Title: Method of and machine for the production of gaskets for closure caps, particularly for bottles
IPC: B21D51/46
Filed: 1938-06-20
Abstract: 503,380. Assembling gaskets in closure caps ; cutting gaskets. TIESCH, M. June 20, 1938, No. 18247. Convention date, Nov. 13, 1937. [Class 125 (iii)] [Also in Group ]VIII Gaskets for closure caps for bottles are severed, in the immediate vicinity of the place where they are united to the caps, from a continuous column of material having a cross-sectional shape corresponding to the shape of the gasket. A column of gasket material 16 in the tube 15 is prevented by internal ribs from rotating, but is fed forward by means of a threaded nut 18 at the bottom of the tube. As the shaft 2 is rotated the cam 54 swings the roller 53 and its lever 50 against the action of a spring, to rock the arm 45 on the shaft 43 so that a pawl 46 carried by the arm operates the ratchet wheel 44 which is fixed to the shaft 43. This motion is transmitted by the gear wheels 42, 41 and the sleeve 19 to the nut 18 to feed the material. When this motion ceases owing to the formation of the cam 54, the lever 35 is moved downwards by the cam 37 and a pivoted fork lowers the conical ring 27. This forces the arm 24 outwards and swings the cutter 26 to sever the protruding part of the gasket material. The severed gasket 28 drops into a recess 13 in the disc 11 which is then rotated by the engagement of a roller 7 in one of the recesses 8 in the feed disc 9. As the discs 9, 11 rotate, fresh gaskets are cut and dropped into the recesses and are carried forward beneath a container 56 which is provided with valves 59. An adhesive is placed in the container and this is heated by means of an electric resistance. The valves are operated by means of the cam 66 on the shaft 2 to enable adhesive to be supplied to the gasket beneath the container. As the discs rotate still further each gasket in turn is brought to a position above the piston 76. Closure caps 85 are delivered, by a current of air, through the feed conduit 84 and the end cap is stopped by the pin 86 in the correct position to receive the gasket coated with adhesive when the piston 76 is raised by the cam 66 on the shaft 2. The finished caps pass down a shoot 87 to a receiver. Instead of supplying adhesive to the gaskets paper discs coated with heat-sensitive adhesive may be applied to the gaskets by'a heated plunger.

Title: Forage harvesters
IPC: A01F29/16
Filed: 1972-04-25
Abstract: 1425584 Chopping rotor ARCHIE KIDD Ltd 17 April 1973 [25 April 1972] 18374/73 Divided out of 1425583 Heading A4C In a machine such as a forage harvester, into which a crop is fed and cut, the chopping rotor 16, powered by the p.t.o. shaft of the towing tractor operates against a stationary adjustable ledger plate 54. Overload devices such as grooves in the chopping blades and shear bolts in the ledger plate assembly protect the machine from serious damage in the event of abnormal shock loads. The chopping rotor 16, mounted on shaft 37, carries six blades 42, mounted helically and supported on cross-bars 44 between two scallopped and gussetted cheek plates 38. Opposite the outer cutting edges of the blades is a streamlined member 46 to assist smooth air-flow from the centre of the rotor. Along each blade, adjacent the support bars 44 is a groove or neck 48, providing a convenient fracture line in the event of abnormal stress. The rotor 16 operates in a casing 50 with crop inlet and outlet openings. Casing 50 is sectional and varies in thickness so that sections most likely to be damaged by hard objects picked up by the harvester are accessible and may be replaced easily. The blades 42 operate against an adjustable ledger plate 54 (forming part of a two-part assembly 56) which is attached to the upper arm of an L-shaped member 67. The lower arm is rigidly fixed to a U-shaped assembly with arms 68 and a lower cross-bar 80, the whole forming the first part of the assembly. This portion is carried by a pivot bar 70 which is supported between the flanges 72 of the second part of the assembly which has a reinforced back 75. This pivot support is bolted to the sides of the harvester by shear bolts 74. A compression spring 78 carried on a pin on the pivot support back 75 and passing through a hole 79 in cross-bar 80 biases the ledger plate 54 towards the chopping blades 42, and is restrained by adjustable set screws 82 tapped in plate 75. In the event of a severe shock overload, bolts 74 shear, permitting assembly 56 to fall, thus minimizing damage to the rotor. To prevent assembly 56 from being thrown into the compressing roll mechanism in this event, a heavy plate 76 is mounted across the walls of the feed chamber.

Abstract: 1,180,863. Cross-linkable copolymers for treating textiles. CIBA Ltd. 18 April, 1968 [24 April, 1967], No. 18452/68. Headings C3P and C3R. [Also in Division D1] Copolymers suitable for use in the finishing of textiles contain (a) 80-90% by weight of units of an ester of a mono-(C 1 -C 3 . alkyl) ether of a polyethylene glycol of molecular weight 300- 1000, and an ethylenically unsaturated carboxylic acid, (h) 5-10% by weight of units of an N-methylol-amide, which may be etherified, of an ethylenically unsaturated carboxylic acid, and (c) 5-10% by weight of units of an ethylenically unsaturated compound containing at least one acid group. The acid moiety of components (a) and (b) may be acrylic, methacrylic, crotonic, itaconic or maleic acid; component (c) may be acrylic, methacrylic, vinyl sulphonic, crotonic, itaconic, maleic or styrenesulphonic acid, or hexahydro-1,3-diacryloyl-5- sulphopropionyl - s - triazine or hexahydro - 1 - acryloyl - 3,5 - disulphopropionyl - s - triazine. The copolymers can be prepared by polymerizing the corresponding monomers in aqueous solution or emulsion (e.g. using a sulphonate or a sulphate ester salt as emulsifier) in the presence of a catalyst such as a redox combination of potassium persulphate and sodium metabisulphite. To avoid premature cross-linking, the pH of the monomer composition is adjusted to a value of from 5 to 7À5, e.g. with ammonia or alkalihydroxide; alternatively, monomer component (c) can be used in the form of a salt. The copolymers can be cross-linked by heating at 130-170‹ C. in the presence of an acid-yielding reagent. In Example 16, a textile-treating composition comprises a solution of a copolymer of the invention together with the sodium salt of phthalic acid mono-octadecyl ester, magnesium chloride hexahydrate, and an aminoplast precondensate selected from 1,3-dimethylol-4,5- dihydroxy - 2 - imidazolidone, methylolmelamine and dimethylolurea.

Title: A machine for gumming and folding envelopes
IPC: B31B70/00
Filed: 1920-07-06
Abstract: 146,977. Dunnebier, M., and Winkler, A. Oct. 19, 1018, [Convention date] Coating-machines.-Relates to machines for making envelopes and consists in combining with a roller folding machine a mechanism for laying- out and gumming the closing-flaps of the envelope blanks. The blanks are stacked on a table 1 and are fed into the machine by an oscillating suction-picker 8 which seizes the point of the flap of the blank at the bottom of the pile. The blank is carried by the picker in between a pair of rollers 3, 4, of which the upper cne, 3, is made in two parts to permit the passage of the picker and each part is segmental so that it feeds the blanks forward intermittently. The lower roller 4 is intermittently rotated by a pawl and rachet. The blanks are fed to the rollers 3, 4 at such a speed that as they leave the rollers, they overlap one another, the edge of each blank being separated from the edge of the preceding one by a space which is to be coated with gum. The blanks thus laid out in a long train are fed by rollers 17, 18 to a third pair of rollers 20, 21 rotated continuously, around which pass feed bands 27, 28. The train of blanks is carried by these bands past a gumming-device 29 and fed on to a second pair of bands 30, 31 which run at a higher speed. The blanks are thus spread out slightly to prevent them from sticking at the edges, and while being carried by these bands 30, 31 have the gummed flaps dried by any suitable drying apparatus. After leaving the bands 30, 31 the blanks are carried forward by a band 50 running at a higher speed in order to increase the separation of consecutive blanks. A roller 47 co-operates with the band 50 and has a circumferential recess 51, Fig. 3, which is bridged for a short distance 52. The part of the flap of a blank fed by the bands 30, 31 enters the recess 51 and is arrested until gripped and fed forwards by the part 52. Thus the blanks are fed forwards only at predetermined intervals and the spacing is regulated. The band 50 feeds the blank against straightening fingers 56, which are removed when the blank is to be gripped by the first feed-roll 43 of the folding-mechanism. In front of the fingers 56 is a gum-breaking device for straightening the curled edges of the flaps. This consists of an horizontal rail 62, Fig. 9, having a curved upper edge and a grooved rail 63 journaled in oscillating cranks 64. The rail 63 bends the blank over the rail 62 so that as the blank is drawn by the roll 43, the gummed edges are straightened.

Title: High frequency signalling
IPC: H04J1/00
Filed: 1920-07-06
Abstract: 146,988. Western Electric Co., (Assignees of Heising, R. A.). March 3, 1916, [Convention date]. Multiplex wireless signalling.-Wireless signalling is effected by a high-frequency carrier wave modulated by a wave of intermediate and inaudible frequency which is itself modulated in accordance with the signal to be sent. Multoplex working is obtained by employing several non-interfering intermediate frequencies, and, if desired, several carrier frequencies. The transmitting-apparatus shown in Fig. 1 comprises a high-frequency generator 1 with a frequency of, say, 1,000,000, coupled to a, circuit 2. A number of generators 3 ,3<1>, 3<11> &c., of frequencies, say 40,000, 30,000, 20,000 are connected through thermionic modulators 4 to tuned circuits 6 coupled to the circuit 2. The oscillations generated by the sources 3, 3<1>, &c. are modulated by microphones 5 or other source of audible-frequency signal currents. The modulated oscillations in the circuits 6 modulate the carrier wave in the modulator 7, and are amplified by the relay 9 and transferred to the aerial 10. At the receiving-station, Fig. 2, the waves are received in a circuit 13 tuned to the carrier frequency, and are rectified to currents of intermediate frequencies by the detector 14. These currents are separated by the circuits 15, 15<1>, &c. tuned to the various intermediate frequencies, and are transferred to other tuned circuits 16, 16<1>, &c., which are connected across the grids and filaments of detectors 17 having telephones 18 in their output circuits.
