Abstract: 1503646 Cathode-ray tube displays SMITHS INDUSTRIES Ltd 25 March 1975 [29 March 1974] 14073/74 Heading H4T In an aircraft mounted cathode-ray tube "headup" display, a camera 14, Figs. 1 and 2 (which may be a television camera, an infra-red camera producing video signals or, a forward-looking radar) mounted in or on the aircraft supplies video signals representative, substantially, of the view seen by the pilot along the line-or-sight 2, to a video mixer 15 in which they are combined with the (analogue) signal output of waveform generator (11), which produces the display of a horizon symbol 7, a flight vector symbol 8 (Fig. 3) and a weapon-aiming symbol 9 on the screen of tube 5, the combined signals from mixer 15 being recorded on video tape by means 17. The tape, which may be removed for subsequent analysis, e.g. at the end of a training mission, may also be "played-back" and displayed on a monitor 18 (Fig. 4) which can be readily viewed by an instructor during flight. As shown in Figs. 1 and 4 the instructor (upper rear seat) is provided with a semi-reflector 1<SP>1</SP> and display unit DU' similar to the elements 1 and DU at the pilot's position and additionally by means of switches 20 and 21 and instructor may, selectively, display on his unit DU', the signals from waveform generator either alone or in combination with the video signals from either the mixer 15 or from the camera 14. The signals from mixer 15 may also be transmitted via transmitter 19 for reception at a ground station.

Abstract: <PICT:0823022/IV(c)/1> <PICT:0823022/IV(c)/2> A vessel, e.g. a dyeing vessel, has a pressure-sealing device including two rollers 3, 4 mounted in an opening 1 such that their axes are substantially parallel, the rollers being arranged to contact any length of material passing therebetween, there being a means, e.g. compression springs 11 which urges one roller towards the other in order to prevent substantial leakage, between the rollers of pressure medium within the vessel, there being plates 13 disposed between the end-faces of the rollers and the adjacent sides of said opening, said plates serving to prevent substantial leakage of pressure medium, there also being two other plates 14 serving to prevent leakage of pressure medium between the rollers and the remaining sides of said opening, each plate being attached to a respective one of said remaining sides and one of its faces bearing upon the curved surface of the adjacent roller along its entire length.  Roller 4 can be moved up to and away from roller 3 by rotation of hand wheel 8 acting on block 5 by way of spindle 9, plate 10 and springs 11.  Referring to Fig. 2, the rollers may comprise a steel jacket 3b surrounded by rubber coating 3c.  Edges 3d of coating 3c preferably project beyond the end faces of the roller so as to co-operate with annular plates 13.  There is preferably provided in the external gusset defined by the rollers a liquid bath 16 (Fig. 1), for the continuous chemical pre-treatment of material entering the vessel.  Rollers 3 and 4 may be caused to move towards each other.  The vessel may have in addition a pressure sealing exit device.  Plates 14 may be of resilient steel or rubber and may be pivotably attached to the vessel and urged by springs against the rollers.

Title: Improvements in or relating to phenol-formaldehyde condensation products and to the production thereof
IPC: C08G8/28
Filed: 1919-06-10
Abstract: The condensation of phenols with formaldehyde or its equivalents is effected in the presence of a very small proportion of nitrocellulose or cellulose acetate; the maximum amount of cellulose ester used is about 0.8 per cent reckoned on the phenol. The use of nitrocellulose renders the product odourless, while cellulose acetate also confers increased toughness.  In an example, cresylic acid, formaldehyde, caustic soda, and cellulose acetate (0.000025 per cent) are employed; the liquid product is boiled down, baked at atmospheric pressure, and may be further treated in an autoclave.

Filed: 1947-06-05
Abstract: 630,038. Opening oysters &c. FRADUA, S. LAYDA-. June 5, 1947, No. 14918. [Class 28(ii)] To open oysters &c. and retain the savoury fluid, in the concave half-shell the oyster is held by a descending clamp 1 in a housing 20 of a table while a cutter 6 then descends and bores a hole through the shell at the point of adhesion of the inside muscle holding the shell halves together. The upper shell can then be removed. Alternatively the muscle may be cut by a rotated spring blade 30 which also descends along a curved groove in the shell cutter 6 to project radially. A hand-operated counter-weighted lever 22 serves to lower the blade 30 into the hole after it is bored. A hand lever moves the clamp 1 down to a gripping position through a rack and pinion while a handwheel 7 is used to lower or raise the boring cutter 6. The cut shell half 19 may be lifted out along with the cutter as it is raised. Motor power is supplied through a bevel gear 13. In a simpler form without a rotated muscle cutting knife, Fig. 1 (not shown), a ring of shell is bored out and then lifted out by hand along with the adhering inside muscle. A spring ejector forces the cut ring of shell out of the peripheral boring tool. Fig. 9 shows the device mounted over a turntable 21 having a number of recesses each for an oyster.

Title: Improvements relating to aircraft with folding wings
IPC: B64C3/56
Filed: 1938-05-19
Abstract: 577,783. Aircraft folding-wings. GENERAL AIRCRAFT, Ltd., and LEATHER, G. B. May 19, 1938, No. 14965. [Class 4] An aircraft wing which for folding is raised or lowered and subsequently turned, is connected to a part which carries it by at least two fittings, one of which provides a hinge axis for folding whilst at least one other fitting serves at least to assist in locating the parts in the spread condition of the wing, but in raising or lowering the wing leaves the wing free for folding. In one form, a stub-wing 10 carries at its front spar a bracket 17 having parts 18, 19 which engage an axially displaceable pin 14. A sleeve 15 is rotatable on the pin 14 and is connected to the front-spar of a folding-wing by a rib 16. The part 18 is slotted to receive the rib 16. The pin is provided with a sleeve 21, a nut 22 at the lower end of which engages with a screw-threaded shaft 23 mounted'against axial movement in a bracket 25, carrying a sprocket-wheel 26 and provided with a square end to receive an operating handle 28. The rear spar of the stub wing carries a bracket 33 having parts 34, 35 which engage a trapezoidal pin 29B displaceable by screw 38 and nut 39 on rotation of a sprocket 42. A pin 29s is connected by a rib 32 to the rear spar of the folding wing and is adapted to overlap and engage by means of a pin 31 the pin 29B. Thus, on rotation of the sprockets, the folding portion of the wing is raised clear of the stub wing and may then be folded by pivoting about the pin 14. A chain 43 connects the sprockets. In a modification, the nuts are fixed axially, are rotatable by worm or skew gearing and engage displaceable screws which are held against rotation by a flat surface which engages a corresponding surface on the bracket on the stub wing. The mechanism may be disposed within the depth of the wing or may be enclosed in fairings.
