Title: Pre-fabricated equipment for sewage pumping station - as compact assembly ready for mounting on concrete tank
IPC: E03F5/22
Filed: 1973-12-13
Abstract: Pumping station pre-fabricated equipment is intended for evacuating waste water and sewage from a group of new buildings constructed at a lower level than those existing and forms a means of connecting the new buildings to the main sewer. A reinforced concrete tank is placed in an excavation on the site and the waste matls. collect in the lower portion via a pipe. The top of the tank is covered by a circular cover. This cover and two electric pumps form a prefabricated assembly which is mounted as a unit on the top of the tank. The pump outlets are fixed to isolating valves attached to a horizontal manifold which has a quick-action connector to the outlet pipe. Level detectors control the upper and lower limits for te water in the tank. A lifting job is provided for raising and replacing any heavy components through a manhole. The electric cables enter and pass to the control panel. The equipment, of limited size and wt., can be stored in the ready-for-use condition and then rapidly mounted on a prepd. tank. If one pump should break down, the other will keep the station in operation.

Title: Fused joints or fittings for flexible hoses - obtd. by friction welding between compatible matls or linings
IPC: C08J5/12
Filed: 1974-08-29
Abstract: Flexible hoses are connected to branches or to in-line fittings by generating fusion joints between components which either comprise mutually compatible and partially vulcanised rubbers and plastics or include a compatible interfacial lining. Fusion may be generated by spiny welding or by axial oscillation.

Patent FR-2319405-A1 (FR)
Title: Filter process having rotating discs - with centrifugal action to clean and auxiliary filter to recover filtrate
IPC: B01D33/00
Filed: 1976-01-20
Abstract: Process for filtration of liqs. uses disc type filter elements mounted on a rotatable shaft. It has the following features:- i) the filter elements are slowly rotated during filtration, ii) at the end of the filtration cycle the residual slurry in the filter chamber is removed by the primary filter pump and fed to an auxiliary filter. iii) the solids which collect as a cake on the filter elements in a semidry state are removed by rapid rotation of the shaft, iv) finally after this mechanical removal, the residues are washed out by clean liquid. This liquid is finally filtered through the auxiliary filter by means of the primary filter pump. The elements consist of circular discs mounted inside a chamber which can be taken back. The collection shaft is coupled to a motor and the unit has a pump to meter in an auxiliary fluid contg. filter aid and a vessel to contain this. Process is useful for filtration processes where generally filter aids are used. Filter aids improve the filtration properties of a slurry. However when the cake is ultimately removed by a back flushing operation, the liquor is heavily contaminated and if discharged to an effluent stream causes blockages, contamination, respiratory dangers etc. A further problem is that cake growth is not uniform and the process does not permit the recovery of the cake in a reasonably dry condition. The filter described overcomes these problems.

Abstract: Addn. agents are fed below the slag-metal interface into molten metal being continuously cast in a mould. The addn. agents consist of a wire surrounded by a consumable sleeve sleeve. The wire is pref. fed at 5-20 metres/min. to a depth of 250-700 mm and at a distance of 50-400 mm from the casting pipie in the middle longitudinal plane of a slab mould, so that the wire melts in the lower part of the streams of molten metal flowing from the casting pipe. The pref. addn. is Ce employed as mischmetal in a tubular steel sheath; the metal being cast is pref. steel. Two or more sheathed wires may be fed into the slab mould, the wires being symmetrically located w.r.t. the casting pipe. Alternatively, the casting pipe may be located near to one narrow side of the slab mould and the wire located between the pipe and the middle of the mould. The Ce addn. improves the ductility of the steel and lowers the transition temp. of tough to brittle fracture. The invention provides uniform distribution of the Ce.
