Title: Pneumatic tire
IPC: B60C15/06
Filed: 1956-06-07
Abstract: 834,425. Tubeless tyres. DAYTON RUBBER CO. June 7, 1956 [June 13, 1955], No. 17571/56. Class 144 (2). In a tubeless tyre, which may have circumferential sealing ribs 28 provided on the surfaces of its beads which engage the bead-retaining flanges 29 of the wheel rim 30, at least parts of the rim contact area of the beads are composed of a rubbery material having embedded therein a plurality of individual discrete fibres which extend unidirectionally substantially parallel to the line of contact in transverse section between the beads and the rim surfaces. The fibres tend to prevent flow of the rubber during moulding and ensure an adequate thickness of bead-covering rubber at the base of the grooves between the sealing ribs 28. As shown, the fibre reinforced material is built into the tyre in the form of a chafer strip extending from the axially inner surface of the bead 21, where it overlaps the air-impervious butyl rubber lining 24, to a point radially outwardly of the edge of the rim flange 29. The strip is cut from a calendered sheet so that the fibres, which have a length ranging from ¢ to 2 inches, aligned by the calendering extend parallel with the bead surfaces in transverse section. Suitable fibres include cotton wool, glass, cellulose acetate, polyacrylonitrile polyamide and polyester fibres, and suitable rubbery materials comprise natural rubber and synthetic rubbers such as butadieneacrylic nitrile and butadiene-styrene copolymers, and polychloroprene rubbers. The fibres may be added in the proportion of 10 to 100 parts by weight per 100 parts by weight of rubbery base material which may be compounded with suitable fillers.

Title: Method of and means for Producing a Two or more Channel Sound Signal of a Stereophonic Type
Inventor: ARNOLD PAUL
IPC: H04S5/00
Filed: 1967-04-17
Abstract: 1,176,154. Stereophonic systems. DEUTSCHE POST RUNDFUNK-UND FERNSEHTECHNISCHES ZENTRALAMT, and DEUTSCHE SCHALLPLATTEN VEB. 17 April, 1967, No. 17608/67. Heading H4R. In apparatus for providing pseudo-stereophonic signals from monophonic sources, or increasing the stereophonic effect of stereophonic signals, the signal is fed through two channels of different delay times and the resulting signals treated as sum and difference stereophonic signals for conversion to left and right signals, and different frequency bands are separated from the signal and applied in varying proportions to the left and right signals. Reverberation may be added to the signals by use of an echo chamber. Fig. 1 shows an embodiment in which a signal from a source 1, e.g. a mono tape recorder, is amplified and fed to delay devices 31, 32, and 33, each having different delays. The output from delay 31 is applied via attenuator 41 as a " sum " signal to a conventional processor 51, to which is also applied the attenuated outputs of delays 32 and 33 as a difference signal, to produce left and right pseudo-stereo signals on lines X and Y. In addition, the signal from amplifier 2 is applied to a number of adjustable frequency filters 64 to 68, the outputs from which are fed via attenuators to directional controls 74 to 78 which distribute the signals controllably between the left and right lines X and Y. The resulting signals are applied to a directional mixer 13 to provide further directional control. The signals at the outputs of the filters 64 to 68 are also combined in mixer 10 and applied, via amplifier 80, attenuator 40, and delay 30, to an echo chamber 11 from which pseudo sum and difference signals are derived and applied to a processor 50 from which left and right channel signals are derived to be added to those from directional mixer 13. In an alternative reverberation channel. Fig. 2 (not shown), only one output is taken from the echo chamber and sum and difference signals are synthesized by providing two channels of different delay. Fig. 3 shows apparatus for processing stereo signals comprising stringed instruments on track S1, stereo left and right channels of the orchestra on channels 2 and 3 and a soloist on channel 4. In this arrangement the stringed instruments and the soloist signals are processed via a differential delay arrangement to provide pseudo sum and difference signals from which, via processors 13 and 143, left and right channel signals are derived to mix with the signals on channels S2 and S3.

Abstract: 652,851. Coloured mirrors. LIBBEYOWENS-FORD GLASS CO. July 12, 1945, No. 17855. Convention date, Feb. 16, 1943. Drawings to Specification. [Class 97 (i)] A coloured mirror comprises a partially transparent specular film which is of a thickness sufficient to produce colour by light ray interference and is applied to the front surface of a specularly reflecting body or to the front surface of an opaque or transparent body or to the front surface of a transparent body having a specularly reflecting film coated on the rear surface thereof or to the rear surface of a transparent body in which case a specularly reflecting coating is applied to the rear surface of the colour producing film. When the colour producing film is applied to the front surface of a transparent body having a specularly reflecting coating on the rear surface thereof, the refractive index of the film is greater than that of the transparent body. The colour producing film and specularly reflecting coating may be formed by chemical deposition as described and claimed in the Specification 624,846. or by thermal evaporation. The colour producing film may be deposited to give a uniform colour or an air current may be used to vary the film thickness and hence the colour. The body may be coloured, e.g. it may be a green glass and the colour producing film may be of a material, e.g. gold or copper, giving selective reflection of the incident light. Scratching of the mirrored surface may be prevented by the application of lacquer or shellac or by copperplating. Other materials from which the colour producing film may be made are lead sulphide, calcium fluoride, stibnite, molybdenite, pyrite, silicon and antimony. The specularly reflecting coating may be formed from materials, such as silver, aluminium, magnesium, platinum or chromium. Spectral reflection curves are shown. Specification 632,570 and U.S.A. Specification 1,662,654 also are referred to.

Abstract: 1430418 Bushing assembly WESTING- HOUSE ELECTRIC CORP 16 April 1973 [27 April 1972] 18236/73 Heading H2C An electrical bushing assembly for power transformers comprises a lead tube 10 coaxial within an upper casing member 20; and stressrelieving means 28 comprising a cap 30 having an opening 32 for the end 12 of the lead tube 10 to which it is secured by a nut 34, and a cup 40 having a flange 48 positioned between the cap 30 and the upper edge of the casing member 20. Coiled compression springs 38 enclosed between the cap 30 and the bottom 44 of the cup 40 maintain the lead tube 10 under tension and the casing member 20 under compression via a gasket 50, and relieve stresses due to differential expansion of the lead tube and casing member. A resilient 0-ring 54 compressed between the cap 30 and the flange 48 provides a fluid-tight expansion seal. The cup 40 gives the stressrelieving means 28 a shape which avoids any substantial increase in length of the bushing assembly. In another embodiment, Fig. 3, the compression springs 38 are disposed in an annular slot of an inverted telescopic member 64 which bears upward on the lower edge of the upper casing member 20 via a gasket 50, the slot being telescopically engaged with an annular wall 72 of a bushing support member 24 attached to the lower casing member 22. A fluid-tight expansion seal is provided by a flexible band 74 attached at its first end 76 to the cup 64 and at its second end 78 to the bushing support member 24. Such a flexible band (56, Fig. 2, not shown) may be used in the first embodiment instead of the O-ring expansion seal 54; furthermore in any embodiment it may be shaped to provide a larger space and thus act as an oil expansion chamber. In a further modification (Fig. 4, not shown) the springs (38) are compressed between internal projections or annular shoulders of an inverted cup (80) and of a bushing support member (24) which telescopes into the cup (80).
