Abstract: The cleaning equipment has at least one cleaning unit and a propelling unit in hinged connection. The cleaning unit has cutting arms pivoted in a head. By means of a compact design of the cleaning unit or units with an axial length of the cutting arms substantially equal to the nominal diameter of the cleaning equipment and of the pipe to be cleaned respectively, by means of cutter arms extending substantially radially near said head, by the use of cutting knives of a substantially triangular sectional shape and having high torsional resistance, and by supporting the cutter arms by strong spring bundles a high cleaning efficiency of the cleaning equipment is obtained.

Abstract: A method for locating and evaluating surface and subsurface anomalies. Solar wind results in a multi-frequency, high energy ionic impingement at the terrestrial poles of the earth. Monitoring the activity of the solar wind allows the determination as to when the activity produces a vertical alternating current leakage (solar alternating current) due to the ionic impingement. When the vertical current leakage is in a proper range which can be measured and which reflects and represents surface and subterranean anomalies, a predetermined region of the earth to be prospected is traversed. Local variations which occur in the amplitude, frequency and frequency modulation of the vertical alternating current leakage due to the ionic impingement of solar winds at the terrestrial poles (solar alternating current) is measured. The measurements are recorded in correlation with the spatial relation to the points of measurement to determine significant measurements indicative of surface and subterranean anomalies.

Abstract: Apparatus and method for attaching tags to garments, gloves, handbags and the like includes an assembly for feeding tags from a stacked supply to a tag attaching station, an assembly for affixing the tag to the garment at the tag attaching station, and a control network for controlling and sequencing the tag feed and tag affixing operations. The tag feeding assembly includes a mechanism for gauging the width and thickness of a tag and for adjustably accommodating the same. The assembly also includes a pair of upright arms designed so that a tag having a prepunched hole can be placed with the hole over one of the arms. The other arm may be adjusted relative to the first arm and the positioned tag so that it touches the tag edge. The adjustment of the measuring arm automatically adapts the tag feed mechanism to precisely the required distance necessary to transport the tag from the stacked supply to the tag attaching station.

Abstract: The free-flow pump has an impeller housing (9, 10) laterally of its free flow chamber (4), and the impeller (6) is located in the impeller chamber (9, 10). The external, radial limiting member (10) of the impeller housing is drawn forwardly into the free flow chamber so as to decrease in the direction of rotation from the housing tongue (11) to the pressure pipe outlet. The limiting member (10) causes a constriction in the external portion (4') of the flow chamber, and such constriction decreases from the housing tongue towards the pressure pipe outlet. These measures permit the pump characteristics to be improved, and in particular the throttle characteristic of the free-flow pump can be stabilized.

Abstract: A device for balancing rotating bodies comprising two inertia masses, which are disposed in a cylindrical housing which can be connected to the body to be balanced such as a grinding disc, and which are mutually connected by means of a self-locking worm gear. The inertia masses may be displaced by means of one single switch shaft having four positions in which the two inertia masses can be displaced either countercurrently in both directions or concurrently. When braking is effected by means of a brake knob disposed on the switch shaft, displacement occurs until the indicated imbalance lies within the low, desirable range. The worm shaft and the worm wheel contained in the inertia masses are in engagement with the worm gear of the switch shaft and the housing.An arrangement of this type permits, on the one hand, a simple mechanical construction and operation, and, on the other hand, a large inertia mass, relative to the volume available, with a wide range of adjustment.

Abstract: A box-shaped article to be printed arrives on a conveyor belt and is stopped by a sluice-gate and, after said article has been released, it arrives on a conveyor slide in order to be brought onto a lifting platform. After the article has been raised to the level of the printing stations, all four sides of the article are printed simultaneously, the screen-printing method being used in particular.The apparatus for carrying out the method comprises a conveyor belt, a sluice-gate, a conveyor slide and a lifting platform. The lifting platform serves to raise the box to the level of the printing stations which are arranged so as to print all four sides of the box simultaneously. The box is aligned relative to the printing stations by means of a positioning mechanism and securely clamped.
