Patent EP-0446324-A1 (EP)
Title: Backlighting apparatus.
Inventor: BOND DAVID L
IPC: G09F13/18
Filed: 1990-08-22
Abstract: Improved backlighting apparatus evenly illuminates positive and negative LCDs under all ambient lighting conditions. Incandescent lamps (301-304) provide light for distribution by a light pipe (101). The bottom of the light pipe (101) is selectively painted white to reflect light to the top of the light pipe (101) while the unpainted areas reflect light internal to the light pipe (101), controlling hot and dim spots. The corners of the light pipe (101) near the lamps (301-304) are dual angled to reflect the light into the center of the display. The burn-out of a lamp (301-304) will not substantially affect the even lighting capabilities of the apparatus.

Abstract: A high definition camera for photographing still pictures using a high resolution charge-coupled solid-state imaging device. The camera includes an electronic view finder (17) in which an image is reproduced by reading pixel signals from the imaging device. The image is formed with high resolution responsive to high resolution television systems. Plural memory areas (4 to 7) are used to store the pixel signals and an image is reproduced based on pixel signals read from designated memory areas while further pixel signals are simultaneously being stored in memory areas other than the designated ones. In a further embodiment, pixel signals are read by every frame region wherein a horizontal charge transfer path of the imaging device includes a pair of charge transfer lines. Low frequency video signals can be supplied to the electronic view finder even in the event that the number of pixels are increased.

Abstract: The recovery of rhodium, present as a homogeneous dissolved complex compound especially in residues of products of the oxo process, is carried out in a two-stage process. In the first stage, the residues are treated with a gas-containing oxygen in the presence of a C2- to C4- monocarboxylic acid and an alkali metal salt of a C2- to C4-monocarboxylic acid, and are then extracted with water. In the second reaction stage, they are treated again with a gas-containing oxygen, an aldehyde, a C2- to C4-monocarboxylic acid, and an alkali metal salt of a C2 to C4 monocarboxylic acid, and are extracted once more with water.

Abstract: The invention relates to a device and method for determining the time of occurrence of a sampling time (t  n ) in a time period that extends from a first measurement time (t a ) to a second measurement time (t  b ). The number of cycles (X n ) of a clock signal (CLK) is counted between t n  and t b  and the number of cycles(Y n  ) of the clock signal (CLK) is counted between t  a  and t b . 
     The count signals (X n ) and (Y n ) are corrected to (X  nc ) and (Y  nc ) in response to phase signals (a n  ) and (b n ) representing the phase of the clock signal (CLK) at measurement times (t a  ) and (t  b ) respectively; and the sampling time (t n ) is measured relative to the measurement time (t a ) by determining the quotient (X nc /Y nc ).

Abstract: The non-destructive testing of materials, particularly coarse grain materials such as the carbonaceous materials used in the anodes and cathodes of an aluminium smelting furnace, using longitudinal compression waves employs a waveguide (26, 28) to apply the waves to a specimen (10), the specimen having a cross-sectional dimension Dg of between 3 and 5 times the material average grain size Dg. Alternatively, or in addition, the waves used preferably are of effective wavelength from about 30Ds to 50Ds. Alternatively, or in addition, the effective wavelength of the waves is preferred to be approximately equal to the length of the sample; the necessary very long samples may be obtained by connecting a plurality of smaller elementary samples end-to-end. The apparatus may include a controllable furnace (12) for cycling the sample (10) to determine the change with temperature of the physical characteristic that is being measured. The methods and apparatus employ relatively low frequencies, in the sonic range, and high powers; although particularly suited for measurements with coarse grain materials they are also very effective with more usual fine grain materials, such as ceramics.

Abstract: Le porte-buse comprend un conduit de liquide et une valve (5) actionnée par un bouton de commande (8) qui, en position de repos, laisse libre le passage du jet de liquide pulsé vers la buse fixée sur le porte-buse et qui, en position pressée, ferme ce passage. La valve (5) comprend une chambre (9) en communication avec la partie amont (6) du conduit et reliée à travers l'ouverture (7a) de la valve à la partie aval (7) dudit conduit. Cette chambre (9) est limitée partiellement par une coupelle (10) élastique déformable par le bouton (8) et qui, à l'état de repos du bouton (8), sous l'effet de sa propre élasticité et de la pression du liquide, reste écartée de l'ouverture (7a) de la valve et est totalement inactive, tandis que, sous l'action du bouton pressé, elle couvre l'ouverture (7a) de la valve (5) pour bloquer le passage du liquide. Dans cet état de blocage, la partie de la coupelle (10) entourant l'ouverture (7a) de la valve est déformable sous l'effet des pulsations du liquide tel que ladite chambre subit une expansion périodique amortissant ces pulsations de liquide. <IMAGE>

Abstract: Les soupapes de compensation de pression disposées en aval des distributeurs directionnels sont utiles pour le fonctionnement de systèmes hydrauliques de régulation d'écoulement proportionnels et servent en général de contrôles de charge. La soupape de compensation de pression et de contrôle de charge (32, 33) de la présente invention est conçue pour être utilisée avec un système hydraulique commun dans lequel la pression d'un signal de pression commun dirigé vers toutes les soupapes de compensation de pression du système est limitée à un niveau maximum prédéterminé. La soupape de compensation de pression comprend un élément de soupape (56, 58) disposé en aval d'un orifice doseur (54, 55), un piston de charge séparé (74, 75) disposé bout à bout avec un élément de soupape dans un trou commun (46, 47), et un ressort de compensation de pression (84, 85) qui est disposé dans une chambre (82, 83) derrière le piston de charge et qui sollicite le piston de charge et l'élément de soupape jusqu'à la position de contrôle de charge. Le signal de pression de charge commun est transmis à la chambre contenant le ressort, tandis que la pression de charge effective d'un moteur hydraulique associé est dirigée dans une chambre (78, 79) située entre l'élément de soupape et le piston de charge de sorte que l'élément de soupape est maintenu dans la position de contrôle de charge par la pression de charge effective quand cette dernière est supérieure à la pression de refoulement de la pompe.
