Title: Method and machine for cutting boards for ploughed and tongued coverings
Inventor: ANDERSSON BENGT AXEL
IPC: B27F1/06
Filed: 1982-04-17
Abstract: Method for cutting boards (10) for ploughed and tongued coverings, in which method the two edges of the boards are first worked in a first step 1A) in order to obtain pure wood, the correct dimensions and the correct profile of the boards. Then, in a second step 1B), a groove (18) is made in one edge of the boards by pre-cutting with the aid of roughing blades and finish-cutting, and a bevel (19) is made in the opposite edge of the boards likewise by pre-cutting with the aid of roughing blades and finish-cutting. In a third step 1D), 1E), the cut bevel (19) is smoothed, and a rebate (21) is cut in the last-mentioned edge to form the tongue (36). The machine for carrying out this method comprises separate stations for the three production steps and means which guide the boards (10) for engagement with the cutting tools (11, 12, 16, 17, 35, 20) and cause the cutting tools (16, 17) of the second step 1B) to rotate in the feed direction of the boards (10) and the remaining cutting tools (11, 12, 35, 20) to rotate counter to the feed direction of the boards (10). <IMAGE>

Title: Device for the intermittent rotation of valves leading into the cylinder space of an internal combustion engine
Inventor: WOLF GOTTLIEB
IPC: F01L1/32
Filed: 1982-07-09
Abstract: The angular momentum for the intermittent rotation of a valve (8) in the cylinder cover (3) of an internal combustion engine is produced by a drive (20) which is independent of the instantaneous operating condition of the internal combustion engine. In this way, it is ensured that the intensity of the angular momentum, which is retarded by friction of the closing valve body (8) on the valve seat (5), is sufficient even in the case of partial load to achieve removal of deposits adhering to the valve body (8). <IMAGE>
Patent DE-3233865-A1 (DE)
Title: Ship/tipping elevator
Inventor: ANKER FRANZ
IPC: E02C3/00
Filed: 1982-02-25
Abstract: The elevator described is intended to overcome differences between the levels of waterways in a simple manner without water losses - as is normal, for example, in lock operation. Even the largest cataracts can be bridged quite simply in this way. A travelling tank into which the ship to be lifted is steered is driven not by tackle lines but on a multi-rail trackway in one-man operation - with the ship floating in the water - between upstream and downstream water over the crest of the dam. When the ship arrives at the top or bottom, the drop door opens and the ship can move out within a few minutes. The construction costs for this installation are exceptionally favourable, since neither underground structures nor structures above the surface are necessary. Nor are any electronic systems required, since the operators can clearly see the entire installation from the control station. Inspections or repairs, which would probably hardly occur, can all be carried out above ground and consequently particularly inexpensively. A minimum of personnel is required in order to operate the installation.

Title: Pre-emphasised electro-acoustic transducer system
Inventor: KOPPEL WOLFGANG
IPC: H04R3/04
Filed: 1983-07-15
Abstract: For broadband, transient-free conversion of any given audio signal into sound, this signal is modified in a computing circuit in such a way that the distortions occurring due to mass inertia and elasticity in a specific dynamic loudspeaker are cancelled. The loudspeaker is controlled from a power amplifier with a current output and has a diaphragm of inherently rigid design, only part of which is used for sound radiation. This part is particularly rigid and is intended to move in a piston-like manner. The mechanical dimensions of this required movement in the loudspeaker are simulated in the computing circuit as electric quantities. As a result, the instantaneous speed of the diaphragm is proportional to the audio signal. The integrable computing circuit contains, inter alia, differentiation, integration and summing components. The transducer system is provided by one-way loudspeakers, high-quality compact loudspeakers and qualified stereo reproduction.
