Patent FR-2214510-A1 (FR)
Title: Oxygenation of effluent streams contg. organic matl. - using pure oxygen with pumped recirculation where downward velocity is slightly less than bubble rise
IPC: C02F3/20
Filed: 1974-01-24
Abstract: Activated sludge treatment pits for effluent streams are efficiently oxygenated by pure oxygen. To avoid loss, the oxygen is introduced at the bottom of a recirculatory pump which induces a velocity in the liquor above the upward velocity of the bubbles. This sweeps them down into a diffuser zone where the velocity decreases and the bubbles remain stationary in the liquor stream. This ensures complete absorption of the oxgyen. Inert gas can be removed in a separate line. several variants are possible.

Title: Fault detector for vehicle heated rear window - probe senses presence of filament voltage through glass
IPC: G01R31/50
Filed: 1974-06-13
Abstract: The heating elements in a motor vehicle heated rear window are checked using a probe which is placed on the glass over the filaments of the element. By powering the element comparison are made between probe output and a reference to detect fault conditions. An information detector (12) receives signals from a simple detector probe which is passed over the heating element filaments. The detector output (32) passes into level detectors (13, 14) each with a different reference level applied (15, 16). The detector outputs (53, 54) pass into an AND-circuit (17) with a logic high value on a third input (18). A bistable (19) with a reset to zero input detects the logic output (55) value which is observed by a lamp (20). The circuit has driven from a power supply circuit (10) connected to the vehicle battery.

Title: Nuclear reactor pressure vessel with partially prestressed liner - obtd. by two-stage prestressing with infill concrete placed between stages
IPC: F16J12/00
Filed: 1975-06-10
Abstract: A method of connecting the metal liner of a prestressed nuclear reactor pressure vessel (e.g. of concrete or other materials) to the circumferentially prestressed wall consists of applying the prestress in two stages; in the first stage a portion (40-60 esp. 50%) of the prestress is applied to the wall but is not transmitted to the liner; then infill concrete is placed between the liner and the wall and then the second prestressing stage is carried out, applying full prestress to the wall but only partial prestress to the liner; the latter prestress is sufficient to compensate thermal stresses which arise in the liner later, during operation. Excessive stressing of the liner is thus avoided.

Patent FR-2299442-A1 (FR)
Title: Step motor control system - has impulse generation and selection according to program for sewing machine
IPC: D05B21/00
Filed: 1975-08-28
Abstract: An appts. is claimed for the control of a step motor, partic. for a sewing machine, with a drive circuit to generate activating signals to the step motor. A store holds the information on the number of impulses and the impulse sequences for the drive circuit to pass on successively. A reader extracts the stored information data, while a decoder establishes the number of impulses in a sequence. An impulse generator delivers a frequency, selected from an available number of frequencies, to match the decoded impulse information. The generated impulses are fed to the drive circuit where a digital unit stores the number of impulses through the decoded impulse sequence, with gates to end the impulse supply when the number of fed impulses matches the stored number of impulses. The system provides a simple method of activating the motor to operate at a given and determined number of rotations, at high speeds, with a positive stop action without requiring absorbers for vibration.

The bit is fixed in the head by a tangential cotter pin (14) engaging a circumferential groove (13) and is thus fixed axially yet free to rotate. The liaison between the bit (2-5) and the ratchet wheel (9) is provided by a square section bit zone (7) engaging a matching wheel hole.
Patent FR-2337599-A1 (FR)
Title: Metal sheet bonding system - using punch to form V-shaped section which is pressed flat to form overlap of sheared edges
IPC: B21D39/03
Filed: 1976-01-09
Abstract: Two layers of sheet metal may be bonded together using a V shaped punch (4) which shears through two sheets (1, 2) located on a support platten (3). The punch shears the plates at the centre and introduces a permanent elongation, but the areas at the edge of the punched area are not sheared and remain connected to the metal sheets. The V shaped elongation is then pressed flat, and the sheared edges are thus forced back and overlap the underside of the two layers of sheet. In practice, the machine automatically turns the sheet over between operations and cams synchronise the punching and pressing.
