Title: Rapid decarburiztion steel making process
Inventor: MELMAN STEWART K
IPC: C21C7/068
Filed: 1985-03-13
Granted: 1990-04-23
Abstract: Rapid decarburisation of a steel melt to a predetermined carbon content comprises injecting oxygen and powdered lime into a steel bath containing at least 0.1% C while simultaneously injecting oxygen and inert gas into the melt from below the surface.  The amount of top injected oxygen is 0.5-3.0 times the amount of bottom injected oxygen until the carbon level drops to at least 0.1% but not more than 0.5% greater than the predetermined carbon level.  The top injection of oxygen and powdered lime are discontinued and oxygen and inert gas are blown exclusively from below the melt to decarburise the melt until the predetermined carbon level is reached.

Title: Apparatus for the acceleration of solid particles
Inventor: BOCK ANDRE
IPC: C21C5/46
Filed: 1985-05-13
Granted: 1993-02-26
Abstract: An acceleration nozzle for particles entrained in a carrier gas comprises a first central nozzle having a first diverging cross-section, and an extension nozzle section extending from the first nozzle. The extension nozzle section has a flare or diverging angle which is greater than that of the first acceleration nozzle. The nozzle extension is surrounded about its mouth or opening by a second nozzle forming a casing or housing therearound; the second nozzle being connected to a source of gas. In a preferred embodiment, instead of utilizing two distinct gas sources to supply the first acceleration nozzle and the second "housing" nozzle, a portion of the gas passing through the acceleration nozzle may be diverted by means of slits built into the latter. The slits act as a separator of the gaseous phases and solid particles, and prevent the solid particles from penetrating the second nozzle. Acceleration nozzles of the present invention are typically used for delivering carboniferous powdered materials into a steel bath.

Title: Vibration type measuring apparatus
Inventor: GOODIER PETER T
IPC: G01L1/10
Filed: 1987-07-01
Granted: 1992-06-01
Abstract: The invention relates to a weight measuring apparatus utilizing a vibration type force sensor having a greatly increased Q and being inexpensive and easy to manufacture. The force sensor includes a single vibratory beam or a pair of vibratory beams, which oscillate at a particular measurement frequency related to the stress applied to the sensor by a weight. A rotational mass is coupled to a nodal point of the vibratory beam at the measurement frequency, and greatly influence the frequency at which the beam will vibrate. As a result, the tolerances for manufacture of the force sensor are greatly relaxed, and the pendulum-like movement of the rotational masses for a double-ended tuning fork type sensor tends to override any mismatch between the two parallel vibratory beams.

Abstract: The power source comprises a first rectifying part (10) for converting external AC power into DC power, transformer (T1), a second rectifying part (20) for converting power induced to the second coil of transformer (T1) into DC power and inputting magnetron, a first feedback part (30) for dividing and feedbacking a voltage detected by a current sensing transformer, a PMW controller (50) for outputting switching control pulses to adjust output voltage using feedback voltage of the first and the second feedback parts (30,40), and a switching part (60) for switching for the operation of a transformer (T1) and controlling a voltage inputted to the magnetron according to output switching pulses of the PMW controller (50).
