Filed: 1976-07-29
Abstract: In the prodn. of ornithine in the form of its salts, a 1-alkoxycarbonyl-2-alkoxypyrrolidine of formula (I): (where R1 is 1-4C alkoxy and R2 is 1-4C alkyl) is reacted with at least equimolar amts. of HCN and NH3 and opt. CO2 in aq. or aq. alcoholic reaction medium at ca 70-150 degrees C (pref. ca 90-120 degrees C) under substantially autogenic pressure, and the reaction prod. (an aminonitrile when NH3/HCN is used, or a hydantoin when NH3/HCN/CO2 is used) is hydrolysed in a conventional manner. In an example, 79.5g (I, R1=OCH3, R2=CH3), 79g NH3-HCO3 and 16g HCN in 300 ml water are autoclaved 8 hrs. at 100 degrees to give 69g 5-(3-methoxycarbonylpropyl)hydantoin. Hydrolysis of this with conc. HCl at 160 degrees gives ornithine hydrochloride in 89.6% yield.

Title: Safety valve for motor vehicle fuel tanks - incorporates inertia switch which closes valve in event of crash exceeding preset force
Inventor: SCHILLAK MANFRED
IPC: B60K15/01
Filed: 1977-06-18
Abstract: The safety valve is for motor vehicle fuel tanks. The safety valve is located in the pipe leading from the tank towards the outside which is normally in the open position. In the event of a crash the valve closes automatically through the action of an inertia switch (2) which acts on a shock or blow of predetermined force and which controls the action of the valve. The valve is subject to a permanent closing force exerted by spring tension and the inertia switch (2) includes an opening force opposing the former and exceeding it in size. Any shock or blow exceeding the predetermined value displaces the opening force by changing its direction, permitting the closing force to operate.

Patent DE-2742317-A1 (DE)
Inventor: HAUENSTEIN GUENTHER ING GRAD
IPC: G07D3/14
Filed: 1977-09-20
Abstract: Coin-distributing apparatus for sorting coins (8) along a horizontal sorting channel (2). The coins (8) are transported, clamped between a pivotably suspended endless band (6), arranged, together with its drive (12), on a board (9), and a guide plate (1), and are sensed on their circumference, in relation to a guide rule (16), by measuring points (43) actuating limit switches (46). Each actuated limit switch (46, 51) triggers a stop device (13, 26, 30) of the endless band (6) and energises an electromagnet (31) for pivoting away the endless band (6) and for discharging the coin (8) from the guide rule (16) into sorting channels assigned to the measuring points. A higher transverse running speed can be achieved by means of the conveyor band (6). Each type of coin is assigned a good and a bad collecting channel and a measuring roller (52) checking the thickness of the coins (8). The position of the centre of gravity of the board (9) relative to the rotary bearing (15), on which it is suspended, determines the pressing force of the endless band (6) on the coin (8). There serves as a stop device (13) for the endless band (6) a one-way coupling (27) seated on the drive shaft (24) of the drive motor (12) and having a pivoting arm (26) which, during the reversal of the running direction of the drive motor (12) by means of the limit switches (46, 51), switches off the drive motor (12) by means of a further limit switch (30). <IMAGE>

Filed: 1978-05-30
Abstract: A liq. dyestuff concentrate is added continuously and with uniform distribution over the exhaust phase, to a dyebath pre-heated to the dyeing temp. and contg. no dyestuff. In this process, the dyestuff concn. in the dyebath remains slightly above the equilibrium concn. The novelty is that cellulose fibres can be dyed, their affinity to substantive dyes being increased by chemical treatment, (the liq. dyestuff concentrate is introduced into the dyebath at a position before the jet). For polyester-rayon mixtures also, uniform dyeings are obtd.

Title: Magnetic key for lock with magnetic rotors - has polygonal inserts magnetised separately before insertion into key or rotor
Inventor: REUMANN FRANZ
IPC: E05B47/00
Filed: 1978-07-13
Abstract: The key and rotor magnets are made in the form of separate inserts individually magnetised to prevent interaction on assembly. Alternatively, one magnetic component can be inserted into the key or a rotor and this component is subsequently magnetised. A second component is fastened after that and this is once again magnetised until all the magnetic components are fitted into the key or rotor. In another method the components are magnetised individually and separately from the key or rotor and then inserted. These magnetic components can be noncircular and have elliptical pear-shaped or polygonal pref. octagonal shape in order to avoid angular errors on insertion.
