Title: Arrangement for protecting marine installations against icebergs
IPC: E02B17/00
Filed: 1984-09-19
Granted: 1986-05-07
Abstract: The invention relates to an arrangement for protecting founded or floating marine installations, e.g. artificial islands or the like, against drifting icebergs. This arrangement consists of one or more fenders at least partly surrounding the installation at a distance. In order to design such an arrangement in such a way that it is as simple as possible in its construction and is cost-effective and is also simple and reliable in its functional and operating mode, the fender is formed according to the invention by a self-buoyant floating body (5) which in its floating position is anchored to the sea bed (9) and/or to to the marine installation (1, 2, 3) by a number of anchoring chains, ropes or the like (6) which are loosely tensioned starting from the fender float down at an angle towards the sea bed and towards the installation. This loose tensioning is to be such that the fender float is movable in all six spatial degrees of freedom from its initial position, existing without an external pushing action on it, but also assumes a centrally symmetric neutral position relative to the marine installation to be protected. <IMAGE>

Title: Seed-spacing drill
IPC: A01C7/04
Filed: 1989-01-31
Granted: 1990-03-22

Patent DE-3920868-C1 (DE)
IPC: C03B9/193
Filed: 1989-06-26
Granted: 1991-01-10
Abstract: Parisons of glass are pressed between a hollow mould and a plunger (10). The mould has an inner wall which is complementary to the outer side of a parison. The plunger (10) has an open-pored plunger head (11) with a surface (24) which is complementary to the inner side of the parison and an inner cavity (15) which is filled with a liquid. During each working cycle, a portion of the liquid evaporates due to heat transfer from the glass to the plunger head (11) on the surface (24) of the latter, producing a separating layer of vapour between the latter surface and the glass. The liquid pressure in the cavity (15) of the plunger head (11) is in each case adapted to the pressing pressure prevailing in the glass during pressing, until the glass has reached its dimensional stability required for withdrawing the plunger head (11).

Patent DE-4034497-C1 (DE)
IPC: C01F11/46
Filed: 1990-10-30
Granted: 1992-02-13
Abstract: The process for purifying gypsum suspensions, particularly those formed in a flue gas desulfurizing plant, includes feeding the gypsum suspension (9) to a first hydrocyclone (1), which is operated to produce an underflow (11) with a comparatively high underflow concentration and an overflow fed to a collecting tank (2). The underflow (11) of the first hydrocyclone stage is further diluted to a form another underflow with a lower solids content in a suspension tank (3) and then is fed to a second hydrocyclone stage (4), the overflow of which is also fed to the collecting tank (2). Depending on purity of the gypsum required or attained, the gypsum contained in an underflow (14) of the second hydrocyclone stage (4) is either immediately dewatered and removed or is first fed to one or more hydrocyclone stages, which operate analogously. The combined overflows (15) of the first and second or further hydrocyclone stages are fed from the collecting tank (2) to a third hydrocyclone stage (6). In a thickener (8) solid particles are removed from the overflow (17) of the third hydrocyclone (6) and the clear effluent (23), which is an overflow from the thickener (8), is used for diluting in the suspension tank (3).
