Title: Transmission arrangement for vehicles, especially passenger motor vehicles
Inventor: NITESCU GHEORGHE PROF DR
IPC: F16H37/02
Filed: 1987-02-04
Abstract: A transmission arrangement for a vehicle, especially a passenger motor vehicle, has an infinitely variable transmission (3), formed from a cone-pulley transmission, and a constant ratio transmission (2) arranged parallel thereto, which can be alternatively selected by way of alternately engageable clutches (20, 30). In addition a reverse gear mechanism for reversing the direction of rotation and an axle drive ratio transmission (6), connected to the output side of both transmissions (2, 3) are provided. In order to reduce the total number of shift elements required for the individual driving positions of a passenger motor vehicle and in addition to minimise the number of shift elements engaged in the individual driving positions, it is proposed that a planetary gear (4, 5) be respectively connected to the gear train (2) and the infinitely variable transmission (3) on the input side and that the alternately engageable clutches (20, 30) each be designed for the rigid connection of two elements (14, 16; 23, 27) respectively of the planetary gear. <IMAGE>

Title: Sealing arrangement with a sealing ring insertable into an annular groove
Inventor: STALTMEIR JOSEF DIPL ING
IPC: F16J15/48
Filed: 1987-02-04
Abstract: The sealing arrangement has a flexible sealing ring (1) which is inserted into an annular groove (13) in one part (14) and the foot of which is split for sealing contact with the side walls of the annular groove (18). The head (2) of the sealing ring (1) is of asymmetrical design and it has a surface portion (4) which rises from the side wall (15) not subject to pressure to another side wall at least in the vicinity of the wall subject to pressure and ends in a sealing edge (7). The unpressurised side wall (15) can, if required, be designed with lubricant-filled recesses (11, 12) for reducing its frictional resistance against the side wall (15) of the annular groove (13). The sealing arrangement ensures that the sealing ring (1) always experiences a sufficiently high effective pressurisation towards the other part (17) only in the case of low friction relative to the side wall (15) of the annular groove (13) facing away from the pressurisation, with the result that it is always able to follow movements of the other parts (17) due to play while maintaining sealing contact with the latter. <IMAGE>

Title: Collapsible luggage frame for cars which is independent of the body work
Inventor: STOLZ JUERGEN
IPC: B60R9/06
Filed: 1987-05-27
Abstract: In order to transport awkwardly shaped items, especially bicycles, using cars or similar vehicles, a device is provided which is assigned to the rear of the vehicle and is fastened to the chassis. This means that the handling characteristics of the vehicle are considerably improved or the existing handling characteristics are not impaired by the transporting device. The device is made easy to mount and dismount by the fact that the supports are provided with plug-in supports which are arranged at right angles to them and correspond with hollow tubes assigned to the chassis. The plug-in supports can therefore be slid into the hollow tubes and can be fastened in or on the latter. A joint which can be made rigid and subdivides the support at about the level of the boot lid makes it possible to ensure that the interior of the boot is accessible even when the transporting device is mounted. The joint which can be made rigid makes it possible to pivot the upper part of the support upwards after the bicycles have been mounted on it or to execute a corresponding lowering action into the transporting position. <IMAGE>

Patent DE-3720653-A1 (DE)
Title: Method and device for measuring the speed of vehicles
Inventor: DEHL ARNOLD
IPC: G01P3/66
Filed: 1987-06-23
Abstract: In the method for measuring the speed of vehicles on a measurement section of known length, the voltage pulses produced by the loads in the detector cables when they are driven over are firstly differentiated by an electronic circuit, amplified and subsequently fed to a fast analog/digital converter which enables the signals obtained to be evaluated by computer. Digital pulse recognition by means of numerical integration of the rise in the signal of the received voltage pulse is performed in the computer. The precise drive-over instant is determined for each detector cable by providing that after the maximum value of the received voltage pulse is exceeded the zero crossing is detected by the computer and fixed as measuring point for time measurement in order to determine the driving (road) speed. In order to ensure a unique vehicle identification when measuring speed, the signals coming from an induction loop arranged upstream of or between the detector cables are linked to the voltage pulses coming from the detector cables in such a way that there is produced from the received signals and voltage pulses a pulse combination which can be evaluated in the computer in order to prevent erroneous measurement due to a plurality of vehicle axles.

Patent DE-3734542-A1 (DE)
Title: Electromagnetic seat valve
Inventor: JOSSI ARMIN
IPC: H01F7/16
Filed: 1987-10-13
Abstract: A magnetic core (16) which contains a winding (17) interacts with a wet armature (31) which is arranged in a valve chamber (28). Connected to the wet armature (31) is a closing part (38) which can be lifted off a valve seat (39), against the influence of a spring (37), when the winding (17) is energised. In order to design the magnetic circuit to have as low a reluctance as possible (as low a resistance as possible), to keep induced eddy currents to a minimum and to avoid the armature (31) sticking to the core (16) when the winding (17) is de-energised, the pot-type magnetic core (16) is constructed integrally and is provided with at least one radial slot (23). The closing part, which can be lifted off the valve seat (39) against the flow direction, is formed by a spherical surface (38) provided at the end of a shaft (34) which is mounted on the wet armature (31). An annular, burr-like projection is provided on at least one of the free pole surfaces (32, 33) of the pot-type magnetic core (16) or on that side of the wet armature (31) facing these surfaces, which projection prevents the wet armature (31) making flat contact with the said pole surfaces (32, 33) when the winding (17) is energised. <IMAGE>

Patent DE-3741345-A1 (DE)
Title: Anchoring process for fastening elements
Inventor: LEIBHARD ERICH
IPC: E04B1/41
Filed: 1987-12-07
Abstract: The anchoring of a fastening element (2) in the tension zone, susceptible to cracks, of a structure takes place in that grooves (3b) running in the wall of the bore (3a) in the axial direction are provided before the hardening bonding composition (4) is introduced. The grooves (3b) guide a crack (3c) through the bonding composition (4) radially inwards towards the fastening element (2) and along part of the circumference of the fastening element (2). Between the grooves (3b), the reduction in cross-section brings about points of weakening in the bonding composition (4), in the region of which there is guided a crack (3c) running through the bore (3a). Annular beads (2d) arranged on the fastening element (2) result in a positively locking connection with the bonding composition (4) and they ensure that the anchorage value is maintained, even when the crack (3c) opens up. <IMAGE>

Title: Return cam on the camshaft, by way of the device for return valves, especially for internal combustion engines
Inventor: FIRUS GUSTAV
IPC: F01L1/30
Filed: 1988-07-05
Abstract: By means of the return cams in addition to the main cams on the camshaft, the valves are returned by way of the device. Valve springs are thereby not necessary. The main cam and the return cam form one unit so that a precise valve timing is made possible according to the form of the main cam. The engine is free of the force generated for the valves. As a result, the main cam form can lift to a greater degree so that the valves open further. In addition the form at the tip of the main cam is round and broader so that the valve remains open longer. The engine can perform more revolutions without valve springs.
Patent DE-3826009-A1 (DE)
Title: Mounting device for the connection of a sanitary mixer fitting
IPC: E03C1/042
Filed: 1988-07-30
Abstract: In order to fasten a sanitary mixer fitting (2) on a connection housing (1), to which the water lines are guided in parallel, different insert elements (4, 5) are provided for ordered and unordered arrangements. The connection housing (1) exhibits a central bore (17) in its upper housing part (11). From the base (19) of the central bore (17), an off-centre, axis-parallel bore (15) extends as branch line to one water line. A blind hole (14) in the central part of the base (19) provides a connection to the other water line. An upper central bore (21) of the same type is also located in the housing (20) of the fitting (2), in the case of which housing there is centrally provided a bore (23) for the connection of the fitting (2). The second connection leads through an off-centre bore (25) into the upper central bore (21). A pipe piece (5) is inserted, on the one hand, into the blind bore (14) in a sealing manner and, on the other hand, into the bore (23) in the housing (20) of the fitting. When the hot water and cold water are interchanged in an unordered manner, use is made, in place of the pipe piece (5), of a distributor (4) which, by means of a radial flange (42), subdivides the two central bores (17, 21) in a sealing manner. By means of two parallel longitudinal bores (45, 46), which open into bores with mutually opposite connection stubs (40, 41), the crossover of the water path is effected. The distributor (4) is introduced rotatably into the connection housing (1), with the result that all types of mounting can be dealt with. <IMAGE>
