摘要:
The invention relates to a drive unit for a safety belt tensioner which has a drive which can be triggered on the response of an acceleration sensor and which can be rotationally fixedly coupled to the belt winding reel. The drive is located in a drive chamber which is formed by two plates, which extend parallel to one another and which are provided with a coating material, and which has a drive band of which at least one end is fastened to a drive shaft.

In an electromagnetically actuated dual clutch-brake combination (8), a drive input shaft (2) can be optionally engaged in drive connection with a first drive output shaft (4) or with a second drive output shaft (6). The second drive output shaft (6) is associated with an electromagnetic brake (52), which is provided in order to immobilize the second drive output shaft (6), whereas the first drive output shaft (4) can still be connected to the drive input shaft (2) by an electromagnetic clutch (28, 32). The electromagnetic dual clutch-brake combination is suitable for controlling a variable longitudinal differential lock and a shiftable range gear system of an all-wheel distributor gearbox, with only a single electric motor.
摘要:
An excitation control circuit for a brushless synchronous welding generator, in which the stator-mounted excitation winding is fed from a separate voltage source via two parallel-connected power transistors with independently adjustable base circuits, one transistor controlling the excitation current in the idling mode, the other in the welding mode. A change-over switch, responding to an electromagnet in the welding current circuit, alternatingly energizes one transistor, while blocking the other.

A filter material forming a filter layer consisting substantially exclusively of celluloses and cellulose derivatives. In addition to cellulose acetate fibers, the filter layer contains, in the form of additives, microcrystalline cellulose and microfine cellulose, or else microcrystalline cellulose only. The amount of microcrystalline cellulose can be as high as 70% of the weight of the filter layer and that of microfine cellulose up to 50% of the weight of the filter layer. Cellulose acetate fibers can be excluded if in their place, microcrystalline cellulose having particle sizes less than 10 .mu.m. are used. The manufacturing method provides for cellulose acetate fibers to be first mixed in a wet state with microfine cellulose and microcrystalline cellulose, after which differently prepared celluloses are admixed. The mash formed by mixing is formed into a fleece by means of a known felting method, and the fleece is subsequently dried. With layers of the filter material, filtration efficiencies up to and including a sterilizing range are achieved, which renders them comparable to known kieselguhr layers.
摘要:
A drive for a belt tensioner for safety belts has a drive chamber formed between two plates. A drive band whose two ends are fastened to a drive shaft such that the drive band forms a loop which can be exposed to expanding gas discharged from a gas outlet such that the drive band winds off and drives the drive shaft. The drive band is fixed to the plates by a fixing apparatus at a position disposed between its ends.

In a parallel setting device for a print head carriage guide relative to a print medium support (6) in printers, in particular in matrix printers, the print head carriage guide includes a parallel disposable and position adjustable carriage guide axle (5) relative to the print medium support (1) and disposed rearwards relative to the print medium support at the printer frame 1 and a front carriage guide axle (4) adjustable to a minimum distance and disposed opposite to the print medium support (6). The rear and the front carriage guide axle (4,5) in each case are supported in the side plate (2,3) of the printer frame (1). The print medium support (6) is disposed at a level different to that of the front carriage guide axle (4). In order to find a simple and more precise operating solution, which is based on measurable part steps, it is recommended, that the rear carriage guide axle (5) is supported in the side plates (2,3) with cams rings (13) and a parallel positioning between the print medium support (6) and the print head carriage guide is adjustable by one-sided lifting and lowering of the rear carriage guide axle (5).
