Title: Stopping of motor driven pressure pump of unit for coating workpieces - using atomised liquid coating material with empty material storage container or leakage of material supply from container to pump or from pump to atomising organ
Inventor: KUEHNL RUDOLF
IPC: B05B12/08
Filed: 1992-07-29
Abstract: The pressure and/or the vol. flow at the pump output and/or the pump piston speed, or a value continuously measured depending on this is taken. The resulting values using the sensors (19,20,21) are converted in to electrical signals which are fed into an electronic evaluation unit (23). If during the working operation the pressure and/or the vol. flow fails to reach a specified value, and/or the piston speed fails to reach a specified speed, the output signals from the electronic evaluation unit operate a control, so that the electrically controlled drive connection between the motor (13) and the pump or the electrical supply to the pump motor is interrupted. ADVANTAGE - Pump motor is automatically switched off, if no material is to be found in pump chamber.

Title: Multi-needle sewing machine thread cutting - cuts lower thread while needles are at bottom dead centre and upper threads when they are at top dead centre
Inventor: MITSUJI TOSHIRO
IPC: D05B1/10
Filed: 1992-10-23
Abstract: To cut the upper and lower thread, in a sewing machine, the lower thread is severed when the needles are held at their lower dead centre position of its movement. The upper threads (1a) are cut together when the needles are held near their upper dead centre position of movement. The upper and lower threads are cut at the cylinder baseplate. The cylinder baseplate, with the needle plate, has an axial movement. A number of needles move vertically through the upper and lower sides of the needle plate, while a looper moves to and fro below the needle plate according to the vertical movement of the needles. A fixed blade is opposite a working end of the looper when it is retracted, and a second fixed blade is opposite the vertical movement path of the needles. ADVANTAGE - The technique gives an effective thread cutting action on an industrial multi-needle sewing machine with a covering chain stitch action, and a cylindrical baseplate, where the cuts threads are held securely

IPC: G01C11/00
Filed: 1994-06-03
Abstract: The invention concerns a method for the collection, analysis, measurement and storage of geographical data, the aim being to guarantee user-relevant data handling and simplified availability in large, medium and small user centres and to ensures the optimization of existing components in digital stereo work stations with facilities for interactive overlay, truing and execution of digitally recorded landscape, planning and property data or land-register maps as well as the addition of alphanumeric data. This aim is achieved as shown in the figure by virtue of the fact that a topographic surface (zone 1) is recorded using aerial photography by an aircraft (2) whose position is determined by means of DGPS signals from satellites (3). A digital height model (4) is subsequently derived by data processing or calculated after the fourth operational step. From the topographic surface (zone 1) and the digital height model, including the known positions of the projection centres at the time the photograph was taken by the aircraft (2), and by mathematical transformation of the analogue aerial photo or of a digital aerial-photo scene, the digital orthophoto (5) is generated and made available to a potential user on a data-storage medium, thus enabling the potential user to add, to the digital orthophoto (5), vector/line graphics (6) and to make use of it depending on the task specification and necessary decision-making capacity which he, as mandator, has formulated.
