  • Patent number: 12257206
    Abstract: A CPR machine (100) is configured to perform, on a patient's (182) chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A force sensing system (149) may sense a compression force, and the driving can be adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected.

  • Patent number: 10316809
    Abstract: A fuel injection system designed for an internal combustion engine includes at least one fuel injection nozzle which, by way of a cylindrical shell body, is inserted at least in regions into a bore of a cylinder head and which, by way of a nozzle tip, feeds fuel to a combustion chamber between the cylinder head and a reciprocating piston. The fuel injection nozzle is held in position on a housing section of the internal combustion engine with the interposition of a holding device and, for example, a fastening bolt. The holding device braces a first end region of the fuel injection nozzle against a bore stop within the bore in the cylinder head. To optimize this fuel injection system, the holding device has, outside the bore, a fixing bushing to which the shell body is fixed axially and radially by way of a radial insert element.

  • Patent number: 4878702
    Abstract: The closing of tubular casings containing foodstuffs by mounting a binder on a constriction of the casing involves the traditional problem of a high waste percentage due to the binders either damaging the casing material or sliding off the constriction. A method and a binder are proposed which makes it possible to obtain a very strong clamping of the binder without damaging the casing material, and, in connection with tight plastic casings, it is even possible to provide a "super tight" closure, by arranging the constriction with an oblong cross section between opposed straight clamping beams, which are forced together so as to produce a controlled deformation flowing of the casing material.

  • Patent number: 4370778
    Abstract: A novel sausage casing binder made of elements of plastic and a method by which the elements are mounted against the constricted portion of the casing so as to form a clamp ring thereabout, whereafter the elements are joined to stabilize the rigid and entirely closed annular shape of the clamp ring in secure engagement with the constricted portion. For binding the casing in the end which is going to be suspended by the smoking of the sausage a binding element is used which is provided with a suspension member forming an integral part thereof, whereby the use of special suspension members to be laid under the clamp is obviated and a very safe suspension is obtained.
