Title: Electrical igniters for gas turbine engines
IPC: H01T13/52
Filed: 1979-09-28
Abstract: The igniter has two electrodes (11 and 17) separated over the surface of the bore (14) of a semiconductive annular element (10). One electrode (11) is mounted at the operative tip of the igniter and has an orifice (15) through which the bore (14) opens from the igniter. A capillary tube (3) extends from a supply (35) of liquid, such as water or a hydrocarbon fuel, and opens into a cavity (2). Small quantities of liquid are introduced into the cavity via the tube and electrical energy is applied to the electrodes to cause discharge within the cavity. The discharge causes a plasma to be ejected through the orifice, for igniting a fuel-air mixture externally of the igniter. The discharge causes vaporization and molecular disruption of liquid present in the cavity. <IMAGE>

Title: Electrolytic swimming pool chlorination
Inventor: KOSAREK LOUIS J
IPC: C25B9/17
Filed: 1982-05-19
Abstract: An open-cell electrolyte chlorine generator such as a type used for the chlorination of various aqueous streams including swimming pools is constructed without the use of a diaphragm or membrane isolating or partitioning the electrolyte between the anode and cathode. Instead, a gas separating plate (15) separates the electrolyte (5) above horizontally projecting electrodes (8, 9), in order to keep the different gasses generated at the different electrodes (8, 9) separated as they rise to the top of the cell (2). Aqueous buffering reagents are added to the chloride-containing electrolyte (5) to neutralize the hydroxide anions generated at the cathode (9) and to optimize the evolution of chlorine gas by stabilizing the pH of the electrolyte (5). The chlorine and hydrogen gasses produced may be separately added to the solution which is to be treated, with an optional cooling circuit (11) taking the pre-treated solution and passing it through the cell (in heat- exchanging tubing) prior to treatment with the gasses. Thus during much of the operation of the cell, only the desired product (chlorine gas) and the easily disposed of hydrogen gas must be removed from the cell. <IMAGE>

Title: Aircraft instrumentation
Inventor: BENNETT PETER JOHN
IPC: G05D1/06
Filed: 1983-07-11
Abstract: In a power margin indicator for a vectored thrust aircraft a thrust computer (10) monitors engine speed (RPM) (11) and engine jet pipe temperature (JPT) (12). Thrust computer (10) computes an actual value of thrust from known relationships between RPM, JPT and ambient air temperature (14) to provide a thrust value output (15, 16). An engine operating limit computer (17) provides outputs (18, 19) proportional to the maximum value of thrust available by computation based on known relationships between fixed parameters (100), and changing parameters (101). Thrust outputs on outputs (18, 19) therefore are set at the limiting value of thrust available with respect to JPT or RPM respectively. Thrust values (15, 16) and (18, 19) are scaled so that a thrust margin may be provided by subtractors (102 and 103) for limiting values of JPT and RPM respectively. The thrust margin values associated with each parameter are directly compared by comparator (104) and the valve closest to its limiting value (that is the lower thrust margin value) passed to display generator (105) for onward transmission to pilot display unit (106). <IMAGE>
