Granted: 1995-12-26
Abstract: Attache cases and business cases in general typically have a portfolio section for organizing papers and a main packing section.          Depending on  the  needs  of  the  user,  these  portions  can  be selectively closed off.  However, it's best that these sections are relatively accessible depending on whether the case is opened from the vertical position or whether the case is opened from the horizontal  position.    Accordingly,  Applicant  has  provided  a portfolio catch system which, depending on the orientation of the case, holds the portfolio in a closed position where the front of the portfolio is attached to the lid portion of the case, or in the alternative, if the case is opened from the vertical position, the panel is held to the base of the case, thus preventing the contents of the base from spilling and automatically permitting ready access to the contents of the portfolio.  Also disclosed is a series of lid containers and base containers arrayed along the upper edge of the lid and base shells at the upper side of the case.   These containers are readily accessible in all conditions of the case, and are especially accessible when the case is opened from the vertical position wherein access to the contents of the portfolio, as well as these lid and base containers, can be readily had.

Title: Overlapped multilevel codes
Inventor: WEI LEE-FANG
IPC: H03M13/00
Filed: 1993-02-24
Granted: 1998-08-25
Abstract: A multilevel coded modulation scheme trellis encodes a portion of the input data and the resulting encoded stream is used to identify a particular one of a predetermined number of subsets of symbols of a predetermined signal constellation. The remaining input data is coded using a Reed-Solomon (RS) code whose output is used to select for transmission a particular symbol from the identified subset. In applications in which phase hits or other channel phenomena may cause the received signal points to be phase-rotated versions of the signal points that were transmitted, differential encoding is included in the overall coded modulation scheme. In different embodiments, the differential encoding/decoding and RS encoding/decoding are in different orders. In one such embodiment, overlapped multilevel codes are used to preserve the advantages afforded by taking a multilevel coding approach.

Title: Method and apparatus for adjusting vehicle horns
Inventor: WILSON CARL R
IPC: B06B1/02
Filed: 1992-08-26
Granted: 1997-01-07
Abstract: Adjustment of the pulse energizing frequency and duty cycle of a vehicle horn is described.   The horn is blown by a test energizing circuit with a varying pulse frequency and the frequency at which the horn produces the maximum sound pressure level is taken as the predetermined resonant frequency.  Then the horn is blown by the test energizing circuit at the resonant frequency with a varying duty cycle and the value of duty cycle which produces a predetermined striking force of the plunger against the pole piece is taken as the predetermined impact-producing duty cycle which is used for setting the operating duty cycle of the horn in a manner depending upon the type of the horn.  The horn is then blown by its own electronic energizing circuit and the actual pulse frequency thereof is adjusted, preferably by laser trimming of a resistor, to match the resonant frequency.  Then the horn is blown by its own energizing circuit at the resonant frequency and the duty cycle is adjusted, preferably by laser trimming, to set the actual duty cycle in a known relation to the predetermined impact-producing duty cycle.

Title: Oilfield valve
Inventor: MCKNIGHT DEVEREUX J
IPC: E21B/
Filed: 1993-09-14
Granted: 2003-09-02
Abstract: A valve comprises a valve body having threaded connections on each end. A unit handled valve mechanism includes a cage carrying a spring loaded floating valve ball. The valve mechanism is placed in and removed from the valve body without the use of special tools. The valve mechanism includes lip type polyseals allowing pressure from below to leak past a lower valve seat so pressure from below causes the valve ball to seal only against an upper seat assembly. The only segment of the valve ball in substantial compression is immediately adjacent the upper seat assembly. An actuator for the valve fits onto a connector between the actuator and ball in only one manner, so the indicator on the actuator correctly points at the correct indicia on the valve body describ-ing the valve condition, i.e. open or closed. An improved connector between the actuator and the valve ball minimizes the potential of deformation due to abuse.

Abstract: The present invention is concerned with novel silanes and their application for the silanization of dielectric materials for anchoring biologically active compounds. The silanes have the general formula I (R1R2R3)Si-Y-X wherein R1, R2 and R3 signify alkyl, alkoxy or halogen, but at least one of these groups is alkoxy or halogen, Y signifies an alkylene chain [-CH2-(CH2)n-CH2-], a fluoroalkylene chain [-CH2-(CF2)n-CH2-], (-CH2-(CF2)n-CF2-] with n = 1-20 or an oligooxyalkylene chain -[(CH2)n'-O-(CH2)n"]m- with n', n" = 2-6 and m = 2-6 and X signifies an epoxide, an anhydride of a dicarboxylic acid with 4-5 C atoms, an isothiocyanate, an aryl carboxylic acid chloride or an aryl sulphonic acid chloride, provided that at least one of R1, R2 and R3 is halogen when X signifies an epoxide.      The new silanes according to the invention offer the following advantages:      The reactive groups X of the silanes are hydrolysis-stable but sufficiently reactive for the immobilization of an organic or biological recognition molecule to take place without further activation of the silane layer.      The silanes are suitable for the direct coating of dielectric materials, in particular of dielectric waveguides which are preferably made of ZrO2, HfO2, Ta2O5, SiO2, Al2O3 or TiO2.      The silanes can be applied to the surface of dielectric materials not only from solution, but also from the gas phase.      The hydrolysis stability of the reactive groups gives rise to better stability during storage of silane layers and permits their direct application in an aqueous medium.

Abstract: A position detection probe (1) having a magnetostrictive wire (22) stretched between a head (12) and a reflective foot end termination (28), and a magnet (20) movable along the probe (1) uses the sonic pulse propagation time from the magnet (20) to the head (12) as one parameter and the time from the magnet (20) to the foot and reflected back to the head as another parameter for determining the magnet position. The sum of the propagation times is a constant which is used as a reference value. Upon re-ceipt of the first two pulses the propagation times are summed and compared to the reference value, and the data is accepted if the sum is within a prescribed window around the reference value. When noise occurs, it creates a false measure of propagation time so that the sum of the propagation times is no longer equal to the reference value and the data is rejected.
