Patent DE-3303019-A1 (DE)
Title: Method for producing fluidised beds in the vicinity of the wall of the cooling tubes of surface heat exchangers
Inventor: CZICHON PAUL
IPC: F28F13/12
Filed: 1983-01-29
Abstract: The heat exchange in a surface heat exchanger is complicated in the interior of the cooling tube by two processes:   particle movement which is too small in the vicinity of the wall of the cooling tubes, and thus worsening of the heat transfer, disturbance of the heat conduction due to deposition of dirt on the cooling tube surface.   It is the object of the method to intensify the movement of particles, in order in this way to improve the heat transfer and at the same time to prevent the deposition of dirt. For this purpose, a worm which is set rotating by the flow is rotatably anchored in the cooling tube. This rotation of the worm intensifies the movement of the particles and thereby improves the heat transfer. At the same time, the rotation of the worm causes wall friction which prevents the deposition of dirt. The method is suitable for all heat exchange processes in surface heat exchangers standing vertically or lying horizontally.

Title: Boundary device for a flat roof
Inventor: HOUBEN DIETMAR
IPC: E04D13/155
Filed: 1983-03-04
Abstract: The boundary device has a plurality of angular holders (14) to be fastened, mutually spaced, to a roof surface. Situated between a horizontal first leg (141) and a vertical second leg (143) of the holder (14) is a U-shaped loop for forming a pocket (142). The roof-sealing sheet (17) lies on a continuous supporting profile (15) supported by supporting elements (144) of the holders (14). The end (171) of the roof-sealing sheet (17) is fixed in a gap (16) between the supporting profile (15) and the second legs (143). The end (171) of the roof-sealing sheet (17) reaches into the pockets (142), in which it is guided - reaching a level below the level of the legs (141). <IMAGE>

Title: Radial jet group missiles steering device - aligns missile's longitudinal axis on target by selective thrust control of nozzles paired in orthogonal planes
Inventor: TARRANT GEORGE ALEXANDER
IPC: F41G7/22
Filed: 1983-03-29
Abstract: A ground-target seeker (1) measures the angle between the axis (X) of the missile and the line of sight (Y) of the target. An amplifier-compensator (4) produces a differential thrust command signal (delta T) while an amplifier-integrator (5) provides a signal proportional to the lateral thrust (T) for alignment with the target. Sum and difference signals (6,7) are imposed on a sawtooth carrier wave (8) to generate variable-width pulse (9,10) for electromagnets (11,12) operating forward and rearward pairs of diametrically-opposed radial nozzles (2a). ADVANTAGE - Missile is controllable even at low speeds where aerodynamic external rudder surfaces are ineffective.

Title: Process and apparatus for optimising the maturing and drying of sausage, ham or similar foods
Inventor: SCHULDT PETER DIPL ING
IPC: A23L13/70
Filed: 1984-03-31
Abstract: A process and an apparatus are described for optimising the maturing and drying of sausage, ham or similar foods, water being removed from the material to be treated by supplying optionally conditioned air, until the desired degree of drying and degree of maturity is achieved. The controlled addition of outside air to the circulated air before its renewed entry into the treatment chamber (40) is carried out. The addition of the outside air is carried out in relation to the temperature and moisture in the treatment chamber (40) and in relation to the suitability of the outside air to contribute to cooling and dehumidifying the air in the treatment chamber. With a suitable addition of outside air, the period of use of mechanical accessory units can be reduced and thus considerable energy can be saved. <IMAGE>

Title: Interface for the digital storage of data on magnetic tapes
Inventor: NOBIS HANS
IPC: G11B20/14
Filed: 1984-08-04
Abstract: The invention relates to an electronic process for the storage of digital information and signals on magnetic tapes and the reduction of interference effects on serial data transmission channels. The invention is based on the object of perfecting the known processes by introducing a tolerance zone, so that even when less sophisticated drives or cassettes are used a considerably greater data integrity is achieved, without data being lost or having to be recorded more than once. The essence of the invention is that the assignment of the bit significance is derived not only from self-contained signal specifics, but also by logical comparison with a frequency spectrum. The number of signals for a bit statement can fluctuate within freely selectable tolerance limits without the information being falsified. Bit checking can be performed by counting the registered signals in a synchronised time frame and comparison with the predetermined tolerance zone.

Patent DE-3447419-A1 (DE)
Title: Method for limit-position disconnection of actuating drives
Inventor: MATTERN HANS-NORBERT
IPC: G05D3/14
Filed: 1984-12-24
Abstract: A method is specified for limit-position disconnection of actuating drives having an electric motor and having position-dependent switches, in the case of which the previous movement direction of the actuating drive is blocked on reaching a limit position. The actuating drive which is used is blocking resistant. There is a proportional relationship between the duration of an actuating signal and the adjustment of the actuating drive. The position-dependent switches are positioned such that they have already responded before reaching the limit position of the actuating drive. Once a position-dependent switch has responded, the previous movement direction of the actuating drive is not blocked until the duration of the actuating signals supplied to the actuating drive for the previous movement direction, reduced by the duration of the actuating signals supplied to the actuating drive for the opposite movement direction, has reached a predetermined value which - taking into account the adjustment speed of the actuating drive - corresponds at least to the distance between the position-dependent switch and the limit position of the actuating drive. Furthermore, two circuit arrangements are specified for carrying out the above method.
Patent DE-3501757-A1 (DE)
Title: Vibration damper for electrical medium-voltage and high-voltage overhead lines
Inventor: THEDA FRANZ PROF DIPL ING
IPC: H02G7/14
Filed: 1985-01-21
Abstract: The phenomenon of "cable dancing", which is also referred to colloquially as "galloping", has for many years led to major defects, particularly in the case of medium-voltage and high-voltage overhead lines having important power-transmission tasks, up to destruction of the overhead cables as a consequence mainly of two-pole short-circuits, this being the case when the overhead cables of two phases approach or strike one another. Signs of galloping are and have been observed in particular on harnessed conductors. Galloping is understood to mean transverse and torsional oscillations in the band of low frequencies of less than 1 Hz, the wavelength in this case corresponding to twice the span distance. The amplitudes of the vertical oscillations can amount to several metres and those of the torsional oscillations to several degrees. Vibration dampers are proposed which are characterised by one or more straight tubes whose internal diameter is greater than the external diameter of the overhead cable. They are pushed over the overhead cable such that the catenary is not disturbed and they are freely rotatable. Adjusting rings are arranged between the tubes.

Abstract: A jet milling device has an arcuate mill (10) with a milling chamber (12) in which the particles are pulverised in the vortex of a gaseous medium. In addition, the said milling device has a classifying component (16) which has a primary separator for separating the relatively small milled particles from the larger milled particles by centrifugal effect, a gravity chute (18) which leads back from the classifying component (16) to the milling chamber (12), and a secondary separator for classifying the smaller particles into fine-grade and very fine-grade particles by centrifugal effect. The secondary separator consists of two coaxial tubular nozzles, arranged in opposite directions, in the classifying component (16). The two nozzles have diameters of different sizes and are arranged at a radial distance from one another. The smaller nozzle is connected to an output and the other nozzle is connected to the milling chamber (12), the very fine-grade particles being sucked into the smaller nozzle and the fine-grade particles being carried from the annular chamber between the two nozzles to an output chamber (36).
