Title: Improvements in and relating to machines for corking bottles
IPC: B67B1/04
Filed: 1926-02-11
Abstract: 250,516. Holstein & Kappert Maschinenfabrik Ph÷nix Ges. April 27, 1925, [Convention date]. Corking; ' crown corks,' applying.-Relates to a machine for corking bottles and comprising a rotating frame B consisting of a table 13 having bottle rests 10 and an upper table 7 carrying a like number of corking devices 8, the rotating framing B being mounted on a fixed hollow column 2 which supports a fixed framing comprising lower and upper cruciform arms 4, 5 connected by vertical rods 3, and consists in operating the corking-devices 8 by a pressure member 19 adapted to be reciprocated in the upper arm 5 by a lever 23 to which it is connected by links 22. The lever 23 is connected by a rod 24 to a lever 25 operated by a crank pin 28 on a crank disc 27 driven by the shaft which rotates the framing B, the pin 28 engaging in a slot in the lever 25. Corking is effected as the pin moves downward through the half of its path that is the more remote from the pivot of the lever 25, the nearer portion of its travel serving to raise the pressure member 19. The member 19 is depressed each time a corking- device comes beneath it, each movement depressing a roller 17 on a slide 15 which is provided with a guide 16 secured to the framing B and which carries a corking-plunger 14. The slides 15 also carry rollers 18 which are engaged by a fixed guide rail 34 to raise the plungers from the bottles to the member 19 which is formed as a circular arc centred on the axis of the framing B and is of sufficient length to ensure proper application of the corks. A spring may be inserted in the rod 24 and the lever 23 may have its pivot resiliently mounted to avoid fracture of the bottle. The machine may be adapted for applying ' crown corks ' by replacing the cork. ing-devices by crowning-heads and making the stroke of the member 19 adjustable by inserting a tensioning device in the rod 24.

Title: Improvements in or relating to selector switches for telephone systems
IPC: H01H67/12
Filed: 1930-02-06
Abstract: 348,563. Automatic exchange switches. ROSA, A., 13, Via Paolina, Rome. Feb. 6, 1930, No. 4073. [Class 40 (iv).] In a selector wherein the wiper arm receives three different selective movements i n the same plane, two rotary movements are effected in long and short steps respectively, and thus a member is operated to lock the arm against further rotation and render effective means for producing a radial movement. As shown, the wiper arm c, which cooperates with the contact bank a<1>, is mounted on a rack bar d slotted to embrace a shaft b which carries ratchet wheels h, i. A disc f loosely mounted on shaft b carries a pinion g, which meshes with the rack d, and an arm w having a pin f<1> normally engaging a hole in the wheel h. Operation of the ratchet wheel i by the electromagnetically operated pawl o rotates the arm c through long steps, the movement being communicated through pin f<1>, disc f, and pinion g. Similarly short steps are produced by pawl m acting upon wheel h. After the rotative movements, an electromagnet k is energized to attract disc f to lock the arm c against further rotation and withdraw pin f<1> from engagement with wheel h. Further operation of wheel h by pawl m then rotates the pinion g through teeth (not shown) on the part x of the wheel h. These teeth engage a pinion on the shaft of pinion g to drive the arm c in a radial direction into the bank of contacts. The wheel h is stepped against the control of a spring which upon energization of the release magnet q, restores the parts to their normal positions. The pin f<1> is normally maintained in engagement with the wheel h under spring control.

IPC: C06C5/00
Filed: 1927-02-15
Abstract: 295,730. Fritzsche, J. Feb. 15, 1927. Blasting fuzes.-Safety blasting fuzes are made with a core of powder in which the reactive ingredients are less intimately in contact than in ordinary black powder. The powder may comprise potassium nitrate and charcoal with or without sulphur (a) prepared by mixing or by mixing, wetting, and drying, but not pressing; or (b) having in loose condition a density less than water, obtained by fineness of grinding, or by increasing the proportion of lighter ingredients, or by the addition of light inert material such as Meselguhr or magnesium carbonate; or (c) mixed with a diluent such as charcoal or finely divided pumice or kaolin. The potassium nitrate may be replaced by another nitrate, the sulphur by sulphide, and the charcoal by a carbonaceous substance such as dextrine or starch. The powder is fed in loose condition, preferably in conjunction with stirring means, and a paper strip conveyer. The powder may be covered by materials such as paper, metal foil, kaolin, talcum, or cement, which are non-pervious or pervious with difficulty to the gases of combustion; or the paper covering may be perforated or have an open texture so as to be pervious to a slight extent to these gases. The powder may be treated as described in Specification 295,406.

Abstract: 1286593 Grinding; drills OMARK-WINSLOW AEROSPACE TOOL CO 29 Jan 1970 [4 Feb 1969] 4396/70 Headings B3C and B3D Apparatus for supporting, e.g. a drilling or reaming bit for grinding comprises a base 38, a cross-slide 44 transversely movable on the base 38, a workpiece-bearing slide 40 movable across the slide 44, and means 42 for selectively moving the cross-slide 44 while maintaining the workpiece slide 40 fixed relative thereto, moving the workpiece slide 40 on the cross-slide 44, with the latter fixed relative to the base 38, or moving both slides simultaneously. The workpiece W is supported on a spindle 20, rotatable in a housing 18 supported on the slide 40, by means of a hand wheel 22 or belt drive 24. A cam 32 is fixed to the spindle 20, and acts against a roller 76 bearing on a second roller 96. The roller 76 is rotatable on a lever 71, pivoted at 72 to an extension of the housing 18, and a movement of the roller 76 against the cam 32 pivots the lever 71 about an adjustable fulcrum 80 acting on a fixed abutment rail 82, resulting in transverse unitary movement of the slides 40, 44 on tracks of the base 38 against a return spring 58. For movement of the slide 40 on tracks 62 of the cross-slide 44, movement of the roller 96 is transmitted through a lever 88, 94, pivoted on a fixed post 92, to a member 98 adjustable along one arm 88 of the lever, which member 98 acts directly on the slide 40 to move it axially against a return spring 70. Adjustment of the fulcrum to a position adjacent the pivot 72 inactivates transverse movement of the slides 40, 44, while positioning of the member 98 adjacent the post 92 inactivates axial slide 40 movement, suitable relative adjustments allowing any required composite movement. An exemplary stepped diameter drill bit, Fig. la, includes a portion 1 of reduced diameter.

Title: Hexaformed bamboo honeycomb panel structure
IPC: B27D1/06
Filed: 1960-02-09
Abstract: Bamboo or other strong reed-like material is softened by hot water or steam and then compressed into hexagonal section round a hard hexagonal insert fitting loosely inside each piece.  Bamboo cut from between joints is graded according to wall thickness, inner diameter and length and the wall thickness, if excessive, is reduced by reamering.  Selected batches, after softening, are laid parallel to each other in a frame which is an adaptation of a baling machine, the hexagonal inserts are placed in each tube and pressure is applied by hydraulic or screw means until the softened bamboo tubes have adapted themselves to the hexagonal shape.  The mass, still tightly fastened, is removed and dried in a kiln or in the sun, the hexagonal inserts being removed during the drying.  When dry, the tubes are loosened, coated with adhesive and bound together again in a mass parallel to each other or laid end to end with staggered joints, as in bricklaying, until the desired length and width is obtained.  The adhesives are preferably phenolic, epoxy or resorcinol resins. Chemical fungicides may be added during the hot water immersion.  The honecomb material formed from the tubes is adhered between sheets of wood, plywood, metal or plastic after being sawn, if necessary, to the required dimensions.

Title: Improvements in Controllers for Alternating Current Motors.
IPC: H02P25/26
Filed: 1918-03-14
Abstract: 119,615. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). March 14, 1918. Systems for alternating-current motors only.- A controller for alternating-current motors has reversing-means and accelerating-means operated by an alternating-current motor and held by that motor against return movement. The working- motor M is connected to the three-phase leads L, L<1>, L<2>, by reversing-switches 1, 2, and the resistances R, R<1>, R<2> in the rotor circuit are controlled by the switches 10 - - 12a. The alternating-current torque-motor M<1> actuates a shaft 3 with cams 4, 5 which operate the switches 1, 2 and permit the shaft to rotate after one of the switches has been closed. Further rotation causes the accelerating-switches 10 - - 12<a> to close in pairs by the operation of the shaft 16 subject to the delaying action of a dash-pot 21. A link 19 joins cranks 20, 17 on the shafts 3, 16, the crank 20 and link 19 being arranged so that the accelerating-switches close when the shaft 3 is rotated in either direction from its zero position. The motor M<1> is started by a hand-reverser 26 and operates one of the reversing-switches 1, 2 and then the accelerating-switches. The torque exerted by the motor M<1>-holds all the main motor switches closed against the action of the spring 24. Should a phase reversal of the line occur, the motor M<1> would reverse to close the reversing- switch which is normally open under the conditions existing, so that the main motor M will always run in the same direction for a particular position of the master switch 26.

Title: A new or improved apparatus for distributing the odours of perfumes, disinfectants and the like
IPC: A61L9/12
Filed: 1923-02-19
Abstract: 212,722. Vickers, H. Feb. 19, 1923. Vaporizing by air currents; vapours, delivering. -Apparatus for distributing the odours of liquid perfumes, disinfectants, and the like in public buildings and rooms comprises a fan rotating in a casing having a tubular inlet to which discharge pipes from vessels containing perfume &c. are led, the main air-current created by the fan inducing a current of air through the perfumevessels. Provision is also made for varying the amount of the induced air-current or for cutting it off. The fan b rotating in the casing a draws air through the tubular inlet e and discharges it at d. Tubes f from one or more vessels h containing perfume &c. are led to the inlet e and are arranged so that the main air-current passing through the inlet induces a current of air through the inlet-tubes i and outlet-tubes f of the, vessels h. The amount of the induced air-current may be regulated by means of a rotatable ring m fitting round the inlet e and having holes n registering with radial ports on the inlet. The inducing action of the main air-current is destroyed when the ring is adjusted so that the ports are fully open. An alternative method of adjustment consists in providing the inlet pipes i with a valve operable from outside the vessels h. For example each tube may be provided with a triangular hole p capable of being covered by a slide q operated by means of a handle r. The extent to which the hole is uncovered determines the amount of the induced air-current.

Title: Improvements in or relating to spring clutch mechanisms
Inventor: SACCHINI COLUMBUS RAINER
IPC: F16D13/02
Filed: 1958-02-14
Abstract: 834,505. Friction clutches; ratchet clutches. CURTISS-WRIGHT CORPORATION. Feb. 14, 1958, No. 4895/58. Class 80 (2). A clutch in which torque is transmitted through a helical coil spring in frictional engagement only with its driving and driven members, introduction of a stop into the path of a shoulder fast with the driving end of the spring causing clutch disengagement, has the coils of the spring engage the driven member more firmly than they engage the driving member when the clutch is stationary. Accordingly, when the clutch is disengaged during drive transmission, overrun causes the clutch spring to be completely disengaged from the driving member. Excessive vibration and wear of the clutch spring are thereby avoided. The clutch spring may be expanded to grip the inner periphery of surrounding driving and driven members, but in the form shown, a driving drum 1 and a relatively rotatable driven drum 11, comprising the hub of a pulley 5, can be clutched together by a surrounding helical coil clutch spring 20. The end coils 20d of the clutch spring are, when in the unstressed condition shown in Fig. 3, of smaller diameter than the coils 20a which grip the driving drum 1. A projecting tab 20c on the coil spring engages a rotary sleeve 22 having a radial projection 24 which can be engaged by a stop (not shown) to hold the sleeve stationary; overrun of the driven drum 11 then unwinds the coil spring 20 from the driving drum 1 and disengages the clutch. The helical coil spring may alternatively be engaged more firmly with the driven drum 11 than with the driving drum 1 by making its end coils 20d of thicker wire than the remainder of the coil, or by making the driven drum of slightly greater diameter than the driving drum and using a coil spring of uniform diameter, or by having a coil-loading split spring band surrounding the coils of the spring at its driven end.

Title: Improvements in or relating to conveyor mechanism
IPC: B65G47/68
Filed: 1931-02-17
Abstract: 356,648. Endless chain conveyers with articles hung on hooks. WHITE, A. E., 5, Quality Court, Chancery Lane, London.-(Morgan Construction Co. ; 15, Belmont Street, Worcester, Massachusetts, U.S.A.) Feb. 17, 1931, No. 5063. [Class 78 (i).] In a conveyer system in which articles are fed at a number of points into the path of hooks carried by an endless chain, a transfer device is arranged at each feeding point which operates in the presence of an article and on the approach of a hook, only if the said hook is not engaged with an article taken from a preceding feeding point. Each hook 6 is mounted on roller supports 7 connected to form an endless chain, and travels in a groove 5 in a platform 4. Articles, such as coils of wire a, are transferred from a platform 13 to the platform 4 by a pair of pivoted arms 29, and are delivered to the platform 13 by lugs 8<1> on the feeding conveyers 1, 2, 3. During the transfer of an article to the platform 13, it moves a pivoted arm 14 and opens a switch 16 and closes a switch 15. The opening of the switch 16 stops the drive of the feeding conveyer, and this cannot be resumed until the removal of the article allows the arm to return to its initial position. The circuits containing the switches 15 are connected in parallel across the leads 17, 18 and include normally-open switches 19 disposed above the platform 4 and adapted to be closed by the action of a hook on an arm 20. Each circuit, except the one associated with the conveyer 1, contains also a normallyclosed switch 21 which is opened by the action of an article on a movable arm 22. When each switch 15, 19, 21 is closed, a solenoid 23 is energized thereby releasing a latch 26 holding a weighted arm 27 attached to the arms 29. The descent of the arm 27 causes the arms 29 to move to transfer the articles to the platform 4. The arm 27 is returned to the position shown in Fig. 3 by a link 33 actuated by an eccentric 34 on the shaft of the sprocket 12.
