Abstract: Instead of remotely controlling the motor's speed from a device in the handle of the extension tube of a vacuum cleaner, where the device is connected by electric leads in the extension tube to the motor, it is proposed in this apparatus that an optical motor speed control is used, i.e. that a light source (13) is fitted in the vacuum cleaner and via optical leads (14,15) run along the extension tube (11) communicates with a filter (12) placed in the tube's handle, by means of which the light illumination to a photo resistor in the vacuum cleaner is varied, thereby changing the effect of the motor.<IMAGE>

Abstract: The electronic fuse for a projectile comprises a radar emitter (2) having a resonant cavity (1) and a directional antenna (3). The presence of foreign bodies in the radar beam produces a Doppler effect which is detected by a circuit (5). This circuit (5) controls the modulation of the radar beam by means of two VHF oscillators (F1, F2) and the influence of the foreign body upon the modulated radar signal is analysed by the circuit (5) to determine if the foreign body corresponds to the target of the projectile or whether they are foreign bodies located accidentally on the trajectory of the projectile, for example, birds, droplets or micro-droplets of water. When the circuit (5) detects a signal corresponding to a motionless body of large dimensions, or a land, water or snow surface, it causes the firing of the projectile at a predetermined distance from the object.

Abstract: A worm press for mechanically separating liquid/solid mixtures comprising a feed region and a pin-barrel pressing region. The worm has at least one flight, each of which flights is interrupted so as to enable the flight to pass the stationary pins in the pin-barrel region. The downstream ends or points of the worm flight portions formed by the interruptions are specially shaped in order to increase considerably the strength and service-life of the highly stressed points. This is achieved by reducing the size of the thrust flank, so that the flank subtends an angle of from 20 DEG  to 50 DEG  relative to the line perpendicular to the worm axis. Desirably, the thus-angled profiled tip region of the flight portions are interchangeable.

Abstract: A current differential pilot protective relay apparatus for multi-terminal high-voltage, three-phase alternating current transmission lines. The pilot protective relay system provides comparison, at each terminal of the transmission line, of the currents flowing on each phase of the three-phase transmission line at each terminal thereof. A novel scheme of summing the current-derived signals at one terminal reduces the number of receivers and transmitters necessary to send the local signal from each terminal to all of the other terminals. Instead, the current-derived signals are summed at one of the terminals and the sum signal is then transmitted to each of the other terminals.

Abstract: A device for detecting the slag level in a molten bath comprises a measurement probe (2) provided on the probe with an antenna (8) for picking up hum in particular mains hum, in the vicinity of the antenna. A hum detector is connected to the antenna (8). Antenna (8) may be an exposed metal rod (as shown) protruding from the end of the probe (2) or it may be constituted by the wires of a temperature measuring thermocouple. The hum detector is arranged to compare the signal picked up by the antenna as it is moved by stepping motor (3) with constant velocity towards molten bath (1) with an alternating voltage related to the mains frequency only at the zero crossings of the alternating voltage. If the antenna signal and alternating voltage correspond with each other during a predetermined number of zero crossings an output is produced indicating mechanical contact of antenna (8) with the slag layer and which causes stepping motor (3) to stop. The number of steps moved is indicative of the slag level. The probe may include an inductor for detecting conventionally slag/metal interface. <IMAGE>

Abstract: The invention relates to a method and an arrangement for measuring the properties, particularly the degree of compaction of a stiff compactable mass such as fresh concrete, to be cast or a similar soil mass. In order to make the control of compaction more effective, gaseous pressure fluid is blown through the mass during the compaction of the mass, simultaneously, observing increases in the pressure of the gaseous pressure fluid in the surface portions of the mass due to increased flow resistance. The pressure fluid is blown through an opening formed in a wall adjoining the mass to be compacted and by means of a source of pressure fluid connected to the opening. Changes in the flow resistance are measured by means of a measuring device.
