Abstract: TIME DIVISION TELECOMMUNICATIONS SYSTEM          ABSTRACT OF THE DISCLOSURE:         A telecommunications  system which  is capable of implementation  in many configurations.    The  simplest  and smallest  configuration  is  that of  a single processor-con-trolled module or unit using time division switching.  Within a module, a processor and its attendant memory provide program memory and control the functioning of an automatic scanner driver, the automatic scanner driver interfacing between the processor and the system terminal circuits.  In addition the automatic scanner driver has capability of storing temporary information during call processing through a time division switching network.   For configuring larger systems, plural modular units are combined,  the units being combined with control  elements  common  to  the  system  such as  a control processor, including memory and a processor to module inter-face and module to module interface.  The common elements act to control the feeding of information between modules.   In this way, one family of systems may provide systems of any desired size from small (50 lines) to many thousand lines.

Abstract: ABSTRACT OF THE DISCLOSURE A slide fastener comprises two continuous plastic filament (synthetic-resin monofilament), each with o multiplicity of ge-nerally helicoidal coupling elements for interlocking with the coupling elements of the opposite filament, each filament being woven integral with the threads of its respective support tape to form a tape-like unit.  Each  coupling element has a coupling head on a loop end and a pair of shanks terminating in bight portions which connect elements of the same tape-like unit.  The shanks of each coupling element, which separate the bights from the loops, are held in close abutment by warp threads, with or without weft threads which pass over and under the successive paired abutting shanks of adjacent elements.  Even stronger bracing can be obtained with bulbuous projections on the shanks and bights, and by extend-ing the coupling elements the entire width of the tape-like unit, replacing all or part of the weft threads.  Thus the shanks can extend transversely to the warp over a substantial part or all of the tape-like unit to form the exclusive weft over this part or the entire width of the tape.

Abstract: METHOD AND APPARATUS FOR ADDRESSING          A CHARACTER GENERATOR                ABSTRACT Method and apparatus for supplying to marking means, character bit data from a two-dimensional matrix of rows and columns of storage elements wherein char-acter selection is made by specifying the character storage cell and character width.  Characters are symmetrically stored about the vertical axis of a preassigned matrix having an even number of columns and the binary width data are translated as starting and stopping addresses on opposite sides of the axis for readout of columns therebetween.  The center storage of the character with clear margins enables the raw binary width data to be used as one edge address and its complement to be used as the other address in determining the width of the character to be retrieved and printed.  Proportional spacing and justification are simply achieved by varying the width data as required.

Abstract: Abstract of the Disclosure A compound is chlorinated with chlorine to produce chlorinated product and hydrogen chloride byproduct.  Recovered hydrogen chloride byproduct is contacted with oxygen and a molten salt mixture containing the higher and lower valent chlorides of a multivalent metal, such as cuprous and cupric chloride, to effect recovery of the hydrogen chloride by enriching the molten salt content of the higher valent chloride.  The molten salt, enriched  in higher valent chloride, is then dechlorinated by use of a stripping gas, preferably hydrogen chloride, to produce a gaseous effluent containing stripped chlorine and the stripping gas, which is then recycled to the chlorination step.  The presence of stripping gas, as a diluent, improves the chlorination operation.

Abstract: 26.10.1978                  1                     PHN.9076 ABSTRACT:     The invention relates to a multilayer inform-ation disc, in particular a video disc, which is read by means of laser light. The disc comprises at least two ra-diation-reflecting optical structures each having a relief-like information track of regions situated alternately at a higher and a lower level which is read in reflection and on the basis of occurring phase differences. The optical struc-tures are covered with a reflection layer. According to the invention at least one optical structure is covered with a reflection layer which partially transmits the reading radiation. Upon reading the other optical structure or structures the reading radiation passes through the struc-ture provided with a partially transmitting reflection layer. In a favourable embodiment the disc comprises a transparent substrate plate which is provided on one side and which upon reading the disc is irradiated by the read-ing beam. The coefficients of reflection of the various optical structures are preferably matched to each other in such manner that upon reading the same amount of light, re-turns from each optical structure. A suitable partial re-flection layer is a dielectric layer which shows no light absorption.

Abstract: METHOD AND APPARATUS FOR PROCESSING VEHICLES MOVING THROUGH A CONDUIT BY AIR                         Abstract A method and apparatus for processing vehicles which are moved through a conduit by air through sequential zones one, two and three.  Preferably, the zones are inclined downwardly towards downstream for aiding movement of the vehicles downstream by gravity.  Zone one is a storage zone which preferably has vents adjacent its upstream end and its downstream end for controlling the speed of movement of vehicles into zone one and from zone one to zone two.  Zone two is the processing zone which receives vehicles from zone one and releases the vehicles to zone three.  Zone two includes an air blocking vehicle stop at its downstream end against which a first vehicle is held, and includes a holding arm which holds a second vehicle while the leading first vehicle is released.  The first vehicle is released to zone three, but only when zone three is clear of vehicles and a second vehicle is positioned behind the first vehicle.  Thereafter, the second vehicle is released and moves to the downstream end of zone two and becomes the leading vehicle for continuing the cycle.  Additional vehicles moving through the conduit are decelerated in zones one and two with the aid of air trapped behind the air blocking vehicle stop and/or parked vehicles.  An accelerator may be provided in zone two for providing a rapid start of the leading vehicle from zone two into zone three.  Vehicle position sensors are positioned in the various zones for sensing the presence of vehicles and controlling the movement of the vehicles through the conduit.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus provide for the elimination of any net DC component from the transmission of binary data sequentially in successive clocked bit cells of a transmission channel wherein logical first bit states, e.g., O's, are normally transmitted as signal transitions relatively early in respective bit cells, preferably at cell edge, and logical second bit states, e.g., l's, are normally transmitted as signal transitions relatively late in respective bit cells, preferably at mid-cell, and any transition relatively early in a bit cell following a transition relatively late in the next preceding bit cell is suppressed.  The onset of a sequence of second bit states following a first bit state that might introduce a DC component into the transmitted signal with normal transmission is detected by counting first bit states and producing a first indicating signal when the count is of parity indicating such sequence, and in response to the first indicating signal, a current bit and an adjacent bit the transmission of signal transitions is modified from the onset of such sequence to eliminate any DC component.          Preferably, the possibly troublesome sequences are encoded by encoding pairs of second bit states by a single transition early in the first bit cell of the pair.
