Abstract: 504,194. Vehicle suspensions; resilient mountings; hinges. GOODRICH CO., B. F. Oct. 21, 1937, No. 28799. Convention date, Nov. 17, 1936. [Classes 108 (ii) and 108(iii)] [Also in Group XXV] In a vehicle wheel suspension in which thespringing is effected substantially entirely through torsional stress in a rubber body, the body 19 is arranged between an inner element or shaft 20 and a circumferentially-discontinuous sleeve structure, means being provided for holding the sleeve structure and rubber pressed towards the shaft. In the independent suspension for a steered wheel of a vehicle shown in Figs. 1, 2, the wheel structure 14 comprising the spindle 17, rotatable brake drum 15, and fixed spider 16 is carried at one end of an arm 18 the other end of which is secured to the shaft 20. The rubber body 19 is moulded between and preferably vulcanized to the shaft 20, and to the sleeve structure, in the form of sleeve sections 20a, 206, which is readily compressable to facilitate insertion in an eye 21 on an arm 13 rotatable about the steering pivot 12. The sleeve structure is a tight tit in the eye 21 but additional retaining means such as set screws, keys, &c, may be provided. An auxiliary sleeve 22 may be inserted between the sleeve structure 20a, 20b and the eye. The diameters of the rubber body and of the shaft 19 are reduced towards the ends of these parts in order to lessen the stress in the rubber at the end surfaces. An auxiliary shock-absorber 27 rigidly secured by a bracket 28, Fig. 2, to the eye 21 and operated by a lever 29 pivoted to' the brake spider 16 may be provided. Instead of the resilient mounting being supported centrally by the single eye 21, the arm 13 may be bifurcated so as to support the mounting at each end by two narrow clamp-like members. In another construction an auxiliary sleeve similar to the sleeve 22 wholly encloses the resilient mounting. The inner and outer metal elements and the rubber may be provided in two or more sectional units each consisting of a half or sector of the shaft, rubber, and sleeve.

Filed: 1963-07-23
Abstract: 974,465. Sheet explosives. E. I. DU PONT DE NEMOURS & CO. July 23, 1963 [July 23, 1962], No. 29108/63. Heading F3A. Explosive material mounted on a flexible tape can be folded on account of a series of slits cut across the tape along the location of the desired fold. A rubber impregnated paper tape has an explosive coating 1 of thickness between 10 and 30 times that of the paper and a series of slits GG<SP>1</SP> to MM<SP>1</SP> are cut through the explosive material but not necessarily through the paper tape, the length of the slits being at least four times the thickness of the coating. The tensile strength of the backing is at least one and a half times that of the explosive coating. The slits are cut in staggered formation as shown with circular ends to dissipate any tearing forces and at an angle of between 15 and 40 degrees to a folding line F, F<SP>1</SP> which passes approximately through the centre of each slit. On folding, the tape between the slits is free to twist and so avoids many of the lateral stresses which would be exerted on an unslit width. Ignition is either by blasting caps or line-wave generators and the explosive material may consist of a cap sensitive crystalline explosive mixed with a binding agent of an organic rubber and a thermoplastic terpene hydrocarbon, or of pentaerythritol tetranitrate, a trialkyl ester of 2-acetoxy-1,2,3- propanetricarboxylic acid and soluble nitrocellulose. The slits may also be curved or semicircular instead of straight. Specifications 857,175, 876,951 and 878,196 are referred to.

Title: Improvements in or relating to diesel fuel compositions
IPC: F02B47/00
Filed: 1949-11-15
Abstract: A minor proportion of either a mono-, di-or tri-nitro aromatic amine or of a nitro- or di-nitro phenol is added as a stabilizer to a diesel fuel containing a minor proportion of an organic peroxide. The term "peroxide" includes organic hydroperoxides, e.g. tertbutyl hydroperoxide, esters of such, particularly of alkyl hydroperoxides with organic acids particularly aromatic acids, and esters of corresponding alcohols and organic peracids. Preferred compounds are those having an alkyl group of 3-6 carbon atoms joined through a per-ester group to an aryl group of 7-11 carbon atoms, and having the general formula R1-O-O-CO-R2 where either R1 or R2 is the alkyl group and the other is aryl, as in tert.-butyl perbenzoate. Preferred stabilizers include: p- and/or o-substituted-o-nitraniline, o- or m-substituted-p-nitraniline, m-nitraniline, p- and di - o - substituted - m - nitraniline, o-substituted-o, p-dinitraniline, p-substituted-m-dinitraniline, o- and N-substituted-o-nitraniline, p- and N-substituted-m-nitraniline N-substituted-trinitraniline, o- or m-substituted-o, p-dinitrophenol, o-substituted-m, p-dinitrophenol, m- or p-substituted-o-dinitrophenol, o-substituted-o, p-dinitrophenol, -o-nitrophenol, and -p-nitrophenol, p-substituted-o-nitrophenol, m-substituted-p-nitrophenol, and o, p-disubstituted-o-nitrophenol.  In these compounds the substituent groups may be alkyl groups of 3-15 carbon atoms, substituted cyclopentyl or cyclohexyl groups of 6-15 carbon atoms or substituted or unsubstituted aryl groups of 6-15 carbon atoms. The stabilizer may be added to the fuel in amounts of 5-50 lbs. per 50,000 gallons of fuel, while the peroxide may be added in amounts of about 0.5-2 per cent by weight of fuel.  The additions may be made to all diesel fuels, but are particularly applicable to those of boiling range about 350 DEG F to 650 DEG F.  In an example samples of a diesel fuel base stock consisting of gas oil derived from thermal cracking having an initial B.P. 370 DEG F, mid-B.P. 468 DEG F and final B.P. 594 DEG F containing 1 per cent of tert-butyl perbenzoate are compared with samples of the same fuel containing in addition to the peroxide 42 lbs. 2, 4 dinitro-6-cyclohexyl phenol per 50,000 gallons of fuel.
