A exercise device includes: a u-shaped frame; first and second arms pivotally coupled to ends of the frame; a first pair of bands that resist pivotal movement between the u-shaped frame and each of the first and second arms; and an arm bar. The arm bar is releasably coupled proximate to the free end of each of the first and second arms. As configured the device is usable for a first set of exercises. A first end of each of a second pair of resistance bands is respectively secured in proximity to first and second ends of the arm bar. The second ends of the second pair of resistance bands have loops fixedly secured thereto. When the arm bar is not releasably secured to the first and second arms, it is usable in combination with those bands and loops for a second set of exercises, providing a full body workout.

During scribing of a ceramic plate with a laser beam, ceramic particles rise from the workpiece in a direction of motion that is generally the same as that of the workpiece. The lens on a laser scriber is protected from abrasive contact with such particulates in the atmosphere by slipping the base of a housing over the circumference of the lens mount and forming a generally airtight seal between them. The housing is shaped like a frustum of a right circular cone, with the apex end thereof truncated and essentially rolled over to form an orifice through which the lens axis and laser beam pass. A plurality of streams of pressurized air are introduced into the housing near the midpoint of the frustum and the lens surface. The air streams are introduced tangent to the inner surface of the housing and angled downward for producing a vortex of air that is exhausted to the atmosphere through the orifice at a velocity and vorticity that inhibits particulates outside of the cover entering the orifice. A suction hose is located in front of the housing for removing particulates from this area. In an alternate embodiment, a directional air lock door is established in front of the lens, with the airstream that establishes the door being directed into a suction hose. The direction of this airstream is preferably maintained the same as the direction that the workpiece moves.

Rectangularly shaped snapstrates are separated into substrates along kerfs that are parallel to edges thereof by belt and roller flexure forces produced by two belts that are caused to be contiguous over the suspended length of the upper belt by a pressure roller forcing the two belts together at an intermediate point between roller supports for the belts. This produces oppositely facing curvatures in the belts at spaced apart transverse lines thereon which flex snapstrates in opposite directions with a flexure force which is sufficient to separate snapstrates on the lower belt with kerfs facing in the right direction and which is not sufficient to separate snapstrates there with kerfs facing in the wrong direction. In an alternate embodiment, the peripheries of rollers are tapered in vertical sections for separating snapstrates along kerfs oriented at right angles. In a further embodiment, only a single belt with a pressure roller pressing down on it is employed to separate snapstrates.

This invention is a splash and spray control shield for the wheels of large vehicles, such as trucks and trailers, and is designed to control the wet weather splash and spray generated by the centrifugal force of the forward rotation of the wheels of such a vehicle traveling over wet road surfaces. This shield consists of a unit with sidewalls that covers the uppermost forward part, over the top of and the uppermost rearward part of the wheel or dual wheels, or wheels of adjacent axles. The uppermost forward section of this shield consists of an air collector known as a 'scoop'--which is aerodynamically designed to collect and direct the flow of air caused by the forward movement of the vehicle, across the top of, backwardly and downward, behind the wheel or wheels or most rearward wheels of a set of adjacent axles, directly to the road surface. This flow of air transports wet weather road surface material such as water, snow, salt, mud, pebbles, and the like, which usually emanates as splash and spray, on a downward direction and returns it to the road surfaces so as not to discharge it into adjacent traffic lanes. The front and rear of the wheel opening on each side of the shield is arcuately shaped in approximate conformity with the arcuacy of the wheel periphery and this wheel opening has a resilient extension which will increase its effectiveness and will provide ease in tire and wheel maintenance. A resilient shield extension is fastened to the lowermost rear section of the shield to aid in returning the wet weather mixture to the road surface.

A substrate grader accepts or rejects a substrate depending upon the degree of warp and then sorts the accepted substrates according to a dimension thereof. The grader comprises a first plate which is U-shaped and inclined at an acute angle with respect to the horizontal, the two arms of the first plate extending above the base thereof. A first elongated member (or lower guide) that is attached to the front of the base has a straight side which is adjacent to and spaced a short distance away from the opening in the first plate. A second elongated member, that is attached to the back of the free ends of the arms, supports a second plate (or upper guide) thereon which extends between the arms, which has a top surface in a plane containing the top surfaces of the arms and base, and which has a stepped edge in the opening. Successive stepped surfaces of this edge are parallel to and spaced progressively farther from the straight surface of the first member such that rectangular substrates contacting these spaced apart surfaces may fall through an opening therebetween to be sorted according to ranges of the length thereof. A pair of flat plates that are supported a prescribed distance above one arm receive substrates therebetween for measuring warp in the substrates. The first plate is mounted on a vibrator which causes substrates to move across this plate.

Printed circuit boards are moved in a conveyor with the underside of flat boards spaced a prescribed distance above the top surface of a rotating cutting disk. In order to protect the circuit patterns on the underside of the board and the board itself, a V-shaped wheel is loosely rotatably supported on a shaft with the wheel being in front of and orthogonal to the cutting disk. The height of the wheel is adjusted such that the uppermost point on the circumference thereof is in the line of travel of the boards. Movement of a board that is bowed downward in the direction of the disk causes the wheel to roll on the underside of the board and to raise the board above the top of the cutting disk. In this manner, the underside of warped circuit boards is maintained at least a prescribed distance above the top surface of the cutting disk as the board moves over the leading - cutting edge of the latter and component leads are trimmed thereby. Weak compression springs on either side of the wheel allow it to move sideways when it contacts a component lead. The spacing between the wheel and the front edge of the cutting disk is also adjustable.
