Abstract: ABSTRACT OF THE DISCLOSURE    A device for measuring the rolled-up length of web forming a roll when a web break has occurred during forma-tion of the roll employs a web break indicator to indicate a web break.   Normal  web length measuring  is  carried out  by  counting pulses from a  pulse transducer driven by a roller turned  by the moving web and this is stopped on web break.   A calculation of  the  circumference  of the web roll on the occasion of the web break is made with the further aid of a pulse transducer on the shaft of the web roll and a counter and logic unit.  Too loosely wound web material is removed from the roll and the cir-cumference of the roller decreases.   After joining the web and renewed winding, a calculation of the roll circum-ference is continuously performed by means of the pulse transducers. When the circumference of the roll resumes the  size it had at the moment the web break occurred, normal length measuring is automatically resumed.

Abstract: ARRANGEMENT FOR DETERMINING THE TRAVEL OF A PISTON     ABSTRACT OF THE INVENTION      A contactlessly, measuring arrangement for determining the position of a piston in a suspension component such as a vibra-tion damper, gas spring or hydro-pneumatic suspension.  In one embodiment, the piston and/or the piston rod of the suspension component and a further electrode are mounted inside the cylinder of the suspension component to form a variable capacitor which, with the aid of other circuitry, measures the position of the piston.  The further electrode preferably is in the form of a tube extending from the base of the cylinder into a hollow cylinder formed within the piston rod which receives the tube. In the capacitive embodiment, additionally, there may be provided a further tube within the first tube to form a reference, second capacitor which is sensitive to pressure and temperature in the same manner as the first capacitor.  The first capacitor serves as the variable capacitor for making a position measurement of the piston and the two tubes fixed relative to one another are employed to form the reference capacitor.  In an alternative capacitive embodiment, a medium, such as a ceramic or epoxy resin cylinder enters between two electrodes, the extent of the entry of the dielectric medium being made to be proportional to the relative travel of the piston in the cylinder.  In a further alternative embodiment, the outer surface of the cylinder has an inductive coil wound therearound for producing a magnetic field which is variable dependent upon the position of the piston within the cylinder.  Both measuring arrangements when connected in a Wheatstone Bridge circuit produce an electrical signal indicative of the position of the piston.

Abstract: ABSTRACT     DATA CAPTURE SYSTEM    The system involves the fitting of Electronic Number Plates (ENP's) to all road vehicles with roadside interrogators (outstations OS) and central control equipment to collect and validate vehicle identity data before passing it on to an accounts processing system AP.          The system is organised so that there are a number of vehicle data processing devices (Data Validators DV) which receive data from the outstation units (OS) interrogated by a communications controller (CCL).  Each Data Validator (DV) is allocated a discrete subset of all vehicles in the system to enable vehicle location checking to be maintained as the vehicles move through the system.  Any apparent error in vehicle data is passed on to a supervisory processor which checks if the error can be explained.  This provides a powerful vehicle location consistancy check and fraud identification system allowing speed detection of fraud, stolen cars or electronic number plates.

Abstract: METHOD AND APPARATUS FOR           DYNAMICALLY SEGMENTING A BAR CODE                         Abstract A method and-apparatus are disclosed for reading a two-dimensional bar code having bars located nominally at predetermined pitch increments.  The invention provides a method and apparatus for reading a two-dimensional bar code and dynamically segmenting it into individual bars on a real time basis, as it is read.  The segmentation is done on a bar-to-bar basis, and may be adjusted for an indivi-dual bar as necessary.  The method and apparatus locate the bar data, scan it, and create a profile vector having ele-ments based upon the amount of image data in each scan.          The vector is compared to a predetermined stored set of vector elements representing the likelihood that each scan line of image data contains bar image data.  Those scan lines of image data corresponding to a bar image are sent to recognition logic and those scan lines of image data corresponding to a space are disregarded.

Abstract: Fluidized Bed Reactor and Process for the Operation of a Fluidized Bed Reactor.            ABSTRACT       A process for the operation of a circulating fluidized bed re-actor is described by which a solid particle material comprising a solid reactant material in particular carbonaceous fuel is introduced into the lower part of the reactor and is formed to a fast bed by means of a fluidization gas containing a gaseous reactant material in particular oxygen introduced into the reactor bottom, while non-reacted particles are removed from the reactor top and recirculated to the bed.     By removing a predetermined fraction of the solid particle ma-terial being present in the reactor from at least one site positioned below the reactor top subjecting it to thermal treatment and recir-culating it to at least one other lower positioned site of the bed enhanced possibilities for process optimalization are achieved.     Furthermore a fluidized bed reactor is described comprising a vertical reactor chamber (1) a first inlet (9) in the lower part (2) of the reactor chamber for introduction of solid particle material and a second inlet (22) in the bottom of the reactor chamber for introduction of fluidization gas and an outlet conduit (28) in the upper part (4) of the reactor chamber for removal of reactor mate-rial.     Such a reactor may be used for performing the described pro-cess when at least one further outlet conduit (5, 3a, 3b, 4) for solid particle material is provided between the first inlet (9) for solid particle material and the outlet conduit (28) for reactor mate-rial which outlet conduit (5, 3a, 3b, 4) via cooling or heating members (21) leads back to the reactor as at least one further inlet for solid particle material.

Abstract: ABSTRACT         An in-phase combination type diversity receiving system includes a local oscillator and a first frequency converter for converting a first signal to an IF signal by using the output of the local oscillator.  Also included are an endless phase shifter for phase-shifting the output of the local oscillator and a second frequency converter for converting a second signal to an IF signal by using the output of the endless phase shifter.  The IF signals outputted by the first and second frequency converters are com-bined in a combinder.  An automatic gain controlled (AGC) IF amplifier is provided for amplifying the output of the combiner and a level detector is provided for detecting the AGC voltage of the IF amplifier.  A memory stores the output of the level detector.  A comparator compares the output of the level detector which appears when the endless phase shifter is shifted by a pre-determined phase amount and the output of the memory corresponding to the output of the level detector which appeared before the shift of the endless phase shifter.  An absolute value and a polarity of the difference between the two outputs is thereby obtained.  A decision unit decides whether the absolute value is greater than a predetermined value and a sign discriminator discriminates the polarity of the difference.  A phase shifter controller is con-structed, when the absolute value is not greater than the predeter-mined value, to phase-shift the endless phase shifter by another predetermined phase amount and, when the absolute value is greater than the predetermined value, to store the output of the level
