A piano includes an underlever assembly having an underlever arm and an underlever support joining the underlever arm to a string damper. The underlever arm is mounted to move between an at-rest position and a second position. A latch is mounted to a latch mount for movement between non-latching and latching positions. In latching position, the latch engages a latch surface of the underlever support to maintain the string damper spaced from a corresponding piano string. A stop mounted to the latch mount limits movement of the underlever arm toward its second position. A method for controlling a piano string damper includes contacting the underlever arm with the latch to maintain the string damper spaced from the string, and contacting the underlever arm with the stop to limit movement of the underlever arm.

The present application provides a method for the production of photovoltaic devices, preferably tandem solar cells. The method comprises the steps of: Providing at least one substrate comprising a front contact; and depositing at least a first semiconductor stack onto the substrate to produce a photo-voltaic device; and comprises at least two of the steps of: applying a back contact to the photovoltaic device; contacting of the photovoltaic device; removal of unnecessary material from the edge regions of the photovoltaic device; encapsulation; cross-contacting; and/or framing of the photovoltaic device, wherein the substrate is continuously or semi-continuously moved from one step of the method to the next step of the method. The present application furthermore provides a system to carry out the method of the invention.

An open end rotor spinning machine with plural workstations each having a spinning device for producing a yarn, a yarn take-off mechanism and a winding device for producing a cross-wound bobbin. The spinning device has a spinning rotor circulating in a spinning housing at high speed, a fiber band opening roller and a single motor-driven fiber band feed cylinder. The yarn take-off mechanism can be loaded by a single drive. Each workstation (2) has a mechanism (10) for defined cutting to length of a yarn (30) retrieved from the cross-wound bobbin (22), a storage mechanism (37) for receiving a specific yarn quantity and a drive mechanism (7) for lifting the cross-wound bobbin (22) from the bobbin drive roller (23). The drive (19) of the yarn take-off mechanism (18) can be reversibly driven. During the piecing process, a manually activatable control mechanism (9) activates the drive (19) of the yarn take-off mechanism (18), the drive (15) of the fiber band draw-in cylinder (14) and the drive mechanism (7) to lift the cross-wound bobbin (22) according to a predetermined piecing program.

Protective clothing comprising one protective layer or a plurality of protective layers superimposed on and optionally joined to one another may contain textile flat structures made from antiballistically acting fibers, wherein the protective layers contain contoured shapes for fitting to body shapes imparted by a molding process that is conducted without the concurrent use of a resin. The protective clothing may also contain one or more cover layers. Bulges are formed in the protective layer and optionally the cover layers by the molding process in order to produce a better fit, particularly in the bust region. Protective clothing manufactured in this way offers an agreeable degree of comfort and is particularly intended for female police, military and other security personnel.

The invention relates to an explosion-proof mat for protecting structures that enclose occupant accommodations in vehicles. The mat has several layers of textile impact-resistant sheet saturated with impregnating material and conforming to the shape of the accommodation-enclosing structure. The impregnating material is flexible after curing. A rigid sheet of composite is embedded between two inner layers of the textile sheets.

The use of carboxylic acids for controlling mycobacteria is described. The carboxylic acids contain compounds with the general formula: ##STR1## in which A is a substituted or unsubstituted Cs-Clo aryl group, A containing no nitrogen atom,R.sup.1 and R.sup.2 each independently of one other are hydrogen or a C.sub.1 -C.sub.3 alkyl group,m is 0 or 1 andn is a number from 0 to 5,and no alkyl sulphonates or alkyl sulphates are present.Said active ingredients may be used in the form of aqueous and/or alcoholic ready-for-use solutions or may be present in the form of concentrates, powders or granular products or applied to a support such as a cloth. Formulations based on said carboxylic acids may also contain other bactericidal active ingredients, synergistic effects arising in some cases.

An internet-based information system for selectively presenting data e-mails (8) from a multiplicity of data providers (X, Y), said presentation being able to be called up for a multiplicity of data recipients (E), comprises a central information server (1) having an e-mail interface unit (4), a web interface unit (10), a memory device (6), which has at least one supply memory unit (7) for storing data e-mails (8) from the data providers (X, Y), and a selection device (13), a multiplicity of data processing installations (2), which are respectively associated with a provider (X, Y) and which have an e-mail interface (5X, 5Y) which is capable of communicating with at least one provider-specific e-mail address (4X,A, 4X,B, 4Y,B, 4Y,C) for the e-mail interface unit (4) of the central information server (1), and a multiplicity of portal servers (3), which respectively have a web interface (11A, 11B, 11C) and which can be connected to the web interface unit (10) of the central information server (1). In this case, the portal servers (3) have access to specific data e-mails (8X,A, 8X,B, 8Y,B, 8Y,C) which are stored in the supply memory unit (7) and which are automatically ascertained by the selection device (13) on the basis of the identity of the respective portal server (3A, 3B, 3C), and are then able to present these data via a link on a homepage (16A, 16B, 16C), wherein the central information server (1) also has a hyperlink-identification and manipulation device (17) which can be used to automatically identify hyperlinks (18) which are present within the data e-mails (8) and to automatically manipulate said hyperlinks such that selection of a manipulated hyperlink (19) which is present in a data e-mail (8) presented via a portal server (3) first of all triggers an interrogation routine (20) for ascertaining a data-recipient-specific data record (21), the data recipient (E) being forwarded to the URL of the hyperlink (18) originally present in the data e-mail only when the interrogation routine (20) has been successfully terminated.
