Title: Condensing apparatus for drawn sliver at a ring spinner has a clamping roller with a rotating surface speed faster than the rotary speed of the final pair of drawing rollers
Inventor: STAHLECKER HANS
IPC: D01H5/72
Filed: 1998-08-17
Abstract: The assembly to condense a drawn sliver, at a ring spinner, has a clamping roller (16) which rotates at a surface speed which is 3-8% faster than the surface speed of the final roller pair (2) at the drawing unit.  The drive for the clamping roller (16) is connected to the drive for at least one roller (6,7) in the final pair (2) of drawing rollers. A mesh belt (15) supports the drawn sliver (10) at the clamping roller (16), to carry the sliver through at the speed of the clamping roller (16) rotation, over a suction slit (19). The mesh belt (15) movement is applied by the clamping roller (16), or vice versa. The mesh belt (15) moves over a stationary sliding surface with the suction slit (19). The mesh belt (15) has a smoother side towards the sliding surface, which is curved in the direction of sliver travel. The clamping roller (16) is carried by the arm (23) which applies pressure to the rollers of the drawing unit (1).

Title: Cage like gripping instrument for endoscope
Inventor: OUCHI TERUO
IPC: A61B17/22
Filed: 1998-09-10
Abstract: The elastic wires forming the cage are twisted relative to the cage central axis and are guided into and out of a sleeve by specially provided surfaces at the sleeve opening. The cage structure (10) for gripping the endoscope is formed by three or more elastic wires (1) that are bundled together at two points, the cage being formed between these two points where they diverge and converge respectively. The wires are sufficiently elastic to enable them to pulled into a sleeve (30), at which point the cage structure disappears, and to allow them to be pulled out again to form the cage structure once more. The elastic wires are twisted in the same direction about the central axis of the cage structure. Guide surfaces (31) for the wires are provided at the tip end opening (30a) of the sleeve.

Title: Autonomous global positioning method using gyroscopic characteristics by comparing output of three orthogonal rotation rate sensors with components of maximum amplitude of rotation rate of earth
Inventor: BOEHM MANFRED
IPC: G01C21/16
Filed: 1998-11-14
Abstract: The method involves spatially aligning three mutually orthogonal rotation rate sensors so that one lies parallel to the plane of the ecliptic, the second lies in the plane in which the earth's axis of rotation lies, and the third lies in a plane orthogonal to the other two planes. The sensors are aligned by comparing the output signals with three preset signals obtained from the three components of the maximum amplitude of the rotation rate of the earth. The longitude and latitude on earth can then be calculated from the sensor angles w.r.t. a local plumb line vertical, using a precise time measure.

Filed: 1998-11-30
Abstract: The invention relates to a method for detecting a performance drop in components that are impinged upon with electric current or which can be brought into contact therewith in arc furnaces, whereby an electric arc is initially produced from an electrode during the operation of said furnaces. According to the invention, the blaze of the arc furnace is detected close to the furnace and the measuring data relating to the blaze is fed from the point of measurement to a measuring and regulating device that is disposed in a protected location where it is processed. Control signals are sent to an actuator if deviations occur from a predefinable value, whereby the actuator influences the operating mode of the arc furnace and, more particularly, interrupts the power supply. The invention also relates to a device for detecting the consumption and/or breakage of components that can be impinged upon by electric current or brought into contact therewith in arc furnaces that possess a furnace vessel that can be closed by means of a lid. According to the invention, measuring elements (41) for the detection of UV or infra-red light are provided. Said measuring elements (41) are connected to a measuring and regulating device (43) via measuring lines (42). The measuring and regulating device (43) is connected to the actuator (45) via control lines (44), whereby said actuator acts upon the operating mode of the arc furnace.
