Patent DE-4106930-A1 (DE)
Inventor: HAEUSLER FRANZ ULRICH DR ING
IPC: B63B71/20
Filed: 1991-03-05
Abstract: The method disclosed makes it possible to produce sheets of ice, in particular sheets for use in tests using models of ships or marine structures, the ice sheet having a texture (1235) which at least approximates that of a natural sheet of ice, and its deformation and failure characteristics reflect with substancial accuracy, on a reduced scale, the behaviour observed on ice sheets in nature. The method consists in producing an ice layer by disrupting the columnar growth (1230) of the ice by the introduction of finely particulate ice-growth nuclei (1202) into the water body in such a way that fine-grain ice (1260) is obtained through the whole thickness of the ice or in one or more layers.

Patent DE-4120277-A1 (DE)
Inventor: BRENTRUP LUDGER DR ING
IPC: B01D53/58
Filed: 1991-06-19
Abstract: In this process and apparatus, exhaust gases to be purified from oven installations are initially subjected to dust removal in a first filter stage and then purified in at least one further filter stage with the aid of a carbon-containing filter medium from the NHx compounds and/or volatile toxic elements and toxic compounds contained therein with at least partial NOx reduction. In order that the filter dust removed in the first filter stage can be either suitably reused or stored in simple waste tips without problem, the content of low-boiling toxic substances and toxic compounds in this separated filter dust is reduced by sequential process steps, the toxic substances mentioned being evaporated from the filter dust, the dust fractions being separated from these vapours and the vapours from which the dust has been removed being passed through a filter unit containing carbon-containing filter medium.

Title: Projection system for slides - has two projectors which can be rotated about their vertical axes
Inventor: HAEHNEL GUIDO DIPL ING
IPC: G03B21/13
Filed: 1991-07-24
Abstract: A projection system for slides can be changed immediately from a fade out projection to a panoramic projection and vice versa. The system consists of two projectors mounted side by side on a common base frame. Each projector is mounted on a support rotatable about a vertical axis relative to the base frame.

Patent DE-4213617-A1 (DE)
Inventor: BERGEMANN THOMAS
IPC: A01F15/07
Filed: 1992-04-27
Abstract: In the case of a baling press for forming essentially cylindrical bales made of cardboard waste, paper waste, film waste or a similar material, the material, which can be fed to a baling chamber, is made to rotate in the baling chamber by at least one drivable carrier belt which at least partly encloses the baling chamber parallel to the cylinder axis of the finished cylindrical bale. In this process, the material can be compacted by the carrier belt, which can be pressed against at least some parts of the material, to form a cylindrical bale, using at least one motor-drivable drive roller which is at least partly enclosed by one of the carrier belts. The carrier belt rests against the drive roller with its top side facing the cylindrical bale. The carrier belt, forming a wedge-shaped gap which is open at the top, is guided under tensile stress via deflection rollers in such a way that mutually opposing regions of the carrier belt recede to the essentially cylindrical baling chamber (56) when material is fed into the wedge-shaped gap, with widening of the gap. The carrier belt extends in the direction of the cylinder axis of the finished cylindrical bale over the entire width of the baling chamber. The baling chamber is surrounded by a single carrier belt. The angle of wrap of the carrier belt amounts on the drive roller to over 270 DEG , preferably over 300 DEG . <IMAGE>

Title: Monitoring device for detecting application of glue to carton - uses contactless capacitive sensor with probes either side of substrate, and determines product of measurement signal frequencies
Inventor: SAYER HEINZ DIPL ING
IPC: G01B7/06
Filed: 1992-05-29
Abstract: The substrate e.g. a carton or box (3) moves parallel to a contactless capacitive sensor arranged near the substrate surface with a pair of probes (10,20) opposite the surface. A 1/4-wavelength line with its open end formed by the probes is the frequency defining element of a high frequency oscillator circuit contg. the capacitance. Variations in frequency of the oscillator caused by relative motion of the sensor and substrate are detected. The probes lie on opposite sides of the substrate. The product (f1-f0)*(f2-f0) is used as the measurement signal, where f0 is the fundamental probe frequency without the substrate and f1 and f2 the probe frequencies with the substrate present. USE/ADVANTAGE - E.g. for determining the presence or absence of adhesive on cartons in a production line. The dependence of the measurement signal on the distance to the substrate is suppressed.

Title: Adjustable bearing, particularly for turbo sets
Inventor: BIRKE WERNER DR ING
IPC: F16C32/06
Filed: 1993-03-16
Abstract: The invention relates to a bearing arrangement of known construction with components of a spherically supported journal-bearing shell as used, in particular, for rotors of turbo machines. To match the spherically designed bearing shell (8a, 8b) to the respective position of the shaft journal, the bearing contains an integral hydraulic system which responds to specified limit temperatures in the bearing metal and brings about mechanical decoupling of the bearing shell (8a, 8b) without eliminating the preload on the bearing shell. For this purpose, hydraulic raising pockets (10) are arranged in the spherical insert (3) and spring-loaded pistons (6) are arranged in the bearing cap (5). After the raising of the bearing shell (8a, 8b) counter to the pressure of the spring-loaded pistons (6) and the formation of a corresponding lubricating film, a restoring moment which brings about the normal setting of the bearing shell (8a, 8b) relative to the position of the journal is brought about hydraulically by means of one of the pressure surfaces (12a or 12b) of the shaft-raising facility. <IMAGE>
