Patent DE-4120706-A1 (DE)
Inventor: RUDER ARIE
IPC: B28B1/26
Filed: 1991-06-22
Abstract: The invention relates to a process for producing dense sintered articles from metal or ceramic materials. A flowable casting composition consisting of the pulverised material, a binder and a solvent is poured into a predetermined mould and subsequently dried. The binder is removed from the green compact thus formed and the latter is sintered. The proportion of binder in the casting composition should be minimised. Expediently, the mould is vibrated during the casting. Heating control during drying with simultaneous application of a vacuum is advantageous. Multi-layered articles can also be produced by suitable application of the process.

Title: Open=end spinning rotor cleaning - has multiphase operation to shift alignment of compressed air to loosen debris and removal from the rotor assembly
Inventor: LOVAS KURT
IPC: D01H4/24
Filed: 1991-09-23
Abstract: A compressed airstream is directed into an open-end spinning rotor assembly for cleaning, with initial application against the fibre collection gutter and then, in a second direction, at the space between the open edge of the spinning rotor and the rotor cover. Pref. in the second direction, the compressed air stream is directed from the fibre collection gutter against the open edge of the spinning rotor where there is a suction stream. During the second phase, the gap between the open edge of the spinning rotor and the rotor cover is increased, and the compressed air stream is brought towards the suction air flow. Both cleaning phases are repeated once or more frequently. A further cleaning phase can be used, after the first or second phases, where the gap between the open edge of the spinning rotor is wholly exposed. In the first cleaning phase, fibre material and debris is loosened and then detached in the second phase for removal in a third phase. In the first or third phase a compressed air stream is generated against the base, towards the suction, across the fibre ring. After at least two cleaning phases, while the spinning rotor is braked, the rotor is momentarily operated and then braked again while the spinning rotor is braked, the rotor is momentarily operated and then braked again while the air stream is varied longitudinally against the rotor. The suction air stream is directed against the force of gravity. During the first cleaning phase, fibres are temporarily fed to the spinning rotor. ADVANTAGE - The action gives a highly effective cleaning action, with high working efficiency to allow manual operation of an automatic cleaning assembly. in

Patent DE-4213051-A1 (DE)
Inventor: KIMMIG LUDWIG DIPL ING
IPC: G01N21/3504
Filed: 1992-04-21
Abstract: In order to measure the nitric oxide concentration in a measuring gas containing water vapour by means of NDIR gas analysis, the measuring gas, possibly after water vapour has been partially removed, a zero gas by means of which the zero point is determined and a test gas which contains a known concentration of nitric oxide and with which the extent of the measurement effect is determined, are taken via a humidifier so that all three gases have the same water vapour concentration. After the zero point and the measuring effect have been determined, the interfering effect of the water vapour on the measurement can be eliminated by finding the difference and the use of a correcting calculation. The invention is used in the measurement of nitric oxide in exhaust gases.

Patent DE-4216684-A1 (DE)
Inventor: BROSS GUENTER DIPL ING
IPC: H02H9/04
Filed: 1992-05-21
Abstract: A current mirror with at least one pnp-transistor (10, 11) has an emitter (14, 15) to which is applied a positive voltage. Both collectors are designed as partial collectors (16, 17 or 18, 19) of a collector that surrounds the emitter (14, 15) substantially as a ring. The first partial collector (16, 18) and the base (20) are connected to a source of reference current (21) and the second partial collector (17, 19) is linked to a connection (22) of the current source that needs to be protected against overvoltage. In the case of an overvoltage at the connection (22), the emitter is formed by the second partial collector (17, 19) linked to said connection (22). In case of overvoltage, therefore, the absorbed current can rise only up to a limit value (Iü) which is in a topology-conditioned relation to the reference current (Iref) of the mirror. An effective protection against overvoltages is thus ensured.
