Filed: 1980-07-03
Abstract: In a process for reaction of powdered or liq.hydrocarbon- contg. materials (I) with water vapour or liq. (II) and opt. 02 to a mixt. contg. CO and H2, some or all of the heat required comes from mixing with a heat carrier fluid (III). (III) may be a preheated mixt. of a low-value fuel gas and 02. (I) and (II) enter the top of a vertical cylindrical reactor via an axial inlet, while (III) enters tangentially at the same level and acquires a downward spinning motion. Any slag formed gathers in a heated channel round the reactor base, and is discharged as liq. for processing. The process is useful for the gasification of coal, hydrogenation, residues, etc. Energy supplied as (III) can be cheaper than as (I) plus 02, as in prior art. The appts . is more compact and heat loss is reduced. Ash-rich (I) may be used.

Patent DE-3045125-A1 (DE)
Title: Rotational distance transducer for direct compensation - relates to thermal, elastic errors, and is driven via spindle in captive nut
Inventor: JAKOB LUDWIG ING GRAD
IPC: G01D3/028
Filed: 1980-11-29
Abstract: A distance transducer for compensation of thermal, elastic or other errors, e.g. in numerically controlled machine tools, uses a rotational distance measurement system compatible with the machine or its controller. It produces a compensation signal directly from the error at low cost. For a distance error introduced axially into a spindle (1), the spindle is caused to rotate in a fixed nut (2) and to turn the shaft of a rotational distance transducer (7). If an axial motion is imparted to a nut which cannot rotate it causes a spindle to turn and this motion is transferred to the shaft of a rotational transducer via a coupling. The spindle pitch and resolution are chosen to ensure that the transducer signal shape and resolution are equivalent to those of the primary measurement system.
Patent DE-3103249-A1 (DE)
Title: Circuit arrangement for telephone sets with a transistorised microphone which is de-activated during subscriber dialling
Inventor: DROSSEL MICHAEL ING GRAD
IPC: H04M1/31
Filed: 1981-01-31
Abstract: In using a transistorised microphone in telephone sets which is de-activated during dialling and is connected to the speech wires only after the dialling, the difficulty arises that, due to the different electronic components of a microphone of this type, a stable voltage condition of the type which prevails when a call is in progress is reached by this microphone only after a delay. At the beginning of the connection to the speech wires, the microphone concerned is still in a high-impedance state, which leads to an undesirable temporary excess voltage between the speech wires. To reduce this excess voltage or render it harmless, the invention proposes that the reversing pulse for the bistable changeover relay which initiates the connection of the microphone to the speech wires by de-energising this relay also acts on the electronic pulse contact in such a way that the latter transfers from the conductive to the blocked condition only when a stable voltage state has been established in the transistorised microphone, so that, up to this time in parallel with the temporarily higher-impedance microphone, a low-impedance current path is produced which effectively suppresses the aforementioned voltage increase.
Patent DE-3105095-A1 (DE)
Title: Method and device for removing a sticky sheet
Inventor: TAKAHASHI YASUHIRO
IPC: B41L13/14
Filed: 1981-02-12
Abstract: A sticky sheet which is to be removed is transported in a first direction, parallel to its upper side, in such a way that its leading edge strikes against a stop device. The sticky sheet is then transported further in the first direction and folded in a second direction, which is essentially perpendicular to the first direction, to form a plurality of layers which strike against the stop device, said layers resting on a flat support device which extends from the lower region of the stop device in a direction counter to the first direction. The layers of the folded sticky sheet lying one above the other are then conveyed in a third direction which is essentially perpendicular to the first direction and to the second direction, during which time said layers are compressed so that the sheet is removed in the form of a relatively thick and narrow strip consisting of a plurality of layers lying one above the other and adhering to one another due to their stickiness. The device for removing a sticky sheet operates in the manner described above.

Patent DE-3108566-A1 (DE)
Title: Pendulum motor for clocks
Inventor: MERKLE PAUL
IPC: G04C3/027
Filed: 1981-03-06
Abstract: The pendulum motor according to the subject matter of the invention for wall clocks is not controlled by an electronic time standard as in standard electronic clocks, but by the angle of deflection of the electromagnet pendulum. In the case of an increased angle of deflection of the pendulum, the corresponding end (N) of the arcuate permanent magnet (11) penetrates the control coil (3) at a higher speed than normally. This increased speed of penetration generates in the control coil (3) a higher voltage peak which also comes to act in an amplified way at the transistor (44), which thus discharges more current into the zero potential in the case of a higher control current voltage than in the case of a standard control current voltage. As a result of the reduced drive voltage at the transistor (45), the resistance thereof is larger than in the case of a standard angle of deflection of the pendulum, and thus a lower current flows in the load circuit of the operating coil (2) in the case of an increased angle of deflection of the pendulum than in the case of a standard angle of deflection of the pendulum. <IMAGE>
