Patent FR-2497939-A1 (FR)
Title: Machining of cooling passages along length of plate - includes cutting slot, to allow machining of passage, and wedging slot with strip subsequently fused in plate
Inventor: BOST JOSEPH
IPC: B23P15/26
Filed: 1981-01-14
Abstract: The cooling passages in a plate heat exchanger are formed by machining from a solid plate rather than by the fabrication and brazing techniques normally used. Passages are machined along the length of the plate and the machining access slot then filled and sealed. A shallow groove (2) is cut into the surface of the plate along the line that the cooling passage (3) is to take. This groove then allows passage of a cutting tool entered at the end of the plate and moved through the length of the plate to form a circular section cooling passage (3). A rectangular section metal strip (4) is then wedged along the length of the access slot, and is welded in place, sealing the cooling passage. The face is then machined flat, and the plate heat treated to relieve internal stresses. The process can be used for the cooling of ion accelerating plates in which case the plate is perforated by a large number of holes for the passage of the ions. The cooling circuit closely follows the contours of the holes to provide maximum cooling.
Patent FR-2498787-A1 (FR)
Title: Station watch alarm system - cooperates with conventional radar system and uses echo width discrimination and echo verification to exclude spurious signals
IPC: G01S13/04
Filed: 1981-01-23
Abstract: The watch zone of the system is established by a variable range gate and a variable azimuth gate operating upon radar signals to render an alarm circuit inoperative as long as target signals or radar echo signals are received from the watch zone. Echo width discrimination and echo verification discrimination (repetition for a predetermined number of scans) are employed to exclude spurious signals from operating the systems. By establishing a watch zone of predetermined location and extent to encompass a fixed object, any material change of physical location of a vessel carrying the present invention will cause the alarm to sound or otherwise execute an alarm so that corrective action may be taken, and, in fact, must be at least considered. The least action to be taken is the turning off of the system, if no other action is required.

Title: Electronic vehicle fuel gauge - detects resonance frequency of immersed membrane vibrated by VCO and amplifier circuit to provide continuous read=out
Inventor: ROCHEREAU JACQUES
IPC: G01F23/296
Filed: 1981-07-03
Abstract: The appts. contains a tube (6), placed inside the tank (1), and closed at one end by a membrane (11) which can freely vibrate. An electrical component (12), e.g. a piezoelectric component, vibrates the membrane (11) by scanning a frequency band which contains the resonance frequency of the membrane (11). A sensor is connected to a circuit to detect the resonance frequency. This detecting circuit is connected to a counter which measures the time between the start of the resonance and the start, or the end, of the frequency scanning. This time is converted into a volume or level indication. If the fluid level is subject to rapid fluctuations, a number e.g. 10 measurements are taken and the results are stored in a memory for averaging.

Filed: 1981-11-16
Abstract: The retracting cantilever beam is used, suspends power tools in an engineering workshop, comprising two arms (4,5) connected at an articulated elbow joint (8). The inner arm (4) is connected to a wall mounting (11) or a column by a second articulated joint (7) and the joint axes are inclined to the vertical, the arrangement causing the beam to pivot back to the retracted position when released. A stop may limit the movement of the outer arm as it takes up a nominally offset retracted position under the inner arm, the inclination of the root axle (7)being adjustable to either side of a vertical mean. The root axle may be mounted on a plate (13) which can pivot about an horizontal axis (12), pivoting being effected by adjusting screws (21,22).
