Patent DE-4141890-A1 (DE)
Title: Eye cornea laser beam treating appts. - corrects for non-uniform gauss distribution of beam in Y-axis using microprocessor control
Inventor: SUMIYA TOSHIFUMI
IPC: B23K26/00
Filed: 1991-12-18
Abstract: The laser beam device consists of a laser beam source (10), flat mirrors (11, 12, 15) for deflecting the beam, on opening (13) with changeable diameter located between mirrors (12, 15) and a projection objective lens (14) for projecting the beam onto the cornea (16) via mirror (15). The lens (14) is in a conjugate position with respect to the opening (13) and cornea (16) and by moving the mirror (12) in the 2-direction the beam is forced to move from one end of the opening to the other thereby moving its Gauss distribution shape across the opening. USE/ADVANTAGE - Non-uniform distribution in laser beams with uniform distribution in X-axis and non-uniform distribution in Y-axis of the beam in Y-axis is taken account of and by pulsing cornea with beam in various positions across opening (13) for more uniform irradiation of cornea.

Title: Separable pipe serving as nuclear fuel element coolant channel - esp. for heavy water reactors, permits pipe exchange without reactor shut=down
Inventor: REIMER GERD DIPL ING
IPC: G21C15/06
Filed: 1991-12-19
Abstract: The separable pipe device (1) consists of three parts (5, 6, 7) with the first pipe part (5) attached, detachably, to the fuel element (10), and forms a coolant channel between the steam-water coolant (8) at the base of the reactor core and its collection at the top (9) of the reactor core. In the region between the moderator (4) and the coolant (8), the second pipe part (6) is provided with a closing device to prevent the flow of coolant as necessary. USE/ADVANTAGE - The device enables removal of the main separable pipe part (5) of the separable pipe device (1) during running of the reactor. This is necessary because the pipes properties are altered by radiation and hydrogen reduction. The advantage is that, with the claimed discovery, reactor shutdown is not necessary, with the corresponding time and economy savings.

Title: Passive gas compression and release machine e.g. for well-shaft type power station - has tubes on vertical chain drive within water-filled well collecting gas above water and releasing at BDC
Inventor: FRICKE RUDI
IPC: F03B17/02
Filed: 1992-01-23
Abstract: A passively acting machine for guaranteeing a constant and continuous supply of compressed gas to a load point consists of a deep water-filled well with watertight walls and a pressure lid. Inside is a vertical chain drive. On the chain is a series of compression pipes (closed at one end) which in turn swallow an amount of compressed gas delivered at the top of the well above the water level. The chain drives the pipes to the bottom of the well where the mouths are subject to extra water pressure. Beyond the BDC of the chain drive, the pipes are reversed so that the mouths point upwards and the compressed gas escapes into a funnel and supply pipe to the load point. ADVANTAGE - Increased efficiency and constant gas supply compared with previous similar devices.

Title: Multiple-shaft IC engine - has intermeshing shaft pairs, one for fuel intake and compression, other for expansion and exhaust
Inventor: STRAUS ERNST DR
IPC: F01C11/00
Filed: 1992-04-14
Abstract: A rotary piston engine similar to Wankel engine uses at least two intermeshing shafts for intake, compression, expansion and exhaust of a fuel to generate rotary energy. The principle is that of the Roots blower. The shafts have different dimensions or are discontinuous for optimum compression and expansion. One spindle pair is used for intake and compression of the fuel and another for the expansion of the ignited fuel followed by exhaust. A rotary slide valve connects the fuel chambers. The valves are all self regulating using the compression and expansion pressure. The intake/exhaust valve timing is speed-dependent as is the ignition timing. ADVANTAGE Increased engine efficiency and reduced toxic emissions.

Abstract: The sack breaker has a horizontally swivelling cutter (24) . It is controlled by the electronic scales (16) or by the  belt control scales so that when the actual weight of the filled sack is measured and differs from the ideal weight it breaks the wall of the sack. The filling and sack are then separated off through the mechanical sack trap (14) set in front of a further discharge conveyor belt. The sack breaker is installed directly in front of the mechanical sack trap so that the destroyed sack need only be moved over the shortest possible distance. ADVANTAGE - Compact design.

Title: Method and apparatus for reconstructing an underground pipeline
Inventor: GEISS DIETER
IPC: E21B7/28
Filed: 1993-03-19
Abstract: A pig (2) is moved through the pipeline (1) to be reconstructed. The breaking device (4) of the pig (2) exerts radial forces, acting from the outside and inside, on the pipeline.

Title: Apparatus for sealing components with an impregnating compound
Inventor: TERHARDT JOSEF
IPC: B29C35/08
Filed: 1993-03-19
Abstract: A description is given of a process (and an apparatus for carrying out the process) for sealing in each case a plurality of components, such as line transformers, with an impregnating compound which does not set at room temperature but at elevated temperature (for example 60 DEG  to 80 DEG C) sets within a short time, for example less than 30 minutes. The process comprises the process steps of introducing a pallet of components into a casting chamber (10) to which a vacuum can be applied, evacuating the casting chamber, sealing the components with the compound under vacuum (48), admitting air into the casting space (48), and moving out the components, preferably placed on a pallet (46), and moving the same into a multichambered oven (60), within which the component is subjected at above-atmospheric pressure to an elevated temperature, at which the impregnating compound sets. To save heating energy and pressure-applying energy, the oven has a lock-prechamber, a main chamber and a lock-postchamber, pressure constantly prevailing in the main chamber, while the lock chambers can be alternately pressurised and vented (Fig. 1). <IMAGE>
