Title: Improvements in or relating to colloidal solutions
IPC: G03C11/08
Filed: 1944-03-13
Abstract: A colloidal solution for application to articles such as lenses, photographic prints, &c. to provide a non-reflecting surface comprises an evaporable organic liquid having suspended therein 3 per cent or less of microgranular transparent particles. A suitable liquid is obtained by diluting "Silica Aquasol" (an aqueous colloidal silica solution) with an organic solvent such as that known by the Registered Trade Mark "Cellosolve."  Other colloidal solids which may be used are lithium, magnesium, strontium, calcium and barium fluorides, cryolite and titanium dioxide.  Surface tension-reducing agents such as sulphonated higher alcohols may be included in the composition, and a fortifying agent, e.g. tetraethylorthosilicate, may be added to strengthen the coating.  The use of the solutions is described in Specification 594,524, [Group XX].

Title: Improved devices for the automatic control of camber flaps and the like for airplanes
IPC: B64C13/00
Filed: 1936-01-31
Abstract: 456,863. Controlling aircraft. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M., 1, Route des Alpes, Fribourg, Switzerland. Jan. 31, 1936, No. 3022. Convention date, April 5, 1935. [Class 4] A camber-changing flap or like element of a high-lift aeroplane wing which is so mounted that the action of the relative wind tends to restore it to a neutral position is operated by means including a pneumatic or hydro-pneumatic accumulator which serves to store the energy necessary for causing downward movement of the flap, the energy being stored during the previous retracting movement of the flap. As shown, a flap 1 is controlled by rod 3 of a piston 4 movable in a hydraulic cylinder 5 which communicates at one end by a pipe 6 with a hydro-pneumatic accumulator 7 and at the other end by a pipe 11 with a pump 12 adapted to draw liquid from a tank 13. A valve 15 when open places the pipe 11 directly in communication with tank 13. In its operative position flap 1 is held by the pressure of the air in accumulator 7, which pressure is so regulated that the flap returns to neutral position at a predetermined air speed. In order positively to retract the flap, valve 15 is closed and pump 12 set in motion thereby forcing piston 4 in the direction further to compress the air trapped in the accumulator cylinder. The flap is moved downwardly on opening of valve 15. Specification 454,490 is referred to.

Abstract: 751,775. Cofferdams. CEMENTATION CO., Ltd. March 18, 1955 [Feb. 4, 1954], No. 3324/54. Class 68(2) In a method of producing a sub-aqueous structure, such as a cofferdam, which is subject to hydrostatic uplift steel piling 3 is driven into the sea bottom consisting mainly of clay 1 to enclose a rectangular area, and extends above the surface 2 of the water, there being below the clay 1, a layer of water bearing gravel 4 subject to the full hydrostatic pressure and a stratum of rock 5. Metal tubes 6 are then driven into the bottom 1, their upper ends remaining above the level of the water 2, each tube having a boring rod extending into the rock 5. A high tensile cable 7 is threaded down each tube and grouted at 8 in the bore hole.. Concrete is then poured into the water enclosed by the piling to form a thick floor 9. After the floor has set the cables are tensioned by jacking them against the upper ends of the tubes 6 and the water within the piling is pumped out. If the concrete floor is subsequently held down by massive plant the cables may be de-tensioned. In an alternative arrangement the concrete floor is laid before the holes down to the rock are drilled.

Abstract: 893,593. Machine-tool details. NEWBRITAIN MACHINE CO. Feb. 1, 1960 [Aug. 12, 1959], No. 3442/60. Class 83 (3). A machine such as a horizontal boring, milling and drilling machine has fluid pressure means for clamping the slidable work-table members and for raising these members, when unclamped, to facilitate movement. The bed A, Fig. 2, of the machine is provided with main longitudinal ways 14, 15, and auxiliary side supports 10, 11. The saddle G is guided along these ways and supports and may be clamped or unclamped under manual or automatic control by a rotatable fluid-motor 62, screwoperated levers 94, 95, and pads 91, 92.
