Abstract: ABSTRACT          A hydraulically dampened rubber support includes a load bearing support, an annular spring element of elastic rubber material and a support base, which together enclose a working chamber and a compensation chamber. These chambers are connected through a first damping passage.  The working chamber, the compensation chamber and the damping passage are filled with liquid.  The spring element has at least two spring sections in the shape of hollow cones arrange symmetrically to a plane which extends transversely to the axis of movement.  The spring sections are secured with their adjacent ends to a rigid connecting element which defines a second damping passage.

Abstract: A method  and  system  for  color  and  monochromatic printing wherein ordered dither and error diffusion processes are combined to provide high quality printed images with good spatial resolution,  good gray scale transitions,  good low frequency  and  high  frequency  responses  and  a  high computational speed.  Using this process, gray scale numbers representative a of scanned image are summed for each super pixel of the scanned image and divided by a chosen gray level normalizing factor. This division operation is done to obtain a normalized ordered dither quotient number of drops (dots) to be printed in super pixels and to further obtain an error remainder number of dots to be dispersed to surrounding super pixels.  The normalized ordered dither quotient number of dots are printed in pre-assigned individual pixels within printed super pixels, and the error remainder number of drops are diffused to other pre-assigned surrounding or adjacent super pixels.  In this manner, a combination of ordered dither and error diffusion signal processing and printing is achieved to simultaneously  take  advantage  of  some  of  the  best characteristics of both types of signal processing printing.       In color printing, the above operation is carried out in each of a plurality of separate color planes, and all of the  quotient  information  is  retained  and  printed  in  a predetermined priority sequence for each color plane.  Thus, this invention is not only operative to retain the maximum amount of image data for each color plane, but it is printed in an output matrix of super pixels in such a manner as to maximize overall print quality of the reproduced color image.

Patent CA-2028707-A1 (CA)
Inventor: FRANKLIN GENE R
IPC: G06K9/00
Filed: 1990-10-29
Abstract: A method for locating the start of a MICR character in E13B font so as to facilitate character recognition.  A Calculated Character Start Position (CCSP) is generated by using a predetermined number of voltage samples corresponding to a portion of MICR waveform generated by reading a MICR character on a document.  The CCSP is generated by averaging the predetermined number of voltage samples within the window which tends to minimize the harmful effects of noise.  Noise from magnetic ink spatter is sometimes wrongly interpreted as the start of a character.  A process of "jiggling" is used to assist character recognition techniques by utilizing different character start positions to determine whether or not a template match in character recognition techniques occurs when the new or different character start position is used.  Dynamic thresholding is used to avoid false starts or "ringing" due to an immediately previous character which was read having a high intensity waveform compared to the normal intensity expected.  The method also employs a technique of having a variable starting point for the search for the start of the next character, with the variable starting point being based on the character just recognized.

Abstract: An ink jet printhead is fabricated with a resistive temperature sensor formed adjacent to the heater resistors and, in a preferred embodiment, of the same material. Temperature sensing variations between a plurality of printheads used in the same printer is achieved by trimming the thermistors to the desired resistance value while holding the printhead at the nominal set temperature. In one embodiment, the heater resistor and thermistor are formed within the same polysilicon layer, and the resistor trimmed therein. In a second embodiment, a thick or thin film resistor is formed or bonded in series with the polysilicon thermistor with the trimming being accomplished at the thick, or thin film resistor.
Patent CA-2029927-A1 (CA)
Title: Drill assembly
Inventor: MARIC MILAN
IPC: E21B10/00
Filed: 1990-11-14
Abstract: Drill tools with eccentric bits for drilling a hole having a large diameter generally include a bit for swinging out to an eccentric position for drilling, and for swinging into a non-eccentric position for removal from a tubular casing.  Relatively complicated structures are required for effecting bit movement, and it is often difficult to remove the bit for replacement or repair.  A drill assembly offering a solution to both problems includes a mandrel for rotatable mounting in a tubular casing, a bit rotatably mounted in the mandrel, the bit and mandrel normally rotating together in one direction with the bit eccentric with respect to the mandrel, whereby the bit can bore a hole larger in diameter than the casing, a head on the bit for engaging a formation to stop rotation of the bit, shoulders on the bit and mandrel for retaining the bit in the eccentric drilling position, an inclined cam surface on the bit for engaging the bottom of the casing when the bit is moved upwardly to cause the bit to rotate in the other direction (opposite to the drilling direction) to a release position in which the bit is aligned with the casing for movement therethrough, and second shoulders on the mandrel and bit for limiting rotation of the bit to the release position.  The shoulders on the mandrel and bit are in the forms of projections which overlap in the vertical direction, each projection defining approximately one-quarter of the cylinder for rotation between the bit extended and the bit retracted positions.

Title: Valve pump
Inventor: FIEDLER ROBERT R
IPC: F04F1/08
Filed: 1991-05-20
Abstract: VALVE PUMP          ABSTRACT OF THE DISCLOSURE To provide smoother operation of a gas-operated purge pump, the pump housing receives a standpipe closed by a low-density,  floatable check valve element at the inlet of a standpipe within the housing.  Periodically, at timed intervals, air is forced through an air conduit into the housing.  If there is liquid in the housing, a check valve element floats upwardly because it is less dense than the liquid and mounted for movement to and away from the valve seat.  While it is off of the valve seat, the air forces water into the standpipe and it moves upwardly until the chamber of the tubular pump housing is free of the liquid, at which time the check valve drops back into position and seats to prevent further flow of liquid.    Upon termination of the pumping of gas pressure, the check valve in the pump housing inlet is free to move under the pressure of water in the well and the pump housing chamber again fills with fluid, causing the valve element to lift and permitting flow of water into the standpipe.

Title: Method of preparing a catalyst component for the polymerization of olefins
Inventor: GAROFF THOMAS
IPC: C08F4/60
Filed: 1990-02-15
Abstract: Abstract The invention relates to a new method for preparing a suppor-ted procatalyst of a catalyst system intended for the polyme-rization of olefins, in which the reaction product formed from magnesium halogenide and an alcohol is treated in order to remove the alcohol and is activated with a transition metal compound and optionally an electron donor. In solutions of prior art the transition metal compound reacts with the alco-hol as well as with the magnesium chloride and additionally acts as a medium for separating the by-product formed of it self and the alcohol. The problem is then that great amounts of transition metal are wasted and that said by-product is a hazardous waste that is difficult to treat. These problems have been solved in the present invention by removing the al-cohol with the aid of a separate grinding-evaporation step. The grinding-evaporation step is preferably carried out by jet mills by using a temperature gradient for the gas.
