Title: Closed end fuel injection system
Inventor: HENSEL RICHARD J
IPC: F02D41/30
Filed: 1987-08-13
Granted: 1991-01-02
Abstract: ABSTRACT A marine fuel supply system for a fuel in-jected engine deadheads a high pressure fuel line with a closed-end connection to the fuel injectors without a recirculating return fuel line to the fuel injection pump and without a return fuel line to the remote fuel tank.  A differential pressure transducer senses differential pressure across the fuel injector between the high pressure fuel line and the low pres-sure induction manifold and turns off the fuel pump above a first value of relative differential pressure and turns on fuel pump at a second value below the first value, to maintain the fuel pressure in the high pres-sure line within a given range relative to induc-tion manifold pressure.

Title: Dispenser-applicator for spreading substances
Inventor: WILLCOX NANCY A
IPC: B05C17/00
Filed: 1988-05-16
Granted: 1992-08-18
Abstract: ABSTRACT OF THE DISCLOSURE An applicator  adapted  for storing and  spreading pre-measured portions of liquid, gel, creamy, low-melting semi-solid or solid substances on surfaces is disclosed. The applicator has a rigid base and a thin flexible cover attached to one side of the base to form, together with the base, a collapsible pocket for storing the substance.  A handle is attached to the other side of the base.  The thin, flexible cover includes one or more apertures wherethrough the substance contained in the pocket may flow out of the pocket.  A protective sealing member, such as a thin film, is removably attached to the exterior of the flexible cover to seal or protect the apertures until the sealing member is removed from the cover.  The flexible cover collapses as the substance is squeezed out of the pocket while it is being applied to a desired surface.  When the substance contained in the applicator is a low-melting solid or semi-solid, the substance melts or becomes flowable as it comes into contact with a warm surface on which the substance is to be spread.

Abstract: An improved circuit board material having a support layer, an electrical resistance layer and a conductive layer.  The circuit board material has a resistance of at least about 500 ohms/square.  The circuit board material is formed by electro-plating the electrical resistance layer on the conductive layer. The conductive layer is desirably activated prior to electro-deposition of the electrical resistance layer thereon.  The conductive layer is activated by contacting with an activating agent such as benzotriazole electrolytic chromate and the like.  A preferred electro-plating bath for electro-deposition of the electrical resistance layer comprises about 0.5 mole per liters nickel hypophosphite. The disclosed electro-plating bath functions at ambient temperatures and is effectively temperature independent.  Circuit boards can be formed from the circuit board material through a process involving only two etching steps.

Title: Method for transmitting digital data
Inventor: KANI TETSUO
IPC: G11B20/18
Filed: 1988-12-22
Granted: 1998-07-14
Abstract: ln a method for recording and/or reproducing digital data, such as digital audio signals recorded simultaneously with video signals, dividing sampling data composed of a plurality of bits into higher order bits and lower order bits, constituting error correction coding blocks by only the higher and lower order bits of the sampling data of a plurality of samples respectively, thereby making it possible to easily realize adaptive error checking in the course of the block-by-block error checking in association with, for example, data criticality. A sync word and a block address are affixed to the error correction coding block constituted in that manner. Since one block address is formed using the address data of two or more blocks, a broader address space can be obtained even when the bit number of the address area of each block is few. At least one flag bit(s) are provided in each sync word to use said flag bits in the blocks bearing specified block addresses as edit flags to set the edit flags in association with each edit point of digital signals, thereby facilitating discrimination of the editing points to reduce the rate of data discarding.

Filed: 1989-06-20
Granted: 1993-09-07
Abstract: ABSTRACT OF THE DISCLOSURE            The invention concerns a method and apparatus for measuring web tension. The tension of a moving web is measured by lo-cating close to the web (14) a gauging bar (1), which has its outer surface curved in the machine direction of the web (14) and carries pressure measurement sensors (2) in holes (3) formed into the bar. An air-cushion is formed between the moving web (14) and the curved surface, wherein the pressure is proportional to the tension of the web (14). The tension of the web (14) is measured in an indirect way by gauging the air-cushion pressure. The apparatus capable of implementing the method has an apparatus (7) required for the generation of a reference pressure, and the pressure measurement apparatus is used for measuring the pressure difference between said reference pressure and the air-cushion pressure.

Title: Ultrasonic grade and auger control
Inventor: MUSIL JOSEPH E
IPC: G01S15/88
Filed: 1989-09-13
Granted: 1994-06-07
Abstract: Abstract of the Disclosure An ultrasonic grade and auger control for use on a road paving machine to compensate for uneven road surfaces is described.  As the road paving machine travels, asphalt is centrally deposited along the road bed.  An auger is connected to the back of the road paving machine and contains a series of spiral blades which moves the asphalt away from the center of the road bed toward its outer edges.  The ultrasonic auger control apparatus detects the height of the asphalt positioned at the outer edges of the paving machine and regulates the speed of the auger to provide even distribution of the asphalt.  A screed is located behind the auger to uniformly place and pack the paving material.  The ultrasonic grade control apparatus regulates hydraulic actuators which control the thickness of the new road surface by adjusting the height of the screed.
