Title: Fluidised bed heat exchange apparatus
Inventor: LARGE JEAN-FRANCOIS
IPC: B01J8/18
Filed: 1986-04-23
Granted: 1989-12-14
Abstract: A heat exchanger comprises two fluidization chambers separately supplied with fluidization gas. A heat transfer medium in the form of particulate material is supplied to the first chamber which is in communication with the second chamber. The second chamber has an outlet for discharging the heat transfer medium and contains a plurality of heat exchange tubes immersed in the fluidized bed therein. The particles of the heat transfer medium have average dimensions between 50 and 3,000 micrometers, and the maximum speed of the fluidizing gas in the second chamber is between 1.5 times and 10 times the minimum speed of fluidization of the particles of the heat transfer medium. Adjacent heat exchange tubes are arranged to be spaced by a horizontal distance which is between 1.4 times and 2.1 times the external diameter of these tubes. Additionally, the tubes have a vertical spacing between 1.4 and 2.1 times the external diameter of these tubes. By these means efficient heat exchange between the particulate material and a fluid flowed through the tubes is achieved.

Title: Dc/dc converter switching at zero voltage
IPC: H02M3/335
Filed: 1990-10-18
Granted: 1993-04-29
Abstract: A two switch, DC/DC converter provides sufficient inductive energy storage at the termination of the "on" period of each switch to alter the charge on the intrinsic and stray capacitance of the combination of switches producing zero voltage across the alternate switch prior to its turn on. A short dead-band between the turn on pulses provided by the control circuit allows time for this transition. Thus the energy stored in the capacitance of the switches is returned to the source and load rather than being dissipated in the switching devices. This greatly improves the efficiency of the converter particularly when operating at high frequency. The unique topology of the converter provides other new and useful characteristics in addition to zero voltage switching capability such as operation at constant frequency with pulse-width-modulation for regulation, quasi-square wave output current, and the ability to integrate the magnetic elements with or without coupling.
