Abstract:
In an adjustment device for adjusting the phase position of a camshaft relative to a crankshaft of an internal combustion engine which includes a hydraulic system for supplying hydraulic fluid under pressure to the adjustment device for the controlled admission to, and release thereof from, operating chambers of the adjustment device under the control of a control device including a control valve, the operating chambers are in communication with one another via control valves to permit flow of hydraulic fluid from one set of operating chambers to another by the varying torques effective on the camshaft or by controlling fluid supply to the operating chambers from the hydraulic fluid supply system.
Abstract:
A guide mechanism for a track-guided toy vehicle which is equipped with an electric motor and can be operated on a road surface with a guide groove, engaging with a guide plate in the guide groove via a vertical axis of rotation on a chassis of the toy vehicle by means of a guide mechanism mounted on a chassis of the toy vehicle and being equipped with current collector elements for the electric motor, said collector elements cooperate with current rails in the road surface. A swing arm that is pivotable about a horizontal axis is arranged on the chassis of the toy vehicle which is placed upright on the road surface with the front wheels and rear wheels. The swing arm comprises the guide mechanism with the rotation axis, the guide plate and the current collector elements.
Abstract:
The invention relates to a device for combining two components. A first container accommodates the first component, which is liquid, and a second container accommodates a second, solid or liquid component under negative pressure. A body is provided with a first holder for the first container, in the region of the closure of the latter, and with a second holder for the second container, in the region of the closure of the latter. Displaceable means for piercing the closures are provided within the body. In the case of such a device, the invention provides that the body has two slides mounted in a displaceable manner in it, wherein each slide accommodates a cannula for piercing the respective closure, the cannulas are connected, in the region of their ends directed away from the closure, to an element which connects the cannulas in a liquid-tight manner, and actuating means are provided for moving the slides in the direction of the closures for the purpose of piercing the closures.
Abstract:
This invention relates to ammonium salts and stable storable ammonium salts and ammonium salt/mineral salt clathrate compounds (inclusion compounds, clusters) having acid dibasic anionic acid residues such as bicarbonate, to methods for producing them and to pharmaco-medical and chemical synthetic applications for said compounds. According to the invention, compounds for pharmaco-medical and chemical synthetic applications are produced which comprise the ammonium salt and ammonium salt/mineral salt clathrate compounds (inclusion compounds, clusters) having acid dibasic anionic acid residues of general formula I with R1, R2, R3 and R4=alkyl and substituted alkyl straight-chain or branched, optionally having an alcohol, ether, silyether, ester, amino or amide function, H or aryl-alkyl, with aryl being an aromatic or heteroaromatic ring having optionally additional substituents, such as alkyl having 1 to 4 C atoms, OH, NR*2 with R*2=O, alkyl with alkyl of between 1 and 4 C atoms or H, COOH, COOR, CN, NO2 and the cationic positive N+ is optionally part of an active agent, Y is a dibasic acid residue of an organic dicarboxylic acid or CO3−, corresponding to HY−=HCO3−, and x=0.5 to 30 represents the number of the mineral salt molecules for clathrate compound formation or 0. In pharmaco-medical applications applies the generalizable effectiveness principle according to which to ammonium salt/mineral salt cluster is used as vehicle and active agent for novel forms of application of nitrogen-containing active agent bases. In chemistry, these agents are used in the synthesis of active agents and valuable products, e.g. of cyclic carbonates.
Abstract:
A toy vehicle is operated as a track-guided vehicle and cooperates with a metallic current rail device of the track via one or more current consumers. A magnet is installed in the toy vehicle which is moved by an electric motor to optimize the traction between the track and the toy vehicle. This magnet is directed at the current rail device of the track. The magnet's magnetic force can be influenced as a function of driving operation states of the toy vehicle driven by the electric motor.
Abstract:
A current collecting device for a toy vehicle for use on an electrified track. The toy vehicle is for operation on a road surface, and is driven by an electric motor installed in a chassis and having a chassis frame that carries the electric motor, whereby the current collecting device has strip-like contact elements which cooperate with current rails of the road surface. The contact elements which are in contact with the current rails of the road surface are carried by a replaceable unit which is connected to the current collecting device.
Abstract:
A system is provided for controlling a fuel-metering device, for a diesel engine. First means generate a first signal for triggering a first actuating means (115) for establishing the start of pump delivery and the end of delivery. Second means generate a second signal for triggering a second actuating means (125) for establishing the delivery rate. In this case, a signal characterizing the start of pump delivery is taken into consideration by the second means.
Abstract:
A vehicle has at least one electric machine that can be operated as a generator, an electrical energy accumulator and a control unit for controlling the at least one electric machine and the electrical energy accumulator. The control unit operates so that in a recovery phase the vehicle can be decelerated by the generator load of the electric machine operated as a generator (2:a) and the resulting electrical energy (1:E) can be stored in the electrical energy accumulator. The control unit is configured so that the at least one electric machine operated as a generator in a recovery phase is operated by said control unit in a chronologically unlimited fashion with a predefinable overload (2′:a, 2″:a, 2′″:a).
Abstract:
A chassis is provided for a track-guided toy vehicle which is supported on a front axle and a rear axle and has a guide wedge that is movable about a first vertical pivot axle and cooperates with a groove in the raceway. The rear axle is driven by an electric motor, with the rear axle and the electric motor together forming an assembly. Steering capability of the vehicle, is optimized by arranging the assembly to be movable about a second vertical pivot axle. The assembly is operatively connected via a control unit to the chassis-mounted guide wedge.
