Title: Method for coupling telecommunications terminal end points to a hybrid telecommunications system, in particular an rnt-specific telecommunications system
Inventor: KAMPERSCHROER ERICH
IPC: H04M11/00
Filed: 1997-05-16
Abstract: To couple automatically further telecommunication terminals to a hybrid telecommunications system, in particular a RNT(Radio Network Termination)-specific telecommunications system to which a telecommunication terminal is coupled, an interface structure is created in each telecommunication interface between a public telecommunications network and a DECT/GAP-specific RNT system of the hybrid telecommunications systems. Said interface structure is designed in such a manner that each telecommunications interface, independently of any other interface, forms independently further connection information relevant to the telecommunication connection for the other telecommunications units on the basis of first connection information filed in the interface and relevant to the telecommunication connection for one of the telecommunications units, for example according to a predetermined calculation algorithm.

Patent CA-2259952-A1 (CA)
Inventor: MINGHETTI ETTORE
IPC: C08K3/00
Filed: 1998-05-18
Abstract: A method of making acrylic products having a relatively even distribution of visible accent particles dispersed therein. The acrylic products are made from a composition comprising an acrylic matrix comprising a monomer rich syrup and having pre-formed particles added thereto. The pre-formed particles are evenly dispersed in the matrix by virtue of their geometry, similarity in composition or specific gravity to that of the matrix. When added with the accent particles, the pre-formed particles serve the function of restricting the movement of, and thereby suspending the accent particles in an even dispersion within the matrix. The result is an even distribution of the accent particles in the finished product.

Title: Data communication using power lines
Inventor: LEE RAYMOND
IPC: H04B3/54
Filed: 1996-09-07
Abstract: The apparatus uses electric power lines (100) to send and receive command, control, and data signal structures. Message signals are superimposed upon the AC power signals present on existing power lines (100). Transmit and receive sets (10 and 20) are equipped with a unique individual coding to complete the communication links. When a message signal is sent onto the line (100) the unique code of the sending unit (10) is placed at a predetermined position in the transmitted signal. Also the intended receiving unit code is placed in the message signal. An individual receiving network at a given location will be activated only when its unique code has been placed into a message on the line (100) sent by another unit. This coding ensures that only the intended location receiver will be able to trap the signal. The signals will be mid to high frequency and will be composed of low level logic/digital bits.

Title: Security feature comprising a perforation pattern
Inventor: ELENBAAS ABRAHAM
IPC: B42D15/10
Filed: 1997-11-04
Abstract: The invention relates to a document to be protected against forgery, comprising a security feature in the form of a perforation pattern, wherein the perforation pattern extends over a surface of the document and represents an image comprising brightness tones. The perforation pattern is herein formed such that, for instance when the thus treated document is held up to the light or placed on a light box, an image becomes visible at the location of the perforation pattern. It will be apparent that arrangement of such an image representing brightness tones requires extremely advanced technologies. Such technologies are not easily accessible to potential forgers, so that documents thus provided with such a perforation pattern are very difficult to forge. The perforation pattern is preferably applied by means of laser light.

Title: Inflatable passenger-size adjustable torso belt system including enclosure mount and method of passenger restraint
Inventor: LEWIS DONALD J
IPC: B60R21/217
Filed: 1998-03-12
Abstract: A vehicle passenger restraint system in which a belt band (16) includes a lap belt portion (20) which may or may not be inflatable and an inflatable torso belt portion (19). The torso belt portion (19) is partially mounted in an enclosure (32) which prevents substantial inflation with the remainder of the torso belt portion positioned to protect the passenger. When a large passenger buckles-up more torso belt is withdrawn from the enclosure. Upon activation of the inflator (54) with a larger passenger buckled-up, gases are supplied to the torso belt portion in the enclosure with less gas remaining in the enclosure and more gas being supplied to the torso belt portion outside the enclosure which portion protects the larger passenger.

Patent CA-2287998-A1 (CA)
Inventor: MORGAN-SAGASTUME JUAN MANUEL
IPC: C02F3/30
Filed: 1999-10-29
Abstract: The invention presents a residual water treatment plant for small flows, characterized by the combination of a primary sedimentation zone followed by anoxic and aerobic packed zones, placed serially all of them, with packing, alternating descending and ascending flows and aerated according to the oxygen requirement, there being a recirculation of treated water with sedimented mud between the secondary sedimentator and the first anoxic compartment or primary sedimentation zone, which produces treated water with enough quality for reutilization activities, after prior disinfecting (for example, watering, automobile-washing, flushing of sanitary facilities, floor-washing, and so forth). The plant requires the use of a low energy consumption air compressor, especially specified to minimize its maintenance and noise.      The treatment microplant has a compact design, which requires a small area (of the size of a water cistern for 1100L, 1.5 meters in height), and has an internal water recirculation system, preferably, of the "airlift" type, between compartments, which prevents use of rotatory equipment additional to the compressor, which recycles the accumulated mud by permitting its degradation and minimizing its unloading and production. For purposes of reutilization, the plate requires, additionally, a disinfecting unit and a treated water cistern.
