Abstract: This disclosure deals with processing radio-frequency navigation signals, particularly Loran-C signals, from crossed loop antennas (H-field antennas) by shifting the signal phase from two loops to be in quadrature with respect to each other and adding them together to achieve omnidirectivity of the antenna pattern during the acquisition mode; using the stronger signal of the two during the cycle selection mode to determine the polarity of the received signals; and calculating the relative bearing angles on transmitting stations to determine, with measured bearing, the orientation of the loop antenna with respect to these stations.

Abstract: The invention embraces the incorporation of kinematic fixturing elements into cores as for the precise casting of components, where typically the cores are much softer than metal, and typically the cores are sacrificial (they are destroyed during the casting process) whereby kinematic coupling grooves are located in each of the to-be-mated surfaces of a pair of core elements, such that when a ball is placed in each of the pairs of grooves, and the elements are brought together, even with coarse axial location of the ball in the grooves, very precise relative location of the two cores is obtained; and then, when a clamping force is applied to the cores, the balls create deformation of the core grooves, and the surfaces on the two cores come together into intimate contact.

Abstract: A novel flat tubular plastic flutter valve for filling adjacent thin film evelope chambers into which it is peripherally sealed, as for cushioning and protecting items to be shipped within folder-over chambers, and in which the valve is notched to divide from a common external fluid (preferably air) filling inlet into a pair of independent flutter valve outlets one extending into each of the adjacent chambers and diverging from one another along the notch; the flutter valve preferably having low impedance characteristics imparted by a push-in and withdrawable fluid-filling block and stems that enable ready deflation and re-inflation of the chambers. The valve is also useful with other chamber bladder configurations, including undivided single chambers, among others.

Abstract: A system for achieving a high degree of damping in beams and structures made from beam-type elements such as machine tools and automation equipment, although the invention can apply to any type of structure which requires damping and/or temperature control. The invention is also concerned with utilization of the same structure to obtain a high degree of temperature control in some cases. A high degree of damping is obtained by making the beam hollow and inserting one or more structural members inside the beam along its approximate length, and then filling the annulus between the axial internal members and the external surrounding structure with a viscoelastic energy absorbing material such that the inner structures and the outer structure are fully linked in shear by the viscoelastic material so that any bending in the beams results in relative shear displacement between the beams which shears the viscoelastic material and thereby dissipates vibration energy.

Abstract: A vehicle theft prevention/security system having a concealed module capable of learning, and then recognizing the voice of the owner or authorized operator. The module controls (switches) the operation of a concealed relay that normally interrupts current to the starter solenoid or ignition system unless the owner or authorized operator speaks into a conveniently mounted microphone within the vehicle. The module may be programmed to recognize the voice of the owner or authorized user, regardless of the spoken word(s), or the module may be programmed to recognize only a certain password spoken only by a certain owner or authorized user. Once the module recognizes the owner or authorized user, the relay then switches to provide current to the previously interrupted ignition system or starter solenoid. The module provides audio output/feedback to the owner or authorized user during operation.
