Title: Golfer's two-arm swing linkage device
Inventor: CORDER WILLIAM O JR
IPC: A63B69/00
Filed: 1990-05-18
Abstract: Abstract of the Disclosure The  invention  relates  to  a  training  device  for improving a golfer's swing.  More particularly, the invention relates to a training device for limiting the movement of both arms relative to the golfer's body.  The device comprises a chest band and arm restraining bands that hold the golfer's arms close to the body and prevent their movement away from the body while at the same time permitting the movement of the arms across the body throughout the swing.

Abstract: PRESSURE COMPENSATING APPARATUS AND METHOD FOR CHEMICAL TREATMENT OF SUBTERRANEAN WELL BORES                   ABSTRACT OF THE DISCLOSURE    An apparatus for effecting chemical treatment of a subterranean well bore comprises vertically spaced, inflatable packing elements which are run into the well on a fluid conduit, such as continuous coiled tubing, or the like.  The apparatus permits circulation while being run into the well and, when positioned, effects the expansion of the two inflatable elements by pressured fluid introduced through the supporting fluid conduit.  The applied pressure is trapped within the inflatable elements by axial movement of an inner body relative to an outer body, which effects the opening of fluid communication between the central fluid conduit and the well bore portion between the inflated packing elements, permitting testing of the sealing effectiveness of the packing elements, and the ap-plication of a treatment fluid.  The same movement, accompanied by an increase in fluid pressure effects the opening of a fluid path to the well bore above the uppermost packing element.  The pressurizing fluid remaining in the fluid supply conduit may be discharged into the well annulus by supplying pressurized treatment fluid through the supply conduit.  For deflation of the inflatable packing elements, the central body is moved downwardly by the spring, a circulation port is opened and a rupture disc is ruptured through the application of preselected higher fluid pressures.  In order to compensate for a pressure variance as a result of the initiation of the release sequence involved in deflating the inflatable packing elements, a pres-sure compensating member is provided, with the member having a EXPRESS MAIL NO. B76921555 cylindrical outer housing and a valve housing concentrically movable relative to and within the cylindrical housing.  A fluid flow passageway is within the valve housing and extends to the top of the well.  Valve head and seat means are carried by the housing for selective blocking of fluid flow in one direction through the passageway when the valve head and seat means are in a first relative position and permit fluid flow in that direction through the valve housing when the valve head and seat means are in a second relative position.  A pressure chamber is provided within the outer housing and extends to the lowermost side of the valve head means.  Biasing means are provided for biasing the valve housing to contract the pressure chamber with the biasing means being energized by a decrease of pressure within the fluid supply conduit such that the valve housing is moved relative to the outer housing to expand the pressure chamber without movement of the valve head means relative to the valve seat means.  The compensating valve mem-ber may also be used independent of the inflatable apparatus either alone or in combination with another auxiliary tool within the subterranean well.

Title: Method for determining the optimum angle for displaying a line on raster output devices
Inventor: KAASILA SAMPO
IPC: G06T11/20
Filed: 1990-09-20
Abstract: ABSTRACT           The present invention is a method for determining the optimum angle for displaying a line on raster output devices.  The preferred embodiment defines the possible adjustments of a line as it is being displayed at a raster resolution as a penalty which comprises of a weighted sum of a distance variable and an angular variable.  The weight permits the user to decide between a trade-off between the fidelity to original angle and the quality of a line being displayed.  To determine the optimum angle for displaying a line at a particular raster resolution, the present invention finds the angle with the smallest penalty.  The optimum angle is further constrained by a plurality of variables set by the user.  Once the user provides the constraints on the minimum penalty, the present invention automatically determines the optimum angle for displaying a line on a raster output devices.     LYH/04860.P22 1

Abstract: A method of continuously digesting comminuted cellulosic fibrous material (e.g. wood chips) is provided which simultaneously improves uniformity of the end product and has substantial energy economy.      The chips are slurried, e.g. with black liquor, and fed to the top of a vertical digester. In the digester the chips are soaked in and heated with black liquor withdrawn from near the bottom of the cooking zone, which black liquor is at cooking temperature. White liquor (kraft cooking liquor) introduced into the cooking zone is preheated by passing it in heat exchange relationship with a portion of the black liquor withdrawn from the digester, so that only a small amount of heat in the form of steam need be added to the white liquor to bring it to cooking temperature. At the top of the digester, a portion of the liquid in the slurry can be withdrawn through a screen, pressurized, and then introduced under pressure with a downward velocity component facilitating a zone of concurrent movement of the chips and liquor.

Title: Bellow-type pump with a plurality of radially arranged bellows
Inventor: HOEHN NORBERT
IPC: F04B45/027
Filed: 1990-05-08
Abstract: (57) Abstract A bellow-type pump comprises a plurality of bellows (51) to (54) grouped radially about the drive axis and driven simul-taneously so that the torque is applied uniformly. Asymmetrical loading of the bellows, which reduces their service life, is prevent-ed by improved coupling of the eccentric movement of the drive shaft (34) with the bellows. The outlets (62) from the individual bellows can be connected in parallel or in series, as desired, so that a greater delivery volume or higher delivery pressure can be attained, depending on requirements. The pump housing (1) consists of a double-cross piece used as an assembly unit in ultra-high vacuum technology. To ensure complete evacuation of the pump, for example to allow subsequent introduction of ultrapure gases, spring-loaded valves (82) which block the direction of flow are maintained temporarily in an open position during normal operation. To this end, the closure bodies of the valves are made from a magnetic material and can be influenced by a magnet (84) mounted on the outside of the pump housing (1, 73), which is made from non-magnetic material. The valve returns to its closed position immediately the magnet (84) is brought into, and possibly stopped in, a remote position.
