Abstract: A pin wheel roller assembly for a bacon slicer. The roller assembly is formed with a number of individual spacer segments and an end cap. The pin wheel assembly is formed with a pin wheel sandwiched between adjacent cylindrical segments and the end cap.

Abstract: An improved meat deboning apparatus of the horizontally-arranged type, which is linear in a horizontal plane and fully supported by an integral base member throughout its length. Among the improvements made is the elimination of the prior art one-piece feed can and replacement with a split feed can with a replaceable insert. The split feed can of the present invention has a bottom half and a removeable top half. A replaceable insert is contained within. The insert is replaced by removing the top half of the feed can, removing the old insert and replacing it with a new insert. Because the feed can top half is removeable, a one-piece auger may also be used rather than the multiple-sectioned augers required by the pressure housings of the prior art. The thrust bearing and bearinged pillow blocks of the prior art are replaced with spherical roller bearing pillow blocks, thereby eliminating the need for a thrust bearing and its associated housing.

Abstract: An adjustable surgical arm rest and instrument platform for supporting the arms and hands of a surgeon during a micro-surgical procedure, in which a supporting platform is provided with vertical and angular adjustment mechanisms which permit rapid adjustment of the platform before, during and after the operation. Two or more platforms may be used, and each platform can be adjusted independently of the other platforms. The angular adjustment of a platform can be performed independently of the vertical adjustment of the platform. Each mechanism is provided with a two part securing feature so that the platforms will not move accidentally. An oxygen/air tube may be attached during local procedures to supply oxygen.

Abstract: An arm and hand rest device for performing microsurgery, such as an eye operation, on a patient lying on an operating table, the device having a board placed on the operating table beneath the upper body portion of the patient so that the weight of the patient will hold the device firmly in place. Two tables are disposed at the head end of the board and each includes a platform on which the hands and arms are rested while the surgeon uses a scalpel or other instrument in performing the operation. The tables are spaced from one another to define the area in which the patient's head is placed for the operation, and the platforms are adjustable vertically and have projections at the top end extending toward one another.
