Abstract: A blow molded synthetic resin container has a body portion with a bottom wall and a sidewall of generally circular cross section, and a closure portion.  The sidewall has a pair of vertically elongated grip recesses defined by top and bottom walls and first and second walls extending therebetween and converging along an axial line at the maximum depth of the recess, with the inward angle of one hung steeper than the other.  The grip recess has a convex bridge rib extending horizontally and rectilinearly between the first and second walls and terminating at points spaced inwardly of the periphery of the sidewall to space its rectilinear outer surface inwardly of the periphery.  The first wall also has a plurality of ribs of smaller height and width than the bridge rib extending axially from both side surfaces of the bridge rib.

Abstract: A flying amusement device (10) including first and second rotary elements (12, 14) separated by a hub (16). Each of the rotary elements includes a set of lift members (18, 20) which provide lift in a common direction when the device is rotated about the hub. A length of flexible line (26) is connected to the hub (16) and wound thereabout prior to use. The device is held in the user's hand with the free end of the flexible line connected to the user's throwing hand. The device is then thrown outwardly from the body of the user with a snapping motion of the wrist to impart rotation to the device. This rotation produces lift, and further rotation is imparted to the device due to the device unwinding from the flexible sine as it travels away from the user. Upon fully unwinding the flexible line (26) from the hub (16), the continued rotation of the device (10) causes the flexible line (26) to be rewound upon the hub (16), thus drawing the device back towards the user.  During the travel of the device (10) away from and towards the user, the continued rotation of the device produces a lift which causes the device to fly through the air.

Title: Method and apparatus for reducing packing ring spin for trapezoidally shaped mechanically braided packing
Inventor: CHAMPLIN GEORGE B
IPC: D04C1/06
Filed: 1993-11-05
Granted: 2000-06-20
Abstract: A system for reducing packing ring spin and opening up of the joints formed by the ends of a packing ring during break-in of trapezoidally-shaped mechanical braided packing involves utilization of additional warp yarns within the sides of the packing. These additional warp yarns bulge the packing at the sides of the packing above its horizontal centerline such that the outer portion of the packing is provided with a solid rectangular cross section. The solid section increases frictional contact between the rings and the stuffing box and between the rings themselves to eliminate packing ring spin.      When the packing is wrapped around a shaft the bulging sides become flat for secure elongated anti-spin contact both between the packing rings and between the end ring and the bottom of the stuffing box. The utilization of the anti-spin configuration eliminates packing ring spin and the opening up of the joints formed by the ends of the packing rings during break-in, regardless of operator error in the installation of the packing rings.

Title: Low temperature caustic sulfide wet oxidation process
Inventor: MOMONT JOSEPH A
IPC: C02F1/74
Filed: 1994-03-16
Granted: 2005-01-25
Abstract: A process for treatment of caustic sulfide liquor by wet oxidation in a ferrous-based alloy system at temperatures less than about 175°C is described. The liquor is first analyzed for alkalinity consuming species and for nonsulfidic alkalinity. If excess alkalinity consuming species is present compared to nonsulfidic alkalinity, then additional nonsulfidic alkalinity is added to the raw liquor such that excess alkalinity is present during wet oxidation treatment, thus preventing excessive corrosion to the ferrous-base alloy system.

Abstract: The invention concerns a yarn bobbin with a rotationally symmetrical body the outside of which forms a surface which carries the yarn and which has a longitudinally protuding collar at one end. The aim of the invention is to design a bobbin of this kind which has the advantages of prior art bobbins but which, when wound, can be stacked with other, similar, bobbins without the yarn being damaged or snagged. The invention achieves this by virtue of the fact that the bobbin (1) has, at its end with the yarn uptake (2), an additional collar (3) which has the same external dimensions as the internal dimensions of the collar (4) at the other end of the bobbin but is staggered radially inwards with respect to the yarn uptake, the collar (4) being fitted with a yarn-reserve groove (6).

Filed: 1994-12-05
Granted: 1999-01-19
Abstract: Disclosed is a starter which is  simplified in the structure of its pinion rotation regulating mechanism and is down-sized in its entire structure.  A pinion regulating member (230)  abuts with a pinion (200)  and moves the pinion (200) towards a ring gear (100) by the rotation of an output shat (220), while preventing rotation of the pinion (200).  When the pinion  (200)  abuts with  the  ring  gear  (100),  the  pinion regulating member (230) bends and gradually rotates the pinion (200) to mesh with the ring gear (100).  By this arrangement and operation, generation of abrasion powder is reduced with reduced number of component parts.

Abstract: The shaft seal assembly of cartridge designed for sealing shafts entering or exiting enclosed vessels. The enclosed vessels may have a pressure different from the atmospheric pressure and the seal will normally prevent leakage from or into the vessel. The seal is accomplished by having a plurality of fluid pressures presented to different faces or portions of the seals. Utilization of these pressures provides a seal between the faces of the rotating parts and the stationary parts of the seal with a minimum of friction.      This reduced friction is a result of some amount of air movement between the sealing faces. This air movement into and out of the seal, resulting from fluid pressure different-ials, will also carry away any contaminants that may get into the seal, either to the ambient atmosphere or to a recovery system. The seal is designed to accept axial and radial shaft displacement while maintaining a positive seal between the vessel and the atmosphere. The seal of this invention inclu-des force loading of the rotating members toward the station-ary members, each member with its own sealing face. The force of the loading means is modified by utilization of a first pressure to decrease the loading force and a second fluid pressure proportionate to the first fluid pressure applied to increase the loading force. The first and second fluid press-ures provide a barrier to the flow of materials in either dir-ection through the seal. The rotating members are driven by drive rings which also act as sealing members along the shaft.
