Abstract: A reductive stripping flow sheet for recovery of uranium from wet-process phosphoric acid is described. Uranium is stripped from a uranium-loaded organic phase by a redox reaction converting the uranyl to uranous ion. The uranous ion is reoxidized to the uranyl oxidation state to form an aqueous feed solution highly concentrated in uranium. Processing of this feed through a second solvent extraction cycle requires far less stripping reagent as compared to a flow sheet which does not include the reductive stripping reaction.

Abstract: Independently operable head and foot adjusting mechanisms are provided in an adjustable motorized hospital bed in order to facilitate independent height adjustment of the head and foot ends of the bed's movable frame, on which is mounted a mattress supporting structure. Logic circuitry controls the actuation of the adjusting mechanisms to manipulate the movable frame to any level or tilted position desired. When the frame is to be lowered to its lowermost level, a latching system may be latched in a down operating mode, merely by momentarily actuating a switch, to cause the head and foot adjusting mechanisms to lower each end of the movable frame directly to its lowermost limit regardless of the frame's position, and even though the frame may be tilted, at the time the switch is actuated. With such direct and immediate access to the lowermost level position, considerable time can be saved by the nurse or attendant.

Abstract: Different hospital bed functions or adjustments (such as high-low, back and knee adjustments) may be made by employing a single reversible motor to drive selected ones of a series of adjusting mechanisms. The adjusting mechanisms may be clutched, individually or simultaneously, to the motor drive in a transmission and the motor may be run in a selected direction in order to position the hospital bed as desired. Momentarily reversing the direction of motor rotation ensures that all of the clutches in the transmission will be disengaged except those that have been actuated. The motor is momentarily reversed upon the initial operation of any function or functions, and is again momentarily reversed upon the reactivation of any function while other functions continue to operate. With this arrangement, if any deactuated clutch has locked or latched into an engaged position, it will be quickly released or unlocked so only the desired bed functions will operate.

Abstract: A disposable or reusable "crawl resistant" flexible mattress formed of panels sealed together to define alternately inflatable passages between the panels for sequentially supporting structure for a long term bed patient to reduce decubitus ulcers, bed sores, etc. The mattress has vent holes in its top for ventilating the patient with inflation gas and a crawl resistant layer bonded to a bottom of the mattress to prevent the mattress from "crawling" relative to the bed and patient during use. In one form of the mattress, crawling is reduced by a separation between the inflation passages so individual sections of the mattress can more readily conform to a patient's body contour.

Abstract: A Schottky gate FET is fabricated by forming on a semiconductor substrate first and second stacks facing each other. Each stack is constructed by an ohmic electrode and a spacer film. On the substrate having stacks formed thereon an insulation layer is formed and is anisotropically etched in the direction of its thickness until the planar surface portions are exposed. As a result, portions of the insulation layer remain on opposing side walls of the stacks. After removing the spacer films to define stepped portions between each remaining portion and each electrode, a layer of a metallic material capable of forming a Schottky barrier with the substrate is formed. The remaining portions are removed to pattern the metallic material layer, thereby forming a Shottky gate electrode.

The field oxide is formed to a thickness of less than 1 micron and typically to a thickness of approximately 0.

Abstract: A manually operated hair cutting device having a movable spring wire extending through the device. The wire has a base end for engaging one's head to regulate the length at which the hair is cut. The other end of the wire is connected to an activator which is adapted to be moved to forward and rear positions.

A movable stop normally prevents the handles from being moved together to prevent hair cutting action. An adjustable engager on the activator engages the stop and moves it out of the way as the activator moved forward to allow the handles to be moved together for hair cutting purposes.
