Title: Antibiotic intermediate streptamine prodn. - by reacting benzene trioxide with hydrazine and phthalic anhydride, hydrolysing, and reducing
Inventor: KOENIG HORST DR
IPC: C07D491/18
Filed: 1975-08-11
Abstract: In a new process for the prepn. of streptamine from the epoxy-hydrazine cpd. obtd. by reaction of cis-benzene trioxide with N2H4, the epoxy-hydrazine cpd. is reacted with phthalic anhydride to give an azine dione cpd.; the epoxide ring of this cpd. is opened in the presence of an oxy-acid; the phthalic acid residue is removed by means of caustic alkali or N2H4; and the resulting cpd. is catalytically reduced to streptamine. Streptamine, and streptidine which can be obtd. from it, is an antibiotic component and can be used e.g. in the synthesis of dihydrostreptomycin. Streptoamine can also be added to the nutrient media of antibiotic-forming micro-organisms. Simple process giving high yields of streptamine without the need for isolation of intermediates. The presence of the azine dione gp. is responsible for the stereospecific course of the ring-opening of the epoxide intermediate. In an example, streptamine sulphate is prepd. from cisbenzene trioxide via DL-1,2-anhydro-4,6-biimino-4,6-dideoxy-myoinositol, DL-1,2-anhydro-4,6-dideoxy-4,6- N,N'-(1,2,3,4-tetrahydro-1,4-diox- o)phthalazino -myoinositol and 1,3-dideoxy-1,3- N,N'-(1,2,3,4-tetrahydro-1,4-dioxo)phthalazino -- scyllo-inositol.

Patent DE-2602039-A1 (DE)
Title: Locking arrangement for toilet flushing chain - has trap ring to provide two different quantities of flushing water
Inventor: UFER WALTER
IPC: E03D1/14
Filed: 1976-01-21
Abstract: The locking arrangement is used for clamping the actuating rope of the high level flushing tank. The clamping arrangement makes it possible to dispense optionally the usual large quantity of water or alternatively a smaller quantity of water. When the actuating rope is pulled vertically down by the handle (4) then the flushing is carried out as normally. A sideways pull of the handle guides the rope to the inner edge of the holder (3) so that the shoulder contacts the ring of the holder and the pulling distance reduced in this manner results in a smaller opening of the outlet valve and hence less water is delivered for flushing.

Title: Universal joint for automobile propeller shaft - uses O:ring to centralise shaft in supporting sleeve
Inventor: MATYL FRANZ ING GRAD
IPC: F16D3/16
Filed: 1976-04-24
Abstract: The shaft (5) forms part of one half of the universal joint of an automobile propeller shaft. The shaft (5) is mounted in the sleeve (7) and in order to avoid dynamic unbalance the clearance (a) must be kept constant when the shaft is rotating. To avoid the need for fine tolerances, the shaft (5) is provided with a groove (9) for the O-ring (8). The elasticity of the O-ring (8) keeps the shaft (5) concentric with the sleeve (6) and thus minimises dynamic unbalance even with a considerable radial gap (a). The cost of manufacture can thus be reduced since it is not necessary to maintain the dimensions of the shaft (5) and sleeve (6) to very close limits.
