Title: Alternator protection and control
Inventor: WARIN JOHN WILLIAM
IPC: H02H7/06
Filed: 1985-04-26
Abstract: To detect disconnection of a local alternator from the grid supply and, in that event, to isolate it, the excitation of the alternator is controlled to reduce any difference 26 between a monitored value of a reactive component 42 of the electricity supplied by the alternator and a predetermined value. The predetermined value is selected 14,20 to be a value which cannot occur naturally in the event of a disconnection of the grid supply from the alternator system. The difference signal from 26 controls the excitation of the alternator. If the difference, in a sense in which the actual value of the reactive component would move in the event of a disconnection of the grid supply from the alternator system, is not reduced to less than a predetermined difference within a predetermined time period as detected by timer 44, the alternator system is isolated from the grid by relay 46. <IMAGE>

Title: Fluid-flow monitoring apparatus
Inventor: BAINES ROBIN PETER
IPC: G01F1/684
Filed: 1986-03-26
Abstract: Apparatus for monitoring the flow of a fluid in a tube (1) comprises first and second temperature- sensitive resistors 8,9 attached to the outer surface of the tube wall, The first resistor 8 is heated by a heater 7 mounted alongside the resistor. The first and second resistors are connected in a bridge circuit 20 with third and fourth resistors 17,18 which are not affected by the flow. Inputs of a differential amplifier 22 are connected to opposite corners 23,24 of the bridge, and the amplifier output is connected to the heater. The amplifier supplies whatever level of heating current is required to maintain a constant state of balance of the bridge, i.e. a constant temperature difference between the first and second resistors. The greater the fluid flow, the larger will be the heater current required to maintain the temperature difference, and that current therefore provides a measure of the fluid flow. A feedback circuit 27,28,29 is provided between the output and the inverting input of the amplifier. This circuit ensures a stable response, the optimum speed of response, to changes in flow rate. The apparatus may be used in a heat flow measuring system. <IMAGE>

Title: Process for applying coatings to metals and resulting product
Inventor: BARTLETT ROBERT W
IPC: B05D7/24
Filed: 1985-10-16
Abstract: Protective coatings are applied to substrate metals by coating the metal surface, e.g. by dipping the substrate metal (10) in a molten alloy of the coating metals, and then exposing the coating at an elevated temperature to an atmosphere containing a reactive gaseous species which forms an oxide, a nitride, a carbide, a boride or a silicide (13). The coating material is a mixture of the metals M1 and M2 of which M1 forms a stable oxide, nitride, carbide, boride or silicide (13) under the prevailing conditions and of which M2 (12) does not form a stable oxide, nitride, carbide, a boride or silicide. M2 (12) serves to bond the oxide, etc. of M1 (13) to the substrate metal (10). Mixtures of M1 and/or M2 metals may be employed. This method is much easier to carry out than prior methods.
