Patent EP-0284480-A1 (EP)
Inventor: GAY MICHEL
IPC: G09G3/28
Filed: 1988-03-08
Abstract: This panel comprises a plurality of elementary image points (P1, P2, P3, P4). Each point consists of several zones (Z1, Z2, Z3) covered with luminophores of various colours. Each of these zones corresponds to the crossing of electrodes allowing, during operation, control signals, and in particular a servicing signal, to be applied to each zone covered with a luminophore. The method according to the invention consists in applying to the zones covered with a luminophore of a particular colour, a particular servicing signal with adjustable frequency, differing from one type of luminophore to the next (fR, fG, fB). The adjusting of the colours of the panel is done by modifying the frequency of the various servicing signals thus used. 
<??>Application to polychrome plasma panels, be they of alternating or direct type with memory.

Title: Procédé de fabrication de lentille de contact en un polymère protéique naturel par moulage avant réticulation
Inventor: BOURSET CLAUDE
IPC: B29D11/00
Filed: 1988-06-17
Abstract: Le procédé de fabrication de lentille de contact part, de façon connue d'un polymère protéique biologique, du type gélatine ou un collagène humain enrichi en type IV; on constitue un hydrogel en faisant gonfler le polymère dans l'eau ou un sérum physiologique. On constitue des préformes, à une température intermédiaire entre l'ambiante et la température de liquéfaction de l'hydrogel, l'hydrogel étant pâteux. La préforme, qui reproduit avec plus ou moins de précision la forme de lentille finie, avec toutefois un excès de matière, est placée dans un moule en matériau diélectrique à faibles pertes en au moins deux parties et apte à définir, après verrouillage récipropre de ses parties, la forme et l'état de surface de la lentille finie. Le moule est soumis à un champ électromagnétique à 2,45 GHz en sorte que l'hydrogel soit porté à température de liquéfaction. Le moule est alors verrouillé et refroidi jusque vers 4°C. La lentille est alors démoulée, puis réticulée par contact avec un agent réticulant tel qu'un aldéhyde. Les lentilles obtenues sont de forme et d'état de surface excellents, et très bien tolérées biologiquement.

Abstract: Procédé de préparation de D-alanine, consistant à cultiver une levure particulière appartenant à l'un quelconque des genres Candida, Saccharomycopsis, Pichia, Torulopsis, Cryptococcus, Hansenula ou Trichosporon, pouvant digérer la L-alanine et ne digérant essentiellement pas la D-alanine dans des conditions acides, en utilisant un milieu contenant de la DL-alanine en tant que source essentiellement unique de carbone et d'azote. Ce procédé permet d'alimenter le milieu en DL-alanine fortement concentrée, et d'obtenir de grandes quantités de D-alanine rapidement et avec un bon rendement. A la fin de la culture, le milieu ne contient pratiquement pas d'autres sous-produits organiques ni d'impuretés organiques, ce qui facilite l'isolation et la purification de la D-alanine.

Abstract: A heat exchanger apparatus (10) for electrical 
components (12) submerged in a dielectric liquid (14) 
includes a closed main chamber (16) for holding the li­
quid and a non-condensible gas above the liquid. A 
closed blockage chamber (22) is positioned within the 
main chamber in contact with the dielectric. The block­
age chamber holds non-condensible gas and segregates 
the gas and vapors of the liquid formed during opera­
tion of the heat exchanger. The side walls of the cham­
bers are spaced from each other to form a narrow con­
densation and segregating duct (24) within which the 
vapors of the liquid rise and condense. An orifice (26) 
is provided in the closed blockage chamber near the 
top thereof. The orifice is sized to allow entry into the 
blockage chamber of the non-condensible gas as the 
gas is swept up the duct but to inhibit entry of the li­
quid should the apparatus be inverted or experience 
zero gravity forces.

Title: Liquid flow control device
Inventor: MILES PETER
IPC: G05D11/00
Filed: 1988-10-10
Abstract: A liquid flow control device (20) comprises a variable orifice (28/30) in a 
conduit (15), and branch lines (41, 42) above and below a flow restriction, 
which may be the variable orifice itself. The orifice is controlled to maintain a 
predetermined relation between the pressures (P₁, P₂) in the two branches. A 
metering valve (60) for a second liquid to be injected into the conduit may be 
controlled simultaneously to maintain a preset ratio between the flow coeffi­
cients of the valve and the orifice, so that if the pressures above and below the 
metering valve are the same as the pressures above and below the variable ori­
fice, the respective flow rates will stay in the same proportion, and the propor­
tion of second liquid injected into the liquid in the conduit will be constant at 
all flow rates. The orifice control may be by piston and cylinder (50, 52) driven 
by the liquid pressures in the branch lines, the moving piston turning an ori­
fice control rod (36) which also rotates a variable plug (62) in the metering 
valve. The specific application is for the injection of foam concentrate into a 
fire water distribution system, especially on an offshore oil platform, where 
flow rates and pressures will vary in use according to the instantaneous de­
mands for water. The metering device is capable of handling water flows be­
tween 100 and 2250 m³/hr. at pressures of around 15 bar while providing an 
output solution within about ±10% of the 1%, 3% or 6% target concentra­
tion over the full range of pressure and flow conditions, with the ability to 
withstand surge pressures as high as 30 bar.

Abstract: In known stationary or semi-suspended rescue baskets, in particular those whose pivot axis is situated outside the axis through the centre of gravity, high displacement forces occur which are necessary for swinging the basket, with respect to the ladder, in the different working positions and in the non-used position. The high displacement forces for the most part require plurality of drive units together with a comparatively high energy requirement. The rescue or work basket (2) comprises, at the least, one rotary bar (5), preferably outside the pivot axis (1) of the rescue basket (2). This means that particularly the drive for displacing the basket can be of small design. <IMAGE>

Abstract: A mass flowmeter for measuring velocity of a flowing fluid employs a thermal sensor (11). The sensor (11) generates heat when supplied with electrical power. A heat sink (25) is located in the fluid flow a selected distance normal to the line of flow of fluid from the sensor. Electrical power is supplied to the sensor (11) to cause a thermal flux to flow from the sensor (11) to the heat sink (25). The flowing fluid modulates this flux. A circuit (23) measures the temperature of the sensor and computes the velocity of the flowing fluid from that measurement.

Title: Process for conversion of biomass
Inventor: SCHMITT MARTIN ERICH
IPC: C05F17/00
Filed: 1989-08-17
Abstract: In a process for conversion of biomass into soil conditioners, manures and/or plant culture substrates, the possibly size-reduced biomass is placed in a heap and allowed to undergo natural decomposition processes until the desired degree of conversion is reached. Various types of biomass are disposed in superimposed layers each consisting mainly of one type of biomass. The lowest layer consists mainly of wood comminuted to sawdust particle size, the next layer consists mainly of green vegetables, the next layer consists mainly of surface-moistened straw, and the next layer consists mainly of manure containing cow manure. A further layer consisting mainly of wood size-comminuted to sawdust particle size is placed over the top. The thickness of the layers of comminuted wood is such that they prevent the escape of the volatile decomposition products.
