Abstract: Nonwoven web comprising thermoplastic meltblown fibers or filaments predominantly present as agglomerates (32) or multiple fused fiber areas (34). Such agglomerates (32) in the web act as columns and impart a desired degree of strength and resistance to compaction. In contrast to prior art webs where such agglomerates have been considered undesirable, the webs of the present invention find particular utility when formed into cylinders as filter plugs for smoking articles. In smoking articles of the invention, the filter plugs have a desired pressure drop while demonstrating an unexpected degree of firmness, all at an economically attractive cost. Preferred embodiments include those where the machine direction strength to cross machine direction grab tensile ratios in the range of from about 1:1 to 4:1 and the fibers or filaments are made from polypropylene. Other embodiments include webs and filter plugs containing additives distributed throughout the web.

Abstract: A new process of synthesis of optically active  alpha -amino acids is described through nitrosation in a non-aqueous, aprotic system, of the corresponding N-carbamyl derivatives followed by decomposition of the thus obtained N-nitroso derivatives in aqueous acidic medium. The process, which is of a general applicability, leads to a remarkable increase in the reaction yields, due to the suppression of the main side reaction leading to the corresponding  alpha -hydroxy-acid. Some N-nitroso intermediates, which can be recovered from the process of the invention, are also described.

Title: Aircraft ground-handling vehicle with a hold-back device
IPC: B64F1/22
Filed: 1988-08-12
Granted: 1992-05-27
Abstract: In order to receive the nose wheel of an aircraft, an aircraft ground-handling vehicle has a U-shaped chassis and a lifting and clamping device arranged in the U-recess and consisting of a run-up ramp, a stop, a support plate pushing the nose wheel onto the run-up ramp against the stop, and a hold-down guided movably above the run-up ramp. In the initial position, the hold-down has a ground clearance which is smaller than the diameter of the smallest nose wheel under consideration, is applied at the start of the receiving process to the nose wheel circumference in the forward upper quadrant thereof, follows the nose wheel during its receiving movement, and after termination of the receiving process is pressed against the nose wheel with a defined hold-down force by means of a hydraulic hold-down cylinder. A pressure sensor can detect a fall in the hold-down pressure in the hold-down cylinder and trigger a corresponding alarm signal.

Abstract: The covering element (2) for a chimney serves to cover the chimney head of chimneys which are brick-lined or made of chimney elements. In order to avoid cold bridges and the associated extremely disadvantageous condensate formation in the waste gas outlet region of the chimney, the covering element (2) has a heat-insulating part (3) consisting of heat-insulating material, which covers the upwardly directed end face of the chimney head. This heat-insulating part (3) is surrounded on its upper, inner and outer side (4, 5, 6) by a water- impervious covering (7) and extends from the outside of the expansion joint sleeve (10) as far as over the outer edge of the chimney. The expansion joint sleeve (10) is rigidly connected in a thermally insulated manner, via a practically non-heat-conducting silicone rubber layer (28), to the downwardly directed surface of the upper side (4) of the covering (7). The underside of the heat-insulating material (3) is supported by a copper net (8) or a number of copper bands and thus brushed over, over practically its entire surface, by the circulation air which flows through the rear ventilation ducts (13) and escapes into the open behind the drip sheet (9). <IMAGE>
