Abstract: An improved dryer fabric, woven entirely from monofilament plastic polymeric warp and weft strands, having a lower permeability to air flow and lower modulus of elasticity than normal fabrics, wherein at least the warp strands are flattened in cross-section, with the long axis of the flattened section extending parallel to the plane of the fabric and wherein the weft strands may be shaped so as to more or less conform to the horizontally directed passages of the mesh naturally formed by the woven warp strands and may also be relatively more malleable than the warp strands so that under stress they can adapt to conform to the shape of mesh interstices thereby to restrict these and still further reduce the permeability.

Abstract: A profiling system comprising a profile member having a profile guide element. The profile member is displaceable along a first straight axis. A working head is fixedly secured relative to a work support surface and spaced relative to the profile member. The working head and the support surface are mounted on a head support frame displaceable along a second straight axis extending transversely to the first axis. Support members are secured relative to the profile member and displaceable therewith to retain and displace a material to be worked on by the head. A follower element is fixedly secured to the head support frame and displaceably engaged with the profile guide element. The head support frame is displaced along the second axis in response to angular deviations from the first straight axis as defined by a path delineated by the profile guide element as the guide element is drivingly displaced along the first axis.

The member is generally solid and includes, in accordance with the invention, a cavity extending inwardly from at least one end of the member and terminating in a bottom surface of the cavity. A plurality of holes extend inwardly from the bottom surface of the cavity and are disposed in circular arrangement around the bottom surface of the cavity and adjacent to the periphery of the member. A ring member is disposed in the cavity, the bottom surface of the ring member being spaced from the bottom surface of the cavity to define a chamber therebetween. An opening extends through the ring member from the top surface to the bottom surface thereof, and valve means are inserted in the opening to permit the insertion of gas under pressure into the chamber and into the holes.

Abstract: An automatic weighing and bagging machine and method for holding and opening a first bag of a plurality of juxtaposed bags held in the machine in a manner whereby the first bag may be filled with a weighed product and released from the plurality of bags. The bags are of the type having an extended tab secured to a portion thereof and extending above a mouth opening of the bag. The machine comprises a holding device for engaging at least a portion of the extended tab of the first bag. A retractor member is also provided for opening the mouth opening of the first bag by pulling a side wall portion of the first bag opposite to the engaged portion of the tab and away from the engaged tab. The retractor member also clamps the side wall portion to hold the bag in an open position whereby the bag is held from opposed sides for filling the bag with the weighed product. A container is provided to hold and weigh the product to be bagged.

Abstract: A method and apparatus are provided for the extrusion of a thermoplastic material in modified form in which the thermoplastic material is introduced into the barrel of a screw extruder, and is heated and forced through the barrel: the material is passed through valve means which together with the temperature of the material is effective to produce a melt transition in the material at a predetermined point and to thoroughly mix the material; subsequently, the material is forced into a low pressure zone in the barrel where a modifying agent is introduced into the material; the resultant mass is forced out of the low pressure zone, and is passed through a mixing means effective to intensify the dispersion of the modifying agent in the mass, the mass is extruded and the extruded material collected.

Abstract: Present parameter value indicators are wasteful of space and expense and have parallax error if viewed at an angle. This invention is a vertical strip bargraph comprising separately illuminated squares of different colors to indicate values of the parameter without parallax error and economical of space and expense.

Abstract: The invention relates to a heating element for a heated chair which can be used as a covering material for the heated chair or which can be laid under the covering material or which can be draped over an ordinary chair to convert it to a heated chair. In accordance with the invention, the heating element has a glass fibre fabric layer made of intermixed glass fibre strands. An electrical resistance wire which consists of a core of glass fibre strands with a resistive wire wound around it, forms an undulating pattern in the glass fibre fabric layer, and top and bottom layers of thermoplastic material are heat fused or adhesively laminated to the glass fibre fabric layer. A metallic foil layer is applied to the side of the bottom layer which is remote from the glass fibre fabric layer. The heating element also includes a control for controlling the power delivered to the resistance wire. The said control is a simple dual proportional control which regulates the energy usage of the heating element.

Abstract: A form pan section comprising a top wall and opposed side walls depending from a respective opposed side of the top wall. A support flange is provided along a free edge of each of the side walls. The support flange has a load supporting bearing section. Means is provided in each of the support flanges to secure the flange to supporting framework. Connection means is provided inwardly of the top wall and side walls to interconnect the pan section to another pan section. A form pan is constructed of at least two end pan sections having the above-described characteristics.

Abstract: A self-extruding fastener having a head provided with a cross groove, a stem having two screw threads and a tapering portion terminating at a sharp pointed forward end adapted to form a guide opening in a thin sheet of metal. A third screw thread generates in a position midway between said two screw threads and in a portion where the stem ends and the tapering portion begins, and extends to the pointed forward end, while the two screw threads disappear in the tapering portion. Therefore, the self-extruding fastener according to the invention comprises three sections, that is, two screw thread section, three screw thread section and one screw thread section.

Abstract: A readily dismountable frame for mounting a container and cover under a supply shelf. The frame is suspended between spaced-apart rails depending from the shelf. One end of the frame is provided with fixed hooks to engage a first rail and the other with retractable spring-loaded catches which engage a second rail spaced from the first.
