Title: Method and apparatus for type IIB diamond sorting
Inventor: ROOS EDWIN HARM
IPC: B07B13/00
Filed: 1990-12-06
Abstract: Diamonds which are to be sorted are subjected to a varying magnetic field or to electromagnetic radiation chosen to generate eddy currents in type IIB diamonds. The diamonds can then be sorted into a type IIB fraction and an "other diamond" fraction on the basis of the level to which they are heated up by the eddy currents. Sorting may be achieved by employing infra-red detectors and fluid blast ejectors, or by dropping the diamonds onto the surface of a body of ice which captures the hot type IIB diamonds.

Title: Recovering a time-varying signal using multiple adaptive filtering algorithms
Inventor: BAKER JAMES C
IPC: H04L25/03
Filed: 1992-09-24
Abstract: For recovering symbols in a data packet (101), Fig. 1, (not shown), transmitted to a receiver (201), Fig. 2, (not shown), from a remote signal source (202) in a time-varying channel using multiple adaptive filtering algorithms, there is used an adaptive filter 203 responsive to a recursive least squares (RLS) filtering algorithm followed by a least-mean squares (LMS) filtering algorithm. The RLS filtering algorithm is used first for its fast training and fast recovery characteristics. The LMS filtering algorithm is used second for its low complexity and high stability characteristics. The switch between the RLS and the LMS filtering algorithms may be at a fixed point in time to ensure minimal filter complexity or may be adaptive responsive to the quality of an error signal (ek) processed in a coefficient determinator (307 or 309) to ensure maximum bit error rate performance and stability. <IMAGE>

IPC: F02M63/00
Filed: 1994-05-17
Abstract: A fuel-injection device for an internal combustion engine includes a stepped pump piston (29) movable in a cylinder bore (27) and defining therewith a driving chamber (35) and a pump working chamber (55), the latter being limited by an annular front face (53) at the smaller pump piston diameter. The chamber (55) is filled with fuel by being connected to a fuel supply line (21) before the device is actuated. The working chamber (35) which is at least indirectly defined by the larger end face (41) of the stepped piston (29) can be connected by a pressure line (37) containing a 3 port, 2 position valve (39) to a pressure line (13) or to a relief line (17). Opening of the pressure line (13) causes actuation of the piston (29) by the conveyance of a highly pressurised medium, located in a pressure reservoir, into the working chamber (35). A measured quantity of fuel admitted to the working chamber (55) is pumped through outlet openings (51) once the annular fuel (53) closes the supply line (21). <IMAGE>
