Title: Detecting irregularities in painted metal sheet - using additional amplitude threshold switch for driving additional display diode
Inventor: KRIHA RUDOLF
IPC: G01N27/82
Filed: 1980-09-26
Abstract: The arrangement for detecting irregularities in a metal sheet covered with a smooth non-metallic coat using an inductive sensor is esp. useful for locating bumps in vehicle body panels which have been painted. The arrangement eliminates the hitherto necessary range changing when the metal changes from a ferrous to a non-ferrous metal. The arrangement contains an additional amplitude threshold switch connected to the rectifier downstream of the voltage stabilised oscillator. The additional threshold switch drives a second light emitting diode. The line between the oscillator and resonant circuit is connected to the input of a voltage amplifier whose output is rectified and displayed on an analogue indicator. The indicator or its scale can be switched by the output of the original threshold switch.

Title: Sewing machine work analysis - uses pulses from main shaft for evaluation by timers and counters
Inventor: RAUH BERNHARD
IPC: G07C3/08
Filed: 1980-12-04
Abstract: The initiator (1), responding to the rotation of the main shaft of the sewing machine, delivers pulse trains to an analyser where there is a pulse recognition stage (6) with gate control (10,11) to give measurement of the pulse trains, at two counting stages (8,9) through a timer (7) which registers the time span of the pulse trains and the pause time between pulse trains. The number of pulses is counted at a third counting stage (4) to be displayed (14) with the findings of all three counts (4,8,9). The counts are preferably recorded on a printer (15) and/or the impulses are written out (20), through processing the pulse trains through a digital/analogue converter (18), and/or displayed visually (19). The system reduces the time needed to analyse the workings of the sewing machine, or other appts., to identify the various work processes, and to record the performance.

Title: Metallically sealed pipe connection, especially for the food and pharmacology industries
Inventor: SCHLEICHER KARL DIPL ING
IPC: F16L23/036
Filed: 1981-02-14
Abstract: The invention relates to a metallically sealed pipe connection, especially for the food and pharmacology industries, which consists essentially of two flanges having outer welded ends in the axial direction, and the sealing effect is achieved between the flanges. In order to make it possible to use this metallically sealed pipe connection for very stringent hygienic requirements, that is to say to prevent gaps of any time at the abutment points, it is proposed that the flanges (1, 2) be centred (cf. 6, 20, 21) with respect to one another and the side surfaces of a metallic intermediate ring (6), whose unobstructed width corresponds to the unobstructed width of the flanges (1, 2), or the mutually facing flange surfaces themselves have circumferential sealing strips (7, 8 and 18, 19 respectively) directly on the fluid passage (cf. 3a, 6a, 4a and 3a, 4a respectively), that is to say on the edge of the unobstructed widths, which sealing strips, together with the other internal envelope surfaces, form a smooth passage (cf. 3a, 6a, 4a and 3a, 4a respectively). <IMAGE>

Title: Centrifuge which can be emptied hydraulically
Inventor: PASCHEDAG THEODOR
IPC: B04B1/14
Filed: 1981-03-12
Abstract: In a centrifuge with internal control piston which closes or opens discharge openings arranged at the periphery, a pressure chamber which controls the movement of the said piston is arranged between the latter and a lower component of the centrifuge. The emptying of the pressure chamber is controlled by means of hydraulically actuable valves. The supply of control fluid into the pressure chamber takes place by means of a central bore which extends in the shaft bearing the centrifuge whilst the valves are fed with control fluid via an annular chamber which is arranged in the lower component of the centrifuge and is open in the direction of the shaft. This spatial separation of the feed of the control fluids which serve different functions permits clearly defined control processes without mutual influencing.
Patent DE-3124866-A1 (DE)
Title: Method and apparatus for the numerically controlled cutting of a single-start or multi-start thread in at least two thread-cutting passes
Inventor: KIRCHHOFER HEINZ
IPC: G05B19/18
Filed: 1981-06-24
Abstract: The workpiece (1) to be provided with a single-start or multi-start thread is held in a main spindle (3) which is driven in a rotary manner by a drive motor (4). A cutting tool (8) is fed in the direction of the X- or Z-axis by means of two feed drives (12, 13). So that the approach distance which the cutting tool (8) has to cover until the desired feed rate is reached in the Z-direction is now kept short, the acceleration to be adhered to during the first thread-cutting pass is determined before the start of this first pass. This acceleration is calculated on condition that the approach during each thread-cutting pass takes place with the greatest possible acceleration but without a predetermined, maximum acceleration being exceeded. Since the approach during the first cutting pass does not take place with any assumed acceleration, but the acceleration to be adhered to is precalculated, this ensures that in the following thread-cutting passes the acceleration to be adhered to corresponds at most to this maximum acceleration and yet the shortest approach distance possible under the given conditions to be adhered to is never exceeded. <IMAGE>

Title: Device for strain measurement
Inventor: FORTMANN MANFRED DIPL ING
IPC: G01B7/16
Filed: 1982-03-04
Abstract: The present invention relates to a device for strain measurement, the capacitance of a capacitor being varied. The capacitor plates are mounted in this arrangement on a retaining strip which is sub-divided into a plurality of segments (2, 3, 4) which are held together via break points (5, 6). The retaining strip is bent into a U in the interior of which the capacitor plates are situated. The outer ends (2) of the retaining strip are attached to the structure (1). When there is a strain in the structure (1), the break point (6) acts like a joint, and the spacing of the capacitor plates (8) changes. As a result of the soft break points (6, 5) influences due to bending of the structure (1) are largely eliminated and a low hysteresis of the arrangement is achieved. <IMAGE>

Title: Antifreeze in the form of a paste
Inventor: KRAUSE GUENTER
IPC: C09K5/20
Filed: 1982-07-08
Abstract: In summary, the abovementioned inventive idea is useful for preparing antifreezes for lowering the freezing point. Unlike the already existing antifreezes in the liquid state, this one is in a flexible, paste-like state and can be filled into tubes or similar squeezable containers. If fairly large amounts are needed, any other containers suitable for this purpose can also be used. An air-tight foil packaging, such as, for example, aluminium foil or coated paper, is also sufficient. This is done by wrapping up the antifreeze composition, which may have been formed sausage-like in this packing material. The packing material is provided with labelling features which divide the antifreeze composition into such portions as required by the desired lowering of the freezing point relative to the necessary amount of water. The mixing example, by virtue of its composition, gives a flexible, paste-like composition after mixing, the powder and salt-portions serving simultaneously, apart from their other modes of action, as vehicles and binders for the liquid alcohol.
