Title: Warning device for safety fuse in AC circuit - has series circuit of capacitor, gas discharge lamp and limiting resistor in parallel with fuse
IPC: H01H85/30
Filed: 1975-03-21
Abstract: Signal annunciator for safety fuses. A load (6) is fed via two parallel diode circuits from an alternating current source. The diode circuit consists of a series circuit of one diode (1) and a fuse (2) which is intended to protect the entire circuit. The warning device is connected in parallel with the diode and fuse circuit. It consists of a capacitor (5) a gas discharge tube (3) and a limiting resistance (4).

Title: Seismic exploration method with enhanced survey results - has sensor array for sensing response of seismic horizons to emitted seismic waves
IPC: G01V1/00
Filed: 1978-02-06
Abstract: The method of seismic exploration includes sensing the response of the seismic horizons to emitted seismic waves, by using a sensor array of aperture of a number of seismic sensors.

IPC: E04G25/06
Filed: 1990-03-26
Abstract: For supporting of formwork in constructing buildings, use is made of steel post shores (props) having a pin 15 with recessed areas thereon. When the prop has to be brought from the loaded to the unloaded position, such pin is changed of position in the prop so as to allow the inner tube to be lowered within the outer tube of the prop. The invention provides a new pin-design such that after assembling the prop it can be clearly seen wether the pin finds itself in the correct position or not. For that purpose, use is made of a pin (15) having a recess (27) and a flattened portion (29); by axial displacement of the pin this portion rests (in fig.2,10) on ring (12) or on inner tube (3) under changing its angular position, which is well visible for the user. Alternativily the cylindrical pin (35) of fig. 4 has two cams (39, 41) resting on ring 12; by axially displacing this pin, it will rotate over 90 DEG  and the inner tube (3) will be lowered in the outer tube (1), which position is clearly visible for the user. <IMAGE>
