Patent DE-3541871-A1 (DE)
Title: Set of hydraulic pit props
Inventor: FAUST KURT
IPC: E21D15/44
Filed: 1985-11-27
Abstract: A set of hydraulic pit props suitable for the normal seam thicknesses contains only eight pit props which in each case can cover a larger thickness range on account of a greater extended length in relation to the retracted length. The more favourable ratio between extended and retracted length results from the setting and release valve being attached laterally to the bottom prop instead of in the top prop. In addition, it is arranged close to the handle of the pit prop. This improves the posture and the standing position of the man during setting and release. <IMAGE>

Patent DE-3605927-A1 (DE)
Title: Digital interpolator
Inventor: ALI AMAR DR
IPC: H03H17/06
Filed: 1986-02-25
Abstract: The invention relates to a digital interpolator for changing the sampling rate of a digital signal by the factor M:N (M and N integral numbers). (M-1) pseudo samples having the value zero are added to a sequence of samples in a first sampling circuit (AT1). This new sequence of samples passes through an ideal low-pass filter arrangement (TP) without group delay distortion, consisting of two identical simple low-pass filters with group delay distortion in conjunction with two buffer memories. The buffer memories provide for time-inversion of the signals so that, when the components are suitably interconnected, the group delay distortions of the two filters cancel one another. A second sampling circuit (AT2) following the low-pass filter (TP) then only samples every nth value of the interpolated sequence of samples. The interpolator is suitable, for example, for converting the sampling rates of video or audio signals.   <IMAGE>

Title: Method for the discharge control of hydraulic jigs
Inventor: REILARD ULRICH
IPC: B03B5/24
Filed: 1986-05-02
Abstract: In a method for the discharge control of hydraulic jigs, which discharge control is provided with a drive for actuating the discharge element in the opening direction and closing direction, a sensor which responds to the thickness of the heavy material layer in the discharge region, a first trigger which can be driven by the sensor when a specified maximum thickness of the heavy material layer is exceeded and which serves for switching over the drive into the opening direction, and a second trigger which can be driven by the sensor when the thickness valve of the heavy material layer drops below a specified minimum and which serves for switching over the drive into the closing direction, the vertical motion of the sensor and/or of the pulsation of the water in the hydraulic jig is detected. This vertical motion is used for correcting the distance between the upper and the lower maximum value of the position of the trigger which is used for switching over the drive of the discharge element and, at the same time, a displacement of the position of the maximum values is permitted without the distance of the maximum values being altered with respect to one another.

Patent DE-3733676-A1 (DE)
Title: Hydraulic clamping element
Inventor: EHRHARDT WINFRIED DIPL ING DR
IPC: B25B5/06
Filed: 1987-10-05
Abstract: The invention relates to a hydraulic clamping element for clamping moulds and tools or workpieces on machine tables in a straight clamping surface. The hydraulic clamping device consists of a wedge bolt and a clamping piece which are connected to one another via a sloping surface. The stroke of the clamping piece is limited in both directions so that during the clamping action first of all a displacement in the direction of the piston of the hydraulic cylinder for wedge bolt and clamping piece is effected until the clamping piece strikes a stop and then, by further travel of the wedge bolt, a pressure is exerted on the clamping piece perpendicularly to the piston direction and the clamping piece is firmly pressed onto the mould or the tool. Thus moulds and tools with a straight clamping surface can be used again, even in standardised size. The slope is made between wedge bolt and clamping piece in such a way that self-locking occurs so that the hydraulic pressure need not be maintained after the clamping action. To remove the workpiece or the mould, the clamping piece with the wedge bolt is moved completely into the housing so that the moulds and workpieces can easily be changed.

Title: Apparatus for separating packing units which have been recognised as being defective
Inventor: BRASCHOS ERDMANN
IPC: B65G47/84
Filed: 1987-10-13
Abstract: Apparatus for separating packaging units which have been recognised as being defective, in particular bottles. Such a separating apparatus, which is known from German Offenlegungsschrift 2924312, has a very complex design. The new separating apparatus is to be constructionally simplified. The separating apparatus is constructed in such a manner that the distance by which the bottles are displaced transversely to the belt running direction during separating is independent of their degree of filling and can be controlled by means of the drive. The separating apparatus for pushing defective bottles (2) from a main conveyor belt (3) onto a separating belt (6) comprises at least one brush roller (7) which is driven with temporal accuracy by means of a recognition station for defective bottles (2), the surface of which brush roller (7) is partially equipped with bristles (8) of equal length, the axis of rotation (9-9) of which brush roller (7) is arranged in a plane, parallel to the belt running plane, outside the movement path of the bottles (2) at an acute angle (alpha) to the main conveying direction (a) and which brush roller (7) is driven, as required, for one revolution per bottle to be separated. The separating apparatus is intended preferably for use in bottle treatment plants. <IMAGE>

Title: Oscillating-armature motor with amplitude monitoring
Inventor: BECKER KLAUS DIPL ING
IPC: H02P25/032
Filed: 1988-02-09
Abstract: The pattern of the stray magnetic field of an electric oscillating-armature motor alters positionally and temporally with its mechanical loading. A cost-efficient method is described for monitoring the amplitude or the load factor of an oscillating-armature motor. A magnetic sensor connected to an electronic circuit arrangement detects the pattern of the stray magnetic field and determines the loading factor therefrom.   As an important criterion, the harmonic distortion factor of the stray magnetic field is evaluated. The circuit arrangement emits a signal on passage above or below a predetermined loading factor. A particularly simple embodiment of the magnetic sensor is disclosed.

Title: Method for determining the pollution load in the external air and interior air with bioindicators
Inventor: BOMAR MIROSLAV THOMAS DR ING
IPC: C12Q1/02
Filed: 1988-04-02
Abstract: Pollution of the atmosphere and of the air breathed in the home environment and at the workplace is increasingly frequent and is caused by a large number of pollutants and toxic molecules. Technical and chemical test methods are able in each case to measure only one aspect of the actual pollution situation. For these reasons, there is increasing use of so-called bioindicators. This is based on the recognition that all environmental factors together have an effect on humans and on animals and plants. A method has been developed with standardisable bioindicators in the form of test microorganisms in pure cultures with the aim of detecting a toxicity present in the air even from unknown and low pollutant concentrations and the effects thereof (in particular after prolonged exposure). It comprises an extremely simple, reproducible method with a wide range of applications.
