Abstract: Abstract of the Disclosure Apparatus for producing a scan pattern for the omni-directional reading of bar code indicis.  The scan pattern is formed by the generation of two sets of diagonal lines that are directed upon a reflecting surface.  The first set of lines intersects the second set at an angle of approx-imately 90° on the reflective surface that is deflected to impart translational movement of the pattern.  This trans-lational optical scanning pattern insures readability of a bar code bearing indicia regardless of the angle at which the indicia is conveyed past the reader.

Abstract: DATA AND SIGNALING MULTIPLEXING                IN PCM SYSTEMS VIA THE FRAMING CODE                    Abstract of the Disclosure A subsystem is added to an existing PCM system to provide N additional data channels and to increase the number of signaling channels.  The subsystem includes a framing code generator to produce a framing code having a data code bit position for each of 6N system frames with certain of the bit positions having a distinctive pattern of code bits to provide frame synchronization for the receiver of the existing system and the receiving portion of the subsystem.          The N additional data channels are time multiplexed by timing signals from the frame code generator and then the frame code generator inserts each channel of N time multiplexed channels into a different one of N others of the code bit positions to convey the additional data in the framing code without altering the distinctive pattern of code bits.  The framing code generator also provides other timing signals to increase the number of signaling channels.  A framing code receiver of the subsystem recovers the additional data channels from the framing code, the additional signaling channels and synchronizes the system and subsystem in response to the distinctive pattern of code bits.  The subsystem may be converted to Western Electric D2/D3 compatibility by opening a strap on each of the framing code generator and framing code receiver.

Abstract: Abstract of the disclosure:        A process for the preparation of xanthene dyestuffs of the general formula        , (in which R1 and R2 are identical or different, each re-presenting an optionally substituted aliphatic or op-tionally substituted araliphatic or cycloaliphatic radical, or R1 represents also a hydrogen atom or a carbocyclic aromatic or heterocyclic radical, or R1 and R2 together with the N-atom form a heterocyclic radical optionally containing further hetero-atoms, the benzene nucleus A may optionally contain substituents, and m stands for the integer 1,2, 3, 4 or zero) had been found wherein the inner salt of a 3,6-dihalogeno-9-(2'-sulfophenyl)-xanthene-9-ol of the formula   (in which X stands for a halogen atom and A has the above-mentioned meaning) is reacted with a primary or secondary amine of the formula    , (in which R1 and R2 have the meanings specified as above) in a polar solvent which is free from acid groups; to obtain the sulfo compounds, the product is subsequently sulfonated.  The improvement in this process is to carry out the reaction of the xanthenol with the amine in stoichio-metrical amounts and in the presence of an inorganic acid-binding agent and/or an acid-binding tertiary aliphatic or cycloaliphatic amine, of pyridine or of a pyridine deri-vative.  The novel process has the advantage of yielding dyestuffs of high quality with a strong color intensity and brilliancy, a high fastness to light and a uniform dyeing behaviour.  Furthermore, the dyestuffs are obtained in very good yields avoiding the high charge of the waste water of present processes of the dyestuff itself or its starting components used in excess.

Abstract: ABSTRACT      Fuel gas produced e.g. in a fluid bed gasifier and which comprises deposit-forming materials such as heavy hydrocarbons (e.g. tars)  and non-combustible fines is passed via conduits and solid-removing cyclones to a burner for admixture with air and subsequent combustion.  Deposits formed in the conduit cyclone and burner are removed by closing off the burner outlet and air inlet, and passing  deposit-removing, reactant (e.g. air) into the conduit to oxidize and thereby remove deposits, particularly from the cyclones.  Preferably, there are at least two burners for the fuel u gas, and they are closed off alternately to remove deposits from their respective conduits and cyclones.

Abstract: ABSTRACT          The invention relates to a control device for a hydraulically operated consumer which is suppliable with pressure fluid from a source of pressure medium through a supply conduit, a control unit and a service main on the inlet side and is connectible to a tank through a service main on the outlet side, the control unit and a return conduit, wherein the housing of the control unit contains control apertures associated with the supply conduit, the service mains and the return conduit, which apertures are connectible in pairs in the operative position by means of a control slide which blocks the supply in the neutral position.  The supply conduit is associated with a pressure differential regulator which is influ-enced in one direction by the pressure in the supply conduit and in the opposite direction by a spring and by the pressure in a sensing conduit connected to the service main on the inlet side.      The control slide and housing form two switching valves of which one connects the sensing conduit to the return conduit in the neutral position and the other connects the sensing conduit to the service main on the inlet side in the operative position and blocks this position is the respective other position.  The housing of the control unit is provided with two interconnected control aper-tures associated with the sensing conduit, of which one is dis-posed on the one side of a return conduit control aperture and the other is disposed on the opposite side of a return conduit control aperture.  The control slide comprises two first sensing conduit valve apertures which, in the neutral position, connect the two sensing conduit control apertures to the associated return conduit valve apertures which, in the neutral position, connect the two sensing conduit control apertures to the associated return conduit control aperture.  Thus the valve connecting the sensing conduit to the return conduit in the neutral position is provided directly on the control slide in the form of a double valve, and no time delays therefore occur.

Abstract: NOISE BURST SOURCE FOR TRANSFER FUNCTION TESTING     Abstract of the Disclosure A method and apparatus for accurately measuring the transfer function of a linear system or the linear part of a non-linear system.  This is accomplished by using a spectrum estimation technique which utilizes a "transient random" stimulus consisting of a short burst of random signals applied to a system under test for a period of time that is shorter than the time used to measure a single spectrum.  Thus the measurement period includes the time for the "transient random" burst and for the response of the system to substantially decay to zero.  The spectrum measured over this period is used to form a first estimate of the transfer function.  Other "transient random" stimuli, uncorrelated with the prior records, are then generated and the above procedure is repeated to achieve an average value for the transfer function estimate of the desired accuracy.  Through the use of several "transient random" stimuli, leakage and distortion in the measurement are minimized, thus greatly improving the accuracy of the estima-tion technique in measuring the transfer function of the system under test.
