Abstract: The gene encoding GDP-L-fucose: .beta.-D-Galactoside 2-.alpha.-L-fucosyltransferase has been cloned, and a mutation in this gene has been found to be responsible for an individual being a non-secretor.

Abstract: An apparatus to be employed within a precision distance measuring system for estimating pulse time-of-arrival. The apparatus facilitates the use of an Adaptive Fixed Threshold method for such estimation. The invention compensates for pulse time detection errors induced by variations in incident pulse amplitude and shape by adjusting the estimated time-of-arrival. This adjustment is performed as a function of the measured pulse slope between two low-amplitude threshold levels through the use of a predetermined reference table of error adjustment times.

Abstract: A method and means for monitoring a Microwave Landing System (MLS) that provides statistical independence of the monitoring process from the MLS to insure the integrity of the MLS signal format. The r.f. signal transmissions are received by a monitor receiver and down converted to i.f. signals. The i.f. signals are decomposed into in-phase (I) and quadrature (Q) components. The I and Q components are applied to a digital signal processor that derives all synchronizing information from the I and Q components and that effectively reconstructs the complete MLS signal format from the I and Q components. The reconstructed signal format is compared with predetermined standards and an alarm is generated if the reconstructed signal format is out of tolerance. The integrity of the monitoring process is insured by periodically substituting i.f. signals that simulate the MLS signal format but that are out of tolerance.

Abstract: A method for obtaining the far field pattern of a phased array MLS antenna using measurements by a monitor located in the near field of the MLS antenna. The near field pattern differs from the far field pattern because of the presence of phase error terms in the measured near field pattern. The method comprises computing the Fourier transform of the complex conjugates of the phase error term of the near field pattern and convolving that transform with the measured near field pattern to obtain the far field pattern.

Abstract: A tool formed as telescopic longitudinal member having a V shaped end piece acts as a retrieval tool for fishing lures caught on objects under the water. The V-shaped piece has a surmounting hook like member, that is removable, for the convenience of stowing but in operation acts as the guide means along which the hook member travels on the fishing line as the rod is pushed down the fishing line to disengage a caught lure below.

Abstract: A modem use monitor (MUM) is disclosed which is utilizable with one or more groups of modems for analyzing modem defects of the individual modems. Typically, a rotary hunt arrangement of telephone lines for data communications is sequentially served by several modems. For analytical purposes, an intercept device is provided to receive a data carrier detect signal from each modem. The intercept device has been enhanced to receive a plurality of signals and to facilitate defect analysis. Exemplary of the processed signals is the summing of the ring indicator (RI) signal and the data carrier detect (DCD) by means of a logical OR to provide a single test signal which can be examined for a ring-no-answer condition.

Abstract: Method and means for monitoring the performance of a phase array antenna. The antenna comprises an array of individual radiating element seach of which radiates a prescribed proportion of the energy to be transmitted thereby shaping such energy into a beam. Individual phase shifters are associated with each radiating element, the phases of which control the direction of the beam pointing. The method of the invention involves sampling the beam by means including a single receiver located along a fixed radial from the array. The beam scans at a constant rate. The samples are collected at non-uniform intervals of time during a beam scan. The samples are, however, separated by equal increments of arcsine .theta., where .theta. is the pointing angle of the beam. The samples are analyzed by means including a Fourier transform to provide the value of the amplitude and phase of the signal radiated by each of the radiating elements.

Abstract: A position estimator for determining the position and velocity of a moving platform in cooperation with radio navigation aids is described incorporating an unbiased estimator, such as a least means square estimator, a biased estimator for determining the angle of inner section of the lines of position from the radio naviation aids for determining the liklihood of geometric dilution of precision (GDOP) and a switch for selecting the estimate of position and velocity from said biased estimator at first times and the unbiased estimator at second times. The invention overcomes the problem of accuracy degredation associated with a nearly collinear measurement geometry which causes the variance of the position estimates to be higly inflated.

The intercept device has been enhanced to receive a plurality of signals and to facilitate defect analysis.

Abstract: A modem use monitor (MUM) utilizable with one or more groups of modems is disclosed which modems, in turn, serve a rotary hunt arrangement of telephone lines for data communications. For analytical purposes, for each modem there is an intercept for providing a data carrier detect signal to central processor. The monitoring of the signal is provided on a periodic basis, generally every five seconds, and an indication of such response is provided periodically, generally each minute. The modems within each group are numbered and have correspondingly numbered registers for storing the responses for each modem in number sequence. The central processor has the additional function of examining the registers upon acquisition of each response and ascertaining if all modems lower in the numbered sequence have an indication of data carrier detect present.

Abstract: A set containing an odd number N of successive raw range data samples from precision distance measuring equipment is established. The set is arranged in ascending order of sample magnitude. The median member of the ordered set, i.e. the (N-1/2+1 member, is selected for processing in an alpha-beta type digital filter. The filter output is compensated for the delay introduced by using the median member of the set as the input to the alpha-beta filter. The compensated filter output is utilized as the distance input signal to a display or aircraft flight control system.

Abstract: A unitary shingling apparatus prepares uniformly shingled sets of forms from a continuous, preprinted roll. The apparatus numbers the individual forms in groups of predetermined count, wherein the forms in each group receive identical numbers. Each group is then shingled into its own set. The forms are numbered while still on the web, then separated from the web by a reciprocating knife, transported individually to a predetermined indexing position, and then transferred, glued and shingled onto a shingling conveyor in the shingled, overlapped sets.

Abstract: Paperstock pieces coated with a thermoplastic resin are introduced into and agitated together in a pool of hot, saturated vapors of a liquid, halogenated hydrocarbon capable of wetting the resin. The vapors condense on the resin surface and the resin is loosened and removed by the combined actions of the agitation and of the vapors and condensate.

Abstract: A control rod driven in correspondence with another regulating device may be independently extended to different positions corresponding to a selected condition while the other control arm remains at a fixed length and moves in correspondence with the driving means.

Abstract: A shaped polyester article having a rubber latex-polyepoxide-polyisocyanate-phenol-formaldehyde adhesive coating is obtained by the addition of compounds containing at least one of the following metals: sodium, potassium, rubidium, cesium, strontium, silver, cadmium, barium, cerium, uranium, titanium, vanadium, chromium, tin, antimony, manganese, iron, cobalt, nickel, copper, zinc, lead, bismuth, calcium and zirconium to the adhesive prior to the deposit of the adhesive coating on the polyester. The use of said metals in said adhesive composition allows the use of less adhesive to achieve the same degree of adhesion as when an adhesive containing no metal-containing compound is used.
