International Classification:

B24B049/00

US Classification:

451 5, 451 41, 451285

Abstract:

A modular fluid-dispensing system includes a master control dispenser and/or one or more satellite dispensers that communicate bi-directionally with the master control dispenser. The master control dispenser is programmable and may dispense one or more solutions. Each satellite may dispense fluid in either a stand-alone mode or under control of another fluid-dispensing-system component, such as a master control dispenser, or a grinder/polisher. A master control dispenser may store various multi-step dispensing methods and may advance a dispensing method to a next step automatically or based on a control signal received from a grinder/polisher. A master control dispenser may perform a fluid-dispensing method that is synchronized with a corresponding grinder/polisher method performed by a grinder/polisher that is coupled to the master control dispenser.

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

B24B 19/00

US Classification:

451460

Abstract:

A slide holder for mounting to a sample holder having a pair of openings therein, for a grinder/polisher includes a plate for receiving the slide. The slide holder includes a pair of stems extending from the plate and configured and spaced for receipt in the sample holder openings. A locking element is mounted to each stem. The locking elements are mounted to pivot eccentrically relative to a center axis of each stem. The stems are inserted into the sample holder openings and the locking elements are pivoted to lock the slide holder to the sample holder and to prevent the stems from disengaging from the sample holder.

Michael F. Hart - Mundelein IL, US

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

B24B 21/18

US Classification:

451444, 433 78, 13735516, 13735523

Abstract:

A retractable water dispenser arm system for a grinder/polisher includes a flexible hose formed, in part in a loop and affixed at at least one location to a base of the grinder polisher. A spout is mounted to an end of the flexible hose. A biased tension arm engages the hose at the loop, and is moveable, along with movement of the hose, to maintain the hose in tension. The biased tension arm includes a roller over which the hose traverses. A mount on the base is configured to receive the spout and is further configured for traverse of the hose therethrough. The mount includes a mount roller operably mounted thereto for guiding the hose through the mount.

B24B 7/10

US Classification:

451 5, 451548, 451259

Abstract:

An abrasive saw having an associated cutting wheel is used for cutting objects. The saw includes a base, a cutting assembly operably mounted to the base and a controller. The cutting assembly includes a pivot shaft, a drive shaft operably mounted to the pivot shaft, a drive, and a drive wheel. A flexible drive element operably connects the drive shaft and a drive wheel. The distance between the drive wheel axis of rotation and the drive shaft axis of rotation is variable to increase or decrease a tension in the flexible drive element. A feed table is operably mounted to the base and is movable forward and rearward in a direction of rotation of the associated cutting wheel. The cutting wheel is lockable in the cutting position and the feed table, with the object secured thereto, is moved, by the controller toward the associated cutting wheel to cut the object. An enclosure encloses the cutting assembly and has stationary sides and openable front and top panels hingedly mounted to one another and to a portion of one of the side panels to open as a unitary assembly for access to the cutting assembly.

B24B 37/34
G01N 1/32

US Classification:

451398, 451364

Abstract:

An improved grinder/polisher includes a base having a bowl, a rotating drive plate and a drive plate drive that is adapted to support a platen. The grinder/polisher includes a head configured to support a specimen holder. The head has a first drive for rotational drive of the specimen holder and a second drive for moving the specimen holder toward and away from the drive plate. The head includes a load cell operably connected to the first drive and a counter operably connected to the second drive. The counter is configured to determine movement and the extent of movement of the head toward and away from the drive plate. The grinder/polisher includes a control panel mounted within a housing and including a microprocessor controlled control system having a touch panel or screen.

Appl. No.:

8/681018

Inventors:

Michael F. Hart - Mundelein IL
Scott D. Holt - Round Lake Beach IL

Assignee:

Buehler, Ltd. - Lake Bluff IL

International Classification:

B24B 4106

US Classification:

451272

Abstract:

Apparatus and method for grinding semiconductor chips and other specimens prior to microscopic examination thereof by supporting a specimen on a specimen mount, fixing the specimen mount to a lower end of a lower arm, connecting an upper end of the lower arm to a swingable arm by a horizontal pivot which permits the lower arm and specimen mount to move upwardly and downwardly relative to the swingable arm, providing a stop to limit downward movement of the specimen mount relative to the swingable arm when the lower arm reaches a zero position, moving the swingable arm downwardly to lower the specimen to engage an underlying rotatable grinding platen to define a zero position, and continuing to move the swingable arm downwardly beyond the zero position by an amount corresponding to the amount of material to be removed from a lower portion of the specimen so that the stop will prevent removal of additional material.
