Patent DE-3120139-C1 (DE)
Title: Circuit arrangement for connecting an electronic ringing tone to a two-way telephone station
Inventor: SCHARBERT JOACHIM
IPC: H04M19/04
Filed: 1981-05-20
Granted: 1982-10-28
Abstract: The invention relates to a circuit arrangement for generating audible ringing signals at a two-way telephone station, a DC voltage being obtained from an applied ringing tone with which voltage a ringing tone circuit is controlled which in turn activates a piezo transducer. The object of the invention is to produce a respective individual ringing tone depending on the telephone line which is seized by an incoming call, only a single ringing-tone-generating switching means being intended to be used and the disconnection of the two telephone lines from one another having to be guaranteed in each station condition. The ringing tone characteristic is modified and a line-specific ringing tone is thus generated by different activation of the ringing tone circuit (TSK) depending on the telephone line (a1/b1, a2/b2) which is seized by an incoming call. Only a single ringing-tone-generating switching means (PW) is used in this case. The circuit (TSK) is activated by means of a DC voltage obtained from the AC ringing voltage by means of resistors (R2/R4, R12/R14) and rectifier elements (T1/T2, T3/T4) which enable partial voltages to be tapped in each case via a rectifier circuit (G1, G3). <IMAGE>
Patent DE-3304425-C1 (DE)
Title: Device for measuring the cut sizes in tunnel linings
Inventor: BAUMANN THEODOR DR-ING
IPC: E21F17/18
Filed: 1983-02-09
Granted: 1983-12-15
Abstract: For measuring the compressive forces and bending moments arising in tunnel linings produced preferably from air-placed concrete, it has hitherto been conventional to install the measuring instruments required for this purpose directly in the material of the tunnel lining. This has the consequence, however, that the internal strains arising within the lining itself become active and thus falsify the desired measured results. In addition, the measuring instruments themselves are put at a considerable risk during the application of the lining. To remedy this, one or more separate measuring bars (1) are to be installed on the tunnel lining (9) at defined sections in such a way that they interrupt the tunnel lining through its entire thickness. This makes it possible for the forces and moments acting in the tunnel lining to be fully transmitted by the measuring bar (1) to, for example, measuring instruments (7) associated with the latter. <IMAGE>

Title: Shaft mounting in the region of a torsionally elastic shaft coupling
Inventor: DEUTSCHMANN HERBERT DIPL-ING
IPC: F16D3/80
Filed: 1985-12-21
Granted: 1987-03-05
Abstract: The invention relates to the support, in a manner secure against vibration, of shaft ends in the region of a torsionally elastic shaft coupling. In order to be able to arrange a large flywheel mass on the driving side and in order to reliably support it without the need to make the shaft diameter very large, a tubular bearing journal extending on the driven side, connected to drive-side coupling parts and supported in an outer bearing in the coupling housing, which is held rigid, is provided. In this arrangement, it is possible to connect the elastic elements of the coupling, for example the leaf springs of a Geislinger coupling in a radially inner diameter to the driving shaft, it being possible to employ a short driving shaft, thereby achieving a short overall length of the coupling.

Title: Device for preventing the unauthorised starting-up of vehicles, particularly motor vehicles
Inventor: WASCHKOWSKI EDMUND
IPC: B60R25/04
Filed: 1993-03-30
Granted: 1994-09-22
Abstract: In an already proposed device according to Patent 4,234,387, when the motor vehicle is put out of operation a bolt having contact faces is displaced axially within a tube counter to the force of a compression spring. At the same time, the contact faces form contact shells, out of which spring contacts located on the circumference of the tube are pressed. At the end position of the bolt, the latter is retained by blocking bolts. The object to be achieved is further to improve the capability of use of the device. This is achieved in that the contact faces (7) lie in one plane with the outer circumferential face of the bolt (6), and in that the spring contacts are designed as wiper contacts (34). The retention of the bolt (6) takes place by means of blocking elements (40) which are actuated indirectly or directly by a safety lock. The invention can be used in all vehicles, particularly motor vehicles. <IMAGE>

Title: Apparatus for charging stirring media (stirring bodies) into vessels
Inventor: MAROCK GUENTER
IPC: B01F15/02
Filed: 1993-11-25
Granted: 1995-01-12
Abstract: The invention relates to an apparatus for charging stirring media (stirring bodies) into vessels, having a transport apparatus for taking up a defined number of stirring media from an access area of a storage vessel and for delivering these via at least one filling funnel having at least one vessel arranged beneath, the transport apparatus having a low-pressure chamber for drawing in and holding the stirring media which is connected to a vacuum system. The low-pressure chamber is mounted so as to be able to pivot using a horizontal axle suspended above the access region of the storage vessel as a part of the transport apparatus. The transport apparatus swings to and fro about this axle between an uptake position and a delivery position. In the uptake position to take in the stirring media, it comes into at least partial contact with these. Between the transport apparatus and the storage vessel or its suspension is arranged a pneumatic drive to produce the pivoting motion of the transport apparatus. By means of this apparatus it is possible to charge small amounts of stirring bodies into the appropriate vessels rapidly and reliably with only one pivoting motion.
