Abstract: A safety seat including a crash resistent barrier to protect a small child on the lap of an adult in the even of an airplane crash. A frame including a back and a pair of sidewalls receives the bucket seat that holds the child. The frame is formed from a continuous piece of aircraft tubing bent in such a way as to form an outer oval portion and a V-shaped inner portion that provides springy resilience to the frame. A two-part crash barrier is positionable over the front of the child so that the force of an adult lurching forward will not crush the child. Seat belt receiving hooks keep the safety seat and the child securely in place on the lap of the passenger. A pair of U-shaped inflatable rings attachable around the frame keep the seat floating in an upright position if the airplane ditches over water. The two-part crash resistent barrier can be folded backwardly and locked in position so that the seat will assume one of two given angles if it is desired to use the device in an automobile.
Abstract: A multiple tone signal is demodulated and synchronization is obtained by precisely locating frame boundaries in order to ensure reliable communication in the presence of anomalies such as Doppler shift, multipath propagation, and additive electronic noise. One such signal, TADIL-A or Link-11, employs multiple tone audio waveforms that are used to modulate RF carriers for the transmission of digital data. Initially, the signal is frequency divided and classified to determine if the incoming frame is a preamble, data or noise. For preamble frames, a digital filter is used to extract the 605 Hz tone in the time domain, and the resulting real-valued signal is passed through a first Hilbert transform to generate the corresponding imaginary complex-valued signal. Unfiltered data frames are passed through a second Hilbert transform and the output is multiplied by the complex conjugate of the stored Doppler reference signal to produce a Link-11 Signal stripped of Doppler.
Abstract: A medical capsule having an outer cylinder and a piston movable in the outer cylinder, the piston being activated by an externally given signal so as to discharge a medicine to the outside of the capsule or to suck a humor for a sampling purpose, as well as an apparatus for activating this medical capsule. The capsule has a remote-controllable means including a normally-opened lead switch which connects a power supply to an activating means in response to an externally given magnetic signal thereby initiating activation of the medical capsule, whereby a simple medical capsule which is operative with minimized electrical power consumption without affecting the living body can be obtained. The activating apparatus has a pair of magnetic field generating units arranged side-by-side so as to generate magnetic lines of force in various directions and to form magnetic fields covering a large area, thus ensuring correct activation of the medical capsule inside the living body.

Abstract: A self-clinching disposable restraint or bundling strap having a locking head with a primary bore passing through the thickness of the head into which the tip of the tape is inserted and pulled through for locking. Two rows of ratchet teeth are provided on the upper surface of the tape. A front surface of the ratchet teeth forms an acute angle with the perpendicular axis of the ratchet teeth. A pair of cantilever pawls have a tip portion to exactly fit and successively engage each of the ratchet teeth as the tape is pulled through the locking head. A finger hole in the tape near the tip enables the user to readily pull the tape through the locking head.
Abstract: The present invention is directed to a vertical stacking system comprising an apparatus and method to control stack formation based on a non-contact sensing of the reaction of the feed conveyor to the forming stack. In accordance with the invention a stream of signatures is fed by the feed conveyor onto a support surface. There is an upper feed extension of the feed conveyor located above the support surface. The stack is formed between the support surface and the feed extension. The top of the stack is adjacent to the upper feed extension. The location of the extension is determined by the location of the top of the stack. The non-contact sensing means senses the location of the feed extension and generates a location signal. This location signal is used to control a slide drive which moves the support surface.

Abstract: A supersonic gas flow is employed with a virtual impactor to separate fine particles completely from the gas. The carrying gas and fine particles are accelerated to supersonic speeds and then impacted against a virtual impactor. When the supersonic stream strikes the virtual impactor, a shock wave forms in the gas stream near the impactor surface. The carrying gas turns sharply away while the particles in the gas stream, carried by their inertia, continue in their original direction and pass into the virtual impactor. On the downstream side of the virtual impactor surface, a non-contaminating inert gas maintains a pressure equal to or greater than the pressure of the carrying gas between the virtual impactor surface and the shock wave.

Abstract: A relay having a contact and terminal base assembly having a platform with mounting holes formed in corners thereof, to receive depending limbs which extend from the coil and plunger assembly so that, in this way, the two assemblies are mechanically engaged by a socket-type connection. Each assembly, then, may be separately manufactured, to support the contacts and terminals in the one assembly, and to support the coil and plunger in the other assembly, respectively; then, the two are socketed together, to form the complete relay. Such modular construction simplifies manufacturing, and facilitates final, factory adjustments, of each module-assembly, before the two are mechanically joined.

Abstract: An oral hygiene device employs a hollow plastic tube sealed at both ends. At least one area along the length of the tube is weakened and has its diameter in the weakened area reduced, but not reduced to zero diameter. A length of fiber, such as conventional dental floss well known as a tooth cleaning material is stored within the length of the tube comprising the housing and has each of the free ends secured to a bulk of rigid material whose size does not permit the fibrous material from being able to escape the narrow diameter area. In use, a user bends the unbroken tubing housing to a point that the tubing breaks into at least two pieces, allowing the fibrous flossing material to be positioned intermediate the separated portions of the tubing, which are now free to act as handles. After its use, the fibrous material and the two handles may be discarded.
Abstract: Amines in which the amino group is on a secondary carbon atom which is chirally substituted can be enantiomerically enriched by the action of an omega-amino acid transaminase which has the property of preferentially converting one of the two chiral forms to a ketone. The process can be used to stereoselectively sythesize one chiral form from ketones substantially to the exclusion of the other. An aqueous solution of chiral amines after being brought into contact with an omega-amino acid transaminase and an amino acceptor is treated with a water-immiscible organic solvent, the aqueous and organic phases are separated, and the aqueous phase can be recirculated for further contact with the transaminase.
