Abstract: High-pressure fans, particularly those for gas heating appliances, should create little noise, have a steep pressure-volume flow curve and be capable of construction in compact form. In the case of radial fans with cylindrical rotors the requirements for low noise and compact construction are mutually exclusive. A fan is proposed having such blade duct cross sections that the flowing medium, for example air or an air-gas mixture, is drawn in axially, accelerated radially and expelled axially. For improved utilisation of the kinetic energy a baffle device or a reversed diagonal wheel or a combination of baffle device and reserved diagonal wheel is post-connected to the fan wheel. <IMAGE>

Abstract: To determine whether a measurement gas is a rich-burned exhaust gas or a lean-burned exhaust gas, an oxygen concentration sensor is used which has a pumping cell (40) with a solid electrolyte member (34) of an oxygen-ion conductive material and two electrodes (36,38) of which a first one is exposed directly to the measurement gas and the second is exposed thereto through diffusion-resistance means (34), and a sensing cell (30) with a solid electrolyte member (24) conducting oxygen ions and reference electrode (28) and a measurement electrode (26) which is exposed to the same atmosphere as said second electrode (38) of the pumping cell. An electric current is applied to the electrode (38) exposed to the measurement gas through the diffusion-resistance means, such that the electric current flows in one of opposite directions depending upon whether the measurement gas is the rich-burned exhaust gas or the lean-burned exhaust gas, so as to keep stoichiometric an atmosphere adjacent to that electrode (38). Change in the direction of flow of the electric current, or change in polarity of the voltage which provides the electric current is detected.

Abstract: A high flux membrane module comprises two membrane leaves (12) (see Fig. 1) wrapped about a central permeate flow tube to define a flow path for permeate in the membrane leaves (12). The membrane leaves (12) contain two or more separate permeate flow compartments (26, 28) within each membrane leaf to provide for the separate permeate flow of the permeate within the compartments (26, 28) to the permeate outlet. This reduces the area (30, 32) of the permeate back pressure compared with as seen at (22) in the prior art of Fig. 1, thus reducing membrane wrinkling and membrane failure particularly during membrane cleaning cycles.

Abstract: Un système d'affichage plat en couleurs comprend un dispositif plat d'affichage en couleurs et un dispositif de commande dudit dispositif d'affichage. Le dispositif de commande comprend trois registres analogiques à décalage pour l'enregistrement des signaux analogiques d'images correspondant aux trois couleurs primaires. Les signaux analogiques sont lus dans ces registres selon un procédé ligne par ligne. L'avantage de l'utilisation d'un dispositif analogique d'enregistrement (13, 14, 15) au lieu d'un dispositif numérique consiste dans le fait que seul un convertisseur N/A (21) est nécessaire et que les signaux peuvent être aisément lus en parallèle. Selon un procédé spécial de commande, seul un tiers des électrodes des segments reçoit les signaux d'image. Un potentiel de blocage est appliqué aux autres segments situés entre les segments actifs qui reçoivent les signaux de couleurs.

Abstract: A by-pass valve for a boring column comprises a hollow casing (1) with lateral openings (2), a saddle (4) constituted by the internal surface of the casing (1) and a closing element consisting of an elastic, resilient sleeve (3) secured by one of its ends in the casing (1). The sleeve (3) is mounted with a gap (6) and is provided with a confusor (7). The valve may be provided with a jacket (8) or with shutters. The absence of moving parts, better sealing of the channel for the flow of the liquid, and decreased hydraulic resistance of the valve lead to a reduced wear and destruction of its parts and increases the reliability and longevity of the valve.

Title: Laser harmonic generation employing low-loss external optical resonator.
Inventor: KOZLOVSKY WILLIAM J
IPC: G02F1/35
Filed: 1989-06-21
Abstract: TEMOOq laser radiation derived from a diode-pumped ring laser is directed into a faceted member of nonlinear optical material defining either a standing wave or ring monolithic optical resonator to generate harmonic laser radiation. The losses of the optical resonator, exclusive of the conversion loss to the harmonic, are made sufficiently low such that the dominant loss presented to the resonated mode of the optical resonator is the conversion loss to the generated harmonic. The reflectance of the input mirror of the optical resonator is impedance matched to the losses of the resonator including the harmonic conversion loss for optimum conversion efficiency. The length of the nonlinear optical material is shortened to the point where the bulk losses are less than ten times the sum of the surface and mirror losses, yielding conversion efficiencies of greater than 20 percent.
