Title: Composition and method for metal surface refinement
Inventor: ZOBBI ROBERT G
IPC: C23C22/73
Filed: 1987-09-08
Abstract: A composition for use in the process of mass finishing of metal surfaces of objects, normally in a vibratory finishing process, utilizes a combination of oxalic acid, sodium nitrate, and hydrogen peroxide. The maximum concentration of the latter in an aqueous solution used in the process is limited to a value (0.05 gram mole/l) at which excessive dissolution of metal and pitting of the surface are avoided while, at the same time, cooperating with the nitrate to effect a substantial increase in the processing rate. Highly refined surfaces are achieved using the process in relatively short p eriods of time.

Title: Process for low level desulphurisation of hydrocarbons
Inventor: WILDT THOMAS DR
IPC: C10G25/05
Filed: 1989-07-21
Abstract: Hitherto, sulphur compounds have been removed from hydrocarbons by adsorption on activated carbon, silicates and zeolites. The use of a zeolite containing zinc and manganese is also known. However, all the existing processes are unsuitable for removing traces of sulphur from hydrocarbons. The novel process is thus intended to allow a deep desulphurisation of hydrocarbons. The deep desulphurisation of hydrocarbons is achieved by adsorption of the sulphur compounds on zeolites which contain copper, silver or zinc or mixtures thereof. Deep desulphurisation of hydrocarbons.

Abstract: A data queue system comprises plural memory blocks defined in memory and a data queue, which comprises a number of memory blocks each including a link to the following block in the data queue. A queue descriptor is stored in memory. It comprises information identifying the following: the final block in the queue, the memory location where the most recent read commit occurred, and an offset from a predetermined location in that memory block, the memory location where the most recent write commit occurred, and an offset from a predetermined location in that memory block, the size of the memory blocks, the memory location where the most recent write occurred, the number of unused blocks associated with the data queue, the number of memory blocks associated with the data queue which contain data to be read, the type of data queue, the memory location where the most recent read occurred, and the number of memory blocks which have been read since the most recent read commit. A method of managing data stored in a queue in memory comprises reading data from a head of the queue, updating the position of a latest read pointer to a location corresponding to the end of the data, transferring the data to a destination, and updating the position of a committed read pointer to a location corresponding to the end of the data upon receiving confirmation that the data transfer was successful. When there is insufficient data in the queue to meet a continuous-flow demand, the most recently read data is re-read.
