Patent EP-0424277-A1 (EP)
Inventor: BLANCHARD PAUL
IPC: C22C19/05
Filed: 1990-10-19
Abstract: Process for improving the pitting and crevice corrosion resistance of a nickel-based alloy and also the alloy thus improved. Such an alloy contains at least 50% Ni and approximately 20% Cr, 4% Nb, 1% Ti and Al. According to the invention, when the alloy is being produced, the proportions of carbon and silicon are regulated within narrow limits which make it possible, when the metal solidifies, to avoid the formation by segregation of carbides of M6C type, the proportion by weight of carbon being maintained at at least 0.03% without exceeding 0.05%, and the proportion by weight of silicon not exceeding 0.15%, the absence of carbides containing silicon being verified in the raw casting state. The invention applies especially to the alloys employed for the production of ingots or of cast pieces of large size.

Title: Exhaust outlet with venturi
Inventor: DEVILLE PAUL
IPC: F01N13/20
Filed: 1990-12-13
Abstract: The exhaust outlet according to the invention comprises an upstream section (18) in the shape of a venturi, limited by convergent upstream walls (16) having an open angle and connecting, in a narrowed section (15), with divergent downstream walls (17) having a more reduced angle, and a downstream cylindrical portion (3) continuously connected to the downstream walls (17) of the upstream portion (18). The presence of the upstream portion (18) in the shape of a venturi allows a substantial reduction in exhaust noise without significantly affecting the power available from the engine.

Abstract: This device has a separate tilting device (17) and a lifting device which can be actuated independently therefrom. The tilting device (17) is essentially formed by a pivot frame (5) which is pivotably guided on the tilting side on a pair of horizontally extending guide tracks (10) and on the lifting side on two vertically extending lifting pillars (13). The vehicle body (1) is attached rigidly and with spacing on this pivot frame (5) which is designed to be as flat as possible. In order to raise this tilting device (17) two scissor-type lifting elements (18) are provided underneath it. The entire arrangement is attached to a rectangular, plane, accessible platform (20) for independently raising and lowering or tilting the vehicle body (1), said platform projecting - in its base outline - beyond the vehicle body (1) by the width of one working aisle.

Abstract: The invention relates to a document shredder (1) with two rotating cutter shafts (3) arranged parallel with one another and driven by way of gears (2), which shafts each have a plurality of cutter blades (5) axially arranged in rows and intermeshing with one another, which are held in pairs against each other, that is in cutting contact, by a force acting in an axial direction on their cutting flanks (13), the gears (2) being fixed on the cutter shafts (3) in an axial direction and provided with helical toothing (4). As a result of this the force component generated on the helical toothing (4), which is a function of the load and acts in an axial direction, holds the cutting flanks (13) of the cutter discs (5) in cutting contact and relieves the cutting flanks (13) or separates them from one another when the cutting device (1) is reversed. This is achieved extremely cost-effectively without additional components.

Abstract: The hydraulically impulsed wrench has a rotationally driven impact mechanism with an output shaft (23) for a screwing tool. The output shaft (23) possesses lamellae (33 to 36) which are distributed at angular distances of 90 DEG  over the circumference, are adjustable approximately radially outwards and, in the case of a 360 DEG -rotation of the output shaft (23), bear, in one position, sealingly on sealing strips (54, 55) of the impact-mechanism housing (5). Two diametrically opposite lamellae (33, 34) have follower members, through which they are adjustable in a positively controlled manner in cooperation with control paths (46, 48). Owing to the positive control of these lamellae (33, 34), the sealing strips (54, 55) can be simply manufactured. All of the lamellae (33 to 36) can additionally be arranged symmetrically to the axis of the output shaft (23), so that the output shaft (23) and their bearing points are not unevenly loaded on generating the angular momentum. <IMAGE>

Filed: 1991-09-13
Abstract: The invention is based on a deformable seal for the gap between the edge of an opening in a building and the tail of a vehicle drawn up to said opening, in which a deformable apron which rests against the vehicle is provided at a distance from the building and a roof awning (7) leading to the building is arranged above the apron, said awning protruding at both sides beyond the seal and hanging down freely there. To ensure that the apron and the supporting bodies (10) bearing it are sufficiently deformable when a vehicle comes into contact with them, the invention proposes that the lateral overhang (8) of the roof awning be weighted down at the edge by, for example, inserting a bar (13), e.g. a steel bar, into an edge loop (11).

The flow cross-sections of the chimneys (7) are further narrowed as against their relatively narrow entry cross-sections. 
<??>By means of this measure, on the one hand a uniform gas distribution is achieved as a consequence of a static gas pressure, and on the other hand gas and liquid are substantially conducted separately on flowing through the intermediate space between the sections (2a and 2b), a relatively high gas velocity being attained. This substantial separation of their flow paths improves, particularly in countercurrent columns having a flow parameter phi > 0.1, the stability of gas flow and liquid flow and thus also the efficiency of the countercurrent column.
