Title: Coin tester for distinguishing coins having a smooth or a grooved edge
Inventor: HAUENSTEIN GUENTHER DIPL ING
IPC: G07D5/10
Filed: 1984-07-24
Abstract: A free end (5) of a pivoting arm (6) engages into a coin channel (1) and, in its position of rest, guides a coin (3), previously rejected by a sensor (22), via a longitudinal rib (15) to a rejection channel (16). A coin (3) found to be good triggers a short pulse on a solenoid magnet (9) which brings the pivoting arm (6) into its working position. A leaf spring (12) now senses the coin edge with its free end face (13). A coin (3) having a smooth edge slips through unimpeded and is deflected into a good channel (21) by a transverse rib (14) within the pulse duration. A knurled coin (3) is stopped and, after the pulse, rolls over the good channel (21), now closed by the longitudinal rib (15), to the rejection channel (16). The device is suitable for coin-operated telephones and can be fed from the telephone loop. <IMAGE>

Title: Looping tower for metal strips
Inventor: NICKEL HORST DIPL ING
IPC: C21D9/56
Filed: 1984-11-15
Abstract: The invention relates to a looping tower for metal strips of low buckling resistance. The free-running deflecting rollers (2, 3, 4, 6, 7, 9) having an anti-slip covering are directly preceded by deflecting rollers (10-15) which are crowned on the strip side located opposite the deflecting roller and which have a substantially smaller diameter. By means of these smaller deflecting rollers, the strip is curved convexly in such a way that it first runs onto the deflecting roller with the middle of the strip. A folding of the strip in the region of the looping tower is thereby prevented. <IMAGE>

Title: Silencer for an internal combustion engine
Inventor: WAGNER WALTER
IPC: F01N1/08
Filed: 1985-02-22
Abstract: A silencer for an internal combustion engine comprises an outer jacket tube (1), which at the end is closed by cover plates (2, 3) except for through-apertures (4, 5) for gas conducting pipes (6, 7) on the inlet and outlet side. The gas conducting pipes (6, 7) on the inlet and outlet side each have a closed and a perforated section, the closed section in each case being located inside the chambers (19, 21) forming the end closures of the silencer, which chambers in an axial direction are defined by intermediate bases (10, 11) and the cover plates (2, 3), whereas the perforated sections extend inside the area axially bounded by the intermediate bases (10, 11). Inside the chamber between the intermediate bases (10, 11) extends an inner jacket tube (24), which encloses the perforated section of the gas conducting pipe (7) and which is designed in such a way that it subdivides the chamber between the intermediate bases (10, 11) into a total of three chambers. In addition to effective silencing due to five resonator chambers arranged in series, in particular any seepage of condensate out of the silencer pot and hence any blockage caused in the lower pipe sections by icing of the same, especially in winter operation, are effectively prevented. <IMAGE>

Title: Multi-purpose furniture constructed as a bed
Inventor: ABE HANS JOACHIM
IPC: A47D5/00
Filed: 1985-05-17
Abstract: The multi-purpose furniture which is constructed as a bed can be dismantled by hand. The two end parts (1, 2) consist mainly in each case of two vertical posts (8, 9) and rungs (13) running horizontally between said posts and located with spacing one above the other. The rest (14) constructed as a bedstead can be hooked into the rungs (13) selectively in different positions of height. When the rest (14) has been hooked in, a stable and sturdy bed is obtained which, if the rest (14) is hooked in at an appropriate height, can be used as a play house and, by means of an additional part of approximately wedge-shaped construction which can be hooked into the rungs (13), forms a desk or drawing table, an infant changing table, etc. The bed side parts (3, 4) are likewise hooked into the rungs (13). The multi-purpose furniture requires no fittings at all, thus ruling out any risk of injury, it can easily be dismantled for dispatch and can be set up without difficulty in multi-functional use, even by those who have no practice in this respect. <IMAGE>
Patent DE-3518517-A1 (DE)
Title: Drive device
Inventor: JOCHUM PETER
IPC: B25B27/00
Filed: 1985-05-23
Abstract: The drive device has an output member (1) which in a first step performs an axial movement. After this axial movement is performed, the pressure body (6) rapidly traversing beforehand with the output member (1) runs axially further relative to the output member (1) on account of its kinetic energy. Due to a helix-like connection between the pressure body (6) and the output member (1), rotation of the output member (1) thus occurs in a second step. Such a drive device is suitable, for example, for the rapid setting of self-tapping screws in hard receiving materials which have not been pre-drilled. <IMAGE>

Patent DE-3614302-A1 (DE)
Title: Front wall with support at the headbox of a papermachine
Inventor: HILDEBRAND OTTO ING GRAD
IPC: D21F1/02
Filed: 1986-04-26
Abstract: The front wall (1) takes the form of a stiff girder (2). The latter is arranged above a nozzle chamber (3) across the entire machine width. Owing to its dead weight and owing to the pressure and temperature conditions in the nozzle chamber (3), the girder (2) is deformed. To counteract these deforming effects, the girder (2) is supported on a supporting girder (4) having approximately the same length as the girder (2) itself. In order to obtain a substantially lower construction, the supporting girder (4) is arranged relative to the girder (2) in such a way that an interspace is left free between it and the lower wall (6) of the girder. It serves for accommodating force-emitting supporting elements (7) between the box girder (2) and the support girder (4). Each of the supporting elements is intended for only a part of the area to be supported in the interspace. According to a preferred embodiment, the girder (2) is a box girder having an I-profile standing on edge and is accommodated in the cavity of the box girder. Preferably, the supporting elements (7) extending parallel to the longitudinal axis of the front wall (1) are elastic hoses which are closed at both ends and are connected individually to at least one pressure source. <IMAGE>

Title: Circuit arrangement for activating a load using a microprocessor
Inventor: HAUBNER GEORG
IPC: G05B19/042
Filed: 1986-07-17
Abstract: In an external circuit arrangement for a microprocessor, for activating and displaying a load using the microprocessor, only one common input and output, or a common line for the microprocessor, is required. It is assumed that the load can also be switched on using a manually activated switch. If the manual switch is not activated, the load can be switched via the common connection of the microprocessor, using "1" and "0" signals. If the manual switch is activated, this is recognised via the same connection of the microprocessor, by multiple polling using several pulses. If the manual switch is activated, the connection is forced to "0" potential, whereas in the other case the connection can output either "1" or "0" signals according to choice. <IMAGE>
Patent DE-3632668-A1 (DE)
Title: Additional, geometrically accurate, fixedly mounted weight for improving the driving properties in winter operation, in the case of a passenger vehicle with conventional drive, making use of the cavity in the rim bowl of the spare wheel
Inventor: LEINBERGER CURT
IPC: B62D37/04
Filed: 1986-09-26
Abstract: By virtue of the arrangement of the spare wheel lying in a trough underneath the boot floor in the rear region of the passenger vehicle, it is possible to mount a geometrically accurate weight unit in the cavity of the rim bowl. By mounting the weight behind the driving axle, the weight is additionally increased by a lever arm. This has the consequence that a higher contact-pressure force acts on the driving wheels, which results in a clear improvement in the driving properties in winter. The fixed mounting on the vehicle improves the passive and active safety of the vehicle passengers. The retaining cables provided ensure problem-free handling with the weight unit. The available boot capacity is not reduced by the weight unit. The weights can be used universally and are not dependent on the type of passenger vehicle. Three (3) models of different construction and weight with the same volume are available depending on the user's requirements.

Title: Recirculating ball screw
Inventor: BESENBECK REINHARD
IPC: F16H25/22
Filed: 1986-10-16
Abstract: A recirculating ball screw has a spindle, a spindle nut, balls situated between them and a ball recirculator (4) situated radially to the outside of the thread. The ball recirculator is accommodated in the region of the outer circumferential surface, within the cross-section of the spindle nut, a return channel (7) being provided which is formed by complementary part cross-sections within a cover (6) and the nut shell (13). The cover (6) is accommodated in a longitudinal groove (5) of corresponding profile. The return channel (7) is approximately S-shaped with ends which lead in a three-dimensionally curved manner to the thread flutes. The essential point here is that the return channel has, adjoining each of its two openings (8), at the outside, a deflecting portion (10), the centre line of which forms a three-dimensional space curve with a circumferential component and an axial component. Gentle deflection of the balls with particularly good running properties is thereby provided within a small space (Fig. 4). <IMAGE>
