Abstract: A clutch mechanism includes a ferromagnetic anvil having an axial bore for axially receiving a pin; a cup axially aligned with the anvil for receiving a pin that is axially receiving by the bore of the anvil, wherein the anvil is longitudinally movable along its bore axis with respect to the cup; a spring for forcing the anvil toward a confining end of the cup; balls in the cup for engaging the pin when the anvil is forced toward the confining end of the cup, with the balls being disposed to apply radial pressure against the pin to firmly clutch the pin and thereby restrain the pin from longitudinal movement when the balls are forced toward the confining end of the cup; and a ferromagnetic shield disposed axially in relation to the anvil for diffusing magnetic flux applied axially to the anvil by a magnet external to the clutch mechanism so as to prevent less than a predetermined amount of the axially applied magnetic flux from overcoming the spring and forcing the anvil to move away from the confining end of the cup.  The clutch mechanism further includes a radially disposed pole piece for directing magnetic flux applied radially by a pole piece coupled to the magnet so that at least a predetermined amount of the radially applied magnetic flux is so concentrated axially in the anvil as to overcome the force of the spring and force the anvil to move away from the first end of the cup.

Title: Process and device for winding continuous webs of material, in particular paper or carton
Inventor: HEHNER REINHARD
IPC: B65H18/10
Filed: 1991-02-01
Granted: 2002-09-10
Abstract: In prior art processes for winding continuous webs of material (1), in particular paper or carton, on to spools, the material (1) pulled off a delivery roll against a braking force is divided, by cutting it along its length, into individual strips which are subsequently wound under tension onto individual rolls (19, 20). In order to be able to set different tensions for cutting and for winding at the winding stations (9, 10), the invention calls for the tension of the individual strips after cutting and before winding to be interrupted by passing the strips over a driven roller with which the strips lock fractionally. The tension is preferably interrupted by a free-running roll (22) which presses against the driven roller, thus holding the individual strips in place.

Date Jun. 24, 1993In performing micro-cleaning and micro-blasting, a dry micro-cleaning abrasive powder is sprayed having a very small grain size. This enables high cleaning speeds to be reconciled with exceptionally fine blasting in order to remove dirty stains and encrusted deposits from valuable, delicate, or fragile medium as is the case when having to blast off pollutants and pollution that become stuck to the surfaces of monuments and buildings. Jets of compressed air charged with fine abrasive particles having grain sizes of less than 200 micrometers can also be sprayed towards the surface. The jets are emitted from nozzles at high speeds so that they sweep the surface with at least ten jets, each of which has a cross section lying in the range of 400 micrometers to 4 millimeters, so that very low kinetic energy is imparted to the surface.
