Patent DE-3430771-A1 (DE)
Title: Fretted stringed instrument characterised by nut-to-fret distances which differ from the physical formula hitherto applicable thereto and apparatuses for the free selection of these distances which furthermore provide the possibility of varying the position of the strings on the nut in a planned manner
Inventor: PAIERL KURT
IPC: G10D3/12
Filed: 1984-08-21
Abstract: The principal field of application of the invention can best be explained with reference to the most common fretted stringed instrument, the guitar. In this instrument, assuming the design conventional hitherto, discrepancies of tone arise which cannot be eliminated by tuning alone. This can be recognised, after tuning the free strings with a tuning device (e.g. an electronic tuning device), by comparing the tuning of the notes played with the pitch of the free strings. This comparison will show that the notes played are at a somewhat higher pitch in comparison. As a result of the invention, the two pitches are combined at the pitch of the played notes. In the case of the guitar, this is achieved by a movable nut device.

Title: Lifting system for drive-on rails
Inventor: HENSEL HEINZ
IPC: B65G69/28
Filed: 1984-11-07
Abstract: Development of the lifting system for drive-on rails has, together with a weight-optimised chassis, enabled us to produce a vehicle which, with a permitted total weight of 7490 kg, can transport two racing vehicles or similar vehicles. This weight limit was chosen, because special authorization for transport on Sundays can then be obtained. Furthermore, vehicles in this weight class are processed by customs at weekends and public holidays when borders are crossed.

Patent DE-3503978-A1 (DE)
Inventor: SCHUMACHER JUERGEN DIPL BIOL D
IPC: C12Q1/68
Filed: 1985-02-06
Abstract: It can be proved that typical modifications exist in samples of nucleic acid of ill plants. Independently from the origin location and the edge of the plants, additional bands appear during the bidimensional gel-electrophoretic separation of nucleic acids. Said supplementary nucleic acids may be tested, for example with molecular hybridation technics. Early objective diagnoses may thus be obtained, which enable to take on time the required measures to combat the disease, as well as to establish the mapping of large extensions of damages caused to plants. The test is very simple and is adapted to investigation in series.

Title: Device for reducing the throttle losses in piston engines under partial load by phase control of the valves
Inventor: GOHLE HERBERT DIPL ING
IPC: F01L9/11
Filed: 1985-06-05
Abstract: The required variability of the timing points of a valve timing gear, primarily for internal combustion engines, in order to prevent throttle losses on the intake and working stroke at partial load is achieved with recovery of the energy expended for actuation of the valve as in a conventional camshaft control in that the opening and closing process is performed by 2 different control cams running with an adjustable phase angle to the crankshaft. At the same time the valves are conventionally spring loaded in the closing direction. A hydraulic drive is chosen in which the 2 pump pistons driven by the 2 control cams function in a common pump chamber and are so controlled that the valve is opened only when both pump pistons are run out. By corresponding selection of the phase position of the four control cams - two per valve - the four timing points can be adjusted as required. <IMAGE>

Abstract: A blocking or freeing signal coming from a power supply unit (N) reaches a logic module (LB1) containing TTL components. A blocking or freeing signal for at least one peripheral module (PB) connected in series after the logic module is only triggered by a blocking or freeing signal of the power supply unit (N) when it is established by a converter (U1) which is assigned to the logic module (LB1) that the operating voltage of the logic module (LB1) has a minimum value; otherwise a blocking signal is fed to the latter. <IMAGE>
Patent DE-3522571-A1 (DE)
Title: Terrain-adjustable chassis
Inventor: FREUND KARL-HEINZ
IPC: B60G5/02
Filed: 1985-06-24
Abstract: The terrain-adjustable chassis is intended to give slow moving wheeled vehicles, such as, for example, diggers and wheel loaders, which often move in uneven terrain and constantly shift their centre of gravity due to their working movements, improved stability and driving safety. In the slow moving wheeled vehicles hitherto known the terrain- adjustment is achieved by a swing axle, whilst the other axle is rigidly mounted. As a result of this construction the stability is reduced when the centre of gravity shifts closer to the swing axle. In addition the side tilt of the vehicle is always determined by the position of the rigid axle (Fig. 1). In the terrain-adjustable chassis both axles are suspended so that they can swing and due to a transmission element can only swing towards one another in opposite directions (see Fig. 3). Ground irregularities are only half transmitted to the vehicle frame by each axle. A shifting of the vehicle's centre of gravity in the direction of one axle has scarcely any negative effect on the stability. <IMAGE>

Title: Self-clamping locking tongue for a safety-belt lock
Inventor: BORUTTA-MENSING WERNER
IPC: B60R22/18
Filed: 1985-11-30
Abstract: In a self-clamping locking tongue for a safety-belt lock, especially in motor vehicles, with a frame having a tongue-like part for locking insertion into the lock and an orifice, through which the belt band of the safety belt is guided, the belt band being clampable in the associated orifice, when the lock is locked, by a clamping member displaceable under the effect of its loop-like run, the effective clamping forces are to be increased and, in general, the design of the locking tongue is to be improved. For this purpose, the orifice (26) of the locking tongue (22) is divided by a transversely extending bar (28) and the clamping member (31) is arranged on the bar (28) so as to be displaceable in the longitudinal direction of the tongue, the belt band (10) being guided via the frame (23) into a first orifice (29), so as to penetrate between an upper frame part (27) and the clamping member (31) and then engage under the clamping member (31), and out of a second orifice (30) in the direction of the tongue part (24) out of the locking tongue (22). <IMAGE>

Title: Coarse and fine adjustment
Inventor: HAHN WOLFGANG DIPL ING
IPC: G05G1/01
Filed: 1985-12-30
Abstract: The invention relates to a coarse and fine adjustment for various use temperatures, in which a temperature-dependent output torque of the fine drive is required, with a low input torque. It is the object of the invention to design a coarse and fine drive with a known coarse adjustment in such a way that a temperature-dependent output torque of the fine drive and an optimisation of the input torque as a function of the load on the coarse and fine drive under climatically controlled conditions is achieved. This object is achieved in that the fine drive between the moveable and instrument-attached bearing is provided with at least one temperature-dependent energy accumulator for a temperature-dependent frictional drive and output drive torque and in addition to the temperature-dependent energy accumulator a temperature-independent energy accumulator is provided, the temperature-dependent energy accumulator being connected either in parallel or in series to the temperature-independent energy accumulator. It is advantageous to employ thermal-bimetallic springs for the temperature-dependent energy accumulator.

Abstract: The invention "variably adjustable handlebar shaft as lifting mechanism in twin handlebar stems for bicycles, motor cycles etc." offers a solution to the problem of adjusting the height of and of positioning the handlebars of a two-wheeler as required with the lowest conceivable complexity. This gives a practical gain for touring with its changing requirements for the rider's posture and with different riders (individual adaptation of the height of the handlebars). The variability is achieved by the additional introduction of a second handlebar stem, the horizontal fixing by guide grooves and elements and specific cross-sections, the vertical fixing by a locking screw or gear crank.
