Abstract: Increasingly greater requirements as concerns mechanical strength and gas tightness are placed upon the connection between the sabot tail or rear portion and the sabot jacket of a sabot projectile. To improve such connection the invention provides a circumferential groove at the sabot tail or rear portion, this circumferential groove having side walls extending essentially parallel to one another and inclined forwardly with respect to the lengthwise axis of the projectile at an angle of about 75.degree.. The rear end of the sabot jacket protrudes into such circumferential groove.

Abstract: The method of, and apparatus for, producing a yarn uses a friction spinning device comprising a perforated first friction spinning drum and a second friction spinning drum which can also be perforated. Two fiber feed passages project to the first friction spinning drum and are each supplied by opening assemblies which individualize or individually separate the fibers. The fibers are transported toward the first friction spinning drum using a feed air stream in the fiber feed passages. This feed air stream is produced by the first friction spinning drum which is maintained under sub-pressure. Advantageously, the fiber double-feed to the friction spinning drum permits supplying two different fiber types to the same yarn end. Also, different inclinations of the fibers at the friction spinning drum can be obtained by different inclinations of the fiber feed passages in order to produce yarns of different character.

Abstract: Into a material based on a caoutchouc-type or caoutchouc-containing mixture for producing hard rubber, there is incorporated a pre-mix containing high-strength organic fibers and a liquid hardenable plastic material. The high-strength and temperature resistant material thus obtained is particularly suitable for the attenuation of noise in combustion engines when heavy-weight fillers are also added to such material. Engine components like, for example, valve covers, timing gear covers and oil pans can be manufactured from this material.

Abstract: A cleaning apparatus or arrangement for cleaning a set of flats of a revolving flats card has a pivotable brush for engaging the strips or strip accumulations of the flats and a suction device arranged behind or downstream of the pivotable brush considered with respect to the direction of movement of the flats. According to the invention, a suction nozzle of the suction device is reciprocable over the length or transverse extent of the flats. By means of this arrangement, there is obtained a suction action affording a great cleaning or stripping effect at the flats despite a considerable reduction in the energy required to create the suction action in comparison with heretofore known flat cleaning or stripper arrangements.

Abstract: The front wall and support arrangement is shaped as a stiff support structure extending across the entire machine width above a slice chamber. The support structure is deformed due to its inherent weight and because of the pressures and temperatures prevailing in the slice chamber. To counteract these deformation effects the support structure is supported by a support carrier of about the same length as the support structure. To attain a substantially lower structural height, the support carrier is arranged relative to the support structure such that an intermediate space prevails between the lower wall of the support structure and the support carrier. This intermediate space accommodates force-generating support elements. Each of the force-generating support elements is provided for only a portion of the surface or area to be supported in the intermediate space.

Abstract: The printed products arriving in an imbricated formation are wound up into wound product packages or coils each having a substantially horizontally disposed longitudinal axis. These wound products packages possess a predetermined size and an inherent stability which permit them to be transported and intermediately stored such that their longitudinal axes extend substantially vertically without the wound product packages disintegrating or unraveling. After forming the wound product packages they are transferred from a standing position into a reclining or reposing position by means of a package turning device. In this reclining or reposing position the longitudinal axes of the wound product packages extend substantially vertically. These wound product packages are supported only at their circumference or are only held at their winding cores and are not supported in any further manner.

Abstract: A method and arrangement for transmitting data in a data loop comprising at least two stations and at least one of which is an overriding master station in which a transmission frame for the data to be transmitted is generated for transmission through all successive stations. Each transmission frame is generated with a predetermined constant number of clock cycles and contains exclusively the data to be transmitted from one station to one or more others and is devoid of protocol signals, especially devoid of address signals. Each transmission frame is immediately followed by the beginning of a further identical transmission frame containing the next data to be transmitted, if any. Time slots, preferably mutually equally great time slots, in the transmission frame are permanently or temporally modifiably allocated to the individual stations for information or data transfer before entering each transmission frame into the data loop.

Abstract: The winding core mounted to be rotatable and removable in a mobile storage unit, is placed into rotation by means of a drive roll which engages at the outer surface or circumference of the widing core or, as the case may be, the wound product package forming thereupon. In the mobile storage unit there is likewise removably arranged a winding band spool or reel which is also driven at its outer surface or circumference. For this purpose there is likewise provided a driven drive roll. By virtue of such circumferential drives for the winding core and, as the case may be, the wound product package, and equally the winding band spool or reel the mobile storage units can be of simple construction. This also enables the mounting or support arrangement for the winding core and the mounting or support arrangement for the winding band spool or reel to be structured such that the winding core and the winding band spool can be easily removed from the related mobile storage unit.

Abstract: The working apparatus, useful as a cleaning apparatus for textile machines, comprises a mobile servicing or working unit possessing a ventilator cooperating with air guide elements and operates in cleaning zones located at these textile machines. The servicing unit is movable on a track or rails. A stationary drive motor provides the relatively high power drive for the travel motion of the servicing unit along the track and for the ventilator by means of an endless belt trained over transmission members arranged at the servicing unit. These transmission members each contain different size coaxially arranged pulleys. By changing the position of one strand or run of the belt from a smaller size to a larger size pulley and vice-versa, the direction of movement of the travelling servicing unit can be selectively reversed. The movement of the servicing unit is monitored by a control device arranged at the servicing unit with the aid of terminal or limit switches and sensors.

Abstract: The embroidering frame of the shuttle embroidering machine comprises cloth beams drivable via drive means. The cloth beams coact in pairs to receive between each such pair a respective material web. These material webs are superimposed in the frame plane and at each material web there engages at each longitudinal edge of the web material a rod-shaped temple or spreader. The upper and lower cloth beams both for the upper and lower material webs are each in selective driving connection by a respective endless belt of the drive means with the driving shaft of an associated geared motor of the drive means and which is carried by the embroidering frame. A belt tensioning device which is reversibly switchable with the rotation direction of the associated geared motor is used. The control circuit of the geared motors contains switching means for the selective separate or synchronous operation of the two geared motors.

Abstract: This device prevents individual components of a load from being thrown off during halting of a conveying vehicle at a high rate of deceleration. A blocking device for the suspension of the caster which instantly assumes a front position as viewed in the direction of travel, prevents the vehicle from forwardly and downwardly dipping about the axle of the center-mounted drive wheels. The blocking device automatically adjusts itself corresponding to the direction of motion. A sliding stop vertically displaceably mounted on a pivotable part of a caster arrangement and a stop component fixedly mounted on the vehicle body cooperate to block the suspension of this front caster when the front caster experiences a predetermined degree of suspension displacement. At the caster instantly assuming the rear position, the stop component and the sliding stop are positioned at 180.degree. to one another, thus precluding inadvertent engagement and permitting full suspension displacement.

Abstract: A machine for winding thread comprising an operating region in which thread packages are formed and retained, if necessary, to await doffing thereof. At least one chuck is provided in the operating region, which is rotatable about a longitudinal chuck axis for winding of thread into a package thereon and has a predetermined doffing position in the operating region. An enclosure having at least one access door is provided for the operating region, the door being movable relative to the enclosure for exposing an access opening to said doffing position while the enclosure hinders access to other portions of the operating region.

Abstract: The venting apparatus for liquid-filled systems permits accumulated air to automatically escape from the system. The venting apparatus comprises a bottom member with an internal bore containing a spring-loaded plunger movable to open and close an air venting channel, and a top member with a protective cap.

Abstract: The target tracking system has high tracking reliability at small servo load and comprises a plural number of groups of target sensors having tracking signal travelling times which vary from one group to the other and defining respective lines of sight, a servo system causing the lines of sight to track the target, a target estimator for estimating the movement of the target, a servo estimator for estimating the movement of the servo system, and a regulator which identically controls the servo system and the servo estimator such that the vectorial difference between the estimate of the target movement and the estimate of the servo movement is caused to approach zero. During the target tracking operation, vectorial target deviation signals which are generated by groups of angle sensors, are processed by multipliers using respective matrices in order to produce related combined target deviation signals.

Abstract: The cleaning apparatus for cleaning the set of flats of a revolving flats card has a shaft supported by a carrier. The shaft is pivotable about the lengthwise axis of the shaft together with a cleaning brush fixedly mounted on the shaft and extending over the width of the card. In accordance with the invention, the carrier is movably mounted on the card framework in such a manner that at the flats cleaning position the spacing of the path of movement of the cleaning brush from the set of flats is variable, whereby during the pivotal movement of the cleaning brush effecting cleaning of the flats clothing the spacing of the path of movement of the cleaning brush from the set of flats at the flats cleaning position is smaller than during the return movement of the cleaning brush. The cleaning apparatus affords the advantage of improved cleaning of the flats clothing.

Abstract: The industrial truck or vehicle comprises a support body or member supporting an elevatable platform. The support body is supported and guided on both ends by a respective transverse pivot joint of a respective driving module or unit. The width of the support body and the platform is narrower than the width of the two driving units. This narrowing or reduction in width of the industrial vehicle ensures that the complete platform region on both longitudinal sides of the industrial vehicle is manually accessible despite providing good lateral vehicle stability. Furthermore, the torsional elasticity of the support body is increased such that the support body in combination with the transverse pivot joints provide sufficient travel surface adhesion or floor traction of all drive wheels and support or free-running wheels even over irregular or uneven travel surfaces.

The preparation chamber flow communicates with a pressure-tight transition with at least one storage chamber for plasticized polymer. The storage chamber opens into at least one mold cavity filling conduit for charging a mold with molding mass. The device also comprises a drive mechanism for translatory-relative motion of the preparation chamber and the mold cavity filling conduit. The preparation chamber has at least one prolongation.

Abstract: A space surveillance apparatus includes at least one source of sonic radiation driven by a driver circuit as well as a processing or evaluation circuit. Upon movement of an object, or presence of a foreign object within a monitored space, the processing circuit triggers an alarm signal. Each sonic source defines the volume of its own monitored space, according to the equation:L=D.sup.2 /(4.lambda.),wherein:L=Length of main direction of radiation of the monitored space;D=Diameter of diaphragm of sonic source; and.lambda.=Wavelength of acoustic wave.The driver circuit drives the sonic source either in continuous mode, or in pulsed mode, and either at a constant wavelength or at a variable wavelength, i.e. in frequency modulation.

Abstract: A parabolically-shaped reflector antenna particularly intended for space vehicle applications, can be transported into outer space in a folded state. There it is inflated by means of a gaseous agent, such as a gas compound or gaseous medium, which is transported with the space vehicle. The antenna reflector and an antenna radome form an inflatable cavity which is stabilized by a rigidizing torus. The covering material of the antenna reflector, the antenna radome and the rigidizing torus comprise a resin-impregnated layer of fabric. After inflation in outer space, the reflector antenna is aligned such that it will be substantially uniformly heated by the sun for substantially uniform polymerization of the resin impregnant. After polymerization, the reflector antenna requires no gas pressure to keep its shape.
