Abstract: Abstract of the Disclosure An endless net conveyor is suspended from a drive wheel which is mounted at an upper part of the apparatus, hanging into a treating bath, and a metal gauze member is extended along the outer periphery of the net conveyor thereby forming a U-shaped path between the net conveyor and the metal gauze member.  One upper opening part of the U-shaped path constitutes an introduction side for insertion of the fabric to be treated, and the other upper opening part of the U-shaped path constitutes an exit side for the treated fabric, both upper openings serving to convey the fabric continuously therethrough during treat-ment.  Injection pipes are provided in the bath on both exterior sides of the U-shaped path, namely on an inside side and on an outside side of the path, the injection ports of the pipes being alternatingly directed toward the path.  A circulation pump disposed outside of the bath circulates the treatment liquid, the suction side of the circulation pump being connected in communication with the treating bath inwardly of the net conveyor. The blowing side of the circulation pump is connected to the upper part of the U-shaped path and to the injection pipes on both the inside side and the outside side of the path, respectively, via injection-flow control valves.

Abstract: ABSTRACT OF THE DISCLOSURE            VAULTING PRACTICE BOX         There is provided a practice box for pole vaulters, which defines a wedge-shaped recess converging in the forward direction, open upwardly and open rearwardly.          The practice box has side edges defining the convergence, which side edges are provided with means for retaining the inertial weight in such a way as to oppose a forward thrust in the practice box.  In use the inertia of the practice box allows the vaulter at least to lift-off the ground, but the forward thrust exerted by the pole allows the vaulter to return to the ground without completing the jump.          The purpose is to permit practice of the lift-off without requiring a full jump.

Abstract: ABSTRACT OF THE DISCLOSURE         An electrical balance has a load receiving load pan, a circuit for supplying current pulses in dependence on the load being weighed, a summing means for counting the current pulses over respective predetermined time intervals to derive a quantity representing the weighing result, display means providing a digital indication thereof, and a control circuit for automatically predetermining the length of each time interval and for adapting the number of places of the indication at the display for either rapid rough weighing or at a higher sensitivity up to the maximum as the target weight is reached.         The balance has a weighing chamber having a door, the opening and closing of which is arranged to effect switching of a control circuit so that when substance is being placed on the pan, and a switch is actuated by the open door to a de-sensitizing position, the large variations in the sensor circuit exceed thresholds of a pair of comparator circuits, causing shortening of integration time to for example, 0.02 seconds, instead of 2 seconds.     The count of pulses is indicated lacking the last two digital positions, as a rough weighing. As the target weight is approached and minimal substance is added, the lesser deflection of the balance is sensed by the comparator circuits, causing a switch to be actuated to omit the last place only of the indication; finally when the door is closed a switching action restores the full resolution time and maximum sensitivity, i.e. slowest weighing.

Abstract: ABSTRACT OF DISCLOSURE:  Methods and apparatus are described for generating and transmitting signals in accordance with a sequence which defines the time relationship of the signals. Each signal has a band width covering several octaves and may be a pulse.  During a transmission interval the repetition frequencies of the signals monotonically sweep in a coherent relationship over bands restricted to an octave such that the spectrum of the sequence has substantially constant energy over a frequency range much larger than an octave. The autocorrelation function of the sequence is character-ized by an absence of side lobes which would indicate false targets or produce a high noise level upon processing of the signals in an echolocation system, such as a geophysical exploration system in which the seismograms are constructed by cross correlation of the signals which are received from the geological reflection surfaces with a stored replica of the transmitted signals.  The signals can be generated by a plurality of sources all of which operate during the transmission interval, thus enabling the transmission of increased energy into the medium (viz., the seismic signal power injected into the earth).

Abstract: IMPROVEMENT IN A WEIGHING SCALE                    Abstract of the Disclosure A weighing scale is illustrated having a compensation for correcting the non-linearities of a load supporting spring.    The load support is caused to deflect, and the load spring caused to be put in tension as a weight is put on the load support of the scale.  The load spring has a non-linear response, which is effectively eliminated by the compensator.  The compensator com-prises a frictionless-type rotatable drum which is operatively connected between the load support and the frame of the scale.          The drum is not journalled, but rather, is free to rotate about a vertical plane in response to the deflection of the load support.          The drum has movable weights to adjust its rotational moment, whereby the counter-force upon the load support is caused to be varied and the non-linear response of the spring is caused to be substantially linearized.
