Title: Filling system for liquefied gas container - detects liquid level by ultrasonic wave reflection time using reversible transducer
IPC: G01S15/88
Filed: 1974-01-25
Abstract: The system is particularly for use with liquified gas, and incorporates a reversible ultrasonic transducer mounted underneath the vessel to be filled. This emits ultrasonic waves in the vertical direction, and picks them up after reflection from the interface between gas and liquid. During the filling operation the time for emission and return of the ultrasonic wave is monitored, and filling is stopped when this time reaches a preset value. This system can also be used to allow transfer of the gas to the vessel to start when all is in order. An electronic unit can be connected between transducer and filling controls to cause these to shut off when the vessel is full.

Title: Automatic sampling device inside pipeline - for delivery of prod. into sterilised flask for bacteriological analysis
IPC: G01N33/04
Filed: 1976-01-30
Abstract: Automatic sampling device for bacteriological analysis, esp. of milk, comprises a flask with means for fixing it to the pipeline carrying the liq. to be analysed. The sterilised flask is placed vertically under the pipe and held in position by a stirrup passing under its base and fixed to the pipe at two diametrically opposite points; the flask is thus maintained against an elastic sealing ring. Sampling is effected by two needles which are moved from the rest position (A) to the working position (B) by the rod of an electrovalve. The upper orifices of the needles open into the pipe through funnels; one can be directed upstream and the other downstream so that the liq. circulating in the pipe causes the press. to be higher in one needle than in the other. In the (A) position, the liq. passes through the upstream needle and is sucked back by the needle, rinsing the passages in the process. When moved into the (B) position, shown by the dotted lines, the lower ends of the needles pierce the membrane and penetrate into the flask so as to inject the liq. to be analysed. A representative sample of a large vol. of liq. passing through a pipeline can be collected for analysis before the liq. is sold. All possible sources of contamination, such as pumps, taps etc., are avoided.

Title: Pulse generator for IC engine ignition system - has two shafts, one driven by engine and centrifugal advance mechanism for driving second shaft
IPC: F02P5/07
Filed: 1976-09-08
Abstract: The advance mechanism rotates the second shaft through an angle between two end positions, the rate of advance depending on the first shaft speed. The rate of the permitted angular movement between the two shafts is increased in such manner that the centrifugal advance mechanism is effective over a greater range of the first shaft speed. In addition to the two springs of the pulse generator, a third spring becomes effective between the two shafts in such manner as to oppose relative angular movement of the two shafts. The third spring becomes effective only at given speeds in a way, in which the three springs in mutual connection determine the relative angular movement of the two shafts at the high speed end of the increased range.

Title: Localising divers or equipment near offshore structures - using mathematical appts. to deduce coordinates from times taken for signals to travel from position to transducers (BR 13.6.78)
Inventor: SAINTENOY EDMOND
IPC: G01S15/74
Filed: 1976-11-24
Abstract: A method of localising divers or under-water equipment in a space in which there are obstacles, partic. near an off-shore structure comprising columns, consists of placing three transducers in a horizontal reference plane and a fourth transducer outside this plane, defining a second reference plane. The diver, or the equipment, is supplied with an emitter. Th times taken for signals from the emitter to reach the transducers are treated by a mathematical appts. which allows the co-ordinates of the diver or equipment to be deduced, as a function of the speed of sound in the medium and of the distance between the transducers. The values of the elements of the projection on the planes of reference of the triangles formed by the four transducers and the emitter are determined. A group of two adjacent triangles defined by three transducers and the emitter defines a coordinate element. Ageing of off-shore petroleum installations demands more supervision as the equipment becomes older. Process solves problems posed when these controls have to be carried out at great depth, over 100m. and in poor visibility, where existing methods are not applicable.
