Abstract: A sound pressure level calibrator, which is suitable for sound pressures to be measured in excess of 124 dB and which can be adapted to the installed sound pressure level sensor. This object is attained by a sound pressure level calibrator comprising a pistonphone and a high-pressure adapter connected to the output of the pistonphone. The high-pressure adapter acts as a resonator. With an expanded adapter opening the high-pressure adapter is connected in soundproof manner with the sound pressure level sensor, which is inserted into a structure. The invention can be used for a sound pressure level calibrator to calibrate a sound pressure level sensor, which is integrated into a structure.

Abstract: A movement prevention device for a vehicle door latch mechanism includes a body movable between blocking and non-blocking positions in response to sudden changes in inertia on the vehicle, such as during a side impact crash. The device interferes with movement of the handle to prevent unintended opening of the latch mechanism.

Abstract: The present invention relates to kinase inhibitor compounds and derivatives thereof as well as compositions comprising them for the treatment of neurological disorders such as Alzheimers' disease, Parkinsons' disease, obesity, hypertension and the like. These pyridazinone derivatives particularly inhibit the metabolic activity of glycogen synthase kinase —3? (GSK-3?) which is believed to cause the neurodegeneration that results in these diseases.

Abstract: An inner actuator for automobile doors includes a lever-like handle adapted to be pivoted about an axis within a housing which is attached to the door, a linkage or an actuating cable which is led to a door lock and engages the handle, a spring which biases the handle into a rest position, a damper which is connected to a portion of the handle such that the movement of the handle into the rest position is damped, whereby a linear damper is provided which is linked to the door with one end and to a portion of the handle with the other end.

Abstract: Processes for determining whether a test substance contains lipases or lipase inhibitors are provided. Processes for determining the activity of lipases or lipase inhibitors are also provided. Furthermore, processes for the preparation of micelle or vesicle substrates comprising monoacylglyceride having a fluorescent label are described.

Abstract: In order to provide a walk-on platform arrangement, comprising at least one first sub-platform, which is movable from a rest position in a direction of extension into a working position, and a second sub-platform, which in the working position is disposed behind the first sub-platform, wherein a rear boundary edge of the first sub-platform and a front boundary edge of the second sub-platform in the rest position are spaced vertically apart from one another, with which platform arrangement the risk of accident for an operative walking on the platform arrangement in the working position is reduced, it is proposed that the platform arrangement comprises a guide system, by means of which the relative motion between the first sub-platform and the second sub-platform as the first sub-platform moves into the working position is guided in such a way that the vertical distance between the rear boundary edge of the first sub-platform and the front boundary edge of the second sub-platform in the working position is smal

Abstract: An air damper for a movably supported structural part in automobiles comprises a hollow cylinder closed at one end thereof, a closure cap mounted on the other end of the cylinder, a piston slidably guided within the cylinder, an annular recess at the circumference of the piston, and an annular sealing ring in the recess. The block-like sealing ring is made of a thermoplastic elastomer coated with a layer which has the same static and sliding frictions with the inner wall of the cylinder and the bottom of the recess. A coil spring is placed between the closure cap and the piston. A piston rod of the piston has an elongated rib contacting the spring when the spring is in a relieved state.

Abstract: An adaptive flow body is provided whose profile can be adapted to different operating requirements regarding lift and crosswinds, flow resistance, and steering. The rear part of the flow body is divided into two rear partial profiles by a slot that penetrates from the trailing edge toward the middle part in the lengthwise direction of the flow body profile. These rear partial profiles each also have a flexible inner skin and flexible outer skins fastened continuously on the middle part. An actuator with pushing or pulling movements acts on each inner skin, which movements are transmitted by joints from the inner skin to internal structural elements which transmit these movements through rigid connections as bending moments to the outer skin.

Abstract: A process for the preparation of dehydrated base products for thickened soups and sauces which disperse readily in hot water and form thick, creamy, lump-free products. The product is prepared by combining a starchy material with an edible fat into a homogeneous mixture. Water is added to the mixture which may also contain milk proteins. The mixture is then subjected to heat treatment, cooled and grated. Optionally the homogeneous mixture is heated under elevated pressure.

Abstract: The pocket structure for a foldable wing of an aircraft, especially a high erformance aircraft, is constructed at least partially of flexible material forming a completely closed volume with an inward fold for receiving a wing portion. The fold divides the closed volume into two portions which are interconnected outside the reach of the fold to form an auxiliary fuel tank for the aircraft. The pocket structure has sealing lips extending along both of its outwardly facing side walls. The sealing lips are constructed as two bellows which are filled with a gas under pressure. Thus, the lips perform two functions. First, the lips seal a zone below the wing from a zone on top of the wing to maintain the pressure difference. Second, the lips strengthen and protect the outwardly facing side walls of the wing pocket structure forming an auxiliary fuel tank. The pocket also performs two functions, namely, the wing receiving function and the tank function.

Abstract: An arrangement for the treatment of high-polymer articles with boiling acrylic acid or solutions thereof, particulary for use in the grafting of acrylic acid to previously irradiated high-polymer articles such as textiles and the like, has a vessel for accommodating an acrylic acid-containing bath. The arrangement further comprises at least one member which is provided with a copper surface, and the member is arranged in such a fashion that the copper surface is exposed to the interior of the vessel. The copper surface is free of direct contact with all metallic parts of the arrangement having a substantially different composition than this surface and, advantageously, this is effected by electrically insulating the copper surface or the member from the remainder of the arrangement. The insulation of the copper surface or the member from the metallic parts of the arrangement prevents corrosion effects which might occur by virtue of contact between dissimilar metals.
