摘要:
A liquid herbicidal composition containing pinoxaden and an adjuvant, where the adjuvant is a built-in adjuvant consisting of a trisester of phosphoric acid with aliphatic or aromatic alcohols and/or a bis-ester of alkyl phosphonic acids with aliphatic or aromatic alcohols.

An electromagnetic hysteresis brake is provided with a two-part pole ring with an inner and an outer pole ring part (5, 6) and a field coil (10) and further provided with a rotating ring (3) made of a permanent-magnetic material, the ring (3) projects into an annular air gap (11) of the pole ring which is formed between the inner and the outer pole ring parts (5, 6), at least one of the air gaps (12) of the brake is adjustable.
摘要:
A multifunctional RNA having self-processing activity, the preparation thereof and the use thereof Host cells can be transformed so that they express ribozyme RNA and antisense RNA which are connected with each other via a spacer. The RNA molecules can, for example, be complementary to a certain viral RNA. Plants which have been transformed with genes coding for RNA of this type show a significantly improved resistance to viruses.

Concentrated, stable suspension of herbicidally active 1,3,5-triazines in a solution of pyridate in organic solvents or mixtures thereof, in which at 0.degree. C. pyridate is at least 10% by weight soluble and the 1,3,5-triazines are at most 1% by weight soluble, together with emulsifiers, as well as its use and a method for controlling weeds.
摘要:
Virus genes, for example coat protein genes, which bring about a reduction in the signs of infection by the corresponding virus or bring about virus resistance can be combined with herbicide-resistance genes for the transformation of plants.A combination of this type facilitates the selection of the transgenic plants. In addition, in practical field cultivation, the vitality of the plants is increased by the virus tolerance, and an improved plant protection is possible owing to the herbicide-resistance gene.
摘要:
A process for producing sintered parts with high wear resistance and good dynamic strength properties from formed bodies, which have been pressed as green parts from a completely-alloyed air-hardened heat-treatment steel powder with a carbon content of at least 0.3% added in the form of graphite. The process includes sintering the parts under protective gas at a sintering temperature of at least 1000.degree. C. and subsequent cooling. The sintered parts are cooled immediately after sintering from the sintering temperature to a first holding temperature in the range of Ar.sub.3 to a maximum of 150.degree. C. above Ar.sub.3 and are held for a first holding period of 5 to 25 minutes at this temperature (austenitizing phase). Immediately after this, the sintered parts are cooled in accelerated fashion to a second holding temperature by convective gas cooling and are held at this temperature for a second holding period. The second holding temperature lies in a temperature range in which a bainitic structure forms and is of such a length that a bainitic structure portion of at least 50% is established. The sintered parts are then cooled to room temperature.
摘要:
A stack of individual sheets of film is enclosed by lightproof plastic packaging. An opaque sheet is disposed at the bottom of the stack, and the side of the opaque sheet confronting the packaging is provided with a bar code containing information about the film. The packaging is removed in a lighttight area of a processing unit for the film and the bar code is read. The opaque sheet prevents the radiation used to read the bar code from reaching the film. The information retrieved from the bar code is employed to control processing of the film.
摘要:
The invention provides a screw nut comprising a central inner thread and a radially extending slit, the width thereof essentially corresponding to the diameter of the central inner thread. Thus, a threaded bolt or a threaded stud can be radially inserted into said screw nut body. In order to avoid that the screw nut is displaced away from the threaded bolt or stud during tightening of the screw nut, the central inner thread comprises a plurality of thread turns provided with axially extending recesses directed towards the end surface of the screw nut which is under load when the screw nut is tightened on the threaded bolt or stud.
摘要:
The invention refers to a tool or workpiece storing magazine incorporating a tool- or workpiece-change apparatus adapted to remove a tool or a workpiece from the magazine and to transport the it into a machining apparatus, and to remove a tool or workpiece from the machining apparatus and to transport it back to the storing magazine, respectively. The system comprises a plurality of essentially disc-shaped tool or workpiece supporting members rotatably and coaxially arranged with reference to a first axis of rotation which receive and support a plurality of tools or workpieces along the periphery thereof. A transport arm is pivotally mounted on a second axis of rotation and longitudinally displaceable along said second axis located in a certain distance from said first axis of rotation. The transport arm is adjustable with reference to its length and includes a gripping member mounted on its free end. The transport arm further includes a turning knuckle, the axis thereof extending in an angle of 45.degree. with reference to the length adjustment direction of the transport arm, and a transport arm element, one end thereof being connected to said turning knuckle and the other end thereof bearing said gripping means, whereby the transport arm element means is generally L- or arc-shaped.
