Patent PT-80504-A (PT)
Title: Waistband interlining
IPC: A41F9/00
Filed: 1985-05-21
Abstract: Waistband interlinings are made by weaving or knitting a fabric (10) having warp threads (1) and weft threads (2) of a thermoplastics material, and cutting the fabric along lines parallel to the warp threads, wherein the fabric is cut by passing it between a stationary pressing element (14) and the horn (13) of an ultrasonic generator, such that the weft threads are melted as they pass between the pressing element and the horn and are caused to fuse into adjacent weft threads to form a continuous edge (3) along the length of the cut fabric. The continuous edge may be reinforced by introducing an ancillary thermoplastics thread between the pressing element (14) and the horn (13). This ancillary thread also melts and fuses to the molten weft thread ends.

Patent PT-83690-A (PT)
IPC: F16B12/20
Filed: 1986-11-06
Abstract: A fitting for connecting two structural components. The fitting includes a locking device mounted on the first structural component and a support device mounted on the second structural component. A rotary member in the support device defines circumferentially extending conical surface against which the front end of the locking device is pressed when the two fitting devices are connected. The force exerted by the front end of the locking device causes the rotary member to be turned. The rotary member has a helical end face which is initially outside of the range of travel of the locking device. Upon turning of the rotary member, the helical end face comes into engagement with a countersurface of the locking device. The resulting connection can only be released by means of a tool. The structural components are pressed tightly together by a further turning of the rotary member. A piece of furniture composed of several structural components can be initially connected without the aid of a tool and can subsequently be tightened after the piece of furniture has been assembled. The fitting makes possible the connection of structural components where the tolerances in assembling the fitting devices are inaccurate or have been exceeded.

Title: Barrier for containing an oil slick on a liquid surface
IPC: E02B15/06
Filed: 1991-04-17
Abstract: Oil transportation by sea causes frequent spills which adversely affect the planet's ecological health and equilibrium. Every year, somewhere around the world, there is a major spill (of the order of 30,000 tonnes). Spills of 30,000 tonnes occur approximately 12 times a year. It would be appropriate for oil carriers, especially large oil carriers, to have means available which are capable of containing the spilt oil or, alternatively, for such means to be available at points close to the routes followed by these vessels, from where any request for assistance at a spill could be attended to rapidly so as to prevent, as far as possible, the dispersal of oil over the sea surface and, if appropriate, to save beaches in the vicinity from the slicks resulting therefrom. The present text describes some means for containing oil split on a liquid surface, particularly the sea. These means are lightweight but capable of acting effectively, at least for the time needed to set up oil- collection equipment at the site and to carry out this collection. They consist essentially of a barrier for containing the oil on the sea surface, consisting of floating cells and respective vertical positioning ballast, which is easy to store, in combination with various types of equipment for placing the barrier around the aforesaid slick. <IMAGE>
