  • Patent number: 5241934
    Abstract: A liquid-cooled internal combustion engine having a piston-controlled exhaust, particularly a two-stroke cycle internal combustion engine, is provided with a generator or a magneto-generator unit and with a lubricating oil pump. The cylinder head is provided with a cap, which defines a space for cooling liquid and extends over the cylinder approximately as far as to the exhaust port and at its end that is adjacent to the crankshaft has a sealing surface. In order to minimize the transmission of solid-borne sound and the radiation of sound, the cap and the cover for the oil pump are secured by means of collar screws, which have been tightened against a stop, and a washer provided with a vulcanization-bonded rubber layer is disposed between the head of each of said screws and the cap or the cover.

  • Patent number: 5164550
    Abstract: An intake muffler, which is particularly intended for use in two-stroke-cycle internal combustion engines, comprises a stiff housing, in which a partition defines two chambers. An inlet tube extends into the larger first chambr. At least two communicating tubes extend through the partiton. The second chamber communicates with a tubular outlet port. In order to ensure an effective damping of sound even in conjunction with a high engine power, the inlet tube consists of a diffuser, which is divided into two or more passages, and the tubes through which the two chambers communicate with each other differ in diameter and/or in length.

  • Patent number: 5133160
    Abstract: The invention relates to an improved method for removing point defects and oint defect clusters from semiconductor discs, which defects impair the quality of electronic components or structural elements made from such discs. According to the invention, prior to polishing, the semiconductor discs are immersed in a bath containing grains moving in a streaming carrier medium of the bath. One side of the discs are then polished and thereafter the discs are subjected to oxidation processes whereby stacking faults are induced in the rear side of the discs. These stacking faults have an excellent gettering effect on the point defects.

  • Patent number: 5117535
    Abstract: For the production of a nonwoven web from a primary nonwoven web a conventional carding drum is used as well as a collecting surface, on which a vacuum is applied and which is continuously moved and serves to collect the fibers flying from the carding drum. In order to ensure desirable conditions for the entrainment of the fibers flying off, the fibrous covering on the carding drum is sucked from consecutive layers on consecutive portions of the surface of the drum so as to from partial streams of fibers in suction passages between the carding drum and the collecting surface.

  • Patent number: 5116453
    Abstract: A thermoplastic tape is wrapped around a package and is tightened by the disclosed strapping or banding apparatus. The ends of the plastic tape can be welded together by a combined strapping and sealing apparatus or even with a separate sealing apparatus. The strapping apparatus includes a positioning system which ensures that a slotted wheel intended for tightening the plastic tape, once the operating cycle is complete, always assumes an optimum position for the re-insertion of the plastic tape. The use of the strapping apparatus is thereby substantially facilitated, since the operator normally does not have any hands free to adjust the slotted wheel that would otherwise be necessary for tape insertion.
