Patent FR-2313810-A1 (FR)
Title: Gain compression circuit for electroacoustic recording - has separate manual and automatic gain controls for multi source inputs
IPC: H03G7/00
Filed: 1975-06-05
Abstract: This gain compression circuit for electro - acoustic recording consoles with many input lines derived from tape decks monitors each separately. The compression circuits provide an output to the operator warning of any incorrect compression as the recording proceeds. Each output line includes a separate amplifier with a feedback loop adjusting its gain according to the signal level. A detector sensitive to some given mean signal level of the amplifier output drives two photo - emitting diodes one of which offers the operator the option of using a manual switch control.
Patent FR-2283025-A1 (FR)
Title: Electric traction with regenerative braking - using one control pedal and switch to reverse motor field windings
IPC: B60L7/12
Filed: 1975-09-01
Abstract: The electric traction vehicle is fitted with a single pedal to control both drive and braking. When the pedal is pressed a relay connects the DC motor to the battery. If the pedal is lifted then the field windings of the motor are reversed and the electric energy generated in the motor is fed back into the battery to recover some of the energy and to provide some regenerative braking. The current flows are regulated by simple diodes and the relay is coupled to the drive pedal by a single connection. The system is ideally suited for fork lift trucks etc. and leaves the driver to control other attachments with his other foot.
Patent FR-2332922-A1 (FR)
Title: Plastic bag incorporating closure device - with two bands cooperating with two or more opposed holes
IPC: B65D33/16
Filed: 1975-11-28
Abstract: Plastic bag incorporates a closure device consisting of two bands which have been pre cut in the top of the bag and which cooperate with two or more opposed holes which are formed a short distance away from the top of the bag. To close the bag, the two bands, which are formed by score lines, are separated to form two ties each of which is then passed through the hole in the opposite wall of the bag and which are then tied together in a knot. It is not necessary to roll over the top of the bag, so that the whole of its usable volume remains available. The bag may be used partic. for packaging fruit and vegetables, or for household refuse.
Patent FR-2306083-A1 (FR)
Title: Summation link for office machine - maintains self locking position when at rest as long as driving force is inactive
IPC: B41J7/60
Filed: 1975-12-03
Abstract: The gear comprises a drive bar (1) with a knee-lever linkage (6, 7) attached to each end. In their rest positions these linkages maintain an extended position but can individually or together be moved out of their initial position by driving forces (10, 11) arranged parallel to the drive bar. In a design variation, the drive bar has an angle lever attached to each end whose one lever end has an engaging nose. The driving force is applied at right angles to the bar and one or both of the angle levers is released from its engaged position to move up against stops on the drive bar and on further movement swivels the drive bar out of its base position. The design prevents an overthrow in movement.
Patent FR-2336167-A1 (FR)
Title: Mixing of liquid and gaseous fluids - by stirrer which moves in a conical path under its own stirring action
IPC: B01F7/00
Filed: 1975-12-23
Abstract: The flux generated by a stirrer in a vessel is dispersed around the vessel by the stirrer moving round on a predetermined conical trajectory. Alternatively, the stirrer is kept in a fixed position and the flux dispersed by a deflection assembly pivoting around a fixed point of the vessel. Used for mixing of liq. or gaseous fluids. System creates local mixing energy greater per unit of volume than present systems. The couple on the shaft is reduced which allows the shaft dia. to be reduced. Anti-rotation baffles can be made smaller or eliminated.

Title: Vehicle safety belt locking device - has locking lever coupled to electromagnet energised with ignition on (SW 6.2.78)
IPC: B60R22/32
Filed: 1976-07-15
Abstract: The vehicle safety belt locking device is part of a primary electrical circuit. It incorporates a relay with adjustable time lag, and an electromagnet (8) energised when the ignition is switched on, coupled to a locking lever (3). A switch closes under a shock load in any direction which is dangerous to the user. The relay operates in such a manner that after the time lag has expired, the electromagnet is de-energised and the belt released. There can also be a safety switch, connected to the relay, so that the primary electrical circuit is switched off at the same time as the belt is released.

Title: Compressed air brake cylinder for vehicle - has pressure operating spring loaded piston which compresses seal lips to compensate for misalignment
IPC: B60T17/08
Filed: 1976-08-18
Abstract: The vehicle brake cylinder is operated by compressed air and comprises a spring loaded piston (13). The piston rod (12) is hollow and fits over the projecting compressed air inlet tube (3,7). This air passes through the annular space (27) and behind (14) the piston, the rod (15) moving a lever (16) to operate the brake (17). The piston seal (18) covers the complete piston surface, contact being maintained by the air pressure. The seal lips (22) are returned rearwards and the same pressure maintains contact with the cylinder walls (1), compensating for misalignment when operating the lever. An emergency air inlet (4) operates an auxiliary piston (30) to move the main piston.

Title: Enzymatic measurement of uric acid - using uricase and peroxidase with phenol or hydroxybenzoic acid and amino-phenazone
IPC: C12Q1/62
Filed: 1977-03-07
Abstract: The uric acid content of biological liquids is measured in an enzymatic process using uricase isolated from Aspergillus flavus, and a peroxidase. The hydrogen peroxide formed by the action of the uricase is coupled with a chromogenic hydrogen donor which is an association either of phenol and aminophenazone (1-phenyl-2,3-dimethyl-4-amino-5-pyrazolone) or of 3-hydroxybenzoic acid or its salts with aminophenazone, this association being converted by the action of peroxidase into a stable coloured deriv. which may be measured by any colorimetric or spectrophotometric method. The analyses may be carried out on samples which have not been deproteinated; measurement is rapid in ambient temp.; negative interference due to haemoglobin, bilirubin, or hydrogen-donating medicaments is minimal; and measurement may be effected manually or automatically. A typical reagent mixture contained buffers to pH 6.8-8.7, 1-300 i.u. of A. flavus uricase, 1000-15000 i.u. peroxidase, 0.1-10 g aminophenazone per litre, 0.2-20g phenol per litre, 0.1-10 mg Na or K salt of EDTA, and 0.5-10 g polyethylene glycol per litre. If the reagents are prepared in the form of tablets, these will generally contain lactose, mannitol, polyvinyl pyrrolidone, or sorbitol in sufficient quantity to give a working solution of 0.1-10 g/litre.
