Title: Silicon solar cells with high efficiency - obtd. by doping transparent silica layer with stable ions
IPC: H01L31/062
Filed: 1973-05-14
Abstract: A cell with its absorption band in the visible spectrum, comprising a p- or n- doped substrate contg., on the window side, a grid of the opposite type, i.e. n- or p-, and covered with a transparent dielectric.

Title: Powder for crystal prodn by the Verneuil process - obtd. by melting particulate matl. in furnace
IPC: C30B11/10
Filed: 1973-06-05
Abstract: Particulate material is melted in an oxyhydrogen flame in a furnace, producing spheres of =10 mu dia. which are separated from the combustion products.

Title: Staircase construction using two types of elements - by placing precast stairheads for casting of treads, and facings added later
IPC: E04F11/035
Filed: 1975-03-18
Abstract: Staircase construction using two different types of element those which are incorporated into the building itself during its erection, and others which are added later and which form the actual flight of stairs. This type of construction can be used for a variety of buildings, even those where the height between storeys is different and the width of the staircase varies. The first group of elements (1-8) are precast and include the stairhead. They are put in position simultaneously with the central core to which they are linked. It is possible for these elements to be narrower than the actual stairwell allowing for variations in width in different buildings. The second group of elements consists of individual steps and facing panels, forming the actual stairway. These can be positioned at an appropriate stage in the construction process.

Title: Flow blocking valve for aggressive fluids - has valve closure element actuated by toggle levers for hermetic closing
IPC: F16K3/18
Filed: 1975-06-23
Abstract: The flow blocking valve has retractable closing element for sealing channels carrying a fluid. This valve is used especially for controlling flow or dangerous fluids such as, for example, uranium hexafluoride. The sealing efficiency is comparable to the sealing efficiency in vacuum plants. No special production precision is necessary in its making. The valve housing is not deformed in use and this eliminates risk of damage due to friction and flexible sealing components. The actuating mechanism moves the closure unit completely out of the flow path by a lever mechanism with outwards swinging links on both sides of the actuating spindle. The levers (13, 16) are pivoted forming a toggle arrangement which pushes the valve closure plates against the sealing seats.

Patent FR-2319850-A1 (FR)
Title: Gas fired water heater with exhaust gas fan - has temperature controlled damper regulating combustion air flow
IPC: F24H9/20
Filed: 1975-07-28
Abstract: Heater has a heat exchanger (3) above a gas burner (11) in which water is heated by the flue gases. The gases are discharged to atmosphere through a duct (6) which contains an exhaust gas discharge fan (4). Fresh air enters through an annular duct (5) surrounding the discharge duct (6) and flows round the outside of the heat exchanger (3) to the burner (11). A damper (1) in the side of the exhaust duct (6) above the heat exhanger allows part of the intake air to be drawn directly into the exhaust and thus reduce the air supplied to the burner. This damper is moved through linkage (17) by a bimetal strip (9) in the flue gas path. The gas air ratio is thus varied to maintain constant burner efficiency.
Patent FR-2288173-A1 (FR)
Title: Warp knitter pattern changing - has an auxiliary pattern unit to reduce number of pattern chains needed
IPC: D04B27/28

Abstract: An appts. is claimed for pattern changing on a warp knitter, where the movement of the guide bar for the basic change is effected by the pattern components and their pattern levers, with an auxiliary pattern unit and auxiliary pattern lever which incorporates a pivoting ratchet in a holder. One end of the ratchet lies in reach of gripping pads where at least two double-armed pattern levers are positioned, the other end as the lifting mechanism. The design gives a saving in the number of pattern chains, reducing the manufacturing costs of the fabric.
Patent FR-2334066-A1 (FR)
Title: Central heating system using solar radiation energy - has heat pump and thermal store between absorber and radiators, with three flow circuits
IPC: F24J2/04
Filed: 1975-12-04
Abstract: The heavy heat absorbing wall of a building has a glass plate in front of it forming an air gap in which solar radiation is absorbed. Radiators are placed in this space and water is circulated through them through a first circuit which contains a heating coil within a water storage vessel buried under the building. Water is drawn from the vessel through a second circuit which includes the evaporator of a heat pump. The output from the heat pump passes through a third circuit which contains the room heating radiators. The arrangement in three circuits enables the solar energy absorbed to be stored for a time and raises the temperature which can be obtained for the room heaters.
