Patent DE-19540122-A1 (DE)
Inventor: RICHARDS DAVID R
IPC: H05K3/18
Filed: 1995-10-27
Abstract: A method for decreasing the initiation time of an electroless bath involves exposing a plurality of small metal oxide particles contained in a resin defining a surface. The surface is then treated with reducing solution which results in catalytic islands forming around the metal oxide particles and is then treated with a noble metal salt solution of a concentration less than 0.1 molar. This results in a fine layer of noble metal on top of the catalytic islands and protects the islands from oxidation. The surface is the placed in an electroless bath. It has been found that the initiation time in the electroless bath has been reduced from fifteen minutes to less than two minutes.

Title: Obtaining graphical display of reduced-view spectrometer sections on computer system
Inventor: BARBER LUTHER L
IPC: G06F3/048
Filed: 1995-10-27
Abstract: The graphical display method involves a computer which uses a windows program, with which a direct comparison can be made between the spectra through simultaneous display on the VDU, whether alongside or by superimposition. By comparing selected data points on the display against relative indicators a difference spectrum showing differences between the test spectrum and the reference can be produced. Sections of the spectrum can be analysed in greater detail with on screen wavelength measurement. A database of spectrum analyses can be built up and a spectral library including name and index information created for subsequent use. The system uses reduction and enlargement of the spectra in a radial window and point-and-click graphic icons.

Title: Coupling that can be switched between automatic and manual drive
Inventor: HAUSY WERNER
IPC: B64C13/00
Filed: 1995-12-18
Abstract: The coupling has, on the driven shaft (10), multiple grooves (11) distributed round its periphery to accept balls (1) that click into place in the grooves and lock the two parts of the coupling to transmit motion. An internal rotating ring (20) on the driven shaft carries the balls in chambers round its edge so they can slide radially. A switching ring (30) on the internal rotating ring can be displaced between two angular positions. It has one or more internal grooves and also has grooves distributed round its outer periphery to receive exterior balls carried in an outer ring. The coupling mode depends on the angular position of the switching ring.

Patent DE-19609572-A1 (DE)
Title: Car dismantling via connections into single parts
Inventor: BOCK DIETER
IPC: B62D65/00
Filed: 1996-03-12
Abstract: The connections (26) are parted by a high-energy water jet (12), the cars (17) so driven and swivelled so as to line up the connections over the water basin (4,5) before the jet-assisted parting action. The connections lie horizontal over the basin, and the jet is directed vertically upwards. Identical car types are parted at their connections in the same sequence each time to yield their single parts. The parting action stems from water source (1) to cutting head (2) where the pressurised source water issues from the head (2) nozzle to form a high-energy jet (12) which strikes the absorber (3) on the far side of the car connection (26). The cutting action is assisted by a manipulator (19-25) used to drive and swivel the car as appropriate, using basin (3) as energy absorber. The head nozzle is directed downwards from the swing-arm fitted head. Head and manipulators submit to a control system ensuring any one car type connections are parted in the same order.

Patent DE-19651101-A1 (DE)
Inventor: LIPKOWITSCH NIKOLAI
IPC: G07D7/12
Filed: 1996-12-09
Abstract: The device according to the invention has an illumination system which illuminates sheets with pulsed exciting light. During the light phase of the pulsed exciting light and during the dark phase of the pulsed exciting light respectively, a sensor detects an intensity of the light emitted from the sheets. An intensity of the fluorescently emitted lights and an intensity of the phosphorescently emitted lights are deduced in an evaluation device from the intensities detected in the light phase and dark phase of the pulsed exciting lights. In order to guarantee a longest possible pre-illumination with high intensity, the sensor detects the intensities of the emitted light preferably within and in transport direction towards the end of the area of the sheets illuminated by the illumination system. In addition, so large an illuminated area of the sheets is chosen, that it has many times the desired resolution.
