Porous building materials are protected against growth of algae and lichens by treating first with a solution of a copper salt and then with a soap solution.

1. A process for the treatment of acid waste water containing aluminum and iron, wherein (a) the acid waste containing small amounts of colloidal silicic acid is heated to just below boiling point so as to precipitate aluminum hydroxide and hydrated iron (III) oxide and is neutralized with calcium oxide and/or calcium hydroxide ; (b) the resultant aluminum hydroxide iron (III) hydroxide precipitat...

The pallet of the invention includes a load deck supported on pallet feet or spacers. The spacers of the invention are metal sleeves, each with a serrated upper edge, the entire length of which is pressed into the wooden load deck to substantially the entire depth of the serrations. The serrations may be alternately set in opposite directions, and function to prevent turning and lateral movements ...

The plant is a tank (10) forming an aeration chamber in which waste water is treated with active sludge and is aerated, and which has mounted therein a plate insert (24) defining an upwardly open secondary sedimentation chamber having inclined side walls and an overflow for purified waste water (40) as well as a bottom opening (25) through which precipitated sludge flows back to the aeration chamb...

The cleaning of anodised aluminium, for example large-area facades, presents difficulties if the surfaces are affected by firmly adhering dirt and corrosion products since the anodic oxide layer must not be attacked when such impurities are being removed. To clean such surfaces, use is made of an acidic aqueous solution having a pH of 0.8 to 3 and containing 0.1 to 10 % by weight of at least one a...

New antibiotic compounds, Fortimicin factors D and KE are produced by fermentation of microorganisms belonging to the genus Micromonospora. The antibiotic compounds are accumulated in the culture liquor and are isolated therefrom. A semisynthetic method of producing Fortimicin KE utilizing Fortimicin D is also disclosed.

The novel compounds of the formula (I) in which the substituents are defined in Claim 1, are obtained by fermenting a C-076-producing strain of Streptomyces avermitilis in an aqueous nutrient medium containing an assimilable source of carbon, an assimilable nitrogen source and inorganic salts under aerobic conditions and isolating C-076 from the fermentation broth. The novel compounds can ...

In order to achieve an exponential mixing characteristic in which simple shear mixing is repeatedly interrupted b...

PURPOSE:Aimed at is to obtain a step by which enclosing work is easy enough and the accurate enclosing is ensured without any need for extra processing such as drilling a special hole in the cylinder container.

An apparatus for installing reinforcing bottom cups on blow molded plastic containers includes a transfer arm which grasps the outer peripheries of a plurality of molded hollow containers, such as bottles, by suction means, transfers the thus held bottles to a first station at which previously adhesively coated bottom cups are pushed upwardly on to the bottoms of the containers, from which station...

The invention relates to an automatic injection device comprising a discharge mechanism, a cartridge holder and a cartridge which is slidably accommodated in the holder, the cartridge comprising a glass ampoule having an injection needle connected thereto. A sheath of shrinkable plastic sheet is shrunk around the ampoule entirely or for the greater part thereof.

PURPOSE:To obtain an ink jet having a thin thickness of a head, by laminating a reinforcing member having high elastic modulus at a part corresponding to at least a pressurizing camber of a head substrate, wherein the pressurizing chamber, a nozzle, and the like are laminated between a piezoelectric element and a vibrating plate. CONSTITUTION:In the surface of a head substrate 1 made of an ABC res...

Condensation curable silicone release compositions comprised of a silanol functional base polymer, a crosslinker containing silanic hydrogen, a precious metal catalyst such as platinum or rhodium, an optional carboxylic ester inhibitor and silicone vinyl gum cure accelerators effective for allowing thermal cure at relatively lower temperatures while minimizing the necessity of excess metal catalys...

PURPOSE:To save the inverted transmission and to decrease the transmission time, by using a transmission format added with a redundancy bit for the initial transmission data bit as the code transmission on a transmission line having excellent transmission quality.
