Abstract:
One aspect of the present invention is directed to a door, and more specifically, to a door that includes a web and a rigid foamed core. In one embodiment, a door is disclosed which comprises a door shell having a generally planar construction with marginal edges and first and second door skins helping to define an interior door cavity, a web disposed within the interior door cavity, and a rigid foamed cementitious core disposed within the interior door cavity and cooperating with the web.
Abstract:
One aspect of the present invention pertains to an apparatus for forming a rigid foamed cementitious core within a plurality of article shells. In general, the apparatus can be comprised of a shell bank for retaining a plurality of article shells and comprising a sled and a plurality of reinforcement shells, a filing station for delivering a gas-entrained cementitious material, and a pump. The gas entrained cementitious material cures to form a rigid foamed cementitious core within each article shell in the plurality of article shells.
Abstract:
Drill stem elements and connections are shown with advantages such as being mechanically robust. The absence of a side access window in a sonde housing is one design feature that provides robust mechanical properties. Further advantages of the sonde housings include being easy to disassemble for access to the sonde unit, or for insertion of the sonde unit. In one embodiment, a cap portion is easily secured or removed using a small allen wrench, or a hammer and a punch. The cap portion is not substantially affected or tightened by rotation of the drill stem during a drilling operation. A further advantage includes the ability to remove cap portions and pull back flexible product such as polyethylene pipe from a small exit pit.
Abstract:
A high performance (10) door comprising a door shell (14) having a generally planner construction with marginal edges and at least one door skin (18) helping to define an interior door cavity (16) is disclosed. The door member is preferably constructed of a gas-entrained cementitious material and has a compressive strength of at least about 30 Ibf/in 2 when measured using ASTM C-39. A method for forming a door member for use in construction with the door generally comprising: providing a door shell (14) placing the shell (149 in a fixture, filling the interior door cavity (16) with a gas-entrained cementitious material, green-strength curing the gas-entrained cementitious material, and removing the door shell (14) from the fixture is disclosed. The cured gas-entrained cementitious material provides a gas-entrained cementitious core for use in conjunction with a door.

Abstract:
A drill stem connection system and method is shown that provides a secure hold on drill stem surfaces while unscrewing a threaded connection. Two lever arm components are adjustable to a number of possible orientations to allow for fitting the drill stem wrench in tight spaces. Concentric rotation of lever arm components facilitates connection of the lever arm components together. Configurations and methods shown provide a stable and powerful tool to loosen threaded drill stem effectively.

Abstract:
An improved cable pulling device and method is shown. The cable pulling device is smaller, less expensive, and easy to use for lateral line replacement. The cable pulling device includes a cable contacting portion that provides supplemental frictional force during a rotational pulling stroke. Among other advantages, this allows a smaller, more compact design that provides higher gripping and pulling power. Embodiments as described above further allow for a smooth jaw configuration that reduces cable damage. A cable pulling device is also shown that includes a configuration of a force distributing device. One embodiment includes substantially orthogonal plates that help to reduce device twisting during a pulling operation. In a further embodiment, a force distributing device is adapted for attachment to a ground working implement arm.
Abstract:
One aspect of the present invention includes a lite (14, 22) for a building structure. The lite (14, 22) comprises a first peripheral caming framework (56) and a first glass unit supported within the first peripheral caming framework (56). The first glass unit comprises a plurality of glass members (60, 64) and a second caming framework (58) supporting the glass members (60, 64). The glass members (60, 64) comprise at least one slump glass member (60).
