Title: Quay wall construction from precast concrete piles - which are rapidly cured by heating and transported by barge
IPC: B28B7/42
Filed: 1974-07-10
Abstract: A concrete plant is erected at the edge of the stretch of water where the quay is to be constructed using a series of precast concrete piles. Concrete is poured into a number of moulds corresponding to the number of blocks required for a single pile. The hardening process is accelerated using electric heating and the blocks can be handled after approximately six hours. Once the concrete has set, the heating is disconnected and the blocks are allowed to cool down which takes about eight hours. A crane is used to lift the blocks onto a barge, although it is within the scope of this invention for the moulds to be placed on the barge prior to the concrete being poured. Once on site, the moulds are removed and the blocks put in place, the barge returning to the plant for another load.

Title: Interpretation of visual data from aircraft or satellite - using computer to calculate co-ordinates of selected point using sensor position data
Inventor: LAGRAVE PIERRE
IPC: G06T1/00
Filed: 1974-07-22
Abstract: The remote sensing equipment (2) scans the earth's surface or clouds and the data received is treated on the ground to produce views which can be examined and interpreted by an observer (5). The interpretation is aided by presentation of the views on a graphical transcription apparatus (7) which provides the coordinates of a point chosen on the view by the observer. Information on the parameters defining the instantaneous position of the aircraft or satellite (1) is sent to a computer (8) together with the coordinates of the point selected by the observer. The computer (8) then provides the real coordinates of the point selected taking account of the position (1) and of various aberrations e.g. optical. An on-board clock (4) ensures synchronism.
Patent FR-2282185-A1 (FR)
Title: Alternator voltage regulator - has photoresistor across the field winding to regulate output
IPC: H02P9/14
Filed: 1974-08-13
Abstract: In this control circuit for an alternator, a photoresistor is connected across the field winding in series with a variable resistor. A relay, which switches the alternator output, is connected across the collectors in series with a variable resistor and a lamp which excites the photoresistor. As the alternator output, and therefore the lamp brightness, varies, the photoresistor has an inverse effect on the field current, thus giving a regulated output. If the lamp fails, then the relay is tripped so that the output is disconnected and the alternator's field current is reduced by the photoresistor to avoid over-voltage conditions.
