Title: Improvements in the production of wrapped packages
Inventor: JOHNSON REGINALD FRANK
IPC: B65B9/06
Filed: 1955-11-24
Abstract: 795,397. Wrapping-machines. ROSE BROS. (GAINSBOROUGH), Ltd. Nov. 2, 1956 [Nov. 24, 1955], No. 33654/55. Class 94(1). Articles 11 are fed in spaced succession by pushers 13 on a chain 14 and deposited on a travelling web 16 of heatsealable wrapping material which passes over a platform 17 and is folded by ploughs 18 to form a tube enclosing the articles. The edges 19 of the web pass through a central guide 21 into the grip of heated sealing rollres which unite them to form an upstanding seam which is subsequently folded flat by a plough 20. The tube then passes between rotatable sealing members 22 having opposed pairs of heated members 23 serving to collapse and seal the tube transversely between successive articles. Knives 24 between the members 23 are arranged to sever the tube across the sealed portions to form a succession of packages 26. The members 23 also serve to feed the web forward, their action being assisted by a pair of driven side belts 27 extending alongside the platform 17 with which they form a trough in which the tubefolding operation is initiated. A suction conduit 28 of flat cross-section extends close to the upper surfaces of the article a substantial distance into the completed tube, the conduit passing out of the partially-formed tube at 29 and being connected to a source of suction. The web is thus folded about the articles and the conduit and the latter serves to withdraw air continuously from the tube so that the space between successive articles is maintained under sub-atmospheric pressure while the tube is collapsed and sealed between those articles.

Title: Process for the dyeing of wool with complex heavy metal compounds of dyestuffs
IPC: D06P3/64
Filed: 1954-11-22
Abstract: In the dyeing of wool with complex heavy-metal compounds, e.g complex chromium or cobalt compounds, of monoazo or azomethine dyestuffs which contain two dyestuff molecules bound to one heavymetal atom and no acid water-solubilizing groups other than any carboxyl groups taking part in the complex formation, the wool is pretreated with a heated mineralacid liquor until the pH of the liquor is constant between 4 and 6 and then, at a liquor temperature of over 80 DEG C., the dyestuff is added and dyeing is performed in the presence of a nitrogen-free capillary active polyglycol ether while heating and circulating the liquor or moving the goods well until the bath is exhausted.  Specified mineral acids are sulphuric and phosphoric acids and, in the case of carbonized wool, an aqueous bath is sufficient for the pretreatment.  Specified polyglycol ethers are the ethylene oxide addition products of fatty alcohols, e.g. dodecyl, hexadecyl, octadecyl and oleyl alcohols or mixtures thereof, or of alkylated phenols, e.g. 4-isooctyl, 2:4-di-tert.-butyl- or -di-tert.-amyl-, 4-dodecyl - and 3 - or 4 - nonyl - phenol.  Examples are given. Specification 750,648 is referred to.

Title: Improvements in or relating to steam power plants
IPC: F01K7/38
Filed: 1932-11-29
Abstract: 398,061. Steam-power plant. SULZER FR’RES SOC. ANON., Winterthur, Switzerland. Nov. 29, 1932, No. 33747. Convention date, Aug. 20. [Classes 110 (iii) and 122 (iii).] A steam generator 4 of small liquid capacity supplies steam to a steam-engine 6 from which steam is bled for a feedwater heater 1. Two regulating devices are provided..The quantity of steam fed to the heater 1 is increased or decreased according as the engine load is decreased or increased respectively. This control is effected by a governor 12 regulating a valve 13 in the bleed connection. The output of the generator 4 is regulated in accordance with the heat content of the feedwater heater. When the heat content increases or decreases, the generator output is decreased or increased. When the engine load is reduced or increased, the supply of heat to generator 4 is likewise reduced or increased. The engine has high- and low-pressure stages H, N and drives a generator 7. The feedwater supply device 14 may contain an operative medium which expands or contracts and thus controls the fuel through a valve 15. In a modification, the high and low-pressure stages are separate, a low-pressure generator supplies steam to the low-pressure stage. The high-pressure stage communicates with the low-pressure stage through a pipe connected to the feed-water heater. A governor driven by the low-pressure stage controls the bleed-steam supply. The valve 13 may be regulated in accordance with the engine-shaft torque, or by means of an electric-power measuring device. The quantity of steam bled may be regulated by adjusting the quantity of steam fed to a low-pressure stage of the engine. The fuel supply and/or feed-water supply to the steam generator may be controlled in accordance with temperature variations at several different points in the feed-water heater. The quantity of liquid medium fed to the generator may be controlled by the temperature and pressure of the steam generated. When the pressure rises above or falls below a predetermined value, the liquid fed will be reduced or increased respectively. The high and low-pressure stages may be coupled mechanically or electrically. Steam may be supplied to the low-pressure stage or stages from a separate low-pressure generator.

Abstract: 1,006,575. Burring apparatus. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. Sept. 4,1962 [Sept. 7,1961; Jan. 17,1962], No. 33915/62. Burrs are removed from fibres by being set above the general level of fibres on a moving surface and knocked in a direction generally transverse to that of the surface. Preferably, the burrs are also knocked in a direction having a component opposite to that of motion of the surface. One embodiment described utilises a burr beater 10 in the form of a rotary cylinder formed with helical blades. This cylinder operates in conjunction with a working roller 2 formed in its periphery with a series of undercut circumferential grooves. Fibres in partially aligned condition are drawn into the grooves by the tension imposed by drafting rollers and burrs are left on the surface of the working roller to be beaten off by the helical blades. Instead of the helically-bladed roller there may be provided a band-saw-like blade with teeth that are backwardly raked and with leading edges bevelled, the blade being caused to move transversely. Specification 886,103 is referred to.
