Abstract: A component for a gas turbine engine, including: at least one internal cavity extending through the component, the internal cavity having at least one inlet opening and at least one outlet opening each being in fluid communication with the at least one internal cavity; a plurality of cooling features extending from a surface of the at least one internal cavity, the plurality of cooling features are formed in accordance with at least one of the following groups: i) a plurality of airfoil shaped features that extend upwardly from the surface of the at least one internal cavity and a plurality of wedge shaped features each having a triangular base that has an upstream portion and a downstream portion, the upstream portion extending further from the surface than the downstream portion; ii) a plurality features having a curved or “J” shaped base that extends upwardly from the surface, a plurality features having a double curved or symmetrically “J” shaped base that extends upwardly from the surface, and a pluralit

Abstract: A lightweight concrete composition containing from 10 to 90 volume percent of a cement composition, from 10 to 90 volume percent of particles having an average particle diameter of from 0.2 mm to 8 mm, a bulk density of from 0.03 g/cc to 0.64 g/cc, an aspect ratio of from 1 to 3, and from 0 to 50 volume percent of aggregate; where the sum of components used does not exceed 100 volume percent, and where after the lightweight concrete composition is set it has a compressive strength of at least 1700 psi as tested according to ASTM C39 after seven days. The concrete composition can be used to make concrete masonry units, construction panels, road beds and other articles.

Abstract: A lightweight cementitious composition containing from 10 to 90 volume percent of a cement composition, from 10 to 90 volume percent of particles having an average particle diameter of from 0.2 mm to 8 mm, a bulk density of from 0.03 g/cc to 0.64 g/cc, an aspect ratio of from 1 to 3, and from 10 to 50 volume percent of sand and/or other fine aggregate, where at least a portion of the sand and/or fine aggregate has a fineness modulus of less than 2; where the sum of components used does not exceed 100 volume percent, and where after the lightweight cementitious composition is set it has a compressive strength of at least 1700 psi as tested according to ASTM C39 after seven days. The cementitious composition can be used to make concrete masonry units, construction panels, road beds and other articles.

Abstract: A mail receptacle is disclosed in the form of a pouch which attaches to the periphery of a mail slot on the interior of a door or wall of a residence or building to receive mail therein which is inserted through the slot. Part or all of the pouch material is transparent to provide a visual indication of mail delivery. A zipper opening is provided in the pouch to retrieve delivered mail from the pouch. A flap is provided as extra protection against air drafts.

Abstract: A pain relief composition and method of preparing such for producing a therapeutic composition for topical application to the skin to provide symptomatic pain relief from a number of conditions such as arthritis. The pain relief composition is prepared from roots of the family of Burdock plants and in particular from at least one of the species Arctium lappa as Arctium minus in combination with roots of the Phytolacca family and in particular the species Phytolacca americana. The combination of roots are inserted into a receptacle containing water. The initial mixture is heated until boiling occurs and the mixture is continually boiled for a predetermined time interval until a coloration change of the substantially transparent water is seen to occur. There is formed a substantially darkened gray colored suspension which has found to include an extract of the combination of the Phytolacca and Burdock roots with some remaining extraneous bulk material.

Abstract: A system for monitoring the weight of a patient comprises a flexible but nonelastic envelope supported on a rigid support surface wherein said envelope has flexible upper and lower surfaces connected together in sealed relationship at spaced intervals forming a plurality of adjacent cells contiguous throughout the surface areas of said upper and lower surfaces. The envelope contains a fluid layer so that the pressure within the fluid layer is indicative of the total load supported on the receiving and supporting surface. A transducer responsive to the pressure of the fluid layer is provided for producing an electrical output indicative of the load supported on the receiving and supporting surface, and circuitry is coupled to the output of the transducer for selectively generating a visual readout indicative of the weight of a patient supported on the receiving and supporting surface and/or a change in the weight of the patient.
