Abstract: ABSTRACT OF THE DISCLOSURE           An improved method of brewing coffee and a device therefor are disclosed.  The method involves the steps of providing a coffee brewing device having a porous housing containing a supply of ground coffee and having a self-supporting handle dimensioned to be hand-held attached thereto for positioning and stirring the housing in a liquid, the housing also including a vent for venting gases from an interior portion of the housing, the gases being generated during brewing, at least partially submerging the housing in the liquid and stirring the housing in the liquid sin the handle to produce a flow of liquid in the housing, and controlling the flow of liquid produced within the housing to create turbulence therein to agitate the ground coffee while the generated gases are being vented from the housing by the vent for rapid brewing of the coffee.  The turbulence is created by changing the direction of the flow within the housing using baffles positioned inside or on a side of the housing and/or by providing a flexible porous side wall of the housing which can flutter during stirring, that is, can move a substantial distance inwardly and outwardly with respect to the adjacent housing during stirring to create turbulence in the liquid flow within the housing to agitate the ground coffee. Another manner of creating turbulence includes the provision of irregular surfaces on the housing sidewall and/or baffle to disrupt laminar flow thereby creating a turbulent state.

Abstract: ABSTRACT A method of evaluating geologic rock samples and particularly sandstone.  The sample is saturated with fresh water and the temperature of the sample is reduced to a temperature below the freezing point of the fresh water.  As the sample is warmed, nuclear magnetic reso-nance measurements are made at just below 0°C and again at about the operating temperature of the NMR probe, i.e., about 32°C.  The portion of the water within the sample that can be considered to be residual water can be deter-mined from the relationship of NMR measurements taken at just below 0°C and at the temperature of the probe.

Abstract: ABSTRACT OF THE DISCLOSURE    A method and apparatus are provided herein for seating a gasket in one end of a plastic pipe by using a shaped mandrel.          The method includes the steps of heating that one end and softening the plastic sufficiently to make it pliable.  Then a hard configured ring is positioned on a medial portion of the mandrel, thereby defining an outer ring periphery of a diameter that is larger than the diameter of the mandrel, and also defin-ing an annular, radially-inwardly-exposed, angular junction in the ring.  Then the heated end of the pipe is applied over the mandrel and over the outer periphery of the ring to form a shaped bell with an annular, radially-outwardly-extending pocket therein.   The heated pipe end is then urged into overall contact with portions of the mandrel and with the outer periphery of the ring.  The heated pipe end is then cooled, resulting in encapsul-ating the ring within the annular pocket of the shaped bell.  The mandrel is then disassociated from the shaped bell and from the hard ring.  Finally, a resilient gasket is applied interiorly of the bell in contact with both portions of the annular pocket and the annular angular junction of the ring.  The apparatus includes: (a) belling mandrel means having a medial portion and an outer diameter sufficient to impress a bell shape in one pre-heated end of the plastic pipe; (b) a hard configured ring insertable on the medial portion of the mandrel, the ring having an outer peripheral ramp to provide a shaped profile of a diameter that is larger than the outer diameter of the belling Abstract of the Disclosure continued (page 2) mandrel means, and also defining an annular, radially-inwardly exposed angular junction in the ring to define configured, annular surfaces to secure a gasket therein; (c) means in the belling mandrel means releasably to retain the hard configured ring in association with the belling mandrel means; (d) means for urging the preheated pipe end into overall contact with portions of the mandrel and with the outer periphery of the ring; (e) means for cooling the preheated pipe end and thereby encapsulating the ring within the annular pocket of the shaped bell; and (f) means for disassociating the mandrel from the shaped bell and from the hard ring.

Abstract: Abstract of the Disclosure Load Sensing Circuit of Load Responsive Direction Control Valve A load sensing circuit of a load responsive direction control valve including a device for sensing load pressure signals, identifying those load pressure signals as positive or negative and transmitting those identified positive or negative load pressure signals to the throttling compensator controls of the load responsive valve, while also transmitting the positive load pressure signal to the pump control.  The identification and distribution of the load pressure signals to the controls of the load responsive circuit can take place with the direction control spool in its neutral position.  Therefore such a load pressure sensing and transmitting circuit is capable of anticipating the command signal indicated control function.

Abstract: Abstract of the Disclosure Control Circuit for Positioning An Earthmoving Blade Fluid control circuits are commonly used to control actuation of a pair of cylinders for positioning an earthmoving blade.  The known circuits for providing the three operating modes of the cylinders utilize a separate control valve for each cylinder thereby making precise positioning of the blade difficult since such positioning requires coordinated control of both valves.  The subject fluid control circuit includes a selector valve for determining the direction of fluid flow to and from the head end and rod ends of the tilt cylinders and a single control valve for modulatably controlling the fluid flow from the pump to the cylinders.  With this circuit, the selector valve can be prepositioned in the desired position prior to actuating the control valve so that positioning of the blade is readily controlled by manipulation of only the single control valve.

Abstract: OIL PAN SNAP ON STUDS   ABSTRACT OF THE DISCLOSURE         The installation of an oil pan on an engine block is facilitated through the use of studs consisting of a shank that is threaded at one end and tapered at the other, and has a resilient wire projecting from the side of the stud and towards the threaded end.  Before the oil pan is installed,  four of the studs are screwed into spaced bolt holes in the engine block.   The oil pan is then  lifted  up  onto  the  studs  and pressed over  the springs.   The springs compress and then expand on the underside of the oil pan flange to hold the pan in place while bolts are installed in the remaining bolt holes.          The  studs  can  then  be  removed  and  the  final  bolts installed.   This obviates the use of a second person to hold the pan in place while it is being installed and maintains alignment of the pan so that the pan gasket is not displaced during installation.

In the example shown the release elements comprise two cylinders 34, 35, each in its corresponding cylinder 36, 37 formed in the housing 11, the pistons 34, 35, when compressed air is supplied to their respective piston chambers 42, 43, pressing against the operating elements 27, 28 of the snap-lock mechanism 22 and releasing the tool from the coupling 16.
