    • 9925. Hobertson, R. B. May 1. Pianofortes; exercising-apparatus.-In pianofortes adapted for both normal and practising play, as described in Specification No. 17,982, A.D. 1902, the deadening bar or audible indicator A, Fig. 1, is a flat bar revoluble on its axis and provided with means such as the levers f, F and slide H to turn it with its flat face or one edge towards the hammers M, or the bar may have suit able faces and may be moved into one of three positions, corresponding to out of action, slight action, or full action, by means of pivoted levers and a three-stepped slide. The back rail for indicating the release of the hammers may be pivoted to the hammer rest, and may have a projection, which lies over a vertical slide that is moved by means of a horizontal sloped slide, or the projection may be linked to a lever that is raised or lowered by a pivotel lever operated by a stepped slide. The audible indicators A, B, Fig. 5, are located so as to be struck directly by the keys or by attachments carried by the keys, and can be thrown out of action, for normal play, or into action, for practising-play, by a horizontal slide. The indicator B is operated by a slide having a forked end to engage a stud on an arm attached to the indicator B. The hammer rest R is connected with the indicator mechanism A so that the hammers are brought against the strings in practising-play, or the rest R may be moved independently of the indicator A. Equivalent moving parts for operating the attachments may be used instead of horizontal slides.

    • This invention relates to a diesel fuel composition having enhanced lubricity, said composition comprising a major amount of a diesel fuel as base fuel blended with a minor amount of a nitrogen rich fraction characterised in that the nitrogen rich fraction is derived from a source material selected from (i) a solvent extract of a solid or semi-solid natural fossil, or, (ii) a refinery process stream or blend, the sulphur to nitrogen atom ratio in the nitrogen rich fraction being less than 4. The nitrogen rich fraction has an absolute nitrogen content of at least 1000 ppm by weight and this fraction is (re)blended with the base fuel is no more than 1% by weight of the total fuel composition. Methods of separating, recovering and reblending such naturally occurring nitrogen compounds can be installed or retrofitted at existing refinery and crude oil processing facilities without any substantial increase in production costs.
    • 本发明涉及具有增强的润滑性的柴油燃料组合物,所述组合物包含主要量的柴油燃料作为与少量富氮馏分混合的基础燃料,其特征在于富氮馏分源自选自 (i)固体或半固体天然化石的溶剂提取物,或(ii)炼油工艺流或共混物,富氮馏分中的硫与氮原子比小于4.富氮馏分具有 绝对氮含量为至少1000重量ppm,该馏分与基础燃料混合不超过总燃料组合物的1重量%。 可以在现有的炼油厂和原油加工设施上安装或改造分离,回收和重新分配这些天然存在的氮化合物的方法,而不会大大增加生产成本。
