Abstract: Methods and apparatuses for producing battery cell stacks in which a first and second electrode string with separator web and first and second electrodes attached thereto at a distance are combined together to form a composite string and mono-cells are separated therefrom. To form terminal cells, a second electrode is omitted in each case at some locations during the production of the second electrode string, so that a length section of the respective separator web is produced without the corresponding second electrode. A terminal cell region is then formed in the composite string, in which a first electrode is inserted between separator web length sections. This is separated when the cells are separated from the composite string to form a terminal cell. Subsequent stacking can then begin or terminate with an end cell. Also a computer program for performing the method.

Abstract: An method for providing an electrode string which has a separator web and electrode segments attached thereto at a distance from one another by: a) providing a web-shaped electrode substrate; b) picking up the web-shaped electrode substrate with a transport system having transport units individually movable along a guide track, and moving the electrode substrate in a planar manner along a cutting plane; c) cutting the web-shaped electrode substrate in the cutting plane in order to cut off electrode segments which are each arranged individually on one of the transport units; d) adjusting a distance between cut electrode segments with relative movement of the transport units in order to position the electrode segments relative to one another; e) providing a separator web; f) applying and fixing the electrode segments positioned relative to one another on the separator web.

Abstract: An apparatus for supporting a user includes a faceplate, an arm, a bridge, and a base. The bridge is rotatably attached to the faceplate to allow the faceplate to be pivotably adjusted. The bridge includes a hub with first and second hub bodies. Locking pins on the hub bodies slidingly engage pivot adjustment holes in first and second pivot adjustment rings. First and second buttons can be depressed to slide the hub bodies inwardly to separate the locking pins from the pivot adjustment holes to allow the hub to rotate, thereby allowing the faceplate to pivot. When the buttons are released, the hub bodies slide outwardly to insert the locking pins into the same or different pivot adjustment holes to prevent the hub from rotating.

Abstract: A device for manufacturing a cell stack having a plurality of cell assemblies. The device comprises several positioning units accommodating the plurality of cell assemblies. The positioning units each comprise a positioning jaw enclosing the plurality of cell assemblies disposed one above the other. The device further comprises a first moving unit moving the positioning unit. The first moving unit comprises a moving plate mounted in a movable manner and an actuator. The positioning units are disposed on the moving plate. The actuator moves the moving plate. The positioning units are arranged such that the individual cell assemblies are centered between the positioning jaws by the movement initiated by the first moving unit. Finally, the device comprises a support, which is decoupled from the movement of the first moving unit, wherein the plurality of cell assemblies and/or plies rest on the support.

Abstract: An apparatus for supporting a user includes a faceplate, an arm, and a base. The faceplate has an opening to receive a user's face. The arm is attached to the faceplate and the base. The base includes a base slide that is slidable within a slot of a base body. The base slide includes one or more lock pins that releasably engage one of multiple holes in a lock bar. The lock bar is mechanically coupled to a button body. When the button body is pulled distally, the lock bar moves away from the base slide such that the lock pin(s) is/are removed from the corresponding hole(s) to allow the base slide to slide within the slot. When the button body is released, the lock bar moves towards the base slide such that the lock pin(s) is/are inserted into the same or different hole(s) to lock the slide's position.

Abstract: A electric circuit includes a connection to a current source, an electric load, and a thermal-mechanical fuse which, in the case of failure at an excessive heat emission, interrupts the current supply to the load, which is effectuated by a feeder in which is arranged a spring having two ends, at least one end is soldered to a solder point provided in the feed line. The one solder point is under a mechanical pretension caused by the restoring force of a spring, that separates the solder joint between the spring and the solder point in the feed line, when the solder melts at the solder point.

Abstract: A simplified and economical power supply for redundant computer systems of control systems is disclosed. These control systems may include burner control for furnaces. The safety and reliability of the system are increased. The power supply comprises one single common voltage supply in the form of a self-monitoring power pack unit SN having a power pack NT, an undervoltage monitor UW and an overvoltage monitor. The self-monitoring power pack unit communicates with the redundant computer units P1, P2 via a supply line 1e. This single self-monitoring power pack unit is used according to the invention instead of the known fully parallel two-channel operation with two computer units and two power packs with appertaining components and supply lines. The overvoltage monitor UW and the undervoltage monitor UW are preferably checked for operability through the periodic transmission of a test signal.
