Abstract: An Internet-based directory information system for providing toll free telephone numbers and other company information based on product or service advertising. First and second web sites are configured with separate first and second graphic user interfaces for the entering of company information and search request information, respectively. A database correlates entered company information (including toll free telephone number) to advertising information, compares the company-provided advertising information to a search request-provided advertising information, and formulates a search result based on matches between the search request and the company-provided advertising information.

Abstract: An accessory for bicycles or tricycles for producing a motorcycle-like sound appealing to youngsters. The device being constructed of a strip of relatively hard but flexible material formed into a shape having: a flat region (32) engaging the spokes of the bicycle wheel; an "S" shaped region (28) providing flexibility thereby allowing the flat region to move as the spokes impinge on it; a semi-tubular region (30) lined with a hook type fastener material for attaching to a fork element of the bicycle; and a handle (34) as an aid for spreading apart the semi-tubular region to attach the accessory to the fork element.

Abstract: A gas line safety evacuation apparatus and method wherein earthquakes or other hazardous disruptive events are monitored and detected. Upon detection of an earthquake or like event, gas or other fluid lines are evacuated by an evacuation pump, and the evacuated gas is stored in a storage tank for future use. Control valves are activated upon detection of the earthquake to prevent additional gas or fluid from entering the lines.

Abstract: A article of manufacture and composition for preventing a tear, hole or run in hosiery from expanding, wherein the composition comprises:(a) nitrocellulose,(b) resin,(c) dioctylphthalate, and(d) a solvent or solvent mixture.

Abstract: A fertility period calculator especially suited for third world countries, non-complex in operation, having two rotatable disks that require identification of numerals representing the days of the month and the average number of days in the user's menstrual cycle.

Abstract: The invention relates to an apparatus for treating a particulate thermoplastic material.This apparatus comprises a container (1) divided internally by a perforated partition (12) which serves as a passage for a purging gas. A suitable rotor (6) provided with blades (10) and (11) allows the treated charge to be maintained temporarily at a distance from the stationary and rotating internal walls of the apparatus.The invention applies especially to the coloring of particulate plastic materials by coating.

Abstract: High definition television (HDTV) signals are broadcast in a manner to be compatible with television receivers that operate to reproduce standard definition images, and the broadcast HDTV signals are contained within an existing frequency band in the electromagnetic spectrum allocated for transmission of the standard definition images. An image to be broadcast is scanned with a high definition camera capable of producing an image frame of N lines of resolution, wherein N is equal to about twice the line resolution of a standard definition image frame. The camera produces N/2 odd line image signals and N/2 even line image signals for each image frame. The odd line signals are modulated on a radio frequency (RF) carrier wave to produce HDTV odd line image signals occupying at most the same frequency band in the electromagnetic spectrum as occupied by standard definition images.

Abstract: The invention covers the control of the horizontal position of a reamer cutting tool in relation to a tool-holder pin.A support is surmounted by a core which slides sideways in the pin. The slide is controlled by a screw whose head forms a vernier, while its crown wheel is engaged tangentially by a worm screw. A flange holds the whole mechanism in place horizontally. A locking screw locks the support into position once an angle has been fixed.The invention has the following features: reduction in the overall diameter of the tool; and increase in precision by the suppression of action which would interfere with the precision adjustment and throw it out of tolerance at the moment the device is finally locked into position.
