Title: Multiple Function Encoder Wheel for Cartridges Utilized in an Electrophotographic Output Device
Inventor: BARRY RAYMOND JAY
IPC: G03G15/08
Filed: 1997-02-14
Abstract: .:     Disclosed is a cartridge having an encoder wheel thereon for encoding EP supply cartridge characteristic information for an electrophotographic machine, the cartridge comprising, a sump for carrying an initial amount of toner.  A shaft is mounted for rotation in said sump, and an agitator or paddle is mounted thereon in such a manner that when the shaft rotates, the paddle rotates into, through and out of engagement with toner carried by the sump.  A single encoder wheel is mounted on the shaft, external of the sump, the encoder wheel positioned for proximate mating coaction with a coded wheel reader when the cartridge is mounted in position in the electrophotographic machine.  A drive means, and a variable torque flexible coupling connects the drive means to the shaft to effect rotation thereof.  The encoder wheel is configured for indicating, in conjunction with said coded wheel reader, a component of resistance to paddle movement through the portion of said sump having toner therein to give an indication of the amount of toner remaining in said sump. Other portions of the wheel, in a portion thereof which confronts the reader during a substantially constant velocity of rotation thereof, carries additional characteristics information of the cartridge to permit proper operation of the machine as well as increased efficiency of operation thereof.
Patent CA-2198990-A1 (CA)
Title: Diamond detection
Inventor: HAMM ROBERT
IPC: B07C5/34
Filed: 1997-03-03
Abstract: The invention concerns a method of detecting the presence of diamond in a body. In method the body is irradiated with a fast neutron beam modulated between first and second, distinct energy levels which are respectively resonant and non-resonant energy levels for diamond. Corresponding first and second absorption images are obtained for the body and from these images, a third absorption image is derived in which absorption effects attributable to the presence of non-diamond material in the body are eliminated or at least reduced. The resulting image is then analysed for the presence of diamond in the body. The energy modulated fast neutron beam is produced by nuclear reaction between an energy modulated particle beam and a target. The energy modulated particle beam itself is produced by a procedure in which a particle beam is passed sequentially through first and second particle accelerators in series. Modulation is achieved by operating the second particle accelerator alternately in first and second modes to produce, from the particle beam delivered by the first particle accelerator, a particle beam which is modulated between relatively high and relatively low energy levels.

Title: Temperature stabilized oscillator and proximity switch containing the oscillator
Inventor: HEIMLICHER PETER
IPC: H03B7/02
Filed: 1997-05-23
Abstract: In an oscillator comprising a resonant circuit (L, C, RCu) and an amplifier circuit  (V,  R1,  R2,  R3)  connected as a negative resistance (Rn), a direct current source  (I1)  is connected in series with the resonant circuit (L, C, RCU). In this way, a signal (Ucu) is provided being a measure for the resistance of the oscillator circuit coil (L).  By using this signal (Ucu), a control circuit (V1, M; V2, V3, M) controls  the negative  resistance  (Rn)  inversely proportional to the resistance  (RCU)  of the oscillator circuit coil (L).  This affords a simple stabilization of the temperature behavior of the oscillator circuit (L, C, RCu) and allows  the  low price manufacture of  inductive proximity switches having a great switching distance which function safely in a broad temperature range.

Title: Enhanced removal of hydrophobic contaminants from water clarification systems
Inventor: WILKINS LINDA S
IPC: D21C5/02
Filed: 1997-08-19
Abstract: The present invention provides a method for removing secondary fiber contaminants from paper mill process waters comprising adding a polyvinyl chloride, a cationic polymeric coagulant and a polymeric flocculant to paper mill process waters containing secondary fiber contaminants in an amount sufficient to agglomerate the secondary fiber contaminants to larger particles sizes, and removing the secondary fiber contaminants from the process water by a dissolved air flotation clarification technique. The addition of particulate polyvinyl chloride in combination with a polymeric coagulant and flocculant prior to the DAF clarification process causes the contaminants to become preferentially coated with the polyvinyl chloride particles. This coating is what causes the subsequent removal of the secondary fiber contaminants in the DAF clarification process to be more effective.

Abstract: A pulp refining and bleaching process for increasing the pulp brightness of a mechanical wood pulp prepared from softwood chips wherein the pulp is treated in one or more stages in refiner by adding sodium perborate or peracetic acid generated in a bleach generating unit by reacting sodium perborate or hydrogen peroxide with an activating agent such as tetraacetylethylenediamine in the presence or absence of caustic solution and the pulp discharged from the refiner is subjected to another bleaching stage in a bleach tower by separate addition of sodium perborate or hydrogen peroxide with or without a bleach activator. The process is preferably carried out by passing the pulp through a primary refiner at elevated pressure and optionally to a bleaching tower, a solution of sodium perborate or in-situ generated peracetic acid from a mixture of sodium perborate or hydrogen peroxide and an activator, tetraacetylethylenediamine being fed in the refiner and sodium perborate or hydrogen peroxide with an activator, tetraacetylethylenediamine, being fed in the bleaching tower.

Title: Local autoadaptive optical sensor
Inventor: LULE TAREK
IPC: H04N3/15
Filed: 1997-09-27
Abstract: The dynamics of the usual image sensors are not sufficient to process the brightness contrasts occurring in many situations.  Previously disclosed methods of increasing the dynamics have considerable disadvantages for practical application. Image sensors according to the new method should combine high dynamics with simple applicability.  To avoid the overexposure and underexposure of pixels which occurs with high image contrasts, each pixel contains a local autoadaptive control. With the help of this control, each pixel automatically ends its integration period as soon as it has integrated enough photoelectric current. An analog signal represents the length of the integration period selected by the pixel. Together with the integrated pixel signal, it represents brightness information with high dynamics and with low requirements regarding the dynamics of the individual signals.  Because of their local adaptivity, the image sensors are suitable for all applications where high brightness contrasts must be processed, such as guiding a motor vehicle in highway traffic, nature films and astronomy.
