Abstract: In impulse magnets, the armature is moved by a magnetic coil and is held in position at the end of its stroke by a permanent magnet. The armature is brought to the position at the end of its stroke by an impulse-shaped current flow in the magnetic coil (31) and is brought back to its original position by a current flow in the opposite direction. In order automatically to generate an impulse-shaped current flow on switching on, and an impulse-shaped current flow of opposing polarity on switching off, a circuit is proposed according to the invention which has two parallel series circuits of in each case two controllable electronic switch elements (19, 29 and 26, 27), between which the magnet coil (31) is located. A storage capacitor (25) is located in parallel with one of these series circuits (26, 27). A timer (32) and a control part (33) are further provided. The switch elements (19, 29 and 26, 27) are driven by the control part (33) on switching the impulse magnet on and off such that the current flows through the magnet coil (31) in the respective direction. The impulse duration of the current flow is governed by the timer (32) on switching on and by the discharge time constant of the storage capacitor (25) on switching off. <IMAGE>

Abstract: A sealing assembly for sealing the expansion gap between adjacent sections of a structure has elongated elastomeric pads (2, 24) laid end to end along the length of the gap with a groove (6) in at least one of the end surfaces (4) of each pad for containing a flowable sealant (in Fig. 7 the abutting end surfaces of the pad are shown spaced apart for clarity). 
     In order to achieve a seal which satisfactorily prevents access of debris and liquid into the expansion gap, while being easily formed after the pads are mounted in place, the groove has an inlet port at the top edge of the end surface through which the flowable sealant may be injected e.g. from a container (48), an intermediate sealing portion (12) for housing the sealant (46) to prevent debris and liquid from passing between the end faces, and a vent portion (22) communicating between the intermediate sealing portion (12) and the top edge of the end surface (4), so that sealant emerging from the top of the vent portion will indicate that the intermediate sealing portion has been filled. The other pad (24) may have a tongue which projects into, but does not fill, the groove (6), or may have a groove corresponding and opposed to the groove (6). The sealing portion (12) includes a length at the bottom edge of the endface (4), at which the sealant contacts the structure section.

Date Apr. 16, 1981.An electronic control and regulating system for AC-operated appliances, especially universal motors and with symmetrical phase control. The control circuit includes among other things an inductive current-voltage converter 9, the primary side 8 of which is connected to the load current circuit and in which, in addition to the converter function, the inductivity of the secondary winding 10 is used and becomes a component of a resonant circuit 20 which is tuned approximately to the frequency of the AC voltage source. The feedback variable of the control system is formed by the resonant circuit voltage, i.e. the resonant circuit impedance, which depends not only on the magnitude of the load current but also on the phase angle of the load current. This quasi-resonance effect makes possible a direct influence of the trigger circuit which consists customarily of a trigger capacitor 13, a load resistor 11 and a trigger diode 15 and is possible without excessive use of additional circuit elements.
