Title: Fault current limiting circuit
Inventor: CAMPBELL JOHN S
IPC: H02H9/08
Filed: 1997-04-23
Abstract: A fault current limiting circuit for limiting fault current in a polyphase electric circuit is disclosed. The fault current limiting circuit comprises a first electrical connection means for connection between a common or neutral point of the polyphase circuit and ground; and a second electrical connection means between the common point and ground. The first electrical connection means comprises an actuatable current limiting means having a first state where current will pass through the current limiting means, and a second state where current will not pass through the current limiting means. The first electrical connection means further comprises an actuating means to switch the current limiting means from the first to the second state when current through the current switching means exceeds a pre-determined maximum percentage of the steady-state load current through the polyphase system. The second electrical connection means comprises an electrical impedance significantly greater than the impedance of the first electrical connection means when the current limiting means is in the first state. The circuit is particularly suitable for use in conjunction with a three phase system that is substantially balanced. Thus, in normal balanced operation, any current flowing through the fault current limiting circuit will flow through the first electrical connection means. In the presence of a fault, any current through the fault-current limiting circuit flows through and is limited by the second electrical connection means. The current limiting and actuating means preferably comprises a fuse or circuit breaker which will pass up a selectable maximum current which may be chosen as a percentage of steady-state load current of the three phase system.
Patent CA-2203985-A1 (CA)
Inventor: SIDOROV ALEXEY IVANOVITCH
IPC: A62C5/00
Filed: 1997-04-29
Abstract: In the method for extinguishing fires in enclosed spaces, pre-cooled combustion products are introduced into an enclosed space until in the enclosed space there is an atmosphere that prevents combustion. An ecologically acceptable and fire-inhibiting medium that is not detrimental to health is formed by oxidising the combustion products completely by means of an oxygen-containing oxidising agent prior to cooling. An apparatus for implementing the method has a housing which is divided by a transversely running partition wall having at least one wall opening. At the at least one wall opening a mixing tube is mounted coaxially with respect to a discharge nozzle connected to a combustion chamber, the end of the mixing tube remote from the partition wall opening into the atmosphere. The space between the mixing tube and the inner wall of the housing is filled with a coolant. Inlet openings are formed in the wall of the housing between the partition wall and the end face of the combustion chamber facing the partition wall. The discharge nozzle is in the form of a jet pipe and extends through the wall opening into the mixing tube, a gap being present between the jet pipe and the mixing tube.

Title: Preparation of ammonium glyphosate via a gas-solid reaction system
Inventor: DAY THOMAS MCCABE
IPC: A01N57/20
Filed: 1996-03-05
Abstract: Solid N-phosphonomethylglycine or glyphosate acid in "wet cake" form is charged to a suitable mixer/reactor. A stoichiometric equivalent of anhydrous ammonia gas is fed to the mixer for direct reaction with the glyphosate acid as it is agitated within the mixer. A water jacket containing circulating water or other suitable heat transfer facilitating means readily known to those in the art is adapted to the mixer and used to remove heat from the reactor produced by the exothermic reaction. The moisture content of the glyphosate wet cake, the design of the mixer including a preferred close tolerance relation between the inner walls of the reactor and its mixing impellers together with the relative location of the ammonia gas inlet in the mixer/reactor and maintenance of a reaction temperature of about 60 ~C or below are all important process variables. The ammonium glyphosate thereby produced is a highly sorptive, water-soluble powder suitable for end use as a plant growth regulator or as a herbicide without further processing. Due to the highly sorptive character of the reaction product, however, it is particularly well-suited for further formulation to absorb/adsorb an exceptionally high level of adjuvants such as wetting agents, anti-foaming agents and, in particular, surfactants.

Abstract: Portable data medium with integrated memories is used for various purposes, for example for storing personal medical data or for storing amounts of money. The danger exists that if the data medium is lost or stolen, data or, respectively, amounts of money, are irretrievably lost to the legitimate user. In order to secure these data for the user, it is suggested with the invention to use a small terminal in addition to the data medium, with which the data medium can be connected and wherein subsequently data are copied from the data medium to the terminal. Such terminal is for example necessary in any event for specific types of data media for the operation and for displaying amounts of money. If the data medium is lost, in this case the data can be recovered from the terminal.

Filed: 1996-12-04
Abstract: The output voltage of an electrical circuit such as a Wheatstone bridge comprising four main resistors (J1 to J4) having substantially the same resistance value (R) and substantially the same temperature coefficient of resistance .alpha. is rendered insensitive to temperature differentials between the bridge arms by mounting a compensating element (r1 to r4) in each arm in series with the main resistor. Each compensating element is physically very close to a main resistor in one of the adjacent bridge arms so that it has the same temperature as said resistor. The compensating elements have the same resistance value r and the same TCR .beta., with R.alpha. = r.beta., where r is less than R and preferably r/R  1/2, in order to limit the drop in sensitivity of the Wheatstone bridge.
