Title: Microphone amplifier with phantom power
Inventor: FRINDLE PAUL ANTHONY
IPC: H03F3/45
Filed: 1995-07-31
Abstract: The microphone amplifier comprises two complementary signal inputs each being connectable to a microphone via a respective phantom power blocking capacitor 30. One or more amplifying stages 210, 220 for amplifying differential signals at the signal inputs provide two complementary output signals, the amplifying stages providing a common mode gain substantially equal to unity for common mode signals at the signal inputs. The output signals are combined by resistances 150 to generate a common mode mix signal that is coupled by capacitor 180 and resistances 102, 104 to each of the signal inputs. By providing bootstrapping of a common mode signal in this way, the common mode impedance of the circuit can be increased and so the effect of mismatch in the dc phantom power blocking capacitors can be reduced.

Title: Composition for disinfecting and for inhibiting scale
Inventor: FREDERICKS STUART MARKHAM
IPC: C02F1/76
Filed: 1996-05-18
Abstract: An aqueous composition having a pH of more than 9 consists of a stabilized chlorine dioxide precursor, an alkali metal polyphosphate and an alkali metal hydroxide. The stabilized chlorine dioxide precursor is a solution comprising sodium chlorite/chlorate stabilized with sodium carbonate. The polyphosphate contains a mixture of dimer and other polyphosphates having an average 'polymer' length equivalent to a tetramer. The alkali metal hydroxide includes KOH, NaOH and NH OH. The method of forming the solution involves adding the alkali metal hydroxide to a solution of the polyphosphate in order to raise the pH, adding the chlorine dioxide precursor and adding additional alkali metal hydroxide to raise the pH to above 9. In use, an acid such as HC1, H* small Greek omega *PO  or citric acid is added to the solution to lower the pH to less than 7 and the solution is then injected into the water to be treated. The composition acts as a disinfectant, threshold scale inhibitor and corrosion inhibitor.

Title: Acceleration sensor apparatus for vehicles
Inventor: KOKETSU EIJI
IPC: B60R22/40
Filed: 1997-01-30
Abstract: Upper and lower weights 28 and 72 are located above and below the swing axis 0 of a sensor apparatus to maintain it in an upright condition so that it can detect an acceleration acting on a vehicle in a predetermined direction, regardless of the tilt of the vehicle or changes in the orientation of the apparatus relative to the vehicle, in order to permit locking of the seat belt retractor R. The apparatus is also capable of locking the retractor R when the vehicle tilts more than a predetermined angle. A sensor housing 10 is fixed on the retractor R, and swingably supports a sensor bracket 12 about an axis O parallel to an axis of tilt 01 of the seatback S. An inertial body 34 is movably supported in a support depression of the sensor bracket. When the inertial body 34 is forced up the sloping surface of the depression, an output interlock member 40 pushes tooth 68 into the toothed gear 64 of the retractor R to prevent its rotation. When the sensor bracket 12 swings more than the predetermined angle, a forcible driving member 70 pushes the stopper member 66 to engage its tooth 68 in the gear 64.
