Patent FR-2077786-A1 (FR)
Title: Waste water processing by aerobic fermentation
Inventor: LEFRANCOIS L A A
IPC: C02F3/12
Filed: 1970-02-13
Abstract: Waste water from agriculture, food and animal foodstuff industry, esp. from sugar factories, is processed by continuously charging, with constant flow-rate, into a fermentation container and air is continuously blown in. Homogeneity is thus maintained as regards solids, liquids and gases and max. micro-organism dispersion is achieved. Constant conditions are maintained in fermentation container. Liquid in container is converted, by air-blowing, into constant vol. expanded liquid not changing with compsn fluctuations. Content of living organic materials is raised to desired value with regard to comparable organic material, and kept constant at this value. Liquid contg organic material esp. activated sludges, is continuously drawn out of container and compsn processed in container is kept constant. For pref. processing effluent water from sugar factory, air is blown in at 0.5-0.6 m3/min. per m3. non-expanded liquid, concentration of activated sludges in fermentation container (calc. on solids) is 25-50 g/l. and temp is kept at 15-35 degrees C in container. Pref. process is interrupted before completion, and completed by another process.

Title: Rotary drum sugar drier - esp. for white sugar with internal vanes and lump breaker
IPC: C13B40/00
Filed: 1973-08-17
Abstract: The wet mass of crystals is fed by an Archimedean screw input conveyor onto a ring of spiral guide vanes on the inside wall of the rotating drum through which hot air is blown from the same end, and these propel the mass forward onto a number of rings of "trickle" vanes in the form of "dredger bucket" profiles. Centrally placed, esp. level with the first ring of these vanes, is a squirrel cage assembly which breaks up lumps of coagulated crystals falling out of the buckets as they pass over the top arc of rotation. Similarly "breakers" may follow. Simple method of uniformly dried product.

Title: Cushioning of weapon firing in bursts - can be mounted in aircraft using hydraulic means
Inventor: PIERRES GILDAS LE
IPC: F41A25/06
Filed: 1974-02-27
Abstract: Cushioning of an automatic weapon firing a bursts where shots, with exception of the first one, are triggered by the return movement of the weapon to starting position, comprising a mounting arrangement for fixing to a structure, a recoil part and mounting and braking arrangements between mounting and recoil parts to slow down the recoil. The arrangement operates the braking devices after the first shot to render it ineffective or reduce its effectiveness. This is mainly achieved through hydraulic liquid or oil in the chambers round a barrel of a weapon and spring loaded valves and piston controlling chamber inlets and outlets to enable liquid to operate either side of the recoil mechanism.
Patent FR-2266177-A1 (FR)
Title: Acceptance checker for Foucault current appts - simulates operation of appts and measures winding currents
IPC: G01R35/00
Filed: 1974-03-27
Abstract: The function of the pick-up of this type of apparatus is simulated and the effective value and frequency of the current passing through the primary coils of the pick-up are measured. An input block provides information proportional to the current flowing in the primary coil and a variable gain amplifier provides a constant amplitude output signal when its input voltage varies in inverse proportion to the frequency of an oscillator. The output of the amplifier is passed via an attenuator to a phase-lag circuit and the output from this circuit is the simulation signal which replaces the output signal of the pick-up and is passed to the visualisation unit, e.g. a CRT.

Abstract: Separation and removal of sulphite ions linked to anthocyanin dyes (I) are sepd. and removed by addn. of polyalcohol and HCl to an org. soln. of (I). Elimination of sulphite removes doubt about the toxicity of these dyes and improved stability without affecting colouring power.
Patent FR-2273769-A1 (FR)
Title: Liq. ion exchange treatment appts - with automatic regeneration when resin contracts on exhaustion
IPC: B01J47/02
Filed: 1974-06-05
Abstract: Appts is partic. intended for the softening and demineralisation of water and for the removal of undesirable colour or odour. It comprises brine reservoirs, a water treatment tank with the inlet for the untreated water and an outlet for the purified water, a treatment cartridge inside the body and a movable support for this cartridge, mounted on springs. The cartridge contains the ion exchange resins which contract as they become exhausted; the cartridge contracts in length and the relaxation in press. on the supporting plate starts the regeneration process. After a rinse, the resin again comes into operation and the flow of water to be treated is resumed. The regeneration is started simply by liq. press. and does not depend upon electrical or mechanical means.
Patent FR-2276847-A1 (FR)
IPC: A63C9/08
Filed: 1974-07-03
Abstract: A safety binding for ski boots comprising: a first holding element, mobile in relation to a ski about a vertical axis, for retaining one end of the boot; a second holding element, releasable under the action of an abnormally high vertical load, for retaining the other end of the boot; a connecting element for connecting the boot to the ski, comprising a resilient element restoring the boot to its axial position upon the ski. One end of this connecting element is secured to the ski by means of the mobile element. The binding has the special advantage of allowing the binding to release under the action of a lateral load, while keeping the boot permanently connected to the ski.

Title: Fire detector using thermistor - which is connected to base of transistor connected across centre of resistor bridge circuit
IPC: G08B17/06
Filed: 1975-05-22
Abstract: The fire detector uses a thermistor (S1), to detect an abnormal rise in temperature, the thermistor (S1) connected to the base of a transistor (T1). This transistor (T1) is connected across the centre of a resistor bridge circuit. Two FET's (T2, T3) are used to provide a differential amplifier, one transistor (T2) responding to the current variations through one of the resistors (R3) of the resistor bridge circuit, which are directly proportional to the resistance variations of the thermistor (S1). The other FET (T3) is connected to a circuit employing a capacitor (C1), a resistor (R5) and a further transistor (T3), which stores the resistance variations.

Title: Coke pushing gases extraction plant - with sectional collecting main with shutters for side/bottom inflow holes
IPC: C10B45/00
Filed: 1975-05-29
Abstract: The dust laden gases which are released during the coke pushing operations of horizontal coke ovens are collected by a collecting main which runs along the coke side parallel to the battery centre line. Square openings with the same spacing as the oven chambers are arranged in the collecting main in turn at the bottom and on the side away from the oven. The shutters for these openings are operated in groups by power actuators; they are grouped in several sections. Only the shutters of a section, where a chamber is to be pushed, are open, all other shutters are kept closed. The extraction of the dust laden gases by groups raises the efficiency, and the overall dimensions and costs of the plant are reduced. A cowl covering the coke side of the ovens is more effective and requires less expenditure than conventional cowls. The working conditions under the cowl on the coke side are greatly improved.

Title: Power converting machine using energy of ocean waves - uses rise and fall of floating body to drive rotating shaft
IPC: F03B13/18
Filed: 1976-01-20
Abstract: The machine for utilising the energy of ocean waves uses a float (10) partly filled with water (11) and having a total weight of 2500 kg. The float is attached to a chain (14) which passes over a sprocket (15) and its other end is attached to a counterweight (17). As the float (10) descends into the trough of a wave it rotates the shaft (16) and free-wheel (19) which drives the shaft (12) through the pulley (21). The free-wheel (19) operates when the float (10) rises so that the shaft (12) is only driven in the direction (R). By using a large number of such devices connected to a common output shaft, a continuous output of power can be achieved.
