Abstract: A METHOD OF CONTROLLING A PRINTER IN AN INTERACTIVE TEXT PROCESSING SYSTEM TO PRINT RECORDS FROM STORED FILES OF SPATIALLY RELATED DATA                 Abstract An improved method is disclosed for printing a file of spatially related data that is stored in an interactive text processing system as vector formatted records.  The method involves the operator establish-ing for the printer the number of print positions for a print line.  The method then involves transferring the field titles which make up the header portion of the file from storage to the print buffer sequential-ly, along with an indication of the maximum permissi-ble field width, which may be a simple underscore corresponding to that figure, until all of the field names have been transferred.  The process involves determining when a new print line is to be started for the header data in those situations where more than one print line is necessary to accommodate all of the field name data of the header.  The process merely involves determining if the next field in the sequence to be printed will fit in the space left on the print line previously specified and, if not, then entering carriage return signal after the last transferred field which, in effect, begins a new line.  The process continues until all of the field names have been transferred.  During the process a table is established indicating by line number and print position number where each field of a record starts. The actual vector formatted records may then be printed, using the data generated during the header transfer process to establish the line and print position where the corresponding data is to be placed.

The carrying case has a flexible backing sheet with storage pockets at each end.  One end of the backing sheet includes a main pocket and a secondary pocket with a single flap to close both pockets, these pockets being adapted to receive the tools and bulky items of needlework mater-ials.  The other end of the backing sheet includes a large pocket and a shallow pocket.  The large pocket is adapted to receive pattern books and the like while the shallow pocket receives a supply of thread.  Fastening devices are attached to the carrying case such that the backing sheet can be folded twice--into thirds--and fastening devices will hold the case in this condition; and, the backing sheet can be folded once---into half--and the fastening devices will hold the case in -this condition.  The case can be bent backwards or laid flat for access to the materials.

Abstract: ABSTRACT            In a pipeline through which a vehicle such as a pig is travelling, a magnetically activated detector detects the presence of the approaching pig and sends a signal to switch on a transmitter unit which supplies an alternating current to an AC coil.  The flux signal generates a magnetic field for a preselected period, the flux signal being then sensed by a pair of cross coil sensors on board the pig after which the signal is processed in a unit on-board the pig.  A reference pulse is then output.

Abstract: ABSTRACT OF INVENTION      A method and system for processing induction measurements of sub surface formations taken by an induction logging system at various depths in a borehole is disclosed.  The method reduces the unwanted contributions in each measure-ment from induction currents flowing in the formations spaced apart from each measurement depth.  The spatial domain sonde response function obtained at zero conduc-tivity is Fourier transformed and truncated at a spatial frequency less than the spatial frequency at which the transformed function first goes to zero.  A Kaiser window transfer function is then selected and the inverse Fourier transform of the ratio of the Raiser window function to the transformed truncated sonde response function is formed to obtain a deconvolution filter function which when convolved with the sonde response function reduces the non-zero sidelobes in the system response function and thus reduces the shoulder effect.

Abstract: "MULTI-PLANAR ELECTRODE PLASMA ETCHING"         ABSTRACT    Dry plasma etching of a plurality of planar thin-film semiconductor wafers is effected simultaneously and uniformly in a relatively small chamber enveloping a vertically-stacked array of laminar electrode sub-assemblies each of which includes a pair of oppositely-excited electrode plates tightly sandwiching a solid insulating layer of dielectric material, the parallel sub-assemblies being vertically separated to subdivide the chamber into a plurality of reactor regions where RF discharges can excite a normally inert ambient gas to develop reactive plasma for simultaneous planar plasma etching or reactive ion etching ( RIE ) of all wafers within the several regions.  The upper plates of the electrode sub-assemblies, which support the wafers during etching, are at any instant all maintained at the same potential, whether RF or ground in the different modes of operation, and fluid coolant is forced through a distribution of internal passageways in those support plates; all lower plates of the pairs are simultaneously maintained at the opposite potential, whether ground or RF, and the intervening insulating dielectric layers in the sub-assemblies are relatively thin while at the same time providing critical electrical isolation and curbing spurious discharge without serious electrical mis-matching.  Uncomplicated transport of individual wafers between vertically-stacked positions in a cassette and the stacked array of etching regions is accomplished from below by a reciprocatable arm which is receivable within accommodating slots recessed into the upper cooled electrode plates alongside one edge of the stacked array; programmed vertical movements of the cassette and electrode array allow for appropriate loading and unloading of wafers, and for proper orientation of the reactor regions in rela-tion to the enclosing chamber and associated equipment.

Abstract: ABSTRACT OF THE DISCLOSURE:         A device for separating solid particles of dirt from cooling water for power stations and the like has a screening drum disposed in a cylindrical casing so as to form an annular chamber.  An axially fitted dome is provided with a tangential inflow tube so that the incoming cooling water flows helically into the interior of the drum.  An outflow tube is secured tangentially in the casing, a baffle plate being disposed in the annular chamber in front of the outflow tube orifice.  Baffle plate bears by one edge coaxially against the outer surface of the drum and extends over part of the periphery of the latter, the distance from the drum increasing  n the direction of flow.  The baffle plate ensures uniform pressure distribution between the interior of the drum and the annular chamber over the entire periphery.  To flush out the accumulated particles of dirt, a discharge tube is connected to the interior of the drum and is opened for a short period at specific intervals by means of a valve.

The obstruction signal is for causing a collision in the CSMA/CD network.  The additional data communication network may be plural in number.  When the additional data communication networks are CSMA/CD networks, the transmission of data packets thereto is suppended when a collision is detected at the repeater.          The transmission is restarted a variable interval after disappearance of the collision.  The variable interval corresponds to a weighted random number known in the art.
