  • Patent number: 6881327
    Abstract: A filter cartridge end-of-life mechanism and a filter cartridge assembly for a water treatment device. The end-of-life mechanism comprises a float which is moved along an escapement path each time the device is filled. A counting mechanism connected to the float provides a continuous visual indication of the amount of useful life remaining in the filter cartridge. The cartridge assembly includes a tray detachably connected to a filter cartridge. The tray is positioned beneath the outlet end of the cartridge to remove water treatment particles from the treated water.

  • Patent number: 6368137
    Abstract: A chip carrying socket includes a base and at least one and preferably two cam shafts journaled or supported within the base in a spaced relationship for rotational movement relative to the base. A plate is supported upon the base and extends between the cam shafts. The plate has a plurality of openings formed therein which receive the leads of an IC. In a BGA type IC, these leads are semi-spherical balls which depend from the lower face of the IC. Conductors or pins adapted for connection to testing or operative circuitry are carried by the base and extend into proximity with the leads of the IC as it is supported upon the plate. Each cam shaft engages the plate so as to shift the plate relative to the base causing the conductors carried by the base to forcibly engage the leads of the IC when in one shifted position and causing the conductors to be released from such forcible engagement with the leads of the IC when in a second shifted position.

  • Patent number: 5605139
    Abstract: A target trap having a ratchet and pawl mechanism for partial recocking after a target has been thrown is disclosed. The trap includes a frame having a stationary ratchet wheel with contiguous ratchet teeth along a portion of the perimeter of the ratchet wheel. A biased pawl is mounted onto a throwing arm assembly for interacting with the ratchet wheel to hold the throwing arm assembly in a partially cocked position after the trap has been fired. The ratchet and pawl mechanism is arranged such that the throwing arm assembly can always be rotated in one direction so that an operator can move the throwing arm assembly into a cocked position. From the cocked position the throwing arm can move freely in the opposite direction to throw the target.
