Patent number: 6427410Abstract: A device (10) for fixing facing panels (14) to a wall (16) by means of a transverse support (12), on which the facing panels (14) can be suspended. To render the transverse support (12) stable, the invention proposes constructing the transverse support (12) as a closed, hollow profiled member. This has the advantage that even heavy facing panels (14) can be mounted on the wall (16). Moreover, the invention proposes vertical supports (32) for mounting the transverse support (12), which are to be mounted on the wall (16) at a distance therefrom by means of length-adjustable rods (42), which are pivotally connected to the vertical supports (32) and to the wall (16). A single rod (42) forms a movable bearing (40) and two rods (42) mounted at an angle to one another form a fixed bearing (38). The advantage of this method of mounting the transverse support (12) on the wall (16) is the ease of vertical adjustment and ease with which wall unevenness can be accommodated.Type: GrantFiled: September 30, 1999Date of Patent: August 6, 2002Assignee: Fischerwerke Artur Fischer GmbH & Co. KGInventor: Stefan Lind

Patent number: 6427411Abstract: A bumper and supporting frame assembly for protecting a column or a corner, or any object which may come in contact with the column or corner. The invention includes tires having hubs or wheels rotatably mounted on a sleeve, i.e. a hollow tube. A pair of frames for mounting around a column, one above the tires and the other below the tires, support the tires in their position as bumpers to protect the column. The frames have tubular protrusions, e.g. pipes, extending towards one another and telescopically engaged. The sleeve is rotatably mounted on the pipes. Energy from an object which strikes the column is dissipated by this rotation of the sleeve relative to the pipes, as well as the rotation of the tires relative to the sleeve. Each frame includes two portions, which are removably attached to one another, allowing for the easy adjustment of the frames along a column. The adjustment of both frames allows for the height of the bumper to be varied on the column.Type: GrantFiled: January 10, 2001Date of Patent: August 6, 2002Inventor: Randy E. Shows

Patent number: 6427442Abstract: A hydrostatic transaxle axle assembly for a vehicle such as a grass mowing lawn or garden tractor comprising a housing for an internally disposed hydrostatic transmission having a variable-displacement hydraulic pump fluidly connected to a fixed-displacement hydraulic motor, the hydraulic motor being connected by differential gearing to axle shafts supported in the housing. The housing is formed by three housing members, two of which are preferably separable on a parting plane coincident with the longitudinal axes of the axle shafts. One of the housing members being provided with an opening to allow a portion of one of the other housing members to extend through, and where the extending housing member contains within its interior a number of internal fluid passages for fluidly connecting the hydraulic pump to the hydraulic motor.Type: GrantFiled: March 23, 2001Date of Patent: August 6, 2002Assignee: Hydro-Thoma LimitedInventors: Christian Helmut Thoma, George Duncan McRae Arnold

Method and device for converting thermal energy and device with the thermal energy converting device
Patent number: 6427444Abstract: A thermal energy conversion device includes a heat converter composed of a medium containing portion (10) that does not substantially change in capacity and a variable portion (11) that is changeable in capacity, an operating portion composed of a piston (13), a pivot lever (15), and a driving lever (16), a first conversion and storage portion formed of a movement barrel (21), and a second conversion and storage portion formed of a power generator (30). When the ambient temperature changes, heating medium contained in the medium containing portion (10) changes in volume, and the capacity of the variable portion (11) is changed, thereby operating the piston (13). Motion of the piston (13) is stored in a mainspring disposed in the movement barrel (21) via the pivot lever (15) and the driving lever (16), and power is generated in the power generator (30).Type: GrantFiled: January 23, 2001Date of Patent: August 6, 2002Assignee: Seiko Epson CorporationInventor: Kenichi Miyazawa -
Patent number: 6427445Abstract: A variable nozzle turbocharger (12) creates engine boost. Boost is controlled by controlling the position of vanes within turbocharger. A processor develops a control signal (29) for controlling vane position. The processor develops a value for desired boost and processes that value with a value. corresponding to the amount of boost being created by the turbocharger to generate error data (48A) defining error between the amount of boost being created by the turbocharger and the desired boost, and the processor develops a component of the control signal by P-LI-D processing (62) of the error data. Other components of the control signal are a feed-forward value from a look-up table (34) and a value from an overspeed protection function (60).Type: GrantFiled: February 5, 2001Date of Patent: August 6, 2002Assignee: International Engine Intellectual Property Company, L.L.C.Inventors: Emad S. Isaac, John E. Bernhardt, Michael J. McNulty

Patent number: 6427446Abstract: An improved dual-stage, dual-mode turbine combustor capable of reducing nitric oxide (NOx) emissions is disclosed. This can-annular combustor utilizes multiple, single wall sheet metal combustor liners, generally annular in shape, and each liner having multiple hole film cooling means, which includes at least one pattern of small, closely spaced film cooling holes angled sharply in the downstream direction and various circumferential angles for improved liner cooling and improved fuel/air mixing within the liner, resulting in lower NOx emissions.Type: GrantFiled: September 19, 2000Date of Patent: August 6, 2002Assignee: Power Systems Mfg., LLCInventors: Robert J. Kraft, Vincent C. Martling, Brian R. Mack, Mark A. Minnich

Patent number: 6427447Abstract: An improved bulkhead for dual fuel industrial and aeroengine gas turbines, that may be formed by one or more bulkhead elements. Each element has a fuel-air channel, having an inlet for introducing air and an outlet for exiting a fuel-air mixture. Each element further includes at least one manifold for introducing a liquid or a gaseous fuel into the fuel-air channel. The channel and the manifold are formed by a plurality of etched layers of macrolaminate or platelet material. Each element may further include an air cooling channel for cooling the backside of the bulkhead. The bulkhead may be used in can and in annular combustors.Type: GrantFiled: February 6, 2001Date of Patent: August 6, 2002Assignee: United Technologies CorporationInventor: William Arthur Sowa

Patent number: 6427449Abstract: A compact, volatile organic compound removal system is presented. The system has a metal condensation plate and a cooling source in intimate thermal contact with the metal condensation plate. The metal condensation plate has a channel formed in the plate, an inlet in the condensation plate for introducing a gas carrying volatile organic compound vapors into the channel, a high surface area metallic structure, such as foamed metal or metallic fins, in intimate contact with the walls of the channel, an outlet in the condensation plate for removing the gas from the channel and a drain in the condensation plate for removing volatile organic compound condensates from the channel. The cooling source cools the channel walls and the high surface area metallic structure so that the volatile organic compound vapors condense on the high surface area metallic structure to be removed from the gas.Type: GrantFiled: December 15, 2000Date of Patent: August 6, 2002Assignee: Solid State Cooling SystemsInventors: Mark A. Logan, Lloyd F. Wright
