Patent EP-0317232-A2 (EP)
Inventor: JOHNSON PETER E
IPC: B65H3/08
Filed: 1988-11-14
Abstract: A plate feed apparatus comprises a rotary carrier (22) which provides a plurality of semi-spherical gripping heads (34) having concave gripping surfaces (36). The gripping heads (34) are positioned such that the gripping surfaces (36) become flush with the forwardmost plate (14a) in a vertically arrayed stack of plates as the carrier (22) rotates. Each gripping head (34) is mounted to the carrier (22) through a hollow bellows (40) and vacuum air drawn into a hole (37) in the gripping face passes though the bellows. When the vacuum increases, due to the forwardmost plate (14a) in the stack being pulled up against the gripping head, the bellows (40) collapses and pulls the forwardmost plate away from the stack. Rollers (42), which extend beyond the periphery of the carrier (22), urge the stack away from the gripping head (34) immediately before they become aligned. The vacuum then pulls the forwardmost plate (14a) away from the stack and into contact with the gripping head (34) before the bellows (40) collapses thereby increasing the gap between them. Vacuum is provided to the gripping head (34) through a passageway which opens out of an opening (46) in the carrier (22). A first sector plate (48), which is journaled on the carrier axle (26) but does not rotate with the carrier, has a slot (50) passing through it which overlies the opening (46) in the carrier when they are aligned. A second sector plate (52), which   overlies and is attached to the first sector plate (48), has a hole (54) in it which opens into the slot (50) in the first sector plate. A vacuum tube (56) extends between this opening and a vacuum source.

Abstract: A process for treating a carbon layer of a magnetic recording medium, includes the steps of enclosing a magnetic recording medium within a chamber (36), the medium including a substrate (18), a recording layer (24) of magnetisable material formed over the substrate, and an outer carbon layer (26) over the recording layer. An inert gas plasma at a pressure substantially less than atmospheric pressure is generated and maintained within the chamber (36) for an amount of time substantially to clean exposed surface areas of the carbon layer (26). Following the cleaning, a plasma mixture at a selected pressure substantially less than atmospheric pressure and at a selected temperature is generated and maintained within the chamber (36) for a selected time to fluorinate at least a portion of the carbon layer (26). The plasma mixture consists essentially of a reactive gas and an inert gas, the reactive gas comprising at least 60% by volume of the mixture and being carbon tetrafluoride and/or fluorine. A similar process is applicable to treating an exposed surface of a slider body formed of a ceramic material.

Abstract: An aircraft guidance system for flying an optimal inertial flight path in a windshear encounter. Zero inertial flight path angle command is utilized as the basis for guidance commands for either horizontal or vertical windshears; the flight path angle command is constant regardless of the actual magnitude of the shear. The effect of the guidance law described is to provide a zero inertial flight path angle to prolong excitation of the aircraft's phugoid oscillatory mode. By utilizing inertial flight path angle derived from an inertial reference system, errors introduced by vertical gyroscope systems are eliminated and thus a very accurate flight path angle guidance law is produced. The described guidance control law maximizes the aircraft's time in the air during a windshear encounter. Protection against aircraft stall is also provided by using a computed variable maximum allowable angle of attack (Fig. 3).

Abstract: A method and apparatus are specified for testing ferromagnetic materials with magnetic powder, in which the workpiece is introduced into an elongated air coil (1 - 4) with ends bent at right angles. The full magnetic field flows through the workpiece (21). The defects in the workpiece are preferably detected at its top while the magnetic powder (20) is picked up at the bottom and the workpiece is rotated through at least 180 DEG  for observation. The apparatus makes it possible for a workpiece to continuously pass through it, with a continuous observation of the surface of the workpiece being possible at the same time as it is rotated and it being possible to detect transverse and longitudinal defects simultaneously or consecutively. The magnetic flux through the workpiece is produced without touch and without contact. The invention makes possible simple, precise and rapid surface defect testing of ferromagnetic materials without making contact to the workpiece or adjusting the testing apparatus. <IMAGE>

Abstract: The invention relates to an electromagnetic switch apparatus having a magnet system with yoke and armature, the armature of which has switch contact parts lying mutually adjacent transverse to the direction of actuation with a contact support guided in the casing of the switch apparatus, which switch contact parts form normally-open or normally-closed contacts with stationary contact parts, and in which support or entrainment stops are provided for the switch contact parts. 
<??>The contact supports are guided in the housing with play, so that tilting is possible. With respect to this tilting motion, the free path, that is to say the path which is necessary from the lifting of all normally-closed contacts to the resting of all normally-open contacts, must be set to the normally-closed contact lifting last. 
<??>In order to keep this free path relatively large, the stops facing the casing walls are located in advance of the middle stops in the direction of motion, so that the free path lost by the tilting is thereby gained again. In this way, the force required can be kept lower in comparison to the conventional design, since it has a favourable effect on the traction curve.

Abstract: For a compatible color television system suitable for high and low definition on display, a MAC-system is taken as an example. Herein use is made of a digitally assisted DATV. To effect a bandwidth reduction encoding and bandwidth reduction decoding, use is made, in addition to the MAC-coding and MAC-decoding, of at least three picture signal channels (PC) each having a different picture signal refresh period equal to, for example, 80, 40 and 20 ms which are coupled  via  a time-division multiplex circuit (MUX). For with the diversity of picture signal sources, it was found that distinguishing during the picture signal processing between a film mode (SW1, T40) and a non-film mode (SW1, T20) results in a significantly improved high-definition picture resolution. This distinction is expressed at the DATV by one information bit (FM′). During the non-film mode (SW1, T20) three Y-luminance channels (PC11, PC13 and PC12) of 80, 40 and 20 ms and two U and V-chrominance channels (PC21 and PC22) of 80 and 20 ms are operative. During the film mode (SW11, T40) the Y-­channels (PC11 and PC13) and the U and V-channels (PC21 and PC23) of 80 and 40 ms are only operative.

Abstract: A BiCMOS current source reference network which eliminates the impact of d.c. power supply voltage drops on the operation of ECL circuits is described. This invention is essential for implementing ECL design techniques in VLSI BiCMOS circuits. Using the current source network, reference voltages are generated locally so that the ECL voltage references are correctly referenced to the local power supply potentials. A power supply insensitive band-gap reference generator is used to generate precision on-chip voltage references and current sources. The band-gap circuit uses both MOS and bipolar transistors and is much simpler than a similar using bipolar-only circuitry.
