摘要： A top vacuum corrugation feeder employs a vacuum feedhead working in conjunction with an air knife to feed sheets from the top of a stack. The air knife employs a thick boundary layer of air at a low pressure to suspend and separate the sheets by aerodynamic drag, resulting in about a 50% reduction in the required power for operation of conventional top vacuum corrugation feeders.

摘要： A stylus which includes a conductive blank and at least three conductive wires soldered onto the blank to form the writing tip of the stylus. The wires are placed parallel to each other and the tip ends thereof are so aligned that they form a line transverse to the direction of the travel of the stylus as it travels over a recording medium. The wires are preferably bonded to each other and held in a predetermined spatial relationship by a cured epoxy resin.

摘要： An electrostatographic imaging device of the type forming a multilevel electrostatic latent image on a surface of the imaging member (10), and developing (33, 34) the multilevel electrostatic latent image with at least two types of toner, includes a brush cleaner (F) for removal of toner and debris remaining after transfer of the image to another surface. The brush cleaner is maintained in a condition loaded with a first toner type providing abrasive characteristics at the fibers of the brush, for abrading the imaging member for removal of toner of said second type.

摘要： In copying or printing, proper printed copy sheets generated from the printing operation may be selectably operator directed to various different copy sheet output compiling stations, such as a stacking tray or a finisher compiler. Those copy sheets desired to be purged rather than provided as finished copies {called purge sheets below} are directed to a particlar designated such station for operator removal and disposal. Preferably this designated purge station is a readily operator accessible existing top tray. In this system, reduced printing delays are provided by continuing the printing process as long as the proper copy sheets are selectably directed to a copy sheet output compiling station which is not the same tray or station into which the purge sheets have been directed in the same printing operation, or, as long as the proper copy sheets will not be stacked on top of the purge sheets in that same tray. The printing operation of the copy sheets is automatically stopped to prevent such intermixing of the purged sheets with the proper copy sheets in the same output tray. However, this interrupted printing operation can then resume in response to sensing that all the sheets in that tray have been removed, which may be directed.

摘要： Disclosed is a process for removing contaminants from a contaminated area of the ground having a vadose zone (16) and a water table (18). The process comprises providing a borehole (42) in the contaminated area; placing in the borehole a perforated riser pipe (44) inside of which is situated a vacuum extraction pipe (30) with an opening situated near, at, or at any point below the water table within the perforated riser pipe; while introducing a gas into the riser pipe, applying a vacuum to the vacuum extraction pipe to draw gases and liquid from the soil into the perforated riser pipe and from the riser pipe into the vacuum extraction pipe and transport both the gases and the liquid to the surface as a common stream; forming from the common stream a stream which is primarily liquid and a stream which is primarily gaseous; and separately treating the separated liquid and gas streams. Also disclosed is an apparatus for carrying out the process.

摘要： A multichannel ADC is fabricated on a single chip with each analog channel (10) for concurrently processing input analogue signals in a pipelined manner, and including a dual-purpose intermediate amplifier (14) for amplifying an input voltage to be converted, and providing a reference voltage for use during conversion. A capacitor array is used which reduces the area required to implement the convertors.

摘要： 1345391 Electro-photography XEROX CORP 17 May 1971 [20 May 1970] 15329/71 Heading G2H In a subtractive multi-colour registered transfer process using impure light filters, a developed image corresponding to a pure colour is produced at each stage by employing a development electrode at a potential between a high potential corresponding to the pure colour and a lower potential corresponding to other colours transmitted by the filter. The development electrode potential may be 20 volts above the said lower potential. A line-by-line image of a stationary object, corresponding to a particular colour, may be projected on to a charged photoconductive drum 10 using a moving lens system comprising illumination lamps 18 and filter 20, the resulting charge image being developed at one of a plurality of magnetic developer stations 21-23 and transferred to a sheet 100. Each developer station comprises a pair 80 of rotary cylinders, each containing a stationary magnetic 81 and being connected to a source of potential Fig.7 (not shown). In the complete multistage process, the filters are changed automatically by means of a solenoid.
