Abstract: An electromechanical compression release valve for compressors, engines with rotary or reciprocating mechanisms and external combustion engines, such as, a Stirling cycle engine, reduces the engine starting power by reducing the compression pressure in the cylinder head space area. The valve reduces the compression pressure by passing the working fluid from the cylinder head space to another compartment. The valve comprises a housing, a valve member, a valve-driving member, a valve position sensor, and a ratchet pawl. In the open position, and while starting the engine, the inlet of the rotatable valve member is aligned with the opening in a chamber connected to the engine work space, thus, the working fluid passes through the valve member into the crankcase. After the engine starts, the valve position sensor directs the valve-driving member to rotate the valve member to the closed position. When closed, the engine working fluid can now achieve the operating compression pressures.

Abstract: An electrically isolated, combined power and signal coupler, for a patient connected device, is disclosed. A docking station and a portable device, capable of docking with the docking station each include a power coupler and an electrically isolated data transducer. The respective power couplers include a magnetically permeable element including a central pole and a peripheral pole and a printed circuit board with an opening through which the central pole protrudes. The printed circuit board includes windings surrounding the central pole opening: a primary winding in the docking station and a secondary winding in the portable device. When the portable device is docked with the docking station, the magnetically permeable element in the portable device and the magnetically permeable element in the docking station are arranged to form a magnetic circuit, and the data transducer in the portable device and the data transducer in the docking station are arranged to exchange data.

Abstract: A medical workstation chassis including a first compartment and a second compartment. The first compartment is formed as a monolithic aluminum casting which includes pedestals which mate to heat generating electronic components such as integrated circuits mounted within the first compartment. A plastic thermal barrier is sandwiched between the first compartment and the second compartment to attenuate heat transfer from the chassis to the components, such as a disk drive and battery, housed within the second compartment. A series of heat sink fins are formed along the lateral perimeter of the aluminum casting and are interconnected to the pedestals by a series of large cross section ribs which are also formed as part of the aluminum casting.

Abstract: An automatic blood pressure monitor has a dual-speed control circuit which is used to control the speed of a DC motor that powers the inflation cuff. The control circuit limits the motor current, permitting operation from a limited power source (such as a battery). The control circuit also includes structure for electrically braking the motor; the motor is braked after a time delay which commences after motor power is cut off.

Abstract: A hammer mill for treating scrap metal including a rotary hammer means for delivering impact blows to scrap metal is shown. Discharge grates are provided for disposing of the scrap metal through discharge outlets for the hammer mill. The rotor is a disc type with rotating hammers located on pins extending through the discs. A plurality of caps are circumferentially located around each disc and attached thereto for protecting the disc against excessive wear. A dual feed roller feeds the scrap metal to the hammer mill to be shredded.
