Title: Generator for wind driven electricity generator - drives shaft at constant speed in first stage and then fitting electrostatic dynamo
IPC: H02N1/08
Filed: 1977-03-18
Abstract: A generator which is specially suitable for windmills, where the kinetic wind energy is converted into electrical energy. The generator can transmit a high voltage and the power is supplied in the form on an alternating current. The reasonably high power can be supplied for a low angular velocity. The conversion is effected in two main stages. The kinetic wind energy is converted into a shaft rotating at a constant speed using a conventional regulator. The second stage involves fitting an electrostatic generator straight onto the shaft. The generator consists of two series connected capacitors, one of which has a high capacity and the other has a capacitance which varies with the speed; the current is picked off via carbon brushes.

Title: Gas fired water heater with exhaust gas fan - has temperature controlled damper regulating combustion air flow
IPC: F23N3/06
Filed: 1988-01-06
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.

Inventor: EDENS LUPPO
IPC: C12C5/02
Filed: 1988-08-24
Abstract: The oxidative deterioration of water-containing products for human consumption, e.g. beverages and oil and/or fat based products is minimised by introduction of immobilised yeast. Yeast is immobilised in and/or on a solid material which allows only very slow penetration by water. Thin layers material of such a yeast-bearing solid, e.g. paraffin, wax, can be applied to the lining of crown corks. The yeast will retain sufficient viability, even after pasteurization of the contents of a container closed with the crown cork. The yeast will minimise the oxygen concentration in the contents between the time of pasteurization and eventual consumption of the contents.
