Patent EP-0393269-A1 (EP)
Inventor: GLASGOW JOHN A
IPC: G01S13/28
Filed: 1989-04-19
Abstract: Synthetic aperture sonar apparatus for mapping a target area divides the across track range into two or more divisions, and has a receiver (4,11) for each range division. A number of distinguishable pulse signal forms, equal in number to the square of the number of range divisions, are transmitted in a predetermined sequence, enabling each receiver (4,11) to identify signals received only from its appropriate range division, thus improving across-track range resolution. 
     In another embodiment of the invention, a continuous noise-like waveform is transmitted and signal returns compared with reference waveforms derived from the transmitted signal to obtain the range of a target.

Abstract: Fabrics are made electrically conductive by contacting the fiber under agitation conditions with an aqueous solution of a pyrrole compound, an oxidizing agent and a doping agent or counter ion and then depositing onto the surface of individual fibers of the fabric a prepolymer of the pyrrole compound so as to uniformly and coherently cover the fibers with a conductive film of the polymerized pyrrole compound and wherein, furthermore, the oxidizing agent is a ferric salt and the aqueous solution further contains a weak complexing agent for ferric ions to effectively control the reaction rate such that the prepolymer is uniformly and coherently adsorbed onto the surface of the textile material, thereby providing improved films of electrically conductive polymerized compound on the textile material.

Abstract: To prepare a potassium ferrate, 100 parts of ferrous sulphate heptahydrate and 68 parts of calcium hypochlorite with a chlorimeter value of 210 degrees are ground intimately to obtain a powder which passes through a 500- mu m mesh. This powder is formed into a layer onto which are scattered 100 parts of potassium hydroxide pellets containing 15% by weight of water. The whole is vibrated for 10 to 60 minutes, depending on atmospheric moisture content, while care is taken that the temperature does not exceed 40<o>C. The unreacted powder is removed by screening through a 1-mm mesh and the pellets are stoved at 120<o>C for 12 hours. The pellets are washed with methyl alcohol to remove most of the remaining potassium hydroxide and potassium chloride and carbonate as well as calcium chloride. The ferrate obtained, purple in colour, is stable in a closed vessel.

Abstract: The invention provides a deeply-embossed vinyl wallpaper made from a vinyl laminate face sheet and a backing sheet, with or without a printed design on the face sheet, and a method of manufacturing the same. 
     A vinyl laminate sheet (1) employed as the face sheet, and the backing sheet (2), are unwound continuously from respective drums and the adhesive is applied to the backing sheet (2) by an applicator (3). At a combining nip (4), the two sheets are joined together and bonded by the adhesive. The smooth laminate is fed through print stations (5) where any desired printed design can be added to the exposed surface of the vinyl coating. Then, in an embossing unit (6), the laminate is given a deep embossing by being forced through engraved rollers. The manufacture is completed by passing the embossed laminate through an oven (7), so as to dry out the laminate and to cure the adhesive thereby rendering it insensitive to moisture. The finished wallpaper is wound on a rewind drum (8).
