Abstract: A seal (8) which is produced from an elastomer and comprises a contact plate (9) which rests against the outside of the housing and forms a sealing surface (10) surrounding an outlet orifice (12) is inserted into an orifice (7) at the lower end of a housing (2) of an ink cartridge (1). A ring (11) adjacent to the top of the contact plate (9) surrounds a passage connecting to the outlet orifice (12) and leading into the interior of the housing and carries an all-round collar (13) projecting over the edge of the orifice (7) on the inside of the housing, so that the seal (8) is snapped into the orifice (7). Once the ink cartridge (1) has been inserted into a receptacle (24) of an adapter (22), with which it forms an inkjet printing head, the sealing surface (10) presses against a frame which surrounds a receiving orifice (27) of the adapter (22), which receiving orifice is connected to a nozzle plate, so that the ink path is reliably sealed.

Abstract: An electric guitar includes a hollow acoustic body, a plurality of strings, a fingerboard, air in the hollow acoustic body, and at least one speaker mounted in the hollow acoustic body. A sound system operatively associated with the strings and speaker causes sound to emanate from the speaker when the strings are played and causes sound to vibrate and resonate the hollow body and air in the hollow acoustic body.

Abstract: The invention relates to a data processing device, a method and a computer programme for computer-aided substation tendering. Conventional substation tenders rely on by-hand selection of components representing not-preengineered, not-reusable substation parts. Such tenders are inaccurate and time-consuming. In this disclosure a module (2) represents a reusable preengineered substation part and is indexed according to an intuitive multiple-index categorisation system (12), has a standardized name (14) for designating all its related files and for encoding its function in an intuitively understandable, and has a module-descriptor (3) providing standardised information (4-10) to application routines for cost calculation (1a), technical data accumulation (1d), graphics accumulation (1b) and tender text accumulation (1c).

Abstract: This apparatus (10) serves for taking a volume-adjustable sample from a fluid moving in an open channel or flowing in an unpressurized state in a pipe. The apparatus has a chamber (11) for receiving the sample and an intake/discharge line (12) which is immersed in the fluid and is connected to an opening (13) in a base (14) of the chamber. A sample outlet line (15) is arranged in the base of the chamber. The intake/discharge line opens into a vertical inner intake pipe (16). A a rotatable outer intake pipe (17) is placed over the inner intake pipe (16). The wall of the inner intake pipe (16) is provided with an axially parallel elongate hole (161) and the wall of the outer intake pipe (17) is provided with a helical elongate hole (171) extending over a rotational angle of less than 360.degree., or vice versa. The outer intake pipe is turned by a rotary actuator.
