Filed: 1970-09-01
Abstract: 1285508 Pulse radar NORTH AMERICAN ROCKWELL CORP 1 Sept 1970 [26 Nov 1969] 41854/70 Heading H4D In an airborne ground mapping radar system the movement of the aircraft during an azimuthal radar scan leads to "smearing" of the display on an extended target, Figs. 1,2 (neither shown); to avoid this, the invention integrates the velocity vector of the aircraft during the interval corresponding to an azimuthal scan to bias the display 17 and the integration is reset at the end of that interval. The embodiment includes slant range compensation 19. Checkpointing means utilizing stored co-ordinates of preselected targets may be incorporated to correct an inertial navigation system, Fig. 5 (not shown). If the scanning is by a phased array, roll correction is incorporated, Figs. 8, 9 and 10 (none shown).

Abstract: 1412433 Winding webs G LOOSER 12 Sept 1972 [13 Sept 1971] 42315/72 Heading B8R [Also in Division B4] A cutter mechanism, e.g. for cutting a web in a continuous web winding operation, comprises a cutting knife 95 rotatably mounted on a carriage 88 movable by a drive means, e.g. a reversing motor acting on a chain 156 attached to the carriage, along guide rails defined in a bar 90 and arranged with its cutting plane inclined to the direction of movement of the carriage so as to cut the web diagonally with respect to the lengthwise axis of the web; a drive wheel 128, which engages one of the rails, is rotated during carriage movement and transfers such rotation, e.g. via bevel gears 160, 164 and shaft 166, to the cutting knife 95. As described, the mechanism is incorporated in an apparatus for continuously winding webs in which a tubular thermoplastic web 12 is slit longitudinally and separated at rollers 26, 28 and is wound on to a reel R in contact with a continuously rotating winder drum 36, the reel core being held in the bifurcated ends of a pair of pivotable transfer arms 102. When a desired length of web has been measured by a counter 48, bifurcated arms 64, supporting the cutter mechanism C and rotatably mounted on the winder drum shaft 38, are rotated anti-clockwise through 120 degrees to the Fig. 1 position and an adhesively coated empty core 66 is released from a magazine 68 to the arms 64. Switches 84 on the arms sense the core and operate a cutting stroke, in which the carriage 88 supporting the rotatable knife disc 95 moves across the web. On carriage return, the transfer arms 102 are hydraulically pivoted to deposit the full reel R in the rotatable arms 104 of a store S whilst the cut, leading web end begins winding on to the empty core. The transfer arms then return and the arms 64 are rotated further anti-clockwise so that as the reel grows, the new core is pushed out of the arms 64 and drops into the transfer arms.

In a photographic metal salt transfer process, a photo-conductive sheet material containing a water-soluble metal salt is imagewise exposed to form a latent or visible metal or metal-containing image and, if desired after a development step, is then contacted in the presence of an aqueous solvent with an image-receiving sheet so that a positive metal salt image is transferred in the unexposed areas. The receiving sheet may be a photo-conductive material and may be uniformly exposed before or after transfer of the metal salt image, or it may be a sheet containing development nuclei. The metal salt image obtained on the receiving sheet may be made visible by development and may then be fixed. Photo-conductors specified are TiO 2  and ZnO, metal salts mentioned are those of Ag, Au, Hg, Cu, Pt, Mn, Pb, Ni, Sn or Cr and in particular silver nitrate, acetate, sulphate and thiosulphate.

In a process of forming a sintered alloy foil e.g. 0À001''-0À008'' thick a supporting carrier such as stainless steel strip is coated with a slurry of the powder constituents of the alloy and a binder which is dried and squeezed to bond the particles, the coating is removed from the carrier, presintered, squeezed as by rolling and finally sintered. The following alloys are specified as examples: 71% Ni - 10% Si - 19% Cr; 92% Ni - 4À5%Si-3À5%B; 80/90% Fe - 10/20% Al; 90% Cu - 10% Ti; 70/75% Ni - 25/30% Ti. The binder used is a long chain high molecular weight organic compound such as methyl cellulose, cellulose ether, polyethylene oxide, polyvinyl pyrallidone with water as a carrier. The powder constituents of the alloy should have a particle size less than 100h, mainly 50 h. and the slurry formed should contain 50 - 75% solids with a viscosity of 1000-4000 c.p.s. As shown in Figure 1 the slurry 9 is coated on a stainless steel strip 1 by rollers 19, 21 to form a wet coating 0À010" thick. The coating is dried by resistance heating of the strip 1 via 33, 8 and 10 and the dried coating is rolled by rollers 39, 41 to a 10-50% reduction. The coatings 34, 36 formed on both faces of the strip 1 are removed and presintered in argon or hydrogen in furnaces 43 and 45 respectively, the temperature being insufficient for homogenization of the alloy. The presintered strips are rolled at 47/49, 51/53 respectively to a 5-40% reduction and finally sintered at 55 and 57 respectively. The process is of particular value for brittle alloys since the rolling is carried out on the presintered strip i.e. before alloying has occurred to form the brittle alloy.
