Abstract: A weapon, such as a crossbow or firearm, may have a main beam, a trigger mechanism mounted to the main beam and, a support rod that can be positioned into a first use position and a second stowed position. The support rod may have a first end used to support the main beam and a second end used to contact a ground surface. In one embodiment, a contact member with a hemispherical contact surface is attached to the second end of the support rod. In another embodiment, the support rod has a handgrip portion that receives a user's hand in supporting the weapon when shooting the weapon when the support rod is in the second stowed position. In still another embodiment, a mounting bracket is used to provide at least two locations for attaching the support rod to the main beam.
Abstract: There is provided a process for manufacture of optically-active, 2-(acyloxymethyl)-1,3-oxathiolanes of Formula I comprising a preparation of a racemic compound and an enzyme-catalyzed kinetic resolution of the enantiomers. The invention may further provide for the esterification and racemization of the by-product of the enzymatic reaction. In this manner, 2(R)-(benzoyloxymethyl)-1,3-oxathiolane is prepared as a useful intermediate for manufacture of the anti-HIV drug Apricitabine.
Abstract: An angled grip may allow a wrist, a palm, and a forearm of an associated user to be substantially aligned when aiming or discharging a weapon. The angled grip may be selectively attachable to the weapon and may comprise a ball joint mount for operatively connecting the angled grip to a weapon. The ball joint mount may comprise a shaft and a spherical portion. The shaft can be fixedly received in a stock of the weapon. The spherical portion can be rotatably received in a socket formed in an end of the angled grip.
Abstract: A crossbow having a crossbow grip guard that has a member that extends outwardly in a direction that is substantially perpendicular to the longitudinal axis of the crossbow barrel or stock, and wherein the member extends for a length in a direction that is substantially parallel to the longitudinal axis of the crossbow barrel or stock.
Abstract: A forced-air heater having a self-contained on-board electric-power supply that allows the forced-air heater to operate without an external electric power source; a fuel tank; a combustion chamber; a support; a housing including upper and lower housing portions; a motorized fan that during operation draws in ambient air through an air intake and forces air into the combustion chamber.
Abstract: A crossbow includes a body having a stock member and a barrel connected to the stock member. The barrel has an arrow receiving area for receiving an arrow. The crossbow also includes a bow having a pair of bow arms, a bowstring connected to the bow arms, a bowstring release mechanism used to hold and release the bowstring and, a scope mount used to hold a scope. An arrow retention spring is provided for retaining the arrow to the arrow receiving area. A vibration dampener may be positioned between the arrow retention spring and the scope mount in order to dampen the arrow retention spring vibrations made when shooting the crossbow. This greatly reduces unwanted noise.

Abstract: A common use pedal device for automotive vehicles comprises a base plate and a pedal pivotably attached to the base plate and having a push rod extending downwards from an underneath surface of the pedal. A rotating member is mounted to the base plate in such a manner that the rotating member can be depressed and rotated by the push rod of the pedal, the rotating member having a pulling arm adapted to pull a manual operating cable in response to rotation of the rotating member. A rotation detecting sensor is provided on one side of the base plate for detecting the degree of rotation of the rotating member and then notifying an electronic control unit of the degree of rotation thus detected. This pedal device can be employed in common in a manually controlled pedal type vehicle and an electronically controlled pedal type vehicle.
