Abstract: Disclosed is a device for securing and lubricating a bushing. The device comprises: a first member having a first body portion, a first engaging portion extending outwardly from the first body portion, and at least one channel drilled through a lateral outer surface of the first engaging portion and extending along a complete length of the body portion; and a second member having a second body portion and a second engaging portion disposed internally and along a longitudinal axis of the second body portion. The first engaging portion mounts a bushing covering at least a portion of an opening of the channel on the lateral outer surface and engages with the second engaging portion, thereby sandwiching the bushing between the first member and the second member. Pressurizing a lubricant through the channel transmits the lubricant to an inner surface of the bushing through the opening of the channel on the first engaging portion.

Abstract: An arrowhead assembly includes a blade tube that may rotate in flight at a rate during flight that is independent from the arrow shaft rotation. The assembly, upon and after impact with the target, continues rotational motion of the blade tube to penetrate a substantial distance into the target. Such characteristics are facilitated by the spiral-shaped, or twisting, nature of the blades as well as the rotational motion that is imparted by a spring arrangement of the assembly after compression and expansion of the spring arrangement upon impact.

The level indicating member is disposed on the elongated member. The gauge member is disposed on the elongated member, and the jack screw member is disposed adjacent to the gauge member on the elongated member. The elongated member may be placed on the body for measuring the deviation of the body to determine the amount of shimming requisite for the body. The jack screw member is capable of adjusting the elongated member on the body until the level indicating member indicates a horizontal orientation of the elongated member on the body. The gauge member is capable of measuring the deviation of the body, at the horizontal orientation of the elongated member on the body.

Abstract: Disclosed is a projectile launching apparatus capable of launching a projectile, such as a pellet, a BB, an arrow, a dart and a paintball. The projectile launching apparatus includes a motor driven linear motion converter, a cylinder, a breech assembly and a compression valve arrangement. The linear motion converter converts a rotational movement of a motor into a linear movement of a piston by a gear reduction mechanism. The linear movement of the piston within the cylinder compresses a gas with a high compression exponent. The compressed gas is further released into a barrel of the breech assembly through the compression valve arrangement. The compressed gas expands in the barrel causing a projectile to be launched from the barrel with a force of the compressed gas.

The body member is configured to be received over the second end portion of the funnel-shaped member and capable of removably attaching to an external portion of the urinary catheter. The body member comprises a torus-shaped structure and at least one elongated tubular structure. The torus-shaped structure comprises at least one channel. The at least one channel is capable of receiving the at least one elongated tubular structure for looping around the torus-shaped structure for immobilizing the urinary catheter.

Abstract: A fastener driving apparatus includes a power source, a control circuit, a motor, a first cylinder, a first piston, a linear motion converter, a second cylinder, a second piston, an anvil, a valve arrangement and at least one sensor. During a compression stroke, the first piston is configured to compress gas in a first cylinder to a predetermined pressure. At the predetermined pressure, the valve arrangement assumes an open position for communicating the compressed gas to the second cylinder, thereby causing the second piston to move linearly and enabling the anvil to drive the fastener into the workpiece. During a return stroke, at a predetermined position of the first piston in the first cylinder, the valve arrangement assumes the open position for communicating a vacuum created in the first cylinder to the second cylinder and thereby causing the second piston and the anvil to retract to their initial positions.

Abstract: A portable motor driven air gun powered by a power source includes a motor that is coupled to a linear motion converter which drives a piston. The piston compresses air in a chamber against a forward air compression valve producing high-pressure air. When sufficient energy is stored within the air stream by the piston, the compression valve opens which releases the compressed air to push a projectile through a barrel. The engagement and disengagement of the linear motion converter and the connected piston to the motor can be controlled using sensors. The linear motion converter further is coupled to a bolt thru a lost motion device to facilitate positioning of the projectile for firing. The direction speed and operative modes of the gun may be controlled with an electric circuit. The power source is preferably rechargeable, allowing the air gun to be operated independent from either a wall outlet or a compressed air supply.

Abstract: A portable motor driven air gun powered by a power source includes a motor that is coupled to a pinion which drives a rack connected to a piston. The piston compresses air in a chamber producing high-pressure air. When sufficient energy is stored within the air stream by the piston, a valve opens which releases the compressed air to push a projectile through a barrel. The pinion rotates until it comes to an interrupted thread surface, at which point the rack and pinion are returned to the starting position via a spring. The piston may be coupled to a bolt thru a lost motion device to facilitate positioning of the projectile for firing. The direction speed and operative modes of the gun may be controlled with an electric circuit. The power source may be rechargeable, allowing the air gun to be operated independent from either a wall outlet or a compressed air supply.
