Title: Three-dimensional television system
Inventor: LANGE ROBERT
IPC: H04N13/00
Filed: 1984-02-02
Abstract: In conventional 3-D television methods, two images are used for generating one image. This presented problems for the viewer since the image was floating (unstable X axis). This occurred due to the fact that the spatial image due to the two images was only stabilised in the Y axis in the brain. In the television method, this problem is solved, according to the invention, by the fact that the viewer is provided with 4 images and the brain then generates a stable fixed point from these. These 4 images are successively radiated over the television screen, crossed over in accordance with the following arrangement: first the top left image, followed by the top right image, followed by the bottom left image and lastly the bottom right image is radiated. These four images are fused to form one spatial image in the brain of the viewer. The crossed transmission of the images results in a stabilisation in the X and Y axis. This allows three-dimensional vision in colour via a colour television receiver with a picture tube or a projection device.

Title: Scraper traversing bridge for clarification plants
Inventor: KUPCZIK GUENTER DIPL ING
IPC: B01D21/04
Filed: 1984-02-15
Abstract: A scraper traversing bridge with a large span for clarification plants, having wheels arranged at the sides and scraping plates arranged in articulated fashion across the width of the scraper traversing bridge has a drive for the wheels in which an absolutely uniform torque for the traversing movement is provided for at least coaxial wheels (35, 36 and 37, 38 respectively). A driving torque which changes in the case of wheel slip is used as the setpoint value of a control system for driving torques of wheels included in the drive train and a corresponding torque of equal magnitude can be transmitted to the said wheels. At least coaxial wheels (35, 36 and 37, 38 respectively) are connected via a compensating control arrangement (45, 46). In this arrangement, the drives for each axle are monitored as regards driving power and speed of rotation and the associated drive shafts are adapted to one another to give a corresponding applied driving power by means of a compensating control arrangement (52) if the drive applied to the other drive shaft changes. <IMAGE>

Patent DE-3407453-A1 (DE)
Title: Heat pump with multiple utilisation
Inventor: DIETRICH HANS-JUERGEN
IPC: F24D11/02
Filed: 1984-02-29
Abstract: The heat pump can be used simultaneously for domestic water heating and for room heating by means of a combination accumulator. The primary energy can come e.g. from the air, the earth, from water or another heat source. In this connection, the energy types available can be used individually, in part or all together. By multi-step switching (2 different compressors), good adaptation to the respective heat requirement can be achieved. The conventional circulating pump between storage accumulator and heat pump is omitted. By connecting a small compressor (power consumption below the free limit of the energy supply companies), the storage accumulator can be significantly reduced or omitted entirely. With the abovementioned installation, a possibility is afforded of installing a heating installation in any one-family or two-family house, which works independently of fossil fuels and considerably more economically than a conventional heating installation operated with oil or other fuels.

Title: Drive system for changing the planar position of machines and devices as desired
Inventor: WERDAN KURT DIPL ING
IPC: B60K7/00
Filed: 1984-05-08
Abstract: The invention relates to a drive system for running gear which permits the machines or devices mounted thereon to change their planar position as desired (move in all directions, turn about the vertical axis, change their direction without turning), in particular for transport devices and industrial robots etc. In drive systems which are customary today usually having wheels or rollers arranged in parallel, movement facilities of this kind can only be achieved with a large degree of outlay. By means of four polydirectional rollers which are arranged in a criss-cross fashion and are driven individually in their wheel-hub axis, all the movements in the plane can be easily achieved when the drive motors are appropriately actuated (forwards, rearwards, stop).
