilize the jack members and structure being raised.

Abstract: Disclosed herein are various systems and methods for controlling humidity in batteries to reduce formation of condensate in a battery compartment. In one embodiment, a system consistent with the present disclosure may include a cooling system configured to produce a flow of coolant. A battery compartment may house a battery and may separate the battery from an environment. The flow of coolant may pass into the battery compartment and may be used to cool the battery. The battery compartment may include a vent configured to permit a flow of environmental air to enter the battery compartment. A diffusion barrier may be in fluid communication with the vent and configured to deliver the flow of environment air to the battery compartment. The diffusion barrier may decrease diffusion of water vapor from the environment into the battery compartment.

Abstract: Described herein are various embodiments of a cold-weather garment. In one exemplary embodiment, a long-sleeve upper-body cold-weather garment includes a torso portion and two sleeve portions that are attached to and extend from opposite edges of the torso portion. The torso portion is made from a first material and the sleeve portions are each made from a second material. The first material is lighter per unit area and more breathable than the second material. The second material is heavier per unit area than the first material, but is more resistant to cold-weather environmental conditions. For example, the second material is water resistant, flame resistant and comprises an outer surface having a camouflage pattern.

Abstract: In a firefighter's protective garment, having a detachable outer flame-resistant shell and an inner thermal, i.e. heat, protective liner, the neck portion of the liner extending upright beyond an over-the-neck portion of the shell and fastening on the outside of the neck portion of the shell, such that the whole of the neck of a firefighter is protected by both a heat protective material and a fire protective material.

Abstract: An outer collar part is permanently secured to the shell body portion and to an inner collar part. A first moisture barrier is disposed adjacent the inner collar part, and a second moisture barrier is disposed between the first moisture barrier and the outer collar part. A third moisture barrier is disposed between the second moisture barrier and the outer collar part. A plurality of spaced lines of stitching connect the third moisture barrier with the outer collar part to form air pockets. A liner includes a thermal barrier and a liner moisture barrier. Cooperating hook and loop fastening portions are supported on the thermal barrier of the liner and the inner collar part to removably secure the thermal barrier to the inner collar part. Further cooperating hook and loop fastening portions are supported on the second moisture barrier and the liner moisture barrier to removably secure the liner moisture barrier to the second moisture barrier and the outer collar portion.

Abstract: An outer shell is stitched to an outer collar part which is in turn stitched to an inner collar part. A moisture barrier is stitched to and disposed between the inner and outer collar parts. A separate liner has an upper edge portion having fastening means thereon which cooperate with fastening means on the inner collar part and the moisture barrier for removably securing the upper edge portion of the liner to the inner collar part and the moisture barrier. The moisture barrier extends above and below the upper edge portion of the liner when the collar is in an upright position.

Abstract: A collar connection device is provided for use with a garment having a double-layer collar, the device having a first functional layer strip connected to sections of the garment by openable closures and a second functional layer strip also connected to sections of the garment by additional openable closures and where the two functional layer strips are attached in a line by a waterproof adhesive seam.

Abstract: A self-contained clothing system comprising a foundation garment, typefied by a shirt-jacket and a pant, and several removable components, typefied by a hood, a sleeved yoke, and two chaps, which, all together and in conjunction with normal undergarments, serve to protect the wearer from the elements in changing weather conditions. This versatility of function is achieved through a design which incorporates removable components, pockets to carry said removable components, adjustable ventilation openings, and the use of appropriate fabrics.

Abstract: A wet type survival suit, particularly useful for oil rig workers or pilots and crew members stranded in water, includes an outer layer of material including a sheet of breathing material sandwiched between layers of fire protection material, a middle layer of insulation material that provides flotation, and an inner layer of fire protection material. This arrangement protects against fire, allows perspiration to evaporate, and allows the user to float in water. Suit adjusting laces are provided to adjust the suit to a comfortable configuration for the user. Zippers close the suit to a tight fit for use in water and can be loosened to reduce the restriction when desired.

Abstract: A waterproof article for use in, for example, protective clothing. The article prevents liquid water from penetrating through to undergarments while at the same time permitting moisture vapor such as perspiration to pass out through the article. The article is thus both breathable and waterproof. The article is layered: a microporous hydrophobic outer layer which permits the passage of moisture vapor but resists penetration by liquid water at pressures up to about 345 Kn/m.sup.2 ; a hyrophilic inner layer permitting the transfer of moisture vapor but preventing surface tension lowering agents such as those contained in perspiration and/or body oils from reaching the hydrophobic layer.

Abstract: A protective collar for shielding the wearer against inclement weather which includes a strip of waterproof material having loop pile fasteners along the edges and the top thereof, the bottom edge of which is designed to attach to a windbreaker or other protective garment and the top loop pile edge to a helmet, protective hood, or hat.

Abstract: A multi-ply strip somewhat longer than the circumference of the average human neck has two oppositely-facing arcuate edge portions toward the center of the strip to accommodate the contours of the neck. In one form, the opposite short ends of the strip have angularly cut-off corner portions to facilitate detachment of the strip from a roll of strips.
