Abstract: An adjustable bed allowing the knee portion to automatically rise upon the elevating of the head portion. Alternately, when desired, the knee may remain flat while the head of the bed elevates. The mechanism elevating the knee connects to the structure which effecuates the raising of the head. This mechanism occupies one position when the knee accompanies the head portion in rising and a second position when the knee remains flat. Conveniently, this mechanism consists of a cam connected to the member elevating the head portion. The cam occupies a position where it contacts a cam follower on the knee portion of the bed when the knee rises and a second position where it does not contact the cam follower for the instance where the knee remains flat. These two positions of the cam may have rotational or translational separation from each other.
Abstract: A brace for rigidly locking a casket cap in its open position to positively preclude movement of the cap about its pivotal connection with the casket body in either direction. The brace includes an elongated member pivotally mounted in a support bracket carried by the casket body and transversely displaced from the hinge for the casket cap. This elongated member then extends generally upward through an elongated slot in the casket cap which telescopes outwardly over the member as the cap is pivoted from the closed position to the open position. When the cap reaches the open position, cooperating locking means on the cap and the end of the elongated member engage to lock the cap in the open position. The locking means precludes further pivotal movement of the cap in either direction until the locking means is released. Resilient biasing means maintain the locking engagement and facilitate its release.

Abstract: In order to detect flaws in a material having a cavity, such as a turbine rotor with a central bore, a test apparatus utilizing ultrasonic signals or waves in longitudinal, shear and surface modes, or various combinations thereof, is provided. A source of ultrasonic waves is appropriately mounted for both circumferential and axial sweeps of at least a portion of the bore. Appropriate indexing arrangements are provided to accurately determine the axial and circumferential positions of the source, and hence of any detected flaws.
Abstract: A flaw detecting apparatus is insertable into the bore of a rotor being tested. A chamber is formed by a structure mounted on the rotor in a cantilever fashion. The chamber provides an area in which the test unit may be checked and worked on. Calibration blocks are located in the chamber to calibrate the amplitude and distance signals for both axial and rotational modes of ultrasonic propagation. A motor mount at the outward end is pivoted to provide ready access to the chamber.
Abstract: A portable refrigerating unit has a condenser coil which may be inserted directly into the drying chamber of a freeze drying apparatus. A flexible tube is utilized to convey refrigerant to and from the condenser coil. The flexible tube and the condenser coil are connected through a closure member, which provides a vacuum tight seal for the drying chamber of the freeze drying apparatus. The closure member may be removed from the condenser coil, so that various closure sizes may be utilized and so that the condenser coil may be utilized as an immersible refrigerating device.
Abstract: This specification discloses a coupling between two rotational shafts for transmitting torque. It includes a positive, inelastic, interconnection between the shafts for torque transmission and a resilient element to control, measure or respond to the magnitude of torque transmitted. In another context, the disclosure includes a rotational power shaft having a torque measuring, sensing and responsive unit which provides a direct visual and physical indication of the torque transmitted through the shaft while additionally providing actuating means for controlling associated systems which, in some way, are related to the quantity of transmitted torque.
