Abstract: An all-steel clutch having at least one eccentric pack of spring plates which holds the clutch halves axially at a distance in the unloaded condition and is so inclined by an acute angle to the axial normal plane that a slight axial displacement of the clutch halves in relation to one another produces a comparatively large angular offsetting, thereby enabling angular displacements caused by loading to be compensated.

Abstract: The invention is directed to an internal combustion engine for a portable handheld work apparatus with an intake pipe or induction elbow being attached to the cylinder. The engine can be a two-stroke engine having an inlet opening in the cylinder for the combustion mixture. A cylinder flange is provided at the inlet opening for connecting the induction elbow for conducting the combustion mixture. The induction elbow is made of rubber-elastic material and fits over the cylinder flange in a form-tight manner and is fixed thereto. The connecting end of the induction elbow is provided with an inner annular shoulder which engages an outer annular slot of the cylinder flange which is adapted with respect to volume and is reliably held by a clamp ring having a fixed diameter. The rubber-elastic material of the connecting end is compressed in the annular slot by the clamp ring thereby seating the induction elbow on the cylinder flange in such a manner that it cannot become disconnected.

Abstract: The invention relates to a portable handheld tool such as a motor chain saw, cutoff machine or the like having a motor arranged in a housing. The motor drives a work tool via a drive pinion. The portable, handheld tool is provided with a handle arrangement for holding and guiding the tool with the handle arangement being decoupled from the motor system by antivibration elements. Soft antivibration elements are required to obtain high isolation; whereas, the antivibration elements have to be as stiff as possible in order to reliably guide and hold the handheld tool. The antivibration elements holding the handle arrangement on the side of the drive pinion are arranged to lie approximately in a common plane. This arrangement makes it possible to use softer antivibration elements without the required stiffness for guiding and holding becoming too low.

Abstract: The invention relates air-cooled combustion engine powered handheld tool. A fan screen has radial struts and tranverse walls which together define windows. The effective intake suction area of the fan is less than the area of the screen. Wood chips and the like are kept out by the size of the windows and the reduced air flow velocity through the screen.

Abstract: The invention is directed to the handle of a portable handheld tool such as a motor-driven chain saw. The handle is configured as a plastic body homogeneous with its bearing portions. The handle is for the most part hollow and can be configured as a unit to include further functional portions such as recesses for vibration attenuators, air guide portions and the like. The plastic handle is especially suited for portable handheld motor-driven chain saws.

Abstract: The invention relates to internal combustion engines and especially to two-stroke engines for portable handheld work tools such as motor-driven chain saws or the like. Material made of light metal alloys is used in two-stroke engines for portable handheld tools in order to save weight. Thus, the crankshaft bearing is made of steel while the bearing covers holding the bearing are made of a magnesium alloy. Heating causes the bearing cover to expand by an amount greater than the crankshaft bearing whereby the press fit of the crankshaft bearing can become endangered and, in an extreme case, a clearance can develop between the crankshaft bearing and the bearing cover. According to the invention, the press fit between the crankshaft bearing and the bearing cover is maintained by placing a plastic annular segment therebetween having a thermal expansion coefficient so selected that it compensates for the different thermal expansions of the bearing cover and the bearing.

Abstract: The invention relates to an overload release clutch having: a hub 2 which is disposed on a shaft 1 and has two coupling halves 3,6 which are coupled with provision for axial disengagement in relation to one another by means of a positive connection 4,5 one clutch half 3 being disposed rotatably and axially secured on the hub 2 and the other clutch half 6 being disposed non-rotatably and axially displaceable thereon, the other clutch half 6 being urged towards the first-mentioned clutch half 3 by a spring arrangement having an adjustable axial force and a snap-over characteristic characterized in that the spring arrangement has a concentric resilient ring 8 which is so borne on the hub 2 by means of radially directed rigid bearing elements 10,21 inclined at an angle to the axial normal plane in the direction of the ring 8, that, when acted upon with an axial force directed towards the direction of inclination of the supporting elements 10, the ring 8 can be radially expanded.

Abstract: The invention is directed to an air-intake arrangement for a two-stroke engine for use in hand-guided, engine-driven apparatus such as motor-driven chain saws. The air-intake arrangement includes an air filter and a baffle wall for guiding fuel particles that are buffeted back out of the air induction channel by the engine. The baffle wall has a curvature to define a deflector to redirect the fuel particles in a largely gaseous state towards the carburetor. The arrangement provides an optimum air-fuel mixture which is not overrich and a trouble-free operation of the engine.

Abstract: The invention relates to a torque-limiting clutch. An engagement lock (2, 8, 9, 11, 12) and a friction clutch (6, 20-26) disengageable counter to the force of an axially acting spring are arranged in series in the force transmission path between the drive side (1) and the power take-off side (26) of the clutch. The engagement lock (2, 8, 9, 11, 12) is stressed by a second spring which, when the engagement lock has been disengaged, acts on a first portion of the adjustment travel only. Assigned to the locking device (9) of the engagement lock (2, 8, 9, 11, 12) is an ascending curve, the steepness of which is greater over the first portion of the adjustment travel than over the portion adjoining the latter. In this clutch, the limiting torque is determined solely by the second spring.

Abstract: Apparatus for the layer-wise imaging of an object by means of a large number of radiation sources which are situated in a radiation source plane and whose radiation beams intersect one another so that the approximately equally large radiation beam cross-sections which are situated in one irradiation plane almost completely cover one another. A record carrier is arranged on the other side of the object in order to record perspective images produced by the radiation beams. A imaging matrix which comprises imaging elements for the superposition of the perspective images on an image display device is disposed behind the record carrier. Displacement means are provided in order to realize a relative movement between the irradiation plane and the object or an object table carrying the object.

Abstract: In a circular loom a reed and at least one shuttle are arranged between an upper and a lower running ring of a machine frame. A rotor driving the shuttle, a harness arranged in a concentric circle about the rotor for shedding the warp threads, and tensioning means for the warp threads also are provided. A wave-like extending groove is provided in the outer side of the rotor and catch elements engage therein. The catch elements are connected with flexible bands or cords carrying thread guiding organs arranged at a distance from one another. The bands or cords are deflected at least about upper deflection pulleys, the thread guiding organs coming to lie on opposite sides of the deflection pulley and the upper deflection pulley being at the height of the upper running ring.

Abstract: The invention relates to a method of and a device for forming images of a layer of a three-dimensional object. In order to obtain high-quality images, the object is irradiated by means of a necessarily large number of radiation sources which are arranged in different mutually parallel planes or which are arranged to be displaceable (for example, rotatable) with respect to the object. Alternatively, the object with the record carrier (X-ray film) may be arranged to be displaceable with respect to the radiation sources. In the decoding step (superposition and summing of the shadow images) use is made of the two dimensional distribution of all radiation sources used during coding (irradiation) of the object.

Abstract: A centrifugal clutch for power saws. The clutch includes a rotating driven centrifugal weight carrier, and a clutch drum which is concentric to the axis of rotation of the carrier. At least one centrifugal weight engages the clutch drum at predetermined speed of the carrier. The centrifugal weight is coupled with at least one return weight in such a manner that the return weight opposes the pressing force of the centrifugal weight when the speed increases over a certain level.

Abstract: A safety device on a power saw which is provided with two handles, especially for a power chain saw. The saw has a brake which engages a drive member of the cutting tool of the saw under the effect of a force retainer; the brake is held in the ineffective or inoperative position by a stop which is actuated by operating elements associated with the two handles. The stop is locked in its locking position and is releasable by means of an adjustment device which is driven by an energy source supplied by the engine of the saw, and is controlled by a control device which is connected to the operating elements which are embodied as key or contact switches.

Abstract: In fan beam X-ray scanners operating with a large number of detectors, errors at and near the center of rotation are caused by the fact that the radiation absorption in said area is substantially always measured by the same detectors and that the sensitivity of all detectors is not exactly the same. The invention provides an improvement in that the measurement is carried out with a larger number of detectors than is necessary for the measurement of the scanning field and that the detectors pivot during the measurement. As a result, the absorption in the center of rotation is measured by different detectors so that, for a sufficient number of detectors the different sensitivities, errors are averaged and thus reduced or cancelled.
