Title: Improvements in tubeless pneumatic tyre and method of making same
IPC: C08L23/22
Filed: 1954-05-31
Abstract: A vulcanized tubeless pneumatic tyre has an inner liner formed from a blend of (A) from 40 to 75 per cent by weight of a reaction product of 0.08 to 0.5 part of dinitrosobenzene with 100 parts of butyl rubber, and (B) 60 to 25 per cent of either natural or GR-S rubber. In forming the liner the butyl rubber may be first mixed with from 25 to 75 parts of carbon black per 100 parts of butyl and the mix then masticated with 0.1 to 0.2 part of para- or meta-dinitrosobenzene for a time ranging from three minutes at 400 DEG  F. to sixty minutes at 300 DEG  F.  The mix is then sheeted out and then blended with preferably 50-40 per cent of a mix of 100 parts natural or GR-S rubber, 25 to 75 parts of carbon black, and processing agents such as hydrocarbon oil, stearic acid and zinc oxide, other agents such as mercaptobenzothiazole disulphide, tetramethyl thiuram monosulphide and sulphur being added in the blending.  The blend is then calendered into sheet form and applied to the interior of a raw tyre carcase of natural or GR-S rubber coated cord fabric prior to shaping and vulcanizing.  Th ebutyl rubber used is preferably a copolymer of isobutylene with 0.5 to 5 per cent of isoprene.ALSO:A vulcanized tubeless pneumatic tyre has an inner liner formed from a blend of (A) from 40 to 75 per cent by weight of a reaction product of 0.08 to 0.5 part of dinitrosobenzene with 100 parts of butyl rubber, and (B) 60 to 25 per cent of either natural or GR-S rubber.

Title: Device for darning by means of sewing machines
IPC: D05B27/04
Filed: 1931-06-02
Abstract: 375,516. Darning by sewing-machines. HUMMEL, (nÚe EMMERMANN), M., 34, Eisenacherstrasse, Berlin. June 2, 1931, No. 16060. Convention date, Sept, 19, 1930. [Class 112.] A sewing - machine having means for rendering the feed mechanism inoperative so that it may be used for darning is so arranged that the tension of the presser spring on the presser foot may be changed rapidly between that required for sewing and the much smaller pressure required when darning. If desired, the pressure of the presser foot may be relieved altogether when darning. In one form shown, a fingeroperated lever 13 is pivoted to a collar 4 against which abuts the spring 3 which imparts downward pressure to the presser bar 2 and presser foot 1, and this collar may be raised and lowered, in a sleeve 5, between definite lever positions to ensure correct pressure on the presser foot according to the work being done. In a modified form, a spring, which may be adjustable in length or tension, is secured at one end to an abutment on the machine frame which may be vertically adjustable, and when the machine is to be used for darning the opposite end of the spring is engaged over an adjustable collar on the presser-ba,r to produce an upward pull to counterbalance wholly or in part the pressure of the spring which holds the presser foot to the work when sewing.

Title: Couplings rotatable assembly including two vaned wheels mounted on a
IPC: F16D3/68
Filed: 1973-04-06
Abstract: 1430863 Shaft couplings DUNLOP Ltd 14 March 1974 [6 April 1973] 16504/73 Heading F2U A resilient torque transmission coupling comprises an outer rigid member 11 formed with a bore in which is a rigid inner member 10, at least one intermediate rigid sleeve member 12 being in the annular space between the inner and outer members and elements 13a, 13b of elastomeric material are positioned between each successive pair of rigid members, at least some of the elastomeric material being in axially spaced regions separated by a distance at least twice the maximum spacing of the elastomeric material from the coupling axis. As shown, the inner and outer members are cylindrical and connected to a coupling member 14, and one intermediate member 12 is provided connected to a coupling member 15, three annular rings of elastomeric material (natural rubber as described) 13a being in compression between members 10 and 12, and three rings 13b of natural rubber being in compression between members 11 and 12. In an alternative embodiment two intermediate sleeves are provided, there being a further member radially outside the member 11 shown and connected to a coupling member equivalent to member 15 (Fig. 2, not shown). Axial movement of the coupling members 14, 15 towards one another is resisted by an annular ring 17 of resilient material, which may be on an intermediate sleeve rather than on the coupling member 14 as shown. The coupling is assembled by bonding the elastomeric material to the inner of the two members which it is to be between and sliding the outer member over it (and simultaneously compressing the elastomeric material). The assembly may be facilitated by the use of lubricant. The coupling is for inclusion in a drive-shaft of a vehicle and may be assembled in series with a coupling 30 as shown in Fig. 4 in which rubber elements 36 in pairs with a metal plate 37 are positioned between radially extending arms 33 of an inner ring 32 and cheeks 35 of an outer ring 34. This coupling 30 accommodates angular misalignment of the axes of rings 32 and 34 and is radially stiff, unlike the coupling of Fig. 1. The cheeks 35 may have means to prevent any radial movement of the rubber elements (Fig. 5, not shown). The elastomeric elements 13a and 13b need not all be of the same material, and some may have greater resiliency than the others. The assembly of the coupling of Fig. 1 may comprise contraction of an outer, or expansion of an inner, member to effect compression of the elastomeric material.

Title: Improvements in photographic processes for lithographic printing
Inventor: HEPHER MARTIN
IPC: G03F7/008
Filed: 1953-06-17
Abstract: 743,278. Photo-lithographic printing plates. KODAK, Ltd. June 16, 1954 [June 17, 1953], No. 16771/53. Class 98 (2). An azide sensitized water-permeable layer of a greasy-ink accepting material is imagewise exposed, washed to remove unexposed areas and treated with a solution of a salt of a multivalent metal, or an organic hardener such as formalin, to improve ink-acceptance of the remaining exposed areas. The method thus takes advantage of the good shelf-like of azide sensitized layers but avoids the reluctance of such layers to accept lithographic ink. In an example an aluminium foil is whirl-coated with an aqueous alkali-solubilized lactic casein solution sensitized with sodium 4 : 4<SP>1</SP>-diazido stilbene-2 : 2<SP>1</SP>-disulphonate, dried, exposed beneath a negative to mercury vapour lamps, washed with cold water and bathed for one minute in an aqueous aluminium sulphate solution. Numerous other bathing solutions are described for the purpose. Acid dichromate solutions impart ink-repellance to the bare meral areas, improve ink-acceptance of the casein areas, and appear to improve the bond between the latter and the metal. Glue or alkali-soluble polyvinyl phthalate may replace the casein. If a hydrophilic support such as a gelatin-baryta layer, surface hydrolysed cellulose ester, or anodized or phosphatized metal is used a simple treatment as with chrome alum or zirconium sulphate for the image areas suffices.
