Title: Fire and explosion suppression
Inventor: DUNSTER ROBERT GEORGE
IPC: A62C35/64
Filed: 2002-03-28
Granted: 2004-11-10
Abstract: A fire and explosion suppression system comprises a source (5) of high pressure water which is fed to a misting nozzle (13) or other water mist generating means at one input of a mixing unit (6), and a source (14) of high pressure inert gas, such as nitrogen, which is fed along a pipe (20) to another input of the mixing unit (6). Inside the mixing unit (6), water mist, in the form of an atomised mist of very small droplet size is mixed with the pressurised gas and exits the mixing unit (6) at high pressure and high velocity along a pipe (22) and is thence discharged through spreaders (26, 28). Separation of the mist production from the actual discharge of the mist, and the entraining and transporting of the mist between these two stages at high pressure and high velocity, produces an output mist of very small droplet size which is carried by the entraining and transporting high pressure gas into the area to be protected, enabling a total flooding capability.

Title: Air motor
Inventor: MA THOMAS TSOI-HEI
IPC: F01B17/00

Granted: 2013-11-06
Abstract: An air motor is described having a variable volume air chamber 10 controlled by a reciprocating piston 12, intake and exhaust ports to and from the air chamber 10 controlled by respective cyclically actuated intake 14 and exhaust 18 valves for receiving compressed air from a compressed air storage tank 20 and discharging expanded air to the ambient atmosphere. The air motor is characterised in that it operates according to a four stroke cycle with an additional pair of air metering strokes prior to the expansion and exhaust strokes of the air motor, the pair of air metering strokes comprising an intake stroke during which compressed air from the compressed air storage tank 20 is admitted at substantially constant air tank pressure into an increasing volume of the air chamber 10 and a return displacement stroke during which some of the admitted compressed air in the air chamber 10 is returned at substantially the same air tank pressure from a decreasing volume of the air chamber 10 back to the compressed air storage tank 20. The pair of air metering strokes controls the quantity of compressed air retained in the air chamber 10 at the beginning of the expansion stroke of the air motor by the difference in mass flow transferred into and out of the air chamber 10 during the intake and return strokes respectively.

Granted: 1982-11-17
Abstract: An electrochromic display cell has several electrode segments 1 spaced from a common counter-electrode 3 by an electrolyte 2 and disposed to represent different symbols according to those segments on which a coloured or effaced state is conferred by application of a current in one direction or in the other between the segments and the counter-electrode. To achieve one of the current directions a bias voltage provided by a generator 16 is applied for a fixed time by a switching circuit T1, T2 to a field-effect transistor T6 which completes a circuit through the cell 4, electrode 3, electrolyte 2 and segment 1. The transistors 6 have channel widths proportional to the segment areas so that all segments receive the same charge per unit area. The segments whose state is to change in the other direction are short-circuited with the counter-electrode by transistors T7. The display is particularly useful for the display of time data on watches.
