Title: Method and device for introducing a fluid into an exhaust-gas purificat ion system
Inventor: HOFMANN LOTHAR
IPC: F23J15/00
Filed: 1995-09-12
Abstract: Method and device for introducing liquid into an exhaust-gas purification system The nitrogen oxides emitted by an internal-combustion engine operated with excess of air are normally converted by the method of selective catalytic reduction (SCR) by bringing the nitrogen oxides, together with ammonia, into contact with a selective catalyst. In a motor vehicle, because of the dangers associated with the use of ammonia, ammonia should be carried only in the form of a substance which liberates ammonia, generally an aqueous urea solution. The problem solved by the invention consists in avoiding frost damage to sections of the exhaust-gas purification system during shutdown times and in making possible the operation of such a system at temperatures below the freezing point of the reducing agent solution used. For this purpose, the invention makes provision for the device (2) to comprise a (thermally insulated) reservoir (6) for the reducing agent liquid (4) and a liquid supply line (12) which is connected thereto and which terminates in an outlet opening (22) for the liquid (4). The reservoir (6) and the liquid supply line (12) can be heated. Furthermore, a heater (38) is provided for liquefying a starting volume (14) which is small compared with the volume of the reservoir (6). The liquid supply line (12) may also have a back-flush valve (20) to which a gas (30) which is under pressure can be applied. Said supply line (12) can consequently be blown free.

Patent CA-2211649-A1 (CA)
Inventor: TODD JOHN JAMES
IPC: B01J2/00
Filed: 1996-02-13
Abstract: Granules of plastics material have grains of an inert mineral such as sand coated thereon to provide a habitat for microorganisms effective in waste water treatment, the granules having a predetermined particle size range, and the grains having a predetermined particle size range and being disposed at a predetermined packing density range on the granules. The particles have an average density of approximately 1.0 g/cc such that a proportion tend to float and a proportion tend to sink in the waste water. The particles are manufactured by contacting the granules of plastics material with a mixture of grains of the inert mineral and grains of a soluble substance such as salt, at an elevated temperature, to coat the granules with the mixture, and subsequently dissolving the soluble substance grains from the coating to provide the granules coated with the grains of inert mineral in the predetermined packing density range.

Title: Circuit for supplying power, without the need for a battery, to the electronic control unit of a machine driven by an internal-combustion engine
Inventor: SINGER ANDREAS
IPC: H02P9/30
Filed: 1996-04-12
Abstract: The invention concerns a circuit designed to supply, without the need for a battery, the electronic control unit of a machine powered by an internal-combustion engine, in particular a hand-held machine, with a nominal d.c.  voltage (Vcc), the machine having an a.c. generator driven by the engine to produce a voltage (Ug) which is dependent on the running speed of the internal-combustion engine. The circuit (10) has a first rectifier circuit (D1, C1) which converts the generator voltage (Ug) into an intermediate d.c. voltage (Uz) which ensures that the electronics of the machine is supplied with the necessary nominal d.c. voltage, even during the start phase, without the need for additional batteries. In order to provide a simple, robustly built circuit of this kind, the invention proposes that the circuit (10) also includes first means (L, Ic2, D3, C3) which are connected downstream to the first rectifier circuit (D1, C1) and which generate the nominal voltage (Vcc) by controlled up consversion of the intermediate voltage (Uz) for as long as, at low running speeds, the intermediate voltage (Uz) is lower than the nominal voltage (Vcc).

IPC: B23Q3/18
Filed: 1997-10-14
Abstract: The disclosed invention provides a device for locating the center of an object or an opening, the device comprising an annular member defining a central hole; opposing centering plates on opposite sides of the annular member; matching opposed notches in the centering plates, said notches open towards the annular member, the apexes of said notches being in line with the center of the central hole and an equal distance therefrom. Arms on the centering plates have gears that mesh with gears on the circumference of the annular member, so that as the annular member turns, the apexes of the notches in the opposing centering plates move an equal and opposite distance along a line drawn through the apexes of the notches and the center of the central hole. To find the center of the end of a workpiece, the workpiece is placed between the notches which are drawn together to hold the workpiece, and a pointed pin is placed through the central hole to mark the center. The device may also be used to scribe a center line on a board or such, and to find the center of an opening, such as a door or window opening.

Patent CA-2220366-A1 (CA)
Title: Device for concurrent delivery of measured quantities of at least two liquids
Inventor: BYCROFT VAUGHAN
IPC: G01F11/32
Filed: 1996-05-13
Abstract: A measure (1) for dispensing measured quantities of two liqueurs from a pair of bottles has a pair of measuring receiving bowls (5, 6) associated with the bottles. Sleeves (32, 33) engage within necks of the bottles for delivery of liquid from each bottle to an associated bowl (5, 6).     Valve members (28, 29) in each bowl (5, 6) have normally open inlet liquid seals (18, 19) which cooperate with the sleeves (32, 33) to control filling of the bowls (5, 6).  Outlet liquid seals (16, 17) on the valve members (28, 29) normally close liquid outlets (21, 22) of the bowls (5, 6). An actuating lever (60) is operable to raise the valve members (28, 29), moving the seals (16, 17, 18, 19) upwardly for opening the outlets (21, 22) and closing inlets (20, 20a) of the bowls (5, 6). Thus, liquid measures flow from the bowls (5, 6) substantially concurrently into a glass or the like placed below the liquid outlets (21, 22). The outlets (21, 22) are arranged to direct the two liquids to opposite sides of the glass so that the liquids remain separated within the glass. Release of the actuating lever (60) drops the valve members (28, 29) closing the liquid outlets (21, 22) and opening the inlets (20, 20a) for recharging the bowls (5, 6).

Title: Universal wheel slip force control logic
Inventor: SCHWEIKERT DAVID E
IPC: B60T8/175
Filed: 1998-01-16
Abstract: A method in part enables a wheel  slip control  system that controls slip on a per axle basis to control slip on a per truck basis.  The wheel slip control system issues on a per axle basis an axle reduction signal indicative of a percentage by which to reduce the braking force that would normally be applied to one wheel/axle combination on a truck of a rail vehicle.  The method includes the step of converting the axle reduction signals issued on a per axle basis to a truck reduction priority signal indicative of a percentage by which to reduce the braking force on a per truck basis.   For rail vehicles featuring dynamic braking equipment another step involves commanding the dynamic braking equipment to reduce the dynamic braking force being applied to the wheel/axle combinations of the truck in response to  the percentage  carried by the  truck  reduction priority signal.   Still another step involves commanding the friction braking equipment to apply an appropriate amount of friction braking force to the wheel/axle combinations of the truck so as to resolve the slip experienced thereby.  The appropriate amount of  friction braking force  represents  the  sum of the total braking  force  sought  to  be  applied  to  the  wheel/axle combinations of the truck less first a product of the total braking force and the percentage carried by the truck reduction priority signal and less second the dynamic braking force being applied to the wheel/axle combinations of the truck.

All types of data are stored in on-line mass storage units and transferred automatically into the respective areas requesting the respective data by general data flow control components.      Requests for data can be produced manually or automatically.      Transfer times to the requesting areas or machines are shortened, the necessary premastering expenditures reduced, the mastering runs automated with aid of special control components and considerably shortened in time vis-à-vis conventional methods by the use of a network as carrier medium.
