Title: Low frequency air mass perturbation detector using a sealed volume flexible tube as the containment medium
Inventor: SINGMIN ANDREW
IPC: G01H3/06
Filed: 1994-09-04
Abstract: It is common in industrial and military scenarios for large tracts of real estate to be monitored for the illegal removal of equipment by intruders.      Most   commonly,   closed   circuit   video cameras/recorders, pressure transducers, buried below ground radio wave cable based protection systems, microwave, laser, infra-red and ultrasonic surveillance systems are deployed to guard against this threat.  They all work to some extent in providing protection, but cost escalates sharply as the area to be protected grows and the level of protection required is expanded.          This invention focuses on the ability to provide a lower cost alternative to these options, for situations where a large tract of land has to be monitored for surface movement, i.e. either from human traversal or equipment movement into/out of the protected zone.  The novel detection concept is based on the principle of electronically detecting the very sensitive perturbation of the intrinsic  air mass within a closed  length of small diameter flexible plastic tubing, arising as a result of physical vibrations being  applied  to  the  ground  above  the  buried  tubing.    A mechanically modified electret microphone insert,  coupled with electronic  processing  circuitry  incorprating  very  low  pass filtering and variable threshold discriminators, enables detection of the required signal only and rejection of unwanted audio level signals.          This invention lays claim therefore to be able to detect at a relatively lower cost than current detection systems, utilizing relatively simple processing circuitry,  very small changes  in physical movement/vibration to the ground immediately above the buried plastic tubing.  Unlike pressure transducers, this invention detection the very small shift in movement of the intrinsic air mass contained within a sealed length of flexible tubing.   The shifting air mass occurs at a very low frequency.  The claim is uniquely novel since no other like detection method is known to exist or be reported to exist.

Title: Highly active zsm-5 zeolite and process for producing the same
Inventor: FUJISAWA YOSHIKAZU
IPC: B01J29/46
Filed: 1994-09-26
Abstract: ABSTRACT OF THE DISCLOSURE       A highly active ZSM-5 zeolite has an irregular ZSM-5 type  crystal  structure   depleted  of  some  of forming elements in a lowly active ZSM-5 zeolite  having a regular ZSM-5 type crystal structure. The single-lattice volume V1 determined from crystal lattice constants by an X-ray diffraction for the irregular ZSM-5 crystal structure is in a relationship of V1 < V2 with a single-lattice volume V2 determined from crystal lattice constants by an X-ray diffraction for the regular ZSM-5 crystal structure.  This is attributable to the fact that a relationship of .beta. > .alpha. is established between Si-O-Si bond angles  .alpha.  and  .beta.  in the regular and irregular ZSM-5 type crystal structures. Such a highly active ZSM-5 zeolite has a high activity and a high heat-resisting temperature.

Abstract: A tubular plastic bird feeder is made from a unitary blow molded enclosure which includes engageable thread patterns on one end cap and the adjacent end of the tubular body which are separated in molding by an integral annular sleeve.  The sleeve is cut away circumferentially at both ends from the as-molded enclosure leaving a separated end cap which may be threaded onto the end of the tubular body.  Similar integrally molded thread patterns may be formed on the other end of the unitary enclosure to provide either another removable end cap or the facility to thread another tubular body onto the end of the first tubular body to provide an extended length feeder.  One embodiment includes a circular barrier disc supported in the tubular body below the lowermost seed holes to pre-vent seed, and other particles from accumulating in the inaccessible lower end of the feeder.  In lieu of conven-tional seed holes cut, punched or otherwise formed in the tubular body, the body may be formed in the blow molding process to include angled seed ports with protective deflector hoods.  Another embodiment includes internal and external thread patterns on one end of the tubular body to accommodate either of two seed tray constructions.

Patent CA-2157959-A1 (CA)
Title: Appareil et methode pour synchroniser une station de base et une unite portative appelee a fonctionner dans un systeme a saut de frequence
Inventor: TAM HERBERT W
IPC: H04B1/7156
Filed: 1995-09-11
Abstract: Un téléphone sans cordon conçu pour fonctionner dans un système à saut de fréquence établit rapidement des communications entre une unité de base et un combiné associé faisant partie du téléphone. La synchronisation entre l'unité de base et le combiné est réalisée au moyen d'un processus lors duquel l'unité de base envoie un message de début de saut de façon contiguë pendant un nombre donné de trames ou d'intervalles de temps. Le combiné répond en envoyant un accusé de réception de ce message à l'unité de base dans une trame chaque fois qu'il reçoit ledit message dans une trame. En réponse à l'accusé de réception envoyé par le combiné, l'unité de base envoie à son tour au combiné un accusé de réception, également pendant un nombre donné de trames. Si soit l'unité de base, soit le combiné ne reçoit pas un message dans une trame donnée, le processus de synchronisation se poursuit de façon avantageuse car chacun des messages contenus dans le nombre donné de trames décroît linéairement en valeur d'une trame à la suivante. Ainsi, l'unité de base et le combiné sont capables de prévoir la valeur de chaque message non reçu dans une ou plusieurs trames données. Par conséquent, lorsque le combiné reçoit l'accusé de réception de l'unité de base dans au moins une trame, l'unité de base et le combiné sont synchronisés et commenceront le saut de fréquence lorsque la valeur de ce message décroîtra linéairement dans le temps pour atteindre un niveau prédéterminé. Si les communications en cours entre l'unité de base et le combiné sont interrompues par mégarde, le téléphone sans cordon rétablit rapidement les communications dans le système à saut de fréquence au moyen du même processus de synchronisation.
