Abstract: A cockroach trap is constructed to attract and kill cockroaches by providing a confined space between nested metal cups and including means for heating the space continuously to a first temperature such as 70.degree. to 90.degree. F. that is attractive to cockroaches and periodically heating to a temperature such as 180.degree. to 200.degree. F. that kills them. The two cups are stacked one inside the other with spacers between the cups. An electrical heating element is disposed circumferentially around the outside of the outer cup to provide the first temperature, and other elements in heat transfer relation with both of the cups providing the second temperature. Attractants such as pheremones, food scraps, or bait, along with water, may be provided at the bottom of the confined space. The inner cup may be readily lifted out to enable removal of dead cockroaches.

Abstract: A thread motion monitoring system wherein the presence or absence of thread motion for discrete threads is detected and signals developed in terms of the failure, non-thread motion, of selected numbers of threads.

Abstract: A storage cabinet for use at manufacturing plants, construction sites, shops, etc. The cabinet is provided with two pairs of opposing storage compartments, vertically arranged for easy access to the stored items, such as tools and other equipment. Lifting pads are secured to the base of the cabinet and extend through the top of the cabinet, and rollers are provided at the bottom of the cabinet. Doors are provided at each of the four sides of the cabinet and are sized and positioned to provide easy access into each compartment.

Abstract: Bonded seams for joining nonwoven, spunbonded polyolefin fabric to itself are prepared by overlapping of edge regions of the fabric with linen sides of the fabric in contact with one another and first applying heat and pressure along a seam line by means of ultrasonic energy and an embossed wheel, giving a lightly bonded strip. The strip is then folded against an adjacent surface, and heat and pressure are applied from the opposite side of the fabric and over the underlying folded-over strip. This procedure in effect merges the bond produced by the second application of heat and pressure with the first bond, giving a strong bond. Cleanroom and protective garments may be fabricated to include such seams, with the side of the seamed fabric that has a remaining cut edge at the seam being disposed on the inside of the garment. Such garments avoid release of microscopic particles such as occurs for stitched seams.
