Title: Porous hydrophilic carbon for waste water purification - prepd. by impregnating wood strips, pyrolysing and crushing
IPC: C02F3/10
Filed: 1975-11-13
Abstract: Porous hydrophilic carbon for bacterial bed supports in waste water purification are made by cutting wood into strips 50-100 cm long, a few mm wide and 0.1-0.5 mm thick. The strips are then impregnated on their faces by an aq. liquid contg. sulphuric acid (6-7% based on the wood), an unsaturated oil or its corresp. free acid (3-6% based on the wood) and 1-2% of a detergent emulsifier of the ABS type or an etherified polyalkylphenol. The compressed impregnated wood of weight 50-60 kgs/m3 is then pyrolysed by heating to 240 degrees C in a sealed oven. The wood strips only contract longitudinally avoiding curving or flattening of the sap or resin channels. The carbon fibre is then curshed for use in water treatment. The carbon is used for treating domestic and industrial water for example from food industries, starch manufacture and abattoirs. The process has the advantage of using an anaerobic method with evolving harmful or malodorous gases; the normal aerobic processes have the disadvantage of producing large amounts of sludge which must be disposed of. A further advantage lies in the removal of nitrogen and phosphorus contg. material.

Title: Mould wash for centrifugal casting of copper alloys - in which zirconia, bonded with alumina, provides thermal conductivity and permeability
IPC: B22C3/00
Filed: 1976-07-13
Abstract: A chilled mould is coated prior to the centrifugal casting of copper or its alloys, using a suspension of powders to form a thin layer. The novelty is that to form a thermally-conducting layer which is permeable to gas, the suspension contains ZrO2 and an inorganic binder. Inorganic binder is pref. unsintered alumina, the pref. suspension consisting of water contg. fine-grained ZrO2, and the finest Al2O3 slurry, forming a layer on the internal wall of the mould with a uniform thickness of 0.1-0.3 mm. During coating with the suspension, the mould is pref. rotated at a slower speed than that used during centrifugal casting, and the mould is pref. preheated to 150 degrees C, before using the suspension. Amt. of gas inclusions on the outside surface of the casting is reduced, and the amt. of oxide and unsoundness in the bore of the casting is also reduced. Lower casting temps. can be employed so casting times are less and mould life is increased. Improvement in casting quality means that only a small amt. of the casting must be removed by machining.

By using prepd. reagents the analysis time is reduced fewer manipulations are needed and precise automatic equipment can be used.
Patent FR-2387094-A1 (FR)
Title: Depositing Stellite (RTM) on the cutting teeth of saw-blades - by forming a retractable cavity around the tooth
IPC: B23D65/00
Filed: 1977-04-15
Abstract: The formation of cutting edges on saw blades involves depositing "stellite" (RTM) on the edges of the teeth, each tooth having been previously surrounded by a retractable well of several sections which forms around the tooth a cavity for receiving a drop of stellite. A supply device continuously introduces the end of a stellite rod into the cavity while an electrolytic current is established between the rod and the saw blade to form an electric arc at the rod end. As a result the cavity is progressively filled with the stellite which melts down to the level of the arc at the same rate as the rod advances. Stellite increases the wear resistance of the saw teeth. In contrast to conventional stellite deposition techniques little stellite is lost during deposition and little operating time. The solid stellite is found to have little inherent air porosity.
