Abstract: ANTENNA CONSTRUCTION Abstract of the Disclosure A construction, suitable for use in compact frequency reuse communications antenna, includes two superimposed reflectors; each reflector includes element support structure comprised of Kevlar honeycomb and Kevlar fabric sheets on the faces of the honeycomb and parallel, spaced, elongated reflector and Kevlar elements extending over one of the face sheets; the two reflectors are spaced from one another by ribs formed of Kevlar honeycomb material and Kevlar face sheets. The directions:  (a) in which the ribbons of the honeycomb cores of the support structures of the respective reflectors extend, (b) in which the reflective elements of the respective reflectors extend and (c) in which the fabric warps of the face sheets of the respective reflectors extend are chosen to minimize thermal and other distortions and RF losses within the construction while providing the construction with high natural frequency and low weight.

Abstract: Abstract:           SECONDARY MATRIX REINFORCEMENT USING CARBON MICROFIBERS AND METHOD FOR MAKING CARBON MICROFIBERS     A continuous fiber composite having carbon micro-fibers dispersed  in the  resin filling  the  interstices between the continuous fibers to enhance the transverse properties of the composite.  The carbon microfibers are made by soaking carbon fibers in an intercalating acid solution  comprising  a  mixture  of  fuming  nitric  and sulfuric acid  to  weaken  the  intercrystallite  bonds.          Gentle  stirring  of  solution  separates  the  carbon microfibers from the host fibers.   The microfibers are then separated from the intercalating acid solution and washed to remove the residual acid.

Abstract: Abstract of the Disclosure A keyboard system has a keyboard geometric arrange-ment enriched in intersections of three keys achieved by offsetting or staggering adjacent keys.  This provides a greater number of choices from a given number of keys actuable manually one, two or three at a time.  The key layout permits touch typing with one hand where twelve keys provides full alphanumeric capabilities.  Finger positions conform with human hand structure and include raised ridges for identifying some of the fingerstroke key selection locations.  Thus, accurate high speed typing with either hand is feasible in a telephone dial space frame.  The keyboard communicates by an X by Y communication channel matrix or telephone system compatible tone signals with computers, telephones, teletypes and like utility devices. Program steps and function selection is afforded by a self-cataloged two (or more) keystroke sequence to reduce programming time and increase the number of selections possible per key.  Thus, as few as four keys and four wires can afford fourteen manual selections by a single fingerstroke in a single live key mode.

Abstract: ABSTRACT In track systems based on the two-track pin principle having connectors arranged on the track pin ends, considerable loads are imposed on the track pins as a result of the fact that drive sprocket teeth mesh with the connectors.  This means that the rubber bushings and the track pins and the track plates themselves have to be of suitable dimensions.  By arranging the connectors (7,8; 45; 50) within the track plates (1,6) meshing of the drive sprocket in the track plate can be arranged so that the track pins (4; 42; 55) are relieved of the stresses caused by the meshing process, and for this reason the above component elements can be of smaller dimensions.  Simple installation and removal of the track plates (1,6) is made possible by the configuration of the connectors (7,8; 45; 50) as two clamps (17,18; 47,48; 53,56) that can be inserted into each other and connected to each other by means of a screw connector (30;49).

Abstract: A B S T R A C T     The invention relates to a bundle limbing device, primarily for mobile use.  The bundle limbing device is divided into two mirror-symmetrical halves, each with one front and one rear swinging arm at their lower parts mounted on a low level e.g. at the stakes of a forwarder and interconnected by means of longitudinal bars.  At the ends of the swinging arms of each device half front and rear bearing beams are rigidly secured, which serve as bearings for a series of parallel limbing rolls.          Support shoulders at the top of the swinging arms form side supports for a bundle of trunk portions which are deposited on the bed formed as the two device halves are brought together when the opposite bearing beams on the associated swinging arms meet and form an obtuse angle.  Each limbing roll consists of a centre tube which supports a series of circular annular flanges with alternating inclination to the tube shaft defining an elliptic rotational surface.  All the rolls in each device half are first driven by means of a transmission in a direction in which the trunk portions lying above are carried along outwards towards the support shoulders while they are limbed and stirred which is promoted by the elliptic vibration.  Branches then detached will pass out through openings between the outer rolls and the support shoulders.  After finished limbing the two device halves are separated while reversing the direction of rotation of the rolls so that the limbed trunk portions are passed down into an underlying load space.

Title: Cyclic phenolorganosilanes and process for their  production

IPC: C07F7/14

Granted: 1990-01-30
Abstract: ABSTRACT OF THE DISCLOSURE:     The present invention relates to cyclic phenol-organosilane-esters and to the o-allylphenylsilane-monoesters occuring during the production thereof.  The benzene nucleus of these new compounds is preferably substituted with chlorine or methyl radicals;  these compounds are suitable for bio-resistant preserving and sterilizing of natural and artificial materials.  Some of the compounds claimed are also suitable for adhesives and for smoothing glass fibres.  These new compounds are produced mainly by known processes.  However, in producing o-allylphenylsilane-monoesters, it is necessary in many cases to operate in the presence of an excess of hydrogenchlorosilanes.  The cyclizing of this preliminary stage to the end-product is carried out in the presence of platinum and/or rhodium catalysts, according to the addition-reaction known per se.  This cyclizing may also be carried out without isolating the o-allylphenolsilane-monoester, in that the starting products used for these intermediate pro-ducts are fed directly after the reaction or, if trichloro-silane is used as a starting product, directly after mixing, to the cyclizing reactor.  These special processes are also objects of the present invention.

Abstract: ABSTRACT   The invention relates to a method for purifying aqueous solutions containing at least one impurity element from the group consisting of arsenic, phosphorus, mercury and other heavy metals and solid matter by precipitation in at least two stages with the aid of precipitation reagents possessing ions capable of forming not-readily dissolved hydroxide precipitate. In accordance with the invention the main part of the precipitation reagent is introduced to the stage or stages following the first stage. The impurity element-containing precipitateformed in the aqueous solution subsequent to adding the reagent is separated therefrom substantially completely, and is returned so as to be present in the first precipitation stage, while that part of the solution which has been freed from precipitate in a later stage is withdrawn from the system. Substantially all the impurity element amount present in the ingoing aqueous solution are separated therefrom in the form of a sludge prior to the second precipitation stage.   The amount of reagent introduced to the precipitation stages is suitably adaptedso that the ratio of equivalence Me to mole of impurity elements, expressed as X is at least 2, preferably 10-15, in the last stage, and at least 0.8, pre-ferably 1-3, in the first stage.

Abstract: ABSTRACT           A data transmission network includes a number of access controllers connected to a central hub.  The hub includes an arbitrator to select only one access controller for data transmission.  Upon selection of one controller all other controllers are disabled to prevent collision of data packets.  An interlock prevents enablement of a disabled controller until the data packet received by the transmitter has terminated to prevent transmission of part of a data packet. Synchronisation between the data and a master clock is obtained by an initial coarse synchronisation and a subsequent fine synchronisation.  The coarse synchronisation is obtained by generation of a number of identical signals with a time delay between each signal. A clock pulse latches to one of the signal paths to provide the initial coarse synchronisation.
