Hard metal insert body as a tool or for insertion at correspondingly loaded places of tools, especially those exposed to frictional and impact loading, for example for machining stone, concrete, ceramics or like materials and also for machine wear parts, is constructed for resistance, with optimum life, to different simultaneous loadings, especially frictional and impact loadings, such that it con...

The invention relates to a process for the flotation of fermentation sediment, in which a mixture of gas bubbles and fermentation sediments is introduced into an upper space of a flotation cell through which liquid flows in a turbulent manner, which then flows vertically through a space below, the flow being divided into individual vertical non-intermixing flow elements in such a manner that the r...

A forage harvester shear bar having a first surface across which crop material is fed for cutting by the harvester cutterhead. A cutting surface perpendicular to the first surface forms a cutting edge therewith. The shear bar is arched upwardly by clamping against an arched support to provide enhanced rigidity and strength. The cutting surface is formed with a concavity therein, prior to being wor...

The invention relates to an X-ray mammography apparatus having an arrangement for the taking of fluoroscopic images by means of an X-ray film (16) to which an intensifier film (15) is applied. In this case, it is desired to increase the attainable image contrast without impairing the effectiveness of an automatic illumination control (12). To this end, the invention proposes the use of an X-ray fi...

The invention relates to an X-ray apparatus which allows for the determination of the elastically scattered X-rays and the evaluation of the information contained therein. Because the scattered radiation exhibits a pronounced maximum value as a function of the scatter angle and because the scatter angle at which this maximum value occurs depends on the material in which the scattered radiation is ...

The invention relates to novel water soluble 3,5-diacetamido-2,4,6-triiodobenzoic acid derivatives, the method for making the same and their use as X-ray contrast agents for vasography, urography, myelography, artrography, fistulography and salpingography.

An electromagnetic valve assembly is shown having an armature and armature-actuated valve member the mass of which is substantially less than the armature and which is not fixedly connected to the armature; upon electrical energization the armature first overcomes a restraining force and then travels a major part of its stroke before actuating the valve member, at a relatively high speed, thereby ...

An apparatus for continuously transmitting electrical energy or a fluid stream between a fixed terminal and a continuously rotating terminal through a flexible continuous transmission element, such as an electric cable or a tube, comprises three rotors having a common axis of rotation, namely an outer rotor, an intermediate rotor and an inner rotor. The outer and intermediate rotors are rotated at...

A system for controlling an electro-magnetic clutch of an internal combustion engine mounted on a vehicle, which has a drive member secured to a crankshaft of the internal combustion engine, magnetizing coil provided in the drive member, a driven member adjacent to the drive member, and a transmission secured to the driven member having multi-stage change gears. A car speed sensor is provided for ...

A tire whose inner wall is provided, below the crown of the tire and at least from one shoulder to the other of the tread, with a lining containing at least one means for sealing puncture holes is improved due to the fact that the lining comprises at least one layer of a vulcanizable sealing mixture separated by a vulcanized elastomeric partition from at least one layer of a vulcanizing mixture ca...

In a bottle inspection machine a cylindrical hollow shaft is driven rotationally about a vertical axis. Another shaft is splined in the tubular shaft for rotation therewith. Another rotor is mounted coaxially to the inner shaft and the two rotors constitute a means for transporting bottles in a circular path. A light source is mounted on the radially outer side of the circular path and projects be...

An apparatus for the processing and scrubbing of contaminated gases i.e., gases entrained with particulate matter, is presented. The apparatus comprises a primary dust removal unit which receives a descending gas pipeline originating from a generator or source of contaminated gases. This primary dust removal unit acts to precipitate the larger solid particles from the contaminated gas via gravity ...

Date Dec. 6, 1984.A method and arrangement for transmitting data in a data loop comprising at least two stations and at least one of which is an overriding master station in which a transmission frame for the data to be transmitted is generated for transmission ...

The invention relates to an arrangement for damping shifting movements in a mechanical, synchronized multispeed transmission. Where such shifting movements are performed with the aid of a servo-mechanism, for exmaple a pneumatic piston cylinder unit, there is the risk that the gear teeth will be damaged when brought into engagement with each other. In the arrangement according to the invention, a ...

Information from a main data processor is transferred to an auxiliary data processor of the system and is stored in a control file which may be addressed by either a firmware word from a control store or by use of the function code received in an instruction from the main processor. Information in such control file is used for the purpose of addressing main memory. The address for main memory may ...

A system for diagnosing an internal combustion engine.
