摘要:
A dispensing device, a storage device and a method are proposed for dispensing a formulation as a spray. The formulation is dispensed by means of a gas stream. To improve the dispensing effect, pressure pulses are generated in the gas stream and/or the direction of gas flow alternates. The formulation is dispensed through a duct. The duct is connected to a storage chamber containing the formulation via a sharp edge or transition portion.

The present invention relates to a 1,4,2-diazaphospholidine of the formula (1) wherein R1, R2 represent, independently of one another, saturated or mono- or polyunsaturated C1-C20-alkyl, -alkenyl, -alkynyl or C5-C40-aryl groups optionally substituted or interrupted by at least one heteroatom selected from the group consisting of N, O, S, and halogen, and X represents identical or different substituents selected from the group consisting of O, S, and N—R2.
摘要:
A connecting device of a vehicle drive-train, located outside a variable-speed transmission, for rotationally coupling a shaft to a drive-train element. A sliding sleeve is rotationally fixed on the shaft but slides axially between first and second positions. In the first position, the shaft is rotationally disengaged from the drive-train element and, in the second position, they are rotationally coupled. An actuator displaces the sliding sleeve between the first and second positions, with a shift groove along a peripheral contour of the sliding sleeve and engagement members for engaging in the groove. The sliding sleeve can rotate and move axially relative to the engagement members and the groove is shaped as a curved guiding such that, when the engagement members engage in the groove and the sliding sleeve rotates relative to the engagement member, the sliding sleeve moves axially between the first and second positions by virtue of the groove.
摘要:
A valve train of a combustion piston engine having an actuating device which comprises a phase shift gearbox with two inputs and an output for phase adjustment of a camshaft. The first input is connected with a crankshaft, the second input is connected with a controllable braking device and the output is rotationally fixed with the camshaft. The brake is an electromagnetically controlled friction brake which comprises an electromagnet and magnetic coil. A brake rotor is connected with the second input and can be biased, by the magnetic field of the electromagnet, against a friction surface. A permanent magnet is positioned axially adjacent the brake rotor such that, by its magnetic field, the brake rotor can be pressed against a fixed friction surface for the adjustment of a basic brake torque with the respective basic pressing force.
摘要:
The invention relates to an unsaturated polyester resin containing a polyester or a polyester mixture, produced from at least one unsaturated dicarboxylic acid and at least one diol; and at least one silazane which is accessible for copolymerization with a C═C double bond of the dicarboxylic acid. The invention also relates to an unsaturated polyester resin moulding material which can be obtained or is obtained by cross-linking an unsaturated polyester resin as defined above. Said moulding material can optionally contain reinforcing materials. Said unsaturated polyester resin can be produced using the following steps: (a) a polyester from at least one diol and at least one unsaturated dicarboxylic acid is provided; (b) at least one silazane which is accessible for copolymerization which a C═C double bond of the dicarboxylic acid is provided; (c) the components are mixed according to (a) and (b). The unsaturated polyester resin moulding material can be produced from the above-mentioned polyester resin by hardening thereof by means of a radical initiator.

The present invention relates to a process for the preparation of 3-aroyl-5-aminobenzofuran derivatives useful as antiarrhythmic drugs which avoids the use of nitro intermediates.
摘要:
A driving device (10) for driving a unit (11) is specified, with a drive shaft (16) on which a plurality of rolling bearings (19 to 21) serving to drive respective functional elements of the unit (11) are arranged next to one another. The rolling bearings (19 to 21) are designed as unencapsulated needle bearings (22 to 24) and are arranged directly next to one another on the drive shaft (16) in such a manner that the inner ring (25, 26) of a needle bearing (22, 23) is in touching contact by means of its end surface (43, 44), which is located on an axial side, with the facing, axial end surface (46, 47) of the outer sleeve (32, 33) of the needle bearing (23, 24) following next axially.
摘要:
Apparatus comprises: a housing, the housing having an aperture; a shaft; and plural blood sample collection members supported on the shaft. The apparatus is constructed such that different ones of the plural blood sample collection members are able to be presented at the aperture in turn. Each of the blood sample collection members may be independently rotatable about the shaft.
摘要:
A metering device is used for the metered administration of a flowable preparation together with a flowable carrier medium. A storage container for the preparation has at least one access opening. A metering plunger body can be moved in a sealed manner in the storage container between a starting position and at least one metering position. The metering plunger body is hollow. A metering sleeve has on a bottom side an eccentric metering sleeve opening. An inner plunger body has on the bottom side an eccentrically arranged plunger body opening. In a through relative rotation position of the metering sleeve relative to the inner plunger body a passage is provided between the inside of the storage container and the inside of the inner plunger body. In a closed relative rotational position this passage is closed. This results in a user-friendly and compact metering device.
