Abstract:
A scarifier is provided with a floating axle 16 which allows the head 22 of the unit to follow the contour of the to-be-ground surface. The floating axle 16 will allow the two large outboard wheels 46 to guide the unit, but still maintain pressure on the smaller guide wheels 50. The floating axle 16 can also be locked to compensate for extremely uneven conditions.
Abstract:
A mold plate to parking location interface includes: a mold plate for holding solder; a fill head with an o-ring for dispensing solder bumps on the mold plate; a parking location for locating the fill head; and a platform between the mold plate and the parking location for relatively moving the fill head from the first location to the second location such that the o-ring decompresses as it passes over the platform.
Abstract:
A check valve comprises a housing, a fluid passage, a seat, a valve member and a stop. The fluid passage extends through the housing. The seat is disposed in the fluid passage. The valve member is positioned in the passage to engage the seat. The stop extends through the housing to engage the valve member. The stop is accessible from outside the housing to adjust a distance the valve member can travel from the seat. In one embodiment, the stop includes a variable stop feature, such as an offset pin or a cam. In another embodiment, the stop includes a pump control valve. In yet another embodiment, the housing includes markings to indicate a position of the stop. The valve member comprises a ball or a poppet in different embodiments.
Abstract:
The invention provides a method of attaching a propulsion unit 12 to a scarifier 10. The device 22 verifies via a switch 24 closure that the coupler 14 and ball 16 are attached. The switch 24 is located in the tube 26 to which the ball 16 mounts. When the coupler 14 is placed on the ball 16 a spring loaded plate 28 is depressed. This plate 28 travels down with the coupler and activates the switch 24. The scarifier 10 can be configured to prevent operation unless the propulsion unit 12 is attached via the hitch. The object of this interlock is to encourage operators to use the propulsion unit in order to minimize vibration to the operator.
Abstract:
The invention, generally (10), has an injection molded box (12), in which is mounted a small air compressor (14). The modular assembly (16) can be installed in place of the intake filters (18) on an HVLP spray system (20), with the filter componentry (18) being relocated to the air intake side (22) of the compressor package (16).
