Title: Independently actuated pressure relief system
Inventor: JOHNSON STEVEN H
IPC: F15B11/08
Filed: 1988-02-02
Granted: 1991-02-19
Abstract: INDEPENDENTLY ACTUATED PRESSURE RELIEF SYSTEM Abstract of the Disclosure A pressure relief system for the primary hydraulic system of a large industrial machine wherein the biasing force biasing one of the pressure relief valves is supplied by the pilot hydraulic control system of the machine.  A two-position valve is used to selectively change the biasing force in response to a temperature indicator.  The two-position valve couples and decouples the pressure relief valve to and from the pilot control system hydraulic pump and the pilot hydraulic system sump.  If the pressure relief valve is in communication through the two-position valve with the pilot hydraulic fluid sump, the biasing force is reduced against the pressure relief valve and the pressure in the primary hydraulic system opens the pressure relief valve and directs hydraulic fluid to the primary hydraulic fluid sump.

IPC: C04B22/14
Filed: 1988-06-17
Granted: 1992-03-17
Abstract: ABSTRACT OF THE DISCLOSURE   This invention is directed to a process for the chemical stabili-zation of heavy metal bearing dusts and sludges.  A preferred use for such process is the treatment of dust from an electric arc furnace (EAF).  In the production of steel by the electric arc furnace process, a by-product thereof is the generation of EAF dust.  Such dust, by virtue of the pres-ence of such elements as cadmium, hexavalent chromium and lead, is classi-fied as hazardous waste by U.S. Environmental Protection Agency (EPA).  The present invention is directed to a process for the chemical stabilization of the inorganic EAF dust to render the hazardous constituents thereof virtually immobile.  Such process is based on the pozzolanic reaction of materials containing anhydrous alumino-silicates which, in the presence of lime, water and chemicals, adsorb and/or physically entrap the heavy metals present in EAF dust into a calcium-alumino-silicate matrix.

Title: Bulk avalanche semiconductor laser
Inventor: RAGLE LARRY O
IPC: H01S5/32
Filed: 1988-10-12
Granted: 1992-01-21
Abstract: ABSTRACT OF THE DISCLOSURE            A bulk semiconductor laser which uses optically triggered avalanche conduction to initiate the lasing action in the bulk.  A semiconductor block has electrodes coupled on opposing sides and a high voltage is applied across the electrodes which is less than the voltage required for avalanche breakdown.  The block is irradiated with light which produces charge carriers in the block to initiate avalanche conduction, which results in a large number of charge carriers. The charge carriers recombine to generate a second amount of electromagnetic radiation.  This radiation is reflected back into the block on two opposing sides, thus resulting in a laser emission.
