Patent CA-2439316-A1 (CA)
Inventor: O'BRIEN RICHARD
IPC: G01N29/02
Filed: 2002-02-26
Abstract: An apparatus for making pulsed acoustic measurements to determine particle size in a sample (1) such as a colloid. The apparatus includes two elctrodes (2) between which an electric voltage is applied to the sample. The voltage is applied in short pulses. The applied voltage generates an acoustic signal, such as a sound wave (5), in the sample which is detected with a transducer (3) after the wave (5) has passed through a delay element (4). The delay element (4) is used to introduce enough of a time delay between the application of the voltage pulse and sound wave (5) reaching the transducer so that the received wave's signal can be isolated from any signal generated in the transducer (3) by the applied voltage. The delay element (4) and the transducer (3) are arranged into a geometry, or, alternatively, the delay element (4) is shaped, so that any reflections of the sound wave (5) from the sidewalls of the delay element (4) are deflected away from the transducer (3).  This reduces interference, particularly at low frequencies.

Title: Building blocks with integrated assembling design
Inventor: GAGNE LOUIS
IPC: E04B2/06
Filed: 2003-10-24
Abstract: A building material made of chopped straw, Portland cement, mortar cement or lime combined together with a bonding agent is pressed into building blocks of different sizes and shapes. The blocks come in different sizes and shapes to serve different building needs and/or to fit an integrated assembling system. The blocks are interlocked or joined to correspond to specific requirements. Depending on the proportions of the ingredients and the pressure exerted to make the blocks, the density can be controlled to increase either the insulation value or the structural value. The grooves, which are part of the interlocking system, can also be filled with concrete either vertically or horizontally or both to create a stronger structure calibrated according to additional structural needs. The resulting concrete structure can also be reinforced with steel rod to further increase its strength. This building material is highly adaptable and environmentally friendly.
