Title: Apparatus for controlling a shield driving machine
Inventor: MARX HANS-JUERGEN
IPC: E21D9/093
Filed: 1987-10-03
Abstract: An apparatus for controlling a shield driving machine consists of a measuring arrangement (1-4), detecting position parameters of the shield driving machine and having a laser-beam unit (1) which is arranged behind the tunnel driving machine in a lined tunnel section and can be directed towards a target reflector (2) on the rear of the shield driving machine, and of an electric computer (5) connected to the measuring arrangement (1-4). In the case of such an apparatus, trouble-free control of the shield driving machine is obtained with comparatively simple means when the measuring arrangement (1-4) consists of the automatically working laser-beam unit (1), transmitting electric signals corresponding to the distances (si) from the target reflector (2), the horizontal directions (ri) and vertical angles (zi), and of electric inclinometers (3, 4) arranged in the shield driving machine for the rolling ( alpha Q) and longitudinal inclination ( alpha L) of the shield driving machine, and the computer (5) is designed for continuous calculation as well as storage of the actual spatial position of the shield driving machine and the output of deviation and control values as a function of a stored desired spatial position of the shield driving machine. <IMAGE>

Title: Measuring device (transducer) for measuring a translational acceleration
Inventor: ZABLER ERICH DIPL ING
IPC: G01P15/12
Filed: 1987-10-15
Abstract: A measuring device for measuring a translational acceleration has a spring/mass system comprising a leaf spring (10) and an inertial mass (11). Strain gauges (18, 19) fastened in an insulated manner on the leaf spring (11) are connected via four contact terminals (a-d) to a Wheatstone bridge, from the balance arm of which a measurement signal can be taken. In order to achieve a phase-accurate measurement signal in a vibrational frequency range of up to approximately 150 Hz, the leaf spring (10) is made of two outer limbs (14) and a middle limb (15) lying between them, which run substantially parallel to each other and are integrally connected to one another at both of their ends. The two outer limbs (14) are centrally clamped, whilst the inertial mass (11) is centrally fastened to the middle limb (15). The strain gauges (18, 19) are arranged aligned longitudinally on the middle limb (15) (Fig. 1). <IMAGE>

Title: Device for the combustion of soot in exhaust emission control systems of motor vehicles
Inventor: BLAUHUT REINHOLD
IPC: F01N3/023
Filed: 1988-02-13
Abstract: Device for the combustion of soot in exhaust emission control systems of motor vehicles, especially of diesel motor vehicles. The separated soot is introduced into the device from a carrier gas flow. A clean gas can be drawn off from the device and fed to the exhaust system of the motor vehicle. The device is characterised by a heat exchanger with a plurality of essentially vertical clean gas ducts, around which the carrier gas flow flows in an essentially horizontal direction of flow, a filter mat, which covers the upper openings of the clean gas ducts, and an arrangement of combustion electrodes, which are arranged above the filter mat and are alternately connected to the positive or the negative pole of a voltage source. A deflection device, which deflects the carrier gas flow towards the filter mat, is arranged downstream of the clean gas port in the direction of flow of the carrier gas flow. The distance of the combustion electrodes from the filter mat is selected so that the deposited soot comes in contact with the combustion electrodes. <IMAGE>

Title: Device for connecting a gas consumer to a liquefied-gas cartridge
Inventor: SCREMIN H GERARD
IPC: F23D14/28
Filed: 1988-04-28
Abstract: The invention relates to a device for connecting a gas consumer to a liquefied-gas cartridge which has in its cap a valve housing which for gas delivery can be connected to a coupling piece of the gas consumer or its associated extraction device. Known devices of this type have the disadvantage that the screwing of the coupling piece onto the external thread of the valve housing is problematic especially in the cases in which the cartridge is to be repeatedly attached to different gas consumers, since the threads of the coupling piece and the valve housing can be damaged by repeatedly releasing them and screwing them together again. This disadvantage is removed according to the invention owing to the fact that the connecting device has a head (1) which can be put onto the valve housing (10) of the liquefied-gas cartridge (11) and has elastically deformable arms (2) which enclose the valve housing (10) and can be clamped in place on the peripheral surface (12) of the valve housing by axially displacing the head (1). Connection of pressure-gas cartridges to all sorts of consumers. <IMAGE>

Title: Sun umbrella
Inventor: STROMEYER MARKUS
IPC: A45B25/14
Filed: 1988-06-16
Abstract: The sun umbrella has a two-part stand (11), both parts of which are inserted telescopically one inside the other. Arranged in one stand part (16) is a threaded spindle (23) and in the other part (27) a nut piece (28) which allows the height of the sun umbrella to be adjusted continuously and with little effort, and which prevents the umbrella from lowering unintentionally. The umbrella (12) is preferably fixed, by means of an articulated coupling (32, 36), to the part of the stand constructed as a self-supporting carrier (31). The sleeve (36) of the articulated coupling has a lateral opening (38) provided for introducing or removing the joint ball (32). This design allows the umbrella to be turned freely about its axis and prevents the articulated coupling from being opened and the umbrella from dropping down when it is turned. <IMAGE>

Title: Brake disc for disc brakes
Inventor: METZLER HORST
IPC: F16D65/12
Filed: 1988-07-08
Abstract: A brake disc for disc brakes has a disc ring which comprises at least one friction ring and is composed of a cast material. This disc ring is attached to an inner part, likewise composed of a cast material. To take account of the differing thermal and mechanical stresses on the disc ring and the inner part and in order to connect these two parts in a suitable manner, the proposal is that the inner part should be composed of a material with a higher tensile strength than the material of the disc ring and that the inner part and the disc ring should have a flange-type connection to which the disc ring together with the inner part is connected by brazing.

Title: Potentiostatic sensor
Inventor: REISS GERHARD DR
IPC: G01N27/40
Filed: 1988-09-20
Abstract: A potentiostatic sensor is specified which has a working electrode and at least one further electrode (12, 14), which are arranged in an electrolyte space, filled with electrolyte (25), in a housing (3) provided with an opening, the opening being closed by means of a diaphragm (4) on which the working electrode is arranged. Such a potentiostatic sensor exhibits the problem that the diaphragm often folds during assembly on the housing, if it is fastened there with the aid of a screw, or is stretched, which leads to defects in the diaphragm, if the diaphragm is tensioned. By means of the invention, a sensor is specified which is easy to produce and has small tolerances in the diaphragm dimensions. Additionally, the diaphragm (4) is connected to the housing (3) by means of adhesion. <IMAGE>
