Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates to an improved method of manufacturing a concrete manhole casing, manhole safety steps, and plugs for use therewith.  The method includes fabricating a form for the manhole of a predetermined shape and size, and securing a plurality of retractable arbors on the inside surface of the form, each arbor located at a pre-determined position.  The arbors are extended through the form and a sealed plug is placed on the end of the arbor.  The concrete is poured, vibrated and compacted and then the arbors are retracted leaving the sealed plugs in place. The plugs having a threading on the outside and a novel locking structure on the inside which securely locks the arm of a manhole step there to provide an excellent and secure hold.  The seal keeps the plug free from debris until ready to use.   The process provides an efficient method of forming a manhole using the novel plug.

Abstract: Case 7-12154/GTS 440 A PROCESS FOR ASSESSING THE QUALITY OF A  PRINTED PRODUCT                  ABSTRACT         The differences between the scanned values of corresponding image points of a specimen and an original are formed by point-by-point scanning and comparison with an original.  The difference values are subjected to a tone or shade correction, and then a weighting process and a minimum threshold correction.  In the shade or tone correction, a mean value formed from the difference values in a specific surrounding area of the associated image point is subtracted from each difference value.  The weighting process is effected individually for each image point and results in systematic errors and critical image zones not producing faulty assessments.  The weighting factors are determined by statistical analysis of specimens which are assessed as good visually.  The minimum threshold correction eliminates all those pre-treated difference values which are below a certain minimum threshold.  The difference values of the points surrounding each image point are added algebraically with distance-dependent weighting to the remaining difference values of each image point.  The resulting values are compared with a threshold value for each image point.  If these values exceed the threshold value at least at one image point, the specimen is assessed as faulty.

Abstract: SPEED ADAPTIVE CONVEYOR DRIVE FOR  A GLASS MANUFACTURING SYSTEM                      ABSTRACT          A conveyor drive for a glass manufacturing system transports a sheet of glass through a tempering station on a roller bed.  The conveyor drive includes a pair of pulleys mounted at opposed ends of the tempering station.  A continuous drive loop is trained over the pair of pulleys and engages the roller bed so that rotational motion of the pulleys is imparted to the rol-ler bed.  One pulley is driven by a motor to transport the glass through the station.  The other pulley drives an electrical generator connected to a dissipative load. The generator and load provide an adaptive counter-torque to the other pulley in direct relation to its rotational speed.  The counter-torque stabilizes the con-veyor drive to prevent slip-stick friction from dis-rupting the transport of the glass sheet.

Abstract: SINGLE FREQUENCY TONE RECEIVER          Abstract of the Disclosure A tone receiver indicates the presence of a PCM tone signal in a bit stream of PCM signal samples.  Predetermined characteristics in a consecutive series of PCM signal samples are used to define an interval which begins in response to at least two consecutive ones of the PCM samples being received which are of one polarity and meet a magnitude threshold.  The interval ends after at least two more consecutive ones of the PCM samples are received and are of the other polarity and meet a magnitude threshold.  The presence of the tone signal is detected when the number of PCM signal samples received during the interval is within a predetermined range and the number of polarity changes in the PCM signal samples is less than a predetermined number.  In one arrangement, the tone is indicated as having been received only after it has been detected at least a minimum number of times in a plurality of interval occurrences.                            - i -

Each furnace is so designed that by the combined use of a glow discharge and a heating element (installed between an outer wall and an inner shielding wall of each furnace) workpieces are heated and nitrided at high efficiency with stable discharge, uniform temperature dis-tribution and in a short time.  The plural furnaces use a common D.C. power source which is switched between the furnaces for alternately generating a glow discharge in each furnace.  The heating elements can be individually energised or can also have a common A.C. power source that is switched to alternate between them.  The result is a minimisation of equipment for a maximisation of output.
