Abstract: ABSTRACT OF THE DISCLOSURE        A device for providing a gas-tight connection between the hollow shaft of a rotatably mounted reaction drum and a stationary feed or return line.  Achieving a gas-tight connection bdtween the hollow shaft of a rotatably mounted reaction drum and a stationary feed or return line has hitherto not only presented considerable difficulties but has also not as yet been satisfactorily accomplished.  These difficulties are caused not only by the fact that the reaction drum is under positive or negative pressure, but mainly by the fact that when the said drum is in operation, the hollow shaft lifts axially and also radially off the stationary feed or return line, to a greater or lesser degree, and moves away from it.          It is true that, in the case of ball/roller bearings, sealing devices are known for one-piece shafts which provide a more or less satisfactory gas-tight connection between the shaft mounting and the housing of a container.  However, such sealing devices are not only of relatively complex design, but are also completely unsuitable for providing a gas-tight joint between the hollow shaft of a rotatably mounted reaction drum and a stationary feed or return line.  According to the invention, however, a reliable and particularly effective gas-tight joint between the hollow shaft of a rotatably mounted reaction drum and a stationary feed or return line is obtained in a particularly simple manner, in that an annular disc is arranged at the joint, preferably at the hollow shaft, the said disc being enclosed by a cross sectionally U-shaped housing secured to the feed or return line; in that the said housing contains at least one sealing ring which is pressed against the said annular disc, the said sealing ring communicating with the said housing through bellows-like casings, spaced radially from each other; and in that lines for the supply of gaseous or liquid pressure media to the space enclosed by the bellows-like casings are connected to the housing.  These arrangements according to the invention make it possible, very advantageously, to vary the pressure with which the sealing ring is applied to the annular disc in an optimal manner, i.e. not only completely independently of the pressure obtaining in the reaction drum, but also completely independently of the type of gaseous or liquid sealing medium supplied.  This not only provides very advantageously a gas-tight connection, independent of any external factors, between the sealing ring and the housing, but also, and completely independently of any wear in the sealing ring, a safe and reliable gas-tight connection between the hollow shaft of the rotatably mounted reaction drum and the stationary feed or return line, if the said hollow shaft of the  rotatably mounted reaction drum lifts, in relation to the stationary feed or return line, in the axial or radial direction, off the said feed or return line, or moves away from it.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention provides an agricultural baler including a bale case, a feed platform adjacent the bale case, a first feeder mechanism which feeds crop material across the feed platform toward the bale case, and a second feeder mechanism which feeds crop material from the feed platform into the bale case.  The second feeder mechanism includes feeder elements rotatable about a first axis and about a second axis offset relative to the first axis such that the feeder elements move in a predetermined path which is generally "apple shaped".          A drive mechanism connected to the feeder elements causes them to rotate around the first axis in one direction while they are being rotated around the second axis in the opposite direction.  This invention provides for an improvement over the balers known in the prior art, as it prevents undesirable vibration in the baler by the even loading of a bale case, obtained with the particular path of movement provided.  As well the tendency to overload the baler is substantially reduced by the improvements in the present invention.  A relatively low profile baler is obtained according to this invention, unlike balers known in the prior art, which because of the type of second feeder mechanism used therein, usually result in a baler of excessive overall height.

Abstract: Non-Contacting Workpiece Gauging System Abstract , A system for finding the position of a workpiece surface relative to a reference through non-contact gauging.  The system uses a radiant energy beam pro-jected such that an illuminated spot moves along the workpiece surface with movement of that surface relative to the reference along a measurement direction.  An array-type image detector, which is out of physica1 contact with the workpiece, detects the illumination at each of a number of small areas of the workpiece surface and generates signals representative of the detected illumination.  These signals are converted into a test signal which is a function of the difference in overall illumination between larger areas of the workpiece sur-face.  A reference signal is produced and stored for two known positions of a workpiece surface.  The test signal and the reference signal are combined with each other to produce a measurement signal indicative of the position of the workpiece surface relative to the reference.

Abstract: ABSTRACT The invention relates to a method and a device to produce several circumferentially spaced labelling strips of polyethylene on the surface of steel pipes sheathed with polyethylene, the sheathing being formed by simultaneous extrusion of a tubular foil of ethylene copolymer serving as contact adhesive, and of a tubular polyethylene foil lying over it, using an extruder head with two ring channels.  In order to be able to apply coloured labelling strips onto the sheathing in the longitudinal direction during extruding of the tubular contact adhesive and sheath foil, it is proposed that for the sheath foil and the labelling strips polyethylene with certain melting indexes are used, and that the extruder pressure for the sheath foil or the labelling strips is kept at a pressure difference between 10 and 50 bar.  The device is essentially characterized by the specific arrangement of the outlet openings for the labelling polyethylene on the outer ring slot.

Abstract: TELEPHONE CALL PROGRESS TONE AND   ANSWER IDENTIFICATION CIRCUIT                ABSTRACT OF THE DISCLOSURE          Disclosed is a call progress tone detection circuit for determining whether an incoming telephone signal is a call progress tone and for identifying such call progress tone.          The circuit includes an envelope detector for receiving a signal and for developing an envelope signal representative of the envelope of the received signal.  The call progress tone detection circuit extracts the low frequency envelope of the received signal and examines its period.  These period measure-ments are accumulated and then evaluated.  If the envelope period is not reasonably constant over a standard measurement interval, then the call progress tone detection circuit can conclude that the received signal is voice.  However, if the envelope period is regular, then the call progress tone detection circuit according to the preferred embodiment of the present invention will compare the detected envelope period and other timing parameters of the signal to known periods and corresponding parameters for signals used by the various telephone systems in current use.  If there is a match between the detected parameters, then the call progress tone detection circuit identifies the call progress tone for further use by the automatic telephone caller.
