Title: A method in a subscriber line interface circuit as well as a subscriber line interface circuit
Inventor: ISRAELSSON MATTIAS
IPC: H04M19/00
Filed: 1998-05-28
Abstract: In a subscriber line interface circuit (1) connected to a two-wire telephone line (A, B) for transmitting AC signals, one (A) of the wires is set to a high DC voltage lower than a first DC voltage (GND), while the other wire (B) is set to a low DC voltage higher than a second DC voltage (VREG). First means (10, 11) are provided for setting, for AC signals on said one wire (A), a first threshold voltage (VTHA) between said first DC voltage (GND) and said high DC voltage, and/or, for AC signals on said other wire (B), a second threshold voltage (VTHB) between said low DC voltage and said second DC voltage (VREG). To automatically adapt the signal headroom to the actual amplitude of the AC signals, second means (2, 3, 4, 5) are provided for controlling the voltage difference (VA) between said first DC voltage (GND) and said high DC voltage and/or the voltage difference (VB) between said low DC voltage and said second DC voltage (VREG) as long as the instantaneous value (va) of the signal on said one wire (A) equals the first threshold voltage (VTHA) and/or the instantaneous value (vb) of the signal on said other wire (B) equals the second threshold voltage (VTHB).

Abstract: Apparatus for inflating an air bag (16) and for reducing the inflation rate of the bag (16) in the event hat an occupant of a vehicle engages the bag (16) before it is fully inflated, comprising a gas generating unit (14) for producing an inflation gas in response to a predetermined impact to the vehicle, and an aspiration unit (12) connected to the gas generating unit (14) and to the bag (16). The aspiration unit (12) comprises an ambient air inlet (22), a mixing chamber (28) in communication with the air inlet (22), and nozzles (32) in communication with the gas generating unit (14) and the mixing chamber (28) for directing inflation gas into the mixing chamber (28) to aspirate ambient air through the air inlet (22) into the mixing chamber (28) so that a mixture of ambient air and generated inflation gas is created for the inflation of the bag (16). Upon engagement of the bag (16) by the occupant before it is fully inflated, a back pressure is created in the mixing chamber (28) to reduce or terminate the flow of aspirated air into the mixing chamber (28) and thus to reduce the inflation rate of the bag (16), thereby preventing continued rapid inflation of the bag (16) and possible serious injury to the occupant.
Patent CA-2294200-A1 (CA)
Inventor: BLACKMORE JOHN M
IPC: C08B37/00
Filed: 1998-05-28
Abstract: The present invention relates to improved methods for making and using bioadhesive, bioresorbable, antiadhesion compositions made of intermacromolecular complexes of carboxyl-containing polysaccharides and polyethers, and to the resulting compositions. The polymers are associated with each other, and are then either dried or are used as fluids. Bioresorbable, bioadhesive, antiadhesion compositions are useful in surgery to prevent the formation of post-surgical adhesions. The compositions are designed to break down in-vivo, and thus be removed from the body. Membranes are inserted during surgery either dry or optionally after conditioning in aqueous solutions. The antiadhesion, bioadhesive, bioresorptive, antithrombogenic and physical properties of such membranes can be varied as needed by carefully adjusting the pH of the polymer casting solutions, polysaccharide composition, the polyether composition, or by conditioning the membranes prior to surgical use. Bi- or multi-layered membranes can be made and used to provide further control over the physical and biological properties of antiadhesion membranes. Antiadhesion compositions may also be used to deliver drugs to the surgical site and release them locally.

Patent CA-2310839-A1 (CA)
Inventor: CUNDLIFFE VIVA
IPC: C10G27/12
Filed: 2000-06-05
Abstract: This 50-30,000 barrel tank is a facility to Oxidize and Purify a variety of fuels using Hydrogen Peroxide (in 30%-99% purity) before the fuel is sent to market. The attachments and scheme are designed in an open air fashion so that the Hydrogen Peroxide can not cause a pressure buildup as it performs its oxidation process on the fuel. The roof is designed to protect the contents of the tank from weather, and, hold sealed lighting for the work area. The Grid Iron work area is of sufficient size ( covering about 25% of the top of the tank) to allow for two to three persons to perform the tank operations, which are to receive the barrels, measure the Hydrogen Peroxide, and operate the mixer as the Hydrogen Peroxide is added to the fuel. After the Fuel stands in the tank for 24 -48 hours, it will be suctioned out to a preliminary or final storage tank or taken on beard a tanker truck for market. There will be a nominal amount of water and dust settled at the bottom of the subject tank, which will be hosed out of the tank at its lowest corner, and put into barrels, and shipped in water to a handling facility. The tank will be constructed of a sufficiently strong combination of Re-bar concrete and Metallic or Plastic lining (non-reactive surfaces for the Hydrogen Peroxide).  There will be a covered electric or gas motored lift shaft to the side of the tank for bringing the Hydrogen Peroxide barrels from ground level to above the top of the tank, or a separate tank holding the hydrogen peroxide from which it will be piped into the tank, where it will be administered to the fuel in measured quantities.
