Patent DE-4005287-A1 (DE)
Title: Structural beam in long goods wagon - replaces wooden floor in central section to allow increased beam depth
Inventor: BERNDT WERNER
IPC: B61D17/10
Filed: 1990-02-20
Abstract: Long goods wagons are normally made with wooden floors which are supported on longitudinal beams. In order to provide a middle beam of the necessary strength to carry the load imposed on the wagon floor the depth of the beam at is mid-point must be as great as possible without reducing the necessary ground clearance of the wagon. This problem is overcome by shaping the longitudinal beam (1) so that the upper flange over the middle part of the beam forms the wagon floor. The depth of the beam is thus increased without reducing the wagon ground clearance. USE/ADVANTAGE - Elongated railway goods wagon with longitudinal structural beams of max length in centre section.
Patent DE-4008002-A1 (DE)
Inventor: SCHABERT HANS-PETER DIPL ING
IPC: F16K31/04
Filed: 1990-03-13
Abstract: With motor-driven actuators for a control element (4) having a defined locking position, for example a fixed end stop, care must be taken to ensure that in the locked position the control element is clamped with a defined torque. According to the invention therefore, the maximum torque available on the motor (2) is increased after the control element starts to move into a locked position. In an advantageous embodiment of the process for an actuator with an electric motor, the reaching of the locked position is monitored by measuring the motor current and the torque is increased by controlling an actual voltage applied to the electric motor. A device for carrying out the process is also disclosed.

Title: Mfr. of foam-core metal-skin door panels - comprises foaming between two continuous steel sheets which are restrained by system of small air jets
Inventor: HOERMANN STEPHAN DIPL PHYS
IPC: B29C44/32
Filed: 1990-12-17
Abstract: A foam-cored profile section of metal sheet (steel or Al in particular) or other material with similar non-porous surfaces, pref. for a panel of a multiple-member door (esp. a sliding type, etc.) is produced in continuous length and cut off to lengths required. The process uses a forming system on both sides of the material width which is made of, e.g., Al and has a series of air chambers, pref. extending across its cross-section; these chambers are thus longitudinal in the process and they all have a number of bores along their length of sufficiently small dia. to produce air cushions between the sides of the prod. and themselves whilst only using small vols. of air flow; these air cushions thus only require air to cover their losses while the metal profiles move along over the bores. ADVANTAGE - The system supports the thin skins (for saving wt.) of the prod. without allowing them to be deformed.

Title: Preventing germination of weeds in agriculture - by simulating night-time conditions by encapsulating plough in light impermeable material
Inventor: WASSEN HANS
IPC: A01B79/00
Filed: 1991-03-28
Abstract: The method of eliminating the propagation of weeds in agriculture prevents the weed seeds from germinating. It works by excluding sunlight and ploughing in the dark. This is achieved by encapsulating the ploug in light impermeable material fastened to skids (3) on either side of the plough. All the controls are outside the capsule.

Patent DE-4114492-A1 (DE)
IPC: B23K26/06
Filed: 1991-05-03
Abstract: In a process for machining a material using a laser, with detection of the material to be machined, laser light is directed onto the material through a laser optical system and the light re-emitted by the material is directed onto a first detector arrangement which measures its intensity. An evaluation circuit which controls the output or energy of the laser is connected after the detector arrangement. The energy supplied to the material through the laser optical system is measured and the detector arrangement sends to the evaluation circuit a display signal which indicates the beginning of the dielectric breakdown. The evaluation circuit reduces the output of the laser and/or interrupts the laser pulse if at a given time at which a given energy has been supplied to the material a display signal has not yet appeared.
