Abstract: A machine for washing vehicles such as large trucks and tractor-trailer combinations includes a triangular frame at each side of the path of the vehicle during the washing operation. Brushes rotatable about horizontal axes wash the front, top and rear of the vehicle. A first brush is mounted to be pushed upwardly by the front end of the vehicle as it moves through the apparatus and a second brush moves downwardly under its own weight in contact with the rear end of the vehicle. These brushes also engage the top of the vehicle. The first brush may be raised to clear exhaust stacks and the like, and the second brush is retained at an elevated position until the vehicle enters the apparatus sufficiently for it to be lowered onto the top. When the second brush reaches the lower end of its track after the vehicle departs, it is restored to the elevated position.

Abstract: A chronograph uses a Doppler radar technique to determine the muzzle velocity of a bullet discharged from small arms such as pistols and rifles. A radar unit is placed in near proximity to the firearm to track the bullet while it is still relatively close to the muzzle. The radar unit is equipped with an antenna which is insulated from the sonic disturbance created by the firearm blast by sonic damping means formed exteriorly on the antenna. Measured spacing and orientation of the antenna with respect to the firearm diminishes the sensitivity of the antenna to the electromagnetic disturbance associated with the firearm blast. Doppler signal processing means are also disclosed.

Abstract: A grinding machine having a fixed wheelhead and a biaxially movable workslide. The workslide is mounted on a cylindrical slidebar for axial sliding motion as well as pivotal motion around the bar. A dresser assembly is also mounted pivotally on the slidebar for selective dressing operations. The workslide may be moved axially into an overlapping relationship with the dresser such that the workslide is carried with the dresser over a range of pivotal displacement thereof. An hydraulic cylinder is used to pivot the dresser and a precisely positionable stop is used to control all lateral feed motions. Axial speed is programmed by a control valve. The dresser is pivotal on its base to produce a true circle wheel profile.

Abstract: A mechanism for receiving elongated articles such as dowel pins, etc., from a bulk source is disclosed which separates the pins and positions them for ejection and insertion by a ram driven driver tool. The mechanism includes a rotary feed cylinder having a plurality of pin receiving chambers extending in directions tending to converge and arranged circumferentially about the feed cylinder axis. The feed cylinder is adapted to receive pins into each chamber via an inlet from the bulk source, while upon rotation about its axis the feed cylinder repositions the pins to be horizontal in the ejection position so to be able to be advanced out of the chamber by means of the driver tool. Rotation and positioning of the feed cylinder is produced by a unique indexing arrangement operated by the driver tool ram, including a ratchet wheel drivingly connected to rotate with the feed cylinder.

Abstract: A torque measuring apparatus having a head adapted to rotate about an axis of rotation and a lever arm extending from the head and perpendicular to the axis of rotation designed to react to normal forces applied at a distance from the head. On the lever arm are a plurality of strain transducers spaced apart a certain distance as determined in accordance with predetermined mechanical properties of the lever arm. The transducers are joined electrically to form a bridge circuit, the output of which is directly proportional to the torque on the workpiece. This output is then transmitted to a display for a visual presentation of the torque.

Abstract: A knock-down storage and display stand which is easily assembled without the use of tools or fastening devices. The stand is constructed of a light-weight material such as plastic or corrugated paperboard and comprises front and rear uprights having their bottom edges wedge-fitted within a peripheral channel in a rectangular base member.
