IPC: B60T7/10
Filed: 2001-03-02
Abstract: Disclosed is an improved vehicle braking activation system, which provides faster response time by using a hard operated steering wheel mounted braking control system. A centralized end ball underneath a pres-sure plate within the steering wheel, depresses an underlying deformable sensing beam when force is applied by the driver on the pressure plate. The signal output of a strain gauge sensor on the sensing beam, could then provide the input for a computer to electronically control braking proportionally.

Title: Feedwater header joint assembly
Inventor: BOYD JAMES T
IPC: F16L23/024
Filed: 2001-03-16
Abstract: A joint assembly for sealedly connecting an end of a pipe or nozzle to an opening through a wall. The end of the pipe or nozzle has an annular, outwardly extending foot having a surface which rests against the wall. A bottom face of the foot has a groove which provides a lip that serves to center the pipe or nozzle in the opening. A seal weld extends around the annular foot and seals the pipe or nozzle to the wall. A flanged ring extends around the end of the pipe or nozzle for pressing the surface of the annular, outwardly extending foot against the wall and bolts or threaded studs secure the flanged ring to the wall. The joint assembly is particularly suited for use in a feedwater header joint assembly for a steam generator and, with minor modifications, can be used for sealedly connecting one or both ends of a riser pipe interconnecting a feedwater header ring to an inlet opening of a steam generator.

Patent CA-2344687-A1 (CA)
Inventor: GRIEPENTROG GERD
IPC: H02P27/02
Filed: 1999-09-10
Abstract: The invention relates to a method for measuring the speed (n) of an induction machine (2) whose stator is connected to a single- or multiple-phase AC  voltage network (L1, L2, L3) by a controllable AC power controller (4).  According to this method, the stator is disconnected from the AC voltage network (L1, L2, L3) for at least a predetermined time period (.DELTA.t) by opening the valves (6) of the AC power controller (4). During this time period (.DELTA.t), at least one stator voltage (uSX, uSY) induced in the stator by the rotary motion of the rotor is measured. The measured values are used to determine the frequency of said stator voltage (uSX, uSY) and the speed (n) of the induction machine (2) is then derived from the frequency.

Abstract: Embodiments provide methods for the protection and consolidation of calcareous materials. An exemplary method includes providing an aqueous solution of a hydroxycarboxylic acid, adjusting the pH of the aqueous solution by adding an alkaline agent, and applying the pH-adjusted aqueous solution to a calcareous mineral to form a conversion layer on the mineral. The calcareous mineral may, for example, be carbonate rock, particularly limestone and marble, or may be part of masonry material, aggregates, or fillers. Adherent conversion layers are readily formed at ambient temperatures and, therefore, methods provided are suitable for field application. Conversion layers so formed are provided as further embodiments.

Title: Thermal and reinforced refrigerator door
Inventor: BANICEVIC NEDO
IPC: F25D23/02
Filed: 2001-06-14
Abstract: A refrigerator door has reinforcing corner brackets that structurally complete the corners of the door. The corner brackets are located at the door corners adjacent vertical and horizontal side walls of the outer door skin of the door. At least one reinforcing member such as a sheet or rectangular collar, for example, or preferably reinforcing cross brace members are connected to the corner brackets. To achieve this connection and restrict heat transfer through the door and or adjacent the inner liner or in-turned flange of the outer door skin, the corner brackets have connecting tab portions that extend into the cavity of the door away from one of the side walls of the door and spaced from the other side wall of the door. The connecting tab portion is also spaced from the outer skin sheet and the inner door liner. As a result, the reinforcing member or members extend substantially across the width of the door spaced from the outer door skin wall and the inner door liner and are connected to the connecting bracket which is connected in heat transfer relation with side walls, horizontal or vertical, of the door. This reduces heat losses from the refrigerator cabinet conducted through the reinforcing member or members of the door.

Abstract: A container with pressure control device for maintaining a substantially constant, pre-set pressure in the container, which is arranged for dispensing a fluid. The pressure control device comprises a first chamber for containing a pressure fluid, in particular a pressure gas, a second chamber in which, at least during use, a control pressure prevails, and a third chamber which is formed by or is in communication with, at any rate is at least partly included in an inner space of the container. Between the first chamber and the third chamber a passage opening is provided in which a closing member is included for closing the passage opening during normal use when the pressure in the third chamber is higher than the control pressure. A control means is movable by a displaceable or deformable part of the wall of the second chamber and is arranged for at least partly displacing the closing member when the pressure in the third chamber is lower than the control pressure, such that the pressure fluid can flow under pressure from the first chamber to the third chamber. Prior to use the control means have been brought into a position in which they are at least functionally uncoupled from the closing member, and the pressure control device is arranged for functionally coupling the control means to the closing member through an activation step prior to use.

Title: Controlling engulfing and sequestering magnetic pads
Inventor: SHERIDON NICHOLAS K
IPC: G02F1/19
Filed: 2001-12-20
Abstract: Gyricon balls are provided with magnetic pole pieces that allows them to be located into two different positions by means of a further stationary magnetic pad. The magnetic pads are engulfed and sequestered from sight so they do not decrement the brightness of the display. The magnetic pole pieces are made by dispersing magnetic pigments into the polyethylene plastic. The addition of aluminum octoate to one hemisphere of the gyricon ball causes the pigmented plastic on that side of the ball to attempt to envelope the pigmented plastic on parts of the ball that does not have aluminum octoate added during the ball making process.

Patent CA-2377280-A1 (CA)
Title: Fuel and oil system for a gas turbine
Inventor: RAGO GIUSSEPPE
IPC: F02C7/06
Filed: 2000-06-21
Abstract: The invention relates to an oil pump driven by a hydraulic motor, that is itself driven by fuel pumped by a remote fuel pump through the engine fuel line. The hydraulic fuel driven oil pump is particularly advantageous for use in a gas turbine engine, to reduce dependence on or completely eliminate the auxiliary gear box (AGB) conventionally used to mechanically connect various engine systems with an engine shaft. Separating the oil pump and other fuel/oil system components from the AGB enables the rationalization of these systems and allows designers to reconfigure systems into a compact unit including the oil pump, separator, oil tank, heat exchanger and filters for fuel and oil. Using pressurized fuel to hydraulically drive the oil pump frees the oil system from location restraints and operating limitations, and permits recovery of otherwise wasted energy from the fuel bypass circuit during idling and takeoff. The close correlation between fuel flow and oil requirements eliminates the energy waste in conventional system which pump oil at rates dependant on the speed of the AGB and engine rotation.
