A loading frame for fiber reinforced polymer (FRP)-concrete bond tests includes a standing guide tower, a base section, and a loading beam. The standing guide tower is perpendicularly mounted to the base section. A testing load is applied to the loading beam when performing a series of FRP-concrete bond tests. A sliding end of the loading beam is positioned into a channel within the standing guide tower allowing the loading beam to be positioned at a preferred height. The engagement between the loading beam and the standing guide tower reduces secondary forces. The loading frame is mobile and may also be used with existing testing devices and systems used to perform the series of FRP-concrete bond tests.

An indentation tester and indentation method for testing a sample heated at a temperature range from above 800? C. to 1200? C., and above, is disclosed. The indentation tester includes a stage having a metallic cylindrical base that houses an inner cylindrical base made of a temperature resistant material sufficient to maintain shape over the range of the heating temperature. A removable crown fastens to the cylindrical base and includes a ring that holds an axisymmetric pipe made of a temperature resistant material sufficient to maintain shape over the range of heated temperature. A nut is turned to tighten the pipe which secures the sample and guides an indenter to penetrate the sample. The indenter includes a rod made of temperature resistant material and a indenter tip.

An impregnation test apparatus includes: (1) a main body portion including a stage part having a recessed part in which an object to be impregnated is mounted, a bottom part of the recessed part provided with a plurality of through holes, an upper lid part mounted on the stage part, the upper lid part provided with a plurality of through holes in a parallel direction to the through holes, and a hollow part formed therein by mounting the upper lid part on the stage part, (2) an impregnation liquid supply portion connected to the main body portion and supplying the impregnation liquid to the hollow part of the main body portion through the through hole formed in the stage part, and (3) a fixing mechanism fixing the object to be impregnated mounted on the stage part into the hollow part by mounting the upper lid part on the stage part.

A compression test fixture including a first specimen engagement member having a first channel, the first channel having a first depth; a second specimen engagement member having a second channel having a second depth that is different than the first depth; and at least one coupling member engaged to both the first specimen engagement member and the second specimen engagement member such that a gap is defined between the first specimen engagement member and the second specimen engagement member, where the first channel and the second channel support the test specimen within the gap such that at least one opposing major surface of the test specimen is visible within the gap.

We disclose a toilet system which analyzes solid waste to detect tags which were associated with pharmaceutical or nutritional products and excreted in the solid waste of a user. The toilet system may include a receptacle for receiving solid waste, a liquid dispenser for providing a liquid to assist in dispersing the solid waste, a solid waste dispersing system which may mix the solid waste with the liquid thereby homogenizing the solid waste, and an electromagnetic signature detector which may analyze the tags in the solid waste. The electromagnetic signature detector may include a selective binding surface which may bind tags present in the solid waste and which may be connected to a transducer which senses the presence of bound tags.

A system and a method for detecting aromatic compounds mixed with aliphatic compounds are provided. As exemplary system includes a lower substrate including a magnet and a magnetic film comprising a magnetic particle filler in a polymer matrix disposed over the lower substrate. An upper substrate is disposed over the magnetic film wherein the upper substrate includes an opening extending to the magnetic film.

The present disclosure relates to a material testing system for use in testing material strength of various gas turbine engine components. The material testing system provides a load force onto portions of gas turbine engine components.

A method for determining a shear property of a sample includes supporting a sample at three or more separate support locations about a periphery of a first surface of the sample in a testing fixture, the sample including a second surface separated from the first surface by a thickness, wherein the sample is axisymmetric about an axis that is orthogonal to the first surface. The method includes applying a load on the second surface of the sample with a load applicator in a direction substantially parallel with the axis, measuring, with a controller, shear testing data of the sample in response to applying the load, and determining, with the controller, a shear property of the sample from the measured shear testing data.
