Title: Boiler cleaning process - in which pptes. are removed dry and residual water recycled before being evaporated
Inventor: HUTTER SIEGFRIED
IPC: C02F11/147
Filed: 1975-11-26
Abstract: The process comprises using a specific quantity of water which is fed into a sludge dewatering zone and neutralised (pH7) chemically, the thus-treated sludge then being passed to a storage site. The water remaining from this stage is mixed with chemicals, to produce a pH as close to 9 as possible tp ppte. a heavy metal sludge which is dewatered and passed to a storage site. The water remaining after the metal pptn. and sludge dewatering stages is recycled to the cleaning stage and the process repeated as often as is reqd. with the residual water remaining after the boiler has been cleaned being evaporated using waste heat from the boiler has been cleaned being evaporated using waste heat from the boiler. The sludges produced are dry, non-polluting and neutral easing transport difficulties and storage. A smaller quantity of water is reqd.

Title: Fritless electrodes for monolithic ceramic capacitor - prepd. from noble metal coated, pigment sized base metal particles
Inventor: HERTZ JEROME JAY
IPC: H01G4/008
Filed: 1976-08-24
Abstract: The electrodes for a ceramic capacitor comprise fritless patterns of pigment-sized base metal particles coated with a minor wt.% noble metal spaced through a sintered ceramic monolith in capacitative relationship and margined inwards from its edges, the particles being compressed against each other and against the ceramic. The capacitor is made by (a) stacking green, binder-contg. ceramic sheets with fritless electrode patterns of the particles in an adherent vehicle painted on and (b) ceramically firing in a reducing atmos. to remove binder and vehicle, sinter the ceramic into a monolith with the margined edges sintered together and compress the particles against each other and the body by ceramic shrinkage during firing. The absence of frit improves capacity as the metal particles are directly embedded in the ceramic, the intimate contact between the compressed particles and ceramic minimising resistance. The coating provides sufficient oxidn. protection to the particles to allow subsequent firing in air during terminal mfr.

Title: Mechanical and chemical waste material processing - circulating concentrates in by=pass arrangement past exchangeable monitoring probes
Inventor: MAEURER HANS
IPC: C02F9/00
Filed: 1977-01-19
Abstract: The installation removes harmful substances from industrial waste and recovers materials suitable for recycling. Monitoring of the concentrate is by exchangeable probes in a by-pass circuit. The installation consists of vessels containing the wastes to be processed. Pumps deliver the selected waste via valves into the processing reactor fitted with an agitator. The concents of the reactors are kept in constant circulation along the by-pass by a pump. Shortly before rejoining the reactor at the connection the by-pass is fitted with a monitoring vessel containing probes connected to a controller. The probes are readily exchangeable to ensure that a clean reliably working set of probes is always fitted. Reagent chemicals are added to the solution in the reactor. The fully processed concentrate is drained at a connection and a pump discharges it into a filter. The fluid part leaves the filter and the solid part for recycling leaves at another point.

Title: Raising porosity of propellants for non-encased munitions - by impregnating with water, freezing and evaporating water
Inventor: REDECKER KLAUS DR
IPC: C06B21/00
Filed: 1977-01-19
Abstract: The porosity of propellants for non-encased munitions based on propellants resistant to high temp. is increased by using propellants contg. water, cooling these at below the f.pt. of water for long enough to solidify the water, and then evaporating the water.
