Abstract: Anionic clay compounds such as hydrotalcite-like compounds can be made by a process wherein a non-hydrotalcite-like compound (or a hydrotalcite-like compound) are heat treated and then hydrated to form hydrotalcite-like compounds having properties (e.g., increased hardness and/or density) that differ from those of hydrotalcite-like compounds made by prior art methods wherein non-hydrotalcite-like compounds (or hydrotalcite-like compounds) are not similarly heat treated and hydrated to form such hydrotalcite-like compounds.

Abstract: Smart cards having high quality external surfaces can be made through the use of partially cured, low shrinkage glues to hold the smart card's electronic elements during their immersion in a thermosetting material that becomes the core layer of said cards. Mounds of low shrinkages give serve to hold the electronic component in a given position in the core layer.

Abstract: A gang form for use with a concrete form system. The concrete form system has a plurality of said gang forms and a plurality of tie rods. An improved insert having four sides is positioned between two adjacent form panels having flanges with flange openings therein. Side openings in the third and fourth sides of the insert are aligned with the flange openings. Attachment devices are inserted in the side openings and flange openings to attach the insert to the two adjacent form panels and to provide the gang form. At least one lock member is rotatably attached to the second side of the improved insert. One of the plurality of tie rods extends through a tie rod opening in the first and second sides of the insert and is firmly secured to the insert by moving the lock member from an unlocked position to a locked position. Thus, the gang form is interconnected to the concrete form system.

Abstract: An apparatus and method are disclosed to force a frozen food product out of a receptacle by moving a piston back and forth within the receptacle. Pressurized air is used to move the piston toward the frozen product, thereby forcing the frozen product out of the receptacle. To move the piston away from the frozen product, the pressurized air is sent through a venturi that also connects to the receptacle. The flow of pressurized air through the venturi creates a vacuum in the receptacle. The vacuum pulls the piston away from the frozen product.

Abstract: A stabilizer platform mounted to a vessel for positioning a satellite dish antenna in the azimuth and elevation directions. An azimuth motor and an elevation motor are mounted in a formed hollow interior of a housing. Azimuth motor control cables and elevation motor control cables are connected to the motors to carry signals and power for controlling the operation of the motors. On top of housing is mounted a platform which rotates in the azimuth direction with respect to the housing. The azimuth motor is coupled to the platform through a gear arrangement and rotates the platform. On top of the platform is mounted an elevation drive which holds the satellite dish antenna. Mounted in the platform is an elevation gear cluster which rotates with respect to the platform. The elevation gear cluster is coupled to the elevation drive. The elevation motor drives the elevation gear cluster so that the elevation motor can move the satellite dish antenna in the elevation direction.

Abstract: An optical cross-connect network provides wavelength routing of optical channels between two arrays of optical fibers carrying WDM signals using interconnected arrays of optical wavelength switches based on combinations of a 1.times.2 wavelength switch architecture. The cross-connect network can be made by interconnecting two arrays of 1.times.4 wavelength switches, each of which is made by combining three 1.times.2 wavelength switches. Each 1.times.2 optical wavelength switch includes a polarization separation element that decomposes and spatially separates the input signal into two orthogonally-polarized beams, and a wavelength filter that decomposes into the beam pair into two pairs of orthogonally-polarized beams that carry a first spectral band at a first polarization and a second spectral band at an orthogonal polarization. A polarization-dependent routing element spatially separates these four beams into four orthogonally-polarized components.

Abstract: A post-processing system for an optical correlator automatically detects and ranks peaks in the correlation image. An array of input buffers each receive pixels from a predetermined region of the image from the correlator camera. An array of peak detectors search the image pixels in each region for correlation peaks exceeding a predetermined threshold figure of merit. For example, each peak detector can be convolver array and a local maximum detector. The peak detectors generate a report entry for each such correlation peak that contains the figure of merit and location of the peak within the image. Results sorting and reporting means collect and store the report entries from each peak detector. The report entries are sorted by their figures of merit and reported to the host computer system.

Abstract: An on-demand teleconferencing system and method for setting up an on-demand conference call in a telecommunications system having the Advanced Information Network (AIN) architecture with system signaling the number 7 (SS7) and a Public Switched Telephone Network (PSTN). A subscriber is assigned an on-demand conference call number. When that number is dialed into the PSTN, it is identified by the PSTN that the dialed number requires handling by the SS7. The SS7 links the dialed number to a conference allocation and control system (CACS) which is connected to a plurality of scalable bridge servers. The CACS selects bridge servers available to handle the conference call and based upon a selection criteria such as a peak load sets up the on-demand conference call in one of the selected bridge servers.

Abstract: A programmable wavelength router having a plurality of cascaded stages where each stage receives one or more optical signals comprising a plurality of wavelength division multiplexed (WDM) channels. Each stage divides the received optical signals into divided optical signals comprising a subset of the channels and spatially positions the divided optical signals in response to a control signal applied to each stage. Preferably each stage divides a received WDM signal into two subsets that are either single channel or WDM signals. A final stage outputs optical signals at desired locations. In this manner, 2.sup.N optical signals in a WDM signal can be spatially separated and permuted using N control signals.

Abstract: A LED matrix display having a variety of enhanced functionalities including: a scheduler which schedules tasks based upon commands correlated with real time; a tracking and accounting procedure which provides a database file which accounts for tasks as a function of the time a task is performed; sports display presentations of various sports information associated with different sports based upon corresponding sports IDs; the use of virtual display images or windows which may vary over time and which overlay template or faceplate images; and an improved error reporting capability in which detected errors are displayed using clear descriptive text information.

Abstract: An endotracheal tube can be inserted into a patient's trachea during resuscitation by using a face mask and a curved guide. The guide is inserted through a flexible port in the face mask and has a curved distal portion that extends into the patient's mouth and hypopharynx. The patient is initially resuscitated by supplying a flow of air/oxygen through the mask. An endotracheal tube is inserted over the distal end of a fiber optic probe. Resuscitation, oxygenation, or artificial ventilation continue without interruption while the fiber optic probe and endotracheal tube are inserted through a flexible port at the proximal end of the curve guide and then advanced along the guide into the patient's airway. The direction of the distal tip of the fiber optic probe can be controlled by the physician. This allows the physician to carefully guide the fiber optic probe and endotracheal tube to a position past the larynx while resuscitation continues.
