Title: Voltage and resistance transformation of low-impedance voltage sources with currentless voltage pickup and preservation of the signal/noise ratio
Inventor: KROEBEL WERNER PROF DR
IPC: G01N27/06
Filed: 1984-03-01
Abstract: The application relates to a voltage and resistance transformation with low-impedance voltage sources and currentless voltage pickup whilst achieving an optimised signal/noise ratio. A solution of this problem is of significance in cases where, as, for example, in the case of electrolytic cells, accurate conductivity measurements are to be made. In these cells, the conductivity is determined by measuring a voltage drop by means of two electrodes which are in contact with the electrolyte. To avoid false measurements, the voltage must be picked up with extremely high impedance because of the familiar boundary-layer phenomena between metal electrodes and electrolyte. On the other hand, the electrolyte resistances between the electrodes are frequently lower by a factor of 100 than the equivalent input noise resistances of the connected amplifiers or circuits. A transformer which would allow noise-free resistance transformation for matching cannot be used because of the demand for high impedance of the connection. According to the concept of the invention, however, this can be achieved if the transformer effecting the resistance transformation is not fed from the voltage drop in the electrolyte but from a source via a regulation circuit for which the absence of current flow in the connections effects the control of the regulation stage. The secondary voltage of the transformer in this arrangement is controlled from a secondary source as determined by the control signals for the regulation stage.

Title: Process for removing sulphur and ash from coal particles
Inventor: GREENWALD SEN EDWARD HEINZ
IPC: B03B1/00
Filed: 1984-05-10
Abstract: The invention relates to a process for removing sulphur and ash, in particular clay and pyrite, from coal particles which have a mesh size of 30 or less. For this purpose, a suspension of coal particles is vigorously agitated in an ultrasonic mixer 34 in order to separate off admixtures from the coal and to attenuate the chemically bound contaminants on the surface of the coal. Clay particles and pyrite particles are dispersed as a colloid in the aqueous medium of the suspension. In the treatment of the suspension with sonic energy, the particles are also divided along the ash or clay fringe line. The suspension is then separated in a centrifuge 36 and in foam flotation cells 39, so that coal particles which are larger than two 2 microns are obtained which are resuspended. This suspension is then treated with sonic energy in a vessel 42 and in a vessel 43 with ozone in order to liberate further amounts of components situated on the surface from the coal particles. The further treatment of the suspension is again carried out in a centrifuge 46, coal particles being obtained which are 2 microns and above. Prior to each treatment with sonic energy and ozone, the suspension is adjusted to a pH of 6 to 9 in order to retain the liberated contaminants as suspended colloids in the aqueous medium of the suspension. <IMAGE>

Title: Transport cart, in particular shopping trolley
Inventor: EBERLEIN HERBERT DIPL ING
IPC: B62B5/02
Filed: 1984-09-18
Abstract: In the case of transport carts, in particular shopping trolleys, which are conveyed on moving walkways, it is sometimes necessary, depending on the type of moving walkways and the construction of such transport carts, to provide a lifting wheel at the end of the wheel frame. This lifting wheel facilitates the transfer of the transport cart from the conveyor belt to the solid walking area. In previously known transport carts the lifting wheel protrudes from the wheel frame in a manner which is annoying and likely to cause accidents. The invention eliminates this disadvantage by proposing a transport cart, in particular a shopping trolley (1), in which, when seen in plan view, at least the axle supports (16) of the lifting wheel (13) are arranged within the outline formed by the wheel frame (4). <IMAGE>

Title: Belt winder for roller shutters, blinds, sunshades or the like
IPC: E06B9/78
Filed: 1984-12-01
Abstract: In a belt winder for roller shutters, blinds, sunshades or the like, with a winder housing (10), in which a rotationally drivable belt-winding drum (11), on which the belt (18) is wound up, is mounted and which has a belt opening with, arranged in its region, a belt guide (20), operational disruptions are to be avoided, which can occur because, when the roller shutter is lowered or the sunshade has been extended, the fastening of the end of the belt (18) on the winding-drum side can be damaged or the belt (18) can be wound up in the wrong direction onto the winding drum (11). This is achieved by the end (17) of the belt (18) on the winder-housing side or a flexible connection part (19), which can be attached thereto, being fastened on the winding drum (11) via a unilaterally acting freewheel coupling in such a manner that, when the belt end (17) is tension-relieved and the winding drum (11) continues to rotate, the frictional connection between the latter and the belt end (17) or the connection part (19) is broken. Whereas the winding drum (11) securely grasps the belt end (17) or the end of the flexible connection part (19) during the winding-up movement, the belt end (17) is uncoupled from the winding drum (11) when the latter is rotated in the opposite direction. <IMAGE>
Patent DE-3446818-A1 (DE)
Inventor: WALLNER JOSEF
IPC: B29B7/76
Filed: 1984-12-21
Abstract: The mixing head is provided with a flow restrictor 5 which can be driven into the mixing chamber 2 downstream of the inlet orifices 3, and whose front face (for 6) is matched to the contour of the mixing chamber to avoid leaving any space here which cannot be purged by the purging plunger. When the flow restrictor is pushed forward into its working or restricting position, it is simultaneously rotated, the extent of rotation being no more than 90 DEG  by the time the restricting position has been reached. This makes it possible to drive the flow restrictor much further into the mixing chamber than when no rotation is effected. The tongues or projections 6 produced as a result of matching the front face to the contour of the mixing chamber only come into contact with the sections of the mixing chamber wall which are opposite the flow restrictor. The flow restrictor can be pushed in an appropriate distance, making it possible to achieve a good restricting effect and therefore to exert a corresponding great influence on the mixing procedure or on the discharge characteristics.

Title: Blocking device for safety belts
Inventor: SINGER KLAUS-PETER
IPC: B60R22/42
Filed: 1985-03-23
Abstract: In a blocking device for safety belts, especially in motor vehicles, with a self-locking belt retractor and with a clamping device, which brings about the blocking of the belt band and is arranged on the belt retractor and has a clamping jaw fixed to the housing and a movable clamping jaw, between which the belt band is guided, there is the problem that a multiple deflection of the belt band, with a corresponding rubbing stress and loss of comfort for the user, has hitherto been necessary with respect to the response of the clamping device reacting to a pull on the belt band. To solve this problem, it is proposed that the clamping device (15, 16) should engage on the belt band (17) running off from the belt roll, without any deflection of the belt band (17), and that the belt retractor (10), in the locked state, should as a whole or with individual parts (13, 14) actuate the clamping device (15, 16). <IMAGE>
Patent DE-3510691-A1 (DE)
Inventor: MUMCU SALIH DR
IPC: C08L77/00
Filed: 1985-03-23
Abstract: The invention concerns an improved precipitation process in the manufacture of coating powders based on polyamides having at least ten aliphatically bound carbon atoms per carbonamide group. Rapid cooling takes place with stirring mainly by distilling the ethanol solvent until the temperature of precipitation is set in the range from 90 DEG  to 113 DEG  C. With the beginning of the saturation limit (about 125 DEG  C.), the temperature difference between the coolant in the jacket and the solution inside is maintained at most at +/-3 DEG  C. The solution is maintained during the precipitation stage at constant temperature (isothermal procedure) by further distillation of the ethanol.

Patent DE-3527616-A1 (DE)
Title: Hard-shelled case, in particular spectacle case
Inventor: DIETERLE PETER
IPC: A45C11/24
Filed: 1985-08-01
Abstract: The invention contains an improvement in hard-shelled cases, in particular spectacle cases, which have a case-shell edge reinforcement in the form of a profiled strip. In the case of known hard-shelled cases part of the circumference of the lid-shell edge is bordered by a profiled strip which is U-shaped in cross-section and primarily serves aesthetic purposes but also partly serves to visually mark the lid-shell edge as compared to the trough-shell edge and thus to facilitate opening the case. The strength and rigidity of the known cases is determined by appropriate selection of material and constructional design of the lid and trough shell. According to the invention, the edges of both case shells (I, II) are each equipped with profiled strips (assembly frame 2) which enclose the entire shell circumference, are produced from a strong, rigid material which ensures adequate torsional rigidity, in particular metal or hard plastic, and on which both the closure elements (2a) and also the hinge elements (2b) of the case are fastened. By this means, it is possible, on the one hand, while substantially saving case-shell material nevertheless to attain the same case strength and rigidity as hitherto and, on the other hand, while providing only a few basic types of assembly frames to be able to prepare a virtually unlimited multiplicity of case types in terms of construction and appearance. <IMAGE>
