Abstract: The invention relates to a high sensitivity fault current protection switch, responding to any current, which is used particularly in domestic electrical installation technology and consumer networks. The circuit is used for the detection of fault currents of any wave form and for the detection of low resistance connections between the neutral and protective earth lines in the load. In this case, a frequency generated by a clock generator (1) is fed to the secondary winding (3) of a summing current transformer (2), the output of which is connected to a voltage divider (6), by means of which the clock current is made symmetrical. The pulsed signal is passed to a comparator circuit (7, 8) via a winding tapping (4), the pulsed signal being compared with in each case one reference voltage. If the signal is too high and/or too low, the comparators (7) and/or (8) switch on, thus activating the trip relay (12). An RC element (10) with a downstream comparator (11) is used for intercepting parasitic interference peaks. <IMAGE>

These regions (13) are electrically connected to substrate conductors (2, 3) in a simple and reliable manner by a metallization layer (23) in the apertures (20) without rendering a significant area of the detector non-sensitive to radiation imaged onto the upper surface of the body (11). At least the back surface of the detector body (11) has a passivating layer (17) at least over the area around and between the apertures (20) to enhance detector element performance, and this back surface is secured to the circuit substrate (1) by a layer (21) of electrically insulating adhesive. The main body part (14) is connected to a substrate conductor (4) by metallization (24) at a surface portion which is outside of the area of the back surface between the apertures (20). Using such a securement, ion-etching and connection technique, a closely-packed array of high performance detector elements (10) can be obtained on the circuit substrate (1) with a spacing of 100 micrometres or less between adjacent apertures (20).

Abstract: This invention is concerned with the high speed printing of a line of text on a sheet in very accurate registration with an edge of the sheet or another feature (for example an existing print line) on the sheet. The sheet is fed without pre-registration on to a track (10, Figure 1) which passes the printing station (20). A detector (16) adjacent the track senses the arrival of the edge or some other feature of the sheet and a printing control means (14) responsive to the detector signal initiates the firing of the printing hammer (22) when the print line reaches the printing station, a registered operation being thereby effected without stopping the sheet. The detector signal may start the operation of a counter (70, Figure 4) and a firing signal is sent to the hammer control circuit (100, 102, 104) when the count reaches a value dependent on the distance between the detector and the point at which the printing operation takes place and (unless the new print is to be in alignment with a detected print line) also dependent on the distance on the sheet between the edge or feature detected and the position at which the new print is to appear.

Abstract: Thermal waves which may be used for imaging in thermal-wave microscopy, are generated in a sample (20 through local periodic heating by impinging an intensity modulated beam (22) of energy on a portion of the heated area on the surface of the sample (20). A laser probe beam (24) is focused on a portion of the heated area on the surface of the sample (20) in a manner such that the laser beam (24) is reflected from the surface. The angular displacement of the reflected beam, resulting from the local angular change in surface conditions of the sample (20) due to the thermal waves, are monitored by a split or quadrant detector (26). The displacement of the reflected beam is used to detect the thermal waves.
