Abstract:
The invention relates to an electronic teaching, accompaniment and practice music apparatus which is independent of a played musical instrument. The apparatus includes devices for digital sound production, tempo setting, accompaniment, operation and input of digital note data, which are connected by means of a control unit, which is connected with an electro-acoustical device for acoustical reproduction of the note sequences corresponding to the input piece of music via a digital-analog converter. There is an optical display device which is connected with a piano keyboard or a guitar fingerboard or represents these, for optical display of the note sequences played.
Abstract:
The invention relates to a vessel, particularly a pressure vessel, having a tubular housing part (10), in which a cover part (12) can be secured, characterized in that support segments (18) are inserted at least in some areas in a recess (14) on the interior (16) of the housing part (10), which segments provide support to the cover part (12) when it is installed, and that at least one fixing means (22) is provided, which ensures a releasable engagement between cover part (12) and at least one of the support segments (18).
Abstract:
A filter device, in particular, for high-pressure applications in a molten polymer filtration, has a screw-in piece (10), provided with a first threaded section (12) for fixing the filter device, and a second threaded section (14) for fixing a filter medium (16), in particular, in the form of a metal wool and with a perforated support tube (18) for the metal wool. The other free end of the filter device is provided with a volume displacer (24). The metal wool is surrounded by a support grid (20) and fixed by two fixing pieces (28, 30), held at a separation from each other by the support grid (20). One fixing piece (28) is fixed to the second threaded section (14) of the screw-in piece (10). The other fixing piece forms a handle (30) for the fixing formed. As a result of the volume displacer (24) being a one-piece component of the support tube (18) and the fixing piece (30) forming the handle covering the volume displacer (24), the filter device is significantly improved in that a simple and rapid assembly procedure for the exchangeable filter medium is provided. Also, the filter element construction is held formed to be free of damaging torsional loads.
Abstract:
A method for producing a sealing connection between a filter mat of a tubular filter element and a metallic head piece encircling the filter element at one end. The head piece has an annular groove accommodating the edge of the filter mat. In order to reduce the internal diameter of the annular groove, the wall adjacent to the periphery is compressed by the periphery of the head piece towards the interior by applying a force of pressure which is directed radially towards the interior. The wall of the annular groove adjacent to the periphery is provided with an enlargement which enlarges the diameter of the head piece. The force of pressure for compressing the wall is applied in the area of said enlargement.
Abstract:
A gas bag module for a vehicle occupant restraint system, including a housing (10) for a gas generator and a gas bag which can be unfolded by the latter, and having a cover (16, 18) which can be converted from a closed position into an open position, the cover (16, 18) being connected to the housing (10) by means of at least one hinge (30), is characterized in that the cover (16, 18) is connected to a swivel section (20) which in turn is connected to the housing (10) by means of the hinge (30).
Abstract:
The fabric part intended to be arranged in the interior of a gas bag of a vehicle occupant restraint system and comprising, when spread out flat, a generally rectangular middle section with shorter and longer outer edges as well as four fastening sections. The fastening sections are disposed at the shorter outer edges of the middle section such that each thereof extends starting from the longer outer edges along the shorter outer edges toward a longitudinal centerline of the middle section. Each of the fastening sections ends at a distance away from the longitudinal centerline.
Abstract:
A gas bag for a vehicle occupant restraint system has a wall, an inflation opening, a rim as part of the wall, surrounding the inflation opening, the gas bag being adapted to be secured to a gas generator housing in the region of the rim. The gas bag further has at least one limiting strap which is secured to the wall and has a reinforcement layer connected with the wall and at least partially covering the rim on the inner side of the gas bag. The reinforcement layer is exclusively formed by the limiting strap connected with the wall in the region of the rim.
Abstract:
A gas bag is attached to an accommodating housing of a gas bag restraining system for vehicles on the front passenger side thereof. The gas bag is provided along the edge of its rectangular inflation opening with a sewn-in reinforcing element forming a bead. The edge provided with the reinforcing element is fixed to the accommodating housing with an interference fit by means of a profile element. The attachment provides high mechanical strength along with an improved gas tightness.
