Abstract: FASTENER DRIVING TOOL                        Abstract A tool for driving uncollated nails includes a tool body with a nose portion defining a drive track wherein a driver blade moves in drive and return strokes.  A magazine carried by the body supports a row of nails, and a pusher urges the nails along a feed path toward the drive track.          The magazine is adjustable for tailoring the feed path width to the nail size.  Individual nails are advanced from the magazine to a drive position in the drive track by an escapement mechanism operated in timed relationship with the driver blade, and an advanced nail is held in the drive position by a magnet assembly supported by the tool nose portion.  Nails are positively advanced and are properly oriented by the escapement mechanism independently of the number of nails, the pusher force, or other conditions in the magazine.  The tool magazine is quickly and conveniently loaded with nails supplied in an oriented condition from a loading chute.  The loading operation is automatic in response to engagement of the magazine with the chute, and does not require awkward manipulation of the pusher.  Coupling members on the magazine and on the chute are mated by means of ramp and guide structures.          In the mated position, stops in the nail path are opened to permit nails to slide from the chute into the magazine.

Abstract: Cloth Spreading Method and Apparatus Abstract of the Disclosure A cloth spreading apparatus for use with an automatic cloth cutting machine.  The apparatus is used in conjunction with a movable cutting surface which conveys cloth to a cutting station.  The apparatus includes a  spreader frame which moves on rollers along track surfaces adjacent the cloth laying surface to deposit cloth on the stationary surface.  To provide this movement the spreader includes a direct current motor with an output coupled to the rollers.  The motor speed of rotation is monitored by control circuitry including a tachometer.     Mounted to the spreader is a cloth feed carriage which includes a cloth feed motor.  The relative speed of the drive motor and cloth feed motor are controlled by feedback circuitry coupled to a drive and feed tachometer. The angle of cloth deposition onto the cutting surface is monitored by a feeler gauge.  Whenever this angle deviates from an optimum value the speed of the cloth feed motor is automatically adjusted by circuitry coupled to the cloth roll motor.   In this way, tension of the cloth is optimized as it is dispensed onto the surface.

Abstract: ABSTRACT     This invention relates to an implant device with a body implantable connector.  It is well known in the art that these are various methods for externalizing an internal vessel, or providing fluid communication from the vascular system to a cleansing source outside the body.  In the former, the ulceration of the skin, and in the latter the trauma of connecting and reconnecting arteries and veins with tubes or needles have proved to be serious problems.          The present invention seeks to do away with these problems by pro-viding a body implantable connector to replace a portion of a patient's body fluid or solid carrying conduit and an implant device which connects to the implantable connector in order to provide access to the body conduit or vessel external from the body.          The connector includes a tubular member expanded along its length in order to form a bulbous portion; a side part is provided for connection to the implant device at the approximate midpoint of the tubular member bulbous portion.  The implant device has a passageway, which is either straight or curved at the outlet, an anchor means for establishing a biological anchor, and an optional grafting mesh annularly disposed about, and spaced apart from the exterior of the implant device.

Abstract: ACCELERATED DECAFFEINATION PROCESS                        L. R. Morrison J. H. Phillips ABSTRACT       This invention relates to an improved countercurrent extraction process for accelerated decaffeination of coffee beans, and to the novel decaffeinated coffee product generated thereby. In particular, turbulent flow of the extracting solvent is used to obtain a substantially accelerated decaffeination rate involving a caffeine extraction time of only from about 3 to about 5 hours. Since the rate of extraction of non-caffeine coffee solubles is not correspondingly accelerated, the decrease in extraction time mini-mizes the loss of these valuable materials. Use of multiple vessels in countercurrent operation also decreases the loss of non-caffeine coffee solubles, resulting in an improved decaffeinated coffee.

The first capacitor is thereby charged to the potential of a trigger reference over a resulting first time period.  A second bilateral switch is provided for flowing a charging current through the same resistive element to an initially-depleted second capacitor, thereby charging it to the potential of the same trigger reference over a resulting second time period.  A device such as an oscilloscope or frequency counter is used for determining these time periods and the value of the unknown second capacitor may thereupon be computer using disclosed formulas.    A method for determining the value of a capacitor includes the steps of flowing a charging current through a resistive element to an initially-depleted first capacitor of known value, thereby charging this capacitor to the potential of a trigger reference over a resulting first time period.  A charging current is then caused to flow through the same resistive element to an initially-depleted second capacitor for charging it to the potential of the trigger reference over a resulting second time period.  The value of the second capacitor is then computed by utilizing the first time period, the second time period and the value of the first capacitor.
