Title: An aqueous dispersion of an amphoteric water-soluble polymer, a method of manufacturing the same, and a treating agent comprising the same
Inventor: TAKEDA HISAO
IPC: D21H17/37
Filed: 1995-12-15
Abstract: An aqueous dispersion of an amphoteric water-soluble polymer that is stably storable, easily flowable and good for handling as well as a method of manufacturing the same and its possible applications are provided according to the invention. Such an aqueous dispersion can be effectively used as a treating agent such as a chemical for flocculating and/or dehydrating raw sludge, excess sludge, digested sludge or any mixtures thereof derived from municipal sewage, human waste or general industrial waste water, or as a chemical for separating and treating oil from oil-containing industrial waste water, as a drainage aid, a retention aid, a chemical for recovering useful and valuable substances from white water in the papermaking process. The aqueous dispersion of an amphoteric water-soluble polymer according to the invention is obtained by polymerizing a mixture of monomers comprising a specific cationic monomer and an anionic monomer as essential components with stirring in an aqueous salt solution incapable of dissolving the produced polymer and in the presence of a polymer electrolyte dispersant soluble in said aqueous salt solution. Such an aqueous dispersion is highly effective when the concentration of the produced amphoteric water-soluble polymer in the aqueous dispersion, the concentration of the salt, the concentration of the dispersant, the viscosity of the aqueous dispersion, and the average diameter of the particles of the amphoteric water-soluble polymer in the aqueous dispersion are respectively found within specific ranges.

IPC: F02B75/26
Filed: 1995-12-04
Abstract: A rotary internal combustion engine of the type having pistons mounted for reciprocatory movement in respective cylinders which are arranged in equally-spaced relationship around a longitudinal axis of rotation, said axis being the axis of rotation of an output shaft passing rotatably and sealably through apertures of respective first and second end plates of a housing within which the pistons and cylinders move as part of a rotatable rotor assembly secured to said output shaft, while the pistons are simultaneously movable reciprocably in the cylinders, cam follower means being associated with each piston and adapted to coact with undulating cam track means around the housing. Cyclical combustion of fuel in the cylinders imparts reciprocation to the pistons with resultant thrust against the cam track means so as to cause rotation of the rotor assembly and output shaft. The pistons include two sets thereof each having at least two pistons, the pistons of each set being at opposite sides of the axis of rotation of the rotor assembly and output shaft and are interconnected by piston-connection means so that the pistons of each set move in unison, the parts being so made and arranged that the piston cam follower means coact with the cam track means in a manner ensuring that movement of either set of pistons in their cylinders is in the direction opposite to the direction of movement of the other set of pistons.

Inventor: FISCHER KLAUS
IPC: H05B41/295
Filed: 1996-12-10
Abstract: The invention relates to a method and a circuit arrangement for operating a discharge lamp.      In the preheating phase, the actual value of the load current is registered, a first time-invariant setpoint value of the load current, which corresponds to a desired actual value of a load current in the preheating phase, is formed, and a clock generator is activated, which runs freely at a frequency which is less than the resonant frequency of the load circuit when the lamp is off and is greater than the resonant frequency of the load circuit when the lamp is on. The preheating phase is terminated after a first predeterminable time period has elapsed. In the striking phase, the actual value of the load current in the load circuit is registered, a time-varying setpoint value of the load current is formed, and the clock generator is synchronized with the frequency of an inverter. The striking phase is terminated as soon as the setpoint value of the load current reaches a value at which an on-time of a half-bridge switching element is greater than. the period of the free-running clock generator. In normal operation. the actual value of the load current is registered and a second time-invariant setpoint value of the load current is formed, which setpoint value corresponds to a desired actual value of the load current in normal operation.

IPC: B08B9/00
Filed: 1997-03-14
Abstract: A method and system for supplying electrically conductive coating materials to an electrostatic dispenser with a parallel arrangement of subsystems selectably coupled to the dispenser by a four-port system voltage blocking valve, which electrically isolates the subsystems. The subsystems each include first and second piston cylinders that alternatingly receive a selected coating material from a corresponding manifold and supply the coating material to the dispenser by a subsystem voltageblocking valve, which isolates the dispenser from the manifold, when coupled to the dispenser. The first and second piston cylinders of each subsystem also alternatingly receive a solvent from the corresponding manifold and direct the solvent to a waste receptacle by a corresponding subsystem voltage blocking valve when the subsystem is not coupled to the dispenser. The solvent removes previously supplied coating material from the non-selected subsystem and readies the non-selected subsystem for supplying a next selected coating material to the dispenser.
