Patent FR-2366789-A1 (FR)
Title: Rain cloud formation system - uses reflected light from plane mirrors to heat air in which water condenses at height
IPC: A01G15/00
Filed: 1976-09-17
Abstract: A number of plane mirrors in a group are arranged to reflect the sun's rays into the sky, all in the same direction and parallel. Air heated by the reflected rays sides and on reaching a cold atmospheric layer the water vapour in the rising air condenses and forms a cloud. This cloud saturates with continued arrival of moist rising air and finally precipitates rain. This occurs between one and three hours either side of midday.

Title: Control circuit for series thyristors - has subcircuit for each thyristor connected into ring to ensure all or none turn:on (SW 27.6.77)
Inventor: JACKSON PER OLOF
IPC: H02M1/08
Filed: 1977-03-01
Abstract: The control circuit, for series thyristors, consists of a number of subcircuits each controlling one thyristor and each coupled to the subcircuit controlling the adjacent thrysitor downstream so that a ring of subcircuits is formed. This ring is made by connecting a second output from each subcircuit to a second input of the next. The two inputs are passed via detectors to and OR-gate. Relating the ignition signals for the thyristors in this way prevents one thyristor not being turned on at the same time as the others and thereby being destroyed by overloading. It also prevents double turn-off.

Title: Motor vehicle antitheft alarm - initiates cycle on variation of battery load and disconnection of earthed wires
IPC: B60R25/10
Filed: 1977-09-05
Abstract: The motor vehicle theft alarm equipment actuates a bell etc or light when theft is attempted of the vehicle itself or of certain of its accessories, and prevents it being started. It initiates an alarm cycle on the occasion of a variation in the current demanded of the battery, and sets off the alarm immediately certain normally-earthed wires are disconnected. The alarm equipment resets automatically after an alarm cycle of set duration, and is not neutralised if the battery voltage falls under heavy load. On such a load occurring it sets off the alarm immediately, and prevents starting by shorting out the fuses or switches.

Title: Adaptive digital filter for data transmission - has adaptation divided into stages using increasing number of coefficients to increase speed
IPC: H03H21/00
Filed: 1977-10-25
Abstract: The adaptive digital filter is designed to compensate the transfer of a line of transmission comprising M coefficients. To increase the speed of convergence, and reduce the length of the acquisition phase, during which test sequences are transmitted on the line, the adaptation is broken down into successive stages. Each stage is associated with a part composed of M' filter coefficients. During each stage the adaptation of M' coefficients w.r.t. the error determined is effected by using only the M' coefficients. Increases are made in the value of M' until in the last stage M'=M.
