Title: Improvements in or relating to apparatus for carrying out plucking, stubbing and like operations
IPC: A22C21/02
Filed: 1955-04-13
Abstract: 788,072. Plucking-machines. BUDD, A. G. June 29, 1956 [April 13, 1955], No. 10581/55. Class 28 (2). Feathers are plucked out by being gripped between anti-clockwise rotating blades 5, 6, &c. and a co-operating rubber thumb grip 7 which rocks about a pin 9, so that the first grip is in the position in Fig. 2 and thereafter the grip is increased by the thumb 7 becoming more radial to the axis 4 and then after the feathers are pulled out it releases its grip and then oscillates back relatively clockwise to meet the succeeding blade 6 for the next grip. The rocking movement of the thumb during gripping contact also increases its total speed of rotation to that of the blade itself. The first and clockwise part of the rocking of 7 engages and raises the feathers to ensure gripping by the blade 5. The thumb carrier comprises a sleeve 8, Fig. 1, with end extensions supporting a hinge pin 9 about which the thumb 7 is rocked by a crank-pin 17 and connecting rod 18 to a pin 19. A gearwheel 15 rotates a smaller gear 14 of the crankshaft 13 to give two or more rocking motions to the thumb 7 in proportion to the number of plucking blades 5, 6, &c. on the cylinder 1. A spring 22 tends to pull the thumb 7 clockwise in Fig. 2 to give a quick grip and tends to pull it anti-clockwise in Fig. 5 (not shown) to give quick release after the dead-centre has been passed. A fixed cam path 27 and cam roller 26 held in a web-like crank 25 of the thumb mounting controls the action of the spring 22 so that after plucking the thumb 7 moves ahead of its blade 5. The inwardly directed face 28 of the cam path 27 prevents the thumb 7 from swing- ing outwardly temporarily to avoid blocking the exit of the plucked feathers, but 28 terminates in time to allow the thumb to rock into the next gripping position. This unblocking of the feather exit also allows accommodation for any unwanted solid matter, e.g. the leg of chicken. Specifications 478,081 and 747,355 are referred to.

[Class 122 (i).] In a piston comprising a head 1 of light metal and a skirt 2 of hard metal radially yieldable limbs 4 on one part are connected by casting to the other and are so disposed as to resist relative tilting of the parts due to the thrust of the connecting rod. Two limbs 4, Fig. 3, or two yokes 5, Fig. 6, having their upper ends embedded in the head may be employed. The portions 5<1> of the yokes may be enlarged to encircle the gudgeon pin and form part of the bearing therefor. In a modification one or two chordal struts 8 Fig. 11, formed on the skirt may be embedded in each boss 3 formed on the head and may form part of the bearing for the gudgeon pin. In a further form, Fig. 13, the limbs 9 are cast integrally with the head and encircle the bosses 3<1> formed on the skirt. The flexibility of the limbs permits elative expansion of the parts without causing undue stress.

Title: Manufacture of resinous of condensation products
IPC: C08G12/42
Filed: 1940-06-28
Abstract: .543,360. Resinous condensation products. SOC. OF CHEMICAL INDUSTRY IN BASLE. June 28, 1940, Nos. 10995 and 10996. Convention dates, July 1, 1939 and Nov. 10, 1939. [Class 2 (iii)] Resinous condensation products are prepared from aminotriazines, compounds containing alcohol groups, and aldehydes or compounds which yield aldehydes, by re-acting them simultaneously or in any desired order of succession at a temperature below 50‹ C. in the presence of a relatively large proportion of an acid catalyst, i.e. about “ mol. or more of acid catalyst to 1 mol. of the aminotriazine. Under these conditions, etherification proceeds to a considerable degree while polymerization proceeds only to a small extent, and the products can then be subjected to an after-condensation, e.g. at a higher temperature and in the presence of a smaller proportion of acid, to effect further polymerization and, if desired, also the replacment of an alcohol of low molecular weight by a higher alcohol. A diluent may be present, and this may consist of an excess of the alcohol used, or may be an indifferent hydrocarbon, whereby, after neutralization, the separation of the water present and of the salt formed is facilitated. The neutralization may be interrupted when the acid has been rendered ineffective to such a degree that the residual acid just suffices for the after-condensation. Specified aminotriazines. are: melamine, melam, melem, mellon, ammeline, ammelide, foimoguanamine, trimethylmelamine, 2-chloro-4:6- diamino-1:3:5-triazine, 2-(para-oxyphenyl)-4:6- diamono-1:3:5-triazine, 2-phenyl-4-amino-6- oxy-1:3:5-triazine, 2:4:6-trimethylamino- 1:3:5-triazine, 2:4:6-triphenylamino-1:3:5- triazine, and their iso-derivatives. Specified aldehydes are : formaldehyde, acetaldehyde, benzaldehyde and furfurol. Specified compounds containing alcohol groups are : methyl, ethyl, propyl, isopropyl, butyl, lauryl, cetyl, stearyl, allyl, vinyl, benzyl, furfuryl and wool fatty alcohols, cyclohexanol, terpineol, borneol, abietinol, mono- and di-glycerides of saturated or unsaturated higher fatty acids, resin acids or aromatic caboxylic acids, glycol mono-ethyl ether, and condensation products, still containing alcohol groups, which are derived from poly-alcohols and poly-basic carboxylic acids, and 'derivatives thereof modified by monobasic acids. Specified diluents are benzene, toluene, xylene, solvent naphtha, lacquer benzine and dipentene. Examples are given. The resinous condensation products may be admixed with natural or artificial resins, oils, softening agents, nitrocellulose and acetyl cellulose. They can be used as coating, binding, and impregnating agents, for treating textile materials, and in the production of printing colours. Specifications 486,519 and 486,577 are referred to.

Abstract: 939,522. Spinning processes; tensioning yarn; bobbins. COURTAULDS Ltd. March 26, 1962 [March 27, 1961], No. 11027/61. Classes 120 (2) and 120 (3). Shrinkable yarn, e.g. doubled yarns spun from a blend of stabilized and high shrinkage polyacrylonitrile staple fibres and in which bulk is to be developed by a liquid treatment, is wound into a package having an open structure on a removable, e.g. collapsible or tapered, former under a yarn tension which progressively decreases, e.g. continuously but not necessarily uniformly, during the winding and may finally approach zero. As shown, yarn 7 drawn from a supply cone 17 is wound by a driving roller 5 and traversing guide (not shown) into a package 4 on a former 1. As the diameter of package 4 increases, the resultant pivotal movement of supporting arms 2, in the direction of arrow A, causes a rider 9 to move a link 10 and shift a rod 11, in the direction of arrow B, so that a pin 12 moves one half 13 of a tensioning gate 13, 14, and thereby adjusts the relative disposition of hooks 15 and 16 to reduce the restraint on the yarn passing therebetween.

Paper and like tubes. - Paper &c. tubes are formed by feeding a web A of paper &c. from a roll 7 to one of a series of mandrels 16 which are rotatably mounted on an intermittently rotated holder 17. Each of the mandrels are provided with holes 22, Fig. 3, which are placed in approximately the position in which the leading end of the web makes contact with the mandrel and means are provided for creating a vacuum in the mandrel so that the web will be held in contact therewith, while they are rotated continuously by a gear wheel 19 which is driven by a, pinion 20 on the power shaft 21 and is formed with internal teeth engaging teeth 18 thereon. The holder 17 is rotated by a roller 26 carried on a continuously rotating disc 27, also driven from the power shaft, which engages in turn each of a series of slots 25 therein, and it is prevented from shifting during the performance of the various operations by a locking arm 31, actuated by a cam 30 on the disc 27, having a tooth 32 engaging one of a series of notches 33 thereon. In operation, tha web is fed through pasting apparatus, Fig. 1, comprising a pasting roller 8 revolving in contact with a feed roller 9 which dips into paste contained in a reservoir 10, a squeegee roller 11 adjustable by a screw preferably being provided for regulating the supply of paste, and then to the mandrel shown in position B, Fig. 2, where it is wound. Just' before the completion of the winding operation the holder 17 is rotated partially so that the mandrel moves to the position C, carrying the web forward and causing it to contact with the mandrel which takes its place. At about the same time the web is severed, at a point that will leave sufficient to complete the tube on the first mandrel, by a breaker arm 23 which is so formed as to hold the severed end of the web in contact with the next mandrel until it is gripped thereby. The mandrel thereafter moves successively to positions D, E where the formed tube may be subjected to pressure rolls, and finally to position F where the tube is removed from the mandrel.

Abstract: 484,753. Closures for bottles &c. BUGH, J. D. April 21, 1937, No. 11405. [Class 125 (iii)] A closure and seal for a bottle or jar comprises a cap adapted to be superimposed over the screw cover to prevent access to the latter and capable of being depressed relatively to the cover so that it can be removed to give access to the cover and by its depression giving an indication on the bottle or jar that the latter has been opened. As shown, the cap 8 is secured over the screw cover 7 by its flange 9 which is turned inwards between the cover and the bead 6 of the bottle &c. so as to secure the cover on the latter with the top of the cap spaced from the cover. To remove the cap to give access to the cover, the cap has to be depressed so that the flanges 9 are bent upwards and, in so doing, a marker pin 11, secured to the inside of the rim of the cover, nicks the edge of the bead 6 and leaves a permanent indication that the bottle &c. has been opened or tampered with. In a modification, a soft wire is moulded in the bead and exposed for part of its length which is severed by the pin 11 when the cap is depressed.
