Abstract: CORRODIBLE CONTAINER FOR AUTOMATIC ADDITION OF        CORROSION INHIBITOR TO A COOLANT SYSTEM               Abstract of the Disclosure A corrodible container (28, 32, 35, 38, 39, 42, 44, 53, 57, 58, 65, 69, 79, 86, 93) for the storage of a corrosion inhibitor (29, 37, 41, 43, 45, 71, 72, 73, 74, 81, 87, 94) to be suitably located in the coolant system of an automotive vehicle or other environment wherein the container has at least a portion thereof formed of substantially the same material as the material forming the heat exchange device in a coolant system so as to corrode when the coolant is partially or wholly replaced by a corrosive liquid such as water.  More specifically, an aluminum radiator has a tendency to corrode rapidly where corrosive water is present and the container for the corrosion inhibitor has at least a portion thereof formed of aluminum foil or aluminum sheet material with a thinner portion so that the foil or thinner portion will corrode through to release the corrosion inhibitor into the coolant to minimize corrosion of the heat exchanger and coolant system.

Abstract: ABSTRACT OF THE DISCLOSURE         An optical switch is disclosed in which a housing has an input receptacle and two output receptacles in a single wall of the housing.  Light passes through a collimating lense in the input receptacle to a first triangular prism where it is totally reflected twice back to a converging lense in one of the output receptacles.  A second triangular prism is situated adjacent the first triangular prism and, if it is desired that the input light be passed to the other output receptacle instead, the in-put light is passed to the second triangular prism where it is totally reflected twice and passed to a converging lens  in the other output receptacle.  In order to switch the input light away from the first triangular prism to the second triangular prism a parallelogram prism can be positioned to intercept the incoming light beam.  This prism serves to reflect the beam 90° twice to a displaced position in which it impinges on the second triangular prism.  The parallelogram prism is secured to a holder which is slidable laterally under the influence of two electro-magnets and, in this way, the parallelogram prism can be moved, as desired, into or out of the path of the incoming light beam.

Abstract: "CYLINDRICAL BALE TRANSPORTING AND UNROLLING DEVICE"          ABSTRACT OF THE DISCLOSURE          A frame is supported upon skids and includes a pair of opposed hubs which can be raised and lowered with-in the frame by hydraulic piston and cylinder assemblies. The sides of the frame and the hubs can be moved together or spread apart in order to grip and engage the ends of a cylindrical bale.  The bale may be elevated in the frame or can be lowered so that the bale engages with the ground so that when the frame is towed by a tractor or the like, the bale unrolls therebehind.  The weight of the bale, assisted if necessary by the downward thrust of the piston and cylin-der assemblies, supplies sufficient friction with the ground to unroll the bale which rotates with the hubs.

Abstract: 532.008                     AN EXPANDABLE ANNULAR LOCKING DEVICE FOR A SHAFT     ABSTRACT     The expandable annular locking device is particularly applicable for use on mill roll necks, shafts and the like. The annular locking device is adapted to be disposed in an annular groove of a mill roll neck or shaft for retaining one or more sleeve-like members, anti-friction bearings, seals, spacers or the like together as a unit against a fixed abutment of the shaft for maintaining the member or plurality of members in proper working or spaced relationship on the shaft. The annular locking device comprises a pair of arucate members, each having a pair of flat surfaces. Each arcuate member portends an arc less than 180° and their one ends are pivotally interconnected by an arcuate link whose opposite ends are nested within opposed slots of said members and pivoted thereto. When the arcuate members and links are disposed about a shaft within an annular recess and a preselected spacer sleeve is snugly interposed between the annular locking device and the sleeve-like elements, bearings or the like, and the locking devices are tightly secured to the shaft, the sleeve-like elements are retained against the abutment so as to locate and maintain the various elements on the shaft in the required working relationship.

Abstract: ANTI-KICKBACK POWER TOOL CONTROL                 ABSTRACT OF THE DISCLOSURE     An impending kickback condition in the operation of a power tool or machine tool system is sensed and used to con-trol or eliminate the kickback.  The ability to sense an impending kickback condition can be used in all categories of power driven tools.  The change in force applied to the power driven tool or other implement is monitored by measur-ing the rate of change of speed of the tool or implement, and if the speed is decreasing, the rate of change of speed is compared with a threshold value which may be either preset or variable.  If this threshold value is exceeded, an output control signal is generated which inhibits the coupling of power to the tool or other implement and/or applies a brake to stop the tool or implement.  In order for power to once again be coupled from the motive power source to the shaft, the start switch must be opened and then reclosed or some other signal provided by the operator or another predeter-mined condition must be met.

Abstract: Abstract of Disclosure An improved method and apparatus are provided for producing monocellular layers of cell-containing biological fluid, such as blood, by spinning a sample slide bearing a sample to be analyzed. In the practice of the improved method and use of the improved apparatus, the slide is positioned with the sample-bearing surface thereof facing downwardly so that the force of gravity aids, rather than hinders, monocellular layer formation.  Such layer formation is further facilitated by spinning of the slide in a holder pro-vided with integral wall means shielding the sample from the buffeting effect of circumambient air to thereby avoid premature drying of the sample, minimize cell distortion and prevent aerosol formation.
