Title: Process for increasing the stability of foundations of all types
IPC: E02D27/28
Filed: 1951-03-19
Abstract: 691,147. Soil consolidation. LORENZ, H. March 19, 1951 [April 6, 1950; Dec. 19, 1950; Jan. 23, 1951], No. 6562/51. Drawings to Specification. Class 68(i) [Also in Group X] A method of soil stabilization comprises the insertion under pressure of a thixotropic liquid between the foundation and the soil, the said liquid not penetrating into the pores of the soil because of thixotropic properties but causing compression of the soil. The thixotropic liquid may be a colloid such as bentonite in water. This consolidation may be of such a magnitude that it would correspond to the movement of the ground when a load is put on said foundation. The pressure and quantity of the liquid injected beneath the foundation may be automatically regulated so that the foundation is maintained at a predetermined level irrespective of the movement of the sub-soil. Vertical shuttering or walls permit the introduction of the liquid at various pressures to compensate for eccentric loading, i.e. so as to maintain a uniform loading pressure over the sub-soil. Besides compensation of vertical displacement of a foundation the method is adaptable to compensate horizontal displacements. The method may be adapted for the prevention of undue stressing in foundations as a result of ground subsidence by surrounding the foundation with vertical shuttering and floating it on a layer of liquid under pressure confined within said shuttering the liquid being injected as required through the foundation. Externally of the plates is a trench the bottom of which is lower than the bottom of the liquid below the foundation bottom but above the lower edges of the shuttering the trench being filled with thixotropic liquid which can be renewed when aged. The preconsolidation of the soil in the vicinity of the foundation can be carried out by inserting adjacent the side of the foundation a folded rubber skin closed at the sides and with a metal wedged-shaped sheet embracing one of its lower free ends and pumping thixotropic liquid into the skin to distend it and then passing concrete up into the space occupied by the liquid before the skin is withdrawn. Pipes for supply of the liquid.and of the concrete pass down from above through the skin and out from the foundation. The skin may be replaced by a metal box having an outer perforated side covered with a distendable diaphragm, a liquid being pumped into the box.

Title: Fluid pressure regulating system
IPC: F16K1/12
Filed: 1966-02-16
Abstract: 1,113,141. Valves. VAPOR CORPORATION. 16 Feb., 1966 [5 May, 1965], No. 6755/66. Heading F2V. [Also in Division G3] Valves usable in a control system (see Division G2-- G3) that regulates a pilot's suit pressure in dependence upon cabin pressure or atmospheric pressure include a diaphragm-actuated looseball valve 90 (Fig. 7), a pressure regulator 98 (Fig. 8) and a main valve 20 (Fig. 11), the latter being inserted in the line supplying the cabin and the suit. In the valve of Fig. 7, a ball 222 is biased into engagement with a seat 219 by a spring 224 acting on a cup-shaped ball-support 220, the ball being unseated by a tappet 214 engaged by a spring seat 193 carried by diaphragm 190. The diaphragm is loaded on opposite sides by springs 199, 202 and is responsive to suit pressure at 191 and cabin or atmospheric pressure at 192. The ball controls leakage from a chamber 229 supplied via a restriction. In the regulator of Fig. 8, a ball 126 is urged away from seat 124 by spring 156 acting via diaphragm 132 and plunger 140. Air enters via filter 112 and flows to radial outlet ports 148, 149. When the outlet pressure exceeds a predetermined value, it acts on diaphragm 132 to withdraw plunger 140 thereby allowing spring 130 to seat ball 126. In the valve of Fig. 11, a piston 78 is fast with a spindle 60 and sleeve 74, and a closure member 76 is urged by spring 88 against a stop 75 on sleeve 74. A spring 86 urges the piston rightwardly. Normally the piston and closure member move together under the influence of a control pressure admitted at 52 and upstream pressure at 55. However, if the control pressure is excessive, the upstream pressure unseats the closure member as shown against the action of spring 88.

Title: An improved method and apparatus for melting glass and the like
IPC: C03B5/00
Filed: 1927-03-11
Abstract: 291,883. Frink, R. L. March 11, 1927. Glass furnaces; charging; hearths. -A method of melting glass consists of feeding the batch material on to a surface which is inclined or curved downwards and on which the material is exposed to heat while spread out in a relatively thin layer. The material melts and flows down the surface until it runs off into a collecting chamber or receptacle. The furnace comprises a body portion containing the regenerators, and a hearth or sole 13 having its upper surface inclined. as shown. The sole may be built up, or may be cast in one piece, and may consist of the refractory material described in Specification 306,216, [Class 22, Cements &c.]. The inclined surface may also consist of a layer of refractory material having a low coefficient of expansion, such as sillimanite, and it is formed with upturned sides 14 so as to form a shoot for the batch material. The shoot may be carried by a movable truck 18 running on rails 19 to enable it to be replaced quickly when the blocks are eroded, a spare shoot being kept ready in a heating-furnace. The furnace body comprises end walls 3 and side walls 4, the bottom being formed as a container 6 having an inner wall which is overlapped by the lower end 16 of the sole 13. The upper part of the body contains recuperator chambers 37<1>, 38, 42, which are connected by tubes 29, 37, the lowest chamber, 37<1>, being formed with burner ports 26. The chamber 37<1> also communicates . by a flue 43 with burner ports 27 in the walls of the container 6. The chambers form with the walls of the furnace a flue 28 that conducts burnt gases to the stack 40. A hanging mantle 72, which closes the working-end of the furnace, extends downwards to a floater 73 under which the glass must pass to the working-out point. The working-chamber to the right of the mantle, is heated by the burners 27. In use, air supplied from a pipe 41 passes through the recuperators 42, 38, 37<1> and is mixed in the burners 26 with fuel, either oil or gas, supplied by pipes 32<1>. The combustion of the gases heats the. sole 13 and the burnt gases, passing out through the flue 28, heat the recuperators. The batch is supplied from a bin 7 through a gate 8 to a container which may have its floor 11 watercooled. A reciprocating plunger 10 pushes the batch out of the container through an opening 12. The plunger is a loose fit in the opening 12 in order to prevent jamming. The batch thus fed on to the heated sole moves downwards by gravity and melts during the movement. The molten glass so formed runs off the lower end 16 into the container 6 where it is worked out in any suitable manner.
