Title: Improvements in or relating to wrapping machines
IPC: B65B11/32
Filed: 1950-04-03
Abstract: 684,252. Labelling. machines. FORGROVE MACHINERY CO., Ltd., and RUSSELL, A. April 2, 1951,. [April 3, 1950] No. 8269/50. Class 73. [Also in Groups XVI, XVII and XXX] In a wrapping-machine (see Group XVII) in which end-seals are applied to packages as they are moved by a step-by-step conveyer (see Group XXX) along a discharge platform 75 between side plates 324, webs of end-seal material 375, consisting of interconnected end-seals 432 coated with thermoplastic adhesive, Fig. 20A, are fed from reels 37, Fig. 20, at each side of the platform 75 by adjustably-mounted intermittently-driven peg rollers 377, the pegs 378 of which engage between adjacent seals. Each roller is rotated by a pawl and ratchet operated through linkage by a push rod 383 which is actuated through a spring 381 and bell-crank 382 by a cam 342. The drive to the rollers is rendered inoperative if a trip member 440 projecting through the platform is not depressed by a package prior to its movement to station H. The leading end of each web is guided by a member 380 into a V groove 433 in the bottom edge of an aperture 376 in each side plate, and end-seals are severed from the webs and pressed against the end fold s of the wrapper by adj ustably-mounted knives 402 and heated pressers 403 carried bv rods 404 which are reciprocated through linkage by an arm coupled to a bell-crank 351. This unites the central portions of the end-seals to the wrapper and causes adhesion of the overlapping end flaps over the central zones of the ends of the package. If the wrapper is not made of heat-sealable material, adhesive is applied by a roller 369 to the undersurafce of the end flap 326 of the wrapper before it is folded. As the package moves from station H, fixed tongues 418 on the plates 324 flatten the end-seals. At station I the sealing of the ends of the package is completed by heated presser members carried by rods 406 which are coupled by cross-heads 407, 408 to the rods 404. These presser members are each formed of two portions arranged to engage the end of the package above and below the zones at which a partial seal was effected at station H. The heat-sealing faces of the presser members are in the form of a flexible grid which acts as an electrical resistor and is caused to assume a convex shape by an insulated spring-loaded plunger. The current to the heaters is controlled by a microswitch operated by the trip member 440. The completed packages are discharged through a shoot at the end of the platform. Specifications 567,196, [Group XVI], 622,593, [Group XVII] and 684,259 are referred to.

Patent GB-453854-A (GB)
Title: Process for the manufacture of polymerisation products from olefines
IPC: C08F10/00
Filed: 1935-03-18
Abstract: The polymerization of olefines (including butadiene) is effected above about 50 DEG  C. by the action of boron fluoride compounds containing at least one atom of hydrogen capable of removal by dissociation.  Suitable catalysts are compounds of boron fluoride with water, alcohols, and acids such as the dihydrate, dialcoholate, and the compound of boron fluoride with acetic acid.  In some cases at low temperatures a different reaction may occur; thus boron dihydrate converts propylene to di-isopropyl ether at ordinary temperature.  In examples: (1) propylene is treated with boron fluoride diacetate at 100--120 DEG  C. and 15--20 atmospheres, a liquid product being obtained probably containing pentadecylenes and octodecylenes; (2) propylene is treated with boron fluoride dihydrate at 80 DEG  C. and 15--20 atmospheres; (3) a  and b  butylenes are treated with boron fluoride dihydrate at 60 DEG  C.; (4) ethylene is treated with boron fluoride dihydrate at 110 DEG  C. and 30 atmospheres; (5) isobutylene is treated with boron fluoride dihydrate at 100 DEG  C. and 5--10 atmospheres; (6) butadiene is treated with boron fluoride dihydrate at 60 DEG  C. and 5 atmospheres yielding a viscous oil and an elastic to brittle resin.  The Provisional Specification describes the use of the compound of boron fluoride with phosphoric acid described in Specification 451,359, [Group III], for the polymerization of propylene and ethylene.

Inventor: GIBSON THOMAS
IPC: C23C10/42
Filed: 1951-04-16
Abstract: Ferrous articles are chromized by packing in a mixture, preferably granular, of ferro-chromium and an inert, porous, refractory material impregnated with anhydrous chromous chloride in an airtight retort, and heating whilst passing therethrough gaseous hydrogen chloride, at least at the commencement of the chromizing, and hydrogen. Impregnation of the refractory material may be effected by passing a stream of hydrogen chloride for 2-4 hours through the mixture at 1000-1100 DEG  C. and then cooling under reducing conditions; during the heating up to reaction temperature a hydrogen atmosphere should be maintained.  The refractory may be sillimanite or calcined bauxite.  Air may be flushed from the retort by passing hydrogen until the temperature reaches 450 DEG  C. when the supply is reduced to just sufficient to maintain reducing conditions; hydrogen chloride is passed through the retort whilst the temperature rises from 1000 DEG  to 1050 DEG  C. and thereafter cut off or greatly reduced; chromizing continues at 1050 DEG  to 1150 DEG  C. for 8-2 hours; cooling takes place in the presence of hydrogen, but without hydrogen flow through the retort.  The ferrous articles may be formed of alloys containing C up to 0.5 per cent; titanium is also preferably present, the Ti:C ration being 4:1 to 5:1, alloys containing C 0.1 per cent and Ti O.5 per cent, and C 0.2 per cent and Ti 1.0 per cent being referred to; Mn up to 3.5 per cent, Mo up to 1.0 per cent, Ni up to 5 per cent and V up to 0.5 per cent may also be present.

Title: Improvements in or relating to endless flexible belt conveyors
IPC: B65G39/06
Filed: 1949-04-01
Abstract: 669,757. Endless-belt conveyers. ARMSTRONG, B. M. March 16, 1950. [April 1, 1949] No. 8853/49. Class 78 (i). The peripheral wall of an idler roller of hollow construction is formed of resilient material and defines the outer boundary of an annular air space within the roller, the thickness of the wall being such as to maintain the annular air space in being without initial inflation under pressure, the air space being sealed to produce a cushion providing in combination with the inherent resilient support afforded by said wall, means for absorbing the impact of gravitationally delivered loads whereby the risk of damage to the belt by such loads is reduced. As shown, the wall 4 of rubber is supported on a bush 6 which is screw threaded internally for engagement with a correspondingly threaded metal cylinder 8 so as to form an annular air space 9 sealed off from the atmosphere. A metal bush 10<SP>1</SP> closes each end of the cylinder 8, being frictionally secured as at 11, and the inner face of the bush is hollowed out to provide a seating for the outer race 12 of a ball bearing, the inner race of which is mounted upon a shouldered portion of the shaft 10 extending through the interior of the roller. A passage 18 in the shaft closed by a grease nipple 19 enables the bearing to be replenished with lubricant. A ring 16 prevents lubricant escaping to the interior of the cylinder and a felt or like washer 17 prevents it escaping along the outer part of the shaft. Circumferentially spaced holes 20 in the wall 4 increase its flexibility particularly when the rollers are arranged in trough formation, they are formed with a helical tread as described in Specification 669,758.
