Abstract: Radiological apparatus, such as bone densitometry measurement systems that utilize a penetrating radiation source, such as an x-ray source is provided. Theapparatus includes a patient table with a length extending along a Y-axis and a width extending along an X-axis and a C-arm supporting, for example, an x-ray source at one side of the table and an x-ray detector at an opposite side of the table such that the source and detector are aligned along a source-detector axis. The source is selectively energized to emit a fan beam of x-rays which conform to a beam planewhich is transverse to the Y-axis and contains the source-detector axis. Either, or both, the C-arm or the table are selectively movable relative to the other along the X-axis, along the Y-axis, and along a Z-axis which is transverse to both the X-axis and the Y-axis, so that selected regions of a patient on the table can be selectively scanned with the fan beam of X-rays. In addition, the C-arm is selectively rotatable around a rotational axis extending along the Y-axis to selectively change the angle of the fan beam relative to a patient on the table. The apparatus of the present invention provides various functions that complement and enhance the scanning function and resulting images derived from detected x-rays. For example, the apparatus has a multi-position attenuator mechanism for placement of different attenuating materials in the radiation beam. The apparatus also includes a detector response flattener coupled to and responsive to the output of detector elements in the x-ray detector. A dark current system interleaves the detector outputs with darkcurrent responses of the detector elements and accounts for dark current characteristics of the elements. The apparatus includes an optical crosshair device that projects a visible crosshair coaxial with the source-detector axis, and patient positioning aides operative in conjunction with the patient table which facilitate positioning of x-rays and the patient for certain bone density measurements. Theapparatus of the present invention may also be constructed as a portable unit suitable for transportation between rooms of a medical facility through generally standard doorways. The portable unit has a base portion capable of rolling ambulation by at least one human operator during transportation and selective stabilization on a floor for patient scanning, and a patient table.

Abstract: A pear processing method and apparatus  is provided which includes several mechanisms  for properly orienting the pear prior to coring, peeling and seed celling of the pear.  Each pear is tumbled between a pair of orienting rolls to a position wherein the stem of the pear is  oriented  downwardly. Whiskers  on one of the rolls speed up this orienting of the pear. A friction clutch on the other roll helps maintain the pear in its proper position, once the proper alignment has been attained.  The pear is dropped downwardly into a transfer cup having four resilient  fingers which tend to orient the pear.  The pear is then pushed out of the   transfer cup downwardly into a feed cup having  a   concave  receptacle for centering  the stem of the pear and three upwardly  extending arms which grasp and center the blossom end of the pear. The pear is then  transferred to a station wherein the pear is cored and thereafter peeled and seed celled  simultaneously. The stem and blossom are also trimmed.  The pear is  thereafter passed into a slice cup having a design which more effectively separates the waste from the processed pear.
