Title: Inductive displacement sensor with an air coil and a core plunging into the air coil, the in each case instantaneous length of engagement of which is to be sensed
IPC: G01D5/20
Filed: 1981-01-26
Abstract: The invention relates to an inductive displacement sensor having two magnetic circuits which are largely decoupled from one another, of which a core controlling the in each case electromagnetically effective length of displacement determines the ratio of inductances of the magnetic circuits in at least one circuit and the ratio of inductances is preferably determined by measuring the frequency ratio between two oscillator frequencies, the inductances of the magnetic circuits in each case being connected, largely decoupled from one another, in a frequency determining manner in an oscillator. The sensor according to the invention senses in a directly integrating manner and the core to be sensed must not be tightly enclosed by the coil. The sensor is therefore particularly suitable for directly sensing floating bodies.

Title: Verfahren und vorrichtung zur spektralanalytischen untersuchung von werkstuecken aus eisen- und stahllegierungen
Inventor: GRISAR ULRICH DR
IPC: G01N21/67
Filed: 1982-04-14
Abstract: Zur Erzielung weitgehend störungsfreier Halbleiteranordnungen, insbesondere von integrierten Schaltungen, werden die in üblicher Weise für die Wärmebehandlung gereinigten Halbleiterschalen unmittelbar von der Reinigungsanlage in den der Wärmebehandlung dienenden Ofen gebracht, ohne daß die Halbleiterscheiben mit dem Außenraum in Berührung kommen. Aus diesem Grunde wird die die thermisch zu behandelnden Halbleiterscheiben tragende Horde mit Abstand von der Rohrwand in das die Halbleiterscheiben während der Wärmebehandlung aufnehmende Quarzrohr eingeschoben und dort gleitungsfrei aufgesetzt. Ebenso wird bei der Beschickung der Horde mit den Halbleiterscheiben jede Reibung der Halbleiterscheiben mit der Horde bzw. dem die einzelnen Halbleiterscheiben lediglich am Rande berührenden Greiforgan vermieden. In Fällen, bei denen eine gleitende Bewegung miteinander in Berührung stehender fester Körper in Gegenwart der Halbleiterscheiben unvermeidbar ist, wird die Relativgeschwindigkeit dieser Körper zueinander auf höchstens 5 mm/sec beschränkt. Außerdem wird die Übertragung der Halbleiterscheiben von einer Horde auf die andere Horde, z.B. von der Reinigungshorde auf die der Wärmebehandlung dienende Horde, unter Einfluß einer Absaugevorrichtung vorgenommen. Durch diese gemäß der Erfindung anzuwendenden Maßnahmen wird erreicht, daß die Oberfläche der Halbleiterschalen vollkommen staubfrei ist, was der Qualität der erhaltenen Halbleitervorrichtungen in erheblichem Maße zugute kommt.

Title: Motor hoe for horticulture
Inventor: JOHN DIETER
IPC: A01B33/10
Filed: 1982-04-24
Abstract: Motor hoe for horticulture, consisting of a tube, on the lower end of which the working part is provided in a known way and at the upper end the drive, the working part having a hexagonal axle, onto which the hoeing stars or cutters can be pushed. Depending on the working width required, more or fewer hoeing stars having the same shape and the same mutual spacing and working the soil uniformly are pushed onto the axle. Since the number of hoeing stars is matched specially to each working width, a uniform working of the soil also takes place. In contrast to known motor hoes, where there is the same number of hoeing stars for narrow working widths as for large working widths, here the hoeing stars are always matched in number to the particular working width. This is a precondition for the correct thorough working of the soil. The appliance is of light-weight construction, and its holder bears on the body during work, with the result that the appliance is easy to handle and can be shifted from place to place on the ground.

Title: Pivoted segment sliding-contact thrust bearing
Inventor: GERLING PAUL
IPC: F16C17/06
Filed: 1982-05-15
Abstract: The invention relates to a pivoted segment sliding-contact thrust bearing with a bearing ring divided into individual pivoted segments, a supporting ring and a pivoted-segment holder for the pivoted segments mounted pivotably on the supporting ring. For each pivoted segment, the pivoted-segment holder has a radial pin and an axial pin. The radial pin is secured in an outer collar of the supporting ring and engages in a radial bore of the pivoted segment with predetermined play. The axial pin is releaseably secured on the inside in the supporting ring and engages in an inner axial bore of the pivoted segment with predetermined play. On the inside, the pivoted segment has a recess in which the axial pin engages with one of its ends, this end being designed to receive a securing element. Simple and functional holding of the pivoted segments is thereby achieved, which guarantees operational reliability even after multiple assembly and disassembly and, in particular, makes possible the individual removal of any of the pivoted segments. In addition, the interspaces between the pivoted segments now remain free, making satisfactory supply of the pivoted segments with lubricating oil possible. <IMAGE>

IPC: B41F33/00
Filed: 1982-06-03
Abstract: A machine for scanning printing plates to determine the ratio of "printing" to "non-printing" area for pre-adjustment of the ink dosing elements of a printing machine has an array of electronic photo-sensors, each sensor being disposed in a channel having low-reflection chambers which permit sharp delimination of resolution elements on the printing plate and ensure high definition scanning of different types of printing plates under practical conditions. Preferably the diaphragms dividing the channel into chambers have greater spacing at greater distances from the element sensed on the printing plate. To accommodate printing plates of different materials, means are provided for selecting the wave length of the light source. To prevent measurement error due to changes in the distance from the printing plate to the light source and sensor array, the photosensor array is preferably directed or aimed 60 DEG to 45 DEG  with respect to the normal vector of the printing plate, and the light source is in the same quadrant as the photo-sensor array at an angle of 0 DEG  to 45 DEG  with respect to the normal vector. Automatic calibration, automatic printing plate size determination, automatic sensing of identification information engraved on the printing plate, and a stairstep scan to increase the scanning rate are provided by suitable procedures executed by a microcomputer controlling the scanning process and analyzing, adjusting, and interpreting data received from the sensor array.
