Title: Adder circuit using 5211 code
Inventor: MERKLE PAUL
IPC: G06F7/491
Filed: 1988-09-03
Abstract: The adder circuit according to the subject of the invention has as its sink circuit a special circuit (4), which can also process a potential series which is not arranged by low and high potentials. This circuit (4) consists of partial circuits (25), of which the next partial circuit (25) which is triggered with high potential changes from high potential to low potential at its output when the negating circuit (27) changes from high potential to low potential at its output. The previous circuit (9), which is numbered (2) in this adder circuit, is also required in this adder circuit. Circuit (5) is a true dual full adder, because in this case one simplified dual full adder is not enough. In this case, a partial circuit (8) is also required. A possible carry is processed in the special circuit (1), which has the opposite effect to circuit (4). <IMAGE>

Title: Alarm device
Inventor: THOMA CHRISTIAN DR
IPC: G08B17/06
Filed: 1989-02-18
Abstract: It is possible to indicate fire at an early stage by means of an alarm device in which a melting solder, shaped as a wire and acting as detector, is installed as wire loop on and/or in the area of the building which is at risk and is connected to the wiring system of the entire device. When the wire loop is severed due to heat loading occurring in the form of a fire which starts, the wiring system or, respectively, the circuit is interrupted and the alarm is triggered. It is in this case advantageous that the wire can be installed without any problems also on the outer skin of a building where it is fully active when the fire starts, even when wind or other influences are present. It can also be imagined that the wire loop is used as a wiring system, a closed-circuit current being applied to this wiring system so that, when the wire loop is severed, the alarm can be triggered, the wire having a favourable effect on the severing due to its design as a hollow wire and the integrated fluxing agent. <IMAGE>

Abstract: Packages for stacks of folded paper tissues (10) consist of very thin plastic films. To facilitate the usage, recently tear-off aids are provided, in particular in the region of a front wall (11) of the cuboid package. For opening and reclosing the package, a tear-off tab (22) is defined by perforation lines (23, 24, 25) in the region of the front wall (11), which tear-off tab can be opened and closed again with the aid of a covering adhesive tab (37). 
<??>To increase the serviceability of the film package, the tear-off tab (22), bounded by lateral perforations (23, 24) is narrower than the front wall (11), in particular in such a way that a cutout (32) is formed which is sufficient for the removal of a paper tissue (10). Adjoining the perforations of the tear-off tab (22) in the region of one front edge (26) is a transverse perforation (28, 29) which is opened by lifting the front wall of the package. By this means, a removal opening (21) is produced which extends over the full width. 
<??>In this embodiment of the tear-off aid, a design of the package is advantageous, in which folding flaps of the end wall 16 are separated from one another by punch cuts (43, 44) and can thus be folded in a rectangular shape.

IPC: B42C3/00
Filed: 1989-11-07
Abstract: For producing loose inserts (30) for envelopes, in the regions, in which the inserts (30), corresponding to the positional layout of the envelopes, are to have a distance from one another in production, there are made between neighbouring inserts (30) double cuts in the form of longitudinal cuts (25, 26) and/or in the form of transverse cuts (27, 28, 29) and thus cutoff parts (31) are cut free. The front transverse sections (39) in conveying direction (arrow 20) of the cutoff parts (31) are lifted out of the web (21) at the time of their cutting free and, after subsequent cutting free of the rear end of the cutoff part (31), drawn off. As a result, loose inserts for envelopes can be manufactured multiply lying next to one another and thus positionally accurately with high speed in such a manner that they can be transferred immediately subsequently between the cover layers of the envelopes. <IMAGE>
