Title: Mechanical seal assemblies
IPC: F16J15/38
Filed: 1959-03-16
Abstract: 910,601. Stuffing-box substitutes. BORGWARNER CORPORATION. March 16, 1959 [March 31, 1958], No. 9094/59. Class 122 (5). A mechanical seal for a rotary shaft 107 comprises two or more relatively axiallymovable seal rings 109, 110 co-operating with an axially fixed seal ring 124 and forming a chamber 130 to receive fluid leaking between one, 109, of the axially movable rings and the axially fixed ring 124. The relative axial positions of the rings 109 and 110 and thus the sealing pressures at the contact faces 109d and 110d are adjusted by the fluid pressure in the chamber 130 which varies as a function of the leakage rate across the seal. The ring 109 is sealed to the shaft by cup-packing 113 and driven by pins 121 that extend through openings in a bush 117 and engage slots 115a in a skirt 115b, which slots are engaged by lugs 108a on the ring 109. The ring 110 is slidable on the ring 109, sealed thereto by an 0-ring 129 and has lugs 108b engaging slots 108c in the ring 109. A pin 124a projecting into a slot 124b in the seal flange 105 prevents rotation of the ring 124 which is sealed to the flange by packing ring 125. The rings 109 and 110 are urged towards the ring 124 by springs 116 and 132 respectively. In operation, with a constant pressure in the shaft housing 101, when the pressure in chamber 130 changes from normal due to variations in the leakage rate across face 109d or 110d the ring 109 and 110 are automatically moved axially relative to each other by the fluid pressures acting on their radial faces to vary the seeling pressures on the faces 109d and 110d and thereby restore leakage conditions to normal.

Title: Improvements in silicone water-repellent compositions
Filed: 1955-04-01
Abstract: Moisture-unstable polysiloxanes of the unit formula <FORM:0771844/IV(a)/1> wherein n has an average value of from 1/3 to 0.7 are prepared by adding methanol to a solution of methyltrichlorosilane in an inert solvent, and then adding more methanol together with an amount of water equal to from 1.15 to 1.33 mols. per mol. of original silane, the total amount of methanol being at least 1 mol. per mol. of silane.  The preferred solvents are aromatic hydrocarbons, particularly mixtures of alkylated benzenes; others which may be used are chlorinated aliphatic hydrocarbons.  The amount of methanol used in the first stage is generally from 25 to 75 per cent of the total which may be up to 3 mols. per mol. of silane. Reaction proceeds with evolution of hydrogen chloride and lowering of temperature to form two phases, the lower one being separated, washed with additional methanol, neutralized, e.g. with calcium carbonate, and preferably heated to moderate temperatures to remove any residual methanol.  The resins are particularly useful for water-proofing masonry, for which solutions of about 0.5 to 8 per cent concentration in the inert solvent are used.  The solutions dry in air and the resin rapidly condenses to a substantially completely condensed state.  U.S.A. Specification 2,624,749 is referred to.
