Patent DE-3206844-A1 (DE)
Title: Safety device for bands, belts, ropes or the like running on rollers, especially for conveyor bands
Inventor: CLEMENS DETLEV
IPC: B65G43/00
Filed: 1982-02-26
Abstract: The invention relates to a safety device for bands or the like running on rollers, especially for conveyor bands, in the region of their rollers assigned to the lower strand. These rollers are places where there is a danger that persons stopping in the region of the conveyor band will be pulled in. The safety devices, for example in the form of rigidly arranged filling bodies or protective baskets, hitherto provided in front of the run-on points of the lower strand afford only insufficient protection against the danger of being pulled in. Light barriers or such light switches, which are arranged in the pull-in regions on the lower strand in front of the corresponding rollers and which can switch off the drive motor of the conveyor band, are also inadequate, since, after a switch-off, there is still the danger of being pulled in because of the band follow-up. When the danger of being pulled in threatens, the safety device according to the invention reliably prevents personal injuries, in that the rollers (11) to be guarded are held releasably, and, when one of the electrical switching devices (42) responds, they are freed by a release mechanism (30, 34, 35), in order to make it possible for the respective roller (11) to swing down to a limited extent. The gap occurring between the released roller and the underside of the lower strand is sufficiently large to prevent injuries caused by being pulled in. The main use of the invention is in conveyor bands in the rocks and earth industry or in mining. <IMAGE>

In a further exemplary embodiment of the invention, the basic body (1) has an end bore (7) with an internal thread (8) into which a support taper (9) with indexable inserts arranged in slots (13) can be screwed by means of a bolt (10) with an external thread (11).
Patent DE-3211703-A1 (DE)
Title: Use of low-gold noble-metal alloys for dental purposes
Inventor: KNOSP HELMUT DIPL PHYS DR
IPC: C22C5/04
Filed: 1982-03-30
Abstract: The alloys have good material bonding between the metal structure and the dental ceramic, have good processing properties, are not brittle at elevated temperature, do not discolour, in particular when the ceramic is fired, and in addition are inexpensive. Silver-containing alloys tend to discolour the ceramic; alloys containing a small amount of silver or none at all tend to be brittle at elevated temperatures. Surprisingly, it has been found that the disadvantages described do not occur if platinum and/or at least one of the transition metals from sub-group 4, 5 and 6 of the Periodic Table of the Elements are added to the low-gold noble-metal alloys.

Patent DE-3226463-A1 (DE)
Title: Machine for tool grinding
Inventor: MAAS GEB SCHMALZ
IPC: B24B41/06
Filed: 1982-07-15
Abstract: In machines for tool grinding, the tool holder generally consists of two clamping jaws whose clamping surfaces, as a result of their lower degree of hardness with respect to the tools to be ground, become notched upon prolonged use making an exact, axis-true clamping of the tool impossible. With known tool holders it is always only possible to grind a very limited number of different drills of various diameters, so that such a grinding machine requires a large number of exchangeable tool holders. To avoid these disadvantages, it is proposed, according to the invention, to provide the clamping cams with exchangeable inserts made of a relatively hard material, which are not only suitable, due to their profile, for drills of widely differing diameters, but also have a nose projecting beyond the front face of the clamping jaws, so that the tool to be ground can be clamped very near its front end without the tool holder causing an obstruction as the tool approaches the grinding element. <IMAGE>

Title: Opening device in an open-end rotor spinning unit
Inventor: CHRTEK MILAN DIPL ING
IPC: D01H4/32
Filed: 1982-12-15
Abstract: The invention relates to an open-end rotor spinning unit. One problem in open-end rotor spinning units is the removal of impurities from a cleaning orifice and a removal channel of the opening device. The object on which the invention is based is to prevent the return of impurities to the opening roller with a minimum energy requirement. According to the invention, this object is achieved in that a continuous air-transport channel (20) is equipped, in front of or at the location of the outlet orifice (19) of a dirt-removal channel (18) in the air-flow direction, with at least one tapering wall (22) for reducing the cross-section and, behind the outlet orifice (19), with at least one widening wall (23) for widening the cross-section of the continuous air-transport channel (20). <IMAGE>

Title: Electropneumatic hammer drill
Inventor: FUCHS MICHAEL ING GRAD
IPC: B25D17/24
Filed: 1983-06-01
Abstract: An electropneumatic hammer drill in which the drive piston and open percussion member are accommodated in a cylindrical guide tube which is centred in the drill casing is to be improved such that the design and arrangement of the guide tube is less expensive and more favourable conditions with respect to the quiet running of the percussion mechanism are obtained. For this purpose, it is proposed that the two end faces of the guide tube possess axial play and the securing of the guide tube against axial displacement is effected by means of resilient elements which are supported, on the one hand, on casing-side fixed abutments and, on the other hand, directly or indirectly on the guide tube (Fig. 1).   <IMAGE>

Patent DE-3325550-A1 (DE)
Title: Arrangement and method for generating release signals
Inventor: BENSON MICHAEL RALPH
IPC: G01D18/00
Filed: 1983-07-15
Abstract: An arrangement for the accurate filling of analog values can be tested by using a short-duration test protocol for using and analysing all functions of the arrangement, which then automatically returns to the precise status existing before the test protocol was implemented. A time interval of the order of magnitude of one millisecond is reserved for feeding in test pulses, for the settling time and the return of the arrangement to its initial state. The correct return of the arrangement to its initial state before the test is critical so that the generation of a state ambiguity due to programmed hysteresis is avoided in the analog trigger values. An embodiment of an analog trigger module contains a preprocessing circuit (14) which is connected to an analog signal source (16) and to a diagnostic test circuit (36, 41), and a circuit module (10) which receives signals from the preprocessing circuit (14). The module (10) contains several trigger indicators (18, 20, 22) and a circuit arrangement for detecting coarse failures. The diagnostic circuit (36, 41) applies the test signals to the preprocessing circuit (14), both for testing and for resetting the trigger indicators (18, 20, 22). <IMAGE>

Patent DE-3325945-A1 (DE)
Title: Fibre-optical sensor and a sensor device containing the former
Inventor: EPWORTH RICHARD EDWARD
IPC: G01H9/00
Filed: 1983-07-19
Abstract: A fibre-optical sensor is specified in which an external influencing variable acting on the sensor is detected by the fact that it produces a detectable coupling of two modes or polarisations in the fibre. In one illustrative embodiment of the invention (Figure 10), an optical fibre is constructed in one or a number of successive fibre sections in such a manner that a change in the influencing variable, for example pressure, magnetic field or temperature, directly influences the mode coupling in the relevant section. In a second illustrative embodiment, the influencing variable acts in one or a number of successive fibre sections via a means deforming the relevant fibre section in a wave-like manner in a longitudinal direction, the mode coupling in each case only occurring with a particular length of the light guided in the fibre. Thus, the effect of the influencing variable on a fibre-optical sensor having several successive sensor sections can be spatially resolved by evaluating the wavelength at which the mode coupling is changed by the influencing variable. The optical fibre can either have a coaxial fibre structure (Figure 10) having two closely adjacent light-wave-guiding regions, in which the modes coupling with one another are guided in different optical wave guide ranges (1, 3) of the same fibre, or it can be a normal monomode- or multimode-fibre with a single wavelength range in which both modes or polarisations coupled to one another are guided. <IMAGE>

Title: Stand for the display of articles
Inventor: FELSKOWSKY ROLF
IPC: A47F7/024
Filed: 1983-09-14
Abstract: A stand of this type has a stand frame (1), formed by frame parts (2, 3, 4, 5), and shelves (6). Articles (7) can be placed between the shelves (6) and the frame parts (4, 5), said articles being surrounded by holding edges (10, 11) arranged on the shelves (6) and frame parts (4, 5). By means of a blocking member (14) arranged in the shelves (6) or frame parts (4, 5), the free spacing between two shelves (6) or a shelf and a frame part can be reduced or enlarged by the height of a stroke (h) of a lifting element (23), as a result of which the article (7) is blocked or released for removal. For this purpose, a blocking web (17) is brought into the blocking or unblocking position by the lifting element (23) via a blocking slide (18). Despite the direct possibility of viewing, which is not covered by any windows, removal of articles (7) is reliably prevented in the blocking position of the blocking web (17). <IMAGE>

Title: Device for changing the supporting effect of power-assisted steering in a motor vehicle as a function of the travelling speed
Inventor: BOGNER FRANZ DIPL ING
IPC: B62D6/02
Filed: 1983-09-28
Abstract: In a device for changing the supporting effect of power-assisted steering in a motor vehicle as a function of the travelling speed, having an intake-controlled steering pump which feeds a hydraulic fluid from a reservoir to a steering valve and also back to the reservoir therefrom, the pressure acting on the hydraulic fluid in the reservoir can be changed in a simple and cost-effective manner by means which are dependent on the traveling speed (partial vacuum pump which is driven via the speedometer drive). By means of these pressure changes, the feeding power of the steering pump is progressively reduced as the traveling speed increases.

Title: Process and apparatus for isolating dry solids from suspensions
Inventor: ULLRICH HANSJUERGEN DIPL ING D
IPC: B01D29/78
Filed: 1983-10-24
Abstract: The invention relates to a process for isolating dry solids from suspensions by filtration, if required, washing the filter cake, and subsequent drying and an apparatus for carrying out this process. The known filter driers carry out the process steps mentioned in one apparatus. They operate in the drying phase as paddle driers and thus stress the product to a considerable extent both mechanically (by the constant beating with the aid of a multifunctional agitator not optimally designed for the purpose) and thermally (by the strong heating of the product particles in immediate contact with the wall). Construction of the driers is laborious and correspondingly expensive, since these filter driers must be able to tip or pivot. The process according to the invention combines filtration and, if required, washing the filter cake, with fluidised bed drying and the apparatus according to the invention likewise carries out these process steps in a single unit. The fluidised bed drying is particularly gentle to the product both mechanically and thermally, and at the same time is also a rapid and thus economical drying process. The fluidised bed filter drier according to the invention does not require a tilting or pivoting device and is thus simpler and cheaper than the known filter driers. By means of the invention the advantages of the known filter driers as multifunctional apparatuses are thus maintained, ... Original abstract incomplete.
