Title: Gas discharge lamp drive circuitry
Inventor: AARONS DAVID JOHN
IPC: H05B41/295
Filed: 2002-12-31
Abstract: An apparatus and method for controlling the operation of a gas discharge lamp, for example a fluorescent lamp, metal halide (HID) lamp, low or high pressure sodium vapour lamp, comprises an electronic circuit 1 for controlling the gas discharge lamp 40. The electronic circuit includes a pulse generator 18 for generating a high frequency pulse train that is applied to the electrodes 1L-4L of the lamp to light the lamp, and a controller 17 for controlling the applied frequency of the pulse train. The controller varies the frequency of the pulse train within an upper frequency band during a first mode of operation for striking the lamp, and within a lower frequency band during a second mode of operation for running the lamp once struck. In the first mode the frequency of the pulse train is scanned downwards until the lamp strikes. In the second mode the frequency of the pulse train is scanned downwards until the lamp provides a desired output.

Title: Controlling the strength and direction of detonation of an explosive charge in a warhead
Inventor: ARNOLD WERNER
IPC: F42B12/32
Filed: 2006-06-22
Abstract: A compensating volume in the form of a cavity 2 is arranged inside the explosive charge 1 of a warhead. The warhead has different ignition devices of which one ZK2 is suitable for the detonation initiation and the second ZK1 effects a deflagration or mechanical breakdown of the explosive charge. Detonation cords 3 extend from the deflagration initiator ZK1 and surround the cavity 2. Upon deflagration initiation or mechanical breakdown the cavity 2 absorbs the broken-down explosive charge particles and fragments 10. In this way the strength of the detonation can be controlled and, by further refinements, its direction also. In a second embodiment, the region between the compensating volume 2 and the casing 4 of the warhead is divided into a number of sector-shaped compartments (8,Fig.9) which are filled with liquid explosive whereby each sector (8,Fig.9) has at least one passage (9,Fig.9) to the compensating volume 2. In a third embodiment, an expansion means is provided for forcing part of the explosive into the compensating volume 2 to render it incapable of ignition, before detonation is initiated, so as to adjust the force of the explosion.
