Abstract: ABSTRACT          RADAR SIGNAL SIMULATOR      There is a need for apparatus which simulates signals received by a Radar antenna.   Such apparatus is needed for testing Radar equipment and for training purposes.   Hitherto such signals have not looked very "real" when displayed on the Radar screen.    The invention is believed to meet this problem.      The invention provides two stores which hold respectively the horizontal and vertical polar diagram characteristics of an antenna   The appropriate values are read out of these stores by signals representing the azimuth and elevation angles of an immaginary target and the antenna (which may be real or imaginary). The outputs from the stores are combined to give a realistic simulated signal.      The polar diagram characteristics of an antenna may be different for transmission and reception.   To take this into account each store may be provided in duplicate andthe outputs from all four stores combined to produce the simulated signal.            .

Abstract: ADJUSTABLE VEE BLOCK CLAMP                          ABSTRACT This invention relates to a work holder for holding a workpiece,  Clamps having flat jaws and screw thread advances cannot engage the curved item over a large surface,  Thus, the force that the jaws exert to hold the item is concentrated over a small area,  This concentration can cause deformation or destruction of the item to be held.  Further, the limited area of contact may be insufficient to give the clamp an effective hold on the item.  Prior art vee block devices are complex in construction, and the operator must insert or remove shims under the device to change the vertical location of the device and the item held.  Inserting and removing shims is time-consuming and increases the cost of setting up a machine operation.        The present invention overcomes the deficiencies of the prior art by providing an improved vee block clamp intended chiefly to hold items having a curved outer surface.  A central block has an inclined edge facing the front of the clamp and two side blocks adjacent the cen-tral block have inclined edges facing the rear of the clamp.  Central block channels mateably engage the side blocks to provide alignment,  The blocks are held together by a threaded fastener and slidable positioning of the blocks is achieved by a slot in the central block through which the fastener  passes.  An adjustable top arm holds the items engaged against the inclined faces.

Abstract: Abstract A purpose of the disclosed method is to impart gathers and elasticity to a relatively inelastic film, membrane, or web substrate, through elastic banding with a viscoelastic hot melt pressure-sensitive adhesive (PSA).  Typically, the resulting elastic-banded substrate product (e.g. 40) will be cut into discrete units and formed into garments or body-encircling members such as disposable diapers.  One step of the preferred method involves extruding a ribbon or band (13 or 113) comprising a viscoelastic hot melt PSA, which PSA has unusually high cohesion, stretchiness, and elasticity without excessive loss of adhesive bonding strength.  (The viscoelastic behavior of the PSA is believed to be determined, at least in part, by the rela-tive size of its crystalline domains and its rubbery domains and the glass transition temperatures and soften-ing points of its components.)  A second step of the preferred method involves bringing the band of hot melt (13 or 113) into adherent contact with a surface of a moving continuous substrate (22 or 32 or 132).  A typical substrate would be the polyolefin film used is the manufacture of disposable diapers. The band can be bonded to the substrate through a pressure activation technique, wherein the band itself has the necessary inherent adhesive properties.

Abstract: ABSTRACT OF THE DISCLOSURE     A device for pumping a liquid or gaseous current medium has a casing designed to guide the flow of the current medium and a rotary bearing motor driven rotor wheel designed to pump the current medium through the casing.  The rotor wheel is equipped with a number of blades mounted on a shaft or other machine part whose function resembles that of a shaft, the blades being installed one behind the other in series in the direction of circulation.  The blades project almost radially outwards in one embodiment and extend over the axial length of the rotor wheel in another embodiment.  A partition fitted to the rotor wheel separates the volume flow of the medium pumped through the casing into an incoming pumping medium current, e.g. the inlet air or external air current, and an outgoing pumping medium current, e.g. the expelled air or out-going air current.  At least one heat pipe is fitted permanently to each blade, and rotates with its respective blade.  One axial end of the heat pipe is directed toward the incoming pumping medium current, e.g. the inlet air or external air current, and the other axial end of the heat pipe is directed toward the outgoing pumping medium current, e.g. the expelled air or outgoing air current.

Abstract: Abstract An infusion package, such as a tea bag, has a stable three-dimensional expanded configuration and a flattened configuration suitable for packing.   Preferably, the bag has a generally tetrahedral shape whereby its internal volume is greater that that of prior bags of essentially similar height and width and whereby the tea leaf particles are less constrained during brewing. Although ordinarily such a shape would be inconvenient for packing purposes, folds in the tea bag permit its collapse to a flattened configuration that can be packed in quantity.   A string or plastic strip can be affixed at or near a fold so that, by pulling on the string or strip, the bag can be expanded to its stable, three-dimensional configuration.

Abstract: 13                  48,571 ABSTRACT OF THE DISCLOSURE A multiple tube pulling apparatus for pulling, at one time, a plurality of stub-tubes from the tubesheet of a steam generator.  Each tube gripping apparatus of the plurality  is  expanded  into  gripping  arrangement by  an axially retracted tapered rod.  As the internal diameter of each stub-tube can vary, the amount of axial movement of each tapered rod to provide proper gripping engagement also  varies.   The  present  invention provides  a  single hydraulic  cylinder  for  axially moving the plurality of tapered rods and includes spring members connecting each tapered rod to the hydraulic cylinder to accommodate the variations  in  axial movement  of  each  rod necessary to obtain the proper gripping engagement for each stub tube. Further, a spring biased guide block maintains the grip-ping tubes on proper centers corresponding to the stub-tube centers and once the stub-tubes are removed from the tubesheet, the guide block pushes the stub-tubes off the tube gripping apparatus freeing the apparatus for another operation.

Abstract: "DISC-TYPE CHECK VALVE"                          ABSTRACT OF THE DISCLOSURE The valve comprises a bored housing formed of two segments. A discrete annular seat member is positioned on an annular shoulder formed in one segment.  A guide member, comprising spaced apart legs and an apertured end wall is positioned on the seat member.  A cylindrical, resilient plastic disc is positioned to seat against the seat member to close off flow through the bore and to slide within the guide member when unseated.  Flow bypasses the unseated disc by moving through the spaces between the guide member legs and out through the end wall aperture.            The plastic disc provides a particularly good seal and thus erosion of the seat is diminished.  Having the seat member removable reduces reconditioning costs.
