Abstract: A clamp for an inline connector having a male and a female component comprises a first sleeve having a peripheral portion defining an opening for receiving and holding the male or female component. A second sleeve is provided adjacent the first sleeve and has an opening therein which is adjacent the opening in the first sleeve. A handle having a first end is pivotally connected to the first sleeve for rotation about the pivotal connection. A bracket is pivotally connected to the second sleeve member at one end thereof and pivotally connected to the handle at another end thereof. Rotation of the handle about its pivotal connection to the first sleeve moves the first sleeve and the second sleeve relative to each other between a first position where the first sleeve and the second sleeve are closer to each other and a second position where the first sleeve and the second sleeve are further apart from each other.

Abstract: An aircraft medical unit comprises a front panel configured to fit in an aircraft cabin so as to form a divider inside the cabin and a spaced rear panel of substantially the same shape as that of the front panel. A side panel is constructed between the front and rear panels, and the front, rear and side panels defines a chamber. An access opening is formed in the front panel. A stretcher frame is provided and is movable between a folded and stowed position in the chamber and an unfolded and extended position to the outside of the chamber. The aircraft medical unit further includes at least one item of medical equipment used in the treatment of a patient.

Abstract: A bracket for mounting a motorcycle foot platform on a motorcycle frame comprises a mounting body having a fastening mechanism for fastening the bracket to a frame of the motorcycle, and a connecting portion. A support arm supports the foot platform, and has a central portion which connects to the connecting portion of the mounting body. The support arm has a front arm portion extending substantially forwardly from the central portion and has an end remote from the central portion and an attachment member near the end for receiving and attaching to the foot platform. The support arm also has a back arm portion extending substantially rearwardly from the central portion and has an end remote from the central portion and an attachment member near the end for receiving and attaching to the foot platform.

Abstract: An acoustic-to-electrical transducer for sensing body sounds is provided. The transducer comprises a diaphragm that can be placed in direct contact with a body, whereby the diaphragm motion directly affects an electromagnetic sensing signal, which is then converted to an electrical signal representation of the diaphragm motion. Such sensing means allows the diaphragm to move freely without mechanical coupling to a secondary transducer, while providing a direct and efficient acoustic to electrical conversion means. The transducer further provides a means for using static diaphragm pressure to control gain and frequency characteristics of the electrical signal. The sensor, circuitry, manufacturing methods and improvements are provided.

Abstract: A visually enhanced teaching text comprises a series of words to be sung, the series of words having a plurality of tropes each having a predetermined tune. The text also includes symbols in the text indicative of the start and end of a trope, with at least some of the tropes being associated with a particular distinctive color so that each trope in the series of words is clearly distinguishable from surrounding tropes therein. The invention is also for a singing teaching method using color coded backgrounds.

Abstract: A filter device for removing combustion gases and/or particulate matter from air comprises a cooling unit and filtering unit. The cooling unit has an inlet for receiving an air stream containing combustion gases and/or particulate matter, a cooling member for lowering the temperature of the air stream, a first outlet for discharge of a condensate, and a second outlet for discharge of the air stream containing uncondensed particulate matter. The filtering unit has an inlet for receiving the air stream containing uncondensed particulate matter from the second outlet of the cooling unit, the filtering unit having at least one filter barrier through which the air stream passes, the filter barrier being configured to catch at least a portion of the particulate matter in the air stream. The invention is also for a process for removing combustion gases and/or particulate matter from an air stream.

Abstract: A mitred grate and drain cover comprises a peripheral edge having an upper and lower surface and a substantially elliptical shape which defines a space, and a plurality of cross pieces within the space. Depending sidewalls extend from the lower surface of the peripheral edge, and are constructed with respect to the peripheral edge such that they are at an angle other than 90° to the peripheral edge. The sidewalls define a space for receiving a pipe.

Abstract: The invention is for a method for removing at least a portion of a floorboard from a plurality of floorboards installed on a surface base. The method comprises isolating the floorboard or portion thereof for removal and removing a central portion of the isolated floorboard so as to leave a pair of elongate lateral strips, a pair of end portions and a substantially central open space. A routing bit having a shaft and a blade portion is then located such that the blade portion is parallel to, and cuts in, the same plane as the surface base on which the floorboard is installed. The blade is placed beneath the lateral strips and/or end portions so as to remove all material between a lower surface of the floorboard and the base upon which it is installed. The invention is also for a routing bit for removing a floorboard from the base upon which it is mounted.

Abstract: A hydraulic power generation system is provided for generating power using a pseudo-osmosis process which efficiently exploits the osmotic energy potential between two bodies of water having different salinity concentrations. The method and apparatus of the present invention does not require the use of a semi-permeable membrane or other specially formulated material, nor does it require heating or cooling of the fresh water or salt water solution. Moreover, the device may be used to recover energy from a wide variety of fresh water sources, including treated or untreated river run-off, treated waste-water run-off or effluent, storm-drain run-off, partly contaminated fresh water run-off, and a wide variety of other fresh water sources. The device is well suited to power production in a wide variety of geographic locations and under a wide variety of conditions.

Abstract: A gas accumulator is provided for attachment to a gun having a gun body, a compressed gas chamber in the gun body, and a compressed gas power source.
