Patent DE-4314343-A1 (DE)
Title: Method and device for the microfine metering of liquids
Inventor: SCHOELL KONRAD
IPC: B41J2/14
Filed: 1993-04-30
Abstract: A description is given of a method and device for the dropwise metering of liquids, in particular of inks. In this arrangement, provision is made of a capillary tube which is connected to a liquid container and is supported at its free end by a counterbearing and on which a hammer acts which is fastened to a strip-type piezoelectric element which is clamped at its opposite end. By means of corresponding excitation of the strip-type piezoelectric element, the hammer is caused to exert lateral blows on the capillary tube and squeeze this together. In the process, at each blow, a droplet is shot out, which impinges on the substrate located at a spacing from the opening of the tube. The frequency and amplitude of the excitation of the strip-type piezoelectric element are adjustable, as a result of which the expulsion can be varied.

Patent DE-4324349-A1 (DE)
Title: Soldering method for producing composite metal constructions
Inventor: ROESCH FRITZ DIPL ING
IPC: B23K1/14
Filed: 1993-07-20
Abstract: The invention provides a soldering method for producing composite metal constructions, in particular composite aluminium constructions. According to the method, a flux is used together with a eutectic-forming filler material which under the action of heat produces a metallurgical bond between the metals of the metal parts to be joined by producing a eutectic melting flow in the surface of these metal parts. Silicon is preferably used. The flux to be used must be able to remove oxide layers on the metal parts and must melt below the melting point of the metals to be joined. Potassium fluoride aluminate (NOCOLOR TM ) is preferably used here. The metal parts are locally heated in the area of the desired joint and a spot or seam joint is made.

Title: Metal-pipe press connection
Inventor: SCHULTE-HUERMANN PAUL
IPC: F16L13/14
Filed: 1993-09-01
Abstract: The two equal-diameter pipes which are to be connected are plugged into an initially smooth metal sleeve to halfway along the length of the sleeve. The border regions of the metal sleeve are flanged such that the sleeve borders rest on the pipe walls without any gaps. The space between sleeve and the pipe walls is filled by a fixedly inserted rubber sheath. Thereafter, beads (12a) are pressed into the sleeve wall with such a pressure that coinciding beads (10a) are formed in the pipe walls in each case because the material of the rubber sheath cannot yield. The connection is mechanically fixed and, in particular, due to the elongate rubber sheath, is sealed. <IMAGE>
