Title: Electrolytic separation of metals
Inventor: LEWIN ROBERT GLYN
IPC: C25C3/26
Filed: 2002-12-05
Abstract: A process for the separation of metals, the metals being, comprised as the metal oxides in a mixed oxide sample, comprises (i), adding the mixed oxide to a molten salt electrolyte and cathodically electrolysing the oxide, the potential of the cathode being controlled so as to favour oxygen ionisation over deposition of metal from the cations present in the molten salt, and the applied potential difference being such as to facilitate selective reduction of one metal oxide at the expense of other metal oxides; and (ii) separating the metal from the remaining metal oxides. The process is applicable to mixed oxide samples comprising mixtures of two or more metal oxides, and is particularly useful for the separation of metals of the transition, lanthanide and/or actinide series comprised in mixed oxide samples. A particular application is in the separation of zirconium and hafnium comprised in mixed zirconium and hafnium oxides, the removal of hafnium facilitating the use of the zirconium in fuel cladding for use in the nuclear power industry.

Title: Method and apparatus for encrypting data
Inventor: HUTTUNEN ARI
IPC: G06F21/88
Filed: 2003-02-01
Abstract: A method of securing data on an electronic device (eg a PDA) comprising allowing a user of the device to select one of two operating modes - an encryption only mode (Mode 2) and an encryption / decryption mode (Mode 1). Mode 1 requires the device to have access to a user passphrase (which can be a password, biometric data or another form of key), whilst Mode 2 does not require access. Mode 1 is a transparent encryption system. The method of securing data comprises: pre-generating a plurality of symmetric keys for use with a symmetric cipher; storing the keys in a memory of the device in plaintext form and in encrypted form, the encrypted form being protected by a passphrase; encrypting a block of data using one of said symmetric keys; storing the encrypted block and destroying the plaintext version; destroying the plaintext version of the key used to encrypt the block and repeating the last 3 steps for each subsequent block to be encrypted. The encrypted blocks are then secured until such time as a user enters the passphrase to unlock the encrypted versions of the used symmetric keys.

Title: Testing an EEPROM utilising an additional select transistor and test line
Inventor: ENELAND JOHAN D
IPC: G11C29/00
Filed: 2004-03-26
Abstract: An EEPROM cell is provided with storage transistor 10, a select transistor 12 and an additional select transistor 14 which facilitates a faster test of the EEPROM cell by writing a predetermined value to the cell when the write test data line WTD is asserted. The additional select transistor applies either a value on test bit line TBL, as shown in cell 0, or a value on corresponding bit line BL1, as shown in cell1, to write data into storage transistor 10 when the write test data signal is asserted. When testing the EEPROM a first test applies a "1" to the test bit line and a "0" to all bit lines and asserts write test data signal to write the "1"'s and "0"'s into the EEPROM cells; the data is then read out to verify the data in each cell. A subsequent test applies a "0" to the test bit line and a "1" to all bit lines and asserts the write test data signal to write "0"'s and "1"'s into the EEPROM cells; the data is then read out to verify the content of the cells. This test thereby verifies the write and read operation of each cell whilst reducing the time required to write the data into each cell and hence reduce the overall time required to test an EEPROM.
