Patent DE-19543184-A1 (DE)
Title: Device for mechanical polishing of conical surfaces e.g. optical glass
IPC: B24B13/06
Filed: 1995-11-20
Abstract: The device has conical polishing tool (20) with its base radius (r) smaller than the radius of the conical surface of the workpiece (7). The tool rotates at an adjustable speed whilst oscillating from side to side in a direction (X) parallel to the straight line generated by the sides of workpiece profile.  The speed of the oscillation is determined by the existing shape of the workpiece surface at any point in time. There is always relative movement between the tool and the workpiece even at the centre. The shape of the workpiece can be altered by control of tool movement during the polishing process.
Patent DE-19544094-A1 (DE)
Inventor: FERRIERE PHILIPPE
IPC: H04N7/26
Filed: 1995-11-27
Abstract: A method is disclosed of storing and progressively transferring a still image so that it can be conveniently previewed during the transfer and so that a user can terminate the transfer at an early stage if the image turns out to be undesirable. The method includes transforming the image into a plurality of decomposition levels 12, 14 using a discrete wavelet transform. Each decomposition level comprises a plurality of subimages, LL1, LH1, HL1, HH1, which allow reconstruction of an image representation of the still image. The decomposition levels are transmitted beginning with a base decomposition level providing a low level of image resolution and then proceeding with decomposition levels providing increasingly higher levels of image resolution. Within each decomposition level, rows of the various subimages are arranged or interlaced together in contiguous blocks, so that all data for a single row, at a single decomposition level, is transmitted together. At the receiving end of the transfer, the row blocks are reconstructed and displayed as they are received. The invention enables the initial display of a low resolution image which is gradually updated and sharpened, on a row-by-row basis, until a desired high resolution is achieved. The user may terminate the transfer at any point. <IMAGE>

Patent DE-19615048-A1 (DE)
Title: Semi-automatic self-monitoring fault-current circuit-breaker e.g. for main current conducting lines
Inventor: BERTHOLD RAINER DIPL PHYS
IPC: H02H3/05
Filed: 1996-04-17
Abstract: The switch has main current contacts which form a disconnection point in the mains lines. It also has a total current transformer through which the mains lines are passed through as a primary winding. The output signal of the secondary winding is transmitted to a relay on the basis of a faulty current. The relay opens the contact.  The switch also has a test current circuit with a test contact point. When this is closed a faulty current is simulated. When a connected load is first switched on and/or off it continually switches off using an electric device and is functional after it is first switched back on again. When the switch fails or the main current contacts are switched off with a non-simulated real faulty current, the main current lines are broken or interrupted using a diverse and/or redundant auxiliary cut off point and cannot be closed again.
