Title: Improvements in or relating to soil compaction and stabilization
IPC: C09K17/14
Filed: 1946-11-06
Abstract: Soil is treated so that the optimum content of water and therefore, the strength of roads, embankments &c. is maintained by applying thereto an aqueous emulsion of or containing a petroleum aromatic extract, preferably one which is liquid at normal temperatures, has a pour point of 45-47 DEG  F and a viscosity, measured on Redwood's viscometer at 140 DEG  F. of 650-1250 seconds. One or more substances having water-repellent properties, e.g., a mineral oil, wax, resin, or bitumen, an emulsifying agent, or a protective colloid such as casein may be added to the extract before emulsification. Emulsification is preferably effected at a temperature at which all the ingedients are in a liquid or dissolved state.  The amount of emulsion used is up to 20 per cent of the weight of the soil, the extract content being from 2 to 10 per cent of the weight of the soil.  The water content of the soil is preferably adjusted before addition of the emulsion, this being effected by spraying or mixing in a mechanical mixer. Specification 618,640 is referred to.

Convention date, Dec. 4, 1931. [Class 40 (i).] In a system for repeating the movements of a member such as the movable element of a compass, the member controls the position of a mirror which reflects a beam of light or heat on to light or heat sensitive devices adapted to control a repeating instrument. As shown in Fig. 1, a mirror controlled by the instruments reflects light from a source 1 on to photo-electric cells 2, 3 which are connected in parallel through an amplifier 84 to a repeating instrument 80. The reflected light beam passes through apertured screens 71, 72 the apertures being triangular as shown in Fig. 5, so that the quantity of light admitted to the cells is a function of the movement of the mirror. An opaque screen 89 is arranged between the cells 2, 3 to prevent simultaneous operation of the cells. The apparatus is enclosed within parabolic reflecting surfaces 75, 76 and elliptic reflecting surfaces 87, 88 so that the reflected beam may always be directed on to one or other cell. All the apparatus other than the mirror 14 is mounted on a movable support which may be adjusted manually or by remote control. The cells 2, 3 may operate a differential indicating instrument and may be illuminated by means of convergent lenses instead of the reflectors 75, 76. When lenses are used screens of gradated opacity are interposed between the lenses and the cells. Non-visible rays, such as infra-red, may be used and instead of light, heat may be utilized, the beam being directed on to one or other of a pair of thermo-couples.
