Abstract: A cardiopulmonary resuscitating pump, comprising, a housing having a top wall (20), a bottom wall (21) and a side wall (22) in the form of a bellows which is capable of contracting and expanding under the application and release of an externally applied pressure to contract and expand the volume of a gas chamber (23) within the housing and having a gas inlet (48) through the bottom wall for drawing gas into the gas chamber and a gas outlet (43) through the bottom wall for discharging gas from the gas chamber to an associated oropharyngeal airway, whereby, in use a patient can be subjected to ventilation and external cardiac massage by appropriate operation of the pump whilst situated on the patient's chest.

Abstract: A first aspect of the invention is concerned with fuels and particularly jet and diesel fuels which comprise blends of substituted mono cyclohexane material and two ring non-fused cyloalkane material. The first material may be n-propylcyclohexane or n-butylcyclohexane. The second material may be nuclear substituted bicyclohexyl and may include cyclohexylbenzene. A second aspect of the invention concerns producing constituents for the fuel from heavy aromatic materials by breaking down the heavy aromatics to naphthas, separating light napthas and other constituents of the fuel before reforming a heavy naptha fraction to provide a BTX fraction which may be treated by hydroalkylation or pyrolysis to provide two ring non-fused cycloalkanes. The product may be enriched by hydrogenation.

Abstract: A process for production of hydrocarbons useful as fuels, comprises contacting a feed stream containing acetylene with a zeolite catalyst, whereby a reaction product containing said hydrocarbons is obtained. In a preferred embodiment the feed stream contains acetylene in admixture with one or more other compounds, for example inert gases, water, hydrogen, methane, ethane, and alcohols.
