Patent FR-2327603-A1 (FR)
Title: Electro:optical viewing and photographic recording system - has modulator with shift registers to store data for display
Inventor: GAUTIER CHRISTIAN JEAN
IPC: H04N1/405
Filed: 1975-10-06
Abstract: The electro-optical viewing and photographic recording system has an electro-optical transducer which enables one to view numerical signals. Each numerical word corresponds to a point on the viewing screen including binary elements or different weight bits. The modulator has as many shift registers as there are points to be simultaneously displayed. Each register has as many cells as there are bits in a numerical word, plus an output cell. The output cell is read by a shift signal supplied from a timer which delivers pulses whose mutual spacings are a function of the weight of the bit of the word to be shifted in the output cell. The output signal of the cell is applied, directly or indirectly, to actuate the electro-optical transducer from the point associated with a word at constant level when the shifted bit in the output cell is 1 and to a null level when the bit is 0.

Title: Integral cast turbine runner wheel - is produced in rotating mould by pouring different materials for blades and for disc
IPC: F01D5/34
Filed: 1976-02-26
Abstract: A composite cast turbine runner wheel consisting of a disc with integral blades is produced in a rotating mould with a coaxial pouring gate. For the blade region, a material with a high heat resistance is poured first in the gate, followed by another material for the disc which has high strength at low temperatures. This saves the expensive heat-resistant material for the disc (where it is not needed) resulting in lower production costs. The wheel meets all mechanical and thermal requirements in the most rational way.

Title: Modular mouth organ with special reed assembly - employs varying sequence to play predetermined tune in one sweep along reeds
IPC: G10D9/00
Filed: 1976-03-19
Abstract: The musical instrument, consists of a number of materially different elements each containing a frequency generator, which can be joined together in various ways to form a curved structure. By varying the sequence in which the elements are connected, different melodies may be built up, which may be played by activating the elements in succession. The frequency generators may be in the form of reeds activated by blowing or sucking in the style of a mouth organ. Each element is in the form of a prism, and has a symbolic character on the outside to indicate the note concerned.

Title: Fixing clamp for ceramic gas filled insulator - has shaped alloy pad in clamp with annular sealing rings to accommodate surface irregularities
IPC: H01B17/26
Filed: 1976-04-22
Abstract: Fixing clamp holding cylindrical ceramic insulators against a flat surface such that a gas tight seal is achieved where the interior of the insulator is filled with a gas such as sulphur hexafluroene. The clamp takes up tolerance varations in the insulator surface minimising the possibility of damage to the ceramic. The insulator (10) is held against its base by a ring of separate clamps (16) bearing against alloy pads (22) and through them onto a shoulder on the insulator. Each pad has a convex surface whose radius is slightly less than that of the bearing surface. Insulator base irregulatories are taken up by a pair of annular sealing rings trapped within slots in the base.

Title: Spray coating glass with metal oxide - using metal acetylacetonate powder and preheating the glass
Inventor: FUJIWARA KENJI
IPC: C03C17/23
Filed: 1976-06-24
Abstract: A thin film of metal oxide is formed adherent to a vitreous (glass) surface by projecting a fine powder of a metallic cpd. such as an acetyl acetonate thermally decomposable into the oxide. The powder is sprayed onto the glass which has been preheated to a temp. below the softening point of the glasS, but high enough to bring its resistivity to 1010 ohm-cms. A high potential difference is then applied between the glass and the spray appts. to give the powder an electric charge. Process is used for coating a glass, glass ceramic or refractory support, e.g. for a sunlight attenuating window or one with a electrically conducting surface. Process provides improved optical and electrical properties. It avoids the cooling effect on the glass surface obtained when a soln. of the metal cpd. is sprayed onto the surface, and the loss of heat energy used to evaporate the solvent. The coating adheres more strongly due to the slower cooling. It also avoids the problems of fire risk and air pollution when using org. solvents.

Title: Multideck baking oven control - has alternate heat input to groups of oven decks to reduce installed rating (NL 24.1.78)
IPC: A21B3/04
Filed: 1976-07-22
Abstract: In a heating system for multi-deck baking ones which are ehated by heating elements, heat exchangers or steam generators, the oven decks are subdivided into gps. which receive a heat input in turn. The maximum input of a gp. is chosen to equal the installed rating of the oven. The new system requires less extensive alterations to the mains or heat supply when a new baking oven is installed. If divided into two gps. only 50% of the installed rating of a conventional oven is required.

Title: Inflatable dinghy comprising thermoplastic sectors - with curved weld seams at sector edges extending around inflated tube
IPC: B63B7/08
Filed: 1976-09-22
Abstract: Mfr. of an inflatable dinghy is carried out by placing sealable thermoplastic webs each of which forms a sector in the flat state one on top of the other, and joining them together in an edge zone along a curved weld seam, which is the flattened form of the weld seam which subsequently extends around the inflated tube. All the connected sectors are then bent around the longitudinal axis of the tube, and closed by welding in the common flat overlapping edge. Pref. the thermoplastic material comprises a sheet-like or fabric-like PVC. The length and width of each web is pref. greater than the width and circumference of the sector by the amt. required for the weld seam. The method can be carried out without shaping tools and in a shorter time than previously.

Title: Roasted iron ore pellets with controlled macroporosity - which raises softening point and improves degree of redn. obtd.
Inventor: FUJITA ISAO
IPC: C22B1/16
Filed: 1977-03-02
Abstract: Roasted iron ore pellets which are porous contain macropores of 0.1-3.0 mm. dia. The macropores constitute max. 25% of the total porosity, pref. 5-25%, and esp. 15-25% of the total porosity. The raw material used for the pellets pref. contain by wt. up to 3% MgO as a flux. Pref. the raw materials are crushed and contain max. 4% carbonaceous material, size 0.1-3 mm. dia., with max. 3% MgO, 0.1-3 mm. dia. The mixt. is then pelletised and roasted, so that max. 25% of the pores are macropores with dia. 0.1-3 mm. Used for mfr. of pellets used in a blast furnace to make crude iron. The intentional macroporosity results in a consistently high and uniform degree of redn. because the redn. gas can penetrate the macropores. The pellets also have a high m. pt. so they flow smoothly down the blast furnace without sticking; and the macropores facilitate the redn. of dusts obtd. in purifying waste gases to avoid environmental pollution.

L'invention s'applique notamment à des récepteurs portatifs de radiophonie et de télévision.
Patent FR-2393286-A1 (FR)
Inventor: ORTLINGHAUS ULRICH
IPC: G01K17/16
Filed: 1977-06-08
Abstract: This measures the quantity of heat dissipated by a fluid to a heat exchanger. It has a flow meter, one heat sensor each in the feed and return sides of the water circulation in the heat exchanger, a saw-tooth voltage generator (40), comparators (32, 33), and a counting clock generator (50). The heat sensors, which are constructed as linear measuring shunts (5, 9), are fed respectively from a constant-current source (17, 23), it being possible to switch the inputs (30, 31) of the comparators (32, 33) jointly to calibration resistors (22, 28). A logic element is driven in accordance with the difference between the voltages transmitted by the heat sensors and the saw-tooth voltage. In one circuit state of the logic element, the voltage pulses of the counting clock generator (50) are fed for display to a counting mechanism (47), the constancy of the currents through the heat sensors being guaranteed for the duration of a measurement period by being automatically calibrated at adjustable intervals by means of a control loop (50, 52, 55, 58). This device renders it possible to determine precisely a quantity of heat dissipated, e.g. in district heating, or a quantity of heat absorbed by a consumer.
