Abstract: A clinch type staple has a U-shaped configuration with a pair of legs extending generally perpendicularly from a base portion of the staple with the outside surfaces of the distal ends of the legs being-bevelled. The legs of the staple lie in spaced apart planes that are parallel to one another, but are angularly offset from one another in order to insure that the legs will not contact or interfere with each other as they are clinched into a workpiece.  A plurality of such clinch staples can be manufactured into an assembly of clinch staples.  The method of  making such an assembly of clinch staples includes advancing a plurality of wires in parallel side-by-side relation in a flat planar array and adhering the wires to one another.  A blank, severed from an end of the formed array, includes a plurality of side-by-side wire segments of equal length extending parallel to one another in a first direction.  The severing of the wires is accomplished along a cutting line that is inclined by a bias angle from a perpendicular to the first direction.  The blank is bent along two bending lines to form a U-shaped stick of clinch staples with the legs extending perpendicularly from a base or bight portion of the staples.  The two bending lines are parallel to the cutting line so that the legs of the formed staples will be offset angularly from each other.

Title: Frequency Reuse Technique for a High Data Rate Satellite Communication System
Inventor: ROSEN HAROLD A
IPC: H04B7/204
Filed: 1994-10-12
Abstract: 14 FREQUENCY REUSE TECHNIQUE FOR A HIGH DATA RATE SATELLITE COMMUNICATION SYSTEM ABSTRACT Frequency reuse (70) and data coding methods (80, 90) for use in a high data rate satellite communication system (10). The frequency reuse method (70) provides for dual polarization and spatial reuse of transmit and receive beams to provide for a twelve-fold increase in the effective bandwidth and number of users that may be supported by the system (10). Transmit and receive antennas provides multiple, inter- leaved transmit and receive antenna beams. Digital input data at a source user terminal is coded and transmitted from a source user terminal on one of the plurality of receive antennas is demodulated. The received data is demodulated demodulated and is routed so that it may be transmitted to a destination user terminal. The data is then remodulat- ed, multiplexed, and transmitted to the destination user terminal on one of the plurality of transmit beams. The transmitted data is decoded at the destination user terminal to produce the output data. The input and output data processed by the system is digital, and the coding (concatenated coding forward error correction processing) is employed to reduce the sensitivity of communicated data to interference. The presently preferred encoding method comprises Reed-Solomon encoding (42) input data, interleaving (43) the encoded data, and convolutionally encoding (44) the interleaved data and then time division multiplexing (45) and modulating (46) the data. The presently preferreddecoding method comprises demodulating (56) and demu ltiplexing (57) received time division multiplexed data, Viterbi decoding (58) the demultiplexed data, deinterleaving (59) the Viterbi decoded data, and Reed-Solomon decoding (60) the deinterleaved data to produce the output data. Other multiplexing schemes may alternatively be employed. The demodulating and demodulating steps regenerates a high quality digital data stream on the satellite that is communicated to the destination terminal to reduce the effects of uplink interference upon the downlink data stream.

Patent CA-2121279-A1 (CA)
Inventor: NOFER KARL H
IPC: B65D50/04
Filed: 1994-04-14
Abstract: A closure has a central portion with a periphery and a skirt extending from the periphery, a tear strip extending from the skirt, a tamper evident band extending from the tear strip and a movable flange extending from the band.  The flange is hinged so that the tamper evident band has equally spaced windows in it to make it flexible so that it can be stretched over the ring with a very small tolerance or even a negative tolerance relative to the ring.  Once the flange has overridden the ring, a free edge of the flange moves inward to rest against an outer surface of the neck beneath the ring.  The closure can then not be removed from the container without first severing the tabs as the flange will not override the ring during removal of the closure.  The tabs are severed by manually grasping a handle of the tear strip and removing the tear strip. When the tear strip is removed, the closure functions in a conventional manner for opening and closing the container.  The screw thread on the closure is made up of elongated bubbles located end to end.  A core for a mold to make the closure containing the bubbled screw threads can be manufactured using a ring-shaped electrode having a cylindrically-shaped inner surface.  The electrode is connected to a high voltage source and mounted in an electrical discharge machine, there being a contact point on said inner surface for each bubble to be formed in said screw thread.     With previous devices, the closure contains conventional screw threads and dusting is a major problem or, the flange does not contain windows and cannot be manufactured on a large scale with appropriate tolerances.

Title: Method of opening fibers using a modified disperser plate
Inventor: FREUND KENNETH S
IPC: D04H1/72
Filed: 1992-11-18
Abstract: A method is disclosed for opening fibers. Preferably, the fibers are opened in the high speed production of uniform, lightweight webs by air-laydown of textile fibers. In a preferred embodiment, a rotating toothed disperser roll is used to open and doff fibers into an air stream of high uniform velocity and low turbulence to form a thin fiber stream from which the fibers are deposited inweb form on a moving screen. A curved disperser plate shrouds the disperser roll and prevents premature doffing. By using a specific disperser plate having an exposed rib length between 0.01 to 0.20 inches and a rib spacing between 0.15 to 2.0 inches, web quality is dramatically improved due to the significantly lower number of defects remaining in the web as unopened fiber chips.

Title: Method and apparatus for cardiovascular diagnosis
Inventor: ERDMAN FRANK H
IPC: A61B6/00
Filed: 1994-09-27
Abstract: A non-invasive method and apparatus for sensing relative blood conditions in extremities, such as using photoelectric dermachromography to measure differential blood flow and/or pooling between extremities, for the purpose of diagnosing cardiovascular conditions. Reflective colorimeters are employed for performing comparative light reflection rheology (LRR).  The resting, steady-state LRR for both the left and right palms are simultaneously measured when both arms are in a raised, steady-state condition, and again when both arms are in a lowered, steady-state condition, thereby providing a repeatable measurement of overall vasomotor tone, the tone of the smooth muscles of the arterial walls.  Two portable light gauges are used, each including a plurality of light sources such as light-emitting diodes (LEDs) arranged around at least one light detector. Each gauge is removably attachable to the palms of the hands of the patient whose vasomotor tone is to be determined.  The gauges are removably attached to the palms so that the hands are movable, and measurements are taken of both hands in a raised, substantially steady-state UP condition, and then again while both hands are in a lowered, substantially steady-state DOWN condition.  After a series of these UP and DOWN measurements are taken, the gauges are switched and another series of UP and DOWN measurements with the gauges reversed are taken.  Each gauge is independently calibrated by using standardized reference scales.

Inventor: HABERSTROH JAMES A
IPC: B65B13/22
Filed: 1994-11-29
Abstract: A novel method and apparatus for feeding and tensioning a strap in a power strapping machine. The apparatus includes a strap feeding mechanism, a strap tensioning mechanism, and a pivoting roller carriage pivoted by a feeding and tensioning cam. The pivoting roller carriage first actuates the strap feeding mechanism to engage a portion of a strap and feed the strap toward a strap application assembly where the strap is formed in a loop about an object or group of objects. The strap feeding and tensioning mechanism actuates a first gripper that secures an end of the strap in the strap application assembly. The pivoting roller carriage then actuates the strap tensioning mechanism to engage a portion of the strap and apply a tension to the looped strap. The strap feeding and tensioning apparatus also actuates a second gripper that secures the tensioned strap in a closed loop about the package so that the strap application assembly may form a strap joint sealing the strap in the closed loop. In the event that the strap is not properly engaged by the first gripper, the strap will be fully retracted from the strap application assembly by the strap tensioning mechanism and the strap will be directed into a strap stretch-out housing where it will remain until the strap feeding mechanism again engages a portion of the strap and re-feeds the strap toward the strap application assembly. The weight and position of the strap disposed in the strap stretch-out housing prevents the strap from withdrawing entirely from the strap feeding mechanism thereby ensuring that the strap feeding mechanism will engage and re-feed the strap to the strap application assembly automatically.
