Title: Toner control system and method for electrographic printing
Inventor: BOWERS HARRY
IPC: G03G15/00
Filed: 1993-01-26
Granted: 2002-09-10
Abstract: Toner control system and method for an electrographic printer in which toner is delivered from a reservoir to a toner fountain and there applied to an electro-statically charged sheet to form an image. The visual quality of the image is monitored, and toner concentrate is added to the toner in response to the monitored quality to increase the amount of pigment particles in the toner and thereby maintain a substantially constant image quality. The concentrate is added to the toner in a return line between the fountain and the reservoir in relatively small, predetermined amounts, and it is mixed before being added. In the disclosed embodiments, a test image is formed outside the main image on the sheet, and the brightness of one or more predetermined colors in the test image is monitored. This system and method are applicable both to monochrome images and to multicolor images.

Granted: 1996-05-21
Abstract: A tubular sand screen is made in one piece entirely of powdered metal slivers which are molded and sintered to form a metallurgically integral rigid tubular structure.    Aggregate  metal  particles,  for  example, stainless steel slivers, are bonded together by interatomic diffusion as a result of sintering the compacted slivers under  high  temperature  and  pressure  conditions.    The sintered metal sand screen performs the function of a conventional  prepack  assembly  as  well  as  the  screen function.  According to one aspect of the invention, the sintered metal screen is subjected to electropolishing to yield an effective porosity of  40-60 mesh,  with pores having an average pore size of 150 microns.  Most of the surface irregularities are removed by electropolishing, and very few nucleation sites remain where sand fines in the size range of 74 microns-100 microns can become captured or otherwise lodged to cause plugging of the screen.

Abstract: A microwave oven includes a cavity in which food is accommodated, a magnetron for generating microwaves, and a waveguide to supply microwaves generated from the magnetron into the cavity.  The waveguide has substantially a truncated cone configuration in which the cross sectional area at the cavity side is greater than the cross sectional area at the magnetron side, and an output antenna of the magnetron is disposed to project from the bottom of the waveguide at the magnetron side into the inner space of the waveguide.  The microwave oven further includes a flat radiation antenna fixed in the inner space of the waveguide around the output antenna of the magnetron while maintaining distances from the waveguide and the output antenna of the magnetron in which no spark is generated.  Therefore, the radiation area for emitting the microwaves is increased significantly to improve heating nonuniformity within the cavity.

Granted: 2000-11-07
Abstract: Digital signal processing techniques are used to synthesize a range of output frequencies locked to a non-pullable reference oscillator, and the synthesized output frequency is used in a slave low bandwidth phase-looked loop; by increasing digital resolution in a phase accumulation register, any desired resolution of output frequencies can be generated. The range of output frequencies is synthesized in such a way as to generate only high-frequency fitter, which can be easily filtered by follow-on, low-cost, relatively high bandwidth phase-locked loops which are typically needed for frequency multiplication in a given system. The magnitude of residual fitter is easily controlled by proper choice of the non-pullable oscillator reference frequency, the output frequency range to be synthesized and various other digital factors, such as divider ratios. Improved noise performance is achieved while still maintaining a wide pulling range of the composite phase-locked loop.
