Title: Method of measuring low frequency signal shapes inside integrated circuits with an electron probe
Inventor: FAZEKAS PETER DIPL ING
IPC: G01R31/26
Filed: 1984-09-06
Granted: 1988-04-07
Abstract: A method for measuring a low-frequency signal progression at a measuring point of a specimen by use of an electron probe. A load on the circuit is kept as low as possible by employing a pulsed electron probe during a search of the measuring points. The pulsed electron probe may also be employed for actual measurement. By providing a pulse repitition frequency of the electron probe which is independant of the operating frequency of the circuit specimen, a phase shift of the primary electron pulses relative to the low-frequency signal progression is not necessary for real time measurement of the low-frequency signal progression.

Title: Device for the removal of solid particles from combustion engine exhaust gases
Inventor: DETTLING HUBERT
IPC: B03C3/41
Filed: 1984-12-22
Granted: 1988-08-11
Abstract: The exhaust gas cleaning system for a vehicle enqine includes a tube connected to the exhaust pipe, with a central support from end to end, carrying a set of equally spaced disc electrodes. These produce a corona discharge with the tube wall, which combines fine particles to form longer particles. Due to the speed of gas flow which is higher than 2.5 m/sec., the large particles are carried onwards to the end of the tube, using a swirling action. There, they enter a centrifugal separator where the clean gases are discharged through a tube one end, and the gases containing a high proportion of soot are discharged through another tube.

Abstract: A device for dispensing granular media or tablets in portions from a supply space therein is disclosed. The device comprises a casing having an outlet sealable by a normally closed spring-loaded tappet. The device also includes an actuating system located within a recess in the outer walls of the casing. The tappet emerges from an internal wall within the casing. The wall forms an internal shaft for supporting the tappet and spaces the tappet from the outer walls of the casing. The internal wall also forms a space between an outer walls and a supply space which is open towards the recess and allows for easy formation of the casing. The supply space has a lower portion from which there extends a duct which forms the outlet for the device. The tappet has an opening therethrough at a lower end thereof capable of being moved in front of the duct when in a dispensing position. The supply space is then sealed by an insert located within the lower portion of the supply space. The insert has a guide wall capable of isolating the supply space from the opening in the tappet when the tappet is in the dispensing position and wherein the actuating device slides within the recess and the casing walls to thereby move the tappet from its normally closed position to its dispensing position.

Abstract: In the combustion of chlorinated organic compounds, small quantities of polychlorinated dibenzo-p-dioxines (PCDD) and dibenzofurans (PCDF) can be formed in addition to the comparatively highly concentrated gaseous and particulate combustion products such as, for example, carbon monoxide, nitrogen monoxide, sulphur dioxide, sulphur trioxide, hydrogen chloride, hydrogen fluoride, soot and solids. PCDD and PCDF have a considerable potential for polluting the environment.   According to the invention, organic-chemical substances can be decomposed under defined conditions, so that, for example, toxic substances can be processed without polluting the environment. This is effected in an anaerobic atmosphere by means of a fluidised bed 3 and/or piston compressor 11, in which, for example, PCDD and PCDF are cracked. Such a process with the respective equipment can be used on site wherever polluting substances from the group indicated are formed. <IMAGE>
