Title: Gable-top container
Inventor: WYBERG GREGORY R
IPC: B65D5/40
Filed: 1988-03-28
Granted: 1993-03-23
Abstract: ABSTRACT           A gable-top thermoplastic coated container with controllably enhanced sealing and opening characteristics includes at least one stiffening fillet attached to the panels which form the spout.  The fillet comprises a thin strip coated with a layer of adhesive, and is bonded to at least one of the pouring spout panels.  The strip is resistant to the thermal container-sealing process, and extends along a major portion of the panel length to increase the force which may be transmitted to the tip of the spout where the foldback panels are adjoined, and prevent buckling of the spout panels.  An adhesive web is delaminably bonded with a controlled release adhesive to the opposite surface of the strip, and is bonded to an opposed panel by the container sealing process. Delamination from the leakproof or hermetically sealed condition occurs at the interface between the strip and the delaminable adhesive, and is accomplished with a low opening force.  The strip provides additional stiffness to the spout panels, enabling relatively high forces to be transferred to the spout tip where the opening forces act to open the container spout.  The spout may be opened readily without significant tearing or delamination of the spout panels.

Title: Aircraft radar system
Inventor: JEHLE FRANZ
IPC: G01S7/02
Filed: 1988-05-19
Granted: 1993-04-13
Abstract: Abstract In an aircraft radar system with a search radar and a radar-warning receiver system there is an additional receiver branch, to which hostile radar signals picked up by the sharply focussed transmit-receive antenna are passed, and the output of which is connected to the radar-warning receiver.  This results in a high level of angular resolution and a considerable increase in range, and this in turn leads to the detailed and timely identification of threat situations. The use of already available components and the simple construction of the additional receiver branch means that the associated costs have been kept to a minimum.

Title: Programmable frequency identifier circuit
Inventor: GIANGANO DAVID A
IPC: G01R23/10
Filed: 1988-06-03
Granted: 1991-10-08
Abstract: ABSTRACT     A programmable frequency identifier circuit for identifing the frequency of a contaminated signal including a digital finite impulse response filter, a zero crossing detector, a zero crossing counter, and a frequency range decoder.  The filter is a programmable filter for filtering signals of the form: S(n)= S1(n) + S2(n)= Acos2.pi. F1(n) Bcos2.pi.  F2(n) where S1(n)= desire signal, S2(n)= contamination, F1= passband frequency, F2= Stopband frequency, and A,B= Constants.  The zero-crossing detector detects sign changes of the filtered signal.  The zero-crossing counter counts the sign changes occuring during a programmably determined frame time.  The number of zero crossing during the frame time is a number representing the desired frequency.  The frequency range decoder is programmed with a plurality of frequency range boundaries similarly represented by a count that is based upon the programmable frame time.  The count representing the desired frequency is successively compared to the counts representing the frequency range boundaries to identify the frequency range, if any, that contains the desired frequency.  Successively reprogramming the frequency range boundaries enables the operator to find a frequency range and then fine tune the frequency range to identify the frequency to a satisfactory precision.

Each remote controller includes a microprocessor based computer circuit which communicates over a multicar-link with the other and also over the local area networks for car and hall calls to implement an expanded control strategy with interactive program modes with least restrictive capabili-ty.  This program interacts with programs for floor control strategy and bank control strategy for the elevator system to select the best car and the most efficient operation, despite  failures which would otherwise degrade the bank operation sooner and more restrictively.

Granted: 1994-05-24
Abstract: ABSTRACT OF THE DISCLOSURE       In order to deal with echoes having exceptionally long tails, such as are generated by 2B1Q signals in ISDN systems, an echo  canceller  comprises  a  first  echo  cancelling  means, conveniently a transversal filter, operative over a first number of baud periods,  and filter means,  conveniently an infinite impulse response filter, operative over a later number of baud periods.   The filter means responds   to each symbol  of the transmitted signal to generate a pulse response which decays exponentially according to a predetermined function.  The echo canceller further  comprises means for subtracting the outputs of  the  first  echo  cancelling  means  and  the  filter  means, respectively, from the received signal.  The filter means may have more than one tap, enabling the exponential decay function to be adjusted to give a closer approximation to the shape of the echo tail.

Abstract: - 10 -                   54,091 ABSTRACT OF THE DISCLOSURE     A method and apparatus for reducing stress concentrations in a turbomachine rotor assembly are disclosed. A layer of superplastic metal is applied to a bearing surface formed on the turbine blade root. After assembly of the turbine blade to the rotor disk, the blade is pre-loaded to bring the superplastic metal layer into contact with adjoining bearing surfaces formed in the rotor disk groove. The superplastic metal material is capable of plastically deforming at least 500% thereby conforming to substantially all of the variations between the bearing surface formed on the blade root and the corresponding bearing surface formed on the rotor disk groove. By maximizing the contact area between the bearing surfaces, the stress concentractions are reduced.

Abstract: The present invention is a process for applying a semi-permeable coating on a hollow fiber substrate.  The hollow fiber substrate is continuously passed through a polymeric coating solution and withdrawn from the solution through a coating die to form a uniform polymeric solution coating on the outer surface of the hollow fiber.  The coated hollow fiber is dried by passing it through a convective flow tunnel in which the rate of drying is controlled both by a pre-determined temperature profile in the tunnel and by a controlled air flow rate through the tunnel.  The resultant material is a semi-permeable, coated composite hollow fiber membrane which can be used in gas and/or liquid separations.

Granted: 1993-09-14
Abstract: ABSTRACT OF THE DISCLOSURE     A one-piece molded plastic closure having a tamper-indicating band connected to the closure skirt by rupturable means.  The tamper band uses series of solid interiorly projecting beads that come in contact with a transfer bead on the container as the closure is unscrewed.  The engagement of the beads and container breaks the band by rupture of the connection means.  The beads in the band are arranged in tiers at three different heights on the band.  A thick cylindrical section at the bottom of the band assists initial capping.  The beads are disposed in the band at an angle equal to the pitch angle of the container threads. This eliminates need for top pressure in capping by the beads following the container thread lowering and driving the beads over the container's transfer bead locking the band in place.
