Abstract: A chordal keyboard method and apparatus for generating a key code using a plurality of keys (301) coupled to a controller (302) with a first and second set of registers (303, 304). A user depresses (201) at least one of the keys (301). The controller (302) detects (202), which of the keys (301) are in a depressed position and which of the keys (301) are released from the depressed position. The controller (302) sets (203) in the first and the second set of registers (303, 304), bit locations of respective depressed keys, and clears in the second set of registers (304) bit locations of respective released keys. When the controller (302) detects (207) that all keys (301) are in a released position, a key code is generated (209) corresponding to bit locations set in the first set of registers (303). Then, the controller (302) clears (210) the first set of registers (304).

Title: Cutter assembly
Inventor: OBER FRANK
IPC: B26D1/18
Filed: 1993-11-03
Granted: 1996-07-09
Abstract: A cutter assembly for cutting sheets of relatively thin material is disclosed. The cutter assembly comprises a base member, a pair of support posts securely attached to the base member, and an elongated guide rail having a first end and a second end supported by the support posts in laterally spaced relation to the base member.  A cutting strip is securely retained by the base member for receiving the sheets of material thereon.  There is a cutter head slidably mounted on the elongated guide rail, and a cutting wheel operatively retained in rotatable relation by the cutter head.  A spring biasing means biases the cutting wheel toward the cutting strip such that the cutting wheel is received in intimately contacting relation against the cutting strip.  The cutting wheel moves along the elongated guide rail so as to intimately contact the cutting strip along the length thereof, so as to thereby permit cutting of the sheets of material when they are between the cutting wheel and the cutting strip. A spring member is disposed between upper and lower members of the base member so as to camber the upper member to match the bowing of the elongated guide rail that occurs as the cutting wheel moves along the elongated guide rail and therefore along cutting strip to cut the sheets of material.

Filed: 1993-12-20
Granted: 2001-04-17
Abstract: ABSTRACT     A method for forming a stable emulsion of a viscous hydrocarbon in an aqueous buffer solution includes the steps of: providing a viscous hydrocarbon containing an inactive natural surfactant and having a salt content by weight of less than or equal to about 15ppm and having a water content by weight of less than or equal to about 0.1%; forming a solution of a buffer additive in an aqueous solution to provide a basic aqueous buffer solution, the buffer additive being operative to extract and activate the inactive natural surfactant from the viscous hydrocarbon; and mixing the viscous hydrocarbon with the aqueous buffer solution at a rate sufficient to provide an emulsion of the viscous hydrocarbon in the aqueous buffer solution, whereby the buffer additive extracts the inactive natural surfactant from the viscous hydrocarbon into the aqueous buffer solution and activates the inactive natural surfactant so as to stabilize the emulsion.  According to the invention, the buffer additive is a water soluble amine.  The inactive natural surfactant contained in the viscous hydrocarbon includes carboxylic acids, phenols, esters, and mixtures thereof.  Bimodal emulsions, having two distinct droplet size distributions, are also formed according to the method of the present invention and have improved viscosity characteristics.

Abstract: The present invention provides real time call control within a telecommunications network, using a call selection processor separate from the switches carrying the call, which responds to incoming calls and uses information carried in the associated signaling messages to determine what application processor, if any, should be involved on the call. One embodiment of the present invention includes a call selection processor called a signaling director" or "SD" for short, for recognizing certain signaling messages, typically SS7 initial address messages (IAM's), as the messages flow through the signaling network. Alternatively, particular signaling messages may be recognized in a signaling message processing element within the signaling network, such as the signal transfer point (STP) associated with the switch that receives the telephone calls, and a copy of those particular messages forwarded to the SD.

Abstract: A reignition device (32) for a gas burner includes a reig-nition flame chamber (31) which opens into a burner face of the gas burner. The burner face is also provided with a plurality of circumferentially spaced burner ports (28, 29). The reignition chamber (31) includes at least one port (98) for receiving an air/gas mixture flowing within the burner head. A reignition flame is initially ignited at the reignition chamber by a burner port flame or an electrode (47) which also can be used to ignite the gas flowing out of the various burner ports (28, 29) in the burner face. The reignition device (32) is designed so that the reignition flame burns in a balanced and stable manner both when the burner is set at a high rate and when the gas burner is turned down to a low setting. Subsequently, should the flames about the burner face be extinguished by an external influence, the reignition flame will remain ignited and will function to reignite the burner flame.

Title: Adjustable wing plow
Inventor: NIEMELA CAL G
IPC: E01H5/04
Filed: 1996-09-05
Granted: 2007-07-24
Abstract: A plow assembly is disclosed for vehicles such as pickup trucks and tractors for moving snow or other materials. The plow assembly has at least one extendable, forwardly pivotable plow wing which is extendable on one end of a main plow by sliding movement along the front of the plow between a retracted and an extended position in which the plow wing is generally aligned with the plow front surface. The plow wing is also pivotally mounted on a hinge for movement between the extended position and a forwardly angled position in which the plow wing front surface extends at an angle to the plow front surface. A power source connected to the plow wing is operable to move the wing between the retracted, extended and forwardly angled positions. Preferably, a latch assembly prevents pivotal movement of the plow wing to the forwardly angled position until the plow wing is in the extended position. In the preferred embodiment, an extendable plow wing is included on each end of the main plow with a pair of independent fluid cylinders connected to the respective plow wings which are operable independently of one another to move the plow wings independently between their respective retracted, extended and forwardly angled positions. When both plow wings are pivoted to their forwardly angled positions, the plow assembly has a general U-shape which facilitates pushing snow or other material without the snow slipping off the plow blade ends. The plow assembly is also preferably pivotally mounted on a support frame for movement about a generally vertical pivot axis from a centered position to a series of angled positions in which the plow blade is angled to the left or right of the centered position. If desired, the plow blade may be pivotally connected to the support frame about a second, generally horizontal pivot axis to allow forward pivotal movement of the plow blade and plow wings in unison when the plow blade or either wing encounters an obstacle during plowing.
