  • Dual locking hydraulic actuator for structural brace
    Patent number: 9944385
    Abstract: A lockable actuator has lock segments that move into recesses inside a piston to enable the piston to move. The lock segments may also move radially outwardly from the recesses in the piston to engage a bevel edge of a cylinder housing assembly to lock the piston. Lock rams having ramps force the lock segments radially outwardly into engagement with the bevel edge of the cylinder housing assembly.

  • Methods and kits for separation and detection of proteins in biological samples
    Publication number: 20020072590
    Abstract: Methods and kits are provided for separating a mixture of proteins in a biological sample. Methods for detecting and profiling proteins in biological samples by the separation method and kits are also provided. These methods are particularly useful in assessing damage to cells such as cardiac and skeletal muscle cells and in the early clinical diagnosis of myocardial damage by detection of myofilament proteins in serum of a subject.
