Abstract: A loudspeaker is constructed by circumferentially bonding a magnetic assembly in coaxial alignment rearward within a frame and installing an acoustic radiator assembly at a forward end of the frame, the acoustic radiator assembly having a cylindrical member about which a voice coil is wound, the cylindrical member extending rearward into an annular flux gap in the magnetic assembly such that the voice coil is disposed in proper alignment within the annular flux gap by virtue of the cylindrical member bearing against a mating surface of the magnetic assembly, thereby bringing the acoustic radiator assembly into substantially coaxial alignment with respect to the frame to facilitate suspension thereof at the forward end of the frame.

Abstract: The invention provides a process for reproducing pictorial works, in particular paintings, on a canvas, wood or the like support, by taking a photograph or a flat copy of the original painting, a process wherein said support is prepared by making relief portions therein which correspond to the relief portions of the original painting to be reproduced, and said photograph or flat copy are applied on to said relief support thus prepared.

Abstract: A stabilized hoist rig for lowering, lifting, and supporting a pipe string from a vessel or floating platform in a deep ocean is disclosed. A resilient bearing member is disposed in load supporting relation intermediate the vessel and the hoist rig. A powered system is provided for angularly displacing the hoist rig with respect to the vessel to maintain vertical alignment of the hoist rig with respect to the pipe string as the vessel rolls and pitches during pipe stabbing and removal operations. In a preferred embodiment, the pipe string is supported by a slip bowl and a second resilient bearing member disposed intermediate the slip bowl and the hoist rig, and a system is provided for locking the hoist rig in a fixed position with respect to the vessel for permitting the vessel and hoist rig to roll and pitch with respect to the slip bowl in response to movements of the ocean in a passive support operating mode.

Abstract: A belt is disclosed capable of transmitting power from a moving member to a pulley which has grooves spaced about the periphery. The belt has teeth spaced along it for engaging the pulley grooves to turn the pulley. Some of the teeth of the belt contain connectors which are engaged by the moving member, thus moving the belt.

Abstract: A soil working implement for use in forming a raised soil bed is disclosed. The implement includes a carriage assembly and a plowing tool mounted for rotation on the carriage assembly. The plowing tool includes a cylindrical rim and an array of soil digging teeth rigidly secured to the rim and projecting radially with respect thereto for moving soil laterally relative to the line of travel of the implement. Each tooth is characterized by an inclined face slanting away from the direction of rotation of the rim and converging to form a cutting edge which is canted at an oblique angle with respect to the line of travel.

Abstract: A chain saw having an improved safety brake actuating mechanism is disclosed. The actuating mechanism includes a safety lever pivotally mounted on the chain saw housing for movement from an operating position to a braking position in which a brake band is brought into frictional engagement with motive means which drives a cutting chain. A latching member is pivotally mounted on the safety lever for releasable latching engagement with the housing. A spring member engaged intermediate the housing and the latching member exerts a yieldable force on the safety lever which constantly biases the safety lever for movement from the operating position to the braking position while also exerting a yielding latching force on the latching member.

Abstract: An exercising device is disclosed. The exercising device comprises an elongated body support member that will accommodate a person using the device in a prone, or sitting position. Rigid elongated end members extend along and are affixed to the end edges of the body supporting member. Rigid elongated stabilizer members are attached to the elongated end members with a flexible attachment device. The apparatus is suspended from a fixed anchor device, such as a wall, ceiling, or a stable frame, by flexible suspension device that are strung between the stabilizers and the anchor points. Elastic device are disposed in at least one of the suspension device whereby the suspension device can be elongated when a force is applied to the suspension device. The elastic device disposed in the suspension device thus allows the user to cause the body supporting member to move upwardly, downwardly and/or horizontally in response to certain forces that are applied to the apparatus.

The resilient leaf portion is characterized by a spring constant which permits the leaf, when forced into engagement with the abutment, to deflect and rotate into a latched position thereon in response to a first applied force which is less than a predetermined threshold level, and which permits the leaf to deflect and pass over the abutment in response to an applied force which is equal to or greater than the predetermined threshold level.

Abstract: Apparatus and method of filling voids in a ground stratum in the vicinity of a well bore are enclosed. The apparatus is a self-contained device and, for example, it can be placed in the well bore in the vicinity of the voids to be plugged by dropping the apparatus down a drill string. Once in place it will automatically respond to the well pressure to provide the required plugging. To accomplish this the apparatus includes precursors of polymers such as precursors of polyurethanes, epoxy type polymers, polyesters or other polymers which are released from the apparatus and flow into the voids.
