Title: Method and apparatus for the sectional construction of prestressed-concrete bridges independently of terrain
Inventor: LOHMILLER HERMANN DR ING
IPC: E01D21/10
Filed: 1987-10-05
Abstract: For the construction, independently of terrain, of a continuous prestressed-concrete bridge in a plurality of stages with a construction section of span width, use is made of supporting scaffolding situated thereabove, which spans from one pier to the next and is at the same time supported on the last finished stage. The individual stages can consist of mix-in-situ concrete or of a group of lined-up precast parts (segments). Here, the stages are constructed successively only in the advancing direction of the scaffold. This falsework or erecting scaffolding is designed as a spanned temporary bridge with a tower which is mounted fixedly thereon and, in the working position, is situated above the pier in front of the construction section to be constructed. Individual stage ends are connected to the top of the tower by means of tension members and from there to the finished superstructure above the projecting pier. By controlling and monitoring the forces in the individual tension members, the stresses on the superstructure are minimised, so that the material requirement for the latter is no greater than in the case where a construction section is produced in one piece.

Title: Film-like, tamper-proof sign
Inventor: MINET WILHELM
IPC: G09F7/12
Filed: 1987-12-02
Abstract: The tamper-proof sign is constructed with two film-like sections (11a, 11b) which are fixed in an abutting manner to the same base to be labelled. One of the sections (11a) is glued to the base. It is weakened in such a way that when this section is removed from the base the film is destroyed. According to the invention, provision is made for a sign carrier (1) which is to be fastened to the base and which covers the first, glued-on section (11a). The sign carrier (1) serves as a frame for the second section (11b) of the film sign, which section can be inserted into the sign carrier (1) in such a manner that it abuts against the first section (11a) and produces the complete sign. The second sign section (11b) can be removed from the frame of the sign carrier (1). <IMAGE>

Patent DE-3816245-A1 (DE)
Title: Exhaust-air cleaning device
Inventor: STROITZ WINIFRED
IPC: B01D46/00
Filed: 1988-05-11
Abstract: The present invention relates to a novel method and a novel device for exhaust-air cleaning by means of four stages: magnetic separator, wool separator, electrostatic precipitator and chemical filter. A pipe system collects the exhaust air and, using a special pipe structure, distributes it uniformly in the cleaning part. A magnetic separator removes the magnetizable particles from the exhaust air, which magnetizable particles are collected in an antimagnetic drawer. Both the use of a magnetic separator for this purpose and the antimagnetic drawer are novelties. A wool separator, a specially arranged mesh grid, separates wool-like particles. The construction of this filter stage permits - a novelty - automatic cleaning of the filter when the device is switched off and prevents clogging of the filter. The wool particles are likewise collected by the antimagnetic drawer. Further cleaning stages are a commercially available electrostatic precipitator and chemical filters.

Title: Method for the control of the output pressure of a gas-technological system having a pipework system connected downstream
Inventor: STIRNBERG DIETER DR
IPC: G05D16/20
Filed: 1988-10-27
Abstract: For the control of the output pressure of a gas-technological system having a pipework system connected downstream, a method is used in which, proceeding from the desired value/actual value deviation of the output pressure a desired pressure gradient with time dp/dt, which is to be set in the pipework, is prespecified. The prespecified pressure gradient is compared with the measured actual pressure gradient and a value for the alteration of the manipulated variable is determined therefrom. Above all, a desired value for a cascaded quantity controller, which controls the quantity of gas fed into the pipework system, is derived therefrom. A uniform setting which is aligned exactly with the prespecified desired pressure is thus possible, without an oscillating behaviour occurring. Furthermore, a control is possible which is very sensitive and reacts to the first pressure waves and, furthermore, makes possible operation which is much more uniform and, in each case, runs close to the predetermined limits, by preventing the overshooting of prespecified maximum pressures. <IMAGE>

Title: System and method for measuring the hydrogen concentration in water
Inventor: PRODYOT ROY
IPC: G01N33/18
Filed: 1989-03-14
Abstract: A hydrogen concentration cell includes a first and a second electrode, and it has an electrolyte which selectively lets through hydrogen ions in between. The second electrode is exposed to a reference composition having a fixed hydrogen partial pressure, which is a function only of temperature, while the first electrode is exposed to a water source which has an unknown hydrogen concentration. The electrodes are permeable to hydrogen and the hydrogen concentration gradient induces a voltage between the electrodes. The voltage is proportional to the hydrogen concentration in the water source, which is a convenient means for measuring the hydrogen activity/concentration at operational temperatures and pressures of a light water reactor. <IMAGE>

Title: Automatic-control viscous brake for quick, smooth braking of masses with high kinetic energy
Inventor: FRIEBEL WOLF-CHRISTOPH DR ING
IPC: F16D57/02
Filed: 1989-03-21
Abstract: The automatic-control viscous brake makes possible very rapid but nevertheless smooth braking, constant in time, of bodies with great momentum. By the direct and virtually uniform transmission of mechanical braking energy to an oil, the local overheating which occurs in conventional braking systems is avoided and optimal efficiency of the viscous brake is thus guaranteed. Further advantages over conventional brakes consist in a variable, automatic controllability and in an optimal ratio of dead weight to transmittable braking power. The viscous brake is further notable for its minimal maintenance requirement and high reliability.
