摘要:
A method for the control of a two-speed transmission with an electric machine in a vehicle that is operating in overdrive. The motor torque (M) produced by the electric machine is at first controlled independently of a driver's indication (F) in such manner that an approximately constant vehicle speed is reached.

An apparatus for treating headspace gas has a production water tank, a source of at least one of oxygen and ozone, a diffuser, and a reaction tank. The production water tank contains a headspace gas and a headspace gas outlet. At least a portion of the headspace gas is a sulfide gas. The diffuser diffuses a mixture of the at least one of oxygen and ozone and headspace gas from the production water tank via the headspace gas outlet into a liquid solvent. The at least one of oxygen and ozone oxidizes at least a portion of the sulfide gas as they pass through the diffuser. The reaction tank for receives the liquid solvent.
摘要:
The invention concerns a device for actuating a diaphragm spring clutch (20) for vehicles by means of a pneumatic, hydraulic or electric actuator (24), comprising a controller connected upstream of the actuator (24), whose output control variable actuates the actuator (24). To compensate for the strong nonlinearity of the releasing force over the releasing stroke that is typical of diaphragm springs, a controller is used, whose characteristic curve is plotted in such a way that this nonlinear curve of the releasing force is at least approximately compensated via a correspondingly coordinated actuation of the actuator (24), so that it remains essentially identical over the releasing stroke.

A carrier of gearset (RS4) couples the input shaft forming shaft (1). A carrier of gearset (RS3) couples the output shaft forming shaft (2). Sun gears of gearsets (RS1, RS4) couple forming shaft (3). Ring gears of gearsets (RS1, RS2) respectively form shafts (4, 8). A carrier and sun gear respectively of gearsets (RS2, RS3) couple forming shaft (5). A carrier and ring gear respectively of gearsets (RS1, RS3) couple forming shaft (6). Sun and ring gears respectively of gearsets (RS2, RS4) couple forming shaft (7). In the power flow, elements (A, B) are respectively between (3, 4) and a housing, element (C) between (1, 5), element (D) between either (2, 8) or (6, 8), shifting element (E) between two of (5, 7, 8).

摘要:
A method of selecting a neutral position of an automatic or automated transmission and a parking gear to immobilize a motor vehicle. The neutral position and parking device can be set or activated, depending on a gear selected by the driver with a selector device and depending on other vehicle operating parameters. Only when the motor vehicle is at least substantially stationary, an ignition circuit acting on the drive motor vehicle is electrically interrupted and a “Neutral” (N) gear is selected by a selector device occur simultaneously, can an N-holding phase, in which the transmission is in a friction-free neutral position, be activated by a separate control device provided in addition to the selector device, as long as an energy management system of the motor vehicle allows activation of the N-holding phase.
摘要:
An underwater writing tablet/instrument apparatus comprising a writing tablet having a perimeter edge. A resilient protective border is secured to the perimeter edge of the writing tablet for protecting perimeter edge. A resilient elongate member has opposed first and second ends with the first end attached to the protective border while the second end has a writing instrument receiving component for retaining a desired writing instrument. The elongate member has an normal, unexpanded state and an expanded state in which the coil member is resiliently expanded to facilitate a diver writing on the writing tablet with the writing instrument.
摘要:
An apparatus and method for applying a blasting media, comprised of at least first and second separate types of particles, to a surface to be treated. Each type of particle may comprise a core coated with a desired component, e.g. abrasive, absorptive, polishing, etc., and the components are selected so as to minimize the density variation of different types of media being combined with one another for the surface treatment. The different types of particles are mixed with one another prior to application to a surface to be treated. The mixing may occur in a mixing tank prior to use, in the media supply conduit prior to the nozzle, at the discharge outlet of the nozzle, or just prior to contacting the surface to be treated. By employing different types of particles, cleaning and reuse of the media is facilitated while also minimizing the amount of media consumed per unit area of wall to be treated. In addition, an operator is able to custom blend the media, during use at a jobsite, to maximize surface treatment, per pound of media, and minimize the generation of disposable waste.
摘要:
A mechanism for actuating a transmission having shifting elements. A self-holding valve device is movable into a first position, by a pilot pressure, against a force directed to a second position and held by a pressure holding signal in the first position. Transmission of a pressure signal, to a switching valve, is blocked by the self-holding valve device in the first position but, in the second position, is applied to the switching valve. When the driver sets the switching valve to a first shift position, the pressure signal can be applied to valve devices of at least two of the shifting elements that produce an actuating pressure and, in a second shift position of the switching valve, the onward transmission of the pressure signal, to the valve devices of the shifting elements that produce an actuating pressure, is blocked in the area of the switching valve.
摘要:
A gearshifting unit for a vehicle transmission (6) comprising a main transmission part (10) manually shifted by the vehicle driver using a gearshift lever (16) and one range change group transmission (14) shifted by valves (44, 46). The gearshifts are manually preselectable by the vehicle driver using a gearshift lever (16), the same as a power assistance device (74) for shifting the gear steps in the main transmission part (10) and one electronic control device (20) which actuates the valves (44, 46). In a method for reducing the power assistance, a neutral position is detected in the manually shifting main transmission part (10) and once the neutral position is determined, the gearshift begins in the range change group transmission part (14) and the power assistance is engaged with a delay.
