Filed: 1958-02-07
Abstract: 1,062,530. Pulse radar. SPERRY GYROSCOPE CO. Ltd. Feb. 9, 1959 [Feb. 7, 1958], No. 4092/58. Heading H4D. In a control system for an aircraft which is to be flown at a constant low altitude over land, the aircraft height and the range of obstacles in the line of flight are detected by a pulse radar equipment mounted in the aircraft. The aircraft pitch control system is operated by the radar receiver to direct the craft upwards over the obstacles. A threshold range is established arbitrarily, and obstacles having a range beyond this give no signal while for those obstacles within the threshold range, signals are developed proportional to the distance within that range. The antenna scans perpendicularly to the craft roll axis forwardly and vertically downwards. At each elevation angle of scan the echo pulse is compared with the corresponding threshold range signal to provide the obstacle warning signal. The largest of these is fed to the control. Deviation in height from a datum, as measured by the radar in the vertical scan position, causes application of a correcting signal to the pitch control system. An integrating circuit is included in the control channel to produce an increasing pitch angle causing the aircraft path to curve upwards. The path curvature is limited to prevent overstressing of the aircraft frame and the control signal component due to the obstacle signal is arranged to exceed that due to the altitude control.

Title: A process for silvering glass or other similar transparent or translucent materials
IPC: C03C17/40
Filed: 1934-02-08
Abstract: 432,587. Silvering. DURO-RAY, Ltd., 97, Cheapside, and BARNES, A. M., 7, Princes Gardens, Hanger Hill, Acton, both in London. Feb. 8, 1934, No. 4233. [Class 93] [See also Group XXXVI] In silvering glass or similar transparent or translucent materials, films of colloidal silver only are formed to predetermined linear thickness on their surfaces to facilitate the electrodeposition of metals for protective purposes. A silvering-solution is prepared by adding sufficient ammonium hydroxide to an aqueous solution of silver nitrate to convert the silver nitrate to silver oxide and to redissolve the precipitated silver oxide in an excess of ammonium hydroxide, mixing the solution thus formed with an aqueous solution of sodium hydroxide, adding sufficient ammonium hydroxide to redissolve any excess of silver oxide appearing as precipitate, and diluting the mixture with water to a point where the original silver nitrate content is 5 grams per litre and the original sodium hydroxide content is 4À68 grams per litre, and a reducing-solution is prepared by dissolving a mixture of cane sugar and tartaric acid in water. Equal volumes of the silvering and reducing solutions are placed in vessels which are mounted above the work to provide a gravity feed or which have a compressed-air feed, and the solutions issue under the control of valves through two nozzles arranged at an angle of say 45 so as to mix to form a single jet, the time of action being set to provide the required thickness of deposit. The sheet of glass to be silvered may be attached to a vacuum cup, and a spindle carrying a ball engaging socket on the cup supports the glass on a circular table for rotary movement in a horizontal plane, or the spindle can be lifted and rotated in an inclined position to cause the silvering solution to flow over the surface of the glass. Alternatively, the glass may be mounted on a table which may be inclined to secure the glass at an angle to the horizontal. The silver deposit is backed by an electrolytic deposit of lead, the electrolyte being as nearly neutral as possible so that the adhesion of the silver to the glass is not adversely affected, e.g. the electrolyte may be an aqueous solution of lead perchlorate in which the lead content is 37À5 grams per litre and the free perchloric acid is 0À05 per cent. Clove oil or peptone may be added to reduce the grain size of the deposited lead to a minimum.

The electrolyte in a sealed accumulator is absorbed in the electrodes and separators, and oxygen liberated at the positive electrode is absorbed by the rear surfaces of the negative electrodes that are not covered by the separators. Fig. 1 shows an accumulator with one positive electrode 2 and two negatives 4 separated by diaphragms 6. A small quantity of free electrolyte 7 may occupy the lower end of the container into which the separators extend. The rear faces of the negative electrodes are separated from the container walls by distance pieces 8 so that oxygen from the positive electrode can penetrate to the rear faces of the negative electrodes and become absorbed. Fig. 2 shows in plan an accumulator having two positive electrodes 2 each of which is associated with two negatives 4 which are separated from the container and from one another by distance pieces 8 to provide spaces 9 into which oxygen can penetrate and become absorbed in the parts of the negative electrodes not covered by the separators. At the moment of closing the cell the positive electrode is in a condition to generate oxygen while negative electrode generates no hydrogen.
