Abstract: Embodiments of the disclosure generally provide polishing pads having a composite pad body and methods for forming the polishing pads. In one embodiment, the composite pad body includes one or more first features formed from a first material or a first composition of materials, and one or more second features formed from a second material or a second composition of materials, wherein the one or more first features and the one or more second features are formed by depositing a plurality of layers comprising the first material or first composition of materials and second material or second composition of materials.

Abstract: A garment tag reading system which includes a Kimball tag reader and a data processing unit is described for reading and decoding information encoded on a garment tag. An interface unit is used to permit direct communication between the tag reader, which has a memory for storing the coded information read from the garment tag, and the data processing unit. The interface unit includes a column driver having a plurality of low voltage amplifiers which provide amplified output voltages in response to voltage-level increases caused by the programmed operation of the data processing unit. The output voltages are serially applied to the tag reader memory for interrogating the memory to retrieve the coded information. The information from the tag reader memory is received by a data input/output circuit in the interface unit in the form of decimal coded output voltages and is subsequently entered into the data processing unit for decoding into a readable format.

Abstract: The present invention provides an automatic streaking device for bacterial specimens, which device produces a repetitive, overlapped plurality of figure eight patterns. An electrically conductive loop is displaced in a direction perpendicular to the major axis of the figure eight pattern. Means are provided for non-linearly advancing the loop in a direction perpendicular to the major axis of the figure eight pattern so as to vary the resulting pattern in a predetermined manner. Means are also provided for automatically sterilizing the loop when the series of figure eight movements are terminated. A first motor drives a pair of crank arms having different lengths in order to determine the amplitudes of the figure eight patterns in two mutually perpendicular directions. A second, variable speed, reversible motor is coupled to and drives a carriage that supports the first motor and the crank arms so as to vary the center-to-center spacing between adjacent figure eight patterns.
