Title: Mobile crane with main boom and mast in adjustable guyed system
Inventor: KNECHT ALEXANDER DIPL ING
IPC: B66C23/36
Filed: 1996-10-07
Abstract: The adapters between head and foot ends of the necessarily short auxiliary boom (16) have the same or larger transverse dimensions as the main boom (4) and the maximum length of the auxiliary boom required for heavy loads is afforded by the fact that the increase in bearing load achieved by the main auxiliary booms together imparting the total strength of the structure is compensated for by the reduction in bearing load produced by the dead mass of the auxiliary boom (16). The struts (20) hinged to the main boom head and auxiliary boom foot are joined to one another by a length-adjustable anchoring guy, the bottom guy rigidly joined to the main boom (4) and the upper guy to the auxiliary (16). Typically the angle of the auxiliary to the main boom is controlled by adjusting the length of the guy arrangement (21,22).

Patent DE-19803488-A1 (DE)
Inventor: NATH GUENTHER DR
IPC: C08J7/04
Filed: 1998-01-29
Abstract: The invention relates to a method for producing surfaces on substrates made of polymeric hydrocarbons, especially made of polyethylene or polypropylene, which are at least partially fluorinated by pretreating them with fluorine gas. The polymeric hydrocarbons are subsequently coated with an amorphous perfluoropolymer dissolved in fluorinated liquids by means of dipcoating. After tempering, a chemically inert layer results which adheres well and which protects the substrate against aggressive chemical solvents. According to the same method, superficial partially fluorinated tubing made of polyethylene can be coated inside with a thin layer of an amorphous perfluoropolymer and said tubing can then be used as sheathing tubing for fluid light guides.

Title: Process for synchronising and/or data exchange for secure high access computer in multi computer system
Inventor: SCHMERBECK FRIEDRICH
IPC: G06F11/16
Filed: 1998-02-25
Abstract: The process has memory areas, e.g. dual port RAM, of an external coupling board assigned to parallel processor channels. Each memory cell identifies a synchronising and/or data exchange point, parallel in the channel. Each processor channel can read and write to its assigned memory location. The memory locations can only be read by non-assigned channels. Each channel knows the cell address which first reaches the point in its program section. A current event number and the data content of the event are written to the memory cell of the coupling board assigned by the cell address to the channel.  The channel cell of the memory location of the other channels are tested for an event of the same number. If they do not have the same number, the channel message is put in the buffer of the channel in a wait loop. If the other channels have reached the point an alert interrupt is sent to other channels. The cells of all the channels are read, compared and voted. The next program sections is started and or and alert is provided for a vote result
