  • Publication number: 20190334307
    Abstract: A removable device for retaining electrical contacts, having: a rigid element for holding electrical contacts including a plurality of housings that are configured to accept the electrical contacts, the lateral walls of the holding element that are adjacent to the housings having a plurality of openings that each lead into one housing of the plurality of housings of the holding element; and an elastic element for retaining the electrical contacts in the holding element including a plurality of sprung blades that are arranged facing the openings leading into the housings of the rigid holding element so as to retain the electrical contacts in the housings of the holding element. The invention further relates to a soldering method implementing such a device.

  • Publication number: 20070148301
    Abstract: Methods and apparatus for forming preportioned dough units utilizing a forming grid having at least one non-round formation apertures allowing a sheet of dough to be cut so as to substantially eliminate dough waste while providing generally equivalent dough unit portion sizes. The forming grid include one or more formation portions extending from a formation surface. Each formation portion can include an access aperture allowing an ejection member to be slidably inserted through a formation throughbore whereby a proportioned dough unit is ejected from the forming grid. The forming grid can include a peripheral retainer ring to constrain dough as the dough units are formed. The forming grid can be used to cut a dough sheet that has been previously extruded or placed within a packaging tray. Ultrasonic energy can be utilized with the forming grid to further promote cutting and dough release.

  • Patent number: 6531423
    Abstract: The invention relates to a polycrystalline SiC shaped body, which consists of 96% by weight to 99.5% by weight of hard-material grains having a core/shell structure, 0 to 0.1% by weight free carbon, remainder a partially crystalline binder phase; having the following properties: density at least 99.5% of the theoretical density, dark green coloring of ground sections or polished surfaces through characteristic light absorption in the orange spectral region at 1.8 to 2.2 eV, resistivity of at least 107 ohm·cm, and fracture toughness of at least 4.0 MPa.m½, measured using the bridge method.

  • Patent number: 5898008
    Abstract: Dense sintered bodies are provided whicha) comprise from 45 to 99.5 wt % of SiC, the SiC being present in the sintered body as a crystalline first phase, andb) comprise from 0.5 to 55 wt % of a sintering aid, from 0.5 to 30 wt % of which is selected from the group consisting of reaction products of Al.sub.2 O.sub.3 with Y.sub.2 O.sub.3, mixtures of at least one nitrogen-containing aluminum compound with reaction products of Al.sub.2 O.sub.3 with Y.sub.2 O.sub.3, mixtures of at least one rare earth oxide with at least one nitrogen-containing aluminum compound and/or Al.sub.2 O.sub.3, and from 0 to 25 wt % of which is selected from the group of the nitridic silicon compounds, the sintering aid being present in the sintered body as a second phase and optionally further phases, wherein the second phase and optionally the further phases are either amorphous to an extent of more than 10% or are present in amorphous form at the interface to the first phase to a width of at least .gtoreq.5 .ANG.

  • Patent number: 4474637
    Abstract: The invention relates to a machine for making labels of textile material sealable by ultrasonic means and having a delivery section that operates in cycles, and a folding and ironing device for gripping, folding, and ironing the labels which are delivered one behind the other. In order to substantially improve the handling of the labels as they are being sewn in, there is provided after the folding device an ultrasonic sealing device for affixing to the backs of the labels creased folds thereof by means of a fused joint.The invention further relates to a label from textile material for tape sealable by ultrasonic means and having at least one fold creased onto the back thereof, the creased fold being connected to the label across an ultrasonically fused joint, as well as a label with or without a creased fold, the ultrasonically fused joint being formed as a detach-by-ripping fused joint extending across the entire width of the label.

  • Patent number: 4426241
    Abstract: Fabric loops, intended for attachment to articles of clothing for example, are fabricated from a tape the free end of which is sequentially formed into a loops which are permanently closed. To form the loops, a continuous tape is delivered into a track which doubles back on itself whereby the advancing free tape end will overlap a portion of the tape, and the tape will subsequently be cut and the overlapping portions bonded together to complete a loop.
