Title: Novel vi enhancing compositions and newtonian lube blends
Inventor: CHU ALICE S
IPC: C10N40/04
Filed: 1990-04-24
Abstract: A novel composition is disclosed that is particularly useful as a lubricant viscosity index improver. The composition comprises branched C30-C10000 hydrocarbons that have a branch ratio of less than 0.19 and viscosity at 100° C between 725 mm2/s and 15,000 mm2/s. The novel compositions comprise the product of the oligomerization of C6 to C20 alpha-olefin feedstock, or mixtures thereof, under oligomerization conditions at a temperature between -20° C and + 90°C in contact with a reduced valence state Group VIB metal catalyst on porous support. The compositions have viscosities at 100°C  between 725 mm2/s and 15,000 mm2-/s. Using the foregoing compositions in admixture with mineral oil and synthetic lubricants provides novel lubricant blends that show an elevated viscosity index. The mixtures also show an increased stability to shear stress at high temperature with all blends notable by exhibiting Newtonian flow.

Title: Carrier web transfer device and method for electrophotographic printing press
Inventor: KUBERT VINCENT T
IPC: G03G15/16
Filed: 1990-12-07
Abstract: Abstract A transfer mechanism and method are provided for utilization in a high speed electrophotographic printing process of the type wherein the electrophotoconductive cylinder on which the image is formed travels at a peripheral speed of at least 100 ft./min.  Transfer of the image is made to a continuous web of paper or the like travelling synchronously with the cylinder surface speed. A transfer corona focuses a narrow band of ions proximate the cylinder-web interface to attract at least 95% of the solids, toner particles from the cylinder to the travelling web.  The charge on the transfer corona exceeds the charge on the image portions of the rotating cylinder by at least about 5,000 volts.

Abstract: For fulling, the mineral fiber sheets (11) are moved in the direction of the arrow by means of two endless studded belts, only the lower one (15) of which is visible in the drawing.  By means of the first fulling tool (29), pre-fulling to a depth of about 8 cm is effected.  With the second fulling tool (30), fulling to a depth of about 11 cm is effected.  During the fulling process, the region of the mineral fiber sheet (11) not belonging to the fulling zone is supported on the bottom and top, so that a change in the fibrous structure of the material takes place only in the peripheral region that subsequently forms a compressible zone (23).  The fulling is done from the side, or in other words in the same direction as the later compression upon installation of the mineral fiber sheet between two rafters.  To prevent sagging of the mineral fiber sheet (11) during the fulling process, guides, only the lower guide (27) of which is visible, are disposed in the region of the fulling zone above and below the mineral fiber sheet.        Each fulling tool (29, 30) comprises a plunger (32) with a cylindrically curved surface (31), over which an endless belt (37) is guided.  The belt travels at practically twice the speed of the mineral fiber sheet (11).  During the passage of the mineral fiber sheet (11), the plunger (32), driven by the crank drive mechanism (43), executes a number of pivoting motions about the pivot shaft (41).

Title: Engine speed limiter
Inventor: FIORENZA JOHN A II
IPC: F02P11/02
Filed: 1991-02-08
Abstract: ABSTRACT An engine speed limiter includes a computing means for computing a value that is functionally related to the time between successive ignition pulses and for outputting a speed signal representative thereof.  The speed limiter also includes generating means for generating a reference signal that is functionally related to the desired maximum limit speed.  A comparison means compares the speed signal with the reference signal and generates a limit signal if the result of the comparison indicates that the actual engine speed is about equal to or greater than the desired maximum limit speed.  The limit signal is used to interrupt engine ignition to thereby limit engine speed.

Title: Method and circuit for hid lamp starting
Inventor: BYSZEWSKI WOJCIECH W
IPC: H05B41/231
Filed: 1991-05-23
Abstract: METHOD AND CIRCUIT FOR IMPROVED HID LAMP STARTING    Abstract In one aspect of the present invention a capacitor is placed in series with the ballast and the lamp.  The capacitor lowers the impedance during lamp starting and is shorted out when final arc conditions of the lamp are reached.   Method and device for improvement of lumen maintenance of high intensity discharge lamps through minimizing the wall blackening during lamp starting is disclosed.  Reducing the electrode material sputtering during the thermionic arc phase of the lamp starting process was achieved by decreasing the cathode fall voltage.  The cathode fall voltage in these lamps was decreased by increasing the current flowing through during the starting phase.  The increase of starting current was achieved by increasing the open circuit voltage or by decreasing ballast impedance.

Title: Fuel combustion system and method of operation for an otto-cycle internal combustion engine
Inventor: BAILEY JOHN M
IPC: F02B19/12
Filed: 1990-02-12
Abstract: A fuel combustion system (12) for an Otto-cycle internal combustion engine (10) including a main combustion chamber (14) and an auxiliairy combustion chamber (26). Timing of ignition is effected by opening a control valve device (28) during a latter portion of the compression phase which permits a pressurized combustible mixture (18) to flow from the main combustion chamber (14) and into the auxiliary combustion chamber (26) where the combustible mixture therein is ignited. Hot burning gases emanating from the auxiliary combustion chamber (26) through a suitable directing device (32) provide single or multiple and penetrating sources of ignition for the bulk of the combustible mixture (18) present in the main combustion chamber (14). This arrangement provides a very reliable and long life ignition system for Otto-cycle engines and is especially advantageous for engines which burn a relatively lean combustible mixture.

Patent CA-2060711-A1 (CA)
Inventor: FARR JAMES B
IPC: F25D29/00
Filed: 1992-02-05
Abstract: The present invention is a cold control for refrigerators.  The cold control circuit includes temperature sensitive resistances disposed within the cold box portion of the refrigerator.  The cold control circuit senses the temperature of the cold box portion by a NTC thermistor which is disposed in the cold box portion and connected to the control circuit.  When the temperature rises above the turn-on set point, the NTC thermistor has a relatively small resistance and activates a transistor.  The transistor is connected to a latching circuit which maintains activation of the refrigerator until the thermistor falls below the turn-off point.  Another solid state switch of the control circuit activates the refrigerator com-pressor, such as a transistor turning on an inverter in a DC powered refrigerator and a triac directly supplying current in an AC powered refrigerator.  For battery powered refrigerators, the cold control includes a clipping circuit to prevent false activation or de-activation of the inverter caused by ripple voltages.  The present invention provides the reliability of a solid state temperature sensor while avoiding the expense of a microprocessor driven system.

Abstract: ABSTRACT       A method of forming a catamenial tampon is disclosed which is capable of absorbing menstrual fluids.  The method includes the steps of starting with an absorbent having a cross-sectional area of varying thickness.  The thickest portion has a greater volume of fibers than the thinnest portion.  The absorbent can be optionally enclosed with a cover. An opening is formed through the absorbent and/or the cover and a withdrawal string is secured thereto.  The absorbent is formed into a generally elongated, cylindrically shaped blank and then is compressed into a pledget having a zone of high density fibers and a zone of low density fibers.  After compression, the zone of low density fibers will expand faster and/or to a greater extent than the zone of high density fibers, thereby forming a curved tampon.  The curved tampon is rigid and self sustaining and can be used as either a digital tampon or with an applicator.
