  • Patent number: 5261409
    Abstract: The puncturing device for blood vessels has an ultrasound probe (20) which permits location, based on the Doppler effect, of the blood vessel (50). By means of a guide duct (13) the puncturing needle (30) can be directed at least approximately coaxially relative to the beam transmitted by the probe (20). Puncturing must be performed in a sterile manner. To this end, according to the invention, the probe is enveloped in a sterile covering, this covering having a sterile coupling member (1) in which a reflector (12) for the ultrasound beam and a needle guide duct (13) are situated. The coupling member (1) may be part of the covering; alternatively, however, it may be designed as an attachment to be placed on the covering. The sterile covering with the coupling member (1), which is intended to be used once only, eliminates the need for time-consuming, repeated gas sterilization of the puncturing device.

  • Patent number: 5251677
    Abstract: The picking device in projectile looms has guide teeth (1) having narrowing zones (20, 20') adapted to receive lubricant transferred from the projectiles (100) to the guide teeth. Because of these narrowing zones and given appropriate shaping no lubricant reaches the guide teeth side surfaces which contact the warp yarns. Soiling of the cloth by lubricant can therefore be obviated. Also, adequate lubrication can be provided so that there is no soiling due to material released by abrasion between the projectile and the guide teeth.

  • Patent number: 5246037
    Abstract: Weft yarn faults encountered during the operation of rapier looms are corrected by correlating the detection of the fault to the angular position of the rotating main shaft of the loom. The loom has a shed with a giver side and a taker side, a giver rapier at the giver side and a taker rapier at the taker side. Position signals are stored in an electronic storage device for weft yarn faults which can occur at predetermined angular positions of the main shaft during operation of the loom. The weft yarn is monitored and a signal is generated when a faulty weft yarn is detected. This signal is compared with the position signals in a logic circuit to thereby determine the nature of the fault. After the nature of the fault has been determined, the faulty weft yarn is appropriately removed and, thereafter, weaving continues.

  • Patent number: 5244164
    Abstract: The yarn brake (1) having electromagnets (12, 12') and a brake lamella (2) has, on that side thereof that is remote from the yarn (3), a segmented layer (5) of soft ferromagnetic material. The layer (5) is effective to strengthen the magnetic attraction. Substantially platelike segments (55, 56) of the layer (5) are disposed in accordance with the operating ranges of the discrete electromagnets (12, 12') and have connections (60, 560) to one another and/or to the brake lamella (2). The connections (60) between the segments (55) are flexible. Because of the segmentation of the attraction-increasing segmented layer (5), the flexibility of the brake lamella (2) remains substantially unimpaired. The yarn brake can be released by electromagnets (12') disposed on one side of the segmented layer (5). By means of a blower (28) having nozzles (29) distributed over the length of the brake gap, fly can be removed from the braking surfaces when the yarn brake (1 ) is released periodically.

  • Patent number: 5241994
    Abstract: A rapier loom has a picking mechanism in which one rapier (a giver rapier) transfers a weft yarn to another rapier (a taker rapier) in mid-shed. Each rapier is oscillated toward and away from one another by a drive and includes a yarn clamp which is actuated by a clamp opener to provide reliable yarn transfer from one rapier to the other. The rapier drives and/or clamp openers are driven by programmed servomotors. In this way, the velocities of the rapiers and/or the interval in which the clamp openers are opened can be adjusted according to the properties of the particular weft yarns used to ensure reliable transfer without damaging the yarn.

  • Patent number: 5230769
    Abstract: A process is provided for the separation of substances by melt crystallization. The organic mixtures which are difficult to crystallize are heated to a temperature sufficient to obtain a melt with the melt then being moved through a three-dimensional crystallization matrix having a large specific area. The melt is slowly cooled over a temperature range so as to achieve a selective crystallization from the supersaturated melt in the carrier matrix. A deposited crystal phase is thereafter melted and separated from the carrier matrix and removed by centrifugation. The carrier matrix may have a crystallization-promoting microstructure surface and may consist of an openpored foam.

  • Patent number: 5228836
    Abstract: The runner for pumping hot reactor liquids includes a runner body which is connected with a shaft portion which transmits a driving torque. An annular insert is disposed between a bearing sleeve projecting from the runner body and the drive shaft portion to define an annular flow path in order to guide an auxiliary flow which, in the case of an injection operation, leads cool reactor liquid to the runner in one direction of flow and, in the case of a leakage operation, leads hot reactor liquid for cooling away from the runner in an opposite direction of flow. A closed cavity is formed between the runner body and the drive shaft portion in a transition zone between the two components so as to reduce the cross-sectional area for the transfer of heat between the runner body and the drive shaft portion. The cavity is formed by a blind bore which has a diameter greater than 30% of the outer diameter of the shaft portion.
