Abstract: LABEL PEELING DEVICE FOR LABEL ISSUING MACHINE            ABSTRACT OF THE DISCLOSURE        The disclosure concerns a label peeling device for use with a label issuing machine, such as a hand labeler or measuring printer.  There is a feed unit for feeding a label web, which web comprises a plurality of labels tem-porarily adhered in series to a web of backing paper.  A peeling unit turns and deflects the backing paper web rear-wardly, as it is being fed by the feed unit, and the labels peel one by one from the backing paper at the line of deflec-tion due to the rigidity of the labels.  An auxiliary label peeling member is arranged in the vicinity of that portion of the peeling unit at which the backing paper and the labels separate.  In some embodiments, the auxiliary peeling member has a label abutment portion so placed, shaped and sized that any label which might fail to peel from the backing paper merely by the reverse turning of the backing paper web is moved to abut the label abutment portion until it is forcibly peeled from the backing paper.  The auxiliary peel-ing member comprises a rotary member which is rotatable in , the advancing direction of the labels.  Any label, which might otherwise fail to peel off, abuts and rides over the rotary member.  In another embodiment  a scraper recipro-cates toward the deflection line along the surface of the backing paper from which the labels are peeled for peeling any label off the backing paper web.

Abstract: FAST PACKET SWITCHING SYSTEM            Abstract A communication method and packet switching system in which packets comprising logical addresses and voice/data information are communicated through the system by packet switching networks which are interconnected by high-speed digital trunks with each of the latter being directly terminated on both ends by trunk controllers.          During initial call setup of a particular call, central processors associated with each network in the desired route store the necessary logical to physical address information in the controllers which perform all logical to physical address translations on packets of the call.  Each network comprises stages of switching nodes which are responsive to the physical address associated with a packet by a controller to communicate this packet to a designated subsequent node.  The nodes provide for variable packet buffering, packet address rotation techniques, and intranode and internode signaling protocols.  Each packet has a field which is automatically updated by the controllers for accumulating the total time delay incurred by the packet in progressing through the networks.  Each processor has the capability of doing fault detection and isolation on the associated network, trunks, and controllers by the transmission of a single test packet.          The testing is done solely in response to the test packet and no preconditioning of controllers or networks is necessary.

Abstract: A B S T R A C T            A process and a means is described for burning solid fuels, preferably coal, in pulverised form mixed with a carrier liquid, such as water and/or oil or the like, to thereby form an emulsion.  The fuel emulsion is injected through a substantially annular entrance port into a combustion chamber so that an approximately hollow cone-shaped flow configuration is produced.  Within this flow configuration, a low pressure zone is built up immediately behind the entrance port for the fuel emulsion opening into the combustion chamber, so that a portion of the hot combustion gases and some unburnt fuel particles are recirculated to the entrance port.  Furthermore, gas entrance ports are provided in the end wall of the combustion chamber, through which the gas or air flows along a concentrical and spiral flow path towards the axis of the entrance port for the fuel emulsion opening into the combustion chamber.  In this way, the fuel emulsion injected into the combustion chamber is set in rotation, whereby the hollow cone-shaped flow configuration is fanned out or expanded to a bell-shaped or apple-shaped configuration.  This feature provides for an extremely long particle path in the shortest possible distance along the middle axis of the combustion chamber.          Practically complete combustion is ensured within an extremely short combustion chamber.

Abstract: ADDRESS SEQUENCER FOR PATTERN PROCESSING SYSTEM             ABSTRACT OF THE DISCLOSURE        An  address  sequencer          produces  an address   stream  which   includes   a  plurality  of interleaved sequences of addresses. Each sequence is a function of input data which is received when an input pattern is sampled by that sequence, so that a repetitive   address   loop   is   generated   which characterizes  the  pattern.   The  address  sequencer includes  a  shift  register          with  a programmable  feedback  circuit which provides a feedback bit to the first stage of the  shift  register         based  upon  bits  from selected stages of the shift register       .   During each operating cycle of the address sequencer a counter        provides  a  sequence  identification number  which  identifies  a  particular  sequence.   A stored    address    selected    by    the    sequence identification  number  is  provided  as  the  present address  for  that  sequence  (and  the  output  of  the address sequencer).          In  addition,  the  shift register       is loaded with a multibit word derived from that stored address.  The shift register is then shifted a predetermined number of times, and the feedback bit is derived from stages of the shift register         which  are  selected  based  upon  the sequence identification number.  The next address of the  sequence  is  derived  from  the  contents  of  the shift  register         after  the  shifting  and  is selected based upon a comparison of the input data (which  was  received  in response  to  the  present address) with a reference value.  The next address is stored   for   use   the   next   time   the   sequence identification number for that particular sequence occurs.  A new cycle is then commenced by providing a new sequence identification number from the counter .   The production of  interleaved  sequences  of addresses in the addressed stream enhances resolution of  the  pattern  processing  system,   and  permits processing of an image which contains a grey scale.
