Title: Internal-combustion engine operated on gaseous fuel
Inventor: KATZENBERGER ALBERT ING GRAD
IPC: F02M21/02
Filed: 1982-06-24
Abstract: In order to avoid the risk of explosion due to escaping gas in the case of internal-combustion engines which are operated on gaseous fuel, the gas line is provided with an automatically safely shutting-off valve which is dependent on the operating state of the internal-combustion engine and shuts off the gas supply to the engine when it is at a standstill or when there is a fault in the system. This shutting-off is performed as a function of the rotational movement of the internal-combustion engine and, if appropriate, also of other physical variables such as pressure or temperature, if they exceed a predetermined value at a relevant point of the system.
Patent DE-3224575-A1 (DE)
Title: Unitary light source
Inventor: HICKS JOHN M
IPC: H05B35/00
Filed: 1982-07-01
Abstract: Unitary light sources comprise a compact HID lamp and an associated starting and operating circuit which can be operated at domestically available AC potentials. The HID lamp is loaded by incandescent filament devices which also provide the majority of the light generated during the HID warming-up period and also after power interruptions. The ballast incandescent filament and the input connections of a full-wave rectifier are connected in series via the light source input connections, while the HID lamp is connected across the rectifier output. A low-impedance-path device and a high-voltage pulse generator, which comprises a high-voltage electrode that is operatively connected to the HID lamp, are connected across the rectifier input. Initially, the voltage which is generated across the rectifier input is relatively high and the pulse generator and the low-impedance-path device react thereto in that they generate high-voltage pulses and also produce a low impedance path in series with the ballast incandescent filament in order to make the incandescent filament glow brightly. The high-voltage pulses generated, which are supplied to the high-voltage electrode, ionise the atmosphere inside the HID bulb. Once the HID lamp has started, the voltage generated across the rectifier input is no longer adequate to energise the low-impedance-path devices and the pulse generator devices. While the HID lamp is warming up, the brightness of the incandescent lamp ballast devices is reduced. A lamp operation maintenance circuit, which comprises a DC source, is connected across the output connections of the rectifier in order to supply lamp operating power during periods of rectifier conduction minima and in order to supply DC power as a lamp starting aid when necessary.
Patent DE-3225827-A1 (DE)
Title: Steel frame formwork element and method for bracing it
Inventor: STEIDLE-SAILER MANFRED DIPL IN
IPC: E04G9/06
Filed: 1982-07-09
Abstract: In a steel frame formwork element composed of box profiles, passage holes into which protective sleeves are inserted are provided in opposite walls of the box profile. In the region of these protective sleeves, there is provided, between the two opposite walls, a bracing which prevents the box profiles from being compressed in the direction of the longitudinal axis of the sleeve and thus prevents the protective sleeve from being pushed out. The bracing can be effected by the protective sleeve itself, in that the latter is calculated with the necessary buckling strength and the front ends are preferably positively supported on the inside of the opposite walls in such a way that there is no danger of the sleeve being pushed out. Instead of this, additional spacers of various shapes can be arranged in the region of the protective sleeves between the opposite walls of the profile as a bracing.

Title: Process for continuously producing hydrocarbon oils from coal, heavy oils, tars and vacuum residues by pressure hydrogenation
Inventor: KUERTEN HERIBERT DR
IPC: C10G65/12
Filed: 1982-09-16
Abstract: The application relates to a process for continuously producing hydrocarbon oils from coal, heavy oils, tars and vacuum residues by pressure hydrocracking in three stages, ground coal with an oil mixture or heavy oils, tars and vacuum residues being pasted with finely disperse catalysts in the first stage, the resulting paste and hydrogen being heated and hydrogenated under pressure (liquid phase) and the gaseous reaction products being separated in hot separators from the liquid and solid reaction products and being passed in one or more reaction chambers over the hydrogenation catalysts arranged in the gas and being hydrogenated again (gas phase), the heat of the end products being transferred by heat exchange to the starting materials. Oils which have condensed out are separated into heavy boilers and light boilers in stripping columns under the system pressure with the aid of the process heat. All three stages, namely liquid phase, refining and hydrocracking, are carried out successively without let-down between the individual stages.

Inventor: KUISL MAX DR RER NAT
IPC: G01N27/414
Filed: 1982-10-05
Abstract: Ein Flüssigkristall-Sichtgerät soll derart beschaffen sein, daß es bei großem Informationsumfang einen raschen Informationswechsel unabhängig von der Umgebungstemperatur bei möglichst geringem schaltungstechnischen Zusatzaufwand für die Sichtgerät-Ansteuerung ermöglicht. Dafür wird ein nematisches Flüssigkristall-Material - vorzugsweise mit verdrehter Phase und gegebenenfalls mit Zusatz dichroitischer Farbstoffe - gewählt, das bei Ansteuerung seiner Elektrodengruppen-Paare mit einer Frequenz oberhalb eines materialspezifischen Übergangs-Frequenzwertes eine dielektrische Anisotropie anderen Vorzeichens aufweist, als bei Ansteuerung unterhalb jenen Übergangs-Frequenzwertes, mit umgebungstemperaturabhängiger Verschiebung des Übergangs-Frequenzwertes. Dadurch kann die Ansteuerung mit unabhängig von der Umgebungstemperatur fest vorgegebenen Frequenzen und Amplituden erfolgen, weil die Vergrößerung des Betrages der dielektrischen Anisotropie bei niedrigeren Umgebungstemperaturen höhere Rückstellfeldkräfte erbringt. Anwendung beispielsweise bei großen im Freien installierten, also starken Umgebungstemperaturschwankungen ausgesetzten Anzeigetafeln, etwa für die Verkehrslenkung oder in Sportstätten.

Title: Pneumatically operating control device for automatically aligning the beam width of the headlights of motor vehicles
Inventor: ANDRES RUDOLF
IPC: B60Q1/105
Filed: 1982-11-25
Abstract: Pneumatically operating control device for automatically aligning the beam width of the headlights of motor vehicles, having pneumatic control elements whose control pistons are acted on with control pressure which corresponds to the respective load-dependent distance between the body and the two axles of the motor vehicle. The optimal utilisation of a pressure accumulator from which pressure is obtained for the purpose of control and which is complemented as a function of the driving state of the motor vehicle takes place by intermediate connection of the shut-off component of a shut-off valve in the control line leading to the control elements. The shut-off valve can be actuated directly from the pressure accumulator and interrupts the control line, said valve being triggered in a manner which is as sensitive as possible and at variable pressures, with a constant pressure difference between accumulator pressure and control pressure. With respect to the sensitivity, further improvements are possible by arranging a further shut-off valve in the control circuit.
