Title: Electrolytic plant for water purificn. - with electrodes comprising piles of iron rods and using periodic changes of polarity
Inventor: MIQUEL JACQUES
IPC: C02F1/463
Filed: 1976-10-12
Abstract: Electrolytic plant for the treatment of waste water and sewage coagulates the impurities it is desired to remove from the effluents. The electrodes are arranged in a tank between vertical non conducting spacing rods. A grid is fitted above the base of the parallelepipedal tank. The plastic vertical rods are arranged in rows and define distinct gaps for iron rods. The distance between the concrete-reinforcing iron rods. The distance between the rows is equal to twice the dia. of the iron rods. Each electrode consists of two adjacent piles housed in the same gap. Electric current is supplied through a rectifier and the polarity is reversed periodically e.g. after every 10 mins. Effluent enters the tank at one position and purified leaves at the top of the other end of the tank. Any debris falls through the grid to the bottom of the tank and floating sludge is raked from the top. The process reduces the vol. of the sludge and can be operated over a wide pH it does not increase the salinity and regulation is simple. The electrodes are cheap and are easily fitted into the treatment modules.

Title: Detergent pump operated by water pressure - supplies detergent and water in correct proportions for washing metal articles
IPC: F01L21/04
Filed: 1977-02-23
Abstract: Water pressure is used to actuate a pump supplying detergent to a plant for washing metal articles. The pump has a cylindrical body (1) which houses a piston (46) biased by a spring (13). Water at high pressure enters the inlet ports (31) and pushes the piston (46) upwards by overcoming the force of the spring. On reaching the top of its stroke the ball valve (32) is pushed off its seat (33) by the central pillar (19). This causes the water pressure inside the cylinder (40) to drop suddenly so that the spring (13) returns the piston (46) to its initial position. With each stroke of the piston (46) detergent is drawn in through the valve (24) and expelled through the valve (25).

Patent FR-2375389-A1 (FR)
IPC: D21D5/22
Filed: 1977-12-22
Abstract: To discharge impurities from fibre suspensions intended for paper making, there is a chamber (8), in which a filter basket (7) is located. A vortex tube (1) which can be shut off opens into the upper end of the filter basket, and the lower end of the filter basket is connected to a dirt outlet port (5) which can be shut off. A scavenging-water feed line (9) opens into an annular space surrounding the filter basket (7) in the chamber (8). A run-off line (11) extends away from the chamber (8). Impurities which occur are trapped in the filter basket (7). The scavenging water is taken off before the dirt outlet port (5) is opened. The water present in the chamber (8) can thereby be recovered and the water consumption consequently reduced considerably.

Patent FR-2381576-A1 (FR)
IPC: B21C23/26
Filed: 1978-02-23
Abstract: In the method, relatively hard profiled strips (1, 2) are fed in a straight line through the guide channel (15) of a guide mandrel (14), the said channel extending to just in front of the forming aperture (21) of a die (11). Plastically deformable metal (M) is introduced in the form of strands between this mandrel and continuously moving friction surfaces, these being provided on wheels (4, 5) for example, and forced through the die by the friction forces of the said surfaces. This process gives rise to two separate composite profiles (P1, P2), which can be separated easily and can be used, for example, as conductor rails with relatively hard contact surfaces. In the production of composite profiles, the relatively hard profiled strips (1, 2) of which have an arched cross-section, a supporting bar (30) is used. The hitherto customary deflection of the profiled strips (1, 2) is no longer required and it is thus possible to process relatively rigid profiled strips.
