Abstract: A drive shaft containment bracket adapted for attachment to a stationary vehicle support surface, the bracket including an elongated body having a mounting flange at one end and a drive shaft containment device at an opposite end. The elongated body has a length dimension sufficient to extend from a vehicle cross frame member supporting the transmission of the vehicle where said mounting flange is utilized to secure said bracket to the cross frame member and transmission casing, rearwardly beyond a universal joint connecting the drive shaft to the transmission to a location along the drive shaft where said containment device at least partially encloses said drive shaft.

Abstract: A seat assembly includes a seat tube in which a seat post is movably received therein which has a clamping member with a seat disposed thereto. The seat post has two plain portions defined diametrically opposite in an outer periphery thereof and the seat tube has two wedge-shaped recesses defined diametrically opposite in an inner periphery thereof so as to receive two wedge-shaped blocks therein. The seat post extends through a nut member which is threadedly mounted to the seat tube.

Abstract: An aircraft engine is attached to the fuselage by a mounting structure that has a vibration absorbing system which includes first and second sensors to produce signals indicating vibration along two orthogonal axes. A third sensor, such as an accelerometer, is coupled to the mounting structure for sensing vibration of the engine. A tachometer circuit, connected to the third sensor, produces first and second speed signals that indicate the speeds of two rotating spools in the engine. Four vibration absorbers are attached to the engine mounting structure and controllers are provided to dynamically tune the resonant frequency of each vibration absorber in response to a unique combination of one of the two vibration signals and one of the two speed signals. Thus the vibration absorbers reduce the engine spool vibrations that are transmitted through the mounting structure along the two orthogonal axes.

Abstract: A hydraulic antivibration support comprises an annular elastomer body surrounding a central axis and interconnecting a first support member and a support plate both of which are likewise annular. The elastomer body has two concentric annular cavities closed by the support plate, and constituting a working chamber and a compensation chamber which is radially defined on the outside by a thin side wall of the elastomer body, said two chambers being filled with liquid and being interconnected by a constricted passage which is defined in part by a channel-section piece located in one of the two chambers.

Abstract: A protective container for a scuba tank. The container is made of rugged, flexible material, such as plastic or rubber. The container has an open top for placing the container over the tank, a cylindrical body for protecting the side of the tank, and a base for protecting the bottom of the tank. The upper portion of the container is tapered gently inwardly and upwardly to decrease resistance to the water. The inner surface of the container has longitudinal ribs for draining water from the top to the bottom of the container. The outer surface of the container has five longitudinal outriggers to prevent rolling of the tank when it is lying on a surface and providing the least amount of resistance to the water when the tank is in use. The container wall is extended below the base to supply protection against vertical stress when the tank is dropped. The inner surface of the base contains radial drainage channels to dispose of water inside the container. The outer surface of the base contains strengthening ribs.

Abstract: The invention is a bag stand which holds a leaf bag in an upright position and maintains the bag in an open position The bag stand has a u-shaped base which holds a support rod in a vertical position. A circular ring is attached to the top of the support rod and extends parallel with the base. A leaf bag is folded radially outward as to overlay the circular ring and are held in place by bag clips. The circular ring, support rod, and u-shaped base easily disconnect for easy storage during non use.

Abstract: An engine mounting system for an internal combustion engine includes a bracket adapted for attachment to an engine and detachable locator members which are attached to fasteners extending axially from the bracket through the frame member of a vehicle. The detachable locator members wedge the engine mounting brackets into a desired location upon the frame crossmember. Once the engine has been decked, the locator members may be removed so as to allow installation of additional fastening elements.
