Patent NL-7408487-A (NL)
Inventor: VERNOOY BURTON
IPC: G01M3/00
Filed: 1974-06-24
Abstract: A pipeline pig is provided with at least two wheels mounted thereon to roll along the inner wall of the pipeline. Pulses are generated as each wheel turns a predetermined revolution such as by a magnet carried by each of the wheels for movement past a magnetic flux responsive switch carried by the mechanism mounting the wheels. Thus, as each wheel revolves, its respective magnet moves past the switch to actuate it and thereby provide a pulse responsive to the distance moved by the pig. Each of the flux responsive switches is connected to a circuit means for providing an output responsive to the largest count obtained from the individual flux responsive switches over an increment of travel of the pig.

Patent NL-7702430-A (NL)
Title: Electrostatic precipitation of dust or liq. droplets from gases - with assistance from secondary liq. fog
IPC: B03C3/53
Filed: 1977-03-07
Abstract: The particles are sepd. from the gas as it passes between two electrodes, one earthed and one at a high voltage. Sepn. efficiency is increased by mechanical atomisation of liq. to form droplets in the gas and films running down the electrodes. The secondary liq. is sprayed in form of relatively coarse droplets and is atomised to form a fog of fine droplets by the high-voltage electrode. The earthed and high-voltage electrodes are arranged to create a simple (one-way) electric field between them only the high voltage electrode acting as emitter-ioniser. The gas-borne contaminants are sepd. by the combined effects of the electric field from the electrodes and the secondary liq. fog, whose particles have the same charge as the high voltage electrode. The slurry is collected and removed from the earthed electrode. Electrostatic prodn. of the secondary fog eliminates the need for spray nozzles with very fine, easily blocked passages. The design of the electrodes prevents formation of a second opposing field which would result in redispersion from the earthed electrode.

Patent NL-9302221-A (NL)
IPC: E05B65/12
Filed: 1993-12-21
Abstract: In order to prevent a car from being broken into or stolen, the invention proposes a security device which is formed by a lock fitted slidably in each door of the car, which lock is connected to and driven by a drive element (12a, 12b). The lock can be slid by means of said drive element so that it engages with or is disconnected from an opening disposed in the frame of the car door in question. For this purpose, the drive elements are accommodated in an electrical circuit which also contains the voltage supply of the vehicle and a switch element. The security device can be turned on by means of said switch element, in order to lock all car doors securely. This switch element is therefore situated outside the passenger compartment. In another embodiment the security device is suitable in particular for the loading door of a lorry, which door has two locking rods (31,34; 32,35) which are axially slidable in opposite directions to each other, and which each interact with an opening disposed in the doorframe thereof. This embodiment is distinguished by the fact that each locking rod is connected to a drive element (12a, 12b), which drive elements are disposed in opposite directions in order to move the two rods simultaneously in opposite directions. The two drive elements are again accommodated in a control circuit (50) containing a voltage supply and a switch element. <IMAGE>
