Title: Strain gage assembly for measuring excessive tensile strain of a flexible elongated member, such as a steel structural cable, or an electrical transmission cable, or a glass fiberoptic communication cable, which may slightly twist under tensile strain
Inventor: TIJMANN WILLEM B
IPC: G01L1/10
Filed: 1991-04-10
Granted: 2002-06-25
Abstract: A strain gage assembly is secured between two initially longitudinal locations on the exterior of a flexible elongated member, such as a steel structural cable, or an electrical transmission cable, or a glass fiber optic communication cable, after or before the installation of the flexible elongated member, to thereafter upon the subsequent pre-stressing and/or the possible excessive straining of the cable, create an observable or transmittable reading of the excess tensile strain being sustained by the flexible elongated member. This strain gage assembly includes, in one embodiment, the in line arrangement of a vibrating wire strain gage, having the vibrating wire thereof secured to a calibrated coiled spring, which in turn is secured to an inner tube shaft, which in turn is telescopingly fitted within an outer tube shaft, that is secured to the vibrating wire strain gage. By using two spaced securement means, such as clamps, this strain gage assembly is secured to the exterior of a flexible elongated member. One securement means secures the combined vibrating wire strain gage and the outer tube shaft to the flexible elongated member at one location. The other securement means secures the combined calibrated coiled spring and the inner tube shaft to the flexible elongated member at a spaced second location. The inner tube slightly radially turns relative to the outer tube, within controlled limits, to compensate, if necessary, for any slight twisting of the flexible elongated member, which may occur when the flexible elongated member is excessively strained in tension.      This strain gage assembly, when installed, may also include a thermistor to signal temperature changes, a data transmission means via electrical cable leads of electrical circuits, and/or a signal transmitter means via radio waves, optionally utilizing satellite transmissions or meteor burst transmissions, and/or a protective cover, and/or a vibrating wire readout instrument.      When the flexible elongated member is a tieback steel structural cable, for example, the strain gage assembly created reading may be read at random times, at scheduled times, or constantly, during either static or dynamic loading periods of time.      Observations may be made before, during, and after earthquakes.

Title: Multiple access protocol
Inventor: LO WING FAI
IPC: H04L12/56
Filed: 1991-05-31
Granted: 1999-08-10
Abstract: The mobile station to base station access in a cellular radio system is a classical problem of random multiple access using a shared common channel. Many multiple access protocols have been invented in the past with varied degrees of success in improving the throughput of the multiple access channel. The current invention is a new multiple access protocol which enhances the throughput and reduces the access delay by providing feedback of the detailed status of the access channel from the base station to the mobile station. The feedback mechanism and multiple access protocol are also applicable to other types of radio or wire-based channels.

Title: Stretch-tape wrapper with positive-braking action
Inventor: FERBER NORMAN I
IPC: B65H75/18
Filed: 1991-07-31
Granted: 1998-05-12
Abstract: The wrapper of the invention includes a roll of stretch-tape on a central core, in its basic form, with a single end extension.          A cap is secured at the remote end of the extension, and an incompressible sheath encircles the extension to freely rotate when the wrapper is used with tape being drawn from off the roll.  The cap is dimensioned to prevent the sheath from separating from the extension, and is grasped by the heel of the hand of the user to prevent rotation of the extension when the tape is stretched, to be broken from the roll.  Because the cap is of greater dimension than the sheath, the wrapper can be hand-held and operated at any angle as the circumstances of use dictate.    In a second version, a pair of end extensions can be employed, making the use two-handed instead of one-handed, with the same type of braking action being provided by the caps being grasped by the heels of the hands of the user at either end preventing rotation of the stretch-tape roll.

Title: Paper machine for the manufacture of high bulk soft crepe paper
Inventor: ERIKSON JAN ANDERS
IPC: D21F9/00
Filed: 1991-04-18
Granted: 2000-06-06
Abstract: A paper machine for the manufacture of a soft crepe paper grade, which in respect of bulk and softness is fully comparable to the one manufactured in a paper machine made for through-air drying by hot air, is in principle a conventional soft crepe paper machine, in which a conveying and imprinting fabric (25) is substituted foe the pick-up felt. A pick-up device (23) operating with air flow picks up the web (15) from the forming fabric (9) and transfers it to the imprinting fabric (25) without any appreciable compaction of the web (15). The imprinting fabric (25) is maintained clean and dry by cleaning devices (41, 43, 45) and a device (47) for depleting the imprinting fabric (25) of water before it arrives at the pick-up device (23). Further, sir current generating devices (35, 37, 39) are provided Cor removing water from the paper web (15) by passing air of ambient temperature through the web (15). These have a capacity that is sufficient for raising the dry solids content of the web to at least 25 % before the web arrives at the Yankee dryer (29). If desired, the paper machine may easily and in a short time be converted into a conventional soft crepe paper machine, essentially by substituting a pink-up felt for the imprinting fabric (25).

Title: Master plate of optical memory device and manufacturing method thereof
Inventor: HIROKANE JUNJI
IPC: G11B7/24076
Filed: 1993-01-12
Granted: 1999-02-16
Abstract: A master plate of an optical memory device has a substrate having on a surface thereof a plurality of guiding grooves with a predetermined interval.   The respective edge portions of the guiding grooves are inclined with respect to the surface of the substrate at an angle not more than 30°. According to a manufacturing method for the master plate, the post-baking process is carried out at a baking temperature of not less than 150°C, and an etching gas containing °2 gas of 4 (SCCM) to 10 (SCCM) is used.  Thus, even when the copying is carried out with respect to the substrate of the optical memory device according to the injection molding process, wherein the stamper used is manufactured based on the above-mentioned master plate,  the mold release of the stamper can be carried out without being caught by the substrate.  Thus, it is possible to keep the respective shapes of the guiding grooves of the stamper, thereby enabling the substrate of the optical memory device to be manufactured with high repeatability.
