Abstract: A vent for attachment to a housing wall with an aperture may include a body portion, an attachment mechanism via which the vent is attachable to the housing wall, a cover, and an antenna. The body portion may include a wall with an inner surface defining at least part of a central vent passage via which gas is passable through the vent. The cover may be arranged at a first axial end of the body portion covering the central vent passage. At least one opening may be disposed at a first axial end of the body portion for gas to exit the vent. The antenna may be attached to the inner surface of the wall of the body portion.

Abstract: A system and method for improved flow measurements for LCG, such as liquid petroleum gas (LPG), is disclosed. Embodiments of the present technology detect the presence of a vapor in a fluid flowing in a mass flow meter. A control valve is then adjusted to provide enough back pressure to prevent the measured liquid from flashing and to reduce the presence of vapor in the fluid flowing in the mass flow meter. By keeping the fluid in liquid form, the present technology reduces the vapor flowing in the mass flow meter, increasing the accuracy of mass flow and other measurements. Utilizing a similar principle of vapor detection, embodiments of the present technology provide for improved average parameter value calculation, such as average density calculations and equivalent liquid volume calculations.

Abstract: In the case of a known multiple-layer space-framing plate of rods and gusseted joints, which consists of a plurality of circular meshwork arrangements which are connected with one another, which extend as a honeycomb in a space, the circular meshworks define hollow spaces which are open to the outside, in the area of which no brackets are present for attachment of roofing or side wall coverings. Because of the dimensions of the openings on the top or the side walls of the space-framing plate, it is therefore not suitable for use in roof construction. The invention provides for a "cut out" or "design" of the space-framing plate in such a manner that in the hollow spaces which are open to the outside on the top and on the side walls of the space-framing plate which is to be cut to size, two-layer complementary space-framing elements can be incorporated in such a manner that on the top and on the side walls of the space-framing plate a screen of rods and gusseted joints is present, arranged in a plane.

Abstract: A microscratch-test method for measuring adhesion between a first material and a second material adhered to one another at an interface and forming an article. The method involves polishing a planar surface of the article generally normal to the interface and exposing the interface and the first and second materials. A static load of predetermined mass is applied to a starting point on the first or second material in a direction generally normal to the planar surface, using a load means of a third material harder than the first and second materials. The load means is moved across the planar surface from the starting point in a straight line generally toward and across the interface at an angle relative to the interface of between 90.degree. and about 20.degree.. These steps are repeated, varying the mass. The starting point for each repetition is spaced apart from other starting points but is approximately equidistant with other starting points from the interface.

Abstract: A mine tool roof bit insert geometry of a 30.degree. top relief angle between the top cutting edge and the top trailing edge and a radius of curvature of 1/16 inch at the corners improves the maximum wear and penetration rate when drilling into sandstone and a method therewith is described.
