Patent DE-4221028-A1 (DE)
Title: Used paper recycling
Inventor: SCHWARZ MICHAEL
IPC: D21B1/32
Filed: 1992-06-26
Abstract: To process used paper, for recycling, a selective flotation is used for ink removal followed by at least one further cleaning flotation stage, using a multistage flotation for the selective flotation. The collected flotation foam is gathered together at the laest after the third flotation and cleaned in a total flotation through pressure relaxation. The foam, carrying impurities, is sepd. from the clear water and removed after further thicknening if required. The foam or sludge from the final first to third flotation stages or the second stage in a double flotation, is sepd. from the coarse dirt and fibres in one or two washing stages, and the fibres are further sepd. from the dirt. The fraction with a low fibre content is given a pressure redn. flotation to separate out the fine dirt. The fraction with a fibre content, and the clear water from the total flotation, are returned to a point in front of the flotation assembly.      With a double-stage sieve action, the coarse particles in the first fraction are mostly retained. The material with a fibre content is sepd. as a third fraction at the second stage and returned to a point in front of the selective flotation. The material contd. in the fourth fraction, together with the first fraction, is passed to the total flotation.

Inventor: KESLER ROLF DIPL ING
IPC: H01L35/28
Filed: 1992-09-22
Abstract: A thermoelectric heating and cooling chamber is characterized by a large adjustable temperature range thanks to a laminated arrangement of plate-like Peltier elements, in which a first number of Peltier elements (1) having a lower capacity form a first, inner heating/cooling surface and a second number of Peltier elements (2) having a higher capacity form an outer heating/cooling surface. Both heating/cooling surfaces are separated by an overlapping intermediate plate (6) made of a good thermal insulating material, in particular stress-free cast aluminium. In order to avoid overheating the inner layer of Peltier elements (1) having a lower capacity during the heating mode, the cascade arrangement of Peltier elements (2) having a higher capacity is bridged by a bypass diode (10) polarised in such a way that in the heating mode the electrically bridged Peltier elements (2) remain currentless, or a device is provided which limits the current passing through the Peltier elements (2) having a higher capacity depending on a tolerable temperature limit on the warm side of the Peltier elements (1) having a lower capacity.

Abstract: A process for separating an intake flow consisting essentially of hydrogen, methane and C3/C4 hydrocarbons which has previously been subjected to a pretreatment, e.g. dehydration, after which the intake flow is taken through an at least single-stage partial condensation and separation into a C3/C4 hydrocarbon-rich fraction and an H2/CH4 fraction, whereafter a partial flow of the H2/CH4 fraction is mixed with the intake flow which has not yet been pretreated. The H2/CH4 gas fraction drawn from the first separator (S1) is divided into two partial flows (10, 17), the first partial flow (10) with the liquid fraction (W2) from the first separator (S1), after partial condensation (W2) being taken to a second separator (S2), the C3/C4 hydrocarbon-rich liquid fraction (16) drawn from the base of the second separator is taken with the second partial flow of the H2/CH4 gas fraction (17) from the first separator (S1) into a stripper column (S3), a highly pure H2-rich gas fraction (13) is drawn off from the head of the second separator (S2) and, after evaporation in heat exchanger (W2) against process flows to be cooled, is mixed with the intake flow (2, 2a, 2b) before its pretreatment, a C3/C4-rich product fraction (20) is drawn off from the base of the stripper column (S3) and a lower-purity H2-rich gas fraction (18) is drawn off from the head of the stripper column (S3).

Title: Maintaining constant press. in hydraulic system
Inventor: BECK FRANZ JOSEF DIPL ING
IPC: G05D16/20
Filed: 1992-12-21
Abstract: A state parameter of the lines leading from a pump (P) to load points (3) is measured after the pump output and used to influence the pump's revolution rate via a regulator (4) and control element (S), e.g. a power thyristor. The current vol. flow is measured and fed into a regulator.The regulator computes the revolution rate of the pump matching the measured vol. flow. The derived pump revolution rate is then achieved by the control element or a subsidiary control loop acting on the pump.

Title: Bore hole lifting pump with shoe seal
Inventor: KORNEV BORIS PETROVITS
IPC: F04B53/14
Filed: 1993-03-09
Abstract: The object of the invention is to specify a bore hole lifting pump which ensures a high sealing capacity of the plunger-piston couple and in which the repair intervals required during operation of the pump are extended. According to the invention, this object is achieved by the shoes having bearing pieces arranged thereon, whose cylindrical outer face matches the outer face of the shoes, by the shoes being equipped with a radial and an axial plane against which the end and inner faces of the bearing pieces fit, and by the end face of the shoes and the free end face of the bearing pieces being situated in one plane. The invention relates to a bore hole lifting pump with a shoe seal, comprising a cylinder, valves, a plunger in whose lateral surface grooves are recessed in which shoes are located which on their outer faces have the same curvature as the cylinder, and in each groove a shoe support spring. It is used in the petroleum industry for pumping liquid from deep bore holes.

Title: Lockable height-adjusting mechanism
Inventor: PAULINI MARTIN
IPC: F16B7/16
Filed: 1993-10-26
Abstract: The height-adjusting mechanisms used in tables, chairs or the like are frequently too complex for the tasks they perform, require too much material and are therefore too expensive and too heavy. The new lockable height-adjusting mechanism is to be capable of being produced with a small material requirement and low costs, is to be lightweight and is to permit a sufficiently large number of locking possibilities which are easy to set. Two hollow cylinders (1, 2) are fitted telescopically one inside the other, one (2), diametrically opposite, having cutouts (4) of different height and the other (1) having two pegs (3) which are located opposite transversely to the longitudinal axis and fit into the cutouts (4). The height adjustment is effected by lifting the cylinder (2) provided with the cutouts (4) above the pegs (3), turning it and lowering it so that the pegs (3) are situated in other cutouts (4). Used as height-adjusting mechanism in tables, chairs or the like. <IMAGE>
