Title: Apparatus for the continuous wet treatment of web-like textile material
IPC: D06B3/20
Filed: 1987-06-27
Abstract: The perforated-cylinder washing machine consists of three concentrically arranged units. The textile material rests on the outer perforated cylinder. It is mounted freely rotatably. The stator is located inside with a slight clearance and is arranged fixedly for the purpose of directing the fluid flow. The rotor is in turn located inside the stator with a greater radial clearance and has blades reaching into the vicinity of the inner wall of the stator. The blades of the rotor extend helically around the core of the rotor, preferably mirror-symmetrically from the centre and in a manner respectively offset rearwards in relation to the direction of rotation of the rotor. In addition, the annular space between the core of the rotor and the inner wall of the stator is formed on the two end faces, that is to say on the two ends of the washing apparatus, in such a way that the fluid accelerated axis-parallel to the rotor can flow out laterally. This fluid is expediently conveyed in the circuit, specifically to the treatment space and back onto the outside of the perforated cylinder. <IMAGE>

Abstract: A pick-up apparatus for a beet loading machine has conveyor screws (6, 6') which receive the beet from a beet pile (1) and which are pivotable towards one another in the horizontal plane in terms of their setting relative to the beet pile. The conveyor screws (6, 6') convey the received beet onto screening stars (17, 17'), from which the beet are transferred onto a screening band or the like and conveyed away. A respective conveyor screw and screening star constitute a unit, and the screening star receives a respective part frame (11, 11') of the associated conveyor screw. The conveyor screw or this part frame slides on runners. The part frame (11, 11') of the conveyor screw is so connected to the respective screening star that the conveyor screw and part frame are mounted in a manner articulated vertically to a limited extent. The part frames (11, 11') and their conveyor screws (6, 6') can preferably be swung in, so as to keep the width of the loader as small as possible for road travel. On their outer circumference, the conveyor screws (6, 6') have prong-shaped elements for cleaning the beet, or the conveyor screws are assigned separate devices which ensure that the beet are loosened from the beet pile, with simultaneous beet cleaning, and which transfer the beet to the associated conveyor screw. <IMAGE>

Title: Apparatus for the axial displacement of rollers in hot and cold rolling mills
Inventor: SETZER HELMUT
IPC: B21B31/18
Filed: 1987-07-03
Abstract: The invention relates to an apparatus for the axial displacement of rotating shafts, especially of rolls (2, 3) in hot or cold rolling mills, which are mounted in chocks, the rolls being set up so as to be displaceable axially in opposite directions relative to one another. Displacement devices of this kind are required, in particular, when using contoured rolls. In the known prior art, the rolls are displaced separately relative to one another, i.e. individually in an uncoupled manner. The measuring arrangements required for exact path determination in this case are very costly and prone to faults. According to the invention, the chocks of the rolls (2, 3), which are displaceable in pairs in opposite directions relative to one another, are connected via swivel joints (12, 13) to a common lever (10) which is designed so as to be pivotable about a fulcrum (11) by means of a drive, preferably a displacement cylinder (20). The swivel joints (12, 13) are expediently at equal distances from the fulcrum (11) of the lever. Work rolls and/or back-up rolls and/or intermediate rolls can be designed to be axially displaceable in pairs via respective common pivoted levers. <IMAGE>

Title: Arrangement for positioning a workpiece in a casting mould for an integrally cast clamping block
Inventor: LANGSTONE PAUL
IPC: B23Q3/18
Filed: 1987-08-17
Abstract: Workpieces which are difficult to clamp in place are integrally cast in so-called integrally cast clamping blocks. These are formed by casting around the workpiece with a meltable material in a casting mould. It is essential here that the workpiece is in a defined position in the casting mould before the pouring of the integrally cast material.   It is therefore proposed to provide positioning elements (3, 3a, 3b, 3c) in the casting mould (2). Upon contact with the workpiece (1), the positioning elements (3, 3a, 3b, 3c) specify a proper defined position of the workpiece in the casting mould, which is indicated on an indicating device (12). The positioning arrangement is intended in particular for the manufacture of integrally cast clamping blocks for workpieces which are difficult to clamp in place, for example turbine blades, which are subjected to machining on a machine tool, in particular a grinding machine. <IMAGE>

Title: Chain scraper conveyor having a plurality of drive stations arranged so as to be distributed over its length
Inventor: KETTERER KLAUS DIPL ING
IPC: B65G23/36
Filed: 1988-04-27
Abstract: In the case of chain scraper conveyors driven in a decentralised manner, the extensions which automatically occur during the running time of the chain scraper conveyor or of its chain belt can be compensated without problems in that the drive wheels which simultaneously drive the forward-motion chain and the return-motion chain are mounted so as to be displaceable in the longitudinal direction of the chains. The drive wheel can thus be displaced to the left or to the right depending on the extension occurring in the forward-motion chain or in the return-motion chain, so that uniform transmission of the drawing forces via the drive wheel is always ensured. <IMAGE>

Title: Hazard warning installation for motor cycles
IPC: B62J6/00
Filed: 1988-07-29
Abstract: To reduce the fitting and change-over times of the hazard warning installations of motor cycles, the direction indicator, which is already present, is used as hazard warning indicator and the direction indicator switch, which is already present, is used as operating switch. After a short changeover of the direction indicator switch from the right side to the left the hazard warning installation turns on the indicator lamps of the right side of the vehicle always when the indicator lamps of the left side of the vehicle are turned on by the turn-indicator lamp already present. This process is cancelled by a resetting part in the hazard warning installation when the direction indicator switch is set to the position "off" or "right".
Patent DE-3826254-A1 (DE)
Inventor: KOEN MYRON J
IPC: G11C27/02
Filed: 1988-08-02
Abstract: A 12 bit, 10 megahertz subranging analog-to-digital converter produces a sampled analog input signal 15. The sampled analog signal is converted by an MSB flash encoder 17 to a 7 bit MSB word that is converted to an analog signal by a 7 bit DAC 36 having 14 bit accuracy. The result is subtracted from the sampled analog signal 15 to produce a residue signal by means of a high speed amplifier having first and second multiplexed differential input stages, the first input stage (351, fig 4A) having differential inputs receiving the sampled analog input signal 15 and the analog signal produced by the 7 bit DAC 36. The second differential input stage (352) has one input connected to ground and the other input resistively coupled to the output of the high speed amplifier. The output of the high speed amplifier is resistively coupled to the second input of the first and second differential stages. The multiplexed input high speed amplifier produces an intermediate input level until the output of the DAC 36 is stable. Amplifying of the residue signal then begins from a balanced amplifier condition, and avoids delays that might result from an initial overdriven amplifier condition. The residue signal feeds an LSB flash encoder 48. The outputs of the two flash encoders 17, 48, are supplied to a digital error correcting circuit 61 supplying the 12 bit output 72. <IMAGE>

Title: Drilling device for producing drilled holes with undercut
Inventor: FISCHER ARTHUR PROF DR
IPC: B23B51/00
Filed: 1988-11-17
Abstract: Drilling devices for producing undercut drilled holes are known, said devices having a conical shape. To safeguard the drilled-hole mouth against damage and also to facilitate the swivelling-out during the performance of the swivelling movements to produce undercut drilled holes, while having to take account of the vibrations occurring in the course of the drilling operation, there is proposed a drilling device in which the drilling shank is located in a stop sleeve. In the region of the stop sleeve, the drilling shank has a collar, on the underside of which there are situated two concave curved washers lying loosely around the drilling shank. These washers take account of the swivelling movements and also, owing to their spring bearing, the vibrations occurring during the drilling operation and the discharge of drilling dust in the inner region.

Title: Large-calibre cluster munition (carrier projectile) for distributing practice bomblets
Inventor: ALTENAU ERNST-WILHELM DIPL ING
IPC: F42B12/62
Filed: 1988-12-10
Abstract: The invention relates to a practice unit composed of a special cluster munition and associated practice bomblets.

Title: Connection for the exhaust-air hose of a vacuum cleaner
Inventor: MAYR JOSEF
IPC: A47L9/00
Filed: 1988-01-26
Abstract: The exhaust air from every vacuum cleaner contains, owing to design factors, fine dust which is so fine that it is forced through the filter pores together with the exhaust air. Conventional vacuum cleaners blow the exhaust air laden with fine dust back into the room again. This is intolerable, for example, for those allergic to dust. Central house vacuum-cleaner installations, which certainly avoid this problem, can be retroactively installed only at great expense. It is also possible to convey the exhaust air from the vacuum cleaner via an exhaust-air hose into the open air simply by hanging the hose out of a window or the like. However, this has disadvantages. For example, for vacuuming, the window must be opened and the hose is not adequately fixed. Connections for the exhaust-air hose to wall outlets installed in the outside wall or to a blowing-out pipe or blowing-out piece avoid these disadvantages. They make possible a discharge conduit for the vacuum cleaner exhaust air laden with very fine dust into the open air which is simple to produce and is firmly installed or fixed.
