Abstract: The breathing assistance apparatus of the present invention includes a manifold that is provided with or retrofittable to gases supply and humidifying devices. The manifold allows gases from an oxygen concentrator to be combined with the flow through a gases supply and humidifying device, most usually air. The combined output of oxygen and other breathing gases (air) is then humidified. The breathing assistance apparatus and manifold of the present invention provides a safe method to add oxygen to the input air stream of a gases supply and humidifying device and reduces the amount of accumulation of oxygen within the gases supply device, reducing fire risk should sparking occur within the device.

Abstract: Various implementations of a system that addresses the need for clean drinking water, improved solid fuel combustion and convection of the heat resulting from the combustion, exhausting of gases and air-borne particulates resulting from combustion, and provides electricity for lighting and charging of battery-operated devices are described herein. The system may include at least one solar panel, a battery, a fan assisted exhaust hood, a fan assisted cooking device, and a water purification device. Such a device could not only save millions of lives, but the quality of life for millions of people living in impoverished areas or refugee camps could be improved dramatically.

Abstract: An apparatus for decomposing kitchen waste by the use of vermiculture includes a container. A conduit is disposed along a bottom of the container and is attached to a spigot that exits from the container. A plurality of fluid collection openings are arranged in spaced-apart rows along a bottom of the conduit and in a cluster proximate the spigot. Gravel or other means for producing a volume for the collection of an effluent is provided along the bottom of the container up to the uppermost height of the conduit, which is sloped downward toward the spigot. A screen is placed over the conduit and gravel. A starter material is placed over the screen and provides a habitat for a preferred species of earthworm which are then added.

Abstract: A tensioning device has a tension arm mounted on a base. A pulley is mounted on the tension arm for engaging a looped belt. By changing mounting bushings, one can select either a static mode wherein the tension arm is held stationary relative to the base, or a dynamic mode wherein, in response to a changing force applied between the pulley and the belt (due to vibrations or load changes, for example), the tension arm moves relative to the base such in a manner as to maintain the force substantially constant. Several such devices can be employed in a system for controlling the tension of a looped belt, one or more of the devices being in the static mode and one or more being in the dynamic mode. Several such systems can be employed in a complex machine such as a photocopier or medical apparatus for controlling the tension in a number of different belts.

Abstract: A modelling system (1) comprises a blood vessel simulating model (2) connected to a pump system (3) and mounted in the field of view of a polariscope system (4) and a camera system (7). The model (2) is mounted on an adjustable stand (5). The blood vessel simulating model (2) is connected to the pump system by outlet control and access valves (10). The blood vessel simulating model (2) is connected to the pump system (3) by a clip (9). A pressure sensor (8) is provided to monitor pressure levels within the model (2). The pump system (3), pressure sensor (8), polariscope (4) and camera (7) are controlled by controllers (39, 11, 13). The adjustable stand (5) is movable to facilitate rotation, change of orientation, change of level of one end of the model with respect to the other end, and bending of the blood vessel simulating model (2). The pump system (3) circulates a liquid to the model (2) to simulate blood flow in the model.

Abstract: This invention involves pulling weights attached to the floor side of a cable. The cable circles around two pulleys with a handle at the other end to pull down the weight. The arm rests on a cushioned table top and the arm and hand pull the handle from a vertical position to a horizontal position to increase muscle tone and strength. The pull movement of the hand, wrist, elbow, tricep, bicep, shoulder, neck and back are directly related to the design of the machine to improve strength and muscle for general good health, muscle building, arm wrestling and body building. A head band attachment also allows the user to increase muscle tone in the neck, face, and back by lifting the weights in the same fashion from the far end of the table. The weights are adjustable from 10 to 150 pounds and the end result is that as your muscle tone improves, you can add more weight until the desired lift is achieved and your body strength has improved.
