Title: Telephone line states detection and coding - includes signals from which local conversation transmissions are detected
Inventor: PRUDHON LUCIEN PIERRE EMILE
IPC: H04M3/36
Filed: 1974-01-11
Abstract: Detection and coding of telephone line states is employed in traffic observation equipment to determine traffic flows. Direct and alternating signals on two lines are detected and a third line is observed to detect local conversation transmissions. a number of telephone lines are connected to an autocommutator and lead to a number of locations. Electrical signals on the lines are sensed to produce four output signals which are passed into the respective multiplexer. The multiplexers are addressed simultaneously in random or cyclic manner to permit selection of the representative of each line. Impedance matching ensures a further stage of isolation after which the signals are amplified and then detected and coded.

Title: Burner using liquid butane fuel - air preheated in jacket and mixed with fuel by paddle wheel
IPC: F23N1/02
Filed: 1974-02-20
Abstract: A burner fed with air and butane gas, the latter in liquid form stored in a suitable container and under pressure, has a valve for each supply line, interconnected to ensure the correct gas/air mixture, and the air supply passes through a jacket around the burner tube before mixing with the gas near the entry point into the burner tube. Around this entry point is mounted a cylindrical, tangentially bladed turbine wheel through which the gas passes, while the air is distributed over the periphery of the wheel, ensuring, good mixing of the air which has been previously preheated while passing through the jacket. The arrangement ensures that the temperature of the gas/air mixture will not fall below 0 deg.C, thus prevents frosting.

Title: Wine-making vessel with level-controlled wine delivery - employs level-actuated valve, or siphon or overflow on wine outlet
IPC: C12G1/00
Filed: 1974-05-16
Abstract: A winemaking vessel is claimed in which the fermentation chamber is connected directly to the wind outlet which pref. comes into action automatically to discharge wine as soon as the contents of the fermentation chamber rise to a predetermined level; this may be achieved by fitting in the outlet line a solenoid valve actuated by a level-detector, or the outlet may be via a siphon which runs only when the level is reached. A further solution is to fit a riser chimney inside the fermentation chamber, an overflow from the chimney leading to the wine outlet. When the wine outlet operates via automatic valve or siphon, the outlet can have an adjustable level feed pipe inside the fermentation chamber.

Title: Centrifugal compressor impeller - has radial blades inclined to rear base of impeller and non-radial outflow
Inventor: POULAIN JEAN
IPC: F04D29/28
Filed: 1974-08-14
Abstract: The impeller vanes (9) are integral with the impeller back plate. The vanes are not quite radial and are shaped as strips of even thickness, and are curved slightly as the outer edges.

Title: Stabilisation of vibrated fusion crucible with lid - by applying vacuum to dead space between seating ring and oscillating support
IPC: B01L3/04
Filed: 1975-02-28
Abstract: A fusion crucible fitted with a lid and resting on an oscillating crucible older has a ring of the same material as the crucible welded to the base of the crucible. The space inside this ring between the crucible and the support is connected to some means for evacuating this space. The lid, which is made of metal different from that of the crucible, is supported above the oscillating pan with just enough play to prevent contact between lid and crucible. Used for obtaining vitrified beads of certain types of samples, e.g. slag or cements, so that quantitative analysis for spectrometry of fluorescence 'x' can be carried out. Prevents the sticking together of lid and crucible due to diffusion of the metals at high temp. and avoids early deterioration due to remodelling after such operations. Allows the lid to be made in a metal different from that of the crucible.
