| A small fuel cell (10) powers a portable electronic device (12) and contains a fuel reservoir (14) and a device (16) that measures the amount of liquid fuel (18) that is in the reservoir. The fuel cell operates on hydrogen that is obtained from a liquid hydrocarbon fuel, such as alcohol or other hydrocarbons. The liquid fuel is typically converted into hydrogen by a reforming process. The reservoir that is connected to the fuel cell has an indicia (19) that is readable by a human user of the portable electronic device, for measuring the amount of liquid hydrocarbon fuel that is present in the reservoir. Typically, the indicia consist of a sight glass, a capacitive element, a resistive element, a transparent portion of the reservoir, a float, or an acoustic transmitter coupled with an acoustic receiver. | ||||||
| 185 | SYSTEM FOR DETECTING AND RECORDING DISCHARGES OF WASTE HYDROCARBONS OF A SHIP | EP01945353.9 | 2001-06-26 | EP1313056A1 | 2003-05-21 | AROCENA YARZA, Miguel Angel |
The system is meant to detect and record in real time any irregular dumping occurring during the operation of any ship, both of waste hydrocarbons stored in the bilge (1) of the ship and of residues from cleaning the crude oil tanks of oil tankers. The system is based on providing two level probes (13-14) to detect the upper level of the layer of waste hydrocarbons (3) and its bottom layer, which floats on a volume of waste water (2) contained in the bilge (1), as well as optionally a third probe (16) may be provided in a tank (10) for storage of waste hydrocarbons separated from the waste water, so that the data obtained from these probes are recorded and stored by a multiparameter recording station (15) which, in combination with a computer system of the port allows to know the variation in volume of waste hydrocarbons during the operation of any ship. Oil tankers are provided with a flow meter (18) in the pipe (19), which detects the data corresponding to residues obtained from cleaning the tanks (17) (see Figure 2), with the data obtained by this flow meter being sent to the same recording station (15) in order to know the variations in volume of these residues. |

| An apparatus and method for detecting lubricant reservoir (14, 16) levels, particularly in bearing sections for downhole mud motors, is revealed. This allows rig personnel to more exactly ascertain the remaining bearing life of the assembly. In one embodiment, the assembly is pulled out of the hole and comprises of a signal source. A hand-held device is placed next to the bearing housing and the location of the strongest signal is a direct measurement of the position of the floating piston in the lubricant reservoir. The rig personnel can then readily obtain a level reading on the fluid level in the reservoir. An alternative design is also revealed where the position of the floating piston is sensed in real-time by receivers mounted at spaced locations in the lubricant reservoir. The position of the floating piston is thus detected by the receivers and sent to the surface, generally through the measurement-while-drilling (MWD) sub, so that rig personnel at the surface know at any given time the position of the floating piston and, thus, the remaining lubricant level in the reservoir. The signal source can be a magnetic component mounted in the bearing housing reservoir area where the surrounding components are nonmagnetic such that the receiver responds to the magnetic field created by the magnetic signal source. The signal source can also be powered by a stored electrical supply which can generate through a signal source a signal which can be measured, either over the air or by a hand-held receiver held by rig personnel, or by a connection to the bearing housing for a direct reading of the signal generated. | ||||||

A length measuring apparatus employing a magnetostrictive delay line according to the present invention includes a drive coil (4), a receiving coil (3) provided on an outer periphery of the magnetostrictive delay line (1) over the whole length measuring range thereof, the magnetostrictive delay line (1) uniformly magnetized in its length direction, and a short-circuit ring (2) disposed over an outer periphery of the receiving coil (3). Ultrasonic vibration (C) is generated in the magnetostrictive delay line (1) by using the drive pulse (A) applied to the drive coil (4). A pulse current (B) generated in the receiving coil (3) is detected when the ultrasonic vibration (C) is propagated in the magnetostrictive delay line (1) and passes by a position where the short-circuit ring (2) is disposed. A position of the short-circuit ring (2) is measured based on a time from generation of the drive pulse (A) to generation of the pulse current (B) in the detection coil 3. |

A level indicating assembly for use in a tank (11) mounted in a vehicle, such as a recreational vehicle or boat, includes a fitting body (20, 21) for mounting the assembly in the top (14) of the tank, and probes (17-19) extending through the body into the tank. At least one of the probes has a hollow probe shaft (30) which is of a flexible material such as flexible pvc. One of the probes provides an "empty" (64) indication for the tank, while the other probes provide a "full" (66) indication, and a mid-level (65) indication. A socket (54) or like element with a knock-out plug (55) optionally provides a vent in the fitting body. During installation the position of the probe shafts with respect to the fitting body are adjusted, and any unneeded portion of the probe shaft above the shaft fitting is cut off. |

| Dispositif permettant d'effectuer une discrimination entre des fluides et d'améliorer la sécurité des réchauds à kérosène (10) en faisant la différence entre le kérosène approprié aux réchauds et des matériaux plus volatiles tels que l'essence. Le réchaud au kérosène est conçu de manière à empêcher son remplissage par toute autre structure que la structure de discrimination de fluide associée de manière fonctionnelle (28). Un flotteur (56, 156) comprenant des dispositifs d'actionnement magnétiques ou photosensibles est calibré pour permettre ou arrêter le fonctionnement d'une alimentation en kérosène (36) en fonction de la position du flotteur dans le fluide. Un fluide moins dense que le kérosène, tel que de l'essence, provoque l'enfoncement du flotteur dans le fluide et, par conséquent, l'arrêt de l'écoulement de liquide vers le réchaud au kérosène. | ||||||
