Title: DC circuit commutator unit - has contactless commutator to provide linear and exponential characteristic to minimise voltage variations on supply lines
Inventor: VELIN ANDREI VENIAMINOVITSCH
IPC: H03K17/284
Filed: 1979-04-12
Abstract: The contactless commutator arrangement for d.c. circuit applications operates to a linear or exponential low to minimise the voltage variations on the supply lines. The d.c. source (4) is coupled to a load (7) with connection (2, 3) to a transistor switch (1). The control electrode (8) is connected to a changeover contact (9) with a control unit (11). Two d.c. generators (13, 14) of opposite polarity are connected to the contacts. The stabilising generators produce a current over a capacitor (12) that results in a linear change in the load circuit current. Alternatively the generator function may be provided by d.c. sources with coupled resistors to give an exponential characteristic.

Title: Improved operation of multi-bed adsorption purifier - by adjusting flow rate through bed to previous performance
Inventor: DROOP FRITZ DR
IPC: C10K1/32
Filed: 1980-02-23
Abstract: In a multi-bed adsorption installation, impurities are removed from a process stream in a series of beds operating in staggered pressure cycles, the let-down gas from a bed under regeneration being used to pressurise other, recently-purged beds. In an improved method of operation, the amt. of process gas passed through each bed when in the adsorption phase is decided by the amt. of impurities present in the purge gas in the preceding desorption phase, the more the impurities, the less the process gas treated subsequently. The process is described by reference to the removal of CO, CO2,N2, and CH4 from H2 from steam reforming. Output of plant is increased. The situation is avoided where a fall-off in effectiveness of adsorption in one bed is propagated through the assembly of beds, and the disturbance to prod. quality is prolonged.
Patent DE-3014084-A1 (DE)
Inventor: SCHNEIDER RUDOLF
IPC: B23H7/10
Filed: 1980-04-12
Abstract: The threading method works with a directed liquid jet (34), inside which the initial section (32) of an electrode wire (30) put in comparatively slowly is guided through the working space with a correspondingly brisk relative movement and therefore corresponding drive force. This relatively high drive force results in a certain longitudinal tensioning of the wire and thus keeps it straight during the threading operation. The liquid jet therefore continues throughout the threading operation and accordingly is free of disturbance during the intermittent jet build-up. The device used accordingly has a nozzle connected to a source of pressure liquid and directed into the working space, the electrode wire in the nozzle outlet area being arranged coaxially to the nozzle openings and being held coaxially in the continuous liquid jet. <IMAGE>

Title: Desulphurisation of boiler stack gases - by injection of lime into heat exchanger tubes and spreading it by moving brushes
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/60
Filed: 1980-10-24
Abstract: In a process for desulphurising the combustion gases from a boiler and simultaneously improving its efficiency, brushes are moved to and fro or rotated in the heat exchanger tubes while an SO2-absorbent, e.g. powdered hydrated lime, is injected upstream. The brushes remove incrustations (so improving heat transfer) and spread out the lime for better absorption efficiency. The used lime is trapped downstream in a separator, and the off-gas can be discharged from a low stack. Used for e.g. oil-fired boilers. Because of alkaline conditions on the tube surfaces, the dew point can be traversed safely and corrosion is reduced.

Title: Cassette for typewriter ribbon - has rows of holes in base with bottoms covered by elastic membrane to reduce noise
Inventor: KEITER ALFRED
IPC: B41J29/10
Filed: 1980-12-13
Abstract: The typewriter has the ribbon mounted on a spool (29) inside a casseteecassette. The ribbon is unwound off this spool and wound on to a second spool, as it is being used. The base (49) of the cassette has rows of holes (39) which form a sound damping barrier to reduce the noise from the typewriter.
