Title: Improvements in or connected with folding wings for aircraft
IPC: B64C3/56
Filed: 1931-08-27
Abstract: 388,437. Aircraft wings. VICKERS (AVIATION), Ltd. and WALLIS, B. N., Byfleet Road, Weybridge, Surrey. Aug. 27, 1931, No. 24108. [Class 4.] Folding wings for aircraft include detachable wing joints, a double locking-device for each wing, and common operating-mechanism for the double locking-device which is locked or unlocked by a separable key member, not normally forming part of the wing structure. As applied to a biplane in which each wing is provided with two booms a, a<1>, the end piece g of a jury strut g<6> is applied to an extension f<12> of a rotatable sleeve f<2> associated with the operating-mechanism of the upper wing joints, and a spring-controlled slidable-sleeve g<4> is situated at the upper end of, and allows, the jury strut to be raised against the action of the spring until its lower end-piece g<1> can be passed over the end of an extension f<12> of a rotatable sleeve f<2> associated with the mechanism for the lower wing. Rotation of a handwheel h<3> elongates the jury strut through right- and left-handed screw-threads h<1>, h integral therewith engaging similar threads g<14>, g<10> situated respectively on an extension g<13> of the strut and on the end-piece g<1> which is slidable in the extension g<13> and this elongation causes projections g<3> to engage and move apart spring-controlled rods f<9> which are slidably mounted in the sleeves f<2>. This motion frees teeth f<4> on the ends of each rod from corresponding teeth f<5> on the ends of each sleeve f<2>. Rotation of the jury strut by means of another hand-wheel g<15> integral therewith rotates the sleeves f<2> and pinions f integral therewith, which in turn rotate pinions e<2> carried on barrels e<1>. Squared ends d<4> of locking-bolts d, d<1> are slidable in the ends of the barrels e<1>. Housings b<4> are formed with internal right- and left-handed screw-threads b<6> which engage corresponding screw-threads d<2> on the shanks d<3> of the locking-bolts. Consequently rotation of the barrels causes the bolts to be moved towards or away from one another, thus unlocking or locking joints b, c and b<1>, c<1> associated respectively with the upper and lower booms of each wing. An indicator which includes a slidable rod i operated by teeth i<1> integral therewith and engaging teeth i<2> formed on the periphery of a wheel i<3> carried by the sleeve f<2> is provided. The invention may be modified by the introduction of bevel gearing in order that it may be applicable to locking-bolts having parallel axes and the invention may be applied to monoplanes or to constructions with more than two joints on each wing, and in this case a single operating- mechanism for all the joints is provided.

Title: Improvements relating to nozzle assemblies
Inventor: JEPSON MICHAEL DENIS
IPC: F26B21/00
Filed: 1959-07-14
Abstract: 895,234. Making nozzles. SPOONER DRYER & ENGINEERING CO. Ltd. Oct. 12, 1960 [July 14, 1959], No. 24115/59. Class 83 (2). A method of manufacturing a nozzle assembly for the projection of high-velocity streams of gaseous medium on to material to be treated comprises perforating a flat or curved sheet of metal to provide a set of spaced rows of apertures, bending a plurality of strips of metal into channel-like form and thereafter securing the strips to said sheet to extend in substantially parallel spaced relationship substantially parallel to said spaced rows of apertures with the longitudinal edges of each strip adjacent one side of one of said rows of apertures. In an embodiment a drying cylinder for a paper-making machine comprises a pressure chamber 11 carrying a nozzle assembly 13 consisting of a plurality of channel members 14 riveted or spot welded to an arcuate perforated sheet 15. The round apertures 16 communicate with the spaces 17 between adjacent channel members 14 and the square holes 18 with the spaces 19 within the channel members 14. A gaseous medium is supplied to the spaces 17 and projected through the apertures 16 on to paper on the surface of cylinder 10. Spent gaseous medium is withdrawn at a comparatively low velocity through the exhaust holes 18 into the spaces 19 and then to atmosphere through a hood (not shown) disposed over the pressure chamber 11. Alternatively, side ducts (not shown) at the open ends of the spaces 19 collect the spent gaseous medium. In a modification subsidiary ducts 32 and 33 (Fig. 6) in the channel members and the pressure chamber 11 communicate with the spaces 19 to prevent a predetermined maximum velocity of the gaseous medium being exceeded at the ends of the channel members thus ensuring a small pressure loss in the exhaust system and producing at the surface of the cylinder 10 a pressure slightly above atmospheric which prevents the material on the cylinder 10 from being lifted and damaged.

Title: Improvements in automatic ignition devices for flame projectors
IPC: F41H9/02
Filed: 1928-08-22
Abstract: 296,029. Minimax Ges. Aug. 23, 1927, [Convention date]. Lighting burners by fulminating - pellet and like devices.-A flame projector is ignited by means of friction primers D operated by the jet of liquid fuel from the nozzle N. This jet drives a plunger A up a tube 0, and a flange B at the top of the plunger pulls the tapes L of the primers. The primers set fire to charges M, which transmit ignition to charges G. The heat therefrom melts the solder, which secures the primers in place, and the pressure from the nozzle ejects the piston and the igniters and allows the escape of the jet, which becomes ignited by the charges G. The inner tube 0 is surrounded by an outer tube P lined with asbestos H. A packing disc C is provided at the bottom of the plunger A, and the device is closed against moisture by a cap E. This igniting device may be detached from the nozzle and replaced by a fresh one when desired.

Title: Elastomer-carbon black mix and method of making same
IPC: C08L21/00
Filed: 1944-12-05
Abstract: Rubber-like material is compounded with finely divided carbon in amounts of at least 25 per cent by weight of the rubber-like material by mixing the carbon with an aqueous liquid dispersion of the rubber-like material, coagulating, draining off the liquid and subjecting the coagulated mixture to a mechanised shearing treatment to cause plastic flow while the mass still contains at least 1 per cent of moisture in relation to the content of rubber-like material and before reducing the liquid content of the mixture below 2 per cent based on the weight of the mixed carbon and rubber-like material.  The shearing is preferably effected by moving the coagulum relative to contacting and tightly pressing surfaces or by passing the coagulum between closely set rolls travelling at different peripheral speeds.  The carbon black which may be lamp-, channel-, furnace- or gas-black may be added with a dispersing agent such as sodium lignin sulphonate or the condensation product of formaldehyde and naphthalene sulphonic acid.  The rubber-like material may be polymers of butadiene, 2,3-dimethyl-butadiene-1,3,isoprene, chloroprene, 2,3-dichlorobutadiene-1,3 or copolymers of these substances with styrene, acrylonitrile, acrylates, vinyl pyridine, dimethyl-vinyl-ethinyl-carbinol, allyl chloride and methallyl chloride or olefine polysulphides or linear polyhydric alcoholdibasic acid condensation products.  Zinc oxide and softeners may also be added.ALSO:Rubber-like material is compounded with finely divided carbon in amounts of at least 25 per cent by weight of the rubber-like material by mixing the carbon with an aqueous liquid dispersion of the rubber-like material, coagulating, draining off the liquid and subjecting the coagulated mixture to a mechanised shearing treatment to cause plastic flow while the mass still contains at least 1 per cent. of moisture in relation to the content of rubber-like material and before reducing the liquid content of the mixture below 2 per cent. based on the weight of the mixed carbon and rubber-like material.

Filed: 1946-08-15
Abstract: 625,048. Bicycle handle-bars. PAES, H. W. Aug. 15, 1946, No. 24334. Convention date, April 30, 1943. [Class 136 (iii)] A bicycle handle-bar which can be locked in a position at right angles to the normal position has a union piece 2 connectable with a tubular T-piece 9 mounted on an expander member 8, the union has an extended member 3 which passes through the T-piece and carries on its free end a closure device 12 with an apertured pin 13, an expander bolt 7 passes through the closure pin 13, through the T-piece 9 and apertured part of the extended member 3 of the union, so that on turning the closure device 12 the union 2 is moved towards or away from the T- piece, since the closure pin is immovable with respect to the expander bolt, whilst the apertures 26 in the extended member allow displacement and rotation of this member and of the handlebar. The handlebar 1 has a union 2 provided with teeth 5. The end of a screw-threaded pipe 3 is screwed into the union, the pipe having central apertures 26. The pipe passes through the tubular T-piece the union and T-piece being connected together by interlocking teeth 5 and 10. On turning the closure device 12 the pipe is moved and the teeth move into or out of engagement. A locking pin 15 passes through the closure device 12 to secure in position. The head 11 of the expander bolt 7 is confined in a saddle shaped cover 16 which is immovable, it fits in the T-piece and abuts against the handlebar 1 with a rounded off portion 24. The head of the bolt is enclosed in a keyhole shaped aperture 17 and moves in the slit 18 when drawn to one side. In modifications instead of connection by means of teeth, the union is connected to the T-piece by means of a gutter shaped cross-piece, or by means of a square end of the T-piece fitting into a square hole of the union. The cover 16 may be also replaced by a ring, the head of the expander bolt fitting into a recess.

Title: Improvements in or relating to power transmission gearing
IPC: B66D1/14
Filed: 1929-08-09
Abstract: 337,826. Clarke, Chapman, & Co., Ltd., and Child, G. H. Aug. 9, 1929. Pin and cam-slot gearing.-In cam mechanism for conveying rotation at reduced speed in forward or reverse direction, particularly applicable to lifting-machinery, haulage-plant, capstans, windlasses, lifting-blocks, &c. a driving-member 3, 4 is formed with cam grooves 5, 6 in which engage rollers 16 mounted on pins and carried in radial slots 15 in a stationary member 10, 11 so as to engage the teeth of the driven member 9, all the members being concentric. The number of slots 15 differs by one from the number of teeth, and if in excess the wheel 9 rotates slowly backwards, and if in deficit slowly forwards, as the rollers are moved radially in succession by rotation of the cam member 3, 4. The outer and inner sides of the cam grooves may be offset and engaged by independent rollers on the pins. To assist in rendering the gearing irreversible, part of that portion of the cam slots which forces the rollers against the teeth sides (i.e. the rollers x in the position shown, when the drive is clockwise) may be made concentric and the roots of the teeth undercut. Two wheels with teeth respectively greater and less in number than the number of slots 15 may be driven in opposite directions, their motion being compounded by a differential gear to effect a great reduction in gear ratio. The member 10, 11 may be anchored rigidly or by double-acting spring means to prevent shocks, or may be braked by a mechanically ot electrically operated sheave, which may permit slipping at adjustable overload.

Title: Improvements in or relating to rotary hydraulic shock absorbers and wing shaft assemblies for the improved hydraulic shock absorbers
IPC: F16F9/14
Filed: 1946-08-16
Abstract: 636,670. Rotary hydraulic shock-absorbers. HOUDAILLE-HERSHEY CORPORATION. Aug. 16, 1946, No. 24444. Convention date, Dec. 29, 1945. [Class 108 (iii)] A rotary hydraulic shock-absorber comprises a wing shaft carrying vanes or wings cooperating with a housing assembly to provide working chambers intercommunicating through an axial blind end bore.in the wing-shaft, the bore being closed at the inner end and providing a valve-housing pocket opening towards the outer end of the wing-shaft, a valve body within the pocket having a metering passage for fluid displacement under normal fluid pressure produced by the vanes, and blow-off passages in the valve body controlled by checkvalve assemblies. In the construction shown, in which the section is taken at two planes intersecting in the central axis of the wingshaft at an angle of less than 180 degrees, a housing 12 is divided into four chambers 17, 17<SP>1</SP> (not shown), 18, 18<SP>1</SP> (not shown), by rotatable wings or vanes 11 and 11<SP>1</SP> integral with a boss 58, and two diametrically-positioned, fixed partitions (not shown), integral with an upper wall member 13. The chambers 17, 17<SP>1</SP> are diametrically opposed and constitute compression chambers and communicate through ports 27, 27<SP>1</SP> in the boss 58 with a recess 28 in a valve 25 disposed within the hollow interior 23 of an operating shaft 10 to which the boss 58 is splined. An axial groove 29 in the periphery of the valve 25 forms a metering orifice which connects the recess 28 with a recess 30 in the valve 25 which is connected with the chambers 18, 18<SP>1</SP> (which comprise rebound chambers) by ports 31, 31<SP>1</SP>. The recesses 28, 29 are also connected by blowoff passages 33, 41, having spring-loaded ballvalves 37, 45 controlling maximum compression and rebound pressures respectively. The valve 45 is loaded by a spring 47, the outer abutment of which is axially adjustable by a screw-plug 52 to vary the rebound blow-off pressure. In a modified construction (Fig. 6, not shown), the ball-valves are replaced by semi-spherical members integral with a stepped shankportion on which the valve-loading spring seats. A cover 19 defines with the wall member 13, a reservoir space 20, connected with the working chambers by a ball-valve 21.

Title: Improvements in or relating to multi-speed driving arrangements
Inventor: HALL PHILIP MERRICK
IPC: F16H15/46
Filed: 1958-07-29
Abstract: 868,689. Reverse gear. ELECTRIC & MUSICAL INDUSTRIES Ltd. July 23, 1959 [July 29, 1958], No. 24472/58. Class 80 (2). A gear for driving the capstan roller of magnetic tape transducing apparatus comprises a driving shaft formed with wheels or surfaces of different diameters and carrying frictionally a plate upon which are mounted two idlers, alternatively engageable with driven surfaces on an output member according to the direction of rotation of the driving shaft, to rotate the output member always in the same direction but at different speeds. In one form, a friction wheel 4, Fig. 1, is fast upon a driving shaft 3 which carries by means of a light friction coupling a mounting plate 5 upon which pivot arms 8, 9 carrying idlers 6, 7 at their ends. Rotation of the shaft 3 and the wheel 4 in an anticlockwise direction acts through the light friction coupling to rotate the mounting plate 5 in an anticlockwise direction so that the idler 6 engages between the wheel 4 and a hub 2 of a driven flywheel 1, which accordingly also rotates in an anticlockwise direction. If the shaft 3 and the wheel 4 are instead rotated in a clockwise direction, the light friction coupling turns the plate 5 clockwise to disengage the idler 6 from the hub 2 of the flywheel and instead engages the idler 7 directly with the shaft 3 and also with the-inner periphery of the flywheel 1, which again rotates in the anticlockwise direction but at a much slower speed. The idler wheels 6, 7 may be provided with rubber on their engaging surfaces. In a modification, the driving shaft 3, Fig. 3, carries a drum 15 engaged by a.band 14 connected at its ends by two tension springs 12, 13 to a link 10 pivoting on a pin 11 and carrying upon the arms 8, 9 the two idlers 6, 7. When the driving shaft 3 rotates anticlockwise, the friction between the drum 15 and the band 14 acts through the springs 12, 13 to turn the link 10 anticlockwise and accordingly engages the idler 6 with the wheel 4 and the hub 2 of the flywheel 1. As before, when the driving shaft 3 rotates in the clockwise direction, the idler 7 engages directly with the shaft 3 and with the periphery of the flywheel 1. A link 16 connects the ends of the idler supporting arms 8, 9 so that whichever idler is not driving is held positively out of engagement with its co-operating friction surfaces, thus reducing wear of the parts. To obtain more than two speeds, the shaft 3 &c. may be driven by a multi-speed polechanging reversible electric motor.
