Abstract: A yarn guide member is driven by an entrainment member in a predetermined direction of movement of a belt run of a belt with which there is connected the entrainment member. In a stroke reversal zone the entrainment member is reversed in its movement by the belt moving around a reversing roller and there is thus released the yarn guide member from entraining engagement by the entrainment member. The yarn guide member, while then in so-to-speak free flight, strikes a housing wall operative as an impact wall. The yarn guide member thus changes its traversing direction. After having impacted the impact wall the yarn guide member returns to the entrainment vicinity of the entrainment member which in the meantime has begun its movement along the belt run now located opposite to the first mentioned belt run as the entrainment member rotates around the reversing roller.

Abstract: In order to effect a controllable change in the production of a fiber-processing machine there is changed the working width of the fiber-processing machine.

Abstract: A high pressure evaporation vessel which is operated at a predeterminate pressure above atmospheric pressure, is connected to a low pressure expansion vessel which is operated at a predeterminate pressure below the pressure prevailing in the high pressure evaporation vessel, through a U-shaped siphon tube. The U-shaped siphon tube contains a liquid column absorbing the pressure difference existing between the high pressure evaporation vessel and the low pressure expansion vessel.

Abstract: The slubbing stopping device comprises a movable part having a magnet and a fixed part having a magnet. One of these magnets is an electromagnet and the other a permanent magnet. The movable and fixed parts can assume an operating position in readiness for clamping the elongate or rope-like fiber material which may be constituted by a silver, roving or slubbing or the like. These movable and fixed parts, when in the operating position, are connected by the magnetic field of the permanent magnet. An electrical energy supply delivers electrical energy to the electromagnet so that the movable and fixed parts can be separated from one another and the movable part assumes a slubbing clamping position. The electrical energy supply powers the electromagnet such that the permanent magnet and the electromagnet, which previously adhered to one another by magnetic attraction, are repelled so as to separate the permanent magnet and electromagnet from one another.

Abstract: The method of dispersing a material containing waste paper by means of a dispersion apparatus and a dewatering machine, renders possible performing the material dispersion operation at essentially constant specific dispersion work even when encountering fluctuations of the raw material to be dispersed and of the dispersing process itself. For this purpose there is provided a regulating system which, with the aid of measured values or magnitudes derived from the dispersing process and predeterminate processing relationships, controls the addition of diluting water to the material to be dispersed at a location upstream of the dispersion apparatus.

Abstract: To order to positively lock or arrest an adjusted position at a mechanical device, for instance the elevation position at a firing device, with negligible play, wherein there is fixed the position set by a hand wheel serving for adjustment of the elevation position of the firing device, there is provided a locking or arresting apparatus comprising a clamping device arranged at a stationary part or housing of the firing device. The clamping device comprises two jaw members. By means of the clamping device, following setting of the desired position, such as the elevation position of the firing device, a ring member fixedly connected with the rotatably mounted hand wheel can be clamped between both clamping jaw members by the clamping device. In this way, the ring member can be positively arrested or fixed in position. The locking or arresting apparatus has many fields of application for all types of mechanical devices of different construction.

C. to about 1,070.degree. C.

Abstract: The horizontally mounted rotational bearing arrangement for high speeds of rotation is mounted in a casing in two radial rolling bearings. Each radial rolling bearing comprises rolling members guided by an associated cage, and further comprises a groove provided at the shaft and operative as an inner race, as well as an outer race. A respective slinger ring is disposed between each radial rolling bearing and associated cover plate. An impingement surface extends around the associated slinger ring and is in alignment with an operative edge of such slinger ring. This impingement surface is effective for returning lubricant to the rolling members of the associated radial rolling bearing. The cage of each radial rolling bearing is constructed such that by virtue of its movement in operation, the lubricant is conveyed to the rolling members of the associated radial rolling bearing.

At each of the adjustment motors there can be individually set or adjusted during an adjusting operation prior to starting the adjustment motors the momentarily desired thrust speed and the momentarily desired thrust distance or travel for the respective adjusting element. All adjustment motors are simultaneously started and simultaneously stopped subsequent to reaching the desired position or location of the diaphragm blade.

Abstract: The dud de-arming device serves to de-arm a fuze of a projectile which has remained lying on the ground or the place where it landed as a dud in order to prevent the discovered dud from still exploding when touched or moved. As to spinning projectiles the dud de-arming device should de-arm the fuze after disappearance of the projectile spin and for spinless projectiles the dud de-arming device should de-arm the fuze after a certain time following the impact deceleration of the spinless projectile. The dud de-arming device comprises a rotor which can be rotated by spring force. This rotor can assume an armed or live position due to the projectile spin or by virtue of the firing acceleration. Upon disappearance of the projectile spin or by virtue of the impact deceleration the rotor should assume a de-armed or safety position.

Abstract: In the case of weapon barrels which are only secured at one of their ends at the weapon housing during firing of the weapon there occurs, particularly during series firing, bending vibrations or oscillations which impair the hit probability of the fired projectiles.

Abstract: The bleaching chemicals are added to the pulp immediately after heating of the raw pulp thickened to more than 20% by weight and immediately prior to a dispersing process. This is carried out in a high-speed, high-efficiency disperser, where the heated, thickened pulp is forced through a plurality of narrow slits in a disperser lining and is exposed to strong shearing, impact and kneading stresses. In this way, the dispersing process is reduced to a time period less than 3 seconds, preferably about 1 second or less. As a result, the total time required for reductive bleaching is reduced to less than 15 seconds and no further measures are required for displacing and excluding air from the system. The method can also be advantageously used with oxidative bleaching at reduced reaction time requirements. A high dispersing temperature in the region of 40.degree. C. to 110.degree. C., preferably about 95.degree. C.

Abstract: In order to adaptively determine the original pulse widths of individual pulses of the pulse signal, there are measured the pulse widths of the distorted pulses. A predetermined number of threshold values is preset for such measured pulse widths. The preset threshold values define classes of pulse widths intended to contain pulse widths of pulses which originally had the same pulse widths. The matching between the measured pulse widths and the preset threshold values is improved by means of a statistical evaluation of the measured pulse widths. The apparatus for carrying out the aforementioned method comprises a unit or circuit for measuring the pulse widths of the individual pulses, a unit or circuit for statistically evaluating the measured pulse widths and a unit or circuit for processing the measured pulse widths.
