Title: Separator for light liquids
IPC: B01D17/02
Filed: 1980-12-22
Granted: 1985-05-29
Abstract: The present invention relates to an apparatus for continuously separating a fluid mixture, for example, oil, water, as well as also slurry, and for continuous separate discharge of the fluids and harmless removal of the solid portion. The invention is based on the principle that the fluid mixture is conducted in the vertical direction in such a manner, that by the downward flow, flow free zones develop on the opposing sides of deflectors, in which the low viscosity fluid (oil) rises and forms a specified height oil column in the collecting chamber. The oil column so appears, as a result of a turbulence effect of the separator, to the water surface, that with a density of 0.85, 15% of the oil column floats above the water surface and 85% sinks under the water surface. These 15%'s are used for the continuous draining without the water flowing off with it. The oil outlet lies, for example, only 1 cm above the highest possible water level, the oil column under the water surface amounts to 5.6 cm before the oil discharge. Through the arrangement of a submerged second water surface independent from the water surface fluctuations this spacing is considerably increased. With obstructions in the oil discharge (filled tank, blocked pipe, etc.) the oil level in the oil collection chamber sinks and flows through the immersion pipe of the oil safety discharge in a reserve tank; through this the oil alarm is tripped.

Abstract: A launching apparatus for discharging a projectile connected to a lifeline or the like, comprising a launching tube (2) which is connected to a source of compressed air via a main valve having rapid valve movement. In connection with the launching tube, a reservoir (1) for compressed air is provided. The main valve (6, 6a) is arranged between the reservoir (1) and the launching tube (2) and has a large flow area. The valve (6, 6a) is actuated into an open position by means of a pressure-driven servomechanism which consists of a cylinder (8) and a piston (10) which is connected to the main valve (6, 6a). Inlets (27, 17) for compressed air into the cylinder space (19) in back of the piston (10) are provided, a manually-operable valve in the non-actuated position holding said inlet (17) open. On the back side of the piston (10) a compression spring is arranged which pushes the piston (10) and thereby the main valve into the closed position. The manually-operable valve has an air drain passage (18, 21) from the cylinder space (19) in back of the piston (10) which is opened when the manual valve is actuated while at the same time the inlet (17, 27) is closed, such that the pressure in back of the piston (10) disappears and the piston (10) is pushed back, the front side of the piston being open toward the compressed air reservoir (1). A projectile means for a launching apparatus for lifelines, especially an air-driven launching apparatus, has a rearwardly-open compartment (33) provided in the projectile for receiving and containing the necessary length of line (31). The line is arranged inside the compartment (33) in loops running back and forth, layer upon layer, inside the compartment. The compartment can be closed by means of an easily removable lid, to prevent air pressure from entering the compartment (33) when the projectile is fired. An apparatus for placing the line (31) inside the projectile consists of a tube (37) having a bore diameter which is somewhat larger than the cross-sectional diameter of the line (31). One end of the tube is connected to a chamber (38) having a somewhat larger inside diameter than that of the tube. A laterally-directed opening (39) is provided in the exterior of the chamber (38) for introducing the line (31) thereinto, and an inlet for admitting compressed air into the chamber is arranged above the inlet end of the tube. A perforated plate (43) can be provided at the free end of the tube (37), the primary plane of said plate lying transversely of the longitudinal axis of the tube (37). This plate is utilized when the line is being inserted into the projectile, for compressing the line.

Abstract: In a method and device for producing fibre pulp from fibrous lignocellulose containing raw material, such material is subjected to preheating in a preheater (15) by means of steam and thereafter to grinding at increased pressure of steam or gas between grinding discs which rotate relatively to one another (38, 40) in a grinding apparatus (26) into fibre pulp which is propelled from the apparatus housing (36) by means of the steam or gas into a separation device (80) which is similarly maintained under steam pressure and in which the steam is separated from the pulp. The material is conveyed not only to the preheater but also from the latter to the grinding apparatus via a steamtight conveyor (11, 22). An increased pressure of steam or gas is created at this stage in the grinding apparatus compared to that in the preheater such that the steam proceeding from the grinding apparatus to the receiving device is conveyed further by means of this higher pressure to the preheater, there being responsible for preheating the material to over 100<o>C.

Abstract: A pressure transducer for measuring the difference in pressures between two liquids, includes two very closely spaced plates (12 and 14), at least one of which (14) is a diaphragm, and opposed conductive coatings (18 and 20) on these two closely spaced plates. The space between the two plates is evacuated, and a low viscosity silicon oil is drawn in through a conduit to completely fill the space between the two plates. The conduit (44, 52) leading to the space between the plates is filled up to a certain point with the low viscosity fluid, and a thin membrane or bellows (42) tightly seals this conduit. One of the two liquids, the pressure of which is to be measured, is channelled to the outer of the membrane or bellows; and the other of the two liquids is conducted to the outer surface of the diaphragm of the pressure transducer. Two concentric capacitors are formed by the opposed conductive coatings (18 and 20, 22), with an inner variable capacitor having substantial changes as the diaphragm flexes, and the outer reference capacitor having very little change; but both of the capacitors being separated by the same dielectric liquid.

Abstract: A roller guide for use in a continuous casting installation for steel is divided into segments. Each segment includes a fixed guide member which rests on a base and a movable guide member which is supported by the fixed guide member. The guide members carry rollers which cooperate to define a path for a continuously cast steel strand. The fixed guide member has a series of hollow columns which are aligned with respective tubular elements provided on the movable guide member. Spacers for adjusting the distance between the rollers are disposed between the columns and tubular elements. A tie rod extends through each column and has a first end located externally of but adjacent to the respective column. The first end of each tie rod has a passage which registers with a corresponding passage in the base. Each pair of registering passages receives a locking pin. The locking pins connect the tie rods to the base and indirectly connect the fixed guide member to the base via the tie rods. Each tie rod has a second end located in one of the tubular elements of the movable guide member. A compression spring in each tubular element reacts against the associated tie rod and against the movable guide member thereby urging the movable guide member towards the fixed guide member. The action of the compression springs also causes the locking pins, and hence the fixed guide member, to be braced against the base. A piston-and-cylinder unit mounted inside each tubular element is arranged to act against the adjacent end face of the associated tie rod counter to the respective compression spring.
