Title: Fuel injection nozzle unit
IPC: F02M61/08
Filed: 1981-03-12
Abstract: The subject of the invention is a fuel injection nozzle unit with a valve member opening outwards, which has a stem and a head interacting with a seat.

Title: Method and apparatus for indirect determination of shear velocity from guided modes.
IPC: G01V1/44
Filed: 1983-10-14
Abstract: Methods and apparatus are described for estimating shear wave slowness of formations traversed by a borehole from guided wave acoustic log data. Acoustic energy is generated at a point in the borehole and received at at least four receiver stations spaced one from the other and from the generating point. Full wave forms of the received signals are produced and windowed to identify guided wavelets. Fourier transforms of the guided wavelets are obtained and from these determined the phase velocity and frequency of the guided wavelet. Values of formation density, drilling fluid density, drilling fluid slowness and borehole diameter are measured and a value of Poissons ratio may be estimated. A multi-dimensional matrix is established comprised of predetermined ranges of assumed values of frequency, Poissons ratio, drilling fluid slowness, drilling fluid density, formation density, phase velocity and borehole diameter. The measured data is fitted to the multi-dimensional matrix to obtain an estimate of shear wave slowness at the point in the borehole, and the estimate is recorded as a function of depth.

Title: Electric starting aid for compression ignition type IC engine - has heating element surrounding tubular extension to vaporise fuel as it flows through apertures, and orifice plate to remove frozen fuel
IPC: F02N/
Filed: 1983-11-30
Abstract: The aid has a body part to be mounted in an inlet manifold of the engine. A fuel inlet is formed in the body part for connection in use to a source of fuel. A fuel vaporiser includes an electric heating element carried by the body part which in use receives fuel from the inlet. An orifice controls fuel flow from the inlet to the vaporiser and is located in or adjacent the vaporiser at a position such that the component in which the orifice is formed is heated by the electric heating element. This minimises the risk of the orifice being blocked in use by frozen fractions of fuel. The orifice is defined in a plate located in a tubular portion of the vaporiser. The plate is cup-shaped and is held in the extension by frictional engagement of a skirt portion.

Patent ES-8505909-A1 (ES)
Title: Process for production of ethylene oxide and reactor suitable therefor.
IPC: F28F13/06
Filed: 1984-06-29
Abstract: Improved performance is obtained in a multi-tube reactor for oxidation of ethylene to ethylene oxide by providing a distribution zone for the coolant located downstream of the catalyst and a contiguous cooling zone. The effluent gases from the oxidation are cooled in the cooling zone by a fluid, which has been only slightly preheated and distributed uniformly in the distribution zone by contact with tubes in which the effluent gases are in low-turbulence flow. Uniform distribution of the coolant provides substantially equal cooling of the effluent gases in each tube, thus minimizing the variation in effluent gas temperature among the tubes. Preferably, the tubes in the cooling section are packed with inert particles to facilitate heat transfer, while the tubes are empty in the distribution section to reduce heat transfer.
