Patent DE-3126105-A1 (DE)
Title: Sensor arrangement
Inventor: BOLLWEBER LOTHAR
IPC: G01F23/24
Filed: 1981-07-02
Abstract: A sensor arrangement for detecting the filling level of a conductive liquid (11) in a container (10) is proposed in which the output signal of an oscillator (13) is introduced into the liquid (11) via the probe (12) and the container (10) is preferably connected to reference potential. The signal dropped across the probe (12) is compared with the output signal of the oscillator (13) in a logical decision circuit. If the electrode (12) is immersed in the liquid (11), the signal present at the electrode (12) is zero, and if the probe (12) emerges from the liquid (11), the full output signal of the oscillator (13) is present at the electrode. Thus, by comparing the probe signal and the oscillator output signal, a switching signal can be generated in dependence on whether the probe (12) is immersed in the liquid (11) or not. The sensor arrangement is advantageously suitable for indicating the filling level in coolant, washing water or the like of motor vehicles. <IMAGE>

The ground-working implement is located between the push legs and the carrying legs, in front of the supporting frames in the direction of advance.
Patent DE-3128135-A1 (DE)
Title: Device for testing the rate of delivery of drive pumps on vertical hydraulic presses
Inventor: VERHEYEN ROLAND
IPC: G01M13/00
Filed: 1981-07-16
Abstract: The efficiency of the drive pumps of hydraulic presses has to be checked as a maintenance measure. In this case, the drive pumps serve both for the pressing stroke and for the return of the ram or the running bar. The particular rate of delivery is measured in the unit of time. In order to avoid complicated measuring devices, such as calibrated orifices arranged outside the press with measurement of the differential pressure upstream and downstream of the orifice, a simplification of this measurement of the rate of delivery is undertaken here. A drive pump hydraulically pressurises return cylinders in order to raise the ram against the weight thereof. In the process, a cam arranged on the ram actuates a position sensor provided on the stationary press part. Said sensor forms the initial point of a test stroke, which can be read off on a scale provided on the stationary press part. The position sensor is electrically connected to a time relay which is set to a time provided, and upon expiry separates the drive pump from the return cylinders of the press via control (manipulating) valves operated remotely by electricity. The return stroke executed uptil then is a measure of the rate of delivery.

Patent DE-3143153-A1 (DE)
Title: Process for the preparation of isobutyric anhydride
Inventor: NORTON RICHARD V
IPC: C07C51/58
Filed: 1981-10-30
Abstract: The invention relates to a process for the preparation of isobutyric anhydride, in which propylene is first carbonylated in the presence of a substantial molar excess of liquid anhydrous hydrogen fluoride, resulting in a reaction mixture of isobutyryl fluoride and unconverted HF. In order to recover the HF for recycling into the reaction cycle, the reaction mixture is then distilled. The isobutyryl fluoride residue is partially hydrolysed in the presence of an HF acceptor, giving a hydrolysis product consisting essentially of isobutyryl fluoride, isobutyric anhydride and a hydrogen fluoride complex of the acceptor mentioned. After removal of the solid complex, the hydrolysis product is subjected to fractional distillation, giving a top fraction of isobutyryl fluoride which is again recycled into the reaction cycle in order to be fed into the hydrolysis reaction.

Title: Switchgear cabinet for holding electrical and/or electronic assemblies
Inventor: GRUNWALD MATTHIAS
IPC: H02B1/30
Filed: 1982-01-22
Abstract: Switchgear cabinets of this type preferably consist of a stable framework to which the cabinet wall parts are screwed. At the same time, the framework is used for the fitment of the instrument and assembly boards which are arranged in the space inside the cabinet. Because these parts are attached to the vertical frame parts, the latter must be of suitably stable construction. By means of the present invention, it is intended to construct a switchgear cabinet such that its instrument and assembly boards are supported and held independently of the construction of a framework, so that a relatively light construction of the actual cabinet part can be provided. In this case, the rear wall (4) together with the lower and/or upper end wall (5, 6) are constructed as a closed integral unit which is equipped with folds (7), which point away at right angles, for holding the side parts (8), a self-supporting bracing unit (9) being arranged in the base region in order to absorb the vertical forces originating from the instrument and assembly board (3). <IMAGE>

Title: Method of fastening tube shells to the outer wall of a process container and a tube shell for use with the method
Inventor: HIPP GEORG
IPC: B23P15/26
Filed: 1982-02-22
Abstract: The invention relates to a method of fastening tube shells to the outer wall of a process container, made for example of stainless steel, aluminium or special alloy, by the welding process. The invention consists in an automatic application of the tube shell and automatic welding being achieved by virtue of the fact that the tube shell is wound in endless length onto the container wall of the axially rotating container, and that an automatic welding unit with automatic weld tracking applies the welds arranged at the side surfaces of the tube shell. As calculations and tests have shown, the tube shell according to the invention is a very elastic construction element in combination with the casing of the process container. This is of advantage during start-up with hot operating media. In rigid constructions, the thermal shock occurring as a result brings about considerable thermal stresses, which are avoided in the present invention.

Title: Laying machine, especially cloth-laying machine
Inventor: JUNG ROLF
IPC: B65H45/103
Filed: 1982-05-15
Abstract: Cloth-laying machine having a laying carriage which is movable to and fro along a table and the drive control of which has for each end position of the laying carriage a control strip attachable to the table and extending in its longitudinal direction and a feeler attached to the laying carriage and intended for this control strip. So that it is possible, without exchanging this control strip, also to lay out cloth layers, the length of which is smaller than the sum of the braking travels of the laying carriage in front of its two end positions, the control strip is made longer than the braking travel of the laying carriage from its maximum travelling speed, and furthermore the control strip is attached to the table displaceably in the longitudinal direction of the latter, so that it can be displaced out of a first position, in which it is located nearest to the respective other end position of the laying carriage, into a position further removed.
Patent DE-3221476-A1 (DE)
Title: Colloid mill
Inventor: HEINRICH EBERHARD ING GRAD
IPC: B02C25/00
Filed: 1982-06-07
Abstract: The milling gap between the milling bodies in colloid mills must be set to an extremely narrow value, which hitherto could only be performed sensitively by hand. Particularly in milling of abrasive material, the milling gap enlarges very rapidly, however, so that constant adjustment is necessary. To avoid this manual work, which is always accompanied by a poor milling result, it is proposed according to the invention to monitor the milling gap by a sensor which is fitted to the stator and the signals of which are conducted to an evaluation electronics unit that effects the displacement of the stator by means of a servo device. <IMAGE>

Title: Splitting apparatus for paving stones and bricks
Inventor: PORSFELD FRIEDHELM
IPC: B23Q11/08
Filed: 1982-06-21
Abstract: A splitting apparatus for paving stones and bricks, with a top tool (10) mounted in a roughly C-shaped frame (12) in such a way that it can move vertically up and down above a rest (table 14) for the stone or brick material to be split. A bottom tool (16) arranged below the rest (table 14) is allocated to the top tool (10). During the splitting of the stone or brick material, the bottom tool (16) passes through an opening (slot 18), provided in the rest (table 14), so that the top tool (10) and the bottom tool (16) come into action simultaneously for precision splitting. For this purpose, the rest (table 14), controlled independently of the splitting pressure or the splitting force, is lowered relative to the fixed bottom tool (16). In order to avoid a deviation of the top tool (10) to the side or to the front, especially during the splitting of stones or bricks having pronounced bevels on the top sides, the top tool (10) is held and guided on the upright stand column (20) of the C-shaped frame (12) by means of a linear bearing (32). <IMAGE>
