Abstract: On mesure les constituants des produits laitiers à l'aide de rayons infrarouges ayant au moins deux longueurs d'ondes spécifiques comprises entre 700 et 1200 nm et un trajet optique spécifique compris entre 1 et 15 mm. L'une des longueurs d'ondes spécifiques peut avoir une corrélation élevée avec la composition d'un constituant d'un objet tandis que l'autre présente une corrélation rapprochée, mais de préférence elles présentent toutes les deux une corrélation élevée. On illumine un objet avec de la lumière aux deux longueurs d'onde spécifiques, et l'on mesure la quantité de lumière traversant ledit objet afin de déterminer l'absorbance de lumière de ce dernier, et ainsi d'évaluer la composition de l'objet à l'aide d'une formule de double régression. La mesure s'effectue au moyen d'un capteur qui reçoit les rayons infrarouges proches provenant d'un système optique à interféromètre de Michelson par l'intermédiaire d'un filtre spectral et d'un échantillon dans une cellule à échantillons, afin d'en convertir le signal d'entrée en sa grandeur électrique et de calculer l'absorbance de lumière de l'objet. On a également prévu un dispositif amplificateur de l'absorbance de lumière, un dispositif de conversion numérique de l'absorbance amplifiée de lumière, et un dispositif de commande des signaux électriques ainsi convertis.

Abstract: Un circuit d'évaluation pour capteurs de position d'étrangleurs différentiels comprend les sous-groupes suivants: a) un premier raccordement de sortie (A1); b) un premier oscillateur (OSZ1) qui applique une première tension alternative au premier raccordement de sortie (A1), cette première tension alternative ayant une fréquence constante et une amplitude réglable par un premier régulateur de l'amplitude; c) un deuxième raccordement de sortie (A2); d) un deuxième oscillateur (OSZ2) qui applique une deuxième tension alternative au deuxième raccordement de sortie (A2), cette deuxième tension alternative ayant la même fréquence que la première tension alternative et une amplitude réglable par un deuxième régulateur de l'amplitude, mais une phase décalée de 180° par rapport à la première tension alternative; e) un raccordement d'entrée (E) pour introduire un signal d'entrée; f) un redresseur (PG) à commande de phase relié au raccordement d'entrée afin de redresser la partie de tension alternative du signal d'entrée; g) un comparateur (AG) relié au redresseur qui reçoit le signal de sortie de ce dernier comme signal de valeur réelle et qui compare ce signal avec un signal de valeur prescrite afin de former un signal de déviation; et h) un intégrateur (I) relié au comparateur afin d'intégrer le signal de déviation et qui transmet le signal intégré en tant que signal de régulation de l'amplitude aux régulateurs de l'amplitude des deux oscillateurs, de sorte que l'amplitude de la tension dans un raccordement de sortie s'élève exactement dans la même proportion que l'amplitude de la tension dans l'autre raccordement de sortie diminue, la somme des amplitudes restant par conséquent constante. Ce circuit d'évaluation permet de raccorder directement un capteur de position d'un étrangleur différentiel sans réseau de résistances et sans source de tension continue. On obtient un signal de mesure sans ondulations qui se modifie proportionnellement au déplacement de régulation d'une tige de régulation (VS) du capteur (DDWG),
Patent EP-0527897-A1 (EP)
Title: Multi-hull sailing vessel.
Inventor: TOLLET DANIEL
IPC: B63B1/10
Filed: 1991-05-03
Abstract: A multi-hulled boat has at least three hulls, with the outside hulls extending forward beyond the central or inside hull or hulls. The hulls are tapered with a cross-sectional configuration that increases in side front to rear, thus forming a channel or tunnel between adjacent hulls which decreases in cross-sectional size front to rear. Air entering the tunnels is compressed, thus imparting a lifting force to the hulls lifting the hulls partially out of the water to decrease the hydraulic drag on the hulls. The hulls have identical cross-sectional areas at identical transverse planar sections thereof. The bottom of each hull is flat and inclined at an angle with the horizontal. The hull bottoms join the hull sides at a chamfer which increases in size front to rear. Shutters or flaps may be used to partially or fully close off the tunnels between the hulls to control airflow or to trap water-borne material to be collected and recycled.

IPC: A61N1/365
Filed: 1992-07-29
Abstract: In an implantable medical device (1) for stimulating a heart (2), an activity signal from an activity sensor (7) is transformed by response amplification into a stimulation rate at which a stimulation pulse generator (3) delivers stimulating pulses to the heart (2). Response amplification is automatically optimized because the device (1) contains an evaluation device (14) which over a period of time registers the stimulation rate and then compares this rate to a preset mean rate, whereupon a control device (6) in the device (1) changes response amplification so response amplification is increased when the registered stimulation rate is slower than the mean rate and decreased when the registered stimulation rate is faster than the mean rate.

Abstract: A barrier material for protecting construction materials and the like from fire comprises a composite having at least two layers applied to a substrate to be protected such as gypsum board. An inner layer of the composite, adjacent to the substrate to be protected, comprises an inorganic intumescent material. An outer layer comprises an inorganic composition fusible at a temperature of about 700°F or higher. The outer layer, when subjected to its fusion temperature provides a flexible continuous high temperature protective barrier between the intumescent composition of the inner layer and a fire. The fused surface of the outer layer accommodates the intumescent expansion of the underlying layer(s). 
     The outer layer may comprise an alkali silicate which has intumescent properties at lower temperatures, but which provides an expandable fused vapor barrier for the intumescent expansion of the inner layer at higher temperatures. The inner layer intumescent material may also be an alkali metal silicate but is more preferably a borate compound.

Abstract: A radio alarm system is described which consists of a central station (1) with a receiving unit (2), a computer unit (3) and a transmitting unit (8) and of at least one detector (4) with a transmitting unit (7), computer unit (6), a signalling unit (5) and a receiving unit (12). The receiving units of the central station and of the detector are tuned to the respective transmitting units. In the case of an event, the transmitting unit (7) of the detector (4) outputs a first radio signal to the central station which is received by its receiving unit (2) and in the latter initiates, in a manner for generating a request signal for repeating the first radio signal from the detector (4), that a random-number generator generates a code which is stored in the memory of the computer unit (3) and is used for processing the radio signal which is radiated by the central station. The radio signal is received by the detector (4), forwarded to its computer unit which prepares the repeated signal using the code also received from the central station (1) and which is then radiated by the transmitting unit (7). The receiving unit (2) of the central station (1) receives the repeated signal and forwards it to its computer unit (3) in which the received code is filtered out and compared with the code stored in its memory. If the received code deviates from the stored code, a fault alarm is generated by the central station whereas when both codes are identical, the signal is processed in accordance with its content and the state of the central station. <IMAGE>

Abstract: A system for unlocking any of several vehicles (10) by a passive electronic key (14) coupled to base units (12) in the vehicles (10) by a radio link uses short range LF transmission for signals to the key (14) and VHF transmission for signals to the base units (12). The key (14) has a ferrite antenna (38) connected to a receiver (36) comprising a comparator. When an operator pulls the door handle, codes stored in the base unit (12) are transmitted to identify any authorized key (14) within the range. The key (14) has a memory (50) partitioned into separate blocks for different base units (12) and another block for a scratchpad memory. A state machine (44) stores the block addresses and controls access to the blocks (50) according to the transmitted codes. When a block is accessed, a secure ID in the block is sent to the base unit (12) to verify that the key (14) is authorized to unlock the vehicle (10). The ID can be updated upon command from the base unit (12) using the same codes to assure that an authorized unit is receiving the new ID. The new ID is written to the scratchpad, verified for correctness, and the scratchpad address is exchanged for the address of the block containing the old ID. Auxiliary data specific to the vehicle (10) or to the user of the electronic key (14) may also be stored in the memory blocks (50) and retrieved along with the ID.
