Patent DE-3127604-A1 (DE)
Title: Method for optically determining texture directions of surfaces, and for orientating workpieces by means of their surface texture
Inventor: BODSCHWINNA HORST DR ING
IPC: G01B11/30
Filed: 1981-07-13
Abstract: During the scattering and diffraction of reflected or transmitted light, periodically or statistically arranged structural elements of surfaces cause a distribution of scattered light which, with reference to intensity and solid angle elements, contains information on the distribution and configuration of the surface elements. In the case of anisotropically textured surfaces, preferred directions of the surface structure can be determined from the distribution of scattered light, and, in the case of industrial surfaces, the direction of the tool marks can be determined, for example. The invention makes use of these relationships in order either visually or photoelectrically to measure structural parameters, or to use the latter to orientate workpieces for sorting and manipulating techniques or joining techniques. Fig. (1) represents a possible arrangement, in which a cylindrically represented object (6) scatters illuminating light which is incident normal to the cylinder surface, and the light is collected in the focal surface (8) of a lens (4a) which sorts the beam directions of the scattered light, and is transmitted by an auxiliary lens into the analytical plane (8') and evaluated there photoelectrically with regard to the distribution of intensity over the analytical plane. The eye lens (18) represented serves as an orientation aid for the position of the object relative to the measuring instrument. <IMAGE>

Title: Electrical filter circuit using a surface acoustic wave filter
Inventor: ECKERT BERTHOLD ING GRAD
IPC: H03H9/00
Filed: 1981-08-05
Abstract: The filter circuit is followed at the output by further circuit arrangements, particularly amplifier circuits, in such a manner that both connecting lines of a surface acoustic wave transducer are available. It is the object of the invention to compensate for interfering capacitances and to create an unbalanced output. According to the invention, this object is achieved by the fact that in both connecting lines (1, 1'), transforming low-pass filters (L/C) are provided which are preferably constructed to be similar with respect to one another and which consist of at least one series coil (2, 2') and possibly a parallel capacitor (3, 3'). <IMAGE>
Patent DE-3139078-A1 (DE)
Inventor: KLEIN JUERGEN DIPL PHYS DR
IPC: C01B31/08
Filed: 1981-10-01
Abstract: In a method for regeneration of moist powder adsorption agent, the moist-charged adsorption agent is first fed into the lower area of a fluidized bed which is provided with an aeration and heat-carrying material; the agent then is fed upwardly through the heat-carrying material while being simultaneously dried, and then the agent is withdrawn together with the vortex gas from the fluidized bed. The agent is separated from the vortex gas in a successively switched separator, and is then fed to a further fluidized bed which is provided with a further aeration and heat-carrying material. The agent is fed in that further bed upwardly through the further heat-carrying material and is simultaneously regenerated. The agent is then discharged together with the further vortex gas from the further fluidized bed. The vortex gases which are withdrawn can be reused as mixing gases during the vortex gas generation. The adsorption agent can be mixed with a sludge, for example, from a sewage treatment plant, which, if necessary, is gasified together with the substances of the adsorption agents in the regeneration step.

Title: Process for the compression and transfer of a sorptive used in a thermodynamic process and vaporised at a low temperature level
Inventor: KRANIGK HELMUT
IPC: F25B41/10
Filed: 1981-10-13
Abstract: In the refrigerant circulation of domestic refrigerators, it is known to use compressors which result in a sawtooth-shaped, undesired curve of the cooling temperature; moreover, noise of various frequencies is generated by the moving parts of the compressors, so that insulating means are required. It is the object of the invention to generate a continuous and controllable mass flow of the sorptive used in thermodynamic process systems; this is achieved by compressing and/or liquefying the vaporised sorptive in a capillary condensation process and effecting the transfer of the compressed and/or liquefied sorptive by the electro-osmosis process. <IMAGE>

Title: Method and arrangement for power control
Inventor: ALBRECHT WERNER DIPL ING
IPC: G05F1/44
Filed: 1982-04-06
Abstract: To be able to keep the power constant given fluctuations of the supply voltage, on a load (3) which can be cyclically switched on and off, an address signal for a correction value memory (8) is formed from the supply voltage with the aid of a A/D converter (7). The correction value in each case called up in this memory is supplied as correction value signal to a multiplication device (9) and to which a continuous switch-on signal is entered at the same time. The two aforementioned signals, to be considered as multiplicand and multiplier, generate an output signal at the multiplication device (9) which sets the switching-on and switching-off times for the control input of a controlling element (4) which is located in series with the load (3). <IMAGE>

Abstract: Valve coupling, in particular valve metering coupling for fluidic systems with high working pressures, comprising a coupling bush under line pressure, in the bore of which is arranged a spring-loaded and mechanically actuable nonreturn valve. In the closed valve condition, a cylindrical valve body presses with the outer edge and/or front face of its sealing shoulder against a sealing ring of elastomeric material which forms a sealable flow channel with the coupling bush or a sealing bush arranged in the coupling bush. Arranged downstream and/or upstream of the sealing ring are further seals which, when the valve body is pushed open, only end their sealing function after the lifting off of the sealing ring from the sealing shoulder, preferably with a delay.

Title: Clamping connector
Inventor: POGGEL MANFRED-JOSEF
IPC: F16B12/32
Filed: 1982-07-28
Abstract: In order to connect profile elements having grooves which run on one or a plurality of outer sides, a device is used which consists of a plug-in bush which is fixed in the profiled rod to be connected, and of a clamping bolt which has a head which projects over the profiled rod and can be inserted into the groove of the profile elements to be connected. The clamping bolt is arranged such that it can be pushed into the plug-in bush by means of an Allen-key headed bolt which is arranged such that it can rotate in the plug-in bush. Care is taken by means of a clamping spring to ensure that the connection can be released again quickly. Such clamping connectors allow, in particular, exhibition stands to be assembled very quickly and to be dismantled again, the vertical supporting element preferably being used as an element which internally has a rectangular recess with projecting slots on the diagonals. <IMAGE>

Title: Crushing machine for easily cut materials
Inventor: HERMEIER WILHELM DIPL ING
IPC: B02C18/22
Filed: 1982-10-18
Abstract: The machine consists of a rotating tool carrier which has the crushing tools and above which a funnel whose cross section increases upwards is arranged for the purpose of holding the materials. At least one lateral wall of this funnel consists of a device which conveys upwards on the inside of the funnel, is driven and is provided with drivers. Its lower part forms with the lateral wall of the funnel lying opposite it a slot through which the materials slip towards the crushing tools. By means of the upwards conveyance in the funnel, the material pieces which exceed the cross-section of the slot are transported backwards. They impact against other pieces of material which are also moved. Jamming of the pieces of material in the funnel which narrows towards the bottom is prevented and fault-free crushing of the contents of the funnel is ensured. <IMAGE>

IPC: G01F23/292
Filed: 1982-12-21
Abstract: A fibre-optic liquid-level measuring device has a first optical fibre (3) assigned to a light source (2) and a second optical fibre (4) assigned to a light detector (1). The two ends of the optical fibres (3, 4) are joined via a transparent joining element (7). The joining element couples a portion of the light from the optical fibre (3) into the optical fibre (4). The light intensity guided over is a function of the reflectance behaviour of the joining member (7). Depending on whether the joining member (7) dips into the liquid or not, more or less light is coupled into the optical fibre (4) and measured at the detector (1). <IMAGE>
