Title: A condition-adaptable colored fishing net
Inventor: JOVANOVICH JOHN
IPC: A01K75/00
Filed: 1998-10-21
Abstract: A condition-adaptable fishing net designed to catch more fish. The fishing net includes a single, large panel of netting having a main, light color capable of blending in water under certain water and lighting conditions. Disposed randomly over the panel of netting are a plurality of various sizes and shapes of colored areas, each having a color selected from a group of colors, all capable of blending in water under different water and lighting conditions. By randomly creating different colored areas over the net panel, what fish will believe to be holes or barrier free areas, appear randomly in the panel of netting. During use, the different colored shapes randomly appear as holes or barrier free areas in the panel of netting through which the fish then attempt to swim, thus becoming entangled in the net.

Title: Flexible, multiple-compartment drug container and method of making and using the same
Inventor: WALTER WILLIAM V
IPC: B31B50/64
Filed: 1997-04-11
Abstract: A flexible container (10) is provided for the storage and mixing together of diluents and medicaments. The container incorporates multiple compartments (18, 22), separated by peeled seals (24, 26), in which the diluents and medicaments are stored. The container is constructed of thermoplastic materials having high oxygen and moisture barrier properties which allows the container to be stored for extended periods of time without degrading the contents. The seals are ruptured by manipulation of the container to thereby mix the contents together for delivery through standard IV arrangement to a patient. The seals are constructed to provide a non-linear resistance characteristic to hydraulic pressure, which causes the seal to peel open completely along its length. The container also includes a locking tab (28) and retaining slot (27) to secure the bag in a folded over condition.

Title: Process for preserving dead leaves and make them usable within various objects such as but not limited to magnets, cards, bookmarks, collages, sculptures, mobiles and advertising media
Inventor: VAN DONGEN-VOGELS VINCENT
IPC: A01N3/00
Filed: 1998-11-27
Abstract: Dead leaves can be extremely beautiful. Think of the color of the maple leaves in the fall. In Canada, the maple leaf is an important symbol. It appears on the Canadian flag and on many objects. The problem with dead leaves is that they are extremely hard to preserve. To be properly preserved, they cannot be in contact with air and humidity. The typical technique to preserve them is to keep them flat in a book. They can also be kept in formalin or be varnished. In this invention, a new process effectively preserves dead leaves. The process consists of two steps.  First, the moisture in the dead leaf is removed by keeping the leaves flat in a portfolio. The second step consists of laminating the leaf using a pouch laminator. The leaf is first inserted in a plastic pouch and the laminator is preheated. The pouch is then inserted in the hot laminator and as a result, the leaf is completely embedded in the pouch. The plastic coating fully protects the leaf from air and humidity. The laminated dead leaf can therefore be preserved and be used for all kinds of objects :  magnets, cards, bookmarks, collage, sculptures, mobiles, etc. As a variant, messages can be added to the leaf in the plastic pouch and laminated with the leaf.

Title: Method for optimal selection among multiple providers in a wireless communications service environment
Inventor: PRISE MICHAEL EDWARD
IPC: H04W60/00
Filed: 1997-06-24
Abstract: A communication device locates a preferable wireless service provider in a multi-service provider environment using a frequency band search schedule. Initially, the communications device registers with a less preferred service provider in a first frequency band. While remaining registered with the less preferred service provider, the device examines several frequency bands in the order specified by the frequency band search schedule. A frequency band is examined by dividing the frequency band into many sub-bands, and by locating the strongest signal above a threshold within the sub-band being examined. The examination continues until a second frequency band having a more preferred service provider is located. The communication device then registers with the more preferred service provider. The order of search of the frequency spectrum may be based upon registration history of the communication device.

Abstract: In this invention the light is projected to the keyhole directly by pressing a small finger press switch that is installed on the key-grip. This model is made in such a manner that the key grips of any key can be taken away and be replaced by the lighting key-grip. In other words, it is possible to convert any key to a lighting key. In future models of the lighting key, I have designed to use re-chargeable batteries that will feed charge from any electrical source nearby or connected to the concerned key. One example is the car key, were the key has to be in the starter at all time "while the engine is running". The lighting key can recharge itself for the period of time that the key is in the keyhole.  In the present model, I have used coin battery as the source of electricity. The functions are exactly the same. In the more extended models of this lighting key I have designed to have lighting diod of round shape that will shed a greater and smoother light on the keyhole. The color of light is the distinguishing factor of rights of manufacturing to the buyer. Which means, different companies can learn and buy the right to manufacturing of the lighting key in distinguished colors.
