Abstract: A coating apparatus (10) for use in a sheet-fed or web-fed, offset rotary or flexographic printing press (12) to apply a protective and/or decorative coating to the surface of freshly printed sheets (18) includes a doctor blade coating unit (60) coupled to a pickup roller (68) for supplying liquid material from a remote supply drum (102) to sheets transported on the surface of a transfer/delivery cylinder (42) mounted on a press delivery drive shaft (54). Liquid material is circulated through the reservoir (66) of the doctor blade unit by suction flow produced by a return pump (112). This prevents the buildup of positive pressure within the doctor blade reservoir (66). The doctor blade reservoir is maintained at below ambient pressure level, thereby inhibiting leakage through the end seals. A vacuum sensor assembly (122, 128) provides a visual indication of air vacuum pressure in the doctor blade reservoir chamber, and a vacuum sensor switch (132) applies electrical power to an audio transducer (136). The audio transducer produces an audible alarm in response to an increase in doctor blade chamber pressure, thereby providing advance warning of an impending end seal failure or a worn doctor blade (94, 96) condition.

Abstract: In a tracking servo circuit, a tracking error signal obtained when disc player initialization is off is captured, its center level is calculated, the calculated center level is held in a register (17), and the center level held in the register (17) is subtracted from a tracking error signal obtained when the tracking servo is on. Consequently, an offset of the tracking error signal caused by a sensitivity imbalance between tracking servo photodiodes due to their aging or the like is detected as being securely corrected, thereby enhancing playability of a disc player in which the tracking servo circuit is used.

Abstract: The spindle shaft 50 is made flexurally elastic in its shank part 52 mounted in a bearing sleeve 20 and carries a warve 30 which is arranged underneath the neck bearing 60 and on which a drive belt engages. The bearing sleeve 20 is arranged in a spindle housing 10 with radial play 19 and is fastened at its lower end 22 via a flexurally elastic tilting joint 40 to the spindle housing 10 rigidly connected to the spindle rail. The pull of the drive belt which engages on the warve during operation deflects the bearing sleeve 20 radially according to the pull direction as a result of tilting about the tilting joint 40 and, on the other side, causes a pivoting of the bobbin-carrying upper part of the spindle shaft 50 about the neck bearing 60 in the opposite direction as a consequence of a bending moment occuring on the shank part 50. A skewing of the spindle shaft in its upper part is thus avoided. The textile spindle can be produced cost-effectively as a result of its simple design and the low stress loads in the tilting joint. <IMAGE>

Abstract: The method involves using a test device (13) and transparent, closable containers (2a-2n) in which liquids to be tested are placed. The containers are rotated about their longitudinal axes by friction rollers (5a,5b) at the end of an arm (3) rotating about the long axis (10) of a rotation device (4). The arm rotation transports the container to the test device. The test device contains at least a light source and sensor, in which particles set rotating by the rotation of the container are observed. The rotation of the container is caused by bringing its outer surface in contact with at least one friction surface, w.r.t. which it is displaced. The containers motion is stopped at the test device and the paths of the still rotating particles observed.
