Abstract: A descaling method for removing oxide scale from a hot-rolled stainless steel comprising the steps of: applying a solution of an alkaline earth metal chloride to the surface of the oxide scale layer formed on the hot-rolled stainless steel strip, and allowing the solution to penetrate into the oxide scale layer.  In a subsequent annealing, the solution is heated and dehydrated to become solid matter and the dehydrated matter is melted and diffused into the oxide scale layer to soften the oxide scale layer.  The oxide scale layer is then removed by a simple mechanical descaling by, for example, grinding brushes with or without a subsequent chemical descaling by a weak acid solution.

Filed: 1991-06-17
Granted: 1999-11-09
Abstract: An air freshener dispenser includes a two-part housing including a base and a separable cover. The base carries a control circuit and the cover carries a dispensing blower and a replaceable cartridge including the freshening agent to be dispensed and a battery for powering the blower. When the cover is removed from the base the blower is connected directly across the battery for test purposes, but when it is mounted on the base, contact structure on the cover and the base cooperate so that the blower is connected to the battery through the control circuit and is controlled thereby. The control circuit turns off the blower and triggers visible and audible alarm signals after a predetermined time period and/or when the battery voltage gets too low. A photocell turns off the blower and disables the audible alarm in the dark. The time-out period of the timer is selectively changeable.

Abstract: A hand operated automobile brake and accelerator operation assembly for the handicapped can be readily transferred from car to car without tools and is adaptable to various models of cars.  It is installed by clamping onto the brake pedal shaft with manually operable wing nuts or the like as the sole fixed connecting bracket on the car.  The brake pedal and accelerator pedals are respectively operated by pushing and pulling by hand an operating rod to move an operating lever fulcrumed on a pivot axis fixed relative to the brake pedal shaft.  This operating lever moves an accelerator operating shaft into contact with the accelerator pedal to depress it as the hand operated rod is pulled. Conversely when pushed the hand operated rod depresses the brake pedal and release the accelerator.  To accommodate different car models an accelerator operating shaft has a manually operated lock to fix its length, and the accelerator assembly distance from the brake is adjustable.  Thus the assembly can be installed and changed from car to car with few or no tools.

Abstract: A flat and nearly mechanically isotropic liquid crystal polymer film (38) can be formed by laminating two biaxially oriented films. A laminate is produced having two thin outer surface portions which are oriented in one direction and a relatively thick inner portion. The film is formed by passing a polymer through a set of three tubular rotors (30) which are concentric and have facing surface which define inner and outer annular polymer flow channels. These rotors may rotate in the same or opposite direction of the flow. Another way to make the film is with a slit-type die (90) through which a polymer flows in one direction, while a moving band (91) passes continuously in a traverse direction. These ordered-polymer films are useful in the production of printed circuit boards.

IPC: F16H59/48
Filed: 1992-09-02
Granted: 1998-05-05
Abstract: In a system for controlling  a gear ratio of a multi-step geared or continuously variable automatic transmission of a vehicle, the gear ratio is determined through fuzzy production rules each having one of an ATF temperature, a steering or an engine coolant temperature.  For example, the rule regarding the ATF temperature defines such that the gear position should be shifted down if the ATF temperature is high.   With the arrangement, when the ATF temperature is high, the gear position is determined in the downshifting direction so that the amount of torque converter slippage can be reduced, whereby avoiding temperature rise in the transmission.  And since the engine speed is relatively high at that situation, motive force could be sufficient even climbing a hill.

Abstract: An apparatus and method for allowing television systems using solid-state image sensors to be compatible with a multiplicity oh television standards.     Scenes conforming to a standard which specifies a format aspect ratio or a specific number of active scan lines per frame are input into the anamorphic television system. The anamorphic television system modifies these scenes to take optimum advantage of the resolution of the solid-state image sensor. The anamorphic television system alters the dimensions of the scene along the horizontal and/or vertical axis so that the scene conforms to the format aspect ratio of the solid state image sensor and/or to the number of active scan lines per frame as specified in the applicable standard. The solid-state image sensor converts the optical information into an electrical signal. This electrical signal is retrieved from the solid-state image sensor by timing circuitry. The retrieved electrical information is converted into a composite video signal which is then displayed on the display monitor. The original proportionality of the scene is recaptured by altering the vertical and/or horizontal height controls on the display monitor and/or by altering the rate at which the information is retrieved from the image sensor and displayed on the display monitor.

Granted: 1998-07-28
Abstract: A flue gas scrubber for removing sulfur from flue gas.  This scrubber, whether a horizontal or a vertical scrubber and whether a dry or a semi-dry scrubber, incorporates a recycle line that separates heavier dry solid particles from the finer particles still  entrained  within  the  cleaned  flue  gas. This  recycle conduit then delivers these removed dry solid particles back to the scrubber for re-injection therein so as to reduce the drying time of the reagent slurry sprayed within the scrubber.   Such drying time is reduced by the recycle of these dry solids because of  the  increased  surface  area  overwhich  the  reagent  is  now sprayed.

Title: Polymerization reactor
Inventor: MCDONALD MICHAEL F JR
IPC: B01F27/91
Filed: 1992-07-17
Granted: 2001-05-29
Abstract: A novel chemical reactor; one particularly useful for the production of polymers, especially elastomers such as butyl rubber. The reactor (10) contains (1) a two-tube pass system, constituted of an inner or center tube bundle (20) through which a mixture or slurry of polymerizable monomers and catalyst is passed in one direction, and recycled via an outer tube bundle (30) in the opposite direction in essentially even flow distribution (2), while the tubes of the center and outer tubular bundles are maintained within a jacketed section, or sections of the reactor into which a coolant, or refrigerant; is injected and vaporized to remove the heat of reaction. The coolant, or refrigerant, in heat exchange relationship with the tubes removes the exothermic heats of reaction from the polymerization mixture, and maintains the polymerization mixture at uniformly low temperature. An even flow circulation of the slurry which aids in maintaining uniform low temperature, is provided by the use of (3) a diffuser (60) and (4) mixed flow pumping system (40), with its impeller (43), by virtue of which an adequate pressure head of even pressure profile is developed across the entry sides of the center tubes (20) to maintain the even flow distribution within the two-tube pass system at high circulation rate. There is no vortex whirl at the exit of the impeller-diffuser assembly, and no cavitation bubbles as commonly associated with one-tube pass systems, which employ a central draft tube and axial flow pump. Improved mixing, high hydraulic efficiency, and higher production rates with low polymer fouling, are achieved.

Granted: 2002-10-22
Abstract: Methods of starting a hydraulically-actuated electronical-ly-controlled fuel injection system (10) are disclosed. One meth-od comprises the steps of pressurizing actuating fluid used to actuate a unit injector (18) and actuating an electrical actuator assembly (36) of the unit injector (18) to cause fuel injection on-ly when the pressure of the actuating fluid is at least equal to a selected minimum level. This method of the present invention ensures that the unit injector (18) does not diminish the pres-sure of the actuating fluid until the pressure has reached a se-lected minimum level required to effect fuel injection. This method allows the pumping capacity of the high pressure actu-ating fluid pump (332) to be minimized while ensuring quick starting of an engine (12) by the fuel system (10).
