Granted: 1990-11-27
Abstract: Un ensemble modulaire agissant comme moniteur pour répondeur téléphonique est un appareil branché à la même ligne téléphonique que le téléphone régulièrement utilisé. Le répondeur que l'on veut contrôler est relié audit moniteur par des fiches et cordes prévues à cette fin et conçues de manière à ce que l'utilisateur puisse les raccorder lui-même. L'ensemble modulaire peut être incorporé au circuit du répondeur au moment de la fabrication. L'ensemble modulaire étant couplé à la ligne téléphonique et au répondeur, donne à l'utilisateur la possibilité de répondre au téléphone de façon habituelle pour ensuite transférer, au moyen d'un signal initialisateur, l'appel au répondeur qui prend instantanément la communication en se chargeant d'émettre un message préalablement enregistré. Le transfert de la communication se fait en initialisant l'action du moniteur comme par exemple, en appuyant sur un bouton qui démarre le moniteur tout en affichant un voyant quelconque qui, pour l'utilisateur, est la confirmation que le répondeur est bel et bien en opération, et que, de ce fait, on peut raccrocher le téléphone. Une fois le message terminé, le moniteur raccroche automatiquement la ligne téléphonique tout en retransférant au téléphone son mode d'utilisation normal. En même temps, l'affichage disparait pour indiquer à l'utilisateur que la ligne est redevenue libre, c'est-à-dire qu'elle est en état de recevoir l'appel suivant.

Abstract: A metal chimney comprised of prefabricated double-walled sections packed with compressible mineral fiber insulation material between the inner and outer metal walls. Each section has a male end and a female end constructed so that a plurality of sections can be interconnected together end-to-end and will maintain structural integrity while also reducing heat conductivity and gas leakage from the inner wall to the outer wall. The female end of each section has a flexible, diaphragm like insulation retainer and seal, while the male end utilizes a rigid spider comprised of spaced apart spoke portions between inner and outer walls in combination with an annular wafer of thin nonmetallic sheet material. After insulation, the flexible diaphragm seal is compressed against the rigid spider and annular wafer allowing the insulation to form a gas seal, which is maintained even if these wafers or diaphragm seals are consumed by chimney heat.

Date Jun. 9, 1983.A self-retaining post of a plastic material, such as PVC, for use as a roadside marking post, a traffic sign post, a lamp post, or for other comparable uses in road traffic environments, has a channel-shaped bending zone with substantially arcuate cross-section and with the convex side facing the on-coming traffic. The cross-sectional area of the bending zone increases progressively towards the lower end, whereby the flaring-out zone formed upon bending of the post will be larger below than above the line of bending. The greater inherent resiliency of the material below than above the line of bending will cause the post to bend back into an upright position after having been hit by a vehicle. Certain embodiments of the posts are manufactured by diagonally splitting lengths of extrusion-molded plastic tubing, forming two identically shaped posts from each tube length.

Abstract: A lock which is adapted to transduce the code from a key by electronic means is constructed to resemble the form and functionality of a conventional mechanical cylinder lock. A main casing 1 houses the bolt 3, a rotatable thrower or cam for retracting the bolt, an electromechanical release mechanism which normally blocks rotation of the thrower, and a processor to control the release mechanism in response to the detected key code. The electronic reading means are located in association with the keyway 26 of a rotatable barrel 25 in a cylinder unit 19 manufactured as a separate unit from the main casing 1. The thrower and barrel 25 have respective cooperating mechanical couplings 36/37 and the main casing 1 and cylinder unit 19 have respective cooperating electrical connectors 34/33. The lock is therefore assembled by attaching the cylinder unit 19 to the outside of the main casing 1, thus establishing a rotary driving connection from the barrel 25 to the thrower and establishing an electrical connection from the key reader to the processor.

Granted: 1999-05-04
Abstract: A battery operated air freshener with a housing having means for mounting the air freshener to a surface such as a wall.  A motor inside the housing is electrically connected to a fan and to a battery.  A replaceable cartridge with vents defining an air flow path carries a deodorizing substance and a battery.  The replaceable cartridge having a receptacle is positioned within the housing such that the battery carried by the cartridge fits between spaced electrical contacts connected to the motor and hence to the fan resulting in air flow through the deodorizing substance.          An anti-bootleg device in the housing has at least one prong extending into the cartridge receptacle, whereby a cartridge having an appropriate receptacle to receive the anti-bootleg device fits within the housing such that the battery carried by the cartridge fits between the spaced electrical contacts thereby establishing an electrical circuit to operate the fan.  But an anti-bootleg device in the housing with a cartridge without the appropriate receptacle precludes the battery carried by the cartridge from fitting between the spaced electrical contacts and the electrical circuit is not completed rendering the air freshener inoperative.

Granted: 1996-12-10
Abstract: When an oxide superconducting thin film is formed on a substrate by a vapor phase method such as laser ablation, for example, a plurality of grooves are formed on the substrate by photolithography or beam application in the same direction with an average groove-to-groove pitch of not more than 10 µm, so that the oxide superconducting thin film is formed on a surface provided with such a plurality of grooves.  Thus promoted is growth of crystals of the oxide superconducting thin film in parallel with the grooves, whereby respective directions of a-axes and c-axes are regulated to some extent.  This improves critical current density of the oxide superconducting thin film.

Abstract: A tensioning assembly for the stepwise tightening and releasing of a tensioning strap includes a frame (1), a tensioning lever (2), and a wind-up spindle (4) supporting ratchet wheels (3, 3').  A driving pawl (19) which is movably mounted on the tensioning lever (2) serves to rotate the wind-up spindle (4) when the strap is being tightened.          Reverse rotation of the wind-up spindle (4) is prevented by a pair of locking pawls (5, 5') which are movably mounted on the frame (1).  The lower or bearing end of the tensioning lever (2) has an unlatching cam (37) which permits the locking pawls (5, 5') to be alternatingly moved out of engagement with the teeth of the ratchet wheels (3, 3'), thus promoting safety by relieving the strap tension in stages.          An isolating cam (40) at the bearing end of the tensioning lever (2) permits both locking pawls (5, 5') to be disengaged after the strap tension has been reduced.
