Patent EP-0248719-A1 (EP)
Inventor: SIRETCHI ROMAN RESIDENCE LES J
IPC: A61M5/14
Filed: 1987-05-29
Abstract: First and second spaced apart optical emitter-receiving pairs are located along a liquid carrying conduit. A regulator circuit is coupled to each emitter-receiver pair to control the operation of that pair inside a maximum response range regardless of the transparency of the liquid. The regulator circuit is so arranged as to supply the emitter with a voltage which is a function of the difference between a voltage supplied by the receiver portion of an optical-receiver pair and a reference voltage. A differential circuit produces a differential signal representing the difference between the signals produced by the receiver portions of the optical emitter-receiver pairs and a comparator circuit is connected to the differential circuit in order to generate an alarm signal as a function of the differential signal. The detector is particularly useful as an air bubble detector in a transfusion or perfusion system, and can also provide a container-empty alarm in such systems.

Title: Hypobaric storage of respiring plant matter without supplementary humidification
Inventor: BURG STANLEY R
IPC: A23K3/02
Filed: 1987-08-10
Abstract: The hypobaric preservation of respiring plant matter without the step of humidifying the storage atmosphere by con­
tacting it with a supplementary body of heated water is hereby disclosed, characterized by storage at controlled and corre­
lated conditions of temperatures, subatmospheric pressure, evacuation rate, air recirculation rate and air intake rate, and 
by the dependence of each set of correlated conditions upon the weight, respiration rate and type of plant matter. Ex­
panded relatively dry atmospheric air is passed into and humid rarified air is withdrawn from the storage chamber (16) at 
rates which maintain an optimal steady-state oxygen partial pressure for each type of respiring, oxygen-consuming plant 
matter (15), and a nearly saturated relative humidity sufficient to keep the temperature of the respiring, heat producing 
plant matter (15) equal to or slightly higher than the temperature of the chamber walls (16) and rarified air.

Abstract: As an optical spot (20) is scanned along a recording track (B) it interacts with optical markers (14,16) disposed at regular intervals along adjacent sides of the track. Each interaction with an optical marker causes a peak value which is sampled and held (74, 76). A clock (46) drives a clock signal from the regular periodicity of the optical markers. A logic circuit (48) controls the sample and hold circuits such that the peak amplitude attributable to each optical marker is temporarily held. An adder (52) combines peak values attributable to optical markers on opposite sides of the track to produce a threshold signal (100) indicative of a sum or average thereof. A comparator (58) compares data (56) read from the track with the threshold signal. The comparator indicates a "1" level in response to the data signal exceeding a threshold and a "0" level in response to the data signal being below the threshold level. A decoder (60) is clocked by the clock pulses to convert the 1 and 0 indications into a binary pulse train. In this manner, the threshold level which distinguishes between 1's and 0's varies or floats in accordance with the relative interaction of the optical beam and the optical markers on one or the other side of the track, i.e. the misalignment of the optical beam and the track. The threshold signal also varies in accordance with variations in the recording medium.

Abstract: A transducer for hydrophones is proposed which consists of a layered structure (10) of supporting layers (11) and a piezoelectric layer (15), and in which the piezoelectric layer (15) is arranged between the supporting layers (11) essentially in the neutral plane (18) of the layered structure. As a result, bending loads do not produce force components whose directions of action lie in the plane of the piezoelectric layer, so that interference voltages generated piezoelectrically by such forces are avoided. Such transducers are preferably applied in  hydrophones in towed or longitudinal antennas of watercraft. <IMAGE>

Abstract: A method and apparatus for implementing a thermo­dynamic cycle, which includes the use of a composite stream, having a higher content of a high-boiling component than a working stream, to provide heat needed to evaporate the working stream. After being superheated, the working stream is expanded in a turbine (102). Thereafter, the expanded stream is separated (131) into a spent stream and a withdrawal stream. The withdrawal stream is combined (141) with a lean stream to produce a composite stream. The composite stream evaporates the working stream and preheats the working stream and the lean stream. The composite stream is then expanded to a reduced pressure. A first portion of this composite stream is fed into a gravity separator (120). The liquid stream flowing from the gravity separator (120) forms a portion of the lean stream that is combined with the withdrawal stream. The vapor stream flowing from the separator combines with a second portion of the composite stream in a scrubber (125). The vapor stream from the scrubber (125) combines with a third portion of the expanded composite stream to produce a pre-condensed working stream that is condensed forming a liquid working stream. The liquid streams from the scrubber (125) and gravity separator (120) combine to form the lean stream. The liquid working stream is preheated and evaporated transforming it into the gaseous working stream. The cycle is complete when the gaseous working stream is again superheated.

Abstract: Sont décrits un procédé et un dispositif pour réguler la quantité d'injection de carburant au moyen d'une pompe d'injection de carburant. Ce procédé et ce dispositif permettent de réduire le bruit d'un moteur diesel pendant le ralenti et en charge partielle. La pompe d'injection de carburant comprend au moins un piston (3) produisant la pression nécessaire à l'injection et délimitant une chambre de travail (5) dans la pompe, ainsi qu'une soupape (26) qui s'ouvre par la pression de l'élément dans la chambre de travail (5) et se ferme au moyen d'un dispositif électromagnétique (34, 37). Lorsque la soupape (26) est ouverte, une partie du carburant refoulé dans la chambre de travail de la pompe (5) est évacuée par l'intermédiaire d'un canal de décharge (29) sans être injecté. La quantité de carburant parvenant à l'injection par unité de temps étant réduite, il faut allonger la durée globale de refoulement. L'allongement de la durée de l'injection permet une diminution du bruit de combustion. Lors de la charge partielle du moteur, la soupape (26) est fermée au moyen d'un dispositif électromagnétique(34, 37) après écoulement, depuis l'ouverture de la soupape, d'un intervalle de temps (DELTAt). Le carburant encore refoulé par la suite parvient pleinement à l'injection. L'ordre de grandeur de l'intervalle de temps (DELTAt) entre l'ouverture et la fermeture de la soupape est déterminé dans une unité de commande électronique (52) en fonction des paramètres de charge (59, 62) du moteur. Pendant la pleine charge du moteur, la soupape (26) reste fermée.

Abstract: When subdividing cast billets, the flame-cutting machines used for this are clamped via clamping jaws (17) tangentially against the longitudinal edge of the billet (19).
