Patent DE-3805358-A1 (DE)
Title: Saw-band guide
Inventor: BOBAN FRANZ
IPC: B23D55/08
Filed: 1988-02-20
Abstract: The invention relates to a preferred saw-band guide for guiding saw bands on horizontal and vertical bandsaw machines having an endless saw band, which is laid around holding and driving wheels, in order to hold and guide the saw band in the area of the cutting zone. The special requirements to be met by the invention consisted in developing a universal saw-band guide which can be used in front of and behind the workpiece in all bandsaw machines, meets the most stringent requirements as regards quality and - without the use of spare parts - guarantees virtually unlimited running time of the important guide elements. This is achieved by all guide elements having a ceramic or carbide ring and in addition by all guide elements being interchangeable. The guide elements, which consist of only a few parts and are therefore simple to manufacture, are adjustable in all three axes, which permits really accurate fixing of the saw band, despite the use of saw bands of different height or width, with simple manipulation.

Inventor: WOELKY OTTO WERNER
IPC: B63H1/36
Filed: 1989-01-27
Abstract: A propulsion system operated by physical effort for watercraft, in particular for rowing boats of various design, such as, for example, a catamaran. This newly developed rowing system, consisting of a slide rowing plate, a slide rowing lever, a sliding-seat slide and tiller, has no oars as still customary today but is propelled by physical effort via a propulsion system (of various design), as a result of which the hull moves forward by the rowing blades skimming back or by the opening and closing of valve flaps or by the flaps which consist of several parts and open and close, while the water is displaced, in the range of view of the rower. In the process, the requisite stroke of the rowing systems is increased by the sliding-seat slide in order to obtain effective power outputs. This novel boat system has various boat and propulsion systems which can be used alternatively. Equipment and shapes which are suitable for sporting and physical adaptations are used in particular for physical training. These systems enable lakes, rivers, especially narrow rivers, and coastal waters to be navigated and can be used with several persons.

Patent DE-3928175-A1 (DE)
Inventor: APITZ SIEGFRIED
IPC: H04N7/087
Filed: 1989-08-25
Abstract: The device described updates text pages in predetermined time intervals. These pages can be accessed at any time. The program locations are associated with page designations, that is to say in each case one program designation with page number. As a result, pages can also be accessed which are transmitted in a program which does not correspond to the active program. To program in such page designations, a program designation/page designation table is of assistance. If paging is to be carried out between pages, this is done by shifting a cursor into margin areas of a text page. All programs within the same time horizon can be paged through. From the pages, transmissions can be selected for recording. Transmission dates are transferred into a transmission/storage device. In this device, a marking is set as soon as a recording has been concluded. Either only marked or only unmarked transmissions can be optionally displayed. If the transmission dates are stored in relation to cassettes, the possibility for cassette management is given. To make the recordings as complete as possible, the device has the capability of automatically finding titles in text pages and entering these titles in the transmission/storage device.
