Abstract: Material, such as natural ground and precipitated calcium carbonate, when modified by surface-treatment with a cationic polymer, has been discovered to be highly effective as a filler material in the making of paper. Utilization of this type of filler material greatly improves the papermaking process by reducing the usage of wet end sizing agent, improving opacity, improving filler retention in the furnish, and causing better drainage on the papermachine, all of which result in the production of a high quality paper having excellent opacity and tensile strength characteristics. The nature of the polymer-modified filler material, the process for its preparation and the method of its use in papermaking are disclosed.

Abstract: A two component binder system comprising a highly dispersible, high specific surface area precipitated calcium carbonate (colloidal PCC) and a cationic starch, especially a cationic potato starch, for improving filler retention, opacity and strength during papermaking.

Abstract: This invention concerns a process for preparing non-woven webs having a very soft hand and a high tensile strength. The process involved includes print bonding a non-woven web with a formaldehyde-free binder having a glass transition temperature of about 5.degree. C. to about 33.degree. C., then drying, curing and then calendering the non-woven web. The resultant non-woven web has a cross dimensional water wet tensile strength of at least 150 g/in and has a softness value of at least as soft as thermally bonded polypropylene. The invention is also concerned with a product produced by the above process.

Abstract: A phase modulated DC-to-AC or a DC-to-DC power converter utilizes input terminals connected to a source of power and output terminals connected to a suitable load. The transfer of power between the power source and the load or from the load back to the power source is accomplished by electronic switching that is phase displaced controlled in all four quadrants.

Abstract: This invention concerns a nonwoven fabric particularly adapted for use as a diaper coverstock. The fabric consists essentially of fibers and a binder wherein at least 50%, by weight, of the fibers are hydrophobic fibers. The binder comprises a water insoluble, hydrophobic, emulsion copolymer of ethylenically unsaturated monomers comprising (A) 1 to 8% by weight of a monoethylenically unsaturated carboxylic acid, or a mixture thereof, (B) 50 to 75% by weight of a C.sub.4 to C.sub.8 alkyl acrylate or a mixture thereof, and (C) 20 to 49% by weight of methyl methacrylate, styrene, .alpha.-methyl styrene or a mixture thereof. The fabric has sufficient wet tensile strength for use as a diaper coverstock.

Abstract: A method of forming an air laid web of hydrogen bonded wood pulp fibers is disclosed. More specifically, a paper producing method is disclosed wherein microencapsulated hydrogen bond promoting material is thoroughly premixed with wood pulp fibers. The mixture is then air laid on a moving screen to form a three dimensional continuum. The microcapsules may then be ruptured by heat and/or pressure to release the hydrogen bond promoting material evenly throughout the continuum. The continuum may then be heated or pressed to further consolidate the web.

Abstract: The Locator Beacon (LB) is an 18 inch diameter hemispherical unit designed to be air dropped via parachute from a search aircraft near an aircraft crash site. The LB is self uprighting when it lands on the ground and its antenna is always oriented for maximum efficiency. When activated, the LB sends out a radio frequency signal on 121.6 Mhz and 243.2 Mhz, this signal can be tracked by aircraft or by ground parties equipped with directional locating equipment. The LB also contains a strobe light beacon to aid in visual acquisition of the unit. The LB remains in the active (broadcast) mode for approximately 20 minutes before resetting itself to the listening mode. External VHF activation of the LB repeats the LB broadcast and strobe light cycle for another 20 minutes.
