  • Patent number: T991001
    Abstract: A preformed or prefabricated hot melt sealant strip of essentially any desired length and with any desired cross-sectional configuration is formed by hot extrusion, cooled, and coiled or spooled and may be subsequently used, for example, as a sealing means in the assembly of multiglazed windows, to seal and set automobile windshields and the like. The preferred cross-section is U-shaped if the sealant strip is to be utilized for multiglazed windows but the strip may have a T, E, L shape, or the like, depending on the intended end use. Any hot melt adhesive or sealant composition is suitable as long as it is not too tacky in the cooled state. Some tackiness is acceptable but it requires the use of an abherent or release liner if the strip is to be packaged in such a manner that it is in contact with itself. The sealant strip may then be placed about a dessicant filled spacer element and located between two panes of glass. The sealant may then be activated by subjection to thermal energy to seal the unit.

  • Patent number: 4190932
    Abstract: An arrangement for opening textile fiber bales in which a row of textile fiber bales are broken up by at least two needle tables or rollers placed small distances apart in a row from their bottom side. The distance between the needle points of successive needle tables or rollers are continuously variable. Furthermore, the distance between needle points is changed automatically depending on properties inherent to the textile fiber bales or fiber tufts during operation of the needle table. The actual characteristic value of the detached fiber is compared with a nominal characteristic value, and a different signal is generated and applied as a control on a correcting element. The correcting element varies the distance between the needle points. Disturbance effects are obtained from the textile fiber bale, and this disturbance produces through a control device, an input or set variables for the distance between the needle points. One disturbance effect of the textile fiber bale may be the hardness.

    Abstract: An apparatus for breaking textile fiber bales includes a plurality of spiked breaker members each rotated in a working direction and spaced from one another in the working direction and a support for receiving a series of juxtapositioned bales in the working direction above the breaker members for exposing the underside of the bales to the breaker members. The support comprises a flexible underlay which extends in the working direction for engaging face-to-face the underside of the bales and which is prevented from displacement in the working direction. An arrangement forms an upwardly open chamber of one part of the flexible underlay. The breaker members are accommodated in the chamber for engaging the underside of the bales situated at least in part within the outline of the chamber opening. The chamber and the breaker members are moved as a unit in the working direction along the bales.

  • Patent number: 4190934
    Abstract: A buckling assembly for a safety harness has two parts which can be connected and disconnected from one another. One of the parts has a member which must be actuated to allow connection and disconnection, and once the assembly is connected and closed, actuation of this member is prevented. Additionally, the two parts can only be separated in one relative orientation which will not be reached while the harness is being worn.

  • Patent number: 4190935
    Abstract: A slide fastener stringer includes a stringer tape of a warp-knit structure and a series of discrete or separate fastener elements mounted on and along one longitudinal edge of the stringer tape. The stringer tape has a reinforcing cord laid therein or inserted in an outermost groove between adjacent two wales of the tape, the cord extending warpwise and being thicker than the threads forming the tape fabric. The reinforcing cord is stitched with lock or double locked stitches at intervals spaced along the tape, thereby providing an element-anchoring bead on the tape. A pair of additional threads are preferably interlaced with the stitches and are disposed on the flat surface of the tape.

  • Patent number: 4190936
    Abstract: Apparatus and method are provided for determining the deviation in mask-to-faceplate spacing from a desired spacing during cathode-ray tube construction. The apparatus utilizes the novel method which comprises the steps of sensing the position of the interior surface of a faceplate without a shadow mask being mounted adjacent the faceplate, mounting a shadow mask adjacent the faceplate and sensing the position of a side of the shadow mask opposite the faceplate. The difference in the two second positions minus the shadow mask thickness is the deviation in the desired mask-to-faceplate spacing.
