Title: Tampons
IPC: A61F13/24
Filed: 1972-08-18
Abstract: 1400769 Tampons PROCTER & GAMBLE CO 18 Aug 1972 [18 Aug 1971 (2)] 38702/72 Headings A5R A catanerial tampon comprises a flexible, resilient, elastic absorbent body which is capable of expanding from a compacted configuration without relying on the action of fluids to release any compression set which may have occured in the compacted state, the body having an internal discontinuity and having a maximum preipheral length, in a plane transverse to that axis of the absorbent body which in use, is parallel to the longitudinal axis of the vagina, of at least 5.5 inches when undeformed, and the absorbent body being such that two equal and opposite forces each of from 0.05 to 1.0 pounds acting on the tampon and directed radially to said axis thereof, and applied in said transverse plane containing the maximum peripheral length, can deform the tampon to a state in which the maximum transverse dimension of the tampon in said plane is at least 15% greater than the magnitude of this dimention when the tampon is undeformed. The internal discontinuity may be provided by one or more slits or by a spherical cylindrical or rectangular cavity. The absorbent body 10 is preferably conical, said axis passing through the centre of the cone base and through the cone apex to which a withdrawal string 12 is attached, an internal conical cavity extending from the base coaxially with the outer surface 11 of the body 10. The body 10 may be made of an open celled, mensesphilic polyurethane foam, the base diameter of the cone being 1.75 to 3.0 inches and its height 1.75 to 3.00 inches, and the cavity base diameter being about 61 percent of the base diameter of the body 10. The foam is preferably such that said maximum periphery is reduced by no more than 10 percent when the body is collapsed, the body having a modulus of compressibility in the dry state of 0.2 to 0.6 lbs per square inch and the foam having a critical surface tension of at least 60 dynes per cm, a cell count of 20 to 100 cells per linear inch, and being porous to the extent that the air flow in a direction parallel to the direction of foam rise during formation, which direction is preferably transverse to said axis, through a 0.4 inch thick dry foam is 30 to 200 cu ft per min, with a pressure differential of 0.5 inch of water across the foam. The absorbent body is also wetswellable by at least 25 percent of its dry volume, and is compressible by an encircling 0.5 inch wide band subjected to a tensile force of 600 grams so that the tampon has a maximum transverse dimension within the band of less than one inch at each position of the band with respect to the tampon axis. The body 10 may be made from one or more unstressed blanks of the foam, each blank having lateral edges, by bending the blanks around said axis to form a circular cross sectional tampon with said lateral edges in a plane with said axis thereby imparting a tensile stress to the exterior surface and a compression stress to the internal surface, adjacent ones of said lateral edges then being attached to each other and the formed body 10 then being everted.

IPC: F23N1/08
Filed: 1959-11-20
Abstract: 953,654. Valves. MAIN WATER HEATERS Ltd. Nov. 11, 1960 [Nov. 20, 1959], No. 39544/59. Heading F2V. In an automatic control valve for a waterheater valve 17 opens to pass more water to the heater connected at 19 when the water temperature rises as detected by a thermal bellows and capsule 25, and vice versa. Initially, a by-pass manual valve 32 is opened to operate a gas burner valve and as the water temperature rises, so valve 17 is opened to maintain a constant temperature. Valve 17 and its diaphragm 14 act as an inlet water pressure governor, the space 12 above the diaphragm opening to atmosphere on downstream of a restriction 20. Valve 32 may be dispensed with, in which case the gas and water valves are interconnected, while in another embodiment, as valve 17 opens above a certain limit, it contacts the gas valve to close it. In this ease, when the water flow ceases, the spring-loaded diaphragm moves to close the gas valve. Both water and gas valves may be temperature controlled separately or the capillary pipe 27 may lead to two bellows, one for each valve. The bellows and diaphragm loading springs 26, 24 may be adjustable.
