Title: Hygrometric measuring device using impedance change - uses filters at detector probe in polluted atmosphere
IPC: G01N27/12
Filed: 1974-02-28
Abstract: Capacitive effects from the use of alternating currents are eliminated and filtes are used to effect measurements in polluted atmospheres. A hygrometer probe comprises two nickel wires wound on a cylindrical former and surrounded by fibre glass powder. It has a large impedance variation for cange of humidity level. The output of a Wien bridge oscillator is connected to the probe through a bridge divider. The probe output passes through a low impedance convertor powered from a power supply to an amplifier with a synchronous detector for measurement on a galvanometer. The detector probe is connected to the electronic unit through a screened cable.

Title: Domestic refuse compactor - has frequency dependent circuit producing signal proportional to dynamic force component
IPC: B30B15/14
Filed: 1975-06-27
Abstract: Domestic refuse compactor has ram driven through a reduction gear by an electric motor. The ram is immersed into the container accommodating the refuse and the compacting force exerted by the ram is controlled in such a manner that the compacting force is largely independent from the compressibility of the refuse components. The ram is able to exert full compacting force when compacting mixed soft and hard components in the refuse, e.g. to crush glass bottles embedded in soft refuse. A frequency dependent RC element converts the control signal so that this is proportional to the dynamic compacting force component.

Title: Engine fuel distribution control system - cuts off supply during deceleration until idling speed is reached
IPC: F02D41/12
Filed: 1975-09-17
Abstract: The equipment is particularly for internal-combustion automobile engines using liquid or gaseous fuel, limiting consumption and pollution. Fuel distribution is prevented during deceleration down to a minimum rotational speed, below which it is resumed to keep the engine running at idling speed. A solenoid valve can be used, cutting off the supply passage to the carburettor jet and operated by the speed control and acceleration and deceleration controls. A multivibrator circuit receives pulses related to the engine speed and an integrator circuit produces a voltage proportional to engine speed, a comparator operating a valve control relay below an engine speed of 1000 - 2000 r.p.m.

Title: Joining conduits under water, esp. at great depths - by weld head structure facilitating remote controlled guidance of flanges
IPC: F16L37/00
Filed: 1976-08-19
Abstract: Device for positioning a pipeline extending beneath a sheet of water from a remote situation so as to make a joint with a feed pipe from a well, at a predetermined terminal point has guiding assemblies lowered to a position close to the terminal point, and controlled from the surface. The guiding assemblies includes a winching arrangement with a funnel and a flexible cable attached to the conduit below water, so that the conduit can be moved by a winch at the surface. Controls permit the conduit to be guided along a path towards the winching arrangement and its funnel, so that initially it is fixed by the cable to the funnel where it is partially positioned relatively to the terminal point. A remote controlled motor energises the winching arrangement to move the conduit from its partial alignment to a position at which it is accurately located at the terminal point. Provides a relatively inexpensive means of joining conduits at any depth below the surface and esp. at depths at which divers cannot work. The hydraulic energy necessary may be provided if pref. from equipment assembled to the device.

Title: Cooling tower vapour cloud reduction process - reduces total water area in direct contact with atmosphere by reducing flow rate or height at which contact occurs
Inventor: RIBIER JEAN GILBERT
IPC: F28C1/14
Filed: 1976-10-22
Abstract: The process reduces the vapour cloud formed above a cooling tower when the ambient air is relatively cold and humid, the water in the tower being partly in direct and partly in indirect contact with the atmosphere. The total surface of water in direct contact with the air is reduced, typically by reducing the flow rate of the water concerned, or the height for which this contact takes place. There can be a selector device regulating the quantity of water in direct contact by diversion through a dry heat exchanger, situated below the direct contact area.
