Abstract: The invention relates to an elevating platform for surmounting a difference in level of conveyor tracks for transport devices such as skids or the like. The elevating platform consists of a support frame (1) and a lifting frame (18) which is mounted in a vertically movable manner on the support frame (1) and which can be lifted and lowered by a lifting arrangement via eccentrically mounted lifting members (20). Here, the lifting members (20) are driven together in a rotary manner by a drive (12), fixed to the support, via endless power-transmission elements (15, 16) and are thus vertically adjusted relative to the support frame. In order to permit simple exchange of the endless power-transmission elements (15, 16) without considerable dismantling effort or severing of the transmission elements, provision is made for the power-transmission elements - as viewed in plan view of the lifting platform - to be arranged so as to lie outside the support frame (1).   <IMAGE>

Abstract: An operation microscope having a fixed principle objective (3) for at least two surgeons is described, in which at least one of the stereoscopic observing beam paths (1) is constructed to be individually focusable. Lens systems (6, 7; 15, 16) for varying the imaging scale are arranged in the observing beam paths (1; 2). The individually focusable beam path contains pairs (4, 5) of rotating wedges for adjusting the object plane. Furthermore, modularly constructed pupil displacement systems (63, 67) are described which have different mechanical design lengths in conjunction with the same optical paths. 
<??>The operation microscope can be configured individually owing to the modular construction of the individual function or system units, and can thus be adapted to the particular operation disciplines.

Title: Dual tread tire
Inventor: VEITH ALAN G
IPC: B60C9/08
Filed: 1991-05-03
Abstract: A tire (20) having a longitudinal central axis (A) about which the tire is rotatable. The tire includes a pair of axially spaced rim beads (62,64). A carcass extends between and is connected at opposite ends to the rim beads. Each of a pair of axially spaced ground engaging tread portions (24) includes an annular reinforcing member having substantially inextensible and parallel extending cords disposed at an acute angle relative to the mid-circumferential plane of the tire. The cords in the annular reinforcing member in one of the pair of tread portions extend in an opposite direction to the cords in the annular reinforcing member in the other of the pair of tread portions to minimize ply steer. A central portion is located intermediate the pair of tread portions and includes a surface defining a circumferentially extending groove. A central member has a substantially annular configuration in an unloaded condition. The central member has an outer diameter (R3 + R4) greater than the outer diameter of either of the rim beads (D2) and less than the inner diameter (2 R5) of the annular reinforcing member. The central member is located radially inward of the groove in the central portion and is deflectable from the annular configuration as the tire rotates through a footprint.

Abstract: The connection device for low current installations, particularly for telecommunication and data communication, comprises a multiway socket (1) whose contact pins (2) are arranged in a predetermined basic module, and a plug (3), which interacts with the socket, there being provided between the socket and plug coding means which, in the case of non-correspondence, prevent the plug and socket being plugged together to connect the contacts. These coding means consist of a component, especially a sleeve-shaped insert (6), which changes the geometrical cross-section of the plug opening (4) of the socket (1) in accordance with the cross-section of the insertion part (5) of the plug (3) to be used. Such sleeve-shaped components permit matching of the plug opening of the socket to any conceivable geometrical cross-section of the insertion part of the plug to be used, as a result of which virtually unlimited coding possibilities are provided with very simple components and very simple handling. <IMAGE>

Abstract: An electrical terminal for mounting on a circuit board, comprises a metal post having a portion (113) of increased width which has been split longitudinally to form two limbs (115,115'). The limbs (115,115') have been pushed relatively away from each other parallel to the plane of the slit to lie in adjacent parallel planes and have been subsequently pushed towards each other across the plane of the slit to bring portions (116,116') of their oppositely facing rolled surfaces adjacent to the slit, into partially overlapping face-to-face engagement, so that remote edge portions (118,118') of the limbs (115,115') are engaged with the wall of a through hole in the circuit board during insertion thereinto. The limbs (115,115') are thereby forced further together with progressive sliding engagement of the rolled surface portions (116,116') across each other further into overlapping engagement.

Abstract: A hood (300) for making a metal oxide coating on glass articles (103) constitutes a tunnel through which the articles (103) pass along a conveyor. Gas carrying the coating chemical is blown/sucked across the conveyor path from blowing and suction channels (301,302) opposed on opposite sides of the conveyor. To reduce the operational temperatures of sidewall surfaces of the hood on the coating region, the sidewalls are made from tapered segments so that only line edges (312) face onto the conveyor path. Reduced temperature of the sidewall surfaces (314) reduces the formation of deposits thereon in operation.

En section, le rapport entre le noyau et la gaine est compris entre 1/1 et 100/1, et ledit noyau présente une périphérie lisse s'étendant de manière uniforme dans le sens de l'axe de la fibre, tandis que la gaine enrobant le noyau présente une surface rugueuse dans laquelle sont formées de nombreuses nervures dans le sens circonférentiel et à proximité de l'axe de la fibre. On peut aisément produire ledit filament par un filage direct à chaud des constituants noyau et gaine dans le rapport précité, puis par l'étirage jusqu'à une longueur de 1,1 à 10,0 fois supérieure à l'originelle, et ci-après par la relaxation. Le filament présente d'excellentes propriétés élastiques, un faible coefficient de friction superficielle, et un aspect sans brillant dû à la réflection diffuse de la lumière par ladite surface rugueuse. Il est également agréable à porter lorsqu'il est réalisé comme une structure fibreuse telle que des bas pour femmes.

Abstract: A test pattern generation device for producing a test pattern signals for testing a preselected digital circuit includes a dominant pattern signal generator (11) and a subservient pattern signal generator (6). When a first dominant pattern signal (0,0,0,0,0) is generated, five subservient pattern signals (1,0,0,0,0), (0,1,0,0,0), (0,0,1,0,0), (0,0,0,1,0) and (0,0,0,0,1) are generated, each being unit Hamming distance from the dominant pattern signal. The subservient pattern signals are sequentially applied to a simulator (4) carrying a hypothetical digital circuit for producing a controllability cost CC0 f  and a continuous cyclic logic value CV f  at a preselected line G f  in the digital circuit for each subservient pattern signal. A cost generator (9) produces an evaluation cost CT f  by the use of the controllability cost CC0 f  and the continuous cyclic logic value CV f  for each subservient pattern signal. A selector (10) selects from the set of subservient pattern signals a subservient pattern signal that produced a minimum evaluation cost CT f , test pattern memory (11) stores the selected subservient pattern signal as one test pattern and assigning the selected subservient pattern signal as a next dominant pattern signal in a next cycle operation.
