Patent GB-637409-A (GB)
Abstract: 637,409. Filters. WRIGHT, A. Oct. 27, 1947, No. 28621. Convention date, Oct. 29,1946. [Class 46] A continuous rotary drum filter including a series of cord convolutions forming a filter web with the cords overlapping so that alternate cords are at a different distance from the drum than are the intervening cords, has longitudinallyextending sealing elements formed of self deformable solid material that extends into contact with the most distant cords, and dove-tailed holders for the sealing elements preventing circumferential displacement of the sealing elements, the radial height of the dove-tailed holders being less than the radial extent of the sealing elements by at least the radial spacing of successive cords. As shown in Fig. 2, a self-deforming sealing member 34, of rubber, neoprene, or equivalent synthetic material, is housed between two supporting strips 33, 331, forming a dovetail slot, which are secured to a plate 30. A gasket 32 is inserted between the plate 30 and the drum surface 14. The edges of the strips 33, 331 may be scalloped, as shown in Fig. 4, where the strips are secured directly to the drum surface 14. The sealing member 34 may be rectangular in cross-section, or it may have tapered sides to conform with the inclined supporting strips. In any case its width should be slightly greater than the spacing between the strips so that it is kept in place in all positions of the drum. The lower of the two sets of cord convolutions 13, forming the filter web, is in contact with the drum surface in the regions between the sealing members 34. U.S.A. Specifications 2,247,460 is referred to.
Patent GB-674497-A (GB)
Abstract: 674,497. Stoves. WEISS, H. (trading as MELLER. K., [Firm of]). July 11. 1950 [Aug. 2, 1949], No. 17394/50. Class 126 The supply of combustion air to a stove is regulated by a device controlled by a heat-gauge exposed to the cooling action of a separate auxiliary air stream drawn in by the chimney draught, and means are provided to eliminate the effect of fluctuations in the heat of the stove on the heatgauge., The entry of combustion air V to a stove is controlled by a flap 3 operated by an arm 4 connected to a bimetallic strip 5, mounted in a tubular, metallic member 8 which is swingably mounted in the end of a passage 10 communicating with the chimney. An auxiliary air stream H, drawn in by the chimney draught, cools the bimetallic strip 5. The strip 5 and connecting arm 4 are so adjusted by set screws 16, 17 respectively that the supply of combustion air remains constant despite changes in chimney draught. Changes in the temperature of the stove are counteracted by means of bimetallic strip 11 mounted in a heat-conducting casing 14 on the front of the stove, and arranged to move the tubular member 8 away from the stove when the temperature increases. An insulating screen 15 may be provided on the part of the member 8 facing the wall of the stove. In a modification, Fig. 3 (not shown), the effects of fluctuations in the temperature of the stove are eliminated by providing a throttle valve in the auxiliary air stream, controlled by a correction heat-gauge. The throttle valve may be in the form of a tongue-shaped extension of a bimetallic strip, projecting into the auxiliary air stream.

Title: Sliding face seal
IPC: F16J15/36
Filed: 1980-06-19
Abstract: A sliding face seal, for use in a motor vehicle engine water pump, has a cylindrical housing 10 with an open end and an annular bottom 12 at the other end. A rigid graphite ring 14 is located within the open end of the housing and is movable axially but not rotatably therein.
