Abstract: 1,243,821. Helicopter rotor bearings. MESSERSCHMITT-BOLKOW-BLOHM G.m.b.H. 4 Oct., 1968 [4 Oct., 1967], No. 47216/68. Heading B7W. [Also in Division F2] A helicopter rotor comprises a hub 1 connected to blade roots such as 8 by laminated elastomer/metal bearings so that the forces acting on each bearing are substantially normal to the laminations of that bearing. Blade root 8 is connected to the arms 6 of stirrup 5 by pin 7, and stirrup 5 is linked through a stirrup 4 and separated therefrom by laminated bearing 9. The arms of stirrup 4 are connected to mountings 2 on hub 1 by pins 3. Stirrup 5 has an extension 12 housed in laminated bearing 13, while stirrup 4 has an extension 10 housed in laminated bearing 11; a threaded part 14 of extension 10 has a nut 16 which, with laminated bearing 15, may be used to pull extension 10, and hence to stress bearing 9. In operation, flexible blades are used to provide flapping and blade lead-lag; bearings 11, 13 have laminations parallel to the blade axis and absorb the forces transverse to the blade, while bearing 9 has transverse laminations and absorbs radial forces. The bearings are easily deformable in shear to allow variations of blade angle. Pre-stressing bearing 9 with nut 16 prevents looseness in the bearing when the rotor is stationary. An embodiment using two conical bearings is described, Fig. 3 (not shown).

Abstract: 1,062,637. Knitting; tufting-m a c h in e s . NAHWIRKMASCHINENBAU MALIMO VEB. Dec. 5, 1963, No. 48104/63. Headings D1C, DIG and D1K. A pile fabric is produced on a warp knitting- machine by knitting independent chains of stitches 7 through a base fabric 1 and causing pile loops 2 on the opposite face of the fabric to be extended by looping the yarns from the guides around loop forming members 6 as they feed the yarns to the needles 3. The loops are extended by racking the members 6 sideways after the needles have been withdrawn and this sideways movement occurs in opposite directions in succesive course. The extent of the pile loops can be varied by varying the racking movement of the members 6 or by not moving them at all. Patterning effects can be achieved by racking some members to a greater extent than others so as to produce loops of different lengths. Points can be used for the members 6 which when retained stationery fail to create any pile loops in the fabric.

Patent GB-489529-A (GB)
IPC: G03C7/14
Abstract: 489,529. Colour photography. KODAK, Ltd. Sept. 14, 1937, No. 24949. Convention date, Oct. 28, 1936. [Class 98 (ii)] A broken-tone multicolour photograph is obtained by producing continuous-tone colour records constituted by light-sensitive silver salt in a photographic element having differentially colour sensitized emulsions on one side of a support, and by converting each continuoustone record into a broken-tone record by exposing through lenticulations on the support to fogging light passed through a banded filter each band of which permits the passage of light which can act on one only or all but one of the emulsions. A lenticular support may be provided on its plane surface with superimposed emulsion layers, or a layer of mixed particles, or a combination of these. The lenticulation may be provided after exposure to a coloured image, or an originally lenticulated support 10, may be used and the lenticulations 11 temporarily obliterated prior to exposure by a removable layer 12 of broken-down gelatine or glue. A substratum coating comprising gelatine, acetone and water may first be applied. The emulsion layers B, G and R are sensitized to blue, green, and red respectively, and the layer B contains a yellow filter-dye. Separate filter layers between the emulsions may be used. After exposure, the layer 12 is removed and the film exposed through the lenticulations to light passing through a three-band filter of colours blue-green, magenta and yellow. This leaves three unfogged areas in three different layers in registration with each lenticulation, and after development by the reversal process these fogged areas are bleached and a positive lenticular record is obtained. The fogging may be effected by feeding the film continuously through a lenticular printer. The film may be exposed originally from the emulsion side, and in this case the lenticulations are not temporarily obliterated. One of the emulsions may then be sensitized for infra-red, and an infra-red component may be employed in the fogging light. The film may also be exposed through the lenticulations without a multicolour filter and using a suitable objective. In the production of lenticular negatives, the element is, after exposure, developed, fixed and reconverted to silver halide. The element is subjected to fogging exposure, using lights each affecting one emulsion only, and is developed and fixed. Colour sensitizing and filter dyes resisting developing, fixing and bleaching are employed and the latter are finally removed with a powerful reducing agent.

Abstract: 1,161,338. Thermosetting resin foam. PLASTUGIL. 9 Nov., 1966 [12 Nov., 1965; 21 July, 1966], No. 50285/66. Headings C3C and C3R. A thermosetting resin foam comprising a condensation product of formaldehyde with a phenol, an amino derivative or a mixture of both is prepared by adding to the resin in aqueous or organic solution in a volatile solvent a foaming agent and an acid hardening catalyst which behaves as a strong acid and is volatile at the temperature of the subsequent drying, drying the hardened foam thus obtained at from 100 to 140 C. for 1 to 3 hours so as to eliminate the water or volatile solvent and the major part of the acid contained in the foam, and thereafter neutralizing the residual acid by means of a gaseous alkaline agent, such as ammonia, if necessary under increased pressure or a vacuum. The amino derivative is a compound containing one or more -NH 2  groups, such as urea or melamine, which is conventionally used in the preparation of the so-called "amino-resins" or "amino-plastics" by condensation with formaldehyde. Specified thermosetting resins are resol-type phenol resins in solution; resol-type phenol resins which are modified or mixed, in which a part of the phenol is replaced during condensation with the formol by urea and/or melamine; modified or mixed resol-type phenol resins obtained by mixing at the foaming stage a phenol resin with other thermosetting resins such as formol-urea formol-melamine or formolurea-melamine resins, pure or modified aminoplastic resins resulting from condensation of formol with urea, melamine or a mixture of both, optionally containing thermoplastic products such as polystyrene in dispersion; and phenol-aminoplastic-styrene mixed resins obtained by simultaneous condensation of a phenol and an amino-derivative and polymerization of styrene (the monomers) or in the form of a mixture of the respective resins which are each condensed so as to result in good compatibility of the final product. Light hydrocarbons can be used as the foaming agent and the preferred catalyst is hydrochloric acid. The neutralized foam can be covered with an insulating and protective varnish so as to insulate it from contact with the surroundings.
