Patent FR-2400489-A1 (FR)
Title: Biological purification of waste water - includes oxygenation, degradation, nitrification and denitrification steps
IPC: C02F3/00
Filed: 1977-08-17
Abstract: Waste water is treated continuously by first decanting off from sludge, then charging it with oxygen. The liq. with oxygen dissolved in it is then aerobically treated to cause degradation of the substances in it, further aerobically treated to convert nitrogenous material into nitrates, and then, after de-gassing, treated anaerobically to decompose the nitrates, free nitrogen being filtered. The flow is regulated by analysis of the purified water, partic. w.r.t. its chemical oxygen demand. The process can be conducted under press. The biological degradation and other treatments are conducted using specific bacteria for the various stages. The bacteria used can also be adapted to other components of the treated water, e.g. S and sulphites. The process overcomes lack of response to variations in flow rate, incapability of treating feebly charged effluents, and lack of elimination of nitrogenous cpds., these difficulties being caused by the low oxygen transfer capacity of previous systems. Installations used to effect this process are very flexible in operation.

Title: fibre=optic positioning within connector - is by sprung sphere slightly recessing fibre end face
IPC: G02B6/38
Filed: 1978-10-11
Abstract: The positioning of an optical fibre without a connector ensures that the end face is set square to the connector axis without damaging its surface. Positioning is based on the use of a sprung (34) sphere (29) bearing on the fibre (14) end face (38). The sphere size determines the extent to which the fibre is recessed within its holder, normally a few tenths of a millimeter. The connector consists of a tube (12) within which is held, at the mating end, a centralising annulus (14) pref. of an industrial sapphire style medium. The annulus internal dia. matches that of the fibre opening out (18) towards the rear face to ease insertion. The fibre end face is set up by the sphere carrier in a holder (21) which slides within the outer cylinder (11) of the connector.
Patent FR-2441879-A1 (FR)
Inventor: ESTRABAUD STEPHANE
IPC: H02P8/00
Filed: 1978-11-17
Abstract: The invention comes within the field of equipment control. A method of shifting a moving unit from a first position to a second position by means of a stepping motor driven by a finite sequence of pulses, said moving unit being liable to oscillate about its equilibrium point, characterized in that as a function of the period and of the damping factor of the oscillation, the time intervals which separate said pulses are chosen so that the last pulse is applied to the motor at an instant when the oscillation resulting from the set of preceding pulses brings the moving unit substantially to the required final position and reduces its speed substantially to zero. It applies in particular to disc-type printers.
