Abstract: 1,174,496. Jet flaps on aerofoils. GIRAVIONS DORAND. 15 June, 1967 [20 June, 1966], No. 27652/67. Headings B7G and B7W. [Also in Division F2] A jet flap mounted on the trailing edge of an aerofoil 1 (e.g. an aircraft wing or a helicopter rotor blade) comprises a deflector flap 3 hinged about an axis 2 parallel and adjacent to an edge of a jet outlet, and a secondary flap 5, located in the path of the jet, and pivoting about the axis 2 to vary the cross-sectional area of the outlet, and to divide it into two apertures 6, 7. The secondary flap 5 may have its upper face curved about the axis 2 so that the aperture 6 remains constant, and always smaller than variable aperture 7. The two flaps 3, 5 may be moved together to vary the direction of the jet, and the flap 5 may be moved independently to vary the jet cross-sectional area. The flap 3 may comprise a second rigid part 9 pivoted at 10, and a flexible surface element 8 forming a flexible continuation of the upper surface of flap 3 and pivoted to the rear end of part 9. In a rotor blade the effective area of the nozzle may be increased along the trailing edge of an advancing blade and reduced on retreating blade, thereby providing additional propulsive thrust. The flaps may be moved in unison in the same direction in the manner of a vectored jet nozzle.

Title: Improvements in and relating to aircraft controls
IPC: B64C13/00
Filed: 1944-01-04
Abstract: 570,030. Controlling aircraft. BLACKBURN AIRCRAFT, Ltd., SMYT1-I, S. J., and HEWITT, J. L. Jan. 4, 1944, No. 113. [Class 4] A control system for aircraft having spring tab balanced control surfaces embodies means which progressively reduces the possible rate of movement of the control surfaces as the speed of the aircraft increases about a predetermined value. In the form shown, the control transmitting apparatus includes a piston rod 3 connected to a piston in a hydraulic cylinder 5, the ends of which are interconnected through pipes 6, 7, incorporating a throttling valve 9. The latter is provided with an elongated port 10 registering with the pipes 6, 7, and is moved against a spring 14 by pressure applied to a piston 11 from a pitot head, through a connection 13. The spring-engaging end of the valve 9 may be connected to a static head by a conduit 15, and a similar connection may be made to the low pressure side of the piston 11. Owing to the elongated form of the valve port 10, the valve 9 is permitted a predetermined axial movement, dependent upon the desired airspeed, before throttling of the fluid flow through the cylinder connecting pipes 6, 7, commences, with a consequent increase in the effort required to move the pilot's controls.

Patent GB-714617-A (GB)
Title: Improvements in the production of aryl ethers
Filed: 1952-01-04
Abstract: Aryl ethers are produced by reacting butine (2)-diols (1.4) with aromatic hydroxy compounds in the presence of mercuric salts of strong acids and hydrogenating the resulting 4-aryloxybutanol(1)-ones(2) by usual catalytic hydrogenation methods. Suitable butine(2)-diols-1.4 are, for example, the unsubstituted diol and its alkyl, cycloalkyl, aryl and aralkyl derivatives such as pentine(2)-diol(1.4), hexine(3)-diol(2.5) and 1-phenyl-, 1-benzyl- or 1-cyclohexylbutine(2)-diol(1.4). Suitable aromatic hydroxy compounds are, for example, phenol, the cresols, xylenols, naphthols and their alkoxy, halogeno, nitro and amino derivatives, their sulphonic and carboxylic acids, hydroquinone, resorcinol, pyrogallol, dihydroxy-diphenyls such as p.p1-dihydroxydiphenyl, dihydroxy-diphenyl ethers, sulphides or sulphones; one or more of the hydroxy groups of the polyhydric hydroxy compounds may be reacted with the butine-diol.  In the case of the unsubstituted butine(2)-diol(1.4) the reaction proceeds as follows: ROH + HOCH2-C­C-CH2OH --> ROCH2-CH2-COCH2OH --> ROCH2-CH2 -CH(OH)-CH2OH ROH representing an aromatic hydroxy compound.  A mercuric salt or a mixture of mercuric oxide with a strong acid such as sulphuric acid, boron fluoride hydrate (Fl3BOH)H or boron fluoride phenolate (F3BOC5H5)H, may be used as catalyst. Preferably a diluent is used. In the examples (a) mercuric sulphate is added to a mixture of butine(2)-diol(1.4) and o-cresol; when the carbonyl number no longer increases the mixture is heated and neutralized with calcium carbonate and filtered; the 4-(o-cresoxy)-butanol-(1)-one(2) is then treated with hydrogen in the presence of Raney nickel to give 4-(o-cresoxy)-butane diol (1.2); phenol, xylenol, mono- and poly-chlorphenols, or 2-naphthol may be used instead of o-cresol; (b) mercuric sulphate is added to a mixture of resorcinol, butine(2)-diol(1.4) and tetrahydrofurane; the mixture is heated, neutralized with calcium carbonate and filtered; the filtrate is hydrogenated in the presence of Raney nickel to give resorcinol bis-(1.2.4-butane triol) ether of formula <FORM:0714617/IV (b)/1> instead of butene(2)-diol(1.4) equivalent amounts of pentine(2)-diol(1.4) or hexine(3)-diol(2.5) may be used.

Abstract: 1,242,331. Laminated light diffuser; injection moulding. IMPERIAL CHEMICAL INDUSTRIES Ltd. 23 Dec., 1969 [3 Jan., 1969], No. 476/69. Headings B5A and B5N. A light diffuser comprises a foamed core of clear methyl methacrylate polymer and surface skins of translucent opalescent methyl methacrylate polymer. The polymer may be a homopolymer or copoly (methyl methacrylateethyl acrylate) and the skins may include opacifying pigments. The diffuser may be made by injection moulding in a vertical flash mould. A charge of skin material is first injected into the mould, and before this has set, a charge of core material containing a blowing agent (which may be liquid or solid) is then injected, preferably through the same orifice, and the material is allowed to foam and set. Preferably a second charge of skin material is injected after the core material to avoid exposing the core on removal of the sprue. The core material is preferably injected at foaming temperature but at a speed and pressure that prevent foaming until the mould is filled, the mould cavity then being enlarged to allow foaming.

Title: Improvements in or relating to belt conveyers
IPC: B65G39/16
Filed: 1961-01-05
Abstract: 898,520. Endless belt conveyers. CORNISH, F. R. H. Jan. 5, 1961, No. 541/61. Class 78 (1). The lower run of a conveyer belt 1 is centralised by a roller unit 6 on either side of the belt, each roller 7 having a helical groove 11 slightly wider than the thickness of the belt. The surfaces of the rollers are preferably of rubber. When lateral displacement of the belt is sufficient to cause the belt to engage the lower end of the groove 11 of a roller 7, the roller is rotated and the belt edge raised. The belt thus tends to move away from the roller and is centralised.

Title: Improvements in and relating to machines for testing tubes
IPC: G01M3/02
Filed: 1952-01-08
Abstract: 706,878. Testing hollow-ware by fluid pressure. SCHLOEMANN AKT.-GES. Jan. 8, 1952 [Jan. 15, 1951], No. 555/52. Class 106 (2) A sealing means for use in machines capable of subjecting tubes to fluid pressure tests, comprises two axially movable rings 1, 2 rigidly connected together, one forming an abutment for the end of a tube under test and the other serving at a ring for pressing against and deforming a packing ring 11 bearing against a stationary counter-pressure ring 10. As shown, the ring 1 is part of a hollow cylinder 3 on which is screwed the ring 2. The ring 1 is formed with recesses 8 through which legs of the counter-pressure ring 10 are passed to bear against fixed means 4. When the tube is pressed against the abutment ring 1, or, conversely, when the ring 1 is pressed against the tube, the ring 1 together with the cylinder 3 and the ring 2 are moved towards the fixed means 4 against the action of a spring 5. This movement causes the packing ring 11 to be compressed between the rings 2 and 10 and to bulge outwards with a sealing effect against the inner wall of the tube. The arrangement may be modified to cause the packing 11 to grip the outer wall of the tube.

Title: Improvements in chucks for holding drills, taps, reamers and like tools and bars
IPC: B23B31/12
Filed: 1922-01-07
Abstract: 196,031. Clare, C. H. Jan. 7, 1922. Addition to 129,241. Chucks.-In a chuck of the type described in the parent Specification, one or both of the screw-threads are replaced by helical grooves containing balls. The left- and right-hand threads on the split sleeve d, and shank a respectively, Fig. 4, are replaced by helical grooves containing balls. The shank may be tubular to admit bar stock, for example when used in turret-lathes. In a modification, the right - hand helical groove b, Fig. 1, contains balls and the lefthand thread c is of the usual form, the sleeve d being provided with radially movable jaws e and with a stop d<2> which coacts with a stop e<1> on the shank to limit the opening of the chuck. Screws m in the cap g engage slots in the sleeve to prevent relative rotation, so that when the tool encounters resistance they both rotate relatively to the shank and move axially in opposite directions. The screws may be replaced by a hand-actuated device. In a further modification, the groove is left-handed and the thread right-handed, the direction of the taper on the cap and sleeve is reversed, the thread may be replaeed by a ball-race, the tool abuts against either a solid end on the sleeve or a screwed-plug inserted therein, and the plug or sleeve may be provided with a slot to engage the flat end of the tool.
Patent GB-112627-A (GB)
Title: Improvements in and relating to Machines for Making Eye-members of Snap Fasteners.
IPC: B21D53/48
Filed: 1917-03-26
Abstract: 112,627. American Fastener Co., (Assignees of Kiessling, M. F.). March 17, 1916, [Convention date]. Fastenings; springs. - A machine for making the female members of snap-fastenings or press-buttons comprises means for cupping the fasteners from strip stock, a loop return guide for reversing the strip prior to blanking out the cupped fasteners, and a dial plate for transferring the fasteners to spring-inserting, beading, and ejecting stations. The springs are made in the machine from wire stock. All the parts of the machine, except the slitting- saws, are driven from the crank-shaft 4 that reciprocates the press heads 18, 59. The various motions are derived from the cam shafts driven by the bevel-gearing shown in Figs. 1 and 2. The shaft 11, Fig. 2, actuates a worm and ratchet drive 97, 93 for feed-rolls 35, which draw strip stock beneath cupping-punches 22, 23, 24 to form the sockets 29, Fig. 7, a gang punch 30 which forms the sewing-holes 34, and a planishing- punch 31. The slots at the base of the sockets to receive the legs of the springs are formed by a pair of slitting saws 37 driven at 98. The strip then passes through a loop return guide 42 formed in the table 39, and is fed to a cutting-out and cupping punch 35 by a pawl 44 reciprocated by a cam 48. The stepped die 52, Fig. 10, is carried by a bridge-piece 51 spanning an annular dial plate 40 having a series of apertures. The punch 53 first cuts out a circular blank, and the punch 54, hollow to admit the socket 29 and actuated by the separate head 59, then cups the blank and forces it into a recess 41<1> in the dial, which is a frictional fit for the blank and acts as stripper for the punch. The pawl 60, Fig. 2, for indexing the dial is mounted on a reciprocating bar and carries a cam 65 for retracting the spring- controlled locking-bolt 64. A concave die 73<1> bends a length of wire round a mandrel 69, levers 72 then close the wire laterally round the mandrel, and the cam 78 advances a die to form the reverse bends. The dies then retire, and the mandrel is withdrawn, leaving the spring seated in a recess in the carrier slide 79, which is then advanced to bring the blank below a punch 82, Fig. 1, situated over the second aperture of the dial. The punch 82 transfers the spring from the carrier into the cupped blank. The third aperture of the dial is located over a punch 85, Fig. 13, and beneath a die 87 fitted with an ejector 89. The punch 85 and ejector 89 are connected by levers 91, Fig. 2, actuated successively by a common cam 92. The punch forces the blank up into the die, beading the edge to retain the spring as shown in Fig. 7, thus completing the fastener. The ejector returns the fastener to the dial, in which it is now a loose fit, and falls out of a discharge opening when the dial again moves.
