Patent number: 5207548Abstract: An apparatus (2) for transferring wafers between carriers of different densities having a loading station and unloading station; a lift for raising the wafers to be transferred into a wafer handler secured to a support. The wafer handler has two substantially cylindrical arms, cantilevered from the support with each arm provided with slotted rollers for holding and guiding wafers inserted therein. The arms are rotatable in four steps of 90 degrees each to cause the rollers to each take four different positions. A first position is for placing a first set of wafers in selected slots in the rollers, a second for holding the first set of wafers and passing a second set of wafers into a different set of slots interdigitated with the first set of wafers, a third position for holding the first and the second sets of wafers, and a fourth for transferring both sets of wafers into a new carrier. The apparatus can vary the sequence of loading and unloading and is suitable for use in automatic wafer production lines.Type: GrantFiled: November 12, 1991Date of Patent: May 4, 1993Assignee: International Business Machines CorporationInventor: Siegfried Suffel

Patent number: 5203665Abstract: An apparatus for removing compostable materials from plastic bags. The apparatus includes a conveyor having retaining members which engage and assist the conveyor in transporting the bags of compostable materials to a discharge bin. A cutting element cooperates with the first conveyor to open the bags allowing the compostable material to be emptied from the bags at one end of the conveyor into the bin where the compostable materials are subsequently discharged onto compost piles. The bags are then removed from the retaining members and transferred into a mechanism where they are bundled for disposal or recycle.Type: GrantFiled: October 11, 1991Date of Patent: April 20, 1993Inventor: Lars Lande

Patent number: 5193969Abstract: The present invention is a rotary, 3-stage wafer transfer machine. The transfer machine utilizes a pneumatically powered lift mechanism to raise wafers from a boat to a retaining area. If the next operation for the wafer is a single density operation (twenty-five wafers per boat), the wafers are the simply transferred to another boat for further processing. If the next operation for the wafers requires double density (fifty wafers per boat), a second set of wafers is lifted to the retaining area, where they are interspersed with the first set to create a double density set of fifth wafers. This set is then transferred to the appropriate boat (generally a quartz boat) for further processing. All components that could generate particulate contamination are sealed off from the transfer area. Extra duty materials are used for the components of the machine to provide unique reproducibility and eliminate much of the required maintenance as compared to the prior art.Type: GrantFiled: May 20, 1991Date of Patent: March 16, 1993Assignee: Fortrend Engineering CorporationInventors: John M.
