Title: Cylindre hydraulique avec piston et avec dispositif magnetique servant a determiner la position du piston
Inventor: CHRISTENSEN FINN DAMKJA ER
IPC: F15B15/28
Filed: 1987-04-14
Abstract: Afin d'obtenir une détermination fiable de la position du piston dans un cylindre hydraulique risquant d'être exposé à une forte gelée, on suggère de monter un composant magnétiquement sensible ayant la forme d'un transducteur à effet Hall dans un alésage ménagé dans la paroi du cylindre et à le placer entre un aimant annulaire permanent (17) et une feuille magnétiquement conductrice (14). On place au milieu de l'alésage un montant magnétiquement conducteur (16) et on bouche hermétiquement l'alésage vers l'intérieur du cylindre par un matériau non magnétique (19), tel que du laiton. Le transducteur à effet Hall (15) forme ainsi une partie d'un circuit magnétique fermé comprenant l'aimant permanent (17), le montant magnétiquement conducteur (16), le disque magnétiquement conducteur (14) et la paroi du cylindre hydraulique entourant l'alésage. Lorsque le piston dans le cylindre hydraulique fait face au capteur, un second circuit magnétiquement conducteur fermé se forme, lequel comprend l'aimant permanent, le montant magnétiquement conducteur, le piston et la paroi d'acier du cylindre. De ce fait, le champ magnétique au-dessus du transducteur à effet de champ est supprimé et la position du piston peut être enregistrée par des circuits de détection électriques appropriés reliés au transducteur à effet Hall.

Title: Prepayment metering system using encoded purchase cards.
Inventor: SLOAN JOSEPH W
IPC: G07F7/00
Filed: 1987-12-07
Abstract: A prepayment utility metering method and apparatus which uses encoded mag-stripe cards to transfer purchase information from the utility billing office to the customer's premises. The mag-stripe cards are read at the customer's premises by a microprocessor-controlled utility metering and control device which meters the utilities according to the amount purchased at the utility billing office. The value information encoded on the mag-stripe cards is comprised of the amount of the purchase coded in terms of number of shaft revolutions of the metering disk, a rate schedule for metering the value of the utilities consumed, and a special sequential password containing an encrypted combination of the consumer's account number, the consumer's site identification, and the sequence number of the current purchase. This encoding scheme for prepayment of utilities provides an effective and economical method of distributing utilities that prevents fraud and tampering. The present invention also includes a method and apparatus for providing an emergency credit to utility consumers when the prepurchased amount is exhausted. An emergency mag-stripe card is used to credit the user's account with a purchased amount of utilities adequate to tide the consumer over until the billing office opens on the next business day. The emergency mag-stripe card cannot be used more than once, and the credit amount in the meter must be replenished by a new purchase of utilities before the emergency card can be used again.

Abstract: A portable storage (4) unit has a pair of hollow, cylindrical-­shaped spools (78,79) loosely supported on a pair of cradles (80,81) within a frame (65). A pair of annular flanges (84,85,87,88) adjacent the ends of each of the spool surfaces engages stop plates (126,127) on the frame to retain the spools in position on the cradles when the frame is in both a vertical load and unload position and a horizontal storage and transport position. Drive units (3) for loading and unloading the spools preferably are similar, each including a pair of expanding mandrels (17,18) and a motor driven chain connected to one of the mandrels. The storage unit is placed on a carriage (6) which is located adjacent the mandrels of the drive units by material handling equipment. The carriage is moved horizontally toward the stationery mandrels until the mandrels are inserted within the spool interiors. The mandrels then are expanded securely gripping the spools thereon. The carriage platform then is lowered allowing the spools to lift off their supporting cradles enabling the spools to be rotated freely by the mandrels for loading and unloading the strip material on or off the spools. A storage unit is loaded with extruded tire tread material in the vertical position and then is placed in a horizontal position for subsequent shipment and storage reducing the formation of imperfections in the tread which occurs if the tread is aged in the vertical stored position.

Abstract: A process for heating elongate metal material (2), for example elongate aluminium, in stepwise passage through a plurality of series-arranged, separately controllable heating zones (A, B, C), for each of which an intended temperature is preset and monitored at a check-measuring point, the elongate metal material (2) is, after it has reached the intended temperatures, conveyed forward by the distance A + X for shearing off a block of length X and, after this block has been sheared off, conveyed back by the length A, A being the distance between the front end of the metal material located before the forward-conveying in the last heating zone (d) and the shears (3), the temperatures on the surface of the metal material at the check-measuring point of at least the first heating zone (A) and at a measuring point offset rearwards therefrom by the length L are detected immediately before the metal material is conveyed forward, with L >/= X. From these two temperature measurements, the temperature gradient is determined. Starting from this, that heating power is determined and applied which, after the forward-conveying by the length A + X and the back-conveying by the length A, gives again essentially the intended temperature at least at the check-measuring point of the first heating zone. The required heating power can, on the basis of these measurements, also be calculated for the next and/or further heating zones, for which the determination of a temperature gradient between the check-measuring points of successive heating zones can be helpful. <IMAGE>

Abstract: When an acceleration sensor is used, it is attached to a measured object to detect an acceleration applied to the object. The acceleration sensor includes a package (100, 600) having at least one chamber (A). A sensor element is disposed in the chamber and has a portion (4a) which vibrates in response to the acceleration. Damping liquid (700) is sealed within the package and has a quantity which allows the sensor element to be submerged in the damping liquid (700) and which allows a predetermined quantity of gas (800) to remain in the package. The gas (800) absorbs a thermally-induced volume change of the damping liquid (700). In the absence of the acceleration, a gas bubble is prevented from separating from the gas (800). In addition, the gas bubble is prevented from staying in the chamber (A).
