Patent DE-2653342-A1 (DE)
Inventor: TUNBRA LARS-OLOF
IPC: E02D/
Filed: 1976-11-24
Abstract: A foundation pit (1) is provisionally excavated and a sealing layer (2), expediently a plastic mat, is introduced therein, one side of said mat provisionally projecting some way above the open foundation pit. After pouring in a layer (3) of ballast and sand, the tanks or oil tanks (4) are placed thereon. The tanks are then covered with a layer (5) of ballast and sand. Water is poured in on top of this until the water level (7) lies between the upper side of the tanks and the level (6) of the ballast and sand layer (5). The ballast and sand layer (5) is covered by means of that part of the plastic mat (2) projecting beyond the foundation-pit edge, and said plastic mat is sealed off at all joints. If one of the tanks then leaks, its contents, e.g. oil, since it is lighter than water, cannot escape; on the contrary, some of the water inside the sealing layer, which has been welded shut, penetrates into the tank. Lowering of the water level is shown in a water-level gauge pipe (10). Any escape of the contents from the tanks is thus avoided.   <IMAGE>

Title: Wind driven electricity generating station - has flywheel and hydraulic circuit to balance energy input with demand
Inventor: REGAR KARL-NIKOLAUS
IPC: F03D9/25
Filed: 1977-05-20
Abstract: The installation has a wing driven tubine (1) with a fixed ratio gear (2) to an output shaft (93). The shaft n3) provides an input through a free wheel (4) to an overall torque gear train (5). The gear train (5) drives an electrical generator (6) and also a flywheel (7) and also has two connections to hydraulic machines (8a, 8b) which can run as pumps or motors. They transfer fluid between pressure vessel containers (9a, 9b). When the wind provides more energy than the generator requires, the excess is used to drive the machines as motors and their output speeds up the flywheel. When there is insufficient wind energy available for the generator the flywheel drives the machines as pumps and adds energy to that obtained from the wind.

Title: IC engine selective valve interrupting system - has toothed sleeve acting against toothed thrust member to deactivate cam drive
Inventor: SPRINGER WILLI
IPC: F01L13/00
Filed: 1978-04-03
Abstract: The valve shut off for use in an I.C. engine renders some cylinders inoperative when the engine is at part load. A selectively operable mechanism is fitted between the camshaft and the valve stem. The mechanism acts either as a rigid body or a soft body absorbing the cam lift without operating the valve.

Title: Enlarged capacity diffusion column esp. for sugar beet - has additional feeders ensuring continuous cleaning of sieve bottom
Inventor: STRAUBE ELMAR
IPC: B01D11/02
Filed: 1978-06-10
Abstract: The parent patent describes a diffusion column for swilling out liquors, esp. the juice from sugar beet cuttings in countercurrent, formed by a vertical cylindrical tube in which a centre tube is positioned concentrically. The central tube carries a rotary cutting distributor beneath which a sieve bottom is cleaned constantly. A pump delivers the mash of beet cuttings through a channel to the distributor, the front edge of which is formed by a number of slide shoes resting on the sieve bottom. The central tube has, at its bottom end a plate, beneath which, there is, supported coaxially, a shaft journal in a bearing in the bottom housing. The improvements that the opening through which the shaft journal passes has two or more channels in the housing provided with guide plates. Each mash channel in the housing has a flanged connection, which for pref. is connected to the m ain mash feed pipeline by pipe bends, each of which offers the same resistance to the flow. The new arrangement ensures that behind each mash distributor the surface of the sieve is kept clear and the most efficient draining of the juice is achieved.

Filed: 1978-06-19
Abstract: A star wheel shaft (1) of the device has one clutch half (22) which can be disengaged and is intended to engage in a clutch half (21) which is connected to the pinion shaft (7) of a motor (6). A spring drum (17) has a toothed rim (23) for engaging with a pinion (16) on the pinion shaft (7). The spring drum (17) is supported such that it can rotate and is used for holding a spiral spring (26) having an inner end (27) and an outer end (28).

Title: Removal of solid impurities from detergent lubricating oil additives - by addn. of polar solvent and phase sepn.
Inventor: SPITSYN VIKTOR IVANOVITSCH
IPC: B03C5/02
Filed: 1978-08-26
Abstract: Mechanical impurities are removed from detergent additives for lubricating oils by phase sepn., after addn. of 0.025-10 wt.% polar liquid with dielectric constant >=17 to the additive soln. Solid particles of 0.5-5 mu m size resulting from synthesis of the additive, e.g. by neutralisation of sulphonic acid soln. in oil with Ca(OH)2. which are very difficult to separate, are reduced to below 500 mg/100 g. Prolonged centrifuging with sepn. factor 1000 and super-centrifuging: with sepn. factor 15000, are eliminated. The process causes coagulation of the particles, which increases their sedimentation rate around 1000 times.
