Patent AT-409739-B (AT)
IPC: G10D3/16
Filed: 1998-02-02
Granted: 2002-10-25
Abstract: A fibrous reinforcement and curable plastic are introduced into a mold (3,4) using a hollow and/or removable core (6). Internal pressure is applied by the core to press the resin-impregnated reinforcement (5) against the cavity wall and the plastic is then cured. An Independent claim is made for a hollow bow frame (1) with a tubular wall (7) of fiber-reinforced material. Preferred Features: The core (6) is a film tube or thin walled tube which is expanded by compressed air or heated pressurized fluid at 3-15 bar. A lance inserted through the hollow core acts as a support for the fiber reinforcement during placing in the mold cavity. In an alternative process method a wedge-shaped part carrying the fibrous material is moved forward inside the latter to compress it against the cavity wall. The fiber reinforced material can be a prepreg containing 30-50%, preferably 40% resin or is a separate fibrous reinforcement which is located in the mold before resin is introduced. An outer film is placed in the mold before the fiber reinforcement.

Title: Support structure for metal-jacketed suspended devices
Inventor: FERSCHA FRANZ DIPL ING DR
IPC: F22B37/24
Filed: 1995-10-16
Granted: 2003-05-26
Abstract: In a support structure for metal-jacketed suspended devices, such as for example waste heat boilers with horizontally arranged heating surfaces in tower construction, the suspended metal jacket is reinforced in the neighbourhood of its upper, particularly cold, end with a horizontal reinforcing ring through which supports (3) are passed and are mounted on stubs (4, 4') outside the metal jacket and thereby support the whole device. The reinforcing ring (2) is reinforced with respect to the metal jacket (1) and has at its upper and lower ends curved, particularly semicircular, flanges (6). The novel support structure is particularly advantageous for waste heat boilers in twin construction, since here the support between individual metal jackets can be formed as a fixed point, so that the structure can freely rotate outwards.<IMAGE>

Abstract: A drying apparatus for sheets of material. The apparatus includes a drying chamber through which a sheet of material which is to be dried is conveyed, and in which the sheet of material is contacted by flowing drying gas. The apparatus also includes a feed line for supplying drying gas to the apparatus, a heater for heating the drying gas, and a withdrawal line for withdrawing the drying gas from the apparatus. The drying chamber includes cup-shaped and rounded-off wall elements which are easily detachably connected to one another. The wall elements have a smooth inner surface. A jacket is disposed around the drying chamber. An intermediate space is defined between the inner surface of the jacket and the outer surface of the wall elements of the drying chamber. Drying gas is introduced through the feed line into the intermediate space. After this drying gas has been heated in the heater, it flows through the drying chamber. A pressure gradient is maintained between the intermediate space, the drying space, and the atmosphere, with the pressure being lowest in said drying chamber means. The hot drying gas in the drying chamber gives off at least some of its heat to the drying gas in the intermediate space. The used drying gas leaves the drying chamber via the withdrawal line.

Abstract: The rolling apparatus contains a controlled deflection roll and, in order to improve uniformity of the roll nip or gap or to more precisely maintain a desired rolling profile, a counter roll contains a journal-less tubular roll or shell which is articulatedly supported at a support beam or at supports of a roll stand. The support distance of the counter roll at the most is equal to the effective support distance in the controlled deflection roll. The bending lines of the controlled deflection roll and of the counter roll thus can be matched in an improved manner.

The quantizing of the sample values in the sub-bands, e.g. 24 sub-bands, is controlled to the extent that the quantizing noise levels of the individual sub-band signals are at approximately the same level difference from the masking threshold of the human auditory system resulting from the individual sub-band signals. The differences of the quantizing noise levels of the sub-band signals with respect to the resulting masking threshold are set by the difference between the total information flow required for coding and the total information flow available for coding. The available total information flow is set and may then fluctuate as a function of the signal.

Abstract: The transport apparatus comprises an endless guide device extending in a closed path and at which there are guided a number of entrainment elements. These entrainment elements are interconnected by a toothed belt deformed into a substantially wave-shaped configuration by attachment elements secured at the entrainment elements. At each of the starting region and terminal region of the conveying-active path of the transport apparatus, there are rotatably mounted two parallel cam discs rotatable in a predetermined direction of rotation by related drives. Recesses in the cam discs act upon the entrainment elements such that the latter are driven at the starting region and terminal region of the conveying-active path and are dispositioned in a predetermined mutual position. The spacing between the entrainment elements at the conveying-active path and at the non-conveying active path is compensated by the resilient action of the wave-shaped deformed toothed belt. Differences in the operating cadence or in the phase position between printed products delivered to the transport apparatus and outfed away therefrom are compensated by increasing or reducing the spacing between the entrainment elements.
