Patent number: 8939179Abstract: A weaving machine for producing a woven fabric has a shedding device to form a loom shed of warp material, a weft insertion device for inserting a preferably tape-shaped or band-shaped weft material into the loom shed, a drawing-off device for drawing off the finished fabric in a drawing-off direction, fabric movement device for moving the fabric back and forth in the warp direction to bring the last inserted weft material into contact with the binding point or fabric edge. A shed limiter device limits the opening of the loom shed from above and below the warp, and is movable back and forth in the warp direction. The shed limiter device only loosely bounds the fabric and essentially without actively clamping or pinching or contacting the fabric and/or the last inserted weft material, at least while moving in the direction opposite the drawing-off direction.Type: GrantFiled: December 22, 2011Date of Patent: January 27, 2015Assignee: Lindauer DORNIER Gesellschaft mbHInventors: Dirk Janicijevic, Johannes Louven, Hubert Ortmann, Kurt Motz, Thomas Laukamp, Michael Langer, Herbert Mueller

Patent number: 6993320Abstract: The invention relates to a method and a device for accessing a telecommunication network and for billing telecommunication services, whereby there are presented new processes, as compared to those of classical mechanisms of network providers, services are offered to their customers and fees are charged for providing the same. In this context the invention primarily concerns novel access mechanisms and access media to a telecommunications network, modified security mechanisms as well as innovative counting methods. The invention is characterized in that authentication methods are used in the telecommunication network, which permit a subscriber to certify at any one freely choosable point in time that a payment for a service which has been solicited or which is to be solicited, is provided or has already been provided.Type: GrantFiled: June 16, 2000Date of Patent: January 31, 2006Assignee: T-Mobile Deutschland GmbHInventors: Peter Brune, Ulrike Feuser, Michael Langer, Patrik Ljungström, Uwe Michel, Walter Mohrs, Wolfgang Ptacek

Publication number: 20040244090Abstract: A climate-controlled glove for sporting activities, such as a batting glove. The glove is preferably made of leather with an inner layer of a climate-controlled material, such as polyester, used to insulate the body heat of the user in cold weather and keep the user's hands dry and comfortable in warm weather. The glove is constructed by forming a pre-existing batting glove with a glove made of the climate-controlled material, with the two sewn closely together. The two gloves work as one but allow for separation at the base of the palm. At this point, a fastening means, such as hook and loop or button, secure the gloves to one another. This enables the user to easily insert and remove a heatable material in the shape of the palm. Such may be in the form of a thin gel or similar material, thin enough to not affect the traditional usage of the glove, and provide additional padding for the user.Type: ApplicationFiled: June 4, 2003Publication date: December 9, 2004Inventor: Michael Langer

Patent number: 5073307Abstract: The invention relates to a membrane carburetor having an air filter connected upstream of the intake channel. The combustion air passes through the air filter and into the intake channel of the carburetor and coacts with the fuel drawn into the intake channel to form a fuel/air-mixture which enters the combustion chamber of the engine communicating with the intake channel. The compensation chamber of the carburetor is connected exclusively to the clean-air side of the air filter in order to avoid an overenrichment of the mixture when the filter material of the air filter becomes contaminated. The membrane carburetor can be used on two-stroke engines for portable handheld tools such as motor chain saws, cutoff machines, brushcutters or the like.Type: GrantFiled: February 5, 1990Date of Patent: December 17, 1991Assignee: Andreas StihlInventors: Michael Langer, Joachim Schommers

Patent number: 5020597Abstract: An operating string has upper and lower wipers with external seals thereon releasably connected to the operating string. A lock arrangement prevents premature release of the upper and/or lower wiper by mechanical force, but is responsive to fluid pressure in the operating string to first release the lower wiper from the operating string prior to release of the upper wiper. The upper wiper cannot be released from the operating string until the lower wiper has released from the operating string. Seals are provided to close off communication between the operating string bore and the external wiper seals to confine the pressure present in the operating string in a manner to assure release of the wipers as and when desired and in a sequence as may be desired.Type: GrantFiled: February 1, 1990Date of Patent: June 4, 1991Assignee: Texas Iron Works, Inc.Inventors: Britt O. Braddick, Michael Langer

Patent number: 5018579Abstract: A well bore operating string has upper and lower wipers thereon with the wipers releasably connected by a frangible member for releasing the wipers in response to pressure in the operating string. Seals are provided to close off communication from the operating string bore to confine the pressure present in the operating string in a manner to assure release of the wipers as and when desired and in a sequence as may be desired. Upper and lower pump down plugs sealably seat, respectively, in the upper and lower wipers to form a movable, mechanical barrier to isolate or wipe ahead of and behind a substance for movement through the operating string and subsequent discharge into the well bore.The wipers are each connected to the operating string to prevent relative rotation therebetween to further reduce the possibility of malfunction or improper functioning in releasing the wipers.Type: GrantFiled: February 1, 1990Date of Patent: May 28, 1991Assignee: Texas Iron Works, Inc.Inventors: Britt O. Braddick, Michael Langer

Patent number: 4787356Abstract: A carburetor arrangement changes the ratio of air and fuel in the air/fuel mixture for an internal combustion engine of a handheld motor-driven apparatus such as a chain saw, hedge trimmer or the like. The carburetor arrangement includes a membrane carburetor with a regulating membrane by means of which a valve needle is lifted from a valve seat against the force of a spring. The valve needle and valve seat conjointly define a valve for admitting fuel into a chamber of the carburetor. A positioning member is mounted with respect to the regulating membrane and is actuable in dependence upon the rotational speed of the engine. The actuation occurs such that the valve needle is additionally displaced a further incremental amount in response to a predetermined rotational speed of the engine thereby enriching the air/fuel mixture by an additional amount.Type: GrantFiled: June 26, 1987Date of Patent: November 29, 1988Assignee: Andreas StihlInventors: Stephan Rosgen, Michael Langer
