Abstract: 920,769. Valves. ROBERTSHAW-FULTON CONTROLS CO. July 17, 1959 [Oct. 8, 1958], No. 24689/59. Class 135. Manual rotation of shaft 42, 40 in an end recess in plug cock 34 turns a cam 52 independently of the cock through a range limited by a radial abutment on shaft washer 82 engaging either side of a pin 90 in the cock, rotation outside this range then turning the cock through pin 90. The cam acts through pin 200, spring- loaded override lever 102 pivoted at 110 and ambient temperature compensating lever 104 pivoting at 198 on the thermal element 196 responsive to the temperature of a vessel on a gas range to position a hinged valve 134, spring- loaded to open and pivoted at 100, for closing at a set temperature indicated by a dial on shaft 42. On shaft rotation to its highest setting, the plug is fully opened. The shaft is then rotated in the opposite direction to set the hinged valve for a required intermediate setting. The plug cock may be turned by rotating the dial towards its low setting to give a low flame at the burner and the shaft is then rotated in the opposite direction to obtain the required temperature setting. The apparatus is calibrated by a screw 168 whose point 170 moves a frame lever 108 pivoted at 100 and carrying the other levers and the hinged valve. In the " Off" and the high temperature position of the dial, an abutment on cam 52 engages respectively with the side of a easing stop.

Title: Disposable pants and method for making them
Inventor: MATSUSHITA MICHIKO
IPC: A61F13/56
Filed: 1992-07-06
Abstract: In a method of making disposable pants, a front body comprising a sheet 2 having elastic stretchability in at least the transverse direction and a rear body comprising a sheet 3 having substantially no elastic stretchability are bonded to each other at 7 and 8 with a transverse dimension of the front body in its transversely contracted state being smaller than a transverse dimension of the rear body so that laterally opposite waist sides of the wearer may be covered by a part of the rear body. This effectively avoids the inconvenience conventionally occurring such that, with the pants of prior art being put on the user, the front body is displaced downward under force exerted thereon as the user's legs move or under a weight of excretions accumulated in the crotch area of the pants, resulting in loosened leg-openings through which leak or excretion may occur. The front and roar bodies may be liquid impermeable sheets, and the pants may also include liquid permeable, non-stretch inner sheets and an absorbent core sandwiched between the permeable and impermeable sheets. <IMAGE>

Filed: 1993-11-10
Abstract: A downhole, inline well safety shutoff valve (30a) has a spring-loaded flapper shutoff valve element opened by downward movement of an operator tube (40a) slidable within the tubing string bore. The operator tube is vertically driven by a rod structure in an offset passageway (80a) in the valve housing and operated by fluid control pressure transmitted from the surface. To preclude undesired communication in the passageway between pressurized production and control fluids, the rod structure is slidable within a seal structure including a cylindrical sleeve (226a) coaxially received in the passageway, and a sealing ring (224a) between the top of the sleeve and an annular ledge in the passageway. The sealing ring creates a dynamic seal around the rod side surface and a static seal with the interior passageway surface. When the rod structure is driven upwardly, a seating ball (250) carried on its top end contacts an annular sealing surface (252) to form a static seal above the sealing ring. When the rod structure is driven downwardly, an undercut portion (243a) forms a static seal with a lower end portion (238a) of the sleeve. <IMAGE>
