Title: Improvements in and relating to the preparation of polyolefin foams
IPC: C08J9/00
Filed: 1966-01-05
Abstract: The invention comprises a foamed polyolefin polymer containing a low molecular weight hydrocarbon oil as defined below present in amounts from 5-100% by weight based on the polyolefin and in a separate disperse phase in said foamed polymer.  The polyolefin may be a polymer of a mono-olefin having 2 to 3 carbon atoms which is optionally crosslinked with ethylene - propylene - dicyclopentadiene terpolymer, styrene-butadiene copolymer, styrene-divinylbenzene copolymer or styrenemaleic anhydride adduct.  Suitable polyolefine polymers are low and high density polyethylene, polypropylene, chlorinated polyolefins as well as copolymers of ethylene with propylene or a -mono-olefines containing 4 to 10 carbon atoms e.g. butene-1 or octene-1.  The low molecular weight hydrocarbon oil is a hydrocarbon resin oil (M.W. 1,000 to 10,000), microcrystalline wax, montan wax, "Gilsonite" ("Gilsonite" is a Registered Trade Mark), coal tar pitch, petroleum asphalt, polyisobutene oil, pine tar, chlorinated polybutene oil, an ethylene oxide polymer or a coumarone indene resin.  The desired foamed product, which may have at least one unfoamed skin, is obtained by adding to an extruder a potentially foamable composition comprising a polyolefin and a low molecular weight hydrocarbon oil, subjecting the mixture to heat in the extruder, extruding the composition, foaming the composition and, if desired, quench chilling at least one surface of the extrudate.  The potentially foamable composition comprises, in addition to the above-mentioned components, a specified blowing agent, preferably a volatile liquid with a boiling point in the range 10-100 DEG  C., absorbed on a suitable solid absorbent; a known nucleating agent, if desired; known fireproofing agents or conventional organic or inorganic solid fillers which may be treated to remove chemisorbed water; and compounding agents such as halogenated oils.  The composition may contain a free radical engendering material or be treated with high energy ionizing radiation.  Foamable compositions comprising polypropylene and microcrystalline wax or high density polyethylene and hydrocarbon resin oil or coal tar pitch are described.

Abstract: 823,052. Electric battery lamps. WITTE, W. Jan. 6, 1956 [Oct. 15, 1955], No. 526/56. Class 39(2) [Also in Groups XIV and XXXV] A pocket lamp or other form of portable electric lamp, comprising a casing which houses one or more accumulators 11 and a rectifier 23 whereby the accumulator may be charged through plug pins 18b, 18c from an A.C. mains supply, is provided with an internal circuit arrangement wherein a condenser 43 and a resistance 51 are connected in series with the accumulator and the rectifier 23. The resistance 51 is provided with tappings whereby the condenser can be by-passed by a lead (indicated by broken lines in Fig. 1) connected to a plug or pin 18a to enable the accumulator to be charged from the low voltage D.C. power supply of a motor vehicle. In order to protect the rectifier 23 from the harmful excess voltage when the pins are plugged into the mains socket an auxiliary rectifier 52 is connected across the points 53, 54, within the lamp housing, in series with the resistance 51. To protect a user from an electric shock on touching the pins 18b, 18c when withdrawing them from a charging socket, an internal resistance 50 is connected across them. A voltage-sensitive semi-conductor such as a resistor may be used in place of the rectifier 52.

Title: Process for the production of fibrillated polyolefin products
IPC: D01D5/42
Filed: 1969-01-03
Abstract: 1,246,052. Producing fibrillated polyolefine products. J. P. BEMBERG A.G. 3 Jan., 1969 [3 Jan., 1968], No. 530/69. Heading B5B. In the production of fibrillated polyolefin products by melt-extruding polyolefinic material to form film or film strips, longitudinally orienting the film or the strips at a high draw ratio and fibrillating the oriented product by mechanical treatment, the polyolefinic material comprises polypropylene as the main constituent, the polypropylene comprising 5 to 30% by weight of atactic components, and the minor constituent is low-pressure polyethylene present in a proportion of up to 30% by weight. The polyethylene renders it possible to fibrillate satisfactorily polypropylene films or film strips &c. consisting of polypropylene containing significant proportions of atactic components, which films &c. can otherwise not be fibrillated to obtain usable products. The fibrillation of the film strips &c. may be increased by incorporating in the polymer mixture small proportions of blowing agents which generate gases when the film strip is heated or contacted with water. In the example, 100 parts by weight of polypropylene containing about 20% by weight of atactic polypropylene is mixed with 20% by weight of low-pressure polyethylene and the mixture is melt extruded at 280‹ C, to form a film which is solidified by cooling, and slit longitudinally into strips. The strips are drawn at a draw ratio of 9À5 and fibrillated by twisting to form fibrillated fibres.

The return pass 12, which has an outlet 14 in the rear wall of the boiler, is arranged to one side of the space covered by the vertical projection of the drums 1, 2. A row of downcomer tubes 15 are installed behind the wall tubes 6, and access openings are provided in the front and rear walls of the boiler.

Abstract: 512,834. Mortising wood. HURE, L. H. F. Jan. 7, 1938, No. 580. Convention date, Jan. 7, 1937. [Class 145 (i)] [Also in Group XXII] A drilling, milling, mortising &c. machine has a universal spindle head including two rotatable tables whereof one provides for angular adjustment of the spindle in a vertical plane and the other for angular adjustment in a plane at 45 degrees thereto, the head also being capable of horizontal adjustment relatively to the work. The spindle sleeve 4 is carried by a head 5 angularly adjustable about graduated flanges 6, 9 on a head 8 which is angularly adjustable about a vertical graduated flange 10 on a ram 2. The ram may be fed horizontally on a carriage 11 either manually or from an electric motor 16 on the carriage through a change speed gear 17, and the carriage is vertically displaceable on a pillar 12 which may be fed horizontally on the base 13 either manually or from a motor in the base and a change speed gear 18. The work may be supported directly on a part 15 of the base 13 or on a table 14 vertically adjustable on the base, or may be mounted on a table carried by the part 15 and having a longitudinal adjustment. The graduated scales for the spindle adjustment are each marked in degrees from 0 degrees to 360 degrees to facilitate setting the spindle in angular positions. The tool spindle 4 is driven from an electric motor 1 on the ram 2 through a change speed gear 3 in which a worm wheel 19 rotated by the motor is connected by bevel gears 21 to a shaft 22. Pinions 23, 24 are fast on the shaft and pinions 25, 26 and 27, 28 are splined thereto so that a second shaft 29 may be driven at six different speeds by operation of the yokes 34 ... 36. Incorrect operation of the yokes is prevented by pointed sliding pins 37... 39 engaging depressions in the spindles thereof. The six speeds of the shaft 29 are converted into twelve speeds of a third shaft 30 by sliding the shaft to cause a gear 30a secured thereto to engage a gear 32 or a clutch 30b thereon to engage a gear 31 driven from the shaft 29.

Abstract: 487,507. Stapling fibres. COURTAULDS, Ltd., COLESHILL, F. R., and McKEOWN, J. H. Jan. 8, 1937, No. 611. [Class 120 (iii)] In the production of staple fibre by a process in which a continuous thread or bundle of threads is stretched by passing in succession round two or more peripheral surfaces each rotating with a peripheral speed greater than the previous one and is thereafter cut, the thread or bundle before arrival at the cutter is passed round another peripheral surface rotating with a speed so much less than that of the last of the stretching surfaces as to compensate approximately for the contraction which takes place. The thread or bundle may be passed round a third roller rotating at a slower peripheral speed and it may form part of the second roller of reduced diameter. In an alternative the thread may be stretched by passing round a conical roller from the narrow to the broader end and may be allowed to contract on a second conical roller by passing round it from the base towards the narrower end. The surfaces may be grooved, corrugated or fluted. Specifications 289,028, [Class 120 (iii)], and 467,500, [Group IV], are referred to.
