Abstract: A duplex filter cloth for chamber type filters has two initially separate pieces secured together, as by stitching, around circumferential terminal edges of turned-down collar portions of the respective pieces, which portions are closely and smoothly interlapped to provide a barrel neck for the duplex filter cloth. Turning down of the collar portions is accomplished by an elongate conical mandrel of a jig press which operates relative to mandrel-receiving openings in pairs of bed plates, inserted in turn in such jig press, to effectively turn-down circumferential marginal portions of filtrate feed openings of respective flat filter cloth sheets.

Abstract: A blanket formed of heat and flame resistant materials and adapted to be placed adjacent to a structural part to isolate it thermally from other, adjacent structural parts. The blanket is comprised of a layer of insulation material coupled to a layer of fibrous material impregnated with a thermosetting resin. When the blanket is in a desired shape, the resin is cured to render the layer of fibrous material substantially rigid so it can support itself as well as the layer of insulating material coupled to it. Layers of a heat and fire resistant fabric such as glass fabric are placed on opposed sides of the layer of insulating material to keep the insulating material intact. In one application, the blanket is molded in the form of a box-like structure which can at least partially surround a structural part, such as an aircraft engine, to form a fireshield to isolate the engine from adjacent structural parts of an aircraft.

Abstract: The present invention relates to a method for producing a cleansing and wiping cloth, particularly a cloth of low density wefts and warps formed by interwoven 100% count No. 20 rayon yarn which is treated by chemicals. The treatment includes starching the yarn with cassava starch and CMC having the property of suspending contaminant particles, softening the yarn by a mixture of hydrogen peroxide and a softening agent. The fillers may completely fill up the non-crystalline space of the fibers and cling to the surface of the cloth. The cloth is, in turn, pulled by rollers and ironed, and scissored into pieces of proper size. At least six such pieces are stacked together and hemmed around the periphery to form an entity. The structure is further reinforced by stitching, thereby forming a cleansing and wiping cloth which exhibits excellent absorptivity to moisture, which is easy to dry, and which does not retain any contaminant or unpleasant smell.

The second zigzag stitches formed are wider than the first zigzag stitches.

Abstract: The invention relates to a pad for concrete intended to appreciably reduce the setting time of concrete. This pad comprises an essentially water an air tight flexible cover enclosing a heat insulating cushion resting directly over a lower part intended to be laid in contact with the surface of concrete. This lower part is made up of ribbons woven together in the form of a network in such a manner as to have a good mechanical resistance to wear by friction and so as to create a zone between the heat insulating cushion and the surface of the concrete capable of allowing the excess water oozing through the concrete surface to flow only slowly away, thereby avoiding the need of water from an outside source, allowing also the heat resulting from the setting reaction of concrete to accumulate inside the interstices of said network thus to accelerate the setting of the concrete. This pad is particularly useful and efficient during the year's period of cold weather where the setting of concrete is particularly long.

Diving suits formed using such seam construction are stronger, more comfortable, more durable, more aesthetic and leakproof.

Abstract: A method of making patchwork articles includes the steps of drawing the overall pattern of the patchwork article onto a sheet of paper to produce a master drawing which is an overall pattern of visible lines. The master drawing is then reproduced on flexible paper, preferably tracing paper, which is then cut along the visible lines to form individual paper patterns. Each of the paper patterns is used as a guide for cutting a fabric piece which is of the same general shape as the paper pattern but slightly enlarged on all sides to form a border. The borders of each fabric piece are folded over the paper pattern from which the piece was cut and the borders are held to the paper pattern by temporary stitching. The individual fabric pieces are then joined together using the numbers or other indicia on the paper patterns as a guide, so that the joining of the fabric pieces corresponds in overall design to the original overall design as drawn on the paper.

The tubular knit components are preferably knit on a small diameter knitting machine having a reciprocating feed for each of the needles so that the feed reciprocates between a pair of adjacent needles, and is supplied from a creel or other stationary supply.The products made in accordance with the invention are useful for thermal and electrical insulating, gasketing, padding, sealing and similar purposes.The novel method for producing the fabric is diagrammed in FIG. 6.

Abstract: A reactor tube for a high temperature chemical reactor having a precisely controllable porosity comprises a plurality of layers of a fabric of a fibrous refractory material such as carbon or graphite cloth. Difficulties connected with the handling of carbon cloth, which has an extremely high coefficient of friction, are substantially eliminated by winding the cloth on a mandrel to form the reactor tube. After winding, the mandrel is contracted, allowing its removal without damaging the inside surface of the tube. Heating elements for the high temperature chemical reactor are also formed by winding carbon cloth on a mandrel. A preferred embodiment of the reactor contemplates that a plurality of such heating elements be positioned radially outwardly of the reactor tube.

Abstract: An elongated, generally hourglass shaped weight-cushioning device for attachment to the handles of a bowling ball carrying bag has an outer layer of relatively thin vinyl material and a somewhat thicker inner layer of foam padding material. The outer layer has a shape substantially identical to but slightly longer than that of the inner layer. In constructing the device, the layers are superimposed with an end of the first layer being aligned with an end of the second layer. The layers are then simultaneously bent longitudinally and attached by a continuous line of stitches around and adjacent the peripheral edges of the layers in a manner such that, subsequent to the attachment, the peripheral edges of the outer and inner layers are brought into congruent alignment. This imparts a slight longitudinal curvature to the device, the outer layer being curved outwardly of the inner layer.

Abstract: A novel low bulk seam is disclosed for use in paper making machine fabrics, such as dryer felts. The seam is particularly adapted for use with multi-filament yarns which comprise multi-ply fabrics.
