摘要:
A saw chain for motor-driven chain saws includes a cutting link which has three mutually adjacent supporting surfaces defining a U-shaped cutout for accommodating a hard metal insert in the form of a cutting plate therein. The support of the insert is provided at only subportions of these supporting surfaces and the remaining subportions provided an adequate spacing so that a solder gap is formed. The hard metal insert placed in this cutout has an adequate service time and does not require special equipment to hold the same during automatic soldering thereof into the cutting link.

The invention is directed to a saw chain for a motor-driven chain saw which includes cutting links, side connecting links, driving links and safety links. Each safety link has an upper edge defining a wave-like contour that prevents chips from accumulating during the cutting action. The cutting links and safety links of the saw chain are arranged with respect to each other so that overlap is avoided between the tail end of the rearward projection of the safety link and the forward projection of the depth limiter of the cutting tooth. This affords the advantage that cutting chips do not become jammed therebetween.
摘要:
A saw chain has pivotally interconnected chain links which includes cutting links and safety links and these links are effective as working links. The cutting links are each provided with a cutting tooth for cutting into wood and the safety links are each provided with a projection which limits the depth of the cut of the cutting tooth which follows the safety link. The pivot axes of the chain links lie in an action plane above the guide bar in the stretched portion of the saw chain when the latter is subjected to the pulling force exerted by the drive of the chain saw. The cutting links are pivotable with respect to this plane. In addition, the safety links can also be pivotable in this manner. When the cutting links are in their pivoted-out position under this pulling force, no clearance angle is available at the roof of the cutting tooth so that the cutting edge has no cutting effect. For this reason, there is no kickback when the saw chain is placed against the wood. When an advancing thrust is applied to the chain saw, the cutting links in the stretched running portion of the chain are pivoted into their pivoted back position or working position by means of reaction forces; whereas, in the direction-reversal region of the guide bar, the cutting links are retained in their pivoted-out position by means of the support imparted to the drive links by the nose sprocket of the guide bar. In this way, the danger of kickback remains low.

In a method for separating magnetizable particles from a suspension, the suspension is passed through a cylinder-symmetrical separator wherein the substance streams are separated by at least one tubular separation screen. The separator separates the substance stream into a concentrate as well as a so-called tailing and the control of the separation rate of the concentrate and tailing is carried out solely by controlling the flow rate. To this end, at least one separation screen (11, 21) is displaceable in the separator (10, 20), so that a variable gap (15, 25) is formed.

The invention relates to a drive unit (10) for a windscreen wiper device in a vehicle with a multiple-section housing (11) with a drive motor (1), more particularly connected to the housing (11), which is at least indirectly controllable by means of conductor leads (17), more particularly in the form of punched components, whereby the conductor leads (17) end in a plug connection (14) of the housing (11) via which the drive motor (1) is externally electrically powered, whereby the housing (11), at least in the housing section (12; 12a to 12c) accommodating the conductor leads (17) is designed as an injection moulded component, in which the conductor leads (17) are at least partially overmoulded with the material of the housing section (12; 12a to 12c). In accordance with the invention it is envisaged that the conductor rods (17) are also arranged in a sealed manner on the inside of the housing (19) so that the penetration of moisture into at least the section of the inside of the housing (19) overmoulded by the material of the housing section (12, 12a to 12c) is prevented.

The present invention relates to a process for separating at least one first material from a mixture comprising this at least one first material and at least one second material, which comprises at least the following steps: (A) contacting of the mixture comprising at least one first material and at least one second material with at least one surface-active substance, if appropriate in the presence of at least one dispersion medium, with the surface-active substance binding to the at least one first material, (B) if appropriate, addition of at least one dispersion medium to the mixture obtained in step (A) in order to obtain a dispersion, (C) treatment of the dispersion from step (A) or (B) with at least one hydrophobic magnetic particle so that the at least one first material to which the at least one surface-active substance is bound and the at least one magnetic particle agglomerate, (D) separation of the agglomerate from step (C) from the mixture by application of a magnetic field in order to obtain the agglomerate and a mixture M1 depleted in agglomerate, and repetition of the steps (A) to (D).
摘要:
In devices for producing strong current high power impulses, the electronic components, which include passive components including capacitors and/or switch elements, including semi-conductor switches, diodes or similar elements, need to be protected against overcurrents in the event of an error function. Generally, serial resistance and serial inductance are used. The serial resistance and the serial inductance are combined together in such a manner that a coil having necessary resistance and inductance values is produced.
