Abstract: The present invention relates to a spring mattress comprising springs enclosed in casings, a so-called pocket mattress, and a method and a device for manufacturing such a mattress. The spring mattress according to the invention comprises a plurality of interconnected coil springs (1) enclosed in casings (2), for at least one of the springs, the casing portions arranged at the spring ends being moved towards each other, through the spring, and interconnected with the aid of connecting means.
Abstract: Coated metal peroxides, their preparation and use, in which metal peroxides are coated with silicone compounds from selected from the group siliconates, hydrogen-polysiloxanes, siloxanes, silicone resin emulsions, silane/siloxane emulsions, silane/siloxane mixtures, silicone microemulsion concentrates, and silicic acid ester mixtures.
Abstract: An environmental protection and detection system includes a vapor and gas impervious barrier extending beneath at least part of the area of an enclosure to prevent fluids leaked or spilled within the enclosure for flowing downwardly into the underlying soil and ground water and to prevent vapors and gases emanating from sources beneath the enclosure from percolating upwardly into the enclosure. Lengths of perforated pipe are positioned above the barrier and are connected to points outside the enclosure for use in detecting and removing contaminants leaked or spilled within the enclosure. Lengths of perforated pipe are positioned beneath the barrier and are vented to the atmosphere for preventing accumulations of fluids emanating from sources beneath the enclosure.
Abstract: A system for the selective deployment of a tire deflation device. The system incorporates the use of a mounted housing combined with a compressed gas propulsion source for ejecting a collapsed tire deflation device that is attached to the housing with a tether line. One embodiment of the invention is to have a dual system mounted to the underside of a vehicle behind the rear tires. Each system is pointed in an opposite direction to achieve left or right side deployment. A set of control switches mounted inside the vehicle near the operator can be depressed for either left or right side ejection. Upon ejection the tire deflation device projects laterally away from the vehicle. A remote trigger is disclosed.
Abstract: A method for strengthening a weak stratum using a solidified composition is provided. The method comprises the steps of: forming a horizontal drainage layer on the weak stratum; building-up mound structures on the drainage layer-formed weak stratum to the critical mound height; vertically forming holes in weak stratum; and mixing a first mixture comprising 25-35 parts by weight of cement, and on the basis of 100 parts by weight of the cement, 0.2-0.4 parts by weight of high fluid adjustment and 0.1-0.2 parts by weight of gel retardant, with a second mixture composed of 65-75 parts by weight of dried sand having a particle size of 0.074-5.0 mm, and on the basis of 100 parts by weight of the cement, 0.3-0.8 parts by weight of aluminum powder, then introducing the first and second mixture into the holes.
Abstract: A reusable mat system for the construction of load bearing surfaces, such as temporary roadways and equipment support surfaces, over unstable or unsubstantial terrain, comprising durable, interlocking individual mats which can be quickly and easily installed in a single application, and which can thereafter be easily removed and stored until needed again. The individual mats of the present invention interlock on all sides to form stable and continuous load bearing surfaces, and exhibit favorable traction characteristics.

Abstract: An apparatus for inserting and removing a flexible first material into a second material (20) includes a moveable carriage (22). An adjustable clamp (24) is connected to the moveable carriage (22), adjustable between an open position and a clamped position on the first flexible material. In a preferred embodiment, a receiver stiffener casing (26) is configured to receive and support the flexible first material as the flexible first material is inserted into and removed from the second material.
