One neck is provided, at the flange side, with an enlarged bore terminating in a shoulder which is substantially parallel to the flange, and a pierceable sealing pad is inserted from the flange side into said enlarged bore, the latter being eventually closed by the pouch wall.

Abstract: In the production of decorated tufted carpet tiles, a tufted carpet web is made by tufting a pile yarn in a substrate, precoating and backing the tufted substrate on the backside, followed by dyeing, imprinting with a pattern, steaming, washing and drying the carpet web, and thereafter by punching or cutting tiles from the carpet web in the process, the carpet web, prior to the dyeing step and preferably after precoating, is heat treated by being exposed to a temperature of 120.degree.-200.degree. C., preferably 140.degree.-170.degree. C., for 1-8 minutes, preferably for 3-5 minutes, while it is freely supported on an auxiliary carrier, and then subjected to cooling to below 50.degree. C.

Abstract: In apparatus for producing a corrugated element, each pressing device for deforming a top web of the corrugated element has a separate guide means which is adjustable relative to a plane extending transversely with respect to the direction of forward feed movement of the webs. Each guide means is secured together with drive transmission for its pressing device to a plate. The plates can be adjusted by adjusting screws on opposite sides of the webs, thereby permitting the pressing devices to be adapted to specific operating conditions.

Abstract: An improved method and apparatus for compacting a composite tape tail which is formed by making a cut along an oblique line across the tape and manipulating first and second compaction means. The cut, however, severs only the tape while it is adhered to the backing but does not sever the backing or subjacent support (which is usually a strip of paper). The backing is then peeled away from the strip at a location between the first compaction means shoe, blade, or pad) and a second compaction means (preferably a roller) and conveys the discarded portion of tape to storage, disposal etc. The first compaction means bears down on the assembly of tape and backing. The second compaction means engages the tape after the peeling away, hence bears down on only the tail. Only one compaction means is used at a time. The second compaction means compactingly engages the tail not later than the arrival of the tail leading edge at said second means by which time the first compacting means has stopped compacting.

Abstract: Method for thermobonding thermoplastic material. A support plate supports sheets of the thermoplastic material, and heat element means is provided adjacent thereto. Pressure plate means mates with the support plate and may include recess means for receiving the heat element means. Melt zone means are formed between the heat element means and the pressure plate means (or the recess means) when they are in mating relationship. The melt zone means serves to confine the melted thermoplastic means to form a good seal by relieving stress between the seal and the seal-material interface. The heat element means and recess means are manufactured as interchangeable dies in different sizes and shapes for different materials. The heat element means may be formed into different shapes, such as a glove for manufacturing gloves.

Abstract: A substantially non-overlapping tightly packed layer of plastic chips is formed and attached to the surface of a substrate by a method in which the chips are dispersed onto the surface of a liquid, flowing from a first location to a second location. The rate of flow of the surface of the liquid is reduced at the second location to cause the chips to pack together in a single-chip-thickness layer. The layer of chips is then removed from the liquid by passing a porous web upward at an angle from below the liquid surface through the chip layer-liquid interface. The chip layer is then transferred to a heat-sensitive transparent adhesive coating on a suitable prepared substrate and secured thereon by means of heat and pressure. A resinous wear layer which is transparent after fusion is then applied.

Abstract: A method for splicing belt ends of an endless belt, as in the field, wherein uniform tension is provided to the reinforcing members such as strands or cables in the spliced section. The respective spaced ends or sections have all belting material removed leaving each end with a laterally extending end section spaced from its adjacent main body section of the belt and interconnected only by the cable. The dressed end sections are overlapped and thence the center section of the overlapped portions are cast into a belt section with cables embedded therein. The laterally extending end sections are cut leaving two uncast sections which are then cast or molded to encapsulate the remaining bare cables to form a continuous belt by such splicing.

Abstract: A cutting tool, preferably in the form of a scalpel, microtome or razor blade is fabricated from single crystal material such as aluminum oxide with a preferential etching process to produce a radius of curvature less than 100 Angstroms on the edge. Depending upon the etchant, the crystallographic orientation of the blank and the resulting different etch rates on blade surfaces, the preferential etching process not only sharpens a preformed edge but also, in one embodiment, produces an opposing edge which meets the sharpened edge at a point, thereby to produce a particularly efficient scalpel blade configuration having two cutting edges converging at a point for plunging and cutting. With respect to the sharpening of the cutting edge, consistent with all other blade forming requirements, the subject blade is made to a maximum sharpness by utilizing a maximum ratio of bevel plane etch rate to edge plane etch rate.

Abstract: An in vivo electrochemical monitoring device is formed by a catheter-like member which terminates in a closed end having a wall with a fixed opening to admit fluid to be tested, such as blood in an artery. An electrochemical sensor, such as an ISFET device for monitoring the concentration of a particular ion in blood, is mounted inside the tube at a fixed location below the opening preferably a larger sensing chamber. An infusion channel in the tube is arranged to flood the sensor with a fluid of known chemical properties so that the sensor output can be calibrated. Under pressure the calibration fluid expels the test fluid out of the tube or chamber via the fixed opening. A method of constructing a suitable chamber on an ISFET wafer is also disclosed.
