摘要:
A device for the removal of plastic injection moldings from the mold of an injection molding machine having movable and fixed die chucking plates includes a drive unit for moving an actuating element toward or away from the mold. The actuating element is connected to a spindle mounted in an engagement component. One end of the spindle is connected to a toothed disk. A tubular component is mated with the toothed disk so that the toothed disk is fixed with respect to rotation relative to the tubular disk and is axially movable therein. The tubular component is rotatable by the drive unit for effecting the axial displacement of the actuating element.

The invention concerns a drive arrangement of a crop conveying and/or processing mechanism of a harvesting machine with an internal combustion engine (25) that is arranged to drive the crop conveying and/or processing mechanism through power transmission elements in a first operating mode in a first direction at a first speed, and a reversible motor (86) that is arranged to drive the crop conveying and/or processing mechanism in a second operating mode at a second speed in a second direction that differs from the first direction. The drive arrangement is also able to be driven in one or both of third and fourth operating modes. In the third operating mode the reversible motor (86) drives the crop conveying and/or processing mechanism in the first direction at a third speed, that is lower than the first speed and in the fourth operating mode the drive of the crop conveying and/or processing mechanism is separated from the internal combustion engine (25) and the reversible motor (86) operates as a brake for the crop conveying and/or processing mechanism.

An axial piston machine, in particular an axial piston pump of a high-pressure cleaning device, includes a wobble drive having a wobble member rotatable about an axis of rotation, and a swash plate rotatably supported by the wobble member and extending at an inclination with respect to the axis of rotation. The swash plate interacts on one end face thereof with at least one piston. For simplification of the assembly of an axial piston machine, the wobble member is so configured as to have a conical portion flared in the direction of the swash plate and formed with a ball race for a ball bearing.

A dyeing aid composition containing 1 to 60% by weight of a surfactant selected from (a) C.sub.8-24 alkyl or alkenyl alcohol sulfate, C.sub.14-18 alkane sulfonate and C.sub.10-14 alkyl benzenesulfonate; (b) castor oil containing 20-50 mols ethylene oxide, alkoxylated C.sub.8-24 alkyl or alkenyl alcohols, and alkoxylated C.sub.8-12 alkylphenols; from about 1 to about 25% by weight of sulfated hydroxyalkyl alkylpolyalkylene glycol ether corresponding to formula I ##STR1## in which R is a C.sub.1-6 alkyl radical, R.sup.1 is a C.sub.6-8 alkyl radical, M is an alkali metal or, ammonium cation, n=2 or 3 and x is a number of about 2 to about 10; and from about 1 to about 30% by weight of C.sub.2-12 alkyl alcohol; with the proviso that the ratio by weight of surfactants (a) to surfactants (b) is from about 5:1 to about 1:5, the ratio by weight of surfactants (a) and (b) to sulfatized hydroxyalkyl alkylpolyalkylene glycol ether is from about 1:1 to about 4:1 and the ratio by weight of surfactants (a) and (b) and sulfatized hydroxyalkyl polyalkyene glycol ether to alkyl alcohol is from about 1:1 to about 5:1.
摘要:
A fastening element particularly adapted for use in conjunction with a mandrel for opening the expandable sleeve of the fastening element into secure relationship with a wall having a hole into which the fastening element is inserted. The sleeve is designed to provide a radial channel for enveloping the plate member adjacent the hole. The mandrel becomes a part of the fastener and offers good resistance to shear forces and also provides the means for removing the fastening element as well as fixing it to the object to be fastened.

An apparatus for deboning of poultry limbs or the like including at least one deboning unit which includes retaining means for the limbs, a stripping diaphragm and abutment means which by the bone is pushed out of the fillet, driving means moving the stripping diaphragm and the abutment relatively to each other with the stripping diaphragm being movably supported to limited extents in the diaphragm plane, the diaphragm including a movably supported driven diaphragm portion in order to open the diaphragm and to change the cross section of the diaphragm opening.
摘要:
The antenna has a main reflector (1), a subreflector (4a, 4b, 5a, 5b), and a feed radiator (2) which are all rotationally symmetric about a common axis (10). In a section in the direction of this axis of symmetry (10), the subreflector has the shape of two curves meeting in the axis of symmetry. Seen from the feed radiator, these curves are concave. Each of the two curves has at least one step (6a, 6b) for matching the feed radiator to the transmitter or receiver.
摘要:
A method for generating patterned structures on a monolith substrate in micro-mechanics to permit the production of at least two successive structurings with the depths required in micro-mechanics. At least two different, selectively removable etching masks which are etchable by different etching agents are applied in sequence to the substrate. A first structuring or patterning step is then employed after the last etching mask has been generated. A further etching step occurs after the removal of the last etching mask through the use of the etching masks then remaining on the substrate. The removal of additional etching masks and generating further structuring steps are repeated until the number of etching steps that have been carried out is the same as the number of etching masks that had been originally present on the monolith substrate.
摘要:
A slide is provided with a simplified support construction involving a reduced number of parts at reduced cost. Also, the appearance of the slide is improved by placing a substantial portion of the reduced support directly under the slide path. Each slide path may include only four vertical supports with the slide supported on those supports with only four cantilevered brackets. The brackets hold four girder segments extending end-to-end directly under the slide path.
