Title: Circuit for changing the image size of a television receiver
Inventor: HAFERL PETER EDUARD
IPC: H04N3/22
Filed: 1984-02-21
Abstract: A horizontal deflection circuit (22) periodically conducts a horizontal forward trace voltage to a horizontal deflection winding (LH) for generating a horizontal deflection current in the latter. A modulator circuit (25) responds to adjustment signals for changing the horizontal forward trace voltage whilst simultaneously changing the amplitude of the horizontal forward trace current. A pin cushion correction adjustment signal is supplied to the modulator circuit (25) for changing the vertical frequency of the horizontal forward trace voltage in order to provide for amplitude changes in the horizontal deflection current in the sense of an east/west pin cushion correction. A horizontal size adjustment signal (at 29) is supplied to the modulator circuit (25) for changing the horizontal forward trace voltage in order to change the image size in the horizontal direction. A vertical deflection circuit 28 generates, in a vertical deflection winding (LV) a vertical deflection current, the amplitude of which changes with changes in a vertical size adjustment signal in order to change the image size in the vertical direction. <IMAGE>

Title: Method for controlling the gravity flow of pulverulent or granular material
Inventor: MORIYAMA TAKASHI
IPC: B65G53/66
Filed: 1984-05-02
Abstract: A method for controlling a mass flow rate of a gravity flow of a pulverulent material fluidised in a closed container is specified, in which the fluidised pulverulent material is introduced into the conveyor line in such a way that it falls downwards along the line as a consequence of gravity. A bent section, a horizontal section, an obliquely extending section, a fixed throttle point, a weir and the like are provided in the lower section of the conveyor line, which extends approximately in a vertical direction, as a result of which the density of the gravity flow of the pulverulent material in the conveyor line is kept approximately equal to that in a plant having a moving bed. A gas is fed to the intermediate section of the conveyor line, and the feed rate of the gas is controlled, as a result of which the friction force of the pulverulent material is reduced at a second side of the conveyor line, so that the mass flow rate of the gravity flow of the pulverulent material can be controlled. The mass flow rate of the pulverulent material is determined on the basis of a pressure drop in a predetermined section of the conveyor line, on the basis of a fluctuation phenomenon due to fluctuations in noise or pressure, or on the basis of a differential pressure between the pressure at the end of the conveyor line near the ground and the pressure in a main confluence line, ...

Patent DE-3431467-A1 (DE)
Title: Fine-spinning apparatus
Inventor: ROEDLICH HUBERTUS DIPL ING
IPC: D01H1/08
Filed: 1984-08-27
Abstract: What is described is an apparatus for the fine spinning of a fibre sliver, by means of which a precisely defined twist can be imparted to a fibre string in a simple way, without the spinning speed being limited. For this purpose, the apparatus contains a take-up device rotatable about an axis of rotation and containing a yarn channel which is offset eccentrically from the axis of rotation in at least one portion. The draw-off force of the fibre sliver through the yarn channel is coordinated with the rotational speed of the take-up device, in such a way that the fibre sliver is pressed against the inner wall of the yarn channel by means of the centrifugal force and is taken up by the said inner wall in eccentric rotation, in such a way that the fibre string is twisted on itself. In a specially preferred exemplary embodiment, the take-up device contains a hollow shaft with a widened region, in which a tube acting as a positive guide for the fibre string is inserted in a zig-zag-shaped manner, in such a way that at least two portions offset eccentrically to the axis of rotation are formed.

Title: System for rapid identification of a digitally coded character sequence
Inventor: BOLLINGER ULRICH
IPC: G06F17/30
Filed: 1984-11-08
Abstract: The invention relates to a system for identifying digitally coded character sequences, which system is used, for example, in procedure analyzers for remote data processing or in database systems. The possible conditions during the search process are calculated in advance and are stored in a memory as condition tables. The characters to be searched for (investigated) are used for addressing the memory with the contents (condition identifier) set back in a delayed manner. In consequence, a self-controlling search process is achieved whose time duration is independent of the length of the character chain to be investigated. The maximum search speed is determined only by the access time of the memory which is used.

Title: Method for controlling the load take-up on sliding-shoe bearings
Inventor: ANSEN JAKOB
IPC: F16C17/20
Filed: 1984-12-05
Abstract: In known sliding-shoe bearings, in particular in known hydrodynamic sliding-shoe bearings which have at least one main sliding shoe and a relief sliding shoe, the setting and maintenance of a particular bearing gap presents difficulties and these can have a disadvantageous effect, in particular, on the emergency running properties of the sliding-shoe bearing. According to the invention, however, the setting and maintenance of a load-dependent bearing gap in hydrodynamic sliding-shoe bearings and hence an improvement in the emergency running properties is achieved by virtue of the fact that the outflow of oil and/or the outflow pressure of the oil is measured and that the load take-up of the relief sliding shoe is controlled as a function of the measured values determined during this measurement.

Title: Antifreezing arrangement for diesel fuel in engines
Inventor: BURSALIOGLU MEHMET
IPC: F02B3/06
Filed: 1985-01-24
Abstract: In order to prevent the freezing up of diesel fuel systems in diesel motor vehicles, a system is designed which utilises available hot air, available hot water and available battery current. The heat of the exhaust system is used to produce warm air and to conduct it to those points in the diesel motor vehicle which in winter, especially at extremely low temperatures, make the motor vehicle unfit for operation. At the same time, in addition, exhaust emissions as in summer are obtained. The system functions in a similar way using hot water from the water pump instead of the heat of the exhaust system. This represents an alternative for motor vehicles with cooling water system. In addition at extremely low temperatures battery current is used for the heating of points especially prone to freezing.
