Title: Electron guns for cathode ray tubes
IPC: H01J29/48
Filed: 1988-12-02
Abstract: The gun comprises a cathode (C), a control grid (G), a first anode (A1) a second anode (A2) and a third anode (A3). Preferably a beam width limiting aperture (BL) is provided in the first anode (A1). In one example the current modulating voltage applied to the grid is 0 to -50V, the voltage applied to the first anode is +5kV, the focus voltage applied to the second anode is +500V, and the EHT voltage applied to the third anode is +25kV. A main focussing lens is formed by the second and third anodes, but the spacing of the first and third anodes is small so that the focussing effect is also substantially dependent on the voltage of the first anode. The field strength between the grid and first anode is high, which combined with the high A1 voltage produces a small crossover.

Title: Excess voltage protection circuit
IPC: H02H7/20
Filed: 1989-12-11
Abstract: An excess voltage protection circuit for a d.c. 
voltage supply has supply lines (10/13,11/14) for 
connection to a device to be powered. One of the 
supply lines (10/13) has a switching transistor (T1) 
connected in series in the line. A control circuit 
(15) is responsive to a voltage detector circuit 
(16) coupled with the supply line (10/13). When an 
excess voltage occurs the detector circuit (16) 
causes the control circuit to trigger the switching 
transistor to a non conductive state and thereby 
prevents exposure of subsequent circuitry to excess 
voltages. The switching transistor (T1) may be 
fabricated on an integrated chip by the resurf 
principle together with the control circuit (15) and 
the voltage detector circuit (16) employing 
semiconductor devices with reduced breakdown voltage 
with respect to the input voltage of the system.
Patent EP-0334616-A3 (EP)
Title: Method and system for personal identification
IPC: G06Q20/40
Filed: 1989-03-21
Abstract: The method and system of the invention utilizes a private 
key of a public-key cryptosystem key pair to encrypt a 
non-secret password into a digital signature. The password 
and the digital signature are then encoded and stored on a 
magnetic stripe or other memory device of the card. To effect 
a transaction, the digital signature on a received card must 
be shown to have been generated from the password on the 
received card. The password preferably includes a digitized 
photograph of the authorized cardholder which is capable of 
being displayed at the transaction terminal. This enables the 
operator of the terminal to verify the identity of the 
cardholder by visual inspection.

Patent EP-0375338-A3 (EP)
IPC: H01J61/52
Filed: 1989-12-19
Abstract: An apparatus (10) for producing high intensity 
radiation has electrodes (15,17) positioned within an elongated 
cylindrical arc chamber (12) across which an arc discharge can 
be established. Liquid is injected into the arc chamber to 
produce a vortex motion therein to form a cylindrical 
liquid wall adjacent to the chamber, which constricts the 
arc by cooling an outer periphery thereof. Gas is injected 
into the arc chamber to produce a vortex motion adjacent 
the cylindrical liquid wall. An exhaust structure actively 
exhausts the liquid and gas from the arc chamber to reduce 
turbulence and restriction of fluid. This permits 
attainment of higher flux densities in the arc, and/or 
extension of electrode life. Preferably, the liquid and 
gas are exhausted actively by means of an ejector pump 
which ejects pressurized liquid into the gas and liquid 
leaving the arc chamber. The ejector pump pressurizes the 
exhausted gas and liquid sufficiently to permit the gas to 
be separated and recycled back to the arc chamber, without 
requiring an additional compressor to increase gas 
pressure.
