Title: Washing machine water level control - by float with magnet in a differ-ential membrane valve unit
IPC: D06F39/08
Filed: 1973-10-05
Abstract: When the water level in a clothing or dish washing machine rises beyond its normal level, it flows into a float chamber causing a float to rise carrying a permanent magnet with it. The magnetic field is then insufficient to hold a ferrous valve which drops into its seating in the water flow chamber, blocking the outlet, the rapid rise in water press. causing membranes to seal the water channel. The purpose is to provide an accurate water level monitor, with rapid cut-off in the water input, in a system unaffected by dirt or corrosion.

Abstract: Appts. for treating polymer materials, esp. an extruder has a cylinder, a die, and a rotatable endless screw for displacing the material through the cylinder, and converting it progressively from the solid phase into an extrudable liquid phase. The screw has a first helical groove which exercises a continuous pressure on the moving plastic material and has a constant width so that a constant amount of the moving solid material contacts the cylinder, and a second helical groove for continuously and progressively converting the solid phase into the liquid phase, and contacting the material with the cylinder, the liquid phase being sepd. from the solid phase, and not passing into the latter phase. There is highly efficient conversion of the solid phase into the liquid phase. An entirely plasticised, homogeneous liquid mass is produced and deterioration of the material is a minimum.

Title: Textured continuous filament yarn of fibrous appearance - has staple fibres bonded to continuous filaments and to each other
IPC: D02G3/04
Filed: 1976-06-22
Abstract: A textured, continuous filament yarn is formed from at least one endless filament to which staple fibres are bonded.

Patent FR-2333750-A1 (FR)
IPC: B67D1/08
Filed: 1976-12-02
Abstract: The fluid pressure control installation relates to the serving of beer through a manually operated tap (6). The equipment comprises a barrel (1) of beer with a cylindrical profile and flat top with spring valve sealing couplings and a side entry pipe (5) leading to a spring loaded ball valve (11) in the gas duct connected with a pressurised carbon dioxide cylinder.

Title: Gas purifier used in hot bituminous coating installation - comprises a curtain of granules and filters to absorb dust, vapours and waste heat
IPC: B01D50/00
Filed: 1977-01-07
Abstract: The appts. is inserted in the path of hot gas and prebitumated granules passing through a drum-mixer within the installation. The gases are forced across a curtain obtd. by the flow of the coating through a slot. This curtain will remove dust particles from the hot gases. The gases are also treated with a powder capable of absorbing the vapours or fumes resulting from the super heating of the mallable bitument. The treatment is completed by cylindrical filters placed in a chimney, the filters being capable of absorbing organic material, unwanted gas cpds. and mineral particles. The appts. requires neither the use of an extractor fans as in the traditional equipment nor the filtering or dust suppressing equipment previously required. This means that the cost of prodn. may be lower. The recycling of the coating before its exit from the activator, thus renewing its contact with the hot gases and allows the recuperation of heat which would otherwise be lost.
