Title: Improvements in machines travelling in the body of a fluid
IPC: B64C33/02
Filed: 1936-01-30
Abstract: 462,205. Vibratory propeller. OGER, G. Jan. 30, 1936, No. 2870. [Class 4] A machine intended to travel in the body of a fluid comprises an engine driving propelling means and surfaces subject to the relative current of fluid, the surfaces having a fixed front portion and a movable rear portion hinged thereto about a transverse axis, the movable portion being adapted to receive by mechanical means a rapid movement of vibration of large amplitude. As applied to an aeroplane having a tractor airscrew 2, Figs. 1 and 2, driven by an engine 3, the wings comprise a fixed part 4 and a part 5 hinged to a transverse axle 6, the rigging angle of incidence of part 4 being substantially zero. Axle 6 carries floating levers 7, 8, Fig. 4, adapted to be coupled selectively to axles 6 by means of a sliding sleeve 21. Lever 7, Fig. 1, is connected by a spring 70 to an arm 77 of a lever 110 loosely mounted on axle 6 at its upper end and engaging a rack 111 at its lower end. Lever 110 also carries stops 11, 12 limiting the amplitude of vibration of wing member 5. Lever 8, Fig. 2, is slotted for the engagement of one end of a bell-crank lever 14, Fig. 2, reciprocated by means comprising worm gearing driven either from engine 3 or by an auxiliary engine. The pivot bearing of lever 14 is displaceable along a guide 19 to vary the amplitude of vibration of wing parts 5. At take-off, wing parts 5 are vibrated at high speeds and at maximum amplitude, for high speed flight the amplitude is progressively decreased and the speed of vibration reduced, e.g. by slowing down the auxiliary motor, and finally coupling member 21 is moved laterally to engage lever 8, wing part 5 then vibrating under resilient control in accordance with the action of the wind forces. In the case of engine failure the wing part 5 may be given a large mean incidence by moving lever 110 along rack 111. Axle 6 may be divided so that each wing portion may vibrate separately, the axles being coaxial, parallel, or oblique. According to a modification, the wing portions may be vibrated by fluid transmission gear. The invention may be applied to the elevators and rudders of aeroplanes, dirigibles, and submarines, or to blades or sustaining screws of helicopters and gyroplanes. In the last mentioned application the vibratory motion may be produced during rotation of the screw by cam means.

Title: Improvements in or relating to a method and apparatus for coating metals by dipping
IPC: C23C2/00
Filed: 1940-02-16
Abstract: 538,805. Coating metals. WEAN, R, J., and THEISS, H. W. Feb. 16, 1940, No. 3027. [Class 82 (ii) ] Sheet metal is passed through a pre-heating bath of non-coating metal and then through a bath of coating metal floating on the first bath with a relatively small area of contact, and means are provided for removing the dross from the bottom of the coating metal bath and delivering it to a bath of coating metal deeper than the coating bath. A container 10 for molten metal is heated by combustion gases from burners 12 passing through side flues. A cross wall 14 separates a reservoir 15 for spelter from the main container for lead. The reservoir 15 is heated by radiating tubes 16. A flux box 22 is arranged between sheet-handling rolls 18, 19. The lead and zinc are separated by a baffle 23 except for an area adjacent to the exit rolls 20. The sheets are preheated by passage through the lead bath and are coated by passage through the zinc. The temperature of the zinc may be above or below that of the lead. A driven paddle 30 is provided to withdraw metal from the bottom layer above the baffle 23 so that any dross therein is allowed to sink to the bottom of the reservoir 15. A modified form suitable for coating strip is described, Fig. 4, not shown. The lead bath is heated by combustion products from separate burners, passing through heat exchange tubes immersed in the metal or by radiation from heating tubes above. Guide rollers are mounted on cranked arms so that they may be raised to facilitate threading the strip through when starting. Heat radiating tubes are provided adjacent the strip as it emerges from the coating bath, and the strip passes upward through a tower in which a non-oxidizing atmosphere is maintained. The metal container may be covered, and a non-oxidizing atmosphere maintained in it. The passage of the strip through the tower subjects it to heat treatment for a definite time. Galvanized steel strip is found to contain about 1 per cent. of lead in the coating. A dross-removing paddle is provided as in Fig. 1. In a modification for coating wire, additional guides may be provided in the zinc bath to lengthen the time of immersion of the wire.

Title: Improvements in or relating to tuning means for wireless receiving apparatus
IPC: H03J5/12
Filed: 1938-02-01
Abstract: 510,360. Adjusting wireless apparatus. GENERAL ELECTRIC CO., Ltd., BLOCH, A., and WELLS. G. M. Feb. 1, 1938. No. 3137. [Class 37] [Also in Group XL] In a wireless receiver having mechanical press-button tuning, the final setting of the tuning shaft is accurately determined by secondary locating means, automatically brought into operation by mechanical means before the operating member reaches the end of its travel. Thus in Fig. 1, the member 3, actuated by the press-button 10, carries a pin 8 engaging a heart-shaped internal cam in a disc 2 secured to the tuning spindle 1. The final locating means is a narrow slot 14 into which the pin 8 drops to determine exactly the setting of shaft 1. The cam may be engaged by a roller, mounted on the pin 8, until close to the slot 14 where the cam has a stepped portion so that the roller rides clear and the pin 8 itself completes the final positioning. In the modification of Fig. 4 the hinged member 3 actuates the uppermost of two sliding racks 18, 19 engaging a pinion 17 on the tuning shaft 1, the positioning being completed when 3 engages both members 20 and 21. Just before this point is reached, lever 3 rotates lever 23 to engage 25 with the slot 26 in member 27 which is integral with the pinion 17. The final position of shaft 1 is thereby accurately determined. In all cases, operation of a press-button operates the wave range switch to the corresponding waveband, if such band is not already switched in, by means of projections on the press-button shafts, engaging one or other side of a rectangular frame rotatably mounted and coupled to the wave-range switch spindle, Fig. 5 (not shown). The Provisional Specification describes also a push-button control in which the lever operated by the button is coupled to the tuning shaft by a pair of cords, two ends being secured to the lever and two to one point on the periphery of the spindle. Specification 405,716 and U.S.A. Specification 1,846,289 are referred to.

[Class 125 (iii)] A plug or inside fitting lid for a can or like container comprises a cylindrical wall 1, Fig. 1, by which it frictionally closures the can, a flange 5 at the top of the wall, and an inwardly extending groove 3 disposed in the wall 1 beneath the flange 5, the latter being depressed at one or more places 9, Fig. 4, to form stops which engage the mouth of the can and space the lid therefrom so that an opening tool such as a coin inserted in the groove is disposed inside the wall of the can 2 and the cylindrical wall 1. The can wall is beaded at 4 while the flange 5 is provided with an outward peripheral curl 6. The lid may be corrugated concentrically while the can body may be grooved inwardly at 8 to form a seating for the lid. To ensure an even seating, the flange 5 is formed with three depressions 10 forming stops 9. If desired, the lid may be hinged to the can body, a hinge pin 11 on the can, Fig. 5, co-operating with a curl 12 on the lid formed preferably where the flange is displaced to act as a stop. In alternative forms, the hinge pin is formed by slotting the can wall, or the flange above the groove 3 may be inwardly curled at 15, Fig. 7. A rubber ring or other sealing medium may be provided in the groove 3, or in a second groove formed in the wall 1 preferably at its lower edge, to form a hermetic seal.

Abstract: 1379974 Television CLARKE CHAPMAN Ltd 24 Jan 1973 [25 Jan 1972] 3355/72 Heading H4F In an aid to the alignment of two objects, e.g. a pipe end 10, Fig. 5a, in a heat exchanger and a workpiece or plug 52, one object, e.g. 52, has two television cameras 54, 56 coupled to it with their viewing axes intersecting at the desired position of the centre of the pipe end. The two views of the pipe end are displayed on a television monitor using a split screen technique. The left half of the display shows the left half view of camera 54 and right half of the display shows the right half view of camera 56. With the direction of frame scan of both cameras 54 and 56 being both towards the letter T, i.e. with the line scans into the figure, the display is as shown in Fig. 5e when the desired alignment is achieved. Lateral movement of the object 14 and cameras 16, 18 causes one half of the display to move up and the other half to move down to give the displays shown in Fig. 5 (c, d). In an alternative method, the frame scan of camera 76, Fig. 6a, is into the figure, and that of camera 74 is out of the figure. This gives the displays shown in Figs. 6 (c, d, e) with the images of the pipe end approaching each other and merging for alignment.

Title: Improvements in initial puff mechanism for glass blowing machines
Filed: 1922-02-07
Abstract: 194,889. Haddan, R., (Corning Glass Works). Feb. 7, 1922. Blowing. - Relates to the blowing machine described in Specification 21611/12 and consists in providing means for actuating the air pump of the machine in such a manner as to give the initial puff to the parison either while the frame is still in the marvering position or before any substantial movement has taken place. The machine comprises a blow-pipe frame 1, Fig. 1, which oscillates about a bearing 4 and carries an air pump 18 the piston 20 of which is pressed forwards by a spring 19. As the frame swings from the horizontal position shown. in which the parison is marvered, to the vertical position, in which the parison is blown, a number of cams 8-12 and projections 13-15 on a stationary plate 7 reciprocate and rotate, respectively, a rod 24 so that it withdraws the piston 20 and releases it several times, thus imparting to the parison a succession of air puffs to cause it to expand. In the position shown, an arm 27, secured to the rod 24, rests on a plate 36 that lies in a recess in the plate 7. This plate is kept in the recess by a spring 40, Fig. 2, but can be raised above the surface of the plate 7 by means of an arm 34 of a rock shaft 32, another arm 33 of the shaft being provided with a roller 35 that rests on a cam disc 6. When the machine is operated, the motion of the disc 6 carries a stud 5 beneath the roller 35 thus raising the arm 34, and therefore the arm 27 and the rod 24. This momentary movement of the rod 24 releases the piston 20 and an initial puff is imparted to the parison while it is still in the marvering position.
