Title: Method for controlling coating weight on a hot-dipping steel strip
Inventor: SATO TOSHIO
IPC: C21D9/56
Filed: 1992-06-24
Granted: 1996-12-17
Abstract: A method for controlling coating weight on a hot-dipping steel strip comprises the steps of positioning at least one pair of high-frequency current conducting paths near one side of a steel strip and near another side of the steel strip drawn out of a coating bath, each of the high-frequency current conducting paths being parallel with a surface of the steel strip above the coating bath, and flowing a high-frequency current strong enough to magnetically saturate the steel strip through the at least one pair of high-frequency current conducting paths to induce a high-frequency current of an opposite phase in the steel strip, a magnetic pressure acting on surfaces of the steel strip being generated by interaction of the induced high-frequency current with a high-frequency current of the high-frequency current conducting paths.

Title: System and method for selectively preventing a software program from being operable
Inventor: BENSON LAWRENCE DAVID
IPC: G06F9/445
Filed: 1992-07-17
Granted: 2000-09-26
Abstract: A system for selectively preventing a primary computer software program from being operable until a separate, secondary computer software program posing questions to the potential user of the primary computer software program has received answers to the questions using the keyboard of the computer. The system visually displays the questions from the secondary computer software program, determines whether the answers to the questions have been entered through the computer keyboard, verifies the format of the answers, records the answers for transmission to the software producer and then transfers the primary computer software program from a non-executable code form on one or more floppy disks to an executable code form on the hard dish drive of the computer.      The user responses are recorded in some convenient form for transmittal to the company. The form of transmittal may be printed, though recording on magnetic media or transmission by other electronic means is preferable.

Granted: 2002-01-15
Abstract: A space-dividing upright wall system wherein wall panels are supported on and connected through upright panel connecting members, the latter having a foot for engagement with a floor. The panel connecting member is preferably of Z-shaped cross section including parallel side legs joined by a diagonally-extending cross wall.      Each side leg has an upright row of slots which accommodate hangers associated with components which mount on the wall system. The slots in the two sidewalls are isolated from one another by the cross wall. Each side leg has vertically-extending rows of hooks projecting outwardly from opposite side edges thereof, which hooks cooperate with a pair of generally aligned panels for rigidly joining the panels together.      When two adjacent panel assemblies are disposed in generally perpendicular relationship to one another, then the adjacent end edges are each provided with a connecting member secured thereto, and the adjacent pair of connecting members in turn are directly joined together through an intermediate corner connector which engages a row of hooks on the connecting member which is not engaged with the panel assembly.

Title: Half-step stability cane
Inventor: WALLUM RONALD I
IPC: A61H3/00
Filed: 1993-06-11
Granted: 1996-06-18
Abstract: A  combined  stability  cane  and  device  for assisting a handicapped person in traveling up and down a flight  of  stairs  having  vertically  spaced  steps  is disclosed.   A rectangular block member or platform has a flat upper surface within which a connector mechanism is provided  at  its  central  area,  and  a  second  connector mechanism is provided in the upper surface adjacent one of the sides of the block member and opposite the central area. A  walking  cane  having  a  cooperative  connector mechanism  adjacent   its lower   end   is   provided  to alternatively rigidly connect the same to one of the two connector mechanisms  in the upper surface of  the block member.   When  the  cane  is  connected  to  the  connector mechanism  at  the  central  area  of  block  member,  the combination  functions  as  an  excellent  stability cane. When  the  cane  is  connected  to  the connector mechanism adjacent  one  side  of  the  block  member,  the  latter functions as a half-step which the handicapped person may utilize to  facilitate  travel up and down the steps by taking only a half-step at a time, at first on the block member and then upon the next step, thereby reducing the elevation change required through a series of half-steps. Alternatively, the walking cane may be disconnected from the block member  so  as  to use the same  in  its  normal manner.

Filed: 1993-01-21
Granted: 1998-11-24
Abstract: The present disclosure includes a discussion of a method of synchronizing a sampling clock signal to a received data signal (131). The clock recovery circuit (127) generates several clock signals (339 341, 343, 345) at the symbol rate, with each clock signal having a unique phase. To permit fast initial acquisition, the set of clock signals includes a pair of clocks which differ in phase by one-half of a symbol interval. Additionally, the clock recovery circuitry (127) generates error signals (347 349, 351 353) representing the difference between the phase of the received data signal and the phase of each clock signal. The error signals (347, 349, 351, 353) are processed over multiple symbol times to determine the optimal sampling phase. The clock recovery circuit (127) then adjusts or maintains the phase of the symbol clock (139) to provide the optimal sampling phase.

Abstract: Hollow  synthetic  monofilament  yarns  are  used  in  the construction of a base fabric for a papermakers wet felt.   The synthetic hollow monofilament yarns have selected interior void, compressibility and resiliency characteristics and are interwoven with other yarns to form a woven base fabric with the hollow monofilament yarns predominating, on at least the paper carrying side of the base fabric.  The weaving and finishing of the base fabric  results  in  the  hollow monofilament  yarns  retaining  a substantially    unflattened    cross-section.        Accordingly, substantially unflattened portions of the hollow monofilament yarns predominate the paper carrying side of the base fabric thereby providing a cushioning surface which is compressibly resilient to assist in the dewatering of the  aqueous paper web as  it  is transported through a press nip during the manufacture of the paper.  Hollow nylon monofilament yarns having approximately 18% internal  core  void  have  been  found  to  exhibit  the  desired compressibility  and resiliency characteristics.    Preferably a fibrous batt is needled to the base fabric to finish the wet press felt.

Granted: 2004-02-10
Abstract: Numerous products can be formed by combining a low melting matrix made up of one or more metals and high melting, high density metal particles and wherein the products can be formed by adding the high density particles to a molten matrix metal and casting same; mixing powders of all the metals together, compacting and sintering at a temperature in the low end of the melting range of the matrix alloy, or by mixing the high density particles into a paste of the matrix alloy and molding. These methods and compositions are particularly adaptable for use in forming low or non-toxic high density projectiles, such as, shot, bullets and pellets having a density comparable to that of lead while avoiding problems of toxicity associated with the use of lead.
