Abstract: ABSTRACT OF THE DISCLOSURE        A low grade roasted coffee fraction is extracted with water in a manner sufficient to remove at least 75% of the caffeine contained therein while retaining a major amount of the soluble solids. Volatiles are stripped from the resulting extract and condensed. Thereafter the low-grade fraction is thoroughly extracted with an aqueous extraction medium and this extract is combined, either before or after drying, with a fully caffeinated water extract of a high-grade coffee fraction and with condensed volatiles from the stripping operation. A partially decaf-feinated soluble coffee having desirable flavor and aroma may be obtained.

Abstract: MULTIPLE ARM PAD INSTRUMENT FOR LOGGING HIGHLY DEVIATED BOREHOLES           Abstract of the Disclosure.  A borehole instrument having four arm pad members utilizes four independent bow springs, each of the bow springs being anchored to the instrument at one of their ends and being individually slidably mounted at their other ends to the instrument.  A push-pull rod activated by a solenoid within the instrument causes each of the slidable collars connected to the bow springs, respectively, to move down and thus close the instrument for easy passage through the borehole when not logging.  When the push-pull rod is pulled up, each of the bow springs acts independently to cause the individual pads to make contact with the borehole wall.  In an alternative embodi-ment, spring-driven pad linkage assemblies are likewise closed by pushing on the push-pull rod and are allowed to open and move out against the borehole wall when the rod is pulled up by action of the solenoid.     -1a--

Abstract: Abstract of the Disclosure A pair of seat ring members are loosely mounted in annular recesses around the longitudinal bore in a gale valve body at the intersection of the bore and the valve chamber on opposite sides of the gate member.  Each of the seat ring members has a rear face comprised of a pair of stepped portions connected by an outwardly facing annular surface portion.  Each seat ring has a groove at the juncture of the outer stepped surface portion and the outwardly facing annular surface.  A seal ring chamber is formed between the recess annular wall, the stepped outer surface portion, the outwardly facing annular surface and the grooves.  A resilient O-ring is positioned in the seal ring chamber.  The O-ring has a sufficient cross section to seal between the recessed end wall and the outwardly facing annular surface when initially positioned in the seal ring chamber upon assembly of the valve.  When an unbalanced pressure condition is present across the downstream O-ring then that O-ring is dis-placed radially inward and partially enclosed in the groove in order to prevent ex-cessive compression thereof, while at the same time the upstream O-ring maintains a seal between the upstream recess end wall and the upstream outwardly facing annular surface.

Abstract: ABSTRACT         A digital data recovery apparatus for extracting phase encoded data from mass storage devices is disclosed.  Storage device clocking signals are counted and compared to expected number of counts determined by a reference clock.  The difference between the expected count and the observed count is used to vary a window clock which determines the length of time groups of data signals can be exchanged with the storage device.  The recovery apparatus uses digital components and eliminates the need for phase-locked oscillators implementing analog devices.

Abstract: ABSTRACT OF THE DISCLOSURE     The instant invention relates to a method of preparing an electrical contact from sub-micron size silver particles and less than two micron size cadmium oxide particles with the contact having finally dispersed particles of cadmium oxide within grains of silver.  In the instant invention particles of silver and cadmium oxide are intimately blended together and subjected to a reducing atmosphere at a tem-perature of from 321°C to 550°C to reduce the cadmium oxide and form an alloy powder of cadmium and silver.  The mixture is held at an elevated temperature following reducing and then oxidized at a temperature of from 321°C to 550°C to precipitate a dispersion of cadmium oxide within the grains of silver.  Lithium in a suitable form is then added to the resultant silver cadmium allow powder.  In an alternative embodiment an alloy powder of cadmium and silver already prepared from sub-micron size particles of silver and less than 2 micron size particles of cadmium oxide is heated to a temperature of from 321°C to 550°C in an inert atmosphere.          The inert atmosphere is then changed to an oxidizing atmos-phere at that temperature to precipitate the dispersion of cadmium oxide within the grains of silver and then lithium is added in a suitable form.  The material as prepared by both embodiments is then formed into an electrical contact.          The instant also relates to the electrical contact produced by the methods of the invention.

Abstract: Abstract of the Disclosure A vibration accommodating clamp for securing pipes which carry brake lines and the like to the underframe of railway cars.  The clamp is initially mounted by placing a U-shaped bolt over the pipe and the legs, which are spaced from and offset with respect to the outside diameter of the pipe extend through holes in a mounting bracket.  A collar is permanently secured on a grooved portion of one leg of the bolt. The second leg of the bolt which extends through a hole remains unused until it is necessary to remove the clamp.  The clamp is removed by cutting off the collar and reapplied by placing a nut and washer on the threaded portion of the previously unused leg. In either case, the hole through which the unsecured leg extends has an inner peripheral surface radially spaced a predetermined distance from the unsecured leg thereby accommodating limited stress attenuating deflection of the unsecured leg.  The unsecured leg is reactively engageable against the inner peripheral surface to abate excessive movement of the unsecured leg attendant to predetermined dynamic loading on the pipe during high speed rail operations thereby preventing substantial deflection of the unsecured leg from a generally perpendicular disposition relative to the plane of the bracket hole.

The valve comprises an elongated housing with an interior cylindrical passage and a cylindrical valve seal member.  A valve lever member including with a valve head member and a lever arm is formed with a spring retainer cavity and a spring is inserted in the housing to center the valve lever member.  Deflection of the valve arm causes the valve head member to pivot and partially lift off the valve seat.  The lever arm is returned to the center position by the spring when the animal lets go of the lever thereby automatically preventing further water flow.  The present device provides an improved automatic device over the prior art by reducing the clogging problem while maintaining adequate water pressure.
