Patent DE-4110719-A1 (DE)
Title: Bus system operation method - using token passing between connected terminals and monitoring clock signal generated by terminal responsible for bus access allocation, with take over by another terminal if clock signal fails
Inventor: POLLY EDGAR DIPL ING
IPC: G06F13/37
Filed: 1991-04-03
Abstract: The method operates a bus system (2) with connected terminals (3-6) having access using the token passing principle involves controlling allocation of the bus to a terminal with a clock signal fed to all terminals. The clock signal is generated by one terminal responsible for the allocation of access. Each terminal contains stored information on the sequence of terminal bus accesses. The terminal monitors the clock signal. If it fails, the terminal decides which terminal takes over the allocation of access and hence the generation of the clock signal. ADVANTAGE - Enables all terminals remaining in operation after failure of one terminal to continue to communicate via bus system.

Title: Removal of dirt from motor car bodywork - involves directing jets of air onto bodywork as it is rotated
Inventor: NAKAMURA FUMITO
IPC: B60S3/04
Filed: 1991-08-23

Title: Grid beam assembly - has armouring of number of wear strips formed into stack to increase the working life
Inventor: DIETSCHE HORST DIPL ING
IPC: B32B15/01
Filed: 1992-10-06
Abstract: The grid beam, with a beam body (16) of tough steel, has a wear-resistant armouring (22, 24) as a number of overlaid wear strips (26). They are each fitted with an underlay of tough steel covered by a wear layer. The overlaid wear strips (26) form a stack, with the layers bonded to each other, with aligned openings (28, 30, 32) in each layer for locking rods (34, 36, 38) which are welded to the beam body (16). A holding ring is fitted into the openings (28, 30, 32) in each wear strip (26) layer, welded in place as a support for the locking rods (34, 36, 38) passing through. The holding rings have a radial sliding movement against support rings keyed to the locking rods (34, 36, 38). The stack of wear strips (26) is covered by a wear-resistant layer, with a buffer layer between it and the stack as a tough welded layer. The length of the wear strips (26) increases from the free edge of the stack to the beam body (16) and the ends are secured by a head section (42, 44) with a matching step shape, to be held firmly against the beam body (16). The armouring (22, 24) is in a keyed fit in recesses (18, 20) in the beam body (16) to project slightly over the body (16). USE/ADVANTAGE - The grid beam assembly is used to break down sintered clumps of mixtures of ore and coke, such as in steelworks, where prongs pass through the grid to break down the material where it is at temps. of 1000 deg.C and it has a highly abrasive nature.

Abstract: PCT No. PCT/DE94/00029 Sec. 371 Date Sep. 5, 1995 Sec. 102(e) Date Sep. 5, 1995 PCT Filed Jan. 14, 1994 PCT Pub. No. WO94/17107 PCT Pub. Date Aug. 4, 1994The present invention provides a process for the manufacture of a product essentially containing amylose from vegetable materials, in particular from peas. To this end, the flour is mixed with an alkaline decomposing agent, and then a separation into a liquid protein phase and a solid phase containing polysaccharide is performed. The solid phase is then re-suspended and subjected to several sifting steps, followed by at least one washing step and subsequently a drying step. From such polysaccharide material, in particular from amylose, any kind of moisture-resistent, flexible, and in particular biodegradable articles can be produced by means of conventional plastics technologies, in particular the injection molding technique. A particular advantage of the present invention resides in the fact that the thermoplastic polysaccharide material, which is produced from renewable raw materials, can also be processed into sheets which in turn can then be worked with conventional plastics techniques.
