Granted: 2005-11-29
Abstract: An arrangement for removably attaching a drive shaft of a track belt to an output shaft of a transmission allows the drive shaft to be mounted and removed easily and rapidly with respect to the output shaft. A driving pulley of a V-belt transmission is mounted on the right end of a crankshaft of an engine. A gear box is disposed proximately on the right side of a driven pulley of the transmission.      An input shaft of the gear box supports the driven pulley.      An input shaft, an idle shaft, and a final shaft are disposed in the gear box. The outer periphery of the output shaft is sealed with a seal. The output shaft is formed as a hollow shaft projecting and opening to one side of the gear box. The inner surface of the hollow output shaft is splined, and one end of the drive shaft is inserted into the hollow portion of the output shaft. Further, splines formed on the outer periphery of the one end of the drive shaft are brought into engagement with the splines formed on the inner surface of the output shaft. Thus, the splined connection permits rotation of the output shaft to be transmitted to the drive shaft, while allowing the drive shaft to be easily mounted to or removed from the output shaft.

Abstract: An infrared intrusion sensing system comprises a compound lens having a plurality of lines of focus for focusing infrared radiation that enters the system onto a detector, and a window to allow infrared radiation to enter the system and then be focused onto the detector by a set of curvilinear-shaped mirrors. The detector is located near the focal point of the compound lens elements and curvilinear-shaped mirror elements. An enclosure surrounding the detector provides isolation from insect entry and constitutes an insect exclusion enclosure envelope. The enclosure envelope is a protective volume of space for the optical paths between the lens or window and the detector that prevents the entry of objects about 1 mm in diameter or larger which could interfere with the optical paths. Pigmenting, texturing, and/or contouring the insect exclusion enclosure surrounding the detector is provided for the purpose of absorbing and/or scattering superfluous radiation that is not focused on the detector, thereby minimizing false alarms and providing improved operating performance by the infrared intrusion sensing system. An alternate embodiment provides an insert for the insect exclusion enclosure which comprises the pigmenting, texturing and/or contouring, and permits easy update of an existing sensor systems.

Abstract: A bridging agent for improving the bond between incompatible component layers of laminates comprising one or more N-substituted melamine compounds. The bridging agent is comprised of an N-substituted melamine, an N-substituted melamine formaldehyde resin, a hybrid of an N-substituted resin, or mixtures of these resins. The bridging agent improves bonding between laminate layers known not to bond well together such as between a styrenated polyester top coat and a melamine impregnating resin. As a result of improving the bond between the incompatible component layers, the bridging agent improves the blister resistance and cove forming characteristics of the laminate. The bridging agent can be used to improve bonding both with and without a trans paper layer.

Abstract: A method and apparatus for measuring gas flow in a gas sampling device including a vacuum pump which generates pulsations and the gas flow is disclosed. The exhaust from the vacuum pump is passed through a tube having an internal diameter of about 1 mm to about 5 mm, and the length of about 10 mm to about 150 mm under substantially isothermal conditions. Pulsations in the gas flow are dampened in the pulsation damper located at the upstream end of the tube. The pressure is measured at the upstream end of the tube and the gas flow is derived from a predetermined relationship between the gas flow and the tub under substantially isothermal conditions and the upstream pressure in the tube, the large bore of the tube, allows dust particles to pass through the system rather than clog up small air passage ways. The method and apparatus of the invention provide a simple means for measuring air or gas sample flow by neutralising the effect of the back pressure caused by the pump strokes.
