Title: Polymer compositions derived from unsaturated nitriles and elastomers
IPC: C08G65/00
Filed: 1972-08-18
Abstract: 1354454 Unsaturated nitrile copolymers; hydroperoxide-modified polyethers SOLVAY & CIE 18 Aug 1972 [19 Aug 1971 14 April 1972] 38655/72 Headings C3G C3P and C3R A composition is obtained by polymerization of 97-70 parts by weight of (a) a mixture of 50 to 99% by weight of an olefinically unsaturated nitrile and 1 to 50% by weight of an olefinically unsaturated comonomer in the presence of 3 to 30 parts by weight of (b) an elastomer based on epichlorohydrin. The nitrile may be acrylonitrile. The comonomer may be an ester of formula CH 2  = CR 1 -CO 2 R 2  where R 1  is hydrogen, halogen or a branched or unbranched C 1 -C 4  alkyl radical and R 2  is a C 1 -C 12  hydrocarbon radical or of formula CH 2  = CH-O 2 CR 2  or a C 2 -C 8  α-olefin. The elastomer may be polyepichlorohydrin, an epichlorohydrin-alkene oxide copolymer or an epichlorohydrin-unsaturated epoxide copolymer and may contain hydroperoxide groups and act as the initiator. The polymerization may be effected in the presence of a mercaptan and/or a polyvinyl alcohol, methyl cellulose or hydroxyethyl cellulose as dispersant. Where (b) is a copolymer (a) may be grafted on to it during the polymerization. In Examples 1-22 acrylonitrile is polymerized in the presence of polyvinyl alcohol and dodecyl mercaptan using azobisisobutyronitrile or benzoyl or dicumyl peroxide as catalyst and in 1-7 the comonomer is methyl acrylate and (b) is a copolymer of epichlorohydrin and allylglycidyl ether or a terpolymer of these with ethylene oxide or propylene oxide and in 8-22 the comonomer is methyl, ethyl butyl or 2 ethyl hexyl acrylate; isobutylene, vinyl acetate or methyl methacrylate and (b) is polyepichlorohydrin or a copolymer of epichlorohydrin and ethylene oxide which in Example 17 had been reacted with acetyl cyclohexane sulphonyl peroxide to form hydroperoxide groups therein.

Title: Improvements in or relating to buffers for railway and like vehicles
IPC: B61G11/08
Filed: 1930-12-29
Abstract: 366,670. Buffers for railway &c. vehicles. MITCHELL, J., 69, Kenilworth Court, Putney, and COSSEY, J. C. G., Calbourne, The Vale, Golders Green, both in London. Dec. 29, 1930, No. 39054. [Class 103 (v).] In a railway &c. vehicle buffer of the kind in which a buffer head g<1> and sleeve g slide within a cylindrical casing a containing in addition to the usual springs e further springs c at the rear for absorbing the final shocks, and in which a spindle f associated with the buffer head passes through the headstock h and is fitted with a recoil spring p, the spindle f is flexibly connected to the buffer head in order to lessen its liability to fracture. In the construction shown in Fig. 1, the head f<1> of the spindle f is received within a pocket g<2> formed at the rear of the buffer head, while the springs c, e are separated by a washer k which normally contacts with a shoulder formed by enlarging the portion a<1> of the casing that contains the spring c. In buffing, the springs c, e are compressed in series until the inner end of the sleeve g, which may be either integral with or riveted to the buffer head g<1>, strikes the washer k, after which only the spring c is subject to the further compression. For converting existing buffers with plain cylindrical sleeves the rear portion a<1> of the casing may be made separate from and riveted to the front portion. In a modification, Fig. 6, a shouldered sleeve j<1> is arranged in the casing to bear against the rear of the spring e, so that initially only the spring is compressed and subsequently both springs c, e in parallel. In another modification, Fig. 7, a washer j at the rear of the spring c is associated with a small sleeve n<1> projecting through the headstock h whereby the recoil shock is absorbed by the spring c.

Patent GB-1477326-A (GB)
Title: Method and apparatus for classifying paper fibres
IPC: B07B13/00
Filed: 1974-09-09
Abstract: 1477326 Classifying fibres BELOIT CORP 9 Sept 1974 [17 Sept 1973] 39280/74 Heading B2H Paper pulp fibres are classified according to length by directing a stream of fluid containing a mixture of the fibres in suspension against an edge of a separation member so that long fibres double over onto a portion of the edge of the member; moving the said edge portion of the member out of the stream; and removing the long fibres from the said edge portion after it has been moved out of the stream. In Fig. 1, a stream 11 of gaseous or liquid fluid containing a paper pulp fibre mixture is impelled by a pump 12 through a conduit 10 which directs the stream as a jet against the edge of a rotating disc 13. The long fibres are retained by the edge of the disc and are removed therefrom by a metal, rubber or plastics blade 16 so that they fall into a container 18. The unretained short fibres continue on past the disc in the stream as shown at 20. Instead of the blade 16, a rotating disc moving transverse to the direction of movement of the disc edge may be employed. Alternatively, the fibres may be removed from the edge by a jet of air which may be directed radially relative to the disc and which may serve as a carrier stream for conveying away the long fibres. A plurality of coaxial discs adjustably spaced from one another may be employed with a relatively broad fluid jet and the stream may be recirculated to further collect any long fibres which may have flowed past the discs. The discs may also be positioned in series with their widths narrowing in a downstream direction so that the first discs catch longer fibres than the succeeding discs. In Figs. 2 and 3, a wire or, as shown, a steel band 28 travels across a fibre suspension stream 26 flowing through a conduit 25. The long fibres collected on the leading edge 28b of the steel band are carried by the travelling band, e.g. via an adjustable opening 33, into a separation chamber 32 in which they are combed off the band by blades 35, 36 and carried through a discharge conduit 39 by means of a fluid stream directed into the chamber through a conduit 37 from a fan or pump 38. Multiple bands may be employed and additional multiuple stages may be provided downstream to collect additional fibres.

Title: Improvements relating to the application of heat to glass feeder forehearths
IPC: C03B7/06
Filed: 1965-09-15
Abstract: A glass feeder forehearth heated by gas burners is characterized by a flue exhaust system in which stack pull is eliminated in that all the air required for combustion is supplied by the burners, the gas and air being fed to each burner separately, gas and air flow control means being provided to maintain the gas to <PICT:1065748/C1/1> <PICT:1065748/C1/2> air ratio substantially constant with changes in flow rate.  A plurality of burners 25 (Figs. 3 and 13) are situated in the forehearth sidewalls. Gas is supplied to the burner nozzle 29 from a main 27 by pipe 28, the combustion air being supplied to an air nozzle 32, surrounding nozzle 29, from a plenum chamber 31 connected to a pressurized air duct 30.  The combusted gases leave outlet port 26 and enter a combustion space 20 above the glass surface 19.  The gases exhaust through a port 34 above the burner port 26, thence a vertical flue 33 which is vented to atmosphere at the bottom by a duct 35.  Since all combustion air is supplied at a positive pressure direct to the burner the gases will exhaust without the need for a stack pull.  Various different embodiments are described wherein the position of the ducts 34 and 35 and flue 33 are varied.  In an alternative form (Figs. 8 to 10, not shown) the waste gases exhaust through a central port 37 at the top of the combustion space, enter a common duct 38, 39 and then exhaust through a flue comprising a downward channel 40 and an upward compensating channel 41 vented to atmosphere at its base.

Abstract: 1385634 Electroluminescence STANDARD TELEPHONES & CABLES Ltd 21 Aug 1973 39439/73 Heading C4S [Also in Division H1] A heterostructure GaAPAs semi-conductor laser has one limit of an optical confinement region including a P-N junction clearly defined at the boundary between layers 11 and 12 by an abrupt increase in aluminium concentration in layer 12, while the other limit of the confinement region is less precisely established by arranging the aluminium concentration in layer 11 to increase without discontinuity from its boundary with layer 12 to its boundary with a substrate 10. The layers 10, 11 and 12 respectively comprise GaAs, Ga (1-x) Al x As and where y>x, y is constant and x decreases progressively in the direction from the substrate 10 to layer 12. A further layer 13 of GaAs on layer 12 facilitates the provision of a metallized contact. In Fig. 1 the substrate 10 and layer 11 are N-type and the layers 12, 13 are P-type, the zinc doping of layer 12 being diffused into layer 11 to produce a P-N junction 11a. The reduction in concentration of aluminium through layer 11 is produced by progressively deleting the aluminium content in a melt during the growth process, concentration values being given. The resulting variation of refractive index n through the layers which delineates the confinement region is shown in Fig. 2. In alternative germanium doped structures, Figs. 3 and 5 (not shown), the substrate may be N- type or P-type with a corresponding doping relationship through the layers, the P-N function being defined by the boundary between layers 11 and 12.

Abstract: 1,158,568. Fascimile apparatus. RANK XEROX Ltd. 12 Sept., 1966 [20 Sept., 1965], No. 40609/66. Heading H4F. The Specification describes a facsimile apparatus having means for scanning a document, &c. and transmitting the resultant signals and means for producing a recording from received signals, wherein both said means share a common scanning member 11 in the form of a rotating many sided pyramidal mirror assembly - see Fig. 1, the scanned light from the document 89 being reflected off of one side of the assembly and the light from a source 120, intensity modulated in accordance with the received signals being reflected off of the other side of the assembly on to the recording assembly. The document 89, on a drum 90 rotated by motor 91 is illuminated along an axial line by the light from a source 92. The light reflected from the document is reflected by mirror 94 on to scanning assembly 11. As this rotates, under the action of motor 104, the light reflected upwards by the assembly scans along the illuminated line of the document. The document is thus scanned over its entire surface, successive mirrors on assembly 11 scanning successive lines. The scanned line is fed to a photo-multiplier 118 and transmitter 119, via lenses 105, 113, mirror 114 and lens 117. The output of the transmitter may be fed to modulate light source 120, as well as to remote reproducing means. The light from source is focused by lens 125 and reflected by mirror 126 on to scanning assembly 11. The scanning beam of light thus reflected from the mirrors of assembly 11 is reflected by mirror 129 on to the drum 131 of a zerographic reproducing assembly, Fig. 3 (not shown). An externally received signal may be reproduced using receiver 143. Figs. 4, 5 and 6 show optical arrangements whereby, strip recorded material, books and film may be scanned, whilst Fig. 7 shows how an optical arrangement for scanning strip recorded material can be converted into one for scanning film.
