Abstract: The meter forms part of a heating system supplied with thermal energy in the form of hot water from a heat generator, and serves to determine the amount of heat supplied to a consumer, for the purpose of appropriately charging the consumer for incurred heating costs. The meter includes a computer, operating on the analog principle, a volumeter and connection elements for connection to signal processing devices. The volumeter is formed by a first tubular body through which the hot water flows to the consumer, and this first tubular body is surrounded coaxially, at a definite radial spacing therefrom, by a second tubular body so that the two tubular bodies define a completely closed annular space. The cooled hot water returns through a return line. The supplied hot water in the first tubular body constitutes a primary medium flowing therethrough, and the completely closed annular space receives a secondary medium which is heated by the primary medium.

A gun which has a recoiling barrel, particularly for armored wheeled half track or full track motor vehicles has a gun body portion with respective outwardly extending bearing pins engaged in respective first and second bearing bushings. A resilient assembly is disposed between each of the pins and its associated bushing and it includes inner and outer radially spaced apart concentric bushing rings with a rubber ring disposed therebetween undetachably interconnecting the outer and inner bushing rings. The rubber ring is advantageously vulcanized to the respective inner and outer rings.

Abstract: A spool carrier, particularly for winding up textile threads and for centering and clamping spools which are made up of deformable material such as a paperboard or stiff multilayer paper comprises at least one two-member group having first and second members which have interengageable wedge-shaped portions, which are mounted on a spool carrier one after the other in an axial direction. The two members are urged into wedging interengagement by a biasing spring so that the outer member is displaced outwardly into engagement with the spool carrier. A coupling rod mounted for axial displacement within the spool carrier is movable against the biasing means to disengage the first and second members so as to release the spool.

Abstract: The device provides for winding much larger yarn packages on each of a pair of vertically spaced yarn winder chucks on one side of a common drive roll and displaceable alternately in respective slots of a front wall of the yarn winder into engagement with the drive roll for winding of yarn packages and bobbins on the chucks. An adjustable length arm is swingably mounted, through an anti-friction bearing, on a motor drive shaft extending through the front wall midway between the chuck slots and outwardly of the retracted positions of the chucks, and a small diameter pulley is rotatably mounted on the free end of the arm. A larger diameter pulley is fixed to the drive shaft, and a belt is trained around both pulleys. A pair of solenoids, having armatures spring biased outwardly, are aligned in opposition and their armatures engage a fin projecting from the pivot end of the arm to bias the arm to a neutral position in which the belt is out of the paths of movement of the chucks.

Abstract: The mechanism provides for winding much larger yarn packages of each of a pair of vertically spaced chucks on one side of a common drive roll and displaceable alternately horizontally into engagement with the drive roll for winding of yarn packages on bobbins on the chucks. A belt is trained around the drive roll and around an adjustably mounted small diameter pulley located between the two chucks. When a package has begun to be wound on a bobbin on one chuck by rotation by the common drive roll, the other chuck is moved inwardly, from a retracted position, past the partially wound package to a standby position in which it is adjacent but out of contact with the belt. As the package nears completion, the standby chuck is engaged with the "soft" part of the belt, between the drive roll and the pulley, and accelerated to bring its peripheral velocity into substantial synchronism with that of the drive roll.

Abstract: A drive roll has an axis of rotation and at least two rotatable chucks are provided, each being adapted to have a yarn package formed thereon. The chucks each have an axial end and are movable into and out of driven engagement with the drive roll. A traversing arrangement traverses a running yarn which is being wound onto one of the chucks, in order to form a yarn package thereon. A yarn transfer arrangement effects automatic transfer of the running yarn from the one chuck upon forming of the yarn package thereon to the empty other chuck while the latter is in driven engagement with the drive roll. This arrangement includes an arm which is mounted on the drive roll to be turnable about the axis of rotation of the latter and which has a free end portion arranged to travel in a path adjacent the axial end of the other chuck and intersecting the axis of rotation of the other chuck while the same is in engagement with the drive roll.

Abstract: A garbage collecting and transport vehicle, includes a chassis supporting a changing container which receives garbage which is picked up by a pivotal garbage can loader arm which is mounted on the chassis so as to be pivotal through an arc to raise the garbage can containing the garbage, and invert the can to dump it into a garbage loader housing which is located on the chassis in front of the changing container. The loader housing includes pickup blade which is pivotally mounted in the garbage loading housing to move it up to the level of a transfer opening which aligns with an inlet opening on the changing container. The closing blade which in one position closes the opening is first moved to a position in which it closes the inlet to the loader housing and, after the garbage is picked up by the pickup blade, it moves back to the transfer opening and pushes the garbage into the changing container.

Abstract: The mechanism is used with a yarn winder having a traverse guide box or housing, a traverse guide and chucks, drive rolls, and control rollers for rotating yarn package supports, such as bobbins or tubes, and provided with a yarn catching device, such as a peripheral groove or hook, adjacent one end of the package supports, with the traverse guide cross-winding yarn packages on the supports. The yarn strung up in the winder, under a tension tending to move the yarn into a traverse guide, is caught in a guide member, while restrained from entering the traverse guide, and the yarn is moved by the guide member into a position aligned with a yarn catching device for catching of the yarn which is then broken or cut. The yarn is then moved in the guide member axially of the package support to wind a few turns therealong as a transfer tail, after which the yarn is released from the guide member to enter the traverse guide for cross-winding to form the yarn package.

Abstract: A machine for winding textile threads, comprises a drive cylinder for driving at least one bobbin holder which is biased against the circumference of the drive cylinder. The bobbin holder is rotatably supported on a receiver which is guided along a horizontal guideway of a bobbin carriage. The receiver is urged by weight in a direction to cause engagement of the bobbin holder which receives the ball against the periphery of the drive cylinder. The receiver is movable continuously along the horizontal guide with an increase of ball volume as the winding proceeds. A swivel guide bar is pivotally mounted adjacent the guide and it is inclined relative to the horizontal and is pivotally movable in one direction and performs the slight pivotal movement during the horizontal displacement of the receiver. The receiver has a feeler roller in operative connection with the swivel guide bar and there is a second stationary feeler located adjacent the guide bar which is actuatable by the pivotal movement of the guide bar.

Abstract: A device for the axial spacing of spool tubes along a common spool carrier, comprising a rotatable cylindrical spool carrier which has a periphery with a recess therein which accommodates a device which permits passage of a first spool tube over the carrier to a position at which the first spool tube abuts against a stop. The device thereafter projects outwardly from the periphery of the spool carrier behind the first spool tube so as to prevent the second spool tube placed on the carrier from moving further toward the first spool tube and thereby maintains a spacing between the two spool tubes. The spool carrier also carries a recess in the periphery thereof at the location between the two spool tubes which comprises a means for catching the thread which is to be wound.

Abstract: A device for controlling thread spooling drives in which a bobbin package and its associated carrier roller are frictionally driven by a motor driven drive roller comprises a rotatable carrier roller shaft having a conical portion formed thereon bevelled radially outwardly and arranged substantially in alignment with an end conical formation on a bobbin carrier roller. The rotatable motion is transmitted from the rotatable carrier roller shaft to the bobbin carrier roller by engagement of a clutch cone having a double cone portion between the conical end portion of the bobbin carrier roller and the conical portion of the carrier roller shaft. The engagement and disengagement is effected by a fluid control device and the whole carrier shaft drive is supported in a housing for movement toward and away from the drive roller.

Abstract: A method for monitoring and regulating electrical resistance welding by comparing the actual values obtained by integrating measured values of the welding electrodes with desired valued limits obtained by test welding operations in the form of voltage and current parameters. These parameters are integrated in accordance with the formula ##EQU1## WHEREIN Y IS OTHER THAN UNITY AND IS SELECTED SO THAT THE INFLUENCE OF THE RESISTANCE R on the actual, measured value is at least equivalent to the influence of the current I and/or the welding time t, in the above formula, on the measured value. The resultant weld value is then fed to a comparison circuit which contains the upper and lower limits obtained by the test welding. If these limits are exceeded the power to the welding apparatus is automatically disconnected.
