Patent EP-0335190-A2 (EP)
Inventor: LANGE KLAUS-ULRICH
IPC: B41F13/62
Filed: 1989-03-16
Abstract: To change over from collect run to straight run production it is necessary, independent of the drive, for the driven cover discs which control the movement of the perforating needle or the folding knife via roller levers to be rotated relative to the fixed-position radial cams which, together with the cover discs, form the control contours. As distinct from the previous customary rotation by hand involving an in-and-out motion of a bolt coupling by means of a hand-wheel, a change-over is made possible from a central control desk, dispensing with a coupling. 
<??>A perforating cam-plate cover disc (61) and a folding knife cam-plate cover disc (62) are driven via a hollow pinion gear (29) mounted so as to be axially displaceable on a shaft (26) partly constructed as a helical screw (28) and engaging with a gear wheel (20) for the drive of the folding and collection cylinder (9), a hollow cylindrical attachment (31) connected to the pinion gear, and arranged radially in roller bolts (36, 37) in the attachment, the roller flanks of the roller bolts being in flank contact with those of the helical screw (28). Independently of the drive train, an axial displacement of the hollow pinion gear (29) results in a rotation of the cover discs (61, 62) relative to the fixed radial cams (25, 23).

Filed: 1989-04-03
Abstract: The invention provides that coloured yarn poms colour coded according to a six digit coding and are arranged in a particular manner to enable colour selection for carpets to be performed by designers, architects and the like without actually examining a sample carpet or a portion of carpet. The colour poms are arranged in groups of which one pom defines the base colour, and the remaining poms in that group are shaded poms, tint poms and tone poms. The triangular layout provides that the base colour bunch is at the apex (30) of a right angled triangle with the shades extending down one of the smaller sides (20) of the tiangle and the tints extending down the other side (22) with the tones lying between the shades and the tints. The triangle is a 45o/right angled triangle. Each pom preferably comprises a plurality of appropriately coloured yarns held by a sleeve so that the yarn ends spread mushroom fashion from one end of the sleeve and a second sleeve can be slid over the first sleeve to compress the spread ends into a flat surface which can be presented to a spectrophotometer for identifying the colour density in the said flat face.

Abstract: Described are ways of improving the yields of specification grade polyimide foam on a consistent basis from one run to the next, by use of improved microwave-­based foaming processes. In one such process, during the application of the microwave radiation, the body of polyimide precursor and of the foam structure as it is developing therefrom are maintained under a substantially vapor-impermeable microwave-compatible shroud that does not substantially restrict or impede development of the foam structure; and the microwave radiation is directed upon the top, sides and ends of the body of polyimide precursor and of the foam structure as it is developing, but the extent to which such radiation impinges upwardly into the bottom of said body and said foam structure is curtailed, preferably by means of a metallic shield located below the precursor and developing foam struc­ture. Mechanisms by which the shields and shrouds function to provide the improvements of the process are discussed, and methods based thereon are set forth.

Abstract: A system providing a guess mechanism for improving the speed of translating effective addresses produced by a processor to real addresses in memory is disclosed wherein a set of Lookaside Tables ( TLB(0) and TLB(I) ) and logic elements are used along with a set of validity registers and an MRU register (40) to guess at the appropriate real frame index from one of the Tables to be output in the real address in the first cycle of a two cycle operation. The low order bits of the effective address are sent to index the Tables during the first cycle and the high order bits are used during the second cycle for comparison with the set of Table entries selected in the first cycle as containing the real frame index that is output. The selection of the actual real frame index that is output involves a guess using the validity and MRU registers (40) along with indexing of the Tables by a portion of the low order bits. If the logic indicates, upon comparison of 1) the Table entry containing the real frame index that is output during the first cycle with 2) the high order bit comparison of the second cycle, that the selected real frame index was inappropriate, a signal is sent after the second cycle to invalidate the output of the real address incorporating that real frame index.

Abstract: An acceleration sensor having a sensing mass supported relative to a frame by a plurality of beams having a plurality of resistors integral therewith. The resistance of the beam resistors varies as the sensing mass is displaced relative to the frame in response to acceleration of the frame in a direction generally normal to the plane of beam extension. The displacement of the sensing mass due to such acceleration produces a corresponding change in the output of a Wheatstone bridge incorporating the beam resistors in the legs thereof. At least one leg of the bridge additionally has a resistor of variable resistance in series with the beam resistor thereof, the resistance of which is controlled by a microprocessor, whereby the bridge output is adjusted to compensate for temperature effects and manufacturing tolerances. The output of the electrical control circuit for the sensor is periodically calibrated by electrostatically deflecting the sensing mass relative to the frame, whereby the sensing mass is subjected to the equivalent of a known accelerating field, and using the resultant change in bridge output as a reference value for calibrating the instantaneous changes in bridge output resulting from the acceleration of the sensor frame.

Abstract: The method of surface-treating dry-powdered phosphor particles for use in manufacturing a luminescent viewing screen (22) for a CRT (10), to control triboelectric charge characteristics of the phosphor particles, includes the steps of dissolving a suitable quantity of a polymeric coupling agent in a suitable solvent to form a mixture, surface-treating the phosphor particles by adding them to the mixture to provide a coating of the coupling agent thereon, and then drying the surface-treated phosphor particles. The resultant dry-powdered surface-treated phosphor particles are used to make the screen. The coupling agent controls the triboelectric charge characteristics of the phosphor particles during the electrophotographic manufacturing of the screen.

Abstract: The invention is directed to a method and apparatus for selectively and simultaneously drilling a plurality of holes in thin panels such as printed circuit boards, while providing for automatic changing of the drill bits, individually or plurally, as required. A tray of drill bits (42) is driveable in X and a row of vacuum pickers (20) are driveable in Y, so that the various bit locations of the tray (42) are addressable by such X-Y positioning, and selectable vacuum pickers (20, 34) are extensible and retractable so as to pick and place the drill bits (74) at various matrix locations of the tray (42). The vacuum pickers (20, 34) also are extensible and retractable through corresponding tray openings (48) in order to deliver replacement bits (74) to, and retrieve used bits from, a flipper assembly (111) associated with each drilling module (50). Each flipper assembly (111) transfers bits back and forth between the vacuum picker and drill without having to transfer either bit through the opening in a footprint portion of the pressure foot (90) which engages the materials to be drilled during the drilling operation. Thus, the footprint opening may be made smaller in diameter than depth stop collars or the like which are of greater diameter than the working portion of the bit which is advanced through the footprint opening during drilling. This smaller footprint opening of the pressure foot is for minimizing or eliminating hole "smears" and for overcoming problems normally associated with the so-called "oil can effect".

Abstract: The application of brake pressure to limit the spin of a driven wheel in a traction control method is made adaptive to the torque demand on the engine. This is accomplished by increasing the brake pressure when an excessive spin condition is sensed at a rate that is proportional to a parameter related to engine torque. The ramp is then terminated when the wheel parameters attain certain predetermined conditions. The brake pressure ramp is terminated when the wheel jerk is negative while at the same time the wheel deceleration is below a predetermined value. After the ramp is terminated, the brake pressure of the spinning wheel (10,12) is controlled based on wheel parameters such as wheel spin ratio or the difference between the speed of the spinning wheel and vehicle speed.
