Patent GB-2139026-A (GB)
Title: Signal processing
Inventor: COOKE-YARBROUGH EDMUND HARRY
IPC: G01N29/06
Filed: 1984-04-12
Abstract: A method of processing analogue electrical signals consisting of a base level component with a varying component superimposed upon it, comprising the operations of determining the base level component of an input analogue signal of the said form, digitizing it, storing it, reconverting it to an analogue form and subtracting the reconstituted analogue signal from the input analogue signal, and then digitizing the remaining signal, the digital step level of the digitization of the base level component of the input analogue signal being greater than that of the digitized remaining signal. The method is applied to ultrasonic detection of discontinuities in a specimen 1 subjected to alternating stress, wherein it is required to remove from the received echo signal the steady state component and other constant errors, and to isolate the stress-related component. Initially the steady state echo (no stress applied) is coarse digitized (8 bits) by digitizer 8 and stored 33. Subsequently the analogue version 34 of this is subtracted 32 from the received echo, the resultant being fine digitized (8 bits) and correlated 9 with the stress as indicated 6, 10. Signals in corresponding time slots are added 11 and stress-sensitive discontinuities will cause accumulation at corresponding memory positions. <IMAGE>

Title: Combustion initiation system employing hard discharge ignition
Inventor: PATE RONALD C
IPC: F02P9/00
Filed: 1985-02-26
Abstract: A system for initiating combustion of fuel, especially for internal combustion engines, employs a very rapid, intense high power electrical breakdown arc to increase the rate of combustion and thereby reduce the need for advanced engine timing. The use of a distribution circuit (46) which has exceptionally low inductance and resistance results in the rapid electrical breakdown and coupling of at least 50% of stored pulse energy to the breakdown arc channel within the first half period of the discharge current cycle. The resulting arc discharge effects detonation of the fuel mixture through the cooperative effects of photolysis, supersonic hydrodynamic shockwave and high temperature thermal plasma. High voltage pulse generation distribution and switching circuits (Figures 29-36) are provided. Several discharge electrode geometres and closely coupled pulse forming networks for the discharge device are disclosed.
