Abstract: A method and apparatus are disclosed for monitoring a fluid stream with reference to one or more criteria. Successively a number of samples is drawn from the fluid stream that is at least one more than the number of analysis criteria. Each sampling step includes analyzing a portion of the fluid stream and preserving another portion. At intervals, on the ground of a selection criterion, one of the samples preserved is removed and a fresh sample is drawn, whereby - again - a portion of the fluid stream is analyzed and another portion preserved. The arrangement is such that, at all times, one sample is preserved that corresponds with an extreme value of each of the criteria of analysis.

Filed: 1988-09-05
Abstract: A signal voltage applied between the input terminals (3, 4) is converted by means of a differential amplifier (T₇-T₁₀) into two phase-opposed signal currents which are inverted by means of a differential-to-single-­ended converter (10) into a single-ended signal current. The converter (10) comprises a first and a second transistor (T₁, T₂) with a common gate electrode and a third and a fourth transistor (T₃,T₄) also with a common gate electrode, whilst the drain electrode of the third transistor (T₃) is connected to the common gate electrode of the first and the second transistor (T₁, T₂). The common gate electrode of the third and the fourth transistor (T₃, T₄) is main­tained at a voltage which is equal to the sum of one threshold voltage and two saturation voltages by means of a fifth transistor (T₅) whose gate electrode is connected to the drain electrode and to a bias current source (I₂). The output (5) of the amplifier can be driven by means of this converter (10) up to two saturation voltages of the negative supply terminal (1).

Patent EP-0300683-A1 (EP)
Title: Marine propeller
Inventor: VORUS WILLIAM STERLING
IPC: B63H5/07
Filed: 1988-07-13
Abstract: A multi-bladed marine propeller designed for efficient operation in intermediate, partially cavitating flow regions between fully cavitating flow and noncavitating flow. Each of the blades (10; 62; 104) has a radially inner subcavitating section (18; 64; 108) and an outer section (28; 66; 110) which is configured to have a higher angle of attack and tapered trailing and leading edges so that it supercavitates at high speeds either with or without ventilation and subcavitates at low speeds. Various other features of each blade include different length chords on the pressure and suction sides of the outer section and an inclined trailing surface area (80; 118) extending between the chord ends for improved off design, design point, and astern operation. A minimised transition area (48; 74; 112) is included between the inner and outer sections, and narrow chord lengths are provided in the tip area to minimise and balance overall tip section drag. The supercavitating outer section also has positive rake to improve ventilation performance and positive skew to minimise undesirable transition flow. The result is a propeller with improved efficiency at low speeds without degrading the supercavitating section performance at high speed.

Title: Procede de stockage de donnees optiques et materiaux destines a cet usage
Inventor: WALLACE STEPHEN CHARLES
IPC: G11B7/24035
Filed: 1988-05-27
Abstract: Un procédé servant à stocker des données optiques utilise un matériau de changement de dispersion photo-induit (PIDC), tel qu'un fulgide photochrome, qui peut se transformer de façon réversible par absorption d'un rayonnement à une longueur d'ondes lambdaw et prendre une forme modifiée thermiquement stable ayant un indice de réfraction différent. Les opérations d'écriture sont effectuées à une longueur d'ondes lambdaw, ce qui permet de transformer le matériau PIDC dans des régions localisées pour qu'il prenne la forme modifiée, produisant ainsi une différence de l'indice de réfraction deltan entre chaque région et le matériau PIDC immédiatement adjacent. Les opérations de lecture sont effectuées à une longueur d'ondes lambdar le long d'un chemin de longueur L sur un matériau PIDC, deltan et L étant choisis de sorte qu'il y ait une différence de phase de nlambdar/2 entre le rayonnement traversant une région et le matériau PIDC immédiatement adjacent à cette région. Les opérations d'écriture, de lecture et d'effacement peuvent être effectuées à partir de l'un ou des deux côtés du matériau PIDC qui est placé de façon adéquate sur un substrat en forme de disque.

Abstract: A washing device for parts of human body comprises a thermostat mixing valve (T) which is disposed at a junction of a cold-water supply passage (2) and a heated-water supply passage (1), a latching solenoid valve (V₁) which is mounted on a heated-water drainage passage (6) branched out from said heated-water supply passage (1) and a latching solenoid valve (V₂) which is mounted on a mixed-hot-water supply passage (m). Due to such construction, electric power for heating water is no more necessary in the toilet bowl (B) and electric power for mixing heated water and cold water to produce mixed hot water to be ejected from an ejecting nozzle (7) also becomes unnecessary. Furthermore, electric power for operating the solenoid valve (V₁, V₂) is minimized by means of a latching solenoid. Accordingly, the overall consumption of electric power necessary for operating and controlling the washing device can be minimized thus enabling the use of a small dry (D) cell or battery as an electric power source of the washing device.
