Abstract: 612,189. Rotary wing aircraft. CIERVA AUTOGIRO CO., Ltd., and PULLIN, C. G. May 17, 1946, No. 14943. [Class 4] A rotary wing system comprises lifting and driving components mounted on a common hub-member, the former comprising at least two aerofoil-shaped blades 17, and the latter two or more substantially non-lifting arms 18a, 18b, carrying aero-thermodynamic ducts 19a, 19b, at their tips. In the aircraft shown in Figs. 1 and 3 the arms 18a, 18b are connected to stub arms 21 on the hub 13 by drag pivots 20, and the lifting blades 17 are attached by drag pivots 16 to drag links 15 connected to the hub by flapping pivots 14. Fuel for the propulsive ducts is supplied by a pump 27 to a pipe 29 communicating with transfer pipes 39a, 39b inside the hub and flexible hoses 40a, 40b connected to ducts 41a, 41b inside the arms 18a, 18b. Cyclical and collective pitch control of the blades 17 is effected by a vertical member 44 passing through the hub 13, and mounted on a ball joint on a member 42 engaging the upper end of the hub. Cyclical pitch variation is obtained by rocking the member 44 by links 54, 60 and 55, 61, while collective pitch control results from vertical movement of the members 42, 44 initiated by links 62, 65. The movement of the member 42 relative to the hub is permitted by a pin-and-slot connection 51, 52. Fig. 6 shows a modification in which the rotor hub 31 is mounted on a ball joint 71 at the upper end of a central shaft 30, and the stub arms 21 carrying the driving arms 18a, 18b are attached to a ring 32 mounted on the hub by trunnions 66 whose axis is perpendicular to the driving arms. In this case the fuel pipe 29 is located on the axis of the hub and is connected to flexible hoses 69a, 69b in communication with ducts 70 in the driving arms 18a, 18b. The inclination of the rotor is adjusted by a non- rotating ring 33 which engages with the lower portion of the hub 31. Collective pitch control mechanism for the lifting blades 17 may be provided.

Title: Improvements in or relating to the Reproduction of Patterns on Fabrics.
Inventor: PICCIONI GINO
IPC: D04G3/02
Filed: 1917-10-16
Abstract: 119,905. Piccioni, G. Oct. 16, 1917. Machines for analysing coloured patterns; index setting-arrangements.-In the simultaneous reproduction of a number of copies of a design by drawing coloured woollen threads, selected as described in Specification 29985/13, [Class 142 (iv), Woven fabrics &c.], through the desired number of parallel fabric backings, typographical apparatus is provided for measuring and recording upon a ribbon the tints and lengths of the colour spots on the edges of the cards on which the pattern or design is painted, &c. In this apparatus, the card a, Fig. 4, is inserted in a slot in a frame 2 with its coloured edge uppermost and parallel to a scale 3 for measuring the lengths of the slots of colour and a scale 4 of the colour shades, the scale 4 being movable to effect the matching of the colour. When the shade has been determined, a number indicating it is printed on a ribbon 17 by a die 5 carried by the scale 4, a pressing-block 6, and a hammer 28 actuated by linkwork 27, a spring- pressed plunger 26, and a cam-piece on a handle 7, which is moved about a joint 24 therein to act upon the plunger. Known inking-apparatus may be used, or the ribbon 17 may be of suitable material to be impressed or stamped without ink. The number is printed in the centre of the ribbon 17, Fig. 9, which has previously printed upon its left edge control numbers in progressive order from 10 onwards. When two or more impressions of the same shade number are printed in succession, a numeral indicating the number of impressions is printed simultaneously with the last impression on the right of the ribbon 17, and preferably with a different colour. This is effected by turning the handle 7 to the left until a pointer 8 thereon indicates the desired number on a sector-scale 9. The movement of the handle turns a shaft 12<1> and an arm 12 thereon adjusts a typing- sector 11 to bring the desired die under the ribbon 17 and a pressure table 6a, so that both numerals are printed by the descent of the hammer 28. The sector 11 is locked in its adjusted position by a brake-block actuated by a lever 14, and the brakeblock is withdrawn when the hammer returns to its normal position by a flexible connexion between the hammer and the lever 14. The handle 7 is returned to its initial position by a spring, and through the gearing shown a combined ratchet and cog wheel 19, loose on the axle 20, is turned and acts through a pawl to turn a disk fast on the axle, so that a gear-wheel 22 acts on a rack 23 to advance the holder 2 of the card a and set a new colour opposite the zero of the scale 3 At the same time a wheel 21 on the axle 20 turns the bobbin on which the ribbon 17 is coiled to present a fresh space on the ribbon for printing.

Title: Improvements in or relating to portable, power-operated scraping machines
IPC: B23D79/00
Filed: 1945-06-14
Abstract: 594,435. Scraping. ASPEEK, R. J. June 14, 1945, No. 15064. [Class 83 (iii)] A portable power-operated scraping tool comprises a blade 38 in a holder 36 and a flywheel 21 of substantial mass having an adjustable eccentric crank-pin 32 set at a small angle to the axis of rotation and connected by trunnions 34 to the holder 36 so that the blade is reciprocated, oscillated from side to side and is also rocked to give a " feathered " appearance to the scraped surface. The fly-wheel has a shaft 22 held in spaced ball-bearings 26, 27 by a bolt 24 and sleeves 23, 25 and is driven by a friction cone 20 on a shaft 14 connected to a flexible drive 19. The holder 36 is mounted on a single ball 40 placed between a pair of V-grooves 41, 42 and is held against the ball by springs 43. The blade has an arcuate cutting edge and may be tungsten-tipped; though only one half of the cutting edge operates during the cutting stroke, it is preferably symmetrical to enable the blade to be turned over to use the other half. In a modified form, the eccentricity of the crank-pin imparts the rocking movement and its inclination imparts the reciprocation and' there is no side-to-side movement. A fly-wheel D rotating on an axis eccentric to its axis AA has an inclined crankpin OB which is journalled at O in a link OC passing through a hole in a ball F mounted in a cage on a rod E. The change in position of the angle BOC, which is fixed in size, to the position B<1>OC<1> causes the reciprocation of the rod E and the gyratory movement of the point O causes the rocking.

Title: Improvements in a novel fumigant and method of using same
IPC: A01N59/24
Filed: 1925-06-13
Abstract: 258,324. Buchanan, G. H. June 13, 1925. Fumigants; disinfecting.-A fumigant consists of liquid cyanogen chloride with hydrocyanic acid, in either case prepared so as to give a slightly acid indication with methyl orange so as to avoid decomposition during storage. The acidity is adjusted to 0.01N to 0.025N by the addition of an acid such as sulphuric, hydrochloric, or acetic, or bv the addition of an alkali to reduce excessive acidity to the required value. Mixtures containing less than 50 per cent of cyanogen chloride, and particularly mixtures containing 10 to 15 per cent of this ingredient, are preferred. Commercial hydrocyanic acid containing a small proportion of water may be used. The volatile liquid may be vaporized by spraying, or bv merely placing it in an open dish, or by heating. In treating warehouses, ships, and like enclosed spaces it is preferable to vaporize first a quantity the fumigant sufficient to act as a warning, to persons accidentally present, by reason of its lacrymal effect but insufficient to produce lethal concentration of the vapours, and then after an interval to introduce the full quantity. A mixture consisting mainly of cyanogen chloride may be used for the purpose of the preliminary warning. The Specification refers to the prior use of gaseous mixtures of cyanogen chloride and hydro. cyanic acid prepared by throwing bags containing sodium cyanide and sodium chlorate, with or without talc, into containers of hydrochloric acid and water.

Abstract: 953,680. Vehicle handling devices; reciprocating conveyers. G. PETER. April 19, 1962, No. 15391/62. Headings B8A and B8E. Apparatus for transferring a wheeled vehicle A between two fixed locations is characterized by its means for engaging the vehicle to be moved, the said means comprising a pair of shoes 4, 5, one of which (4) is directly mounted on a carriage 6 and the other (5) on a member rectilinearly slidable on the carriage 6 so that shoe 5 may be moved toward shoe 4 to secure and slightly raise a single vehicle wheel 3. Each shoe is pivotally mounted on an axle 25 or 26 which in turn is pivotable about a perpendicular axle 4a or 5a, respectively, and the shoes preferably are supported by rollers 4b, 5b, respectively. The complete apparatus includes means for moving the carriage 6 along a beam 7 and for moving the beam 7 along a fixed girder 8. The latter may also be laterally movable along transverse supports 9. To move vehicle A longitudinally of the apparatus a chain 10, driven by sprocket 11 and secured at both ends to carriage 6, is arranged to produce the necessary movements of beam 7, carriage 6 and shoe 5. Fig. 3 shows the beam 7 secured against movement by a stop device 16 and the carriage moving to the right along the beam, hauled by the end b of chain 10. When a stop 6a on the carriage strikes a stop 7a near the end of the beam, this rightward movement is halted and a lever 19, struck at the same time, releasesthrough rod 40-the device 16 and also operates a switch 23 which reverses the chain's drive so that the movement-which is now of the beam 7 itself-will continue to be to the right. The grip of the shoes 4, 5 on the wheel is controlled by altering the effective length of the chain through the operation of cylinder 30, Fig. 9. This produces a movement of support member 24 which carries shoe 5 with respect to the carriage 6.

Abstract: 894,971. Electrically-tripped (or released) switches. FILTORS Inc. May 15, 1958 [May 24, 1957], No. 15645/58. Class 38 (5). A relay which is retained in its operated condition by permanent magnetism and reset by energization of a release winding to oppose the permanent magnetism has a rotatable armature in overlapping relation with polepieces in an axial opening in the windings. As shown, magnetic casing 10 engages one pole of a cylindrical permanent magnet 28 which is surrounded by a non-magnetic ring 30 and has its other pole in engagement with a polepiece 14 extending into one end of a bobbin 18 carrying operating and resetting coils 20, 22. A polepiece 16, having a flange extending to the casing 10, also extends into the bobbin 18 with a gap 34 between it and the polepiece 14. The polepieces 14, 16 are slotted to form pole ends 36, 38, 40, 42 with side faces 43 for engagement with the armature 44 mounted on a spindle 46. This spindle carries a nylon actuator 88, reinforced by a plate 90 and having a slot 87 in which a movable contact-spring 85 is engaged. The spring 85 is carried on a terminal pin 80 and biased to engage a fixed contact 84 and maintain the armature 44 against the brass screws 58 which secure the polepieces 14, 16 against each end of a brass spacing cylinder 56. When the coil 20 is energized, the armature 44 is moved to engage the faces 43 and the spring 85 is moved to engage a second fixed contact 83. A discshaped weight 92 held frictionally against the contact actuator 88 by a spring 98 acts to prevent contact bounce in both directions. The magnet 28 retains the armature against the polepieces when the coil 20 is de-energized and its release is effected by energization of the coil 22. The contacts and coil terminations are mounted on pins 77 . . . 82 on glass beads in a metal base 66 which is sealed to the casing 10 and carries a bridge 76 supporting the polepiece 16. The relay may have six contact sets with their springs engaging in slots such as 87 spaced around the periphery of the actuator 88 and one set of contacts may be arranged to change-over the coil connections.
