Abstract: A data processing system, method and program are disclosed, for managing a public key cryptographic system. The method includes the steps of generating a first public key and a first private key as a first pair in the data processing system, for use with a first public key algorithm and further generating a second public key and a second private key as a second pair in the data processing system, for use with a second public key algorithm.  The method then continues by assigning a private control vector for the first private key and the second private key in the data processing system, for defining permitted uses for the first and second private keys.  Then the method continues by forming a private key record which includes the first private key and the second private key in the data processing system, and encrypting the private key record under a first master key expression which is a function of the private control vector.  The method then forms a private key token which includes the private control vector and the private key record, and stores the private key token in the data processing system.  At a later time, the method receives a first key use request in the data processing system, requiring the first public key algorithm.  In response to this, the method continues by accessing the private key token in the data processing system and checking the private control vector to determine if the private key record contains a key having permitted uses which will satisfy the first request.  The method then decrypts the private key record under the first master key expression in the data processing system and extracts the first private key from the private key record.  The method selects the first public key algorithm in the data processing system for the first key use request and executes the first public key algorithm in the data processing system using the first private key to perform a cryptographic operation to satisfy the first key use request.

Title: Fabry-perot modulator
Inventor: WHITEHEAD MARK
IPC: G02F1/015
Filed: 1991-05-24
Granted: 1996-08-27
Abstract: An asymetric Fabry-Perot (FP) modulator includes a quan-tum well structure having wider (approximately 150.ANG.) than usual (about 100.ANG.) wells. The FP cavity has a resonance at a wave-length of an excitonic absorption peak of the QW structure. Al-though the maximum change in absorption under applied bias is less with 150° wells than with 100° wells, the characteristics of the electroabsorption are also altered, with the result that the lar-gest change occurs at the wavelength of the band-edge el-hhl ex-citon at zero bias. Absorption can be reduced by biasing the QW and hence the AFPM can have a normally-off (zero bias, zero ref-lectivity) characteristic. Such an arrangement makes possible higher contrast modulation and/or lower operating voltages. The FP modulator may be used in SEEDs.

Title: Fuel fired burners
Inventor: PALMER-JONES ROLAND VINCENT HO
IPC: F23D14/30
Filed: 1995-06-15
Granted: 1999-04-06
Abstract: A fuel fired burner is provided for receiving a premixture of fuel and air. A ceramic flame support extends across the burner chamber (2) and has a plurality of elongate slots (62) through which the fuel and air flows.  Each slot has a narrow constant dimension portion (84) that opens into a wider constant dimension portion (86).  The outlet end of the latter portion opens into a short diverging outlet (87).  The arrangement is such that when the burner is operating within a given heat output range, the burner flame can move between the upstream and downstream ends of the diverging outlet (87) to seek stabilisation as the heat output changes within that range, without retracting into the slot upstream of the diverging outlet (87). With this burner the likelihood of resonant combustion noise occurring is alleviated or reduced.
